Title: Improvements in or relating to perforated card controlled machines particularly tabulating machines
Filed: 1946-06-06
Abstract: 620,155. Statistical apparatus. COMPAGNIE INDUSTRIELLE DE MACHINES AUTOMATIQUES DE COMPTABILITE. June 6, 1946, No. 17194. Convention date, July 24, 1943. [Class 106 (i)] [Also in Group XXXVII] A record card controlled machine having pintype sensing devices and a connection box comprising contacts (8, Fig. 1) which are closed when a sensing pin (9) passes through a card hole whereby electric current actuates means (1) controlling appropriate recording means (3), is characterised in that provision is made for quickly changing the electrical connections (4, 11) to permit control of any selected recording means by any sensing device. A -sensing pin 9, Fig. 6, passing through a card hole thrusts a corresponding pin 14 and through a Bowden wire 12 and spring 17 a member 8 bridges contacts 7, 7a to energize a corresponding electromagnet 1, Fig. 2a, the armature 1a of which is connected to a small bell-crank 74a which, in turn, is connected by a piano wire 75 to one of a set of members 2, Fig. 2b, controlling recording means. Each of the members 2 has a pin 39, Fig. 7, passing through its upper end and resting on a support 38, thus providing for movement of each member 2 about its supporting pin. The lower end of each member 2 comprises a further pin 40 movable in a cam slot 41 of a bar 13 which is adapted to be given an upward movement at an appropriate time in the machine cycle. The cam slot is so shaped that when the pin 40 is pulled over to the left by an electromagnet 1, bell-crank 74a and piano wire 75 as described, the member 2 concerned is carried upwards with the bar 13 and operates the recording means. When the pin 40 is at the right of the slot 41 the member 2 is unaffected by upward movement of the bar 13. Instead of the cam slot 41, the lower end of each member 2 can be shaped to co-operate with lug 60 on the bar 13 as shown in Fig. 8. After operation, the members 2 are positively restored to their inoperative positions by pins 44a on a bar 44 operated through a rockable member 56, a pivoted sector 51 and a roller 52 moving with the frame 32. For quickly changing the connections between the contacts 8a and the electromagnets 1, a plug-board 4 is provided, accessible through a door 91 released by a hand wheel 98 and hinged about trunnions 85 at its upper edge. The plugs 121, Fig: 1, are connected by flexible cables 11 to connecting devices 11a connected to the sensing pin actuated contacts. A mercury master switch 6 (see Group XXXVII) is introduced into the supply line to the magnets 1 and is normally spring-urged to the " off " position, being rendered operative for a limited period only in each machine cycle.

Abstract: 1,247,227. Ratchet clutches. H. M. HOBSON Ltd. 1 July, 1970 [2 April, 1969], No. 17341/69. Heading F2C. In a ratchet clutch for transmitting drive in both directions and overrunning in both directions wherein rollers 1 carried by an intermediate member 4 wedge between cam recesses (19) in a driving race 5 and a cylindrical outer driven race 10, the intermediate member 4 carries friction plungers 7, 8 urged radially outward by springs 17, 18 into engagement with a fixed ring 9 and the driven race 10. The intermediate member 4 is connected by spring pins 3 to the driving race 5. During initial rotation of the driving race 5 the friction plungers 7, 8 hold the intermediate member 4 and rollers 1 against rotation whereupon the rollers 1 ride up the cam surfaces of the recesses (19) into wedging engagement with the driven race 10. The springs 3 being weaker than the frictional force to permit this action. On overrun the friction plunger 8 tends to rotate the intermediate member 4 whilst the plunger 7 tends to hold the intermediate member and these opposite forces tend to cancel and permit the springs 3 to centre the intermediate member relative to the inner race 5 for clutch disengagement.

Title: Improvements in and relating to metal detectors
IPC: G01V3/10
Filed: 1948-06-29
Abstract: 677,773. Locating conductors. KERR, B. G., and HISCOCK, D. July 29, 1949 [June 29, 1948], No. 17443/48. Class 37. In a metal detector, the responsive device is affected only by changes in the state of balance of a bridge when a metal object passes the detector coils and not in accordance with the permanent state of balance, and so is unaffected by slow changes due to ageing &c. of the circuit components. As shown, the bridge comprises four coils L1-L4, of which L3, L4 are the search coils. The unbalance A.C. voltage after amplification is rectified by a diode V3 followed by a filter R5, C2, which suppresses residual A.C., and is fed to the following stage by R.C. coupling R6, C3, so that there is no input to the next stage except when the bridge output is varying and no effect is produced by slow changes such as caused by drift. To ensure equal response to unbalance voltages of any phase, caused by ferrous or non-ferrous material, an initial unbalance is introduced by a resistance R3 in parallel with coil L3. The change in unbalance voltage may thus be positive or negative, and is fed to an indicator stage comprising two R.C.-coupled valves V4, V5, the latter including a relay winding A/2 in its anode circuit, which releases on receipt by V4 of a positive signal, or on the termination of a negative one, from diode V3, and closes contacts A1, A2 to lengthen the period during which the signal is effective.

Title: Anti-aircraft weapon carriage
IPC: F41G5/08
Filed: 1965-04-27
Abstract: 1,108,072. Fire control apparatus. BOFORS A.B. 27 April, 1965 [5 May, 1964], No.17743/65. Heading G4G. [Also in Divisions F3 and H4] Relates to the control of an anti-aircraft gun V; Fig. 1, elevatable in a turret by a servomotor MV, the turret being rotatable about a vertical axis by a servomotor MT and carrying a radar aerial positioned in traverse relative to the turret by a servomotor MS about an axis parallel to turret rotation and in elevation by a servomotor MH. Radar apparatus on the turret produces an error signal e s  representing the traverse angle between true target direction and aerial direction, an error signal e h  similarly in respect of elevation, and signals Al 1 , Al 1  representing target slant range and its rate of change. The analogue computer, Fig. 2, in which D's represent demodulators, G's represent gyros, T's represent tachometer generators, R's represent resolvers and P's represent potentiometers, calculates a quantity sv 12  representing the traverse angle between the direction to a computed point of aim of the gun and the direction to the target and a signal e sv , representing the difference between quantity sv 12  and a quantity representing the traverse angle between the aerial direction and that of the gun, controls servomotor MT. Quantities (i) hv 2 representing the elevation angle to the point of aim for controlling servomotor MV, (ii) hv 1  representing elevation angular acceleration of the target, and (iii) sv 1  representing traverse angular acceleration of the target are computed. The radar sight cannot accurately determine the target azimuthal and elevational angular velocities of the target with respect to the ground because of the rotation of the turret, the elevation of the gun and its firing; therefore the control signal for servomotor MS includes a signal proportional to the traverse angular velocity of the aerial relative to the ground by means of tachometer generators T1, T2 and a gyro G1 mounted in the vehicle's chassis. It is assumed that the target is moving on a straight course with constant speed, and projectile time-of-flight t is taken into account. The Specification develops the necessary equations including trigonometric functions inserted in the computer by resolvers R. In Fig. 3 point O represents the gun carriage, point P 1  the target and point P2 the point of gun aim. Time of projectile flight t is given by the output shaft of a servomotor MTS, the equation being utilized, where Al 2  is slant range 0P 2 , V o  is the known initial projectile velocity, c is a constant dependent on the air density, k 2  is a constant and Av 2  is vertical height to point P 2 .

Abstract: 759,909. Feeding sheets. FRENCHAY PRODUCTS, Ltd., and MILLEDGE, S. Z. Sept. 27, 1954 [June 29, 1953], No. 17986/53. Class 100 (1). Apparatus for removing sheets in succession from a pack comprises a rotor which carries a suction nozzle and is mounted rotatably on a carrier, means for rotating the rotor to move the nozzle around an orbit, and means for moving the carrier bodily whereby the nozzle is given a reversed movement relative to the pack while it is disposed in a position where it receives a sheet from the pack. Pile supports.-A pack of labels or sheets 21 is contained in a magazine 19, Fig. 2, of oval cross-section, and is pressed to the left by a weight mounted on wheels, so that the front sheet is held against abutments comprising a roller 24 and flanges 25, 72. Sheet separators and forwarders.-The sheets are withdrawn in turn by three suction nozzles 56, Fig. 2, rotating in an orbit such that a point 68 on one of them follows counter-clockwise the path shown in dot-and-dash line. At the point 69 the upper part of the front sheet is held by a nozzle, moved downwardly to clear the flange 25, and then upwardly to clear the roller 24. The sheet is then carried round until at the lowest part of the orbit the suction is released or compressed air is applied and the sheet is dropped into one of a series of jars being fed on a conveyer. The nozzles 56 are surrounded by sleeves 58, Figs. 3 and 4, of rubber or like material having poor electrostatic properties, and have nozzle orifices 57. The nozzles are carried on a rotor member 54 mounted on a spindle 51 carrying a gear 49, and the spindle is supported within a cylindrical valve block 38 carried on the lower end of an arm 16 supported by a head 33 on a fulcrum 17. The spindle 51 also supports an arm 40 having a crank pin 41. The pin 41 is secured to a disc 42 rotated by a source of power through a shaft 26, sprocket 27, chain 28 and sprocket 29 so as to oscillate the arm 16. The pin 41 carries a pinion 48 meshing with the gear 49 so as to rotate the nozzles. These two motions produce the cusped path shown. A source of vacuum is connected at 36 to the bore 34 of the fulcrum 17, and thence by the interior of the arm 16 to the valve block 38. Ports 60, 61 are arranged to maintain each nozzle connected to the vacuum during most of its revolution and connected to atmosphere during a small period beginning at the bottom of the orbit. In another form, Fig. 8, the arm 16 is replaced by a member comprising two tubes 78, 79 connected respectively to passages 80, 85 and sources of vacuum and compressed air, and to the vacuum port 60 and a port 92. The tubes 78, 79 are held together by a spring 95 and flexible straps 96, 97, so as to keep nipples 82, 83, 88, 89 pressed into their sockets, and a plate 99 bifurcated at each end and carried by a rod 98 secured to the head 33 keeps the tubes in their correct relationship to the head.

Title: An improved process for reclaiming paper
IPC: D21B1/32
Filed: 1943-11-03
Abstract: Waste paper products impregnated or coated with oils, waxes, resins, bitumen, or like water-or grease-proofing substances are utilized for the production of fresh paper products by subjecting them to treatment with the vapour of a solvent or solvents of the particular proofing substances in the products under treatment, and the vapour is allowed to condense upon the paper materials so as to dissolve and remove the proofing substances.  The treated paper material is then re-pulped.  Preferably, a solvent having a boiling point in the region of 100 DEG  C., e.g. a petroleum spirit or a mixture of benzene and toluene, is used.  The solvent vapours which may be produced inside or outside the extraction vessel condense on the large cooling surface of the paper, thereby melting and dissolving the coating or impregnating material and forming highly-concentrated solutions, and at the same time heating the paper up to the boiling point of the solvent.  The solution formed is removed into a still and the solvent is recovered by distillation and condensation, leaving the solute in the still.  The hot paper is treated with live steam to remove the adhering solvent, and it emerges from this treatment in a dry state since there is practically no condensation of steam upon it.
