Title: Improvements in and relating to toothed gearing
IPC: F16H1/22
Filed: 1919-11-24
Abstract: 159,028. British Thomson-Houston Co., Ltd., (General Electric Co.). Nov. 24, 1919. Driving-arrangements for screw propellers. - Toothed gearing suitable for gearing-down turbines in marine propulsion comprises double helical or other trains connected through torsional couplings, one of which has a greater resistance than the others so as to steady the high-speed driving-pinion in its bearing. Such pinion 6, Fig. 1, is mounted on a quill shaft connected through an axially-adjustable coupling 8<a> to an engine shaft 8. Two or more countershafts carry wheels 10 meshing with the pinion 6, and pinions 19 meshing with a driven wheel 16, which may be co-axial with the pinion 6. Each countershaft is divided into parts 12. 21 connected through a yielding coupling 25. The wheels 10, 16 may be of flexible laminations. A dynamometer may be used with each coupling to indicate the power transmitted. A suitable coupling is shown in Figs. 2 and 3, A member 29 on the shaft 12 has axial teeth 32 projecting between aligned teeth 35 on a boss 30 on the shaft 21. Spaces a allow axial movement. Plates 37 run right along each side of each axial row of alternating teeth, and are pressed apart by springs 36. The springs 36 of one coupling are set under greater pressure than those of the other couplings, so that the pinion 6 is thrust steadily in one direction for going ahead, and in another direction for going astern. A suitable dynamometer is shown in Figs. 2 and 4. Yielding of the coupling causes projections 42 on the member 30 to turn bellcrank levers 47 pivoted on the member 29. This operates a ring 41 axially. A fibre disc 50 can be moved into engagement with a groove in the ring 41 by turning an eccentric 52. Axial movement of the disc 50 is passed through a spindle 51 to a spring lever 55 having a long arm 56 moving over a dial 61.

Title: Improvements in or relating to current rectifiers
IPC: H02M7/00
Filed: 1931-10-22
Abstract: 391,792. Rectifying alternating current. SOC. ANON. HEWITTIC, and DEMONTVIGNIER, M. E., 11, Rue du Pont, Suresnes, Seine, France. Oct. 22, 1931, No. 29374. Convention date, Nov. 5, 1930. [Class 38 (ii).] A rectifier installation adapted to feed regenerative loads comprises a pair of oppositelyconnected mercury arc or other gaseous discharge valves associated with each phase winding of a single transformer 9. The valves 11 operate as rectifiers supplying D.C. to a network f from an A.C. supply 10. The oppositely-connected group of valves 12, 13, 14 is grid controlled and is adapted to operate as an inverter for returning energy to the A.C. supply when the D.C. voltage rises above the applied A.C. voltage. A choke coil 18 is inserted in the circuit common to the anodes of the one group of valves and the cathodes of the other. The effect of the voltage drop in the valves is overcome by adopting one or other of the following expedients: (1) the voltage at the terminals of the valves operating as inverters is increased with respect to the voltage at the terminals of the valves operating as rectifiers by the use of an auto-transformer 30, Figs. 4 and 6, (2) a battery or D.C. generator is used to augment the voltage at the terminals of the inverter valves, (3) the critical ignition voltage of the inverter valves is lowered so as to advance the moment of ignition thereof, (4) the critical ignition voltage of the rectifier valves is raised by introducing grid control so as to retard the moment of ignition thereof. Fig. 6 shows modified connections whereby six-phase rectification is used in combination with three-phase inverter connections.

Title: Improvements in or relating to coin-controlled vending machines
IPC: G07F17/32
Filed: 1924-12-08
Abstract: 248,114. Wade, H., (Mills Novelty Co.). Dec. 8, 1924. Delivery of articles stored in piles; premium checks, delivering.-In the apparatus described in Specification 246,621, means are provided for preventing the actuation of the premium check delivery-mechanism, when a similar check is inserted into the coin shoot. The slide, which closes the discharge passage for the checks, is connected by a stud 19, Fig. 5, to a lever 17 operable by a lever 21, which is actuated by the mechanism controlled by a governor as described in the prior Specification. The lever 17 is normally prevented from moving by the end 47<b>, Fig. 2, of a lever 47 which is connected by a slotted link 48 to a stud 49 on the arm 45 that actuates the releasing member for the rotary goodsejector. When the arm 45 is moved after the insertion of a coin the link 48 withdraws the stop 47<b>. A plunger 40 carried by a lever 39 abutsagainst the coin in the shoot 1 and is prevented from moving into the shoot under the action of a spring 42. The ends 39b of the lever 39 is thus not allowed to move into the path of the arm 45 and prevent the release of the vending-mechanism. If, however, a perforated premium check is inserted in the shoot 1, the plunger 40 passes through it and the end 39<b> of the lever 39 blocks the arm 45. thereby preventing the release of the goods delivery mechanism and the raising of the stop 47<b>. Indicators.-An indicator 53, Fig. 1, for showing how many checks will be delivered at the next actuation of the machine is associated with the pay-out slides 11 by means of a pinion 55<a>, segmental rack 56, links 56a, 58, and a lever 59 projecting beneath the slides 11. The bottom slide is always moved when a check is to be delivered to the discharge passage, and one or more superposed slides may be moved with it. The lever 59 is moved up by a spring 61 a distance corresponding to the number of slides displaced so that the dial 53 indicates how many checks have fallen on to the slide closing the delivery passage and are available on the next actuation of the machine by a coin. The lever 59 is reset bv a lever actuated bv an arm on the main rock-shaft.

Title: Improvements in electric converting apparatus
IPC: H02M7/54
Filed: 1924-12-10
Abstract: 248,117. Calverley, J. E., and Highfield, W. E. Dec. 10. 1924. Commutator switching- arrangements; polyphase transformers. - A polyphase primary circuit AA<1>, BB<1>, CC<1>, Fig. 1, is transformed by six three-phase transformers having cores 1 to 18 into a 36-phase secondary current, there being two oppositely wound secondaries on each core, and all the secondaries being connected so as to form a symmetrical closed ring, which is connected through a synchronouslydriven commutator to a direct-current circuit. As the primary current should be of sinusoidal form whereas the secondary should be of rectangular, there are in each transformer harmonics which should be neutralized. With each secondary winding there is associated a bye-pass circuit, all the bye-pass circuits being associated together so that the harmonics induced therein neutralize each other and thus these circuits offer very little impedance to the harmonics although they offer a large impedance to currents of fundamental frequency. In Fig. 4, the vector polygons P, S only partially shown, refer respectively to a delta connected primary and to the secondary, the members adjacent each vector indicating the corresponding core shown in Fig. 1, one of the commutator brushes being indicated as connected at this instant to the secondary winding on core 13. On each core there is inductively wound a bye-pass winding, these windings being connected to form six delta three-phase windings D, the apexes of which are connected by conductors L to six other delta windings E wound on a single three-phase transformer, the windings E serving to allow of the neutralization of the harmonics induced in the windings D. A synchronous motor M used to drive the commutator is connected to the system E, and by overexcitation it can be used to supply the whole of the magnetizing current of the system. A threephase supply N can be inductively associated with the windings E during starting and before tha gaps in the conductors L are closed by switches. Further, the whole alternating-current energy can be transferred to the system through this winding N and through the windings E and D to the main transformers, thus dispensing with the necessity of primaries on the main transformers. In a modification, the six inductively related delta windings E can be replaced by a single ring of conductively associated windings. In another modification, the bye-pass circuits are conductively associated with the main secondarv winding in which case tappings are taken between each of the thirty-six secondaries and connected to the equivalent of the transformer E. In some cases the windings of the transformer E can be placed upon the cores 1, 7, 13 of the main transformers. Specifications 140,853, 150,824, 150,825, and 184,259 are referred to.

Filed: 1970-06-20
Abstract: 1359468 Lubricating contacting interior surfaces of a tyre on deflation DUNLOP HOLDINGS Ltd 9 June 1971 [20 June 1970] 30034/70 Heading B7C A pneumatic tyre 1, which, when mounted on the wheel rim 2 for which it is designed and inflated, has an aspect ratio of between 30 and 75% and a tread whose width is greater than the distance between the tyre bead heels, comprises a coating of a lubricating material disposed on at least a part of the interior surface of the tyre to lubricate those parts of the tyre interior surface which contact when the tyre deflates under load, thereby to prevent tyre destruction due to frictionally generated heat and facilitate running of the tyre in the deflated state. The coating may be such as to withstand temperatures of at least 145‹ C. without deterioration of either the coating or its lubricating properties. The coating may be formed by incorporating a liquid, e.g. castor oil, which is insoluble in rubber, in a rubber liner 3 of the tyre, the liquid migrating to the exposed surface of the liner to form the coating thereon, there being a barrier layer 4 impermeable to the liquid between the liner 3 and the tyre carcass. Alternatively the coating may be particles of solid P.T.F.E., or a gel, applied directly to the interior surface of the tyre. The coating may, as shown in Fig. 1, be applied to portions A, D of the interior surface adjacent the beads and to portions B, C adjacent the tread edges, or may alternatively be provided over the whole of the interior surface. The thickness of the coating may be in the range 0À001-0À025 inch. The tyre may be a radial-ply tyre with a breaker assembly, or may be a cross-ply tyre. The wheel rim 2 which the tyre is intended to be used with has means to prevent the tyre from being dislodged from the rim when running deflated, which means may comprise a flat base on the rim, i.e. such that the rim is without a well into which the tyre beads can fall, as shown in Fig. 1, and/or a bead spacer ring or removable studs on the rim. The flat base rim may be divisible to permit tyre mounting and demounting, or may be a rim initially formed with a well which is closed up after the tyre has been mounted on the rim.

Filed: 1962-08-03
Abstract: 997,717. Printing plates. A. H. GRAY. Aug. 3, 1962, No. 30044/62. Drawings to Specification. Heading B6C. A flexible printing plate consists of a base of nitrile rubber and a printing surface comprising a thermoplastic synthetic resinous powder, based on vinyl-chloride vinyl-acetate copolymer resins, the base and the printing surface being fused together in the absence of any intervening adhesive. The image on the printing surface may be formed by projecting a negative, produced for example by a photographic process, on to said printing surface which is subsequently etched, or washed-out with water. A preformed sheet of a flexible thermoplastic synthetic resinous material based on polyvinyl resins may be placed between the nitrile rubber base and the printing surface and in order to prevent shrinkage of materials forming the plate a sheet of cotton or linen may be inserted between the preformed sheet and the rubber base. In the method of making such a plate the powder is placed in a mould and covered with the preformed sheet of flexible resinous material which in turn is covered by the base material, the three components being fused together in a mould under heat and pressure, without the use of any adhesive, the temperature range being between 140‹ and 165‹ C. and the pressure range between 450 and 1120 lbs. per square inch of mould area. In a particular plate for printing text pages only the printing surface consists of a thermoplastic synthetic resinous powder " VYNS-3 " based on vinylchloride vinyl-acetate copolymer resins. If desired, the powder may be dissolved and used as a paste or liquid. The surface material is covered by a sheet of thermoplastic synthetic resinous material " Vitrone A2KK " and finally an uncured nitrile rubber base is placed over the sheet before subjecting the assembly to heat and pressure. When it is desired to print material which contains half-tone and text the text portion of the printing surface may be powdered " VYNS-3 " whilst the half-tone area is of preformed " VR150 "-a vinyl-chloride acetate copolymer. Specification 911,222 is referred to.

Abstract: 1,211,588. Electro-photographic apparatus. INTERNATIONAL BUSINESS MACHINES CORP. June 24, 1968 [July 12, 1967; July 13, 1967], No.30072/68. Heading G2H. An apparatus in which latent electrostatic images are formed on a record medium by an image generator has a developing apparatus supplied with developer or a constituent thereof under the control of signals applied to the image generator. A cathode ray tube 3, Fig.1, produces an image on a uniformly charged drum 1 the latent image being developed by developer 7 supplied by a cascade developing apparatus 6. The developer 7 contains toner and carrier. The cathode ray tube 3 is supplied from a signal source 20. Toner feed signal means 25 are supplied with intensity and on/off signals along lines 24 and 26 respectively. The intensity signals are integrated in the means 25 and fed to a toner supply actuator 28 which controls the actuation of a toner supply hopper 30. The toner controlled may alternatively be liquid toner. The signal means 25 may be as described with reference to Fig.2 (not shown) in which the intensity signals are applied to a capacitor (41) which is charged as signals are applied to line (24). A transistor (52) conducts when the voltage on line (51) exceeds a predetermined level, thereby switching transistor (53) off. Pulses are applied along line (57) to a multivibrator (62). In a modification of the toner feed signal means 25, Fig.1, the head (H) Fig.3 (not shown) of toner controls sensing mechanism which actuates an arm (194) co-operating with a resistance (195) such that when the toner level is high a higher charge on a capacitor (141) will be required before toner replenishment is effected by an actuator (201). Instead of integrating signals supplied to the cathode ray tube individual signals may be counted by a counter (222) Fig.4 (not shown) which after a preset number of signals delivers a signal to a driver (224) which operates a relay (226). Relay (226) closes a circuit to an actuator (227) which controls a toner metering device (229). Signals may also be derived from a high speed printer Fig.5 (not shown) to control a toner distributer (236).
