Process for the preparation of epsilon-caprolactam
|
en
|
e -Caprolactam is prepared by heating at least one of the compounds e - caprolactone, e -hydroxycaproamide and amide forming derivatives of e -hydroxycaproic acid, in aqueous ammonia, in an atmosphere comprising free hydrogen to a temperature within the range 200-420 DEG C., under a pressure at least sufficient to maintain a liquid phase in the reaction zone. Suitable derivatives of e -hydroxycaproic acid are its alkyl, cycloalkyl, aralkyl and aryl esters, or its ammonium and alkali metal salts. The reaction may be carried out in an atmosphere of hydrogen alone, or hydrogen mixed with other inert gases, e.g. nitrogen and helium. In this case the partial pressure of hydrogen is advantageously 0.01-100 atms. The preferred concentration of ammonia is 0.1-35% by weight, and the preferred mol. ratio of caproic acid derivative starting material to aqueous ammonia (in terms of pure ammonia) ranges from 1:1 to 1:25. The lactam is isolated from the aqueous ammonia solution of lactam produced and after the extraction the residue may be recycled.

589,896. Wringers. CO-OPERATIVE WHOLESALE SOCIETY, Ltd., and MOORE, J. R. March 30, 1945, No. 8091. [Class 138 (ii)] The drip tray of a wringer is in the form of a single fitting having upper and lower walls 2, 1 projecting from either side of the rollers. The fitting is rockable between two positions in which either upper wall 2 is inclined or horizontal, so that the machine can be used from either side; when inclined the upper wall keeps articles fed to the rollers clear of drain water passing away to a drain hole 4 at the outer edge of the lower wall, whilst when horizontal it lies adjacent the lower roller just below the nip and serves. as a mangling board. In Fig. 1 the fitting is formed from a metal strip, folded over at its two ends to form the upper walls, and secured to end plates 5. The latter have inverted T-slots 10 by which they are engaged over the journals of the lower roller, and which limit the rocking movement about pivots 7. The upper walls 2 may, alternatively, be removable to facilitate cleaning the interior of the fitting. In Fig. 2 the upper walls are formed as separate parts 15, 16 secured to a lower tray part 14. The upper parts have inturned lugs 20 to engage the lower roller or its journal, or, as shown, ribs 21 formed on the side frames. This constitutes the pivotal mounting of the fitting, movement being limited by T-slots 23 in the side frames in which pins 22 on the fitting work. Specification 523,273 is referred to.

Improvements in or relating to electric pulse signalling systems

693,862. Multiplex pulse code signalling. GENERAL ELECTRIC CO., Ltd., and STENNING, L. C. Feb. 13, 1952 [April 9, 1951], No. 8243/51. Class 40 (v). In a pulse signalling system, phasing of the receiver equipment is determined by a received pulse train having a characteristic modulation and at least three monitoring means, to which are fed pulse signals occurring in adjacent pulse intervals, and which produce outputs from the characteristic signal which provide phase correction voltages unless the signal is fed to a predetermined monitor circuit. In the system described, there are twelve five-unit binary on-off code channels, the channel recurrence frequency being 8 kc/s. so that pulse positions recur at the rate of 480 kc/s. The last pulse positions of the groups of one channel are utilized to carry pulses defining a characteristic modulation. At these positions there is alternately a pulse and no pulse so that the pulses defining the characteristic modulation have a recurrence frequency of 4 kc/s. For this purpose, at the transmitter the coder 1, Fig. 1, feeds the output terminal 4 through a gate circuit 2, which suppresses any pulses occurring in every sixtieth pulse position, that is the fifth and last pulse position in one of the twelve channels. The gate circuit 2 is controlled by a pulse generator 3 which also supplies pulses to the output terminal 4 having a recurrence frequency of 4 kc/s. so phased that they occur at alternate time positions when the gate circuit 2 is non-conducting. At the receiver, the pulse code signal from terminal 11, Fig. 2, is fed to the decoder 12, the operation of which is determined by the phase of oscillations supplied, through a variable phase-shifter 13, by an oscillator 14. The frequency of oscillator 14 is controlled by the code signal from terminal 11. Five monitors, 15... 19, are responsive to pulses having the characteristic modulation and are supplied with pulses from the signal occurring at every sixtieth position, the monitors being supplied with such pulses derived from a group of five adjacent pulse positions. For this purpose terminal 11, and four tappings on a delay line 21 fed therefrom are connected respectively to the five gate circuits 22 ... 26, the tappings being spaced by a period equal to that between adjacent pulse positions. A common gating signal is fed to the gate circuits from the pulse generator 27, which is controlled by the oscillator 14 and phase-shifter 13, so that the gates pass the signal component occurring at every sixtieth pulse position. Taking the monitor 17 for example, the signal from gate 24 is passed through a band-pass filter 28, adapted to pass oscillations of 4 kc/s. frequency, to an amplifier 29 and rectifier 31, controlling relay C. The relay C is operated if the gate 24 is passing the pulses having the characteristic modulation. Similarly relay A, B, D or E in monitor 15, 16, 18 or 19 respectively, is operated if gate 22, 23, 25 or 26 respectively is passing these pulses. For normal operation, the receiver is arranged to require the relay C to be operated by the characteristic signal in order correctly to phase the decoder 12. This opens contacts C<SP>1</SP>, C2 to cut off the supply to relays F, G, which control the supply, and its polarity, to a motor 33 provided to operate the phaseshifter 13. If, when the phasing is incorrect, relays A or B are operated, contacts A<SP>1</SP> or B<SP>1</SP> are closed to energize relay F which cuts off the supply to relay G at contact F<SP>2</SP> and energizes the motor 33 at contact F<SP>1</SP> for one direction of rotation. The resulting adjustment of the phase-shifter 13 is such as to alter the phase of oscillations supplied to the decoder 12 and pulse generator 27 towards the desired condition when the pulses having the characteristic modulation are applied to the monitor 17 to operate relay C. If relays D or E are operated, due to incorrect phasing, the motor 33 is energized at contact G<SP>1</SP> to rotate in the opposite direction, by energization of relay G through contact D<SP>1</SP> or E<SP>1</SP>. At the same time, the circuit of relay F is broken at contact G<SP>2</SP>. While adjustment is taking place, instants may occur when none of the relays A ... E is operated, so that a holding circuit for relays F and G is provided through contacts 34, 35 which are closed while the phaseshifter 13 is being operated. Energization of relay C subsequently, will de-energize motor 33 and open contacts 34, 35. Automatic phasing is thus accomplished if the received signal slips one or two pulse positions either forward or backward. For the initial setting up of the receiver, a timing signal, as described in Specification 693,859, may be transmitted thereto. If a slip of more than two positions has occurred, an alarm signal may be automatically produced, for transmission back to the transmitter, and operated by a circuit containing additional series-connected normally-closed contacts of the relays A ... E. Instead of using the fifth pulse position in every group of one channel, that position may be used only in every fourth group, for example, to reduce the degradation of the intelligence transmitted over the channel. If the invention is applied to a pulse time modulation system, the transmitted signal also contains periodically recurring pulses having a characteristic modulation.

299,256. Krupp Akt.-Ges., F. Dec. 1, 1927, [Convention date]. Addition to 286,639. Tip-wagons; hopper wagons. -The dumping wagon described in the parent Specification is modified in that, for effecting the tipping and return movements of the body A by means of the compressed air gear, the curved member which cooperates with an actuating member on the piston-rod is replaced by a two-armed lever D, Fig. 1, one arm d<1> of which coacts with a lug c<3> on the piston-rod c<1> during the tipping movement, while the other arm d<2> coacts with the lug during the return movement. The piston rod c<1> has at its upper end a slot c<2> engaged with lost motion by a detachable pin a<4> on the body. During the first part of the movement of the rod c<1> the pin a<4> passes from the upper to the lower part of the slot c<2>, while the lug c<3> displaces the arm d<1> of the lever D, which is keyed to the rotary operating-shaft a<2>, and so unlocks the toggle b<2>, a<1> against the influence of a tension spring K. At the end of the discharging movement, Fig. 4, the arm d<2> engages the lug c<3> to prevent overthrow of the toggle, and also to be in readiness for rotating the shaft a<2> in the reverse direction during the return movement of the body. When the discharge is to be effected by the hand gear, the pin a<4> is removed so as entirely to disconnect the compressed air gear, and the tipping is carried out as in the parent Specification by means of a loose sleeve E, which is operated by a handlever F and carries a double pawl G co-operating with a ratchet wheel H on the shaft a<2>.

1,066,904. Blasting. TILGHMAN WHEELABRATOR Ltd. Feb. 24, 1966 [March 1, 1965], No.8615/65. Heading B3D. Metal articles are blasted, e.g. to produce a fine or semi-polished finish, by a stream of abrasive metallic powder having a maximum particle size of less than 84 B.S. mesh and a minimum particle size of 200 B.S. mesh. Suitable metal powders include iron, steel, stainless steel, brass, copper, zinc and aluminium. The blast may be produced by an impellor wheel or by air. The powder is preferably of the same material as the metal article being treated so as to avoid contamination of the article with foreign material, this being important when treating containers for food or drink, e.g. stainless steel beer barrels. By varying the shape, hardness and composition of the particles various shades of the colour of the metal article can be produced; stencils may be used to produce a decorative effect. A base material may be plated with one or more metal coatings which are at least partially cut through by blasting to expose the colour of the coatings in a pattern.

In a low pressure liquid moderated, liquid cooled reactor, the moderator is thermally shielded from the coolant to maintain its vapour pressure low. The fuel elements are mounted in vertical ducts through which the coolant such as lead or sodium flows. The ducts are provided with surrounding jackets through which a gas such as argon or helium is circulated to maintain the temperature of the jacket outer walls low to prevent the transfer of heat to the liquid moderator. Power control is effected by control of the moderator level. Leaks in the ducts or jackets are detected monitoring the coolant and moderator spectrographically for the presence of the jacket gas.

1,215,805. Tyre fitting and removal tool. DUNLOP CO. Ltd. 23 Feb., 1968 [23 Feb., 1967], No. 8666/67. Heading B7C. A tyre fitting and removal tool, see Fig. 1, for mounting upon apparatus on which a wheel is releasably secured in a stationary or rotatable manner comprises a plate 10 having a fitting element 17 and guide 18 located at one end and a removal element 20 located at the other end. In use, see Fig. 4, the tool 7 may be mounted on a shaft 14 having a frame 15 which may be secured to an arm 9 integral with shaft 6. To fit a tyre to a wheel clamped on the apparatus, the tool 7 is positioned so that the guide and removal elements 18, 20 abut against the radially outer surface of the uppermost rim flange 22. The tyre is then placed on the wheel so that its lower bead is partly over the rim and partly in contact with element 17. On rotation of the tool, the lower bead passes over the rim into the well 23 of the wheel. The upper bead is then placed partly over the rim and the operation is repeated. Alternatively, both beads of the tyre may be placed partly over the rim and the tool operated in the manner described. To remove the tyre from the wheel, a tyre lever is placed under the upper bead to lift it on to surface 21 of the tool. Rotation of the tool about the wheel then causes element 20 to lift the bead out of the wheel well. The lower bead may then be removed in a similar manner. In a modified construction, surface 21, see Fig. 1, may be provided with a protuberance opposite removal element 20. To remove a tyre from a wheel part of the bead is lifted over this protuberance by a tyre lever, which is retained there during the subsequent part of the removal operation. In an alternative type of fitting and removal apparatus, Fig. 5 (not shown), the wheel is rotatably mounted upon a chuck and the tyre fitting and removal tool is held stationary.

985,649. Injection moulding machines. F. STUBBE. March 3, 1964 [April 19, 1963], No. 8829/64. Heading B5A. In an injection moulding machine having an open injection nozzle 10 and an axially reciprocable worm 3, a back pressure is applied to the worm 3 during its retraction stroke and this pressure is released at the end of the retraction stroke to prevent loss of material through the nozzle when the mould 11 is opened. The back pressure is produced by a needle valve 14 connected to a cylinder 6 having a piston 7 connected to the worm 3. When the worm 3 has moved to the right, a limit switch 15 energizes a device 17 to open the valve 14. The switch 15 also energizes a delay timer 16 whereby after a suitable interval a valve 20 admits hydraulic fluid to the cylinder 6 so that the piston 7 is moved further to the right and the worm 3 sucks back material from the nozzle 10.

The angular velocity in a device 12 comprising a first rotatable mass M is kept constant by coupling it, through a cyclically varying velocity ratio transmission such as the meshing eccentric gears 10, 11 and a torsionally resilient coupling D, with a second rotating mass M2. As the resonant frequency of the system is approached, by excitation through the transmission, a resultant power loss sets up a velocity control barrier causing the regulation. The invention is applicable especially to time measuring mechanisms, in which the device 12 includes a spring driving motor. A smooth output motion over small time increments is obtained, as contrasted with escapement controlled mechanisms. Also, the mechanism is unaffected in spin stabilized environments such as in ordnance projectiles. Fig. 18 illustrates the run-down 22 of the spring motor in a non-elastic system, compared with the regulation 20 in the system described using a relatively light aluminium mass M2, and 21 using a heavier steel mass M2.

Figs. 1 to 4 show finder switches, selectors witches and battery feed equipment. The remaining figures show control equipment. Each line appears in the same position in five finderfinals PFF, . . . TFF (QFF and SFF, not shown) which are so connected to two 100- point secondary finders F2U, F2V that each line has single access to each of 20 secondary outlets or routes marked by suffixes Pp-Ps, Qp-Qs ... Tp-Ts. The routes, which are identified by battery feed equipment such as PpBF, are connected both to registers REG1- REG4 and to inlets of the first digit selectors DIU, DIV, each inlet having single access to each line. Registration of calling line digits and connection of line to register. When a call is made from line 11 to line 00, a free register BEG1, Figs. 11 to 15 is seized by operation of relay RA over line and cut-off relay contacts 11l1, 11co1 Fig. 5. Four register relays RA, 2RA to 14RA (only RA is shown) are controlled by register release relays 1B to 4B, Fig. 10, so that only the first free register is seized. Registers are connected to different line groups in a different order of preference. Control relays RA, RB, RC, and possibly RD, operate and release in turn. When RA operates, select magnet 1PM operates over contacts 11l2, 11co2 marking the tens digit 1 of the calling line and hold magnet HA registers the digit. The prepare magnets 1PM to 0PM hold over chain contacts 1pm2-0pm2 so that only one can fully operate if more than one is energized. Relay RA and the prepare magnet 1PM release and RB operates followed by hold magnet HB to register the unit digit 1 of the calling line marked over contacts 11co3, 11l4, Fig. 6. Relay RC completes test circuits for finding a free route to the register, the circuits being shown again in the left-hand section of Fig. 18. Only the first ten routes Pp-Ps Qp-Qs Rp-Rq are tested with RC operated. If one or more routes are free, only one prepare magnet say 1PM, operates fully, as previously described, and hold magnet HC then follows. Finder-final PFF is marked busy by relay TCOP, Fig. 7, which operates in series with SF, Fig. 13, and circuits are completed by hold magnet HC to operate prepare magnets 1PFF, 1F2U over contacts controlled by hold magnets HB, HA and to operate hold magnet HF2Pp. Hold magnet HIP is operated over contact 1hf2PpC in the secondary finder and the line 11 is extended to relay A, Fig. 13, cut-off relay 11CO being operated over h1P2 Dial tone is fed to the line from the generator DTT. If there is no free route in the first ten, relay X operates over the chain contacts 1pm2-Opm2 of the unoperated prepare magnets, control relay RD operates and RC releases. The second ten routes are tested in the same way as the first ten and the line 11 is extended to relay A as before if a free route is found. If no free route is found, relay Y operates over the chain contacts 1pm2 to Opm2 and at contact y1, Fig. 12, releases the hold magnets HA-HD. The register returns to normal, but if line 11 is still calling, the operation is repeated until a free route is available. It will be noted that both relays RC, RD are operated over chain contacts so that only one of the four registers can test at any time. Relay RCX or RDX disconnects the locking earth from the chain circuit when relay RC or RD operates. One register may test the first ten routes whilst another tests the second ten. Registration of called line digits. Relay 1, Fig. 13, operates and responds to the impulses dialled. Relay B, Fig. 10, operates with A and remains operated until the register is released. Relay CA is a dialling relay. The impulses repeated by A are counted by relay pairs 1A, 1B to 4A, 4B, an A relay operating at the beginning of each impulse and a B relay at the end. They respond to 10 impulses in the order 1B, 2B, 3B, 4B (followed by 4C) 1B, 2B, 3B (followed by 3C) 1B, 2B (followed by 2C) 1B. At the end of a digit, ground is connected to a tree of marking contacts over contacts ca4, cb3 between the relapse of CA and the relapse of CB. The marking conductors 1-0 are connected to the magnets 1PM-0PM and the select magnet corresponding to the dialled digit operates. The digits are counted by relay pairs IDA, 1DB; 2DA, 2DB. When the tens digit is received and a select magnet operates, hold magnet HE follows over contact 1db2 to register the digit. When the unite digit is received, hold magnet HF follows over contact 2db3. Hold magnet HF closes a circuit for relay IR (Fig. 10) Which is followed by Z, Fig. 11, and starts a test for a route between the calling and the calling lines by operating RC and RG together. A through test is now made over the first ten routes shown on both sides of Fig. 18 and if a route is avail able, a select magnet operates. Hold magnet HG follows over contact rg15. If the register has been seized over route Rq and the first available route is Pp, select magnet 1PM operates and is followed by hold magnet HG Relay ST operates with TCOR which marks busy the finder PFF through which the route Pq has access to the calling line. The register is released when relay B falls back after a delay Relay TCOQ operates to mark busy the final selector in which route Pp has access to the wanted line. Circuits are completed over contacts 1hgC, 1hgE respectively to operate select magnets 1PFF for the calling line 11 and 0QFF (not shown) for the called line 00, to operate relay HR in the battery feed circuit RqBF, Fig. 3, and to operate hold magnet HDIPp which locks to hr1. The secondary finder select magnet IF2U and the digit selector magnet OD1U are operated by ground on contact x4, Fig. 14, and register crossbar contacts corresponding to the tens digits 1 and 0 of the calling and the called lines. When ground is connected at hr1, hold magnet HF2Pp follows in the secondary finder and hold magnet HOQ (not shown), follows in the final selector. Hold magnet HIP is operated over crossbar contact lhf2PpC. The line is extended over contacts hr2, hr3 to the relay CLR which operates and feeds battery to the calling line. Ring-back tone is fed to the calling line from a generator BT through the lower winding of CLR. Ring current is fed to the called line from generator RN through a ring trip relay RTR which operates when the call is answered. Battery is fed to the called line through relay WLR. The connection is held over contact hr1. If the first ten routes are busy, relay X operates as before and relays RD, RH operate together to test the second ten routes. If there is no route available when the second set of ten routes is tested, relay Y operates and is followed by HR and busy tone is fed to the calling line. If the line is busy, before route testing starts, relay BR, Fig. 14, operates over one of the line and cut-off relay contacts 00co6, 00l6 and is followed by relays Y, HR. The register is released and busy tone is returned to the calling line. If the register is seized over route Pp, that route will be the first route available for the connection. To enable Pp to be selected, the test contacts h1P1, hf2Pp1 opened by the register connection are shortcircuited over contact rgll (Figs. 13, 18). Specifications 652,881, 656,559, 744,122 and 744,129 are referred to. Reference has been directed by the Comptroller to Specification 679,544.

1,059,752. Automatic speed control. EATON YALE & TOWNE Inc. March 3, 1965 [March 5, 1964], No.9141/65. Heading G3R. In a control system for a coupling having field coil FC, interrupter CI is driven by the output shaft to develop square-wave voltage pulses across resistor 47, the pulse-frequency being proportional to shaft-speed. A network 47, 49, differentiates the square wave, and a diode 51 clips the positive-going peaks. The triangular pulses so formed are integrated by network 53, 55, 57, to form a pulsating D. C. signal whose average potential level is proportional to shaft-speed. This signal is applied to transistor T1 in parallel opposition to a D. C. reference voltage derived from potentiometer 39. A power transistor T2 acts in push-pull relationship with the transistor T1 to control the average power supplied to the coil FC. A positive feedback path is provided from the collector of transistor T2 to the base of transistor T1. In another arrangement, a differential transistor amplifier is connected between the integrating network and the control element of transistor T1, the output of this amplifier being a function of the deviation between the actual and desired speeds of the shaft. The pulsating D. C. signal and the reference signal may be derived from a common source so that load-induced voltage changes are compensated for.

Process for preparing 2-chloro-3,5-dialkoxy-phenols
|
en
|
2 - chloro - 3,5 - dialkoxy - phenols are prepared by heating the corresponding 3,5 - dialkoxy - phenols with N - chlorosuccinimide, preferably in an inert solvent and at temperatures in the range of 35 to 75 DEG C. Preferred 3,5-dialkoxy-phenols are those containing low molecular weight alkoxy radicals, especially methoxy, ethoxy or propoxy radicals. The preferred inert solvent is carbon tetrachloride. The crude product obtained from the reaction contains small quantities (1-4%) of the isomeric 4-chloro-compounds, and this is removed during the purification of the product by vacuum distillation. Two examples are given, illustrating the preparation of 2-chloro-3,5-dimethoxy-phenol and 2-chloro-3,5-diethoxyphenol.

Improvements in and relating to the manufacture of amidines
|
en
|
Amidines, or salts thereof, wherein one or more of the hydrogen atoms attached to the nitrogen atoms of the amidine group are substituted by an alkyl, aralkyl, aryl or heterocyclic group, are obtained by heating an acyl sulphonamide of general formula XCO.NR.SO2.Y, where X.CO represents a carboxylic acid residue, Y.SO2 is an organic sulphonic acid residue and R is an alkyl, aralkyl, aryl or heterocyclic group, with a salt of ammonia or an amine which is not decomposed under the conditions of reaction, e.g. a hydrochloride, sulphate or benzenesulphonate; such amine salts are those of amines of the type NH.R1R2, wherein R1 represents H, or an alkyl, aralkyl, aryl or heterocyclic group and R2 represents an alkyl, aralkyl or aryl group, or R1, R2 together form the two ends of an alkylene chain. The acyl sulphonamides used as starting materials are obtained by acylating an N-alkyl, -aralkyl, -aryl or -heterocyclic sulphonamide. In examples, substituted amidines or salts thereof are obtained by heating together the reactants. Numerous examples are given. N-Acetylbenzenesulphonmethylamide is prepared by refluxing acetyl chloride with benzenesulphonmethylamide in dry pyridine. N-Benzoylbenzenesulphonmethylamide and N-benzoyltoluene-p-sulphonethylamide are prepared by refluxing benzenesulphonmethylamide or toluene - p - sulphonethylamide with benzoyl chloride and dry pyridine. N-Benzoyl-2-benzenesulphonamidopyridine is obtained by treating 2-benzenesulphonamidopyridine in methanolic potassium hydroxide with isopropyl alcohol, suspending the resultant dried potassium salt of 2-benzenesulphonamidopyridine in benzene, adding benzoyl chloride and heating under reflux.

584,937. Control systems for resistance welding. BATEMAN, J. R. May 19, 1944, No. 9704. [Class 38 (iv)] A welding machine has electromagnetic means 40 to maintain electrode pressure independently of a foot pedal or the like and welding current cannot commence until this means is effective, a relay 42, sensitive to current in coil 40, controlling the welding contactor. To forge the weld, release of the pressure is delayed for a timed period after cessation of welding current, the period of application of which is separately timed. As applied to a control system according to Specification 550,615, a switch 1 is closed when electrode pressure is applied to prepare the circuit of contactor 3, 4. A manual switch 39 energizes the coil 40. These two circuits may be supplied by rectified current from a winding S2 and pass respectively through contacts 6 and 46 of relay 7. After the current in coil 40 has become sufficient to lock the pressure means, relay 42 operates and contactor 4 closes to start welding, whereupon relay 14 actuates its contact 53 and coil 40 becomes independent of relay 7 which after the discharge of the weld timing condenser actuates its contacts 6 and 49 to cause respectively contactor 4 to open and to discharge a condenser 35 through contacts 23 and 51, to maintain energization of relay 14 for a period determined by a variable resistance 43. When relay 14 finally releases, its contact 53 de-energizes coil 40 and electrode pressure is released. A manual switch 41 may be used to release the electrodes and cut off welding current at any time.

Denture
|
en
|
Dentures of artificial resin are provided with a soft lining by applying thereto a soft, resilient plastic plate or foil, which has been swollen in a monomeric, polymerizable vinyl compound, and polymerizing the swollen compounds by heat and pressure in the presence of a catalyst. The plates or foils may be copolymers derived from vinyl components which normally yield hard plastics, e.g. methyl methacrylate and at least one other vinyl component which yields soft plastics, e.g. ethyl acrylate, butyl acrylate, hexyl acrylate, octyl acrylate, isobutyl methacrylate, isohexyl methacrylate, octyl methacrylate and n-lauryl methacrylate. It is advantageous to use foils prepared from cross-linked copolymers such as are obtained by complementary use of polyfunctional vinyl compounds, e.g. divinyl benzene, glycol diacrylate, glycol dimethacrylate, butanediol dimethacrylate and hexanediol dimethacrylate. The swelling compound is preferably the same monomer or mixture as that used for making the resilient foil but others may be used, examples being methyl methacrylate, ethyl methacrylate, butyl methacrylate, isohexyl methacrylate, methyl acrylate, ethyl acrylate, butyl acrylate and octyl acrylate. Particularly good adhesion with a polymethyl methacrylate denture is obtained by swelling with methyl methacrylate, butyl methacrylate, isobutyl methacrylate, isohexyl methacrylate and mixtures of methyl methacrylate and acrylates containing more than 50 per cent. methyl methacrylate. Polymerization catalysts may be dissolved in the swelling compound or a second foil, superficially impregnated with the catalyst, may be placed over the plate or foil to be swollen. Suitable catalysts include benzoyl peroxide, p-chlorobenzoyl peroxide and cumene hydroperoxide. Known redox systems, such as those using trihexyl amine or p-toluene sulphinic acid are also suitable, and in this case it is advantageous to incorporate the oxidation agent in the plate and the reducing agent in the swelling monomer.ALSO:Dentures of artificial resin are provided with a soft lining by applying thereto a soft, resilient plastic plate, which has been swelled in a monomeric polymerizable vinyl compound, and polymerizing the swelled compounds by applying heat and pressure in the presence of a catalyst. Various examples of suitable materials are given (see Group IV(a)).

[Class 100 (i).] A method of joining a reserve web to the expiring web of a rotary printing or other webusing machine consists in pressing the two webs together and positioning a thin flexible sheet coated with an adhesive against one of the webs so as to lie between the expiring web and the leading end of the reserve web. In one form of apparatus, Fig. 1, the active roll A and reserve rolls B, C are mounted on chucks 4 rotatable in arms 1 fixed to a shaft 3 rotatable in a stand 2. When a join is to be effected, the expiring web 5 is pressed, by means of a rubber-covered roller 6 carried by a hand-lever 7, against the roll B to cause this roll to rotate, after which a series of side-by-side rollers 10, carrying flexible sheets coated on both sides with an adhesive, is brought into contact with the leading end E of the reserve web to transfer the sheets thereto. The continued rotation of the roll causes the webs to adhere together, after which the web 5 is severed. The arms 1 are then turned to bring the roll B into the running position. The rollers 10 are provided with friction strips 11 of rubber, to facilitate the initiation of their rotation by contact with the roll B, and are freely mounted on shafts 52 carried by arms 12 loose upon a shaft 13 to which are secured collars 16, Fig. 3, carrying pins 17 normally engaging projections 18 on the arms 12 to hold the rollers clear of the roll B. An arm 23 fixed to the shaft 13 is connected by a link 24 to a weighted handlever 25 loose upon the shaft 3 and normally held raised by a pawl 30 engaging ratchet teeth 32 on the lever. Release of the pawl allows the lever 25 to drop thereby turning the shaft 13 and, through the medium of coiled springs thereon, pressing the rollers 10 against the roll B, and the release of the pawl is timed to ensure application of the adhesive sheet to the leading end E of the reserve web. This timing mechanism comprises a cam 36 fixed to the chuck 4 and adapted, by engagement with a pin 35<1>, pressed into its path by the operator, to turn a lever 34 provided with a projection 37 which depresses the tail 38 of the pawl 30. In a modification, the rollers 10 are in the form of spaced discs and the adhesive sheets are temporarily held thereon by pointed wires carried by some of the discs. In a further modification, Fig. 8, the reserve roll is brought into rotation by an electric motor 107 mounted on the arm 1 and adapted to drive the chuck 4 through gears 108, 109, pawl 110, and ratchet wheel 111. Each roll is provided with a motor 107 the leads 115 of which are connected to segments of slip rings 114 on an insulating sleeve 112 fixed to the shaft 3. The segment corresponding to the roll B in pasting position is connected to the mains 155, Fig. 10, by brushes 116 through a switch 156 and a variable resistance 118. The means for securing the webs together comprise sheets of paper or other suitable material, which are folded, as shown in Fig. 14, the parts being held together by strips of adhesive 125 to form pockets 124 by which the sheets, which have their outer sides coated with adhesive, are mounted on flexible fingers 130, Fig. 8, carried by holders 131 loose upon a shaft 131<1> and having arms 133 connected to the armatures of solenoids 135. The shaft 131<1> and solenoids are carried by members 132 which may be raised and lowered by racks 137 operated by pinions 141 on shaft 142 having an arm 143 provided with an operating cord 144. Excitation of the solenoids turns the arms 130 to bring the adhesive sheets into contact with the roll B, whereby they are stripped from the fingers and carried round to adhere to the expiring web. The application of the sheets to the leading end E of the reserve web is ensured by a timing device consisting of a disc 150 of insulating material fixed to the chuck 4 and provided with a conducting inset 151. The disc 150 engages two pairs of brushes 152, 153, Fig. 10, mounted on the frame. The brushes 153 are connected to the mains in circuit with a resistance 157 and a solenoid 158 and through a press-button switch 161, and the solenoid 158 controls a switch 162 in the lead connecting one of the brushes 152 to one main. The other brush 152 is connected to the other main through the solenoids 135. When the join is to be made, the switch 156 is closed to operate the motor 107. When the roll is rotating at the correct speed, the switch 161 is closed. Upon the strip 151 bridging the brushes 153, the solenoid 158 is excited to close the switch 162 which is held closed by current passing through the resistance 157 so that upon bridging of the brushes 152 by the strip 152, the solenoids 135 are excited and the fingers 130 actuated. In a further modification, Fig. 17, the adhesive sheets are applied to the expiring web instead of to the reserve web, the apparatus being otherwise similar to that shown in Fig. 8. Mounted on brackets 185 on the stand 2 are rotatable shafts 187 provided with notches 188, Fig. 19, to receive the flattened ends 189 of a removable rod provided with fingers 1301 to receive the adhesive sheets. Arms 190 fixed to the shafts 187 are attached to the armatures of solenoids 135<1> which are connected and actuated in a similar manner to the solenoids 135 of Fig. 8. Specification 385,337 is referred to.

1,180,824. Cathode-ray tube circuits. XEROX CORP. 1 March, 1967 [7 March, 1966], No. 9803/67. Heading H4T. [Also in Division G2] In photographing a document 2 of which selected parts only are required for reproduction, the unwanted parts are blanked out by a flying spot cathode-ray tube scanner, so that the blanked out parts are over-exposed and do not reproduce on the final photograph. It is assumed, by way of example, that the document comprises a picture 12 and text 11, and that the picture is to be blanked out, leaving the text only to be reproduced. As shown, ramp waveforms 120 and 122 are similar in shape to the horizontal and vertical deflection waveforms respectively applied to the cathode-ray tube. Two points H1 and H2 represent two values of voltage amplitude on waveform 120, and V1 and V2 two similar values on waveform 122. These points can be set by potentiometer controls H1, H2 in the masking control circuit 30, Fig. 4, and points V1 and V2 similarly set. These adjustments cause the horizontal input diodes DH1 and DH2 in an AND gate 34 to be non-conductive during the period of deflection amplitude between points H1 and H2 on waveform 120, and similarly for diodes DV1, DV2. Thus an illumination pattern corresponding to the picture area 12 is superimposed on the document, blanking out that area and leaving only the remaining area 11 to be recorded.

1533099 Lithium tantalate single crystals TOKYO SHIBAURA ELECTRIC CO Ltd 9 March 1977 [17 March 1976] 9863/77 Heading B1S [Also in Division C1] A lithium tantalate single crystal is drawn from a melt of lithium tantalate contained in a crucible made of 80-60% Pt-20-40% Rh by crystal pulling. The crystal may be grown by a pulling up, pulling down or lateral pulling method, especially the Czochralski, Kyropoulos or edge defined film fed growth methods. The crystal formed contains 70-700 ppm of Rh and exhibits a dislocation density of less than 5 x 10<SP>2</SP> lines/cm<SP>2</SP>. The temperature coefficient of the crystal to the propagation velocity of a surface wave is reduced from about 22 ppm for a substrate at an angle of 90 to the X-axis to 18 ppm and thus finds use as a frequency filter for colour television receivers.

Brake system for articulated vehicles
|
en
|
The fifth wheel (3) of an articulated vehicle comprising the coupling between a semi-trailer (2) and a tractor (1) is provided with measuring apparatus for measuring forces imparted from the semi-trailer. The apparatus comprises a sensing device (5) for measuring horizontal loads (AD), and a sensing device (6) for measuring vertical loads (W). The signals from the sensing devices (5) and (6) are fed into an electronic controller (26), in turn to cause the brakes (27) on the trailer (2) to be applied to achieve balanced braking, anti-lock control, and traction control of the wheels. We can therefore use a tractor fitted with a braking system of the brake-by-wire type with a conventional semi-trailer, without modifications to semi-trailer or to the braking components of the semi-trailer.

A vacuum cleaner head, for attachment directly to a vacuum cleaner body having a central longitudinal axis, has exposed bristles with remote ends on a plane off-set by about 70 DEG to the central axis. The bristles 14 and IS extend along opposing sides of a lower surface of the head in strips at either side of a channel 18 through which dust and debris gathered up by the bristles passes into the vacuum body. The off-set plane means that when the body is held directly or by a handle, a natural comfortable sweeping action, with the handle axis at about 20 DEG to the vertical, keeps both strips of bristle in contact with the swept surface. <IMAGE>

PROBLEM TO BE SOLVED: To provide a structure of a fine semiconductor element for realizing a hyperfine wiring and a semiconductor element in nano-meter order. SOLUTION: A structure 6 of a fine semiconductor element includes a semiconductor substrate 1, a semiconductor projected part 4 formed continuously according to a desired pattern with an epitaxial relation with the semiconductor substrate 1, and a metallic layer 5 selectively mounted on the semiconductor projected part 4. As an example, a plurality of metallic super-minute particles 2 are arranged according to a desired pattern on the semiconductor substrate 1 and treated by heat in a vacuum atmosphere. After a constituent element of the semiconductor substrate 1 is put in a solid solution state (or further melted) into the metallic hyperfine particles 2, the semiconductor substrate 1 is put in a gradually cooling treatment so that the constitutent element of the semiconductor substrate 1 is separated by sedimentation from the solid solution phase (liquid phase) and grown during the sedimentation. In this way, the structure of a minute semiconductor element can be obtained.

PURPOSE:To provide a semiconductor device, which is provided with a MOSFET that has source/drain regions formed of a high concentration region and a low concentration regions and protects an internal circuit from a high voltage from the outside, and provide its manufacture. CONSTITUTION:A P-type impurity diffused layer 11 is formed on the external side of the source/drain regions 9 of an N-channel type MOSFET 10. The width of the side wall spacer on the gate electrode sidewall of a MOSFET is permitted to be narrower than the width of the sidewall spacer on the gate electrode sidewall of other MOSFETs. Therefore, the reverse direction breakdown strength of a junction diode formed between the source/drain regions 9 and a substrate is reduced to the insulation breakdown strength of the gate film or lower so as to prevent high potential on the gate film and an internal circuit is protected from a high voltage from the outside.

PURPOSE:To amplify a signal having normal amplitude smoothly, just after an interference signal such as click having a further larger amplitude than an excessive amplitude considered in sound signals is given. CONSTITUTION:When the interference signal such as click having an excessive amplitude is inputted fom an input terminal 1, just after the amplitude of the interference signal exceeds the range of discriminating level and is returned in the discriminating level range, a transistor (TR)54 is conductive momentarily. Then, the charge in a capacitor 22 is discharged and decreased in the range where TRs 27, 28 are inactive. Thus, just after the interference signal having the excessive amplitude is relinquished and the TR54 is conductive, the TRs 27, 28 are interrupted and the input signal from the input terminal 1 is given to an amplifier circuit 4 for amplification without being attenuated at an attenuation circuit 3.

Load raising-lowering device
|
en
|
PURPOSE:To prevent breakage caused by a drop of a raisinglowering mechanism by giving an alarm when looseness of a turing mechanism is detected beforehand, and arranging a drop preventive plate. CONSTITUTION:A raising-lowering mechanism 1 is suspended from the ceiling through a turning mechanism 2 and a fixed pole 3, and a fastening nut 27 is arranged in a lower part of a fixed side shaft 5 so that the turning mechanism 2 is not loosened, and a drop of the raising-lowering mechanism 1 is prevented. A drop preventive plate 28 is fixed the lower part of the fixed side shaft 25 by a bolt 29, and a looseness detecting switch 30 is installed, so that even if the fastening nut 27 to fasten the turning mechanism 2 is loosened, the looseness detecting switch 30 is operated in the first place and informs abnormality by outputting a detecting signal. When the looseness detecting switch 30 runs into trouble, or when the fastening nut 27 is loosened and disconnected completely until maintenance and inspection are carried out after the abnormality is alarmed, a bracket 26 is supported with the drop preventive plate 28, so that a drop of the raising-lowering mechanism 1 can be prevented. In this way, a safety measure of two stages is adopted.

Voltage controlled oscillator circuit
|
en
|
PURPOSE: To obtain the voltage controlled oscillator circuit operated at a low power supply voltage and at a high speed, with low power consumption and excellent duty ratio control performance. CONSTITUTION: First and second dynamic latch circuits 8, 9 generating an oscillation output are formed by connecting P-channel and N-channel MOS transistors(TRs) in series and providing an output terminal to the connecting point, invert the output depending on a gate voltage of each MOS TR and latch dynamically the output state. Since the inversion is conducted by activating the respective MOs TR with the charging voltage of 1st and 2nd capacitive elements 4, 6 charged/discharged by the output and 1st and 2nd comparator circuits 5, 7 receiving the charging voltage, the operating speed is higher than that of flip- flop circuits and a higher oscillating frequency is obtained. Furthermore, the MOS TRs are not simultaneously conductive and a through-current is suppressed. Since the inversion timing depends on the charging speed of the 1st and 2nd capacitive elements 4, 6, excellent duty ratio control performance is obtained.

Developer of resist
|
en
|
PURPOSE:To obtain the titled developer having the lowest swelling property during developing, and a good resolution property, without remaining a fine resist, by incorporating acetone or methyl ethyl ketone as a main component to the titled resist. CONSTITUTION:The titled developer is applied to a resist image forming method in which the resist material composed of a mixture of polymethoxystyrene and polystyrene having a chloromethyl group makes insoluble by irradiating an electron ray, an X ray, an infra UV ray or an ion beam, and by dissolving out an unirradiated part and removing said part to form a resist image, and consists of a solution comprising acetone or methyl ethyl ketone as a main component. Acetone or methyl ethyl ketone elutes the unirradiated part without remaining said part, and makes a less swelling during developing. Therefore, as the resist image is formed without remaining any resist residue of the unirradiated part, acetone or methyl ethyl ketone may be independently used. The swelling may be further depressed by mixing a solvent which is poor in the solubility, for example, isopropyl alcohol.

Quick response servo-balacing type speed voltage generating circuit
|
en
|
PURPOSE:To quickly respond with a high precision and a high stability by counting pulses outputted from a pulse encoder and a carry signal outputted from an integrating means and loading the operation result of an operating circuit at interval of a certain time. CONSTITUTION:A reversible counter 1 counts positive pulses +P or negative pulses -P outputted form a pulse encoder (PG) and pulses of the carry signal outputted from an ALU 7 and is cleared at every certain period T. A D flip-flop 2 latches the counted value each time to output it as a counted value N1. That is, the counted value N1 is zero when the PG is rotated at a certain speed, and it is outputted as the error to be corrected corresponding to the acceleration when the rotation number of the PG is changed. The counted value N1 is added to a counted value N, which indicates the pulse rate of the PG, outputted from a reversible counter 6 by an ALU 3, and the result is loaded as a counted value N2 to the reversible counter 6 at intervals of the unit time T. Thus, the counted value N outputted from the reversible counter 6 is substituted with the counted value N2 at intervals of the unit time T to resolve the error.
