Patent GB-753403-A (GB)
Title: Improvements in electrical circuits for timing a sequence of operations
IPC: H04N7/10
Filed: 1954-06-15
Abstract: 753,403. Timing control systems for resistance welding. WELDING RESEARCH, Inc. June 15, 1954 [June 15, 1953], No. 17575/54. Drawings to Specification. Class 38 (4). The timing of a sequence of operations, such as required in resistance-welding, is effected by a number of multi-cathode cold counting tubes (one for each operation) which are rendered operative in sequence and time their respective operations by counting cycles of an A.C. control voltage, preferably the mains supply voltage feeding the welding apparatus. Each counting tube has an associated discharge valve which, when conducting, causes the control voltage to be applied to (and its cycles counted) its counting tube, together with the transmission of resetting pulses to the other counting tubes to prepare these for later operation. After a predetermined count, corresponding to the desired time of the operation, the counting tube transmits an initiating pulse to the valve associated with the next counting tube, that valve becoming conductive and causing the control voltage to be applied to the next counting tube, which thus commences to time the next operation. The counting tubes thus become operative in turn as the sequence proceeds. The several discharge valves are interconnected by a commutating circuit, so that initiation of conduction in one valve applies an extinguishing potential to all the others and thus only one counting tube can be in operation at a time.

Abstract: 800,638. Magnetic recording and reproducing apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 7, 1956 [June 10, 1955], No. 17633/56. Class 40 (2). A magnetic record apparatus employs detachable cassettes containing spools driven by means of friction wheels 19 provided in the cassettes in proximity to their edge and brought into and out of engagement with a driving-shaft 3 or 6 by the tilting of the cassette about supports constituting a tilting axis. The cassette 10, which is insertable into an opening 2 in the apparatus, contains turntables 17 frictionally coupled to supply and take-up spools carrying the record tape 21 which passes from one spool to the other over guide pulleys 23 and a roller 14 supported between ears 13 acting as a guide for the tape. The friction wheels 19 are coupled to the turntables 17 by belts 20. The cassette is provided with domes 12 which engage sockets 7a in the supports 7 and form the tilting axis for the cassette, which is held in the neutral position, shown in Fig. 2, by spring arms 8 which engage notches 9 in the cassette. A normal forward drive is effected by tilting the cassette to the right, as shown by the chain-dotted position in Fig. 2, in which position tape 21 is gripped between the driving capstan shaft 6 and one of the wheels 19 whereby the tape is drawn across the erazing head 4 and record/reproduce head 5, in which position the cassette is held by the engagement of the springs 8 with further notches 9a. A fast rewind is effected by tilting the cassette back through the neutral position until the tape 21 is gripped between driving roller 3 and the other wheel 19, in which position it is again held by springs and notches (not shown) on the other side of the cassette. A fast forward drive may be carried out by removing the cassette and replacing it in the reverse position and again tilting it to the left. Means indicating the amount of tape on a particular spool is provided by a pointer 26 pivoted at 25 and drawn across a scale 38 by a duplex slotted arm 30 pivoted at 29 and having a pin 31 which engages the surface of the tape on one of the spools.

Filed: 1957-06-06
Abstract: 822,099. Measuring short time intervals. ALLEN ELECTRIC & EQUIPMENT CO. June 6, 1957, No. 17982/57. Class 37. To measure the ratio of the time contacts are open and closed of a regularly operated circuit breaker, the oscillations developed when the contacts 13 are opened are rectified and applied to prevent current flow through a meter, current flow being allowed when the contacts are closed, so that the average reading of the meter indicates the desired ratio. When the contacts are closed there is no appreciable voltage across terminals 23, 26, and current will flow through resistances 21, 19, rectifier 34 and meter 32, but when the contacts are open a voltage, initially including oscillating pulses, will appear at terminals 23, 26. This voltage always exceeds that of 29 by reason of the source 11, and by reason of rectifiers 17, 18, it is always of opposite sign so that rectifiers 34, 41 ensure that the meter 32 receives no current during the whole time contacts 13 are open. In a modification, Fig. 4, the meter circuit includes a gating valve 40 which is rendered non-conducting during the whole time the contacts are open by the rectifier bridge 16.
