Title: Improvement in anti-skid mechanism for master cylinder operated brake
IPC: B60T8/32
Filed: 1952-04-16
Abstract: 705,233. Fluid pressure brakes. WINGFOOT CORPORATION. April 16, 1952 [Sept. 28, 1951], No. 9565/52. Class 103(1) An anti-skid system for hydraulic brakes for aircraft having a brake disc 1 and brake cylinder 2 to which pressure is applied by a master cylinder 4 through a conduit 3 comprises a two-way valve 6 which is operated by a solenoid 7 when the wheels commence to skid so as to make the pressure exerted by a storage cylinder 9 effective upon the brakes and to reduce the pressure in cylinder 9 until skidding has been prevented. The solenoid 7 operates similtaneously with the valve 6 a threeway valve 12 of which the plunger 13 when moved to the left cuts off storage cylinder 9 from an hydraulic accumulator 16 and opens it to an exhaust port 17. As shown, the skid sensitive means for controlling the solenoid 7 comprise a polarity reversing switch unit 18 of known type having a shaft 19 driven from the disc 1, but a D.C. generator may be used instead. The unit 18, in the event of skidding, operates a current sensitive relay 32 and power relay 33 to energize the solenoid 7. To prevent the solenoid 7 being operated before the landing wheels are rotating, a micro switch 38, normally closed, is opened when there is a sufficient load on an undercarriage strut, thus de-energizing a slow release relay 34 included in the circuit. A relay 35 prevents the solenoid from being energized for longer than 30 seconds as may be caused by sticking contacts and on de-energization a warning lamp 36 operates. The circuit is put completely out of operation by a switch 37. A switch 52 and lamp 54 may be used for checking before landing. The hydraulic conduit 3 includes one-way valves 47 and 48, as shown, the latter by passing a plunger 49 with restricted flow passage contained within a cylinder 46. During a brake application, plunger 49 is forced upwardly so as to compress spring 50. When the brakes are released, however, the closing of valve 47 causes the plunger 49 to act as a dashpot so that subsequent applications produce a progressively diminished pressure at the brake 2 and thus reduce the frequency of the braking cycle.

Title: Improvements in or relating to circuit arrangements employing magnetic cores
Inventor: HUGHES EDWARD PIERCE
IPC: G11C19/04
Filed: 1957-03-27
Abstract: 854,105. Circuits employing bi-stable magnetic elements. AUTOMATIC TELEPHONES & ELECTRIC CO. Ltd. Feb. 19, 1958 [March 27, 1957], No. 9957/57. Class 40 (9). [Also in Group XIX] In a stepping register comprising magnetic storage cores with rectangular hysteresis characteristics, the output coil on each core is connected to the input coil on the next core by way of a coupling circuit comprising rectifying elements in the form of a D.C. biased saturable reactor or a pair of cores with rectangular hysteresis characteristics permanently operating in one remanent state, while the shift pulses are applied directly from a constant current source to the transfer circuits. In one arrangement, Fig. 3, two storage cores IMCA and IMCB have their respective output and input coils TC, IC interconnected by a coupling circuit comprising a saturable reactor IMCP continuously saturated by D.C. in a biased coil BC. Input and shift pulses are applied to coil IC on IMCA and to P4 in turn, and operation of the arrangement may be summarized as follows :- (1) The saturable reactor winding SC has a high impedance to the shift pulse current component 13 at all times. (2) When cores IMCA and JMCB register a " 1 " and " respectively both windings TC, IC present high impedances to currents 11, 12 and both core states are reversed. (3) When both cores are in state " 0," coil TC has a low impedance and provides a shortcircuit path for the shift pulse so that no change of core state occurs. (4) The saturable reactor winding SC provides a short-circuit path for induced current arising from reversal of a core state when information is entered in core IMCA or read-out from core IMCB. The arrangement, together with a further coupling circuit 2MCP, Fig. 5, comprises a single stage in the three-stage register shown in which coupling circuits IMCP, 3MCP, 5MCP and 2MCP, 4MCP, 6MCP are respectively subjected to alternate shift pulses P5, P6, the two shift pulses transferring an initial registration in core IMCA to core 2MCA before a further input pulse is applied. The shifting operation may be stopped at any time by reversal of the D.C. bias, while the direction of transmission through the register may be reversed by changing the bias and shift pulse polarities. According to the Provisional Specification, a modified circuit, Fig. 4, forms a complete stage in a six-stage register, Fig. 6, controlled by alternately applied pulses P8, P9, rectification in the coupling circuit being effected by cores IMCR and IMCS, each having rectangular hysteresis characteristics and operating permanently in one stable state. The operation is substantially the same as that in the Fig. 3 embodiment except that the permanent remanent state of the coupling circut cores must be reversed by a winding (not shown) to stop the register or reverse its direction.
