Title: Improvements in and relating to electric control systems and apparatus therefor
IPC: H01H83/12
Filed: 1928-08-03
Abstract: 295,045. British Thomson-Houston Co., Ltd., (Assignees of Townsend, G. R.). Aug. 5, 1927, [Convention date]. Controllers with no-volt release, electromagnetic.-A motor 10 which is started under the control of any of the push-button switches 13, and stopped by operating any of the pushes 19, is disconnected from the supply on occurrence of low-voltage and is re-connected automatically if the normal voltage is restored within a given time period of such a duration that the motor would not have come to rest. Upon operation of any switch 13 of the contactor 12 picks up and at contacts 22 completes the circuits of coils 15 which cause series connected contacts 17 to close immediately, the racks 20 moving freely over ratchet pinions 21, and thereby establish a maintaining circuit for the contactor 12. Upon the occurrence of low-voltage, the contactor 12 immediately opens, and the coils 15 are de-energized, the racks 20 fall slowly, being retarded by escapement wheels 18. If normal voltage is restored before the contacts 17 open, the contactor 12 recloses, but if the contacts 17 have opened, then the contactor can only be re-closed by pressing one of the switches 13. Upon operating any push 19, the corresponding contacts 17 is opened and the rack 20 is moved out of engagement with the ratchet pinion 21 so that this rack falls without any time delay and thus the motor is stopped. One of the time delay switches is located adjacent each starting push button 13. In a modification, the push buttons 13 are in series with the coils 15 and the contacts 17 are in series with the coil of the contactor 12, the contacts 22 closing a maintaining circuit for the coils 15. The mode of action is similar to that of the first system.

Abstract: 934,333. Brakes. P. B. FONDEN, and K. O. T. WALANDER. June 15, 1962 [July 10, 1961], No. 23167/62. Class 103 (1). [Also in Group XXXIII] A braking device connected to the rope or net of an aircraft arresting gear comprises a wheel having braking pads co-operating with a surface in a channel alongside of the runway. Fig. 2 shows a cross-section of one device, in which a rope 4 is connected to a non-rotary shaft 7 supporting a wheel 5 which runs along a ledge 6 of the channel and is thereby rotated. Part of the wheel periphery lies in a groove in the channel, and passages 15 connect a plurality of circumferentially spaced pairs of brake pads 10 alternately to pressure and exhaust chambers 12, 16 in non-rotary shaft 7, so that as each pair of brake pads enters the groove, pressure fluid is fed to that pair to press the pads against the groove, and as the pads leave the groove, they are connected to the exhaust chamber 16. A centrifugal device 14 operates a valve in the pressure feed duct so that braking ceases when the wheel speed drops to a predetermined value. Guide wheels 8 on shaft 7 co-operate with the channel walls. In an alternative, Fig. 4, the pads of a pair face each other across a groove in the wheel, and grip a ledge on the channel between them. Opposite this ledge, a metallic fin 18 penetrates the groove, to assist in cooling the pads. The brake pads may be fixed in the wheel, being in the upper surface thereof, the moment of the rope on the wheel applying the pads against a ledge on the channel. In a further embodiment, Fig. 8, the pads are fixed in the wheel, and run in a groove formed between a ledge in the channel and members 20 adjustable by fluid pressure devices 21. The height of members 20, and thus the degree of braking, can therefore be varied along the channel. Part of the rope may initially be wound on a drum connected through a brake and one-way clutch to the wheel, so that the braking device is accelerated gently when the aircraft engages the rope. The drum may be conical.

Abstract: 533,709. Fuel-injection pumps. DAIMLERBENZ AKT.-GES. Aug. 14, 1939, Nos. 23398 and 23399. Convention dates, Aug. 13, 1938 and June 10, 1939. [Class 102 (i)] In a pump comprising a main piston 2, and an accumulator piston 3, the pistons are formed with machined end surfaces 12, 13 which come into intimate contact at the end of the delivery stroke and thereby expel all air or vapour, accumulation thereof in the system being thereby prevented. Preferably the piston 2 is actuated by a cam 4 and spring 5, and the piston 3 is actuated during the delivery stroke by weak and strong springs 6, 9. The piston 3 is formed with a collar 7 which abuts on the spring 6 and an adjustable stop-nut 8, and the spring 9 abuts on a collar 10 which rests on the cylinder 1. Fuel enters the space 14 through a passage 15, and when the piston 2 rises, the piston 3 is raised in opposition to the spring 6 and then in opposition to both springs 6, 9. The piston 3 then delivers fuel through a passage 16, delivery ceasing when the end surfaces 12, 13 of the pistons come into intimate contact. The double spring 6, 9 may be replaced by an equivalent spring, for instance, a spring of inverted conical shape. When a feed-pump is employed, the inletpassage 15 is provided with a non-return valve and is formed with a wide mouth, the pistons being arranged to separate opposite the mouth at the beginning of the suction-stroke. The arrangement prevents formation of vapour in the inlet passage, particularly when very light fuels are employed. The non-return valve may be omitted. The Specification, as open to inspection under Sect. 91, comprises also-means for placing the space between the pistons in communication with a relief-passage for the purposes of suddenly terminating delivery. This subject-matter does not appear in the Specification as accepted but now forms the subject-matter of Specification 537,772.
