(Eastman Pacific Co.). Jan. 13, 1955, No. 1041/55. Class 102(1) [Also in Group XXIX] A rotary hydraulic pump or motor comprises a fixed body 10 having an internal cavity 14 closed at each end by end plates 11, 12 the cavity having two angularly disposed adjoining cylindrical sections with their axes intersecting, a cylinder block 15 rotatably mounted in each cylindrical section and providing between them a central space in the cavity 14, each block having a plurality of cylinder bores 18 parallel to its axis and a plurality of angular piston members 20 slidably mounted in corresponding bores 18 of the two cylinder blocks 15 and drivingly interconnecting the blocks. The cylinder blocks 15 are free to move a small amount axially to provide space for a fluid film between each cylinder block and the adjoining end plates and to allow the cylinder blocks to be seated against the fluid films by intermediate pressure which builds up in the central space, the effective area on the outer end of one cylinder block 15 bearing against said fluid film being equal to the similar area on the other block. The end plate 11 is provided with an inlet connection 25 and an outlet connection 27 which communicate respectively with arcuate ports 28, 29 with which the cylinder bores communicate as the block rotates. The port 28 is connected by a passage 33 to a similar port 31 in the end plates 12. A recess 32 corresponding to the port 29 is provided in the end plate 12. One block 15 is provided with a central recess 44 which is connected by a passage 43 to the inlet port 28. The other block 15 is driven by a shaft 37 and is provided around the shaft with a recess 38a which is connected through the bearing 40 for the shaft 37 to the inlet port 31. A passage 46 is provided in the housing 10 and extends between the end plates 11, 12 and communicates with the central space. The housing 10 is provided with a further passage 35 corresponding to the passage 33 so that the delivery of the pump may be reversed by turning the end plates 11, 12 through 180 degrees. In a modification, Fig. 13 (not shown), the port 29 is duplicated in the end plate 12 and the passage 35 connects the two ports, and the recesses 44, 38a are connected to the inlet and outlet ports by passages which are controlled by four valves. In this embodiment reversal of delivery is obtained by reversing the direction of rotation. In a further embodiment the inlet and outlet connections are provided in the body 10; each end plate has inlet and outlet ports which are connected by passages in the body and the pistons 20 are solid. The Specification gives formulµ for calculating the diameters of the recess in the end face of the block, for the outside diameter of the cylinder blocks and for the area of the annulus defining the ends of the cylinder bores 18, in relation to the crosssectional area of the bores in the cylinder block. In order to maintain the end face of the block and end plate parallel the end plate may. be tilted by an amount corresponding to the tilt of the block. | en |

Ionospheric radio sounding. E.M.I.-COSSOR ELECTRONICS Ltd. Jan. 10, 1964 [Oct. 29, 1963], No. 1287/64. Heading H4D. The invention relates to apparatus for displaying on a C.R.T. responses in a constant direction to successive pulses of ascending frequency, wherein as well as the responses to each pulse being displayed on a horizontal intensity modulated scan, the scan being positioned vertically according to the pulse frequency (i.e. frequency range modified type B display), the amplitudes of the responses at any desired frequency may be superimposed on the display as a type A display. In particular the invention may be applied to an ionospheric sounding system wherein soundings are taken on an oblique path and produce the shown display, each pulse producing responses displayed on a horizontal scan such that range (time) indication is horizontal and each scan being displaced upwards from the last, in accordance with the increasing frequency. Ionospheric layers are indicated as at 22, their heights being indicated by the horizontal positions of their traces and the ranges of frequencies they reflect being indicated by the vertical extents of their traces. The frequency sweep waveform which controls the pulse frequency also controls the vertical deflector plates of the C.R.T. and is fed to a Schmitt trigger circuit having its trigger level determined by a potentiometer. The potentiometer is set such that when the sweep waveform has climbed to a level indicating that the desired pulse frequency has been reached, the trigger circuit triggers, and via a differentiating circuit and a mono-stable multivibrator operates a switch for one scan period, such that the responses are removed from the control grid of the C.R.T. and are applied to the vertical deflection plates thereof. The type A display is thus produced. | en |

A typical undulation is shown in Fig. 3, in which a relatively narrow valley 5 is formed between relatively extensive crests 4. Mathematical formulae are given in the Specification whereby suitable dimensions for the valleys and the crests can be computed in any particular case, the dimensions depending on, inter alia, the latent heat of condensation of the vapour and the density, viscosity and surface tension of the condensate. Fig. 4 shows the application of the invention to a compression apparatus suitable for the distillation of sea-water. The sea-water is supplied by pipe 12 to a distributer 13 which spreads it as a film over the inner surface 2 of a cylinder 1, the distribution being assisted by wipers 17 mounted on an axial shaft 14 rotated by a motor 15. The distillation residue is discharged through pipe 29, and the vapour rising from the surface 2 passes through passages 20 in the distributer 13 to a compressor 10, which delivers it to the space between the cylinder 1 and an outer cylinder 27. The outer surface of the cylinder 1 is fluted as described above, and condensate flows down the grooves to a discharge pipe 28. | en |

In the case of a three band filter the central zone is the largest and is red. Impermeable strips may be placed between the bands, or the areas of the bands delineated by a diaphragm either of rectangular form or as shown in the Figure. To determine the average length of a zone bounded by curved edges, the zone is divided into a number of elementary strips, the total length of which divided by the number of strips is taken as the average length. | en |

Screw - and - nut actuators. ENGLISH ELECTRIC CO., Ltd. Jan. 19, 1948, No. 1633. [Class 78 (iii)] [Also in Groups XXIV, XXXIII and XXXVII] A screw jack actuator is driven alternatively by a main and an auxiliary electric motor which operate respectively on two of the three main components-sun-wheel, planet-wheel carrier and annulus-of an epicyclic gear, the third component being geared to the mechanical part of the actuator. The main motor drives the sun-wheel 7 through a friction clutch and a speed-limiting device and since the annulus 19 cannot revolve, it being restrained by the braked auxiliary motor 22 and the gear train 15-19, the planet-wheel 6 rotates causing the carrier 5 to drive, through the gear train 4-3-2, a screw jack spindle 1 of the actuator. In an emergency the auxiliary motor 22 is energized together with its electromagnetic brake 21 and the electromagnetic brake of the main motor, normally free, is braked whilst the auxiliary motor, normally braked, rotates and drives, through a speed-limiting device 20 and the gear train 19-18-17, a pinion 16 meshing with internal teeth 15 on the annulus 9 causing the annulus to rotate in the needle bearings 10. As the sun-wheel 7 is held stationary by the main brake motor the planet-wheel 6 will rotate and be displaced taking the carrier 5 with it and applying to the spindle 1 substantially the same torque as normally applied by the main motor. In another embodiment, Fig. 2, Provisional Specification (not shown), the auxiliary motor drives the planet-wheel carrier and the annulus drives the screw jack spindle. A circuit diagram (see Group XXXVIT), is given in Fig. 3 (not shown) for a reversible motor and a unidirectional auxiliary motor having separate supplies. | en |

Class 106 (1) A combined cheque-sorting and accounting machine, of the type comprising sorting compartments for the individual cheques of a group and an amount entering keyboard under control of which successive entries are effected in a group totalizer, is. provided with storage means under control of the keyboard to store up a total entered directly at the conclusion of the successive entries, and comparing means for effecting a comparison of the stored total with that on the gtoup totalizer to determine whether or riot there is agreement. The machine described is similar to those described in Specifications 435,139 and 498,429, and comprises a compartmented rotatable drum into which a group of cheques accompanying a deposit slip are sorted (according to banks upon which they are drawn), separate totalizers for the individual cheque compartments, a group totalizer cleared after each group of cheques has been entered and totalized, and a grand totalizer. The invention provides means for proving the entries by comparing the total on the group totalizer with that written on the deposit slip and entered by the operator during a concluding group balancing operation. If there is disagreement, a warning light appears; the operator investigates and corrects the error and then presses a release key which enables him to proceed with the next group of cheques. The drum has 24 cheque-receiving compartments se'ected by press-button switches which mark contacts of a rotary hunting switch fast with the drum and controlling forward and reverse clutches in the drum drive; so that the drum rotates in the shorter direction to position the :compartment at the receiving aperture. Means are provided for accurately positioning the drum and for damping oscillation as it comes to rest. Amount differential.-The amounts on the cheques are entered By means of the ten-key pin carriage mechanism described in Specification 694,698. Set pins 210 (Fig. 10) of the carriage 212 differentially arrest in succession slides 238 on the carriage, the set slides successively coming below control s'ides 272 as the carriage advances step-wise. During cyc ic operation of the machine the s'ides 272 are first lowered in a pivoted supporting frame to bring hooked forward ends 271 into the plane of studs 270 at the extremities of the slides 238, and are then released to springs to take up the differential setting of the slides, a bail 332 (Fig. 18a), restoring them during the second half cycle. The slides 272 are linked by bell-cranks 330 with vertical bars 376 (Figs. 18a, 18b) carrying type e'ements 382 and tota izer actuating racks 383-4-5. An aligner 435 (Fig. 18b) holds the bars 376 in their upper differentially set positions during printing, check pawls 490 then becoming effective to hold them pending return by the bail 332, the slides 272 then having been raised clear and released from the studs 270. Subtraction:-The slides 272 of unset orders are adapted to be held in a sub-zero position by a bar 325 (Fig. 10) projecting laterally from the pin carriage. Operation of a subtract key 177 lowers this bar so that nines are entered in the unset orders, the operator entering complements in the others. Interlock contacts associated with the pin carriage and subtract key prevent energization of the machine drive clutch magnet when no amount has been entered. Totalizer selection and engagement in odd timing.-The individual totalizers 390 (Fig. 18b) for the cheque compartments are carried between spaced discs 393 (Fig. 18b), 394 (Fig. 21b) rotatable with the drum on a shaft 11. Springs 396 hold the totalizers normally retracted and engaged by locking bars, but the spindle 391 of that corresponding to the selected compartment enters between guides 399 at the extremities of pivoted arms 400 rockable by cam-slotted arms 404. An add engaging slide 410 lifts the arms 404 at the beginning of the second half cycle, thus engaging the selected totalizer with the racks 385 on the bars 376, so that the setting of the bars is added to the se'ected totalizer as these bars restore downwardly. Similar mechanism, operable by the s'ide 410, is adapted simultaneously to engage the grand totalizer 450 (Fig. 18a) and group totalizer 451 with their respective racks 383 and 384. A plug circuit may be established by the operator to disengage the group totalizer when certain cheque compartments are selected. A solenoid 1408 (Fig. 21 b) is energized which disengages the arms 404 from the add engaging slide 410. A similar arrangement is provided retaining the grand totalizer disengaged. Transfer mechanism.-The racks 383-4-5 have an additional step of downward movement when transfer from a lower totalizer wheel occurs. The racks are pin-and-slot connected to the bars 376 and have identical means for effecting the addi- - tional movement. As regards the racks 385, pawls 461 normally lock the racks to their bars, the lower wheel transfer tooth tripping the pawl so that the rack moves downwardly under spring action. Latches 465 (Fig. 28b) hold tripped pawls clear until the commencement of the next adding cycle, when bai's 470 trip the latches, and crossbars 482-3-4 of a frame 480 reset the racks in engagement with their pawls. The frame 480 and bails 470 are both actuated by a common rock-sha't 475, the frame through a pin-and-slot connected arm 485 and the bails through an arm 474 and depending rod 472. Main control tape printer.-Spring-actuated hammers 504 impress the types 382 on a main control tape 507 (Fig. 18a) after release by bail 508. Detents 521 hold the hammers a'ter their release by the bail until an extension 530 of the bail trips the detents by engagement with a step 527 in a bar 524 connected with each detent. Cheque compartment printers.-The separate printing mechanisms for the 24 cheque compartments are arranged in 3 vertical groups of 8 mounted in removabe sub frames at the back of the machine (Figs. 18a, 18b and 21b). Associated with each is a differentially settable type sector 550, pivoted on a shaft 551, from which impressions are made on a record strip 591 by means of a spring-actuated hammer 567. The sectors 550 of one of the printers have toothed segments 555 by which they are adjusted from the bars 376 through a lever 557 formed with co-operating gear teeth 556. The sectors of the remaining printers are adjusted simu'taneously, vertical bars 554 effecting interconnection between sectors in the ordinal co'umns, whilst interconnection between corresponding orders of the 3 groups is made through the shafts 551 and two further shafts 561, 562. The hammers 567 are operated individually, each by clockwise movement of a respective lever 580 (Fig. 22). A pawl 587 on this lever carries forward an arm 579 secured to a shaft 570 until tripped by a stop 588, whereupon the shaft 570 returns sharply under spring tension to operate the hammer. Selection of the hammer to be operated is by a heart-shaper cam 640 (Figs. 18b, 27) turning with the cheque drum and totalizers. A fo'lower 642 differentially positions a bail 649 straddled by depending arms 654, 660 (see also Fig. 18a) and 666 of bell-cranks 651, 656, and 663, connected to three vertical slides 625, 626 and 627 each bearing eight lugs 637. By this means, the slides are selectively and differentially positioned so that a lug 637 on one registers with a stud 638 (Fig. 22) on the hammer operating lever 580 of the printer appropriate to the drum compartment selected. During the ensuing machine cycle, a cam-slotted lever 636 (Fig. 21b) swings a support lever 633 for the 3 slides À and moves the slides rearwardly so that the selected lug 637 drives its hammer operating lever 580 to print the set amount. Zero elimination.-Zeros in unset orders are not printed owing to the slides 272 and bars 376 being he'd in a sub-zero position by the bar 325 of the pin-carriage. In total-taking, however; the slides 272 are raised clear of the pin-carriage and other mechanism then becomes effective. As regards the control tape printer, if a bar 376 is not raised above zero, a pin 526 thereon retains the bar 524 depressed and clear of the bail extension 530 so that the printing hammer 504 is not. re'eased. Offsets 532 on the hammer detents 521 ensure tripping of all hammer detents below the highest significant digit. As regards the cheque compartment printers, zero eimination pawls 779 (Fig. 29) are adapted to return slides 272 at zero into the sub-zero position. Upon operation of the total key, a rod 782 lowers these pawls towards the slides and, after the slides have been set by the totalizer, the pawls are drawn forwardly and downwardly over a stationary rod 800 by forward movement of their support rod 778. Shoulders 777 of the slides 272 in the zero position are caught by the pawls and carried back to the sub-zero position removing the type sectors from the printing line. The pawls interengage by means of pins 798 underlying lugs 799 of the next lower orders, so that the pawls in all orders below that of the highest significant digit are held, raised and zeros in such orders are printed. Total-taking.-Normally the se'ected compartment totalizer, the group totalizer and the grand totalizer, are all engaged with their racks in add timing, pins 412C, 412GP and 41'2GD on links 424 (Figs. 21b and 41) operating the engaging cams, being located in slots in the add engaging slide 410. Adiacent s'ide 410 is a slide 865 reciprocated in total-taking timing by means of a bell-crank 876 (Fig. 43) and a link connection 877 with a follower 879 engaging a main cam. This s'ide 865 also has three slots opposite those of slide 410 for engaging the pins 412, and between the pairs of slots are slotted lugs of a stationary bar 868 overlying the s'ide 410. Each pin 414 is adapted to be selectively | en |

Producing non-woven web structures. MONSANTO CO. 22 Jan., 1968 [27 Jan., 1967], No. 3265/68. Heading B5B. [Also in Division D1] A multifilament strand is deposited on a travelling collection surface in a randomly dispersed manner to produce a non-woven filamentary web structure having uniform thickness by extruding a fibre-forming material through a multiplicity of orifices to form a multifilament strand, advancing the strand through a combined aspirator and traversing means and on to the collecting surface with a high velocity jet or stream of fluid and alternately diverting the direction of travel of the strand toward one side of the web on the collecting surface and then to the other with a jet or stream of fluid at a velocity which is less than the velocity of the fluid advancing the strand. As shown in Figs. 2, 3 and 4, the combined aspirating and traversing mechanism comprises a housing body 10 containing an annular chamber 12 and a diverging cavity 13 interconnected by a passageway 14. The chamber 12 has a closure 15 provided with a hollow stem 16 extending to within close proximity of the entrance to the passageway 14. An element 17 concentrically disposed about the stem 16 has a plurality of passageways 25. The bottom portion of chamber 12 is flared to provide chamber 18 between element 17 and passageway 14. The closure cap 15 is provided with a passageway 22 which is in alignment with passageway 14 for receiving a multifilament strand 24. The aspirating medium, which may be a pressurized gas or liquid, is introduced into chamber 12 by means of pipe 26 and hole 27 and flows through the passageways 25 of element 17 into the chamber 18. In this chamber the high velocity fluid engages strand 24 with sufficient energy to draw the strand and forward it through the passageway 14 into the traversing zone of the apparatus which is the diverging cavity 13. Traversing of the strand 24 is accomplished by supplying a low-pressure fluid medium to the cavity 13 alternately through pipe 30 and port 28 and pipe 31 and port 29. The alternation of the supply of the medium may be effected by means of a programmed rotating valve of known type. As shown in Fig. 1, the combined aspirator and traverse assembly 40 is located in a fixed position above the foraminous endless travelling belt 32 mounted on rolls 33 to 35. A suction box 36 is provided immediately below belt 32 and the line of traverse to insure that the randomly dispersed filaments retain their respective positions after deposition. | en |

As applied to an apparatus for applying adhesive to the interior of bottle caps, the guard member consists of a ring 10 having a central aperture forming a seating for a small poppet valve 12, the lower surface of the ring being recessed to form a chamber 13. The ring 10 is screwed into a tube 18 which has a part 21 of larger diameter which is threaded and screwed on to the lower end of a tubular pot 22 containing adhesive. A spider 24 in the lower end of the pot carries a bearing 25 for a plunger 26, the upper end of which passes loosely through a hole in a rod 28, attached to vertically reciprocable portion 29 of a machine, and carries a nut 30 above, and a nut 31 and spring 32 below the rod. The lower end of the plunger is adapted to pass, with a sliding fit, through an aperture in a plate 35. The pot 22 is loosely surrounded by a projection 47 carried by the reciprocable member 29, an abutment 49 being fixed to the pot 22 above the projection 47 and a spring 48 being interposed between the latter and the part 21.

The pressure pump B is normally connected with. the pipe lines 12, 13 of a double acting slave unit A of which the pipe line 12 also passes on to a single acting slave unit G which acts to withdraw a latching pin when the slave unit A forms part of the retractible gear of an aeroplane undercarriage. In this main system a two-way control valve D is disposed for operating the slave unit in the required direction. If the pressure pump B is replaced by a hand pump E the valve F is set to connect the pump E with the main system. Non-return valves 23, 24 prevent one pump from feeding to the other. When it is desired to use the auxiliary system H with the hand pump E the valve F is set to connect up the pipe H and disconnect the pipe 22. The slave unit A and unit G have automatic valves 25, 26 each being in a casing having leads to the pipes 12 and H from unions 12a, 42, respectively. The union 12a communicates through a series of apertures 31 with an axial passage 32 of the annular valve seating 33. The valve 37 is provided with a rubber facing 41 and is under control of the spring 35. In normal working the pressure in the pipe line 12 holds the valve over to the left as in Fig. 2. If the main system fails and the auxiliary system is operated, pressure behind the valve forces it to the right shutting off the line 12 from the chamber 28 leading to the slave unit and opening up the line H thereto. The two-way valve F has a conical body 45 held on its seat by a spring 46 and provided with cut-out parts to form passages for connecting or closing the pipe lines. The body provided with a hole 55 whereby the rubber packing 50 is subjected to the liquid pressure. When two slave units A in parallel for simultaneous operation of an aircraft undercarriage are employed, with the hand pump E and mechanically driven pump B for alternative actuation as described in Specification 448,478, an automatic valve 25 is incorporated and a valve F is fitted on the system normally operating other slave units J from a hand pump K whereby on failure of the system E, 12, 13 the operation of the units A may be effected from the pump K. | en |

Printing-machines; feeding and delivering sheets. DAVIDSON, W. W. March 14, 1941, No. 3544. Convention date, March 18, 1940. [Classes 100 (i) and 100 (ii)] A rotary printing-machine is constructed with a cylinder 13, Fig. 1, which acts either as an impression or offset cylinder in coaction with a cylinder 12 of twice the diameter which can be fitted with a lithographic plate 20 co-operating with damping rollers 22 and inking rollers 23, and with an impression plate 21, or the cylinder 12 can be fitted with a typographic printing-surface co-operating with an impression blanket on the cylinder 13. The machine thus prints the upper side of a fed sheet with a typographic impression, or the lower side with an offset lithographic impression and the printed sheet in either case is delivered printed side up either into a box 67 or to an automatically lowered table. The sheets are fed by a conveyor 16 and side guide 91, to front stops 92 associated with dropping rollers 93, 94 of which the lower roller is driven by a camactuated gear 95 and advances the sheets so that at the time they reach grippers 36, Fig. 5, which are carried by sprocket chains 31 the sheets are travelling slightly faster than the grippers. The links of the chains have a seating engagement with the sprockets 32, 35. The grippers are fitted with curved registering stops 39, and owing to the faster rate of the sheets they buckle slightly when the stop is engaged. The gripper members 36 are carried by collars 49 adjustably secured to a rod 46 which is oscillated to open the grippers for receiving sheets by a lever arm 58 engaging a cam 62, and for delivery the grippers are opened by a cam 63 for delivering a sheet printed by the offset method. A stripping device 73 co-operates with the cam 63 to strip the sheet and cause it to be reversed so as to be delivered printed side up. The grippers 36 are freely'mounted and are pressed against the sheet by the action of springs 54 when the rod 46 is moved counterclockwise sufficiently far to move the surface 53 of a notch away from the face of the normally contacting gripper. The sheets are thus pressed with a pressure independent of the rotation of the rod 46. Some of the grippers are fitted with extra springs to ensure a good grip of the sheet so as to strip the sheet readily from the offset blanket. The chains 31 are driven by the sprocket 32, mounted on the shaft of the roller 13, and the sprocket 35 arranged below the sprocket 32 and at such distance therefrom that the grippers travel a distance equal to twice the diameter of the roller 13. The grippers are arranged so as not to contact with the roller 12. When typographic printing occurs the grippers are opened by a removable cam arranged below rollers 69, Fig. 1, which engage the margins of the sheets in conjunction with lower rollers of the sprocket shaft 71. This cam and the rollers 69 are put out of action when offset printing takes place. A chain guide plate 83 prevents flexing of the chain during action of the cam 63.

Figs. 1-3 (not shown) illustrate an arrangement in which a geiger counter for sensing radio-activity from a chromatogram is manually adjustable in position across the transverse dimension of the table, but is motor-driven in the longitudinal direction. In a more sophisticated arrangement, Figs. 4, 5 and Fig. 6 (not shown), at the end of a longitudinal scan of the assembly 14 carrying the detector 29, microswitches 118 (electronic, hydraulic or pneumatic) are actuated, causing motor/gear unit 112 to be operated and drive carriage 23 through an incremental distance, before a return longitudinal scan is carried out. In this way the whole surface of the layer medium 27 can be scanned. The unit 14, comprising carriage 23 and guide bars 20a, 20b &c. can be tilted away about pivot 15 to allow introduction of the layer medium, which is laid on the table top 1 and are held by two thin steel strips 28, which are attracted strongly by the magnetic table top, and thus prevent waviness and rucking of the layer 27. In an alternative form, the holding arrangement is a thin plate with a window. The material of the table top 1 is suitably of an aluminium alloy which has a uniform distribution of cylindrical seals in which are held ferrite pellets 11 to provide the magnetic field. The arrangement of Figs. 4, 5 includes a manually operable device, including handle 103 which frees the unit 14 from the motor drive and allows rapid positioning of the unit in the longitudinal direction. Alternatively, an automatic form may be provided which disconnects the drive from the normal scanning drive motor to ahigh-speed drive. Scales 114, 115 are provided for transverse and longitudinal position indication. Two measuring devices may be carried by the carriage 23, one above and one below the table. Each detector is adjustable in position vertically with respect to the table. The counter outputs may be integrated and printed out. The carriage may carry a marker device recording on a fixed sheet the detector output as the longitudinal scan progresses. The speed of traversing the surface may be adjustable or variable. Applications. - Besides chromatography, transmitting of the thin layer medium may be measured, a source on one side of the medium and a detector in the other, being carried by the carriage 23. Transparent zones in the table top are provided. Alternatively, by having source and detector on the same side of the material, reflection measurements are possible. Typical measurements are of colour densities, gloss, fluorescence, transparency, particle size. Radiation in the form of visible input and invisible near light wavelengths, alpha, beta and gamma are suggested. Ultrasonic energy, e.g. using echo techniques to determine surface condition, may be used. | en |
