Title: Improvements in circuit arrangements for detecting or indicating the opening of an electric switch
Inventor: CRAXTON ROBERT TREVOR
IPC: H02H3/04
Filed: 1955-02-03
Abstract: 801,276. Protective arrangements. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 30, 1956 [Feb. 3, 1955], No. 3236/55. Class 38 (5). In an arrangement for indicating the opening of a switch connected in series with other switches, a branch including an electric discharge device in series relationship with the switch is connected in shunt to one portion of a potential divider, the circuit characteristics being such that a discharge in the device initiated with the switch closed is maintained while the switch remains closed and is interrupted when the switch is opened. The switches may comprise the contacts C1 ... C4 of overload relays, the contacts being connected in series with the coil CB of a circuit-breaker across a D.C. supply. Neon diodes D1 ... D4 in series with resistors P1 ... P4 are connected between the contacts and the junction T between resistors R1, R2 forming the potentiometer. When all the contacts C1 ... C4 are closed, the momentary depression of a push-button switch S short-circuits the resistor R2 and full voltage is applied to the diodes D1 ... D4 causing them to strike, the glow of the diodes indicating normal operating conditions. Should, for example, contacts C3 open, then the polarity of the voltage across diode D3 and any following diodes, i.e. D4, is reversed momentarily, the diodes D3, D4 extinguish and remain extinguished, even though the contacts C3 may reclose, as the voltage across the diodes is not sufficient for striking to occur until the switch S is pressed. Reference is made to the use of the arrangement in detecting the faulty operation of a series contactor system.

Title: Swimming pools
IPC: F24S90/00
Filed: 1975-04-24
Abstract: 1502416 Swimming pools B R CARTER 24 April 1975 [24 Jan 1974] 03389/74 Heading A4N A swimming pool arrangement for circulating and heating water comprises a pool basin 1, a terrace 3 adjacent the basin and inclined downwardly towards the basin, a reservoir tank 4 adjacent the terrace, and a pump 13 in a conduit leading from the basin to the tank, the arrangement being such that either water is released through the large valved outlet 17 of the tank and floods the terrace to allow a buoyant, thermally insulating cover 15 to be floated out on to the pool to reduce heat loss therefrom or alternatively water is released through the small valved outlet 24 and heated by solar energy as it flows over the terrace from where it is channelled through apertures 8 in wall 6 into gully 7 and thence via conduit 9 to the bottom of the basin, the water returning to the tank via conduits 10 to 12 and pump 13. When the pool is not in use water may be heated by setting valve 23 to allow flow from conduit 22 to the pump and setting valve 21 to direct flow from the pump to the tank so that water flows from the tank over the terrace, down the gully, through conduits 9 and 22, and back to the tank via the pump. Filtering is provided by filters 18 and 19 and may take place without heating the water by setting valves 21 and 23 so that water is withdrawn from the pool through conduits 10 to 12, passed through filter 18 and pump 13 and returned via conduit 20. The water may be heated by passing it over an opaque cover, under a transparent cover, or between one of each type of cover, the cover being attached to the tank by, for example, hooks and eyelets. Alternatively in addition the water may pass through pipes in the terrace. The terrace is preferably formed of a heat insulating material covered by a durable waterproof material. There may be optionally a multiple arrangement of terraces, tanks, covers and conduits. A weir or channel may be provided between the tank outlets and the terrace to provide even distribution of water flow. Automatic control of the arrangement may be provided in conjunction with temperature sensors.

IPC: G11C7/02
Filed: 1966-01-26
Abstract: 1,130,731. Semi-conductor circuits; circuits employing bi-stable magnetic elements. WESTERN ELECTRIC CO. Inc. 26 Jan., 1966 [28 Jan., 1965], No. 3436/66. Headings H3B and H3T. In a word-organized magnetic storage matrix 11, Fig. 1, in which the bit wires 18-20 are connected to respective sense amplifiers 30, each amplifier has a negative feedback circuit which includes a gate 31 normally causing low amplifier gain, the gain being increased to a high value during read-out periods by pulsing each gate. The arrangement is stated to prevent prolonged amplifier blocking caused by currents in the bit wires during write-in periods. The operation is determined by a program control circuit 10, which for a selected row wire 13, 16, 17 causes a half-write pulse from a source 29 and a full-read pulse from a source 37 to be applied in turn through a row address translator 21. Likewise the control circuit causes selected drive-sense circuits 23, 26, 27 to apply half-write pulses from sources 28 to their respective bit wires. During each read-out period the feedback circuit gates 31 are pulsed, and the high gain output of the amplifiers is applied to a utilization circuit 36 through respective discriminators 33 conditioned at the same time by a strobe pulse. A drive-sense circuit 23 is shown in Fig. 3, in which the sense amplifier 30 comprises two transistors 42, 43 energized from the associated bit wire through a transformer 40 shunted by a damping impedance 41. An inductor 58 is provided to double the output voltage swing applied from the amplifier to the discriminator 33. The amplifier feedback circuit includes the gate 31, which when pulsed on lead 32 provides a direct path to ground through a transistor 68 for alternating current in the feedback circuit. The discriminator includes a D.C. restorer 72 which comprises a transistor 76 brought into operation by desaturation when the strobe pulse is received on lead 39. The input signals are applied to a transistor 78 in a threshold circuit 74, this circuit being biased by a source 79 so that only amplified binary ONE signals received in the read-out periods can pass to a transistor monopulser 73.
