Title: Control method using computers operating in parallel
IPC: G06F11/00
Filed: 1974-01-22
Abstract: 1444513 Data processing system INTERNATIONAL STANDARD ELECTRIC CORP 22 Jan 1974 [26 Jan 1973] 02852/74 Heading G4A A data processing system used, e.g. to control a railway signalling system, comprises at least two redundant computers and, in normal operation, is arranged such that an output from a second one of the computers is fed to a first one of the computers for comparison therein with the output developed by that computer, if the comparison produced agreement the output is read into an output register from where it is read to the second or in the case where there are three computers, the third computer for comparison therein with the output of that computer, and if the comparison produces agreement the contents of the output register are gated as an output of the system. As described three computers R1, R2, and R3 normally operate in a triple redundant fashion and are assigned the functions of an output computer R1, a comparator computer R2, and a read back/check computer R3, any of the computers being able to perform any of the functions. Output computer R1 receives an output T2 from comparator computer R2 and compares it with its own output T1. If the outputs match the comparator computer output T2 is fed to output register A-Reg. If the outputs do not match R1 compares the output of R3, i.e. T3, with T2 and T1. If T2 and T3 or T1 and T3 match, T3 is fed to output register A-Reg, T1 or T2 being declared "erroneous" as appropriate. If none of the outputs match an alarm and interrupt are generated. Assuming T2 has been fed to A-Reg the contents of A-Reg are fed to read back/check computer T3 where they are compared with T3. If the comparison produces a match computer R1 is signalled and R1 enables the transmission of the contents of A-Reg, i.e. T2, to the system output. If the comparison does not produce a match R3 compares the contents of A-Reg with the outputs of R1 and R2, i.e. T1 and T2, received over lines L13 and L23. If the comparison produces a match R3 declares itself "erroneous" and enables the transmission of the contents of A-Reg to the system output. If the comparison does not produce a match R3 compares T1, T2, and T3 and if they all agree writes the result into -A Reg and repeats the read back check. Operation with only two computers, one performing the functions of the comparator and read back/check computers and the other that of the output computer, is described for when one computer continually differs from the other two, this computer being disconnected. It is stated that each output word from each computer may consist of like ordered bits from a plurality of control words, the control words being accumulated in appropriate controlled devices. The computers are arranged periodically to exchange and compare test data to determine if any are faulty. The computer outputs may be coded for error detection.

Abstract: 1,140,231. Electromagnetic clutches or brakes. POTTER INSTRUMENT CO. Inc. 24 Jan., 1966 [9 Feb., 1965], No. 3163/66. Heading H2A. A clutch comprises a cylindrical housing 16, 18, mounted on bearings 32, 34 on the output shaft 30 and driven, pulley-fashion, by a belt connected to a prime mover. An annular rotor chamber in the housing communicates with the clearance between housing and shaft and is occupied, with small clearance, by a disc-shaped rotor 66 secured to the shaft. A labyrinthine seal structure 70, secured to the housing in the clearance between housing and shaft on either side of the rotor, prevents loss of magnetic powder mixture; the seal structure is filled with a plastics material. A further annular chamber radially beyond the rotor chamber, houses two coils 52, 54; one end of each coil is connected to a printed conducting ring 90 or 94 on an insulating board 86 secured to one end of the housing; the other two ends of the coils are both connected to a third conducting ring 92 on the board. Preferably the rotor is perforated, and has roughened faces, to improve the clutching action. Preferably one end of the shaft 30 is half cut away for engagement with a similarly-shaped brake shaft 45 located in a brake mechanism which is identical with the described clutch except that the housing is fixed. In operation, the inner coil 52 is supplied with a pulse, and then a lower steady current, to rotate shaft 30. The clutch is thereafter disengaged rapidly by switching off the current to coil 52 and applying an opposite current pulse to coil 54. The coils of the brake mechanism are de-energized and energized appropriately. The apparatus is intended for high-speed intermittent rotation of a magnetic-tape capstan at, e.g. 100 times per second.

Title: Improvements in hydraulic shock absorbers
IPC: A44B9/18
Filed: 1937-02-03
Abstract: 475,614. Hydraulic shock-absorbers. GENERAL MOTORS CORPORATION. Feb. 3, 1937, No. 3165. Convention date, Feb. 3, 1936. [Class 108 (iii)] A hydraulic shock-absorber comprises two displacement chambers and an inertia mass 103 adapted through the medium of a togglejoint member 112 to actuate selectively one or other fluid control devices 72, 84 to restrict the flow from one or the other of the chambers in accordance with the direction of the accelerative movements of the shock-absorber. As shown diagrammatically in the Figure, a casing 30 is provided with hydraulic cylinders 50, 51 containing pistons 40 operated respectively by a cam 37 on an up or down movement of the vehicle axle. When the wheel rises to pass over a bump in the road the piston 40 in the cylinder 50 is forced inwardly and the liquid therein is forced through a passage 60 and spring-loaded control valve 64 to a passage 65 and thence through chamber 66, under valve 72, passages 75 and 91 to chamber 90 which is in communication with liquid reservoir 31. Excess pressure in the chamber 50 passes to the reservoir through spring-loaded relief valve 48 in the piston. Similarly when the wheel descends piston 40 compresses the liquid in cylinder 51 which escapes through passage 98, spring- loaded control valve 97, passage 93 to chamber 82 and thence under valve 84 and passage 91 to chamber 90. Additional resistance is provided to the flow from cylinders 50, 51 by the closing of valves 72, 84 operated by tongues 113, 114 on a plate 112 pivoted at 111 to a casing 102 which is pivoted at 101 to the reservoir casing and supports inertia masses 103. The points 113, 111, and 101 and 114, 111, 101 form three points in a toggle system, the point 111 aligning with the points 101, 113 or 101, 114 in accordance with a rise or fall of the inertia mass 103 due to a rapid acceleration in a downward or upward direction. When the chassis has a rapid downward acceleration the piston 40 forces liquid out of chamber 50 and past control valve 64 to passage 65 and under valve 72, but this valve has now moved toward its closed position due to the inertia mass 103 rising and thereby tending to align points 113, 111, and 101. The How of liquid from cylinder 50 therefore is additionally restricted and the rapid movement of the chassis absorbed. On an upward acceleration of the chassis the inertia mass 103 moves downwardly with a consequent closing of valve 84. The inertia mass is supported on a spring 104 and is connected to a dashpot to prevent chattering.
