Title: Improvements in or relating to equipment for reading out groups of digital data stored in a plurality of registers
IPC: G11C19/00
Filed: 1960-10-31
Abstract: 966,262. Telegraphy. GENERAL ELECTRIC CO. Ltd., and G. H. PELLS. Sept. 28, 1961 [Oct. 31, 1960], No. 37403/60. Drawings to Specification. Heading H4P. In a data storage and read-out equipment groups of digital data received over three landlines are stored in three corresponding shift registers. The three data groups overlap in time, and, due to differential delays, more than one of the registers may become full simultaneously. The present invention provides a way of reading out the data from the registers in the correct order. Upon a register becoming filled with a group of data signals, a signal is generated which initiates read-out from that register to a buffer register. However, if two or more registers become full simultaneously, the signals generated actuate a priority system comprising a number of gates and bi-stable triggers, whereby the registers are read out in the correct order. Full details of the manner of operation are given in the Specification.
Patent GB-1281789-A (GB)
Title: Improvements in and relating to conveyor arrangements
IPC: G03B27/16
Filed: 1970-08-04
Abstract: 1281789 Shaft couplings RICOH KK 4 Aug 1970 [14 Aug 1969] 37473/70 Heading F2U [Also in Division G2] In a photocopying machine in which copy sheets are carried through an exposure station by an endless belt, means are provided for detecting stoppage or slipping of the belt and causing this to produce a signal. Fig. 1 (not shown) is a conventional arrangement in which an original and copy sheet are carried in contact round a printing cylinder (7a) within which is a light source, the sheets then being separated and the copy passed on to an ammonia developing section. A cooling fan (15) is also provided. The belt passes over a number of guide rollers, one roller 3 having a shaft 3a which is journalled in a bearing 16 supported in a side plate 17 of the machine. Shaft 3a carries a coupling 18 which engages a cam plate 19 through a one-way clutch 20. A second cam plate 21 closely adjacent plate 19 is also connected by a one-way clutch 22 to a shaft 24a of a motor 24. The speed of shaft 24a is selected to be such that it is lower than the lowest normal operating speed of shaft 3a. A pin 25 on cam plate 19 engages in an arcuate slot 26 in cam plate 21, and since normally plate 19 is rotating faster than plate 21 the relative positions of pin 25 and slot 26 is as shown in solid lines in Fig. 3. If slippage or stoppage of the belt occurs, the speed of shaft 3a falls below that of shaft 24a. Thus, instead of plate 19 driving plate 21, plate 21 will drive plate 19, the relative positions of pin 25 and slot 26 now being as shown in brokenlines. Plate 19 has a recess 27 in its periphery, and plate 21 a similar recess 28. Normally, these recesses are out of register, so that a roller 30a at the end of a switch arm 30 rides along the periphery of the plates 19, 21. When the speed of plate 19 drops, so that it is being driven by plate 21, the two recesses will come into register, so that roller 30a will now drop into the recesses, thus causing switch 29 to operate. This is arranged to shut off the light source and the motor driving the belt.

In an arrangement for generating a substantially sinusoidal voltage having, a predetermined phase relative to a reference voltage and an amplitude dependent on that of a control voltage, a voltage of rectangular waveform, Fig. 1, is developed in which alternate periods of positive and negative value each of one-third of a cycle are equally spaced and the desired output is derived through a filter circuit. Onoff switches S1-S4 in the network, Fig. 2, are cyclically controlled as shown in Fig. 6 (a) and produce at the junction of resistors R1, R2 from the voltages +V and -V at terminals IT1, IT2 the waveform of Fig. 1 of negligible third harmonic content. The voltages V are equal and opposite and are controlled by a control signal. The on-off switches which may be the rectifier arrangements described with reference to Figs. 3-5 (not shown) may be fed from a three-phase supply through a Scott transformer arrangement to obtain the desired phase relationship.

Abstract: 1403081 Diaphragm pumps BRITISH PETROLEUM CO Ltd 15 Aug 1972 [27 Aug 1971] 37943/72 Heading F1A [Also in Division G4] In a diaphragm pump comprising a diaphragm 3 reciprocated by a solenoid 37 energized by a train of actuating pulses, groups of the pulses are suppressed to reduce the pump output. The pump inlet and outlet valves 8, 9 are operated by solenoids 38, 39. Five consecutive pulses of the train cause the pump to perform one working cycle, i.e. open inlet (11), Fig. 2 (not shown) draw in diaphragm (12), close inlet (13), open outlet and push out diaphragm (14) and close outlet (15). Thereafter a group of pulses (19) is omitted before the next cycle of the pump. Several pump cycles may be performed between each interval (19), in which case control of the pump output can be either by changing the number of pump cycles or the length of interval or both. In Fig. 3 (not shown) the total number of pump actuating pulses is divided between two pumps in a desired ratio in a petrol blending dispenser.
