Title: An arrangement for monitoring the operation of tap selector switches
IPC: B60L9/26
Filed: 1960-03-16
Abstract: 925,558. Control of A.C. motors. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. March 16, 1960 [March 23, 1959], No. 9281/60. Class 38 (3). [Also in Group XXXV] An A.C. traction motor is supplied through bus-bars from a transformer and controlled by a tapchanging mechanism which is monitored by detection of the voltage and current carried by the bus-bars to ensure correct opening and closing of the tap selector switches. Off-load selector switches 7, 8, 11, 12 are connected to bus-bars 5, 6, the currents in which are detected by current transformers 20, 21 connected to indicators or control mechanisms (not shown), which allow a switch to close only when no current flows in the bus-bar to which it is connected. The bus-bar potentials are detected by voltage transformers 15, 16 (or a single transformer connected between the bus-bars, Fig. 2, not shown), which indicate proper closing of a selector switch. The load current path may be divided into two parallel branches each tapping then being provided with two selector switches connected to separate bars 28, 29 or 30, 31. The current transformers 56, 57 and 58, 59 then indicate symmetrical current, loading in the pairs of bus-bars, and may be differentially connected to give zero reading under these conditions (Fig. 3, not shown). Two conditions must be satisfied before a tapping is opened: (a) there must be symmetrical current loading in the bus-bar systems; and (b) the voltage transformers must indicate proper closing of the subsequent selector switches. Transductors 54, 55 may be provided to reduce the current before switching so that on load switches 50, 51, 52, 53 operate substantially off-load and may be omitted.

Abstract: 905,080. Testing pressure in closed vessels. GENERAL ELECTRIC CO. Ltd. Dec. 21, 1960 [Jan. 6, 1960], No. 481/60. Class 106 (2). The pressure of a gas inside a closed frangible receptacle is determined by breaking the receptacle inside a hermetically-closed container using means operable from outside the container and observing the new pressure within the container by means of a pressureindicating device connected to the container. As shown, an electric lamp 16, of which the filling pressure is to be determined, is held firmly in holder 15 secured to a plate 1 by means of an apertured plate 17 and spring 21 inside an enclosing vessel 23 open at the bottom and pressed against a gasket 22 on plate 1 by a screw-clamp 24. The threaded rod 25 of the latter threadedly engages a bar 26 provided with keyhole slots 28 for engaging vertical bolts 27 mounted on the plate 1. The latter is carried by a framework 3 standing on a base 2 and has a small orifice leading via tube 4 and a three-way joint 5 to a mercury manometer 7. The system is sealed from the atmosphere by means of valve 11 and the pumping stem 32 of the lamp broken by a breaking member 33 carried by a spindle 34 extending hermetically and rotatably through the vessel wall 23 and provided with an arm 35 for manual rotation. Alternatively, the breaking member may be spring-loaded and held in constraint by a releasable catch; or it may be electrically operated. The scale 36 records either the difference of pressure before and after breaking, or it may be calibrated directly, for an apparatus of given dimensions, to indicate the initial pressure in the bulb.

Filed: 1964-01-06
Abstract: 1,089,432. Radio signalling. SERCK CONTROLS Ltd. Jan. 8, 1965 [Jan. 6, 1964], No. 490/64. Heading H4L. In a system for transmitting control and telemetry pulse signals between a master station and a slave station the master station comprises a microwave transmitter which is pulsed in accordance with the signals to be transmitted, a receiver for receiving similar pulse signals from the slave station, and means for reforming the received pulses to give a desired mark-space ratio, the slave station comprising a receiver for the pulses transmitted from the master station, means for reforming the pulses to give a desired markspace ratio, means for controlling equipment in accordance with the reformed pulses, and means for providing pulses indicative of the condition of the equiment for pulsing a microwave transmitter co-operating with the master station receiver. The transmitters (not shown) each include a magnetron or other microwave generator caapble of delivering pulses of about one microsecond duration and the arrangement at the receiver enables the duration of each pulse to be extended to provide unity mark-space ratio. As shown, in each receiver lengthening of the pulse is achieved by restricting the bandwidth at 1, due to the slow build-up and decay which takes place on the receipt of each narrow pulse, the noise bandwidth being correspondingly reduced. The output from 1 is integrated at 2 to give a further signal-to-noise improvement and the output of the integrator is squared and amplified at 4 to operate a flip-flop 4 providing coded output pulses of a width equal to the original pulses applied to the transmitter input. Feedback is supplied from the output of clipper 3 via shaping networks N to the input of clipper 3 and the input of integrator 2. To obtain a further signal-to-noise improvement pulses from a generator G1 inhibit receiver section 1 after the reception of each narrow pulse for a duration equal to the width of the reconstituted pulse and pulses from a generator G2 occur at the end of each reconstituted pulse and inhibit section 1 during the interval between the pulses.
