IPC: H01H9/44
Filed: 1960-11-11
Abstract: 940,511. Arc-rupturing in switches. I-T-E CIRCUIT BREAKER CO. Nov. 11, 1960 [March 18, 1960], No. 38750/60. Heading H2B. An air-break, magnetic blowout circuitbreaker has an arc chute divided into two sections and two blowout coils connected and arranged so that the fluxes generated by both coils in at least the first section are in aiding relationship. The circuit-breaker comprises movable main and arcing contacts 46, 50 cooperating with fixed contacts 48, 52 and an arc chute 58 having rear, mid and front runners 60, 61, 62, one blowout coil 70 being connected between the runner 60 and the fixed contact structure 40, and the other coil 84 being connected between the structure 40 and the runner 61 through a resistor 22. The magnetic structure 68 and the coils 70, 84 are constructed and arranged, Fig. 3 (not shown), in a manner similar to that of Specification 859,802, the coils being of the face-wound type. Upon opening an arc is formed between contacts 50, 52 and one end transfers to runner 60 so energizing the coil 70. The arc subsequently divides between runners 60, 61 and the runner 61 and movable arm 42, this division energizing the coil 84 and resistor 22 to enable the arc between runners 60, 61 to be extinguished by current transfer. Further movement of the arm 42 causes an arc to form between runners 61, 62, the resistor 22 limiting its current and the coil 84 causing its extinction. The coil 70 may be arranged as two series-connected coils 70a, 70b (Fig. 5) encompassing the chute area 80a, and the coil 84 as two series-connected coils 84a, 84b encompassing the whole chute area 80. In a modification, Fig. 6 (not shown), the coils 70a, 70b also encompass the whole chute area. The coil 84 may be made of high resistance wire to replace the resistor 22, in which case the coil turns are embedded in heat resistant insulation, Figs. 7 and 8 (not shown).

Filed: 1973-08-17
Abstract: 1389502 Data processing systems SPERRY RAND CORP 17 Aug 1973 [30 Aug 1972] 39024/73 Heading G4A A data processing system comprising at least one processor 10 (Fig. 2a), and input/output devices, one of which is shown in Fig. 2b, includes means for reserving an input/output device to a program being carried out by the processor. As described when the processor wishes to reserve a device it sends the device address to control logic 13a which then sends a signal on one of lines 19 1 -19 N , e.g. 19 1  to prime AND gates 23a-23d and 27 in the selected device. The contents of a register 21 are consequently fed on data lines 18 to a zero docoder 24. If the register 21 is in a clear state and the device is ready and on line one of AND gates 26 1 -26 N  is enabled to prime AND gates 22a-22d to enter a bit pattern for processor 10 into the register 21 to reserve the associated device. If the device has already been reserved for a different program, absence of a output from comparator 25 comparing the bit pattern sent by the processor with the contents of the register 21 results in NOR gate 29 applying a signal to circuit 51 to indicate to the processor that the device is already reserved. If the same program is required then the output of comparator 25 results in NOR gate 29 applying another signal to circuit 51 so that the processor is informed that the reservation has been successfully completed. The processor releases a device by sending a clear signal on line 20c. More than one processor may be associated with the input/output devices.
