1,134,212. Thermal regenerators; heat storing apparatus. GAS COUNCIL. 8 Dec., 1965 [9 Dec., 1964], No. 50032/64. Headings F4K and F4U. A thermal regenerator comprises two U-shaped ducts containing respectively thermal storage beds 14, Fig. 2, 15, Fig. 1, shown as beds of refractory pebbles, each bed having a fluid inlet and fluid outlet aperture 16-19, respectively located at opposite ends of the bed, and all these apertures lying in a common surface which may be curved but is preferably plane being defined as shown by the upper surface of a plate member 9. Primary (heating) fluid is generated by a burner 20, Fig. 2, and after passing through one of the beds, e.g. the bed 14 as shown, is discharged through a flue 24. Simultaneously a secondary (heated) fluid (unspecified) passes through the other bed from an inlet 26 to an outlet duct 31 upstream of which is a heat transfer device 30 for maintaining a substantially uniform outlet temperature of the secondary fluid at the duct 31. The device 30 consists of liquid-solid phase-change refractory tube elements 34 which initially absorb heat from the heated secondary fluid when this is at its highest temperature having passed through a freshly heated bed. Subsequently when the bed begins to cool and the temperature of the secondary fluid falls, the elements 34 give up absorbed heat to this fluid. The beds 14, 15 are intermittently moved (e.g. rotated or oscillated on a turntable 6) so that each bed is traversed alternately by the primary and secondary fluids, and during the changeover when the burner 20 is shut down and both beds are temporarily cut off from the primary and secondary fluid streams (see Fig. 4b, not shown) a valve 33, Fig. 1, is opened to permit secondary fluid to pass direct from the inlet 26 to a pipe 29 downstream of the beds, and thence over the heat transfer device 30 which heats this fluid, to outlet 31; thus a supply of heated secondary fluid is maintained during the changeover period. Hydraulic jacks 10 maintain the sealing pressure between the relatively movable elements 8, 9 when the beds are operative. The bed which has just been heated may be purged using either a flow of secondary fluid, or a vacuum source, during the changeover period.

Method fo protecting metals against atmospheric corrosion

en
|
1414025 A method of protecting metal objects against corrosion INSTITUT FIZICHESKOI KHIMII AKADEMII NAUK SSSR 9 Nov 1973 52027/73 Heading B8C A method of protecting the surfaces of metal products, e.g. of complex configuration, against atmospheric corrosion by vapour phase inhibitors in a sealed space, is characterized in that a porous carrier is located in said space, the carrier being a silica gel, or a zeolite and containing a vapour phase inhibitor, in the form of a primary, secondary or tertiary amine, a mixture of amines, or derivatives of amines. The silica gels and zeolites, which have a high adsorbtional capacity, provide a large store of vapour phase inhibitor with a small volume of porous carrier, the silica gels and zeolites having pores of a diameter from 20-140 Š and 4-15 Š, respectively. Primary amines-cyclohexylamine, benzylamine; secondary amines-hexaethyleneamine, dicyclohexylamine; tertiary aminestriethylamine, cyclohexylamine carbonate, as well as mixtures of these amines, are used. The silica gels and zeolite are dried at 200- 300‹ C., cooled in a closed vessel up to 15.20‹ C., and then immersed in the vapour phase inhibitor or, in its solution, in an organic solvent such as spirits, or acetone, the released heat being allowed to escape. The inhibitor, or its solution, may be applied to the carrier in portions up to complete saturation, any excess amount being removed by way of natural drying, or by passing the carrier through absorbent rollers. The silica gel, or zeolite, loaded with vapour phase inhibitor, can be placed in perforated cartridges which are made of glass, cardboard &c., which does not interact with the inhibitor. The cartridges are adapted, e.g. to be placed into the cavity of a steam boiler, kept in storage as a reserve for a long time or to be placed in a polyethylene container which sealingly contains, e.g., a number of tightlypacked, electronic, precision instruments.

1281090 Automatic control of speed ROBERT BOSCH GmbH 27 Oct 1969 [25 Oct 1968 (2) 7 Nov 1968] 52462/69 Heading G3R An electronic governor for an internalcombustion engine, e.g. a diesel, comprises a regulator having an operational amplifier 27 having non-inverting and inverting input terminals, to the latter of which is connected an engine speed signal and a feedback network R which determines the governor characteristics. As shown, a speed reference voltage from a pedal operated potentiometer is applied to the non-inverting input 29 and a voltage from a tachogenerator is applied to a speed input 33. The tachogenerator may produce pulses or an A. C. signal whose frequency is proportional to speed, and this is converted to a D.C. voltage by an RC circuit Figs. 2 and 3 (not shown). In the feedback network shown a capacitor 36 provides a differential component and a potentiometer 38 controls the slope of the speed/fuel supply characteristic. The output of 27 controls the fuel injector by an electrohydraulic system of an electric servomotor, and injector position feedback is provided. A number of alternative embodiments are described Figs. 7... 20 (not shown) for operating governors which control speed throughout the range and/ or the idling and maximum speed characteristics only and include arrangements for producing non- linear features such as a kink in the idling characteristic. This is produced by a diode circuit whose conduction is determined by an adjustable resistor network Fig. 7 (not shown) or an auxiliary voltage source, Fig. 10 (not shown). Also positive feedback may be used to produce a positive slope to the load limiting characteristic, Fig. 11 (not shown) and a further diode circuit used for temperature compensation, Fig. 17 (not shown). In Figs. 21 to 32 (not shown) separate amplifiers are connected in parallel with the main amplifier to produce the required characteristics, and these are further modified by various transistor circuits between the tachogenerator and the amplifier input.

1,075,340. Rotary vacuum-pumps. CENCO INSTRUMENTS CORPORATION. Dec. 29, 1964 [July 22, 1964], No. 52713/64. Heading F1F. [Also in Division F2] A rotary vacuum-pump of the outwardly-sliding radial-vane type comprises a low-pressure stage 22 and a high-pressure stage 24 with a plate 24 therebetween, the two stages being sealed by oil situated in a space 32 externally thereof. The stage 24 includes an intake port (49), Fig. 7 (not shown), which is connected to a cylindrical chamber (48) containing a pumping rotor (50) by a hollow block (47), and an exhaust port (72) connected to an intake port (95), Figs. 1 and 8 (not shown), for a cylindrical chamber (90) containing a pumping rotor (93) in the stage 24 by an opening (88) in the plate 26, an exhaust port (94) for the chamber (90) being controlled by a non-return valve (96), Fig. 4 (not shown), (see Division F2). The rotors (50, 93) are attached to a common driving-shaft 33 and are made hollow so that oil for sealing and cooling purposes can pass therethrough, the oil being taken from the space 32 by the action of the rotors through a hole 116 in a hollow end-cap 112 attached to an end-plate 110 for the stage 24, a passage 120 in said endplate, a passage 104 in the plate 26 and a passage 126 in an end-plate 82 for the stage 22, which passage communicates with the interior of a hollow end-cap 122 attached to the plate 82. While oil passes through interior of the rotor (93) gas mixed therewith is ejected by centrifugal action and escapes into the opening (88) through a groove (130), Figs. 1 and 4, in the plate 26. Sealing of a pair of diametrally-opposed radialvanes 52, 53 in each rotor is effected by centrifugal displacement of the oil within the rotor, surplus oil on the exterior portions of the rotor and the vanes being entrained with the gases being pumped. Gases and oil entrained therewith that are discharged from the stage 24 through the port (94) enter the space 32 whence the gases escape through a cowl or bonnet attached to a portion 29 of an external housing for the stages. The stage 22 may be charged with ballasting gases e. g. air, at atmospheric pressure through a pipe 36. Pressure-relief valves 86, (86') are provided on the plates 82, 110 at the ends of passages 84, (84') communicating with the ports (72, 95), respectively. The vanes are biased outwardly in a radial direction by springs 68 mounted on pins 67 attached to a tongue or so called leg 65 on one of the vanes in each pair thereof, said pins being slidingly engaged by radial bores in a tongue on the other vane. The tongues 65 engage with slots 70 in the shaft 33. The pump may be modified to include additional stages operating in parallel with the stages 22, 24.

1456260 Crystallizing fructose SUOMEN SOKERI OSAKEYHTIO 9 Dec 1974 [28 Jan 1974] 53056/74 Heading B1G [Also in Division C2] Fructose crystals having a crystal size of 200 to 600 Ám are obtained by crystallizing fructose from an aqueous solution thereof, containing at least 90% by weight of dry substance of which dry substance at least 90 percent by weight is fructose, in a process which comprises (a) providing such a fructose solution (b) adjusting the pH of said solution to 4.0-6.0, preferably 4.5-5.5, (c) bringing the aqueous fructose solution to a temperature at which it is saturated with respect to fructose, (a) adding fructose seed crystals to the solution, (e) lowering the temperature of the resulting mass at a controlled rate to cause the mass to be supersaturated with respect to fructose and to bring about an increase in the crystal size of the seed crystals without substantial formation of new fructose crystals and (f) separating the fructose crystals from the mass when the crystal size is 200-600 Ám. The process may be carried out continuously using as seed crystals, crystals taken from a previous crystallization and recrystallization may be accelerated by blowing warm dry air on to the surface of the mass to evaporate water therefrom during crystallisation. The rate of crystallisation of fructose may be increased by the addition to the solution of 2-4% by weight, based on the sugar solids, of methanol, ethanol, and/or isopropanol.

Electrodes 23, 25 preferably of chromecopper-chrome but alternatively of tin oxide, gold, aluminium, copper or silver, either in the form of wires or formed by photo-etching, vacuum deposition or stencil screening on substrates 31 or 33 of soda-lime-silicate glass are covered with layers 27 and 29 of lead borosilicate glass. A blackening agent is incorporated in layer 29 by adding a small percentage (e.g. 2%) of a mixture of iron and cobalt oxides to the glass frit of the layer prior to firing. The resulting layer also reflects light. The surfaces of the layers 27 and 29 bounding the discharge space 45 are protected by a refractory coating (not shown) of MgO which also exhibits high secondary emission. Alternatively the MgO may be included in the glass composition. The discharge space 45 is filled with a mixture of neon and argon. The spacing between the layers 27 and 29 may be maintained by spacer rods of hard glass which may either be transparent or may conform in appearance with layer 29.

A method of inducing rainfall in an arid area close to the sea comprises the building of a floating barrage impervious to sea-water extending outwardly from the coast, with the aim of deflecting away from the coast currents of cold water flowing along it, and thereby producing, adjacent to the coast, an area of warmer water which will result in increased evaporation and increased precipitation over the adjacent land. The barrier may consist of a series of cylindrical hollow floats or a continuous bouyant inflatable hose from which hang sheets of rubber or canvas the lower edges of which are weighted, the hose or the floats being connected at spaced intervals to buoys, which may be lighted for nagitation purposes, and which are anchored by cables to blocks on the sea-bed. The sheets may be of about 100 ft. in p depth and the barrage may be of several miles in length.

1,158,227. Discharge lamps. WESTING- HOUSE ELECTRIC CORP. 24 Nov., 1967 [19 Dec., 1966], No. 53531/67. Heading H1D. A focusing member 23 is mechanically fastened to a body portion 21 of a lamp base B in adjustable eccentric relationship to enable any axial misalignment produced when the body 21 is attached to an elongated sealed end portion 13 of the lamp to be reduced to a specified tolerance. A lamp lead 19 passes through an aperture in the body 21 which is secured to the lamp by a clamp C which compresses a slotted end of the body around wet asbestos tape wound on the arm 13 and then allowed to dry. The member 23, which also forms a socket-engaging member when the lamp is mounted in a fixture in association with a reflector, is mounted eccentrically on a stud protruding from the body 21 and is secured by a lock washer 37 and cap screw 39. Adjustment is effected by supporting the lamp by members 23, 24 in V-shaped notches 46, 47 in members 44, 45 of an optical apparatus (Fig. 3, not shown) and rotating the members 23 and 24 individually while observing the position of the lamp electrodes in the fields of two microscopes mounted at right angles to each other. A wide range of misalignment can be covered by using members 23, 24 with a correspondingly wide range of eccentricities.

Apparatus for making a tabe by helically winding an elogate strip
|
en
|
The apparatus serves for the production of tubes by winding up a strip, in particular a strip of sheet metal, helically using a winding device. To guide the strip (1) in a circle to form a strip coil (10), this winding device (7) has two joining rollers (5, 6), which are arranged at the strip entry point, engage on the two broad sides of the strip (1) and join together the strip coils (10) adjacent to one another in the tube. In order to be able to produce tubes in precisely the desired, constant or varying, diameter with this apparatus, the peripheral speed of one joining roller can be varied relative to that of the other joining roller. Thus, the joining roller on the inside of the strip coil can be varied in its rotational speed and the joining roller on the outside of this coil can be driven at a constant rotational speed. <IMAGE>

1414659 Valves CLIPPARD INSTRUMENT LABORATORY Inc 22 Nov 1972 [10 Dec 1971] 54116/72 Heading F2V [Also in Division G3] A valve construction comprises a standardized "quick mount" hollow tubular housing which is provided with passageways 33 in the wall of the housing which connect the external ports 59 of a valve mechanism inserted in the housing via ports 48 to passages 14 in a base 10. The ports 48 are made as desired. The valve comprises various standardized elements which are stacked inside the housing and held in position by a cap 20 provided with the housing. Various types of valves can be assembled but all ports of the valves open into a respective annular groove in the external surface of the valve. A port 48 is made at the same longitudinal distance to the required passage by cutting (prior to insertion of the valve) for example by a rotary cutter. The housing has a keyed projection 44 to effect proper orientation of passageways relative to the base. The valve shown in Fig. 4 is a piloted four-way valve. Fig. 5 shows a shuttle valve 81 and a check valve 82, in this case completely separate. Other forms of shuttle valve and piloted multiway valves are described; in one of the latter the cap is provided with a transparent window so that the position of the spool is visible while another has a passage which is ported twice at different longitudinal positions with a flow restrictor therebetween. In Fig. 7 the cap is provided with a knob 142 for an adjustable needle valve 140 which is provided in the port 141 of a time delay flow control valve 126. The valve 126 permits free flow from passage 145, past check valve 138, to passage 148 but restricts flow in the opposite direction. This fluid is bled slowly past the needle valve to passage 45 which is connected to the volume chamber 156 and this delayed pressure build up is used to retard the operation of a member actuated by the pressure in passage 145. The invention can also be used as a fluidic valve as shown in Fig. 9 when a plug provides the fluidic circuit of an amplifier with similar connection to the housing passages as previously described.

1279084 Reactors UNITED KINGDOM ATOMIC ENERGY AUTHORITY 3 Nov 1969 [15 Nov 1968] 54439/68 Heading G6C A liquid metal (e.g. sodium) cooled fast breeder reactor has a core configuration which includes a central cylindrical breeder region, a first fissile region which completely embraces the central breeder region, a second fissile region at least partially surrounding the first fissile region with axial and radial clearance, an inner breeder region occupying this clearance, and an outer breeder region extending both axially and radially from the outer boundary of the second fissile region to the cylindrical core boundary. In a preferred construction, shown in Fig. 2, the second fissile region only partially surrounds the first fissile region, the " corner " fissile portions of a wholly surrounding fissile region being replaced by breeder material. The annular region between the first and second fissile regions, i.e. the region bounded on the inside by lines 13, 13<SP>1</SP> and on the outside by lines 14, 14<SP>1</SP>, is therefore entirely breeder and of full core height. Because of the lower heat rating of breeder pins, it may comprise fuel pins of greater diameter than those which include fissile material, thus enabling a higher breeder/ structural material ratio to be achieved. The radially outermost region comprises similar fuel pins. Preferably, the fissile material is mixed U and Pu oxides, and the breeder material is UC.

1410363 Automatic control SONY CORP 27 Nov 1972 [29 Nov 1971] 54796/72 Heading G3N [Also in Divisions H1 and H3] In a broadcast receiver comprising an input circuit 1-3 Fig. 1 for receiving radio signals, a local oscillator 1, a divider 9 and a counter 14, the preselected contents of the counter 14 is varied in accordance with the number of pulses received from a pulse generator 92a, Fig. 16 for varying the dividing ratio of the divider 9 in dependence on the contents of 14, a frequency and phase comparator 10 compares the output from the divider 9 with a reference signal 11 and a control circuit varies the local oscillator frequency in dependence on the output signal from the comparator 10. A circuit CTL connected between the input circuit and a memory 59 provides a pulse in response to the output signal from the input circuit and applies the pulse to the memory whereby the existence of received radio signals is memorized by the memory 59. The radio or TV receiver has RF amplifier, mixer and a local oscillator 1 having a variable capacity diode; an IF amplifier 2, an FM discriminator 3 a muting circuit 4 and a stereo multiplexer 5. The output frequency of the local oscillator 1 is fed via a mixer having a crystal oscillator 7, a divider 8 and a <SP>1</SP>/ N divider 9 to a frequency and phase comparator 10 which is also fed by a reference signal generator 11 via a divider 12. From the comparator 10 is obtained a direct voltage which is supplied as an oscillating frequency control voltage to the local oscillator 1. By changing the divide ratio N of the divider 9 FM waves with a frequency band are selectable. The divider 9 includes binary counters (11a, 11b, 11c,) Fig. 2, (not shown), a discriminator (15) and a gate (13) and the division ratio N is selected by a station select counter 14 including counters (14a, 14b, 14c). The contents of the station select counter 14 at (19a, 19b, 19c) are fed to a binary decimal decoder 20 the output of which feeds an RF indicator device 23 including indication tubes and feeds a matrix decoder 24. The binarydecimal decoder 20 and the matrix decoder 24 are described in detail Figs. 4A and 4B, (not shown). The matrix decoder 24 includes OR gate transistors (25) further described in Fig. 5 (not shown) and AND gate transistors (38) further described in Fig. 6 (not shown). The outputs from the matrix decoder 14 feed a lamp panel display 47 and a memory 59N. The lamp panel display 47 includes channel indicating elements such as neon lamps (L1-L70), Figs. 7 and 8 (not shown) and associated lamp push switches SW1...SW70. The neon lamps L1...L70 become ignited when the case made of glass and concerning each lamp is pushed. The state at which the switches SW1...SW70 are in the on condition is detected by a station select circuit (48) Fig. 9 (not shown). The memory 59N includes a 70 bit memory matrix having variable threshold MAOS FET (Q1...Q70) Fig. 12 (not shown) and is controlled by a memory control circuit (63) Fig. 13 (not shown) which has write, read and memory select switches (67a, 67b, and 67m). A control circuit CTL has self-light emitting buttons (87a-87e) Figs. 14 and 15 (not shown) for controlling the tuning and (88a-88e) for controlling the memory 59N. A control circuit for station search mode Fig. 16 includes a control button 88e, a monostable delay circuit 90, a flipflop 91, a station pulse generator 92a, a station search circuit 93 and a monostable write signal generator 101. The station search circuit 93 includes a D.C. level detector (95) Fig. 18 (not shown) fed from the output of the FM discriminator 3 and AND gate 96 fed from a muting control signal obtained by rectified output of the IF amplifier 2. The output from the level detector (95) feeds the AND gate (96) the output from which feeds an integration circuit (98). Operation of station search button 88e causes pulses to be generated by station pulse generator 92a which operates the station select counter 14 to scan through the RF range whereon the circuit is reset. If the receiver is in the tuned condition the pulse generator 92a is momentarily stopped so that the neon lamp in the panel display 47 corresponding to the tuned frequency is ignited for a longer period. When a station is present the memory 59N is written in succession. A scan mode circuit indicating all of the stations received in the FM band with the aid of the panel display 47 which only ignites the lamps corresponding to these stations is disclosed Fig. 21 (not shown). This scan mode circuit includes a station pulse generator (92b) a memory output discriminator (103) and a memory output delay circuit (104). A station may be selected by pushing the neon lamp corresponding to that station so that the scanning is stopped when this neon lamp is ignited. A control circuit relating to shift and step modes is disclosed Fig. 23 (not shown) which includes station pulse generators (92c, 92d, 92e) and a repeat monostable signal generator (92f). When a button (87b) is pushed the frequency changes to the next station. When a button (87c) is pushed the next tuning scan is affected at a given time without pushing the other buttons. When a button (87d) is pushed the frequency is shifted at a constant speed. When a button (87e) is pushed the frequency changes in a step manner. Another memory 59P similar to the memory 59N may be used for storing the desired stations beforehand.

1278976 Ink jet printers RECOGNITION EQUIPMENT Inc 10 Nov 1969 [10 Feb 1969] 54825/69 Heading G4H In an electrostatically deflected ink jet printer including an ink drop forming unit 10a, a servo loop is provided for adjusting the phase of a charging voltage applied to the ink drops to ensure synchronism between the instant of formation of the drops and the phase of the drop charging voltage. A high-frequency sine wave generator 331, controlled by a system clock 316 energizes a piezo-electric crystal 105 which vibrates a nozzle 104 to form the ink drops. The drops pass between charging plates 109 and are deflected in proportion to their charge by plates 110, 111 before striking a moving document 100 on which a series of eight drops forms a printed bar 114. The plates 109 are connected to a stair step voltage generator 323 via a " write " amplifier 326 gated by signals from a computer 336 having a data input from a tape 343. To ensure that each drop receives a charge corresponding to the successive levels of the stair step voltage and not to a voltage between these levels, a calibration cycle is included between the printing of successive documents. During this calibration period the amplifier 326 is turned off and a gated amplifier 327 is turned on by the computer 336. The amplifier 327 is connected to a ramp function generator 335 which charges the drops, the drops being collected by a catcher 112. The voltage on the catcher and a reference voltage 304 are fed to a difference voltage amplifier 302 in a voltage comparator or phase detector 301 having " up " and " down " phase outputs 307, 308. These outputs are connected to an accumulator 309 controlled by a pulse from a clock 310, the accumulator being connected to a D/A converter 313 and a phase shifter 315. A counter 321 to which the phase shifter is connected determines the number of drops in each bar. The phase shifter controls the phase delay between the charging voltage on the plates 109 and the crystal excitation voltage output of the generator 331.

1437503 High voltage step-wave generators THOMSON-CSF 27 Nov 1973 [28 Nov 1972] 54992/73 Heading H3T To generate a stepped high voltage (Fig. 4, not shown) a capacitor C11, Fig. 3, is held charged to an initial level OR by a source 1 through an inductance L1, and is then successively charged to higher levels UJ, UV by repeatedly charging a capacitor C2 and discharging it through a winding L3 coupled to L1. The source 1 is of the order of 5 kv and the source (not shown) charging C2 through an inductor L2 is of the order 150 v, the resulting stepped voltage being used to operate a polychromatic cathode-ray tube (not shown). The repeated chargings of C2 are effected by a transistor I2 controlled by a circuit 20, and its dischargings by a thryistor I3. At the end of the third step (UV) C11 is discharged by an arrangement of thyristors I1a to I1p which are protected from overload by avalanche diodes D1a to Dlp and are controlled by a transformer T2 receiving a control signal S5. A further capacitor C3 is repeatedly charged via I4 and discharged by I5 through a further winding L5 to "top-up" the charge on C1. A feedback control circuit R2, R3, 25, 26 provides output voltage regulation.

[Also in Divisions D1 and F2] A label is secured to an article by apparatus (see Division D1) adapted to pass a length of flexible filamentary thermoplastic material, issuing from a supply thereof, through the label and article, to sever said length from the supply, and to deform the protruding ends of the cut length by heating. Labels 26, stacked in a hopper 48, are fed consecutively on to ledges 28 flanking a V-shaped groove 30, to be secured thereat to fabric supported above groove 30 by wire arms 84. The labels in hopper 48 are supported by the front end of a slidable bar 54, the rear end of which is rigid with the piston-rod 60 of a pneumatic cylinder 62. Pressure is normally applied to the latter for positioning bar 54 to the left, when a shoulder (66), Fig. 7, thereon abuts the lowermost label. A reversal of pressure thereby shifts said label on to ledges (68), and, on retraction of bar 54, said label abuts a shoulder (74) while the now lowermost label abuts shoulder (66). In operation, a plate 96 on a lever 94 is manually depressed to actuate a microswitch. Pressure to cylinder 62 is thereby reversed, whereby bar 54 moves forward to transfer a label from the ledges (68) to the ledges 28.

An apparatus for the sub- or super-atmospheric treatment of continuous length sheet like material has a liquid seal 4 at the inlet for the material and the material is hermetically clasped between a pair of moving endless bands 1 and 1' as it passes through the liquid, the bands passing over return rollers 3" immediately adjacent the material outlet side of the liquid seal so that the bands barely pass into the treatment zone 5. The liquid of the seal is a low fused molten metal. The hermetic sealing effect between the belts 1 and the material 2 is enhanced by installing air suction means between the belts immediately before they are brought into adherence by rollers 3'. The perimetric edges of the bands may be composed of magnetic rubber, or alternatively co-operating grooves and ridges may be provided on the bands 1 and 1'. The bands are made of a material which can withstand the molten metal, e.g. rubber or synthetic resins. The outlet of the treatment zone 5 can be provided with a similar sealing arrangement, or alternatively the same liquid seal can act as inlet and outlet for the material (Fig. 3, not shown). Where the apparatus is concerned with dyeing a dye bath 8 may be arranged externally (Fig. 1) or internally of the apparatus. A single batch or double batch roller can be provided within the treatment chamber (Fig. 5). The sheet can be reciprocatively treated by winding and unwinding means disposed externally of the apparatus.

1401109 Camera mounting ASAHI KOGAKU KOGYO KK 29 Nov 1973 [30 Nov 1972] 55463/73 Heading G2A A camera mounting assembly comprises a stationary member 32, a movable member 20 pivotable relative thereto, one member having a number of position detecting means and the other a number of position setting means, one of the sets of means being externally adjustable, so that photographing conditions can be pre-set, with a corresponding control output when the two sets of means are in a predetermined position. As shown, a camera 19 having a pre-set focusing lens barrel 19' is carried by a support 18 pivotally mounted on shaft 20. Discs 23, 24 and 25 are rotatably mounted on shaft 20, and can be secured in any position by respective clamps 26, 27, 28. A base member 32 is mounted on a tripod 33, and shaft 20 can be secured to member 32 in any given position by a screw 34. The upper part of member 32 is formed as a cover 35 having windows 36, 37, 38 through which clamps 26, 27, 28 extend, and adjacent the windows are indicia 39, 40 and 41. Each disc has a notched portion 29 (see also Fig.4 not shown) which, when the disc is rotated to the appropriate position, co-operates with a switch (such as 42 or 43). A potentiometer 46, which is associated with switch 42, and also with a particular focal distance, can be set at a predetermined value which corresponds to this distance. When the notch 29 of disc 23 engages with the switch 42, a circuit is completed which automatically adjusts the focus of the lens to that distance. The position of disc 23 is so fixed, by clamp 26, that notch 29 and switch 42 will be aligned only when the camera is pointing in a particular direction, e.g. at the object to be photographed. Thus only when the camera is pointing in the right direction will the focus be automatically adjusted to the predetermined value. In the arrangement shown, there are three potentiometers, 46, 47, 48, corresponding to the three discs 23, 24, 25, so that three different focal distance settings are available. Other photographic conditions, such as exposure values or diaphragm settings, may be controlled in the same way.

1,141,490. High voltage switches; actuation of switches. S. & C. ELECTRIC CO. 13 Dec., 1966 [20 Dec., 1965], No. 55701/66. Heading H1N. In a high voltage circuit breaker two rectilinearly movable series connected contacts 47 are operated by a rotary double armed lever 66 driven by a spring. Two series connected interrupter units 32, 33 each housing two series connected main breaks 45 and two series connected auxiliary breaks 53 in parallel are mounted on opposite sides of a mechanism housing 34. The movable contacts 47, 55 are coupled by rods 49, 59 and links 62, 76, 77 to a pair of double armed levers 66, 80 loosely mounted on a shaft 67 attached to a rotatable insulator 13 which also supports the housing 34. Initial rotation of insulator 13 anticlockwise (from above) causes an arm 137 to release a roller latch (127) (Fig. 10, not shown) allowing lever 66 to rotate clockwise under springs 102, 103. If the contacts stick further movement of arm 137 causes positive actuation of lever 66. The second lever 80 is coupled to lever 66 by a coiled torsion spring (83) (Fig. 5, not shown), which is stressed by the initial rotation of lever 66, lever 80 being held by a roller latch (171) (Fig. 11, not shown) until the main contacts have separated. On further rotation of lever 66 latch (171) is released and an abutment on lever 66 strikes lever 80 causing rapid opening of contacts 53. Shock absorbing buffers 186 (187) stop the lever 66, 80. Continued rotation of insulator 13 opens a series isolator (28, 29) (Figs. 1, 2, not shown). Towards the end of the rotation, an abutment 150 on arm 137 drives lever 66 back to the contacts closed position, restressing springs 102, 103 and resetting the roller latch (127). Lever 66 is arranged to rotate an indicator drum visible at a window 207. Springs 102, 103 are adjustable by a toothed disc 104. The interrupter units which may be as described in Specification 966,110 are sealed and contain SF 6 , the auxiliary breaks having blast action. The insulator 13 as well as other fixed supporting insulators (14, 15) carry voltage grading rings 37, 38, 40, 41.

1474637 Measuring parameters of networks L P RUSSIN 27 Dec 1974 55971/74 Heading G1U A device for measuring the transfer parameters, e.g. amplitude ratio; phase shift; response time; output frequency, of a network comprises a source of oscillations connected to the network under test, N.U.T., to a variable phase shifter, an indicator connected to the output of a difference amplifier whose first input is connected to the phase shifter and a changeover switch connecting the source output to phase shifter input and the output of the N.U.T. to the second input of the amplifier or vice versa. In Fig. 2 the N.U.T. is a control circuit 2. The test operation is as follows:- (a) switch 6 set to positions 8, 58, 59 and capacitor 27 in phase shifter 5 set to zero-, (b) indicator 4 reading taken; (c) switch 6 set to 7, 59, 60; (d) resistor R34 in one input to difference amplifiers 3, comprising inverter 32 and adder 33, adjusted until indicator 4 reads the same as in (b), the channel gains are now equalized and the value of R34 indicates the ratio of input to output amplitudes; (e) switch 6 set to 7, 8, 59 and capacitor 27 adjusted until indicator 4 is a minimum (f) the phase shift across the circuit 2 is then calculated from the values in phase shifter 5; if the phase-shift is greater than - 180 degrees, the channels are reversed by setting switch 6 to positions 9, 10, 60 at step (e). To measure response time a squarewave generator is used for source 1 in place of a sine source. The frequency of the source is measured by using a differtiating circuit of known frequency dependence for the N.U.T. 2. The network may also comprise inductance or capacitance combined with resistance, Figs. 3, 5 (not shown), whose values can be calculated from the aforementioned parameters. To improve noise response, filters may be added between the amplifier 3 and indicator 4. This output may also be detected and displayed on a D.C. meter, Figs. 6-8 (not shown).

1,236,038. Stop motion. TORAY INDUSTRIES Inc. 3 Dec., 1968 [12 Dec., 1967], No. 57436/68. Headings DID and D1J. A device for stopping spinning in an openend device upon the occurrence of a thick part in the produced yarn comprises a device such as a tube 3c through which individual fibres are carried in an air flow to the chamber 4, a duct 10b whereby compressed air is fed to tube 3c to produce the air flow, an electromagnetic valve 10a in duct 10b and means downstream of chamber 4 to detect a thick part in the yarn and cause valve 10a to be actuated to stop the supply of compressed air and thus halt the spinning process. As shown a slit is provided between plates 9a, 9b spaced so that a thick part is caught and the yarn broken; this allows a biased feeler 8b to swing sideways, and operate a switch which causes valve 10a to be operated. A suction nozzle 21 catches the loose end of yarn and prevents it being drawn back into the spinning chamber by centrifugal force. A second biassed feeler 8c is provided at the exit of the spinning chamber to stop the supply of compressed air should the yarn break or become weak and slack in this region. In Fig. 2 not shown the slit flats (19a, 19b) are inclined to the yarn so that when a thick part engages the slit the yarn is deflected sideways to shift a feeler (8b) and close valve 10a. In Fig. 4 not shown the slit is at one end of a plate pivoted about a horizontal axis. When a thick part engages the slit the plate is pivoted against a biassing spring thus releasing a switch which closes valve (10a).

1,211,052. Wave-energy position finding. FRIED. KRUPP G.m.b.H. 4 Dec., 1968 [5 Dec., 1967], No. 57584/68. Heading H4D. The sound wave emissions from, e.g. a submarine 13 are received at buoys 11, 12 which produces signals representative of angles # 1 , # 3 respectively, the buoys also produce signals representative of angles # 2 , # 4 respectively from sound or radio waves from an aircraft 14, and the signals are transmitted to the aircraft which is flown such that # 1 = # 2 and # 3 = # 4 : the aircraft is then above the submarine. On a buoy, a transducer 21 of the kind described in U.S. Specification 3,290,642 produces voltages representing the sine and cosine components of the bearing and a non-directional voltage, the three voltages are fed to a switch and synchronizer (24, Fig. 2 (not shown)) also fed via a switch (26) and a frequency-changer (25) with voltages representing the sine and cosine of the radio bearing of the aircraft, and a non-directional voltage utilizing a crossed-frame aerial (22) and a non-directional aerial (23). The frequency-changer transforms its input voltages to the frequency range of the transducer, the output voltages of the transducer and the frequency-changer being applied to a common bearing calculator (27) which signals the # values to the aircraft. On a buoy the relating of the bearings to North utilizes a compass-stabilized transformer, Fig. 3 (not shown). Rotation or displacement of the buoys has no effect on the system. The buoys may be dropped by the aircraft which is steered before the release of the second buoy to secure maximum accuracy in position location. The noise from the aircraft may be utilized on a buoy for determining aircraft bearing. The invention may be used to indicate to an aircraft the positions of acoustic responders (which then take the place of submarine 13).

1472548 Thermal regenerators NOEL PENNY TURBINES Ltd 12 Dec 1974 [14 Dec 1973] 58124/73 Heading F4K In a seal assembly for a rotary regenerator 7 including peripheral and cross arm seals located between the end faces of the matrix 7 and a surrounding housing 8 (9, Fig. 2) each seal comprises a backing plate 2, or 4, urged into engagement with the adjacent end face of the matrix by an axially compressible resilient member 1 or 3 the interior of which is in communication with an annular chamber 13 supplied with compressed air and surrounding the matrix. The peripheral and cross arm backing plates 2, and 4, are formed separately so that they can expand independently during heating. Each arcuate backing plate 2, has outwardly extending lugs 20 at its ends which co-operate with a respective end of the cross arm backing plate 4. The distance between the lugs 20 is less than the length of the cross arm backing plate 4, whereby the cross arm backing plate 4 is compressively stressed between the lugs 20 on each arcuate backing plate 2 under cold conditions and the length of the cross arm backing plate 4 is such that the backing plates 2 and 4 are substantially stress-free under hot working conditions. The lugs 20, which have ears 21, are located between inwardly extending circumferentially spaced walls 14 on the housing 8, which walls 14 serve to prevent the seal assembly from rotating in the housing. The arcuate backing plates 2 are made elliptical with the major axis thereof being at right angles to the cross arm backing plate 4 and the ellipticity such that under hot working conditions the plates 2 will become circular. The surfaces of the backing plates 2 and 4 engaging the matrix 7 are formed with respective rubbing layers 6 and 5. As shown the resilient members 1 and 3 of each seal are secured together to provide a continuous surface by bending one side wall of each peripheral member 1 around the adjacent rim portion 10 of the cross arm member 3. Alternatively (Figs. 6 and 7, not shown) the resilient peripheral and cross arm members 1 and 3 may be joined together by welding.

1344659 Lubricator; valves A MATHES 17 Dec 1971 [22 Dec 1970] 58743/71 Headings F2A and F2V A lubricating device which is located in the compressed air conduit of a pneumatic tool comprises an air pressure chamber and a surrounding oil chamber and an opening from the oil chamber to the air chamber which is closed by a valve. In operation air is fed to the air chamber 2 via a connection 14 and flows through a filter 15. The air moves a valve against a spring 18 thereby opening the passage to the tool and uncovering the connection between the air and oil chambers. Oil flows from the oil chamber and is entrained in the flow of air to the tool. The valve has a valve stem which moves in a sleeve 21 which contains the spring 18. On compression of the spring air is expelled from within the sleeve through a non-return valve 9. On stopping of the tool by cessation of the air flow, excess air on the downstream side of the valve flows back past the valve by deflecting a flexible portion 7 of the valve head. The flexible portion is permitted to deflect only in one direction by rigid portions of the head. Air under pressure passes into the oil chamber so that the pressures in the air and oil chambers are equalized. The return of the valve to its initial position is retarded by the low pressure within the sleeve, thereby allowing time for the pressures to become equalized. When the valve resumes its initial position, the oil chamber is closed by a valve cone 6. The oil chamber has a transparent inspection port 13 and a filling plug 12. A filter 17 may be interposed in the passageway between the oil chamber and the air chamber. The sleeve may be provided with a helical groove which receives a cam carried by the valve shaft so as to impart rotational movement to the valve shaft during its longitudinal movement.

1,249,536. Data transmission systems. INTERNATIONAL BUSINESS MACHINES CORP. 8 Dec., 1969 [14 Jan., 1969], No. 59766/69. Heading H4P. In a system having at least two speeds of transmission, each set of data is preceded by at least one character having a determined number of level transitions per unit time which is detected at a receiver and compared sequentially with a number of locally generated signals until the speed is identified. Audio signals on a line 12 are converted to binary signals in a unit 11 and amplified at 14. A clock 20 generates one of a series of frequencies on line 21 which actuate a monostable multivibrator 26 passing pulses to a counter 51, also timing pulses T1-T3, one for each oscillator cycle commencing at the start of each bit interval. Clock 20 is activated by the first signal transition on line 15 the circuit being previously set by a signal on line 29 when the receiver is switched to line which latches circuit 30 and sets counter 31 to zero, also through OR gate 32 sets latch 33 to the rest condition. As the first signal is a zero, input to AND gate 36 is low while the complementary signal from inverter 37 to AND gate 38 is high. A pulse on line 27 will pass through AND 38 to set latch 39 to zero. At the succeeding time T1 the signal on line 22 gates AND 42 to pass the signal if latch 39 is zero and latch 33 is at " ONE " or will gate AND 43 if latches 33, 39 are reversewise. Output of AND gates 42, 43 are combined in OR 44 which provides a signal on line 45 when the states of latches 33, 39 are different, i.e. when there is a data transition. The number of transitions are counted by counter 31. At time T2 after data transitions, if any, have been counted, the state of latch 39 is transferred to latch 33. AND gates 48, 49 receive mark and space outputs of latch 39 when gated by the T2 signal on line 23 transferring the setting of latch 39 into OR gate 32 on the mark or space input to latch 33. To determine the incoming speed pulses on line 27 are counted into counter 51 which are recognized by a decoder 52 when the count reaches 8. AND gate 54 receives a signal from decoder 52, also an output from latch 30, a T2 signal on line 23, and a signal from NOT gate 56, hence generates an output which resets latch 58 which transfers the output from line 59 to line 60 this disconnecting the high speed oscillator and energizing the low speed oscillator hence the process is repeated. At time T3 after counter 51 has reached a count of 8 latch 30 is reset by signal T3 to AND gate 64 which also resets AND gate 54 to prevent consequent functioning of latch 58. Or gates 57, 61 can be activated to select an oscillator for other functions (not disclosed). A greater number of oscillators than two may be provided and switched in sequence.

1360480 Superconductor devices COMPAGNIE GENERALE D'ELECTRICITE 23 Dec 1971 [7 Jan 1971] 60085/71 Heading H1K A superconductor switch comprises a superconductive-winding and a control winding wound coaxially in which the number of superimposed turns in one of the windings increases from one end to the other. This enables the superconductive load winding to be switched from its superconductive state to its normal state according to a desired time dependent law. The switch is utilized to control the charging, storage and discharging of a superconductive storage winding. As shown, Fig. 1, a cylindrical superconductive load winding 1 is provided with two tapered control windings 4, 5. When energized the control winding produces a magnetic field which is larger at one end than at the other so that as the control current increases the load winding is progressively switched to the normal state, its resistance increasing according to a law which depends on the distribution of turns in the tapered winding and on the waveform of the energizing current. In a second embodiment, Fig. 3 (not shown), the load winding is tapered and the control windings are uniform. In a further embodiment, Fig. 4 (not shown), all of the load and control windings are tapered. The load winding may comprise turns of multi-strand Nb 40% Ti or Nb-Zr alloy or single wires or tapes of Nb 3 Sn. The control windings are of Cu and the switch is enclosed in a magnetic screen 6, e.g. of Cu.

1,208,500. Endless conveyers; packaging glass tubes. CORNING GLASS WORKS. 18 Dec., 1968 [26 Dec., 1967], No. 60168/68. Headings B8A and B8C. [Also in Divisions F2 and G1] Apparatus for automatically inspecting, sorting and packaging glass tubes 10 comprises conveyers 12, 18 which advance the tubes to star wheels 20 at each end of the tubes. The star wheels deliver the tubes to chucks 24 which grip the tubes whilst gauging devices examine the ends of the tubes. Satisfactory tubes drop from the chuck between guides 50, 52 on to a supply rail 44 where they are moved by conveyers 116, 48 to a stacker supply shelf 120. Unsatisfactory tubes cause the gauge to supply a signal to the guides 50 which move towards the guides 52 thereby causing the rejected tubes to be delivered to a conveyer 56. A by-pass gate 16 may be operated to direct the tubes directly from the conveyer 12 to the conveyer 56 via a conveyer 27. Three switches (118), Fig. 13 (not shown), are located above the rail 44 so that if a build up of tubes occurs, thus causing each of the switches to be simultaneously actuated, a signal is transmitted to the guides 50 to divert following tubes to the reject conveyer 56. The conveyer 48 has spring loaded pegs 46 so that in the event of a tube build up the pegs pass over the tubes. Eight jigs 122 are intermittently advanced by a chain 124 to the shelf 120 where they are automatically filled with seven rows of nine tubes. The jigs then advance to a capping station where end caps 136 are placed on the ends of the stack of tubes. The end caps are stored on four horizontal guide rails 138 and are advanced singly by a cylinder 150 having suction cups 152. A photo-cell 146 detects the presence of a cap to prevent further forward movement of the supply of end caps by a motor 142. The cylinder 150 is longitudinally movable and is rotated about an axis 154 so that the caps, which have four flaps supported by arms 156, are placed on the ends of the stack of tubes. End cap brackets 158 are lowered around each end cap to maintain the caps on the stacks before the bundles reach a station where they are tied with string. After tieing, the bundle is ejected by a bundle ejector to a conveyer 166.

690,964. Synchronous machines. HACKBRIDGE & HEWITTIC ELECTRIC CO., Ltd., and WELLS, R. Jan. 2, 1952 [Jan. 3, 1951], No. 229/51. Class 35. [Also in Group XXXVII] A synchronous motor 10 of the non-salient pole type has its D.C. winding 13 supplied through a grid-controlled rectifier 18 from an auxiliary alternator 21 which is driven by the motor, the grids of the rectifier being supplied from the main A.C. source 12 through a phaseshifter 23. When a change-over switch 16 is moved to the starting position the winding 13 is connected to rheostat 15 and the negative and positive terminals of a grid bias unit 24, which comprises a rectifier and a mainsconnected transformer, are joined respectively to the cathode 17 and to the star-point of the phase-shifter. The motor thus starts as a wound rotor induction motor, the rectifier 18 being independent of the relative phasing of the anode and grid voltages whereby the rectifier is able to provide a maximum current when it is switched into the motor excitation circuit. The actuation of the switch 16 to its other position connects the cathode 17 to the phaseshifter 23 and also to the rheostat 15, so that the unit 24 is rendered inoperative and the rectifier 18 supplies the winding 13 for synchronous running. If the load angle of the motor increases the phase position of the anodes of the rectifier 18 is retarded with relation to the constant grid phase position, so providing a compensating increase of motor excitation. When the motor is of the salient-pole type, Fig. 4 (not shown), the excitation of the D.C. winding is provided by a separate source after the motor has been started and until synchronism is attained, whereupon the gridcontrolled rectifier is substituted for the separate source.

Circuit breaker anti-rebound latch
|
en
|
A circuit breaker has an anti- rebound latch 105 comprising a single resilient member which engages a protrusion 101 on a toggle link 44 to block contact-reclosing movement of the toggle unless a releasable cradle 55 (shown tripped) is in its reset position. The latch 105 is mounted in a fixed position within the circuit breaker and is deflected by the protrusion 101 during a tripping operation to permit collapse of the toggle. Resetting of the cradle lifts the protrusion 101 clear of the latch 105 to permit the toggle to be extended and thus move contact arm 35 into the closed position. The mounting aperture for contact arm pivot 42 is elongated to counteract contact welding. <IMAGE>

Hydraulic Actuator
|
en
|
A hydraulically operated actuator has a hydraulically driven piston 30 slidable in a chamber 31, the movement of the piston 30 being converted into rotary movement of a shaft 40 by an assembly 33, 43, 44, 50, 51 which limits the torque placed on the shaft by the piston in its drive stroke. The torque is limited since a non-rotatable axially movable member 43 with pins 51 riding in helical slots 50 in the rotary shaft is displaced by the piston 30 through the intermediary of a spring 44. A return spring 52 enables the piston 30 and drive spring 44 to return to their initial positions upon release of the hydraulic supply pressure applied to the piston through a port 85. A static seal 30a on the piston seals against an end wall 31a at the completion of the drive stroke of the piston. The actuator may be used to operate a subsea diverter to direct "pump down" or through flow line (TFL tools) through wye- branched flow passageways formed in a diverter body member located on a submerged well head. <IMAGE>

Improvements in paper and other sheet material roll dispenser
|
en
|
A holder for toilet or like rolls which is capable of containing at least one reserve roll which can be quickly transferred to an in-use position once a roll in use becomes exhausted. The holder includes a housing having an aperture through which the toilet paper can be dispensed. That aperture has a size such that an empty or nearly empty roll can pass through it but a full roll cannot. A pair of levers are pivotted to the sides of the housing and they each carry tapered supporting bosses for supporting a roll in use and retaining ledges on which a fresh roll can rest clear of the roll in use. When the levers are moved outwardly to a cycling position, the roll in use is released and can be discharged through the aperture if sufficiently depleted and then a fresh roll can drop to a position to be picked up by the bosses when the levers return to their normal position. The base of the housing is inclined to bias an empty roll released by the supporting means towards the aperture.

The outputs Ux, Uy of the camera 10 are fed respectively to one input of corresponding high gain differential amplifiers 11 and 12 whose outputs V and W are applied to corresponding inputs of a quadripole non-linear device 13 (Figure 4 not shown) as orthogonal deflection signals for a cathode ray tube. The location of a spot deflected thereby is sensed by an assembly of photodetectors 23 having the same distribution relative to the cathode ray tube screen as the photomultipliers of the camera 10 relative to the scintillation crystal. A weighting circuit 24 generates output signals Uv and Uw representing the barycentre of the photodetector outputs, which are fed to the respective other inputs of the differential amplifiers 11 and 12, thus completing a servo feedback loop. When the servo loop reaches an equilibrium state, the signals V and W provide corrected output coordinate values linearly related to x and y. <IMAGE>

Foamed plastics slabs
|
en
|
A pressurized melt of synthetic thermoplastic material containing a volatile expanding agent is continuously injected axially and expanded into the inlet end 43 of an open-ended tubular duct formed by a plurality of separate, externally cooled longitudinal walls A18', B18', C18', D18' in mutual sealing contact along the generatrices of the duct. The foam completely fills the cross-section of the duct while the walls are advanced jointly at a speed equal to the rate of growth of the foamed slab being formed and accompany the latter until the slab is stably set. Conveniently, the walls each consist of a working run of an endless belt conveyor. <IMAGE>

Clasp structure for wrist watch band
|
en
|
A clasp structure for a wrist watch band having a pair of links (20a, 20b) comprises a fastening member (24) secured to strap (20a) and an engaging member (26) secured to strap-end (20b) and having first and second engaging claws (40a, 46a). The fastening member comprises a clamping lever (36) rotatably supported by a transverse pin (32) also serving as a snap-fastening for the claw (40a) which locks the fastening, this clamping lever having first and second cutout holes (36d, 36e, 36f). This first engaging claw (40a) passes through first cutout means (36d, 36e) and engages with the pin (32), and the second engaging claw (46a), which is actually hooked into position first, engages with a marginal portion (36g) of the second cutout means, so that the engaging member (26) is fixedly coupled to the fastening member 24 thereby to interconnect the links together. <IMAGE>
