Patent GB-1418523-A (GB)
Title: Film processors
IPC: G03D3/12
Filed: 1973-10-31
Abstract: 1418523 Photo-electric sensing of coloured strips LOGETRONICS Inc 31 Oct 1973 50695/73 Heading G1A [Also in Division G2]  Film sheets pass through developing and fixing tanks (not shown) and a washing tank 1 and then either continue to a drying tank 2 or are diverted to a tray 36 e.g. so that litho film can be dot etched while still wet. Red or yellow strips (43), Fig. 3 (not shown) are stuck on to those sheets to be diverted. On leaving the washing tank 1, sheets pass through squeegee rollers 15, 16 and then pass a lamp 26. Light from lamp 26 passes through the film and is directed by mirrors 29, 30 on to photocells 32b, 32r through blue and red filters 31b, 31r. The output of photo-cell 32r together with the inverted output of photo-cell 32b are fed to an AND gate 47 if the sheet bears no coloured strip the inputs to the AND gate cancel. If a red or yellow strip is detected the gate receives only one input and produces a signal to energize a solenoid which shifts a guide 23 to direct the sheet through rollers 33, 34 on to tray 36. If guide 23 is not moved, the sheets pass through further squeegee rollers 17, 18 to drying tank 2.

Title: Sequential control systems
IPC: G05B19/045
Filed: 1972-11-03
Abstract: 1459177 Sequential control MACHINE TOOL INDUSTRY RESEARCH ASSOCIATION 1 Feb 1974 [3 Nov 1972] 50746/72 Heading G3N In a sequential control system, memory M1 stores, at each of its memory locations, an allowable combination of signals which may derive from a controlled machine or process, a corresponding location of memory M2 storing a combination of output signals to be generated in response to the particular combination of signals from the controlled machine or process. The latter signals are fed to comparator C, and a high frequency pulse generator P controls binary counter BC, addressing in sequence, locations of memories M1 and M2. When the content of the addressed location of M1 coincides with the combination of signals currently deriving from the machine or process, gate G is inhibited to stop the scan, the signal combination appertaining to the addressed location of memory M2 being fed to control the performance by the machine or process of the next step of the sequence. Consequent upon such step being performed, coincidence no longer prevails, and scanning recommences. During scanning, either the combination of signals from each location of memory M2 is fed to the machine or process, but at too high a rate to generate a response, or, alternatively, such signals may be inhibited from reaching the machine or process until scanning stops. An alternative sequence, defined by the content of the locations of memory M3 may be used, e.g. in emergencies. Each signal of the combination is a binary digit, which for feeding to the comparator, may derive from limit switches, and possibly include digits from controller operated push buttons or switches, and, to control the machine or process may, after amplification, operate valves, relays, or contactors. Sequences can be changed by alteration of the contents of the memory M 1  and M 3  locations. The memories may be of the read-only type, and may comprise magnetic core, or semi-conductor, units.

Abstract: 1390695 Testing earth-leakage circuit breakers S L RAMAGE 5 Nov 1973 51293/73 Heading G1U A device for testing an earth-leakage circuit breaker comprises means for simulating an earth leakage fault of a pre-settable amount (e.g 30mA) and means for indicating whether the breaker has opened within a selectable time period (e.g 30ms). As described the time period is related to the time taken for one of a set of rods 3, fig. I, to fall under gravity through a verticle tube 2 from an initial position in which its lower most end just blocks a lamp 4 from a viewing window 6, to final position in which the lamp just becomes visible, and the simulated earth fault is made at the instant an upper portion metallic portion of the rod-the lower portion being plastics-passes a sensor 7, 8. If the breaker opens sufficiently rapidly then the lamp 4 is extinguished before it becomes visible, whereas otherwise it is not and an observer will see some light from the lamp.

Filed: 1972-11-08
Abstract: 1398755 Semi-conductor pulse circuits ITT INDUSTRIES Inc 8 Nov 1972 [12 Nov 1971] 51447/72 Heading H3T Frame synchronizing pulses are extracted from a TV signal by integrating them (T1, T2, R1, R2, C1, C2) and line pulses removed by differentiating them. The circuit is said to permit smaller capacitors Cl, C2 to be used than hitherto. The composite line and frame sync. pulse signal (A, Fig. 2, not shown), is applied at A, and its complement at B. C2 is rapidly charged through T1 by the relatively longer pulses of the frame sync. signal, with a time constant R1.C1/B1 where B1 is the current gain of T1. The charge is held by the larger time constant R2.C2.B2, where B2 is the current gain of T2, until the end of the frame sync. pulses. The line sync pulses are differentiated by R1.C1. The output (D) appears at T2 emitter. Biasing is provided by R4, R5, and feedback optionally by R3. A diode connected transistor T3 effects temperature compensation. To suppress the remaining portions of the line sync. pulses in the output D, a threshold circuit may be used, such as a differential amplifier.

Title: Process for treating organic diisocyanates
IPC: C07C263/20
Filed: 1965-12-13
Abstract: In the manufacture of fibre-forming elastomeric polyurethanes by processes involving the addition of a solution of an organic diisocyanate to a polymeric diol, the diisocyanate solution is pretreated with an acid of the formula RCOOH, in which R denotes an alkyl radical of 1-3 carbon atoms, in a proportion of about 0.001-1%, based on the diisocyanate. The pretreatment nullifies the tendency for gel-formation to occur during the manufacture of the polyurethane.

Abstract: 1455137 Selective signalling SEISMOGRAPH SERVICE CORP 16 Nov 1973 [17 Nov 1972] 53394/73 Heading G4H A data transceiver can receive an incoming message containing respective tones for " 1 ", " 0 " and sync, a flip-flop being set and reset in response to detection of " 1 " and " 0 " tones respectively and feeding a shift register shifted in response to detection of the sync tones, detection of predetermined data in part of the shift register by a decoder causing other data in the register to be gated out, further data to be gated into the register and a clock to be started, the clock shifting the register out and controlling tone generator means also responsive to the shift register output to produce " 1 ", " 0 " and sync tones to form an outgoing message. One or more such transceivers can be used at each of a plurality of remote stations communicating over line or by radio with a central station which also has such a transceiver. Considering a transceiver at a remote station, the incoming message (from the central station) includes the address of a transceiver, frame bits and 4 command bits. If decoders recognize the address and frame bits, the command bits are gated out and, after a delay, frame bits and 12 data bits are gated into the register for transfer to the central station. The 4 command bits may control respective devices or go to one or more auxiliary modules (see below), and the 12 data bits may come from monitoring devices or from the auxiliary module(s). The possible auxiliary modules are an A/D converter module, an accumulator module and a multiplexer module, and various combinations of these can be used. The A/D converter module responds to the 4 command bits to select one of 10 analogue inputs to be digitized into a 12-bit count, the digitization being by integrating the analogue input while the counter is clock-driven to capacity, then continuing the counting of the clock pulses while the integrator voltage is reduced to zero using a constant discharge current, the count then being gated out. The accumulator module contains five pairs of channels for counting evenpulses, each channel having a pulse integrator and memory, followed by a pulse shaper (differentiator) followed by a 6-bit binary counter. The two counters of a pair of channels can be linked together to form a 12-bit counter. The 4 command bits select one of the pairs of channels and gate out their counts to give 12 data bits, the pulse integrator and memory of each channel being controlled to prevent pulse loss during gate out. The multiplexer module decodes the 4 command bits to, e.g. select one of a number of 12-bit inputs for passage to a 12-bit output, or reset counters in an accumulator module. The A/D converter module responds to different combinations of values of the 4 command bits than the accumulator module, to permit the two modules to be used together.
