Title: Improvements in and relating to electric circuit breakers
Inventor: FERGUSON ALEXANDER DALGETY
IPC: H01H47/14
Filed: 1950-06-09
Abstract: 688,487. Automatic circuit-breakers; protective cut-out arrangements. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 8, 1951 [June 9, 1950], No. 14468/50. Class 38 (v) A circuit-breaker for a traction-motor circuit has its contacts 9, 10, Fig. 1, normally maintained closed by an armature 35 co-operating with a holding magnet having a main exciting winding 67, 68, Fig. 2, and two controlling coils 79, 80, the coil 80 opposing, and the coil 79 assisting, the main excitation. The coils are connected in series with the motor circuit and at the ends thereof (see Fig. 4) so that an earth fault in the motor circuit 101, 102, 104 reduces the "assisting" excitation of coil 79 and enables the coil 80 to oppose the main winding 67, 68. The armature is released and the contacts are opened. The circuit-breaker of Fig. 1 has two pairs of series-connected contacts 9, 10, (one pair only is shown) each pair being provided with the arc-chute and magnetic blowout arrangement of Specification 478,824. The moving contacts 10 are carried by one end of a lever 32 which is pivoted at 31 and carries the armature 35 at its other end. The contacts are moved to the closed position by a piston in an air cylinder 6, the piston being provided with a tappet 54 which engages a roller 52 on the lever 32. The movement of the lever 32 against the tension of a spring 49 to close the contacts, brings the armature 35 into abutting engagement with the polar faces 36, 37 of the holding magnet, where it is held until a fault occurs as described above. The magnitude of the earth-fault current necessary to cause the opening of the circuit breaker is determined by means of a cylindrical magnetic member 84, which is axially adjustable in the air gap between auxiliary pole pieces 76, 77 carried by the limbs 69, 70 of the holding magnet, to alter the reluctance of the air gap. The supply of compressed air to the cylinder 6i s controlled by an electromagneticallyoperated valve 55 arranged so that after closing the contacts, the cylinder is vented to atmosphere and the piston retracted, so that the lever 32 is free to move when released by the holding magnet. As the circuitbreaker gives no protection against excessive overloads not involving an earth-fault, a line switch 105, Fig. 4, may be provided. The line switch 105 is controlled by an operating coil OC105 in a circuit including the normally-closed contacts (not shown) of an overload relay 106 and interlock contacts 57, 59, 57<SP>1</SP>, 59<SP>1</SP> operated by the circuit-breaker. The contacts 57, 59 are operated by the piston through linkage 63, 66, Fig. 1, and are closed when the piston is in its retracted position. The contacts 57<SP>1</SP>, 59<SP>1</SP> are closed by means of an abutment 32<SP>1</SP> on the lever 32 and a rod 56<SP>1</SP> when the contacts 9, 10 are closed. Thus the interlock contacts 57, 59, 57<SP>1</SP> 59<SP>1</SP> only permit the closing of the line switch 105 when the circuit-breaker is closed and is free to release.

Filed: 1956-05-10
Abstract: 799,087. Automatic guns. SCHWEIZERISCHE INDUSTRIE-GES. May 10, 1956 [May 13, 1955], No. 14583/56. Class 92 An automatic gun has a three part bolt assembly comprising a breech block 2 free to move relatively to a striker 4 and a striker guide block 5 which are urged apart by a spring 9; the breech block houses two locking bodies 14 which can enter recesses 15 in a casing 1 to lock the breech in the closed position, after which further movement of the guide block 5 causes a latch 17 temporarily to connect the breech block to the guide block. The striker 4 moves in cylindrical bores in the breech block and guide block and the relative movement of these three components is limited by a pin 11 on the breech block engaging in a slot 12 in the striker and by flanges 8 and 10 on the striker which abut on the ends of the guide block. On firing, a sear 23 is disengaged from the guide block so that a return spring 6 drives the bolt assembly towards the breech 25 thereby acquiring and loading a cartridge 24 in known manner. The breech block is stopped by the breech face, but the guide block and striker continue forward and arcuate faces 41 on the head of the striker force the locking bodies 14 out into the recesses 13. The striker is stopped when a firing pin 3 strikes the cartridge, but the guide block continues further forward so that the latch 17, urged by a spring 19, engages a catch 22 on the breech block. After firing, recoil force on the breech block is transmitted to the striker 4 which, due to the shapes of its head 27, of the recesses 13 and of the bodies 14, is caused to move rearwards against the springs 6 and 9 so that the shoulder 10 disengages the latch 17 from the catch 22 and the locking bodies are freed. The bolt assembly can then move back for a fresh firing cycle. The locking bodies 14 may be cylinders as in Fig. 4, balls as in Fig. 7 (not shown) or polyhedral plates as in Figs. 5 and 6 (not shown). In the latter instance the faces 41 on the head 27 of the striker must be flat and not arcuate.

Abstract: 1430652 Pneumatic conveyers LTG LUFTTECHNISCHE GmbH 28 March 1973 [29 March 1972] 14841/73 Heading B8A Articles conveyed through a duct by a current of air are delivered to a guide spaced from the outlet of the duct such that the conveying air had little or no effect to convey the articles further. In the figure, textile articles, e.g. stockings are placed in supply stations 10 and despatched at intervals through ducts 11 to common duct 15. The air current in duct 15 is produced by an injector 22 downstream of the supply stations. The articles leave the duct 15 under the influence of the air current and inertia and arrive after free flight at the guide means 30 leading to receiving station 19. The articles travel along guide means 30 by inertia and gravity, the force of the conveying air current having been dissipated at the outlet of duct 15. An alternative embodiment provides a mesh connecting the outlet of duct 15 and the guide 30 to prevent losses during free flight, and an opening in the latter part of guide to dissipate any remaining conveying air. A second alternative embodiment provides a shoot as the guide means (Fig. 4, not shown). The spacing between the outlet of the duct 15 and the guide means may be adjustable.
