Title: Door latches for automobile doors
Inventor: COVERLEY HAROLD ERNEST
IPC: E05B65/34
Filed: 1958-06-26
Abstract: 865,956. Latches. GENERAL MOTORS Ltd. May 27, 1959 [June 26,1958], No. 20508/58; Class 44. An automobile door latch comprises a toothed bolt wheel 4, a detent lever 5 which prevents rotation of the bolt wheel by engaging the teeth on it or on a separate ratchet wheel and a compression spring 32 lodged between the detent lever 5 and a lever 7 which is rockable by a push-button to rock the detent lever itself. As shown, the latch mechanism is mounted on a frame consisting of two plates 1, 2 approximately at right angles to each other, the plate 2 being mounted parallel to the inside surface of a door. The toothed wheel 4 is rotatably mounted on the inside of the plate 1 on a spindle 3 which carries on the outside of the plate 1 a toothed bolt (not shown). The detent lever 5 mounted on a pivot Band engageable at one end 6 with the wheel 4, engages at its other end 13 with a surface 12 on a link 9 which transmits to the detent lever 5, rocking movement of the push-button operated lever 7 mounted on a pivot A and by which the detent lever 5 may be freed from the wheel 4 against the spring 32. The arrangement is such that the angle subtended by the pivots A and B at the spindle C is less than 20 degrees. The inner end 10 of the lever 7 engages the link 9 through a hole 11 therein, and an end 17 of a lever 14 mounted on a pivot 14a is engageable with the end 10 of the lever 7 to permit the link 9 to be moved to free the lever 5 by an inside handle connected to the other end of the lever 14. A trip lever 18 mounted on a pivot 19 includes a flange 20 having a slot 21 for the passage of the end 22 of the link 9, the arrangement being such that clockwise movement of the lever 18 from the unlocked position shown, rocks the link 9 about the connections 10, 11 sufficiently to disengage the surface 12 from the end 13 of lever 5 thus rendering the push-button inoperative. The lever 18 is movable by a sill button or key-operated lock connected to a locking lever 24, 25 mounted on a pivot 26 and engaged in a slot 18a in the lever 18. The lever 18 is retained in either of two positions by an over-centre spring 31. A spring loaded lever 28 mounted on a pivot 27 returns the mechanism to the unlocked condition if the door is slammed, with the mechanism in locked condition, but without the push-button being depressed.

Abstract: 722,152. Cooling dynamo-electric machines. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Aug. 15, 1952 [Sept. 28, 1951], No. 20531/52. Class 35. Stator conductors are in insulating sleeves which also contain ducts for the passage of gas under a pressure differential equivalent to at least 3500 feet of the gas. As shown in Fig. 1, gas, preferably hydrogen, under pressure enters ducts in the stator and rotor conductor slots at both ends of the machines and at the centre is allowed to pass out into the central radial duct 7 in the stator core whence it flows to coolers disposed in the space between the stator core and casing. There may be two ducts per coil side as shown in Fig. 4, and spacers 20 may be placed at intervals so that the two ducts of one coil side are in communication along most of their length. In a modification, a partition is placed between the stator and rotor, the rotor cooling being as shown in Fig. 8, a cooler 61 being placed at each end of the machine, while the stator may have a blower drawing gas from the centre of the outer stator core periphery and passing it over a cooler in the machine base before returning it to the two ends of the stator conductor slots for axial passage to the centre. Two stage fans may be used on the rotor shaft, and additional blowers may be used at intermediate parts of the gas stream to increase the pressure. The rotor conductors may be hollow or U-shaped. Specification 722,151 is referred to. Reference has been directed by the Comptroller to Specification 682,340.

Abstract: 658,600. Air-blast switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Aug. 8, 1949, No. 20554. Convention date, Aug. 9, 1948. [Class 38(v)] To enable the supply of compressed air to an air-blast switch to be reduced immediately after the arc has been extinguished, the switch 1 is supplied from a container 8 through blast valves 9 arranged in parallel in the air supply system, one of the valves remaining open after the others have automatically reclosed. When the switch is opened the operating solenoids 12, 13 of the valves 9 are are energized and the valves open simultaneously. Compressed air is supplied to the air-blast switch 1 through the blast pipe 10 and through a pipe 18 and chamber 17 to a cylinder containing a piston 16. After the slight delay imposed by the chamber 17 the piston 16 opens contacts 15 to interrupt the current to the two lower solenoids 12. Hence the two lower valves 9 reclose whilst the uppermost valve remains open to permit a small supply of air to the switch to prevent reignition of the arc. An isolating switch 4, 6 may be provided.

Abstract: 942,501. Electron beam apparatus. BURROUGHS CORPORATION. June 7, 1961 [June 21, 1960], No. 20605/61. Heading H1D. A trochotron beam switching tube has a central cathode 16, spade electrodes 18, target electrodes 26, switching electrodes 28 and auxiliary, as shown L-shaped, electrodes 30 which serve (a) to shield the switching and target electrodes from each other, and (b) to collect excess electrons from the beam when the target potential falls to too low a level for the target to collect all the electrons. The latter effect prevents spurious switching. The target electrodes 26 may be permanent magnets to provide the necessary longitudinal magnetic field. Switching potentials may also be applied to the auxiliary electrodes 30 or output signals derived from them or each auxiliary electrode may be connected to the spade electrode of an adjacent electrode group for improved stability of operation.

Title: Improvements in or relating to motor control arrangements for printing telegraph receivers
Inventor: POULTER THOMAS GEOFFREY
IPC: H04L12/12
Filed: 1947-07-31
Abstract: 644,053. Copying telegraphy. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 31, 1947, No. 20842. [Class 40 (iii)] In a copying telegraph system of the Hell type in which the printer motor is started by a mark signal and stopped by a longer mark signal the motor control circuit comprises a first slowrelease relay energized when the receive relay is in its normal spacing condition, a motorcontrol relay having an operating and a locking winding energized by the release of the first relay to start the motor, and a delay relay energized upon energization of the first relay and having contacts which break the operating and locking circuits of the control relay and also its own energizing circuit. When a long starting mark is received the receive relay 21 opens contacts 23 which release a first relay 24 after 250 ms. delay. Contacts 26 then close and energize the operating winding 27a of a motorcontrol relay. The motor 10 is started over contacts 29 and the control relay is locked over contacts 28. If a longer mark, or stop signal, is now received, the first relay 24 again releases and completes the circuit of a thermal or other long delay relay 211 and after being energized for, say, 10 seconds its contacts 212 open, breaking the locking and operating circuits of the motor-control relay and so stopping the motor 10. The contacts 212 also break the circuit of the thermal relay 211 so that if the stop signal persists the relay does not overheat and will alwavs release within 20 seconds of being operated, ready to receive a further start signal. The release of the first relay 24 is delayed for 250 ms. by a condenser 13 in order to prevent false starting by noise.

Abstract: 702,491. Hydro - mechanical variable - speed gearing. GAUTIER, J. H. Sept. 7, 1951 [Sept. 22,1950; Jan. 3, 1951], No. 21140/51. Class 80 (2). Variable-speed gearing between driving and driven shafts 1, 2 comprises a hydraulic torque converter having impeller blades 4 rigid with shaft 1, first turbine blades 5 rigid with a shaft 13 carrying sun gears 14, 15 of first and second epicyclic trains, second turbine blades 6 rigid with a sleeve 20 connected through a clutch 21 to a second sun gear 25 of.the first train the stepped planets 27 of which are carried by a second sun gear 31 of the second epicyclic train the stepped planets 33 of which are carried by the shaft 2, and reaction blades 7 rigid with a gear annulus 40 meshing with planets 41 carried by a member 44 and meshing with a sun gear 42 on sleeve 20. A one-way detent 45 prevents reverse rotation of member 44, a one-way clutch 43 allows reverse rotation of annulus 41 relative to sleeve 20, and a one-way clutch 18 prevents shaft 13 from overrunning shaft 1, whereby reverse rotation of sleeve 20 is prevented while the reaction blades 7 can rotate forwardly only up to the speed of sleeve 20 and can rotate reversely only up to a fraction of the speed of sleeve 20. With clutch 21 engaged, the speed of shaft 2 depends on the difference between the speeds of blades 5 and 6. At starting, shaft 2 is driven at minimum speed by the blades 5 through the epicyclic trains, sleeve 20 and annulus 41 being stationary. Turbine 6 then begins to drive, this being facilitated by notches 51 at the inner-periphery of the inlet ends of the blades 6, thus increasing the speed of shaft 2. At this time, the blades 7 are rotating reversely. As the speed builds up, blades 7 begin to rotate forwardly, until the transmission reaches a direct-drive condition. By disengaging the clutch 21 and applying a brake 24 to gear 25, a fixed reduced forward drive from shaft 13 to shaft 2 is obtained. Exterior blades 55 rigid with blades 4 co-operate with inlet holes 56 to replenish the luquid in the converter. Additionally, as shown in Fig. 15, a clutch 127 is provided between the carrier 30 of pinions 27 and sun 31, a free annulus 137 meshes with pinions 33, and a free sun gear 146 meshes with an additional step 147 of pinions 33. If, with clutch 127 disengaged, a brake 140 is applied to annulus 137, shaft 2 is driven from shaft 13 at a fixed reduced speed, but 'higher than that produced by brake 24, while, if a brake 143 is applied to sun 146, a fixed reverse speed is obtained.
