IPC: H04Q3/545
Abstract: 1,053,348. Automatic exchange systems. AUTOMATIC ELECTRIC LABORATORIES Inc. Dec. 17, 1964 [Dec. 17, 1963; March 17, 1964; March 18, 1964], No. 51414/64. Heading H4K. In a multi - stage cross - point switching arrangement, the controlling relays A, B, C of successive stages, each with an associated diode, are multiply connected in series between terminal units TU and junctors J. When a terminal unit is seized, either on an originating or a terminating call, wire P is marked by negative potential and the junctors are scanned to find an idle one connected to an idle throughpath, resistors being included in the outputs of the junctors. When this condition is found, the junctor output is earthed directly to operate the associated relays A, B, C which lock in series over wire C in series with busy relays TLAB, TLBC of the links and of the junctor. the operating circuit being opened. To avoid the effect of a spurious marking condition arising from noise, the application of the operating earth is delayed for about 5 ms. after scanning is complete. In the system shown in Fig. 3, a. calling line is extended over matrices A, B, C, originating junctor OJ and matrix R to a register-sender 360. The dialled digits are stored, and a translator 370 and magnetic drum 373 are employed to determine the routing. In the case of a terminating call, the group selector 330, which comprises matrices A, B, C, selects a path from a terminating junctor TJ through matrices E, D, B, A to the called line.

Abstract: 1,231,524. Filters. A.M.F. Inc. 5 Nov., 1969 [19 May, 1969], No. 54147/69. Heading B1D. In a filter comprising filtering material 59 arranged between a peripheral chamber and a central chamber in a housing 12 which has an inlet 13 for liquid-to-be-filtered and a liquidoutlet 15, the cover 23 of the housing is associated with a movable bar 25 which indicates when the filtering material is getting dirty and, in the upper part of the housing, there is a piston 43 which moves down and permits direct communication between the peripheral and central chambers when the filtering material is clogged. The bar 25 is connected to piston 43 via linkage 53, 51. The piston is actuated by spring 47 which operates when the differential-pressure overcomes the force of the spring. The piston first moves bar 25 to the warning zone of the cover 23, but as the differential-pressure builds up the piston is moved further downwards so that it reaches below the enlarged area of support 41 which permits communication between the peripheral and internal chambers of the filter. The bar 25 now enters the "by-pass" zone on cover 23. An electric alarm which may be incorporated into the system. This electric alarm switch can be correlated with the bar indicator or may operate independently. Vent valve 33 serves as an additional safety device, opening under sufficient pressure to allow gas or liquid to escape from the housing.

Headings C7B and C7F. Particles of substantially uniform shape having metal surfaces are produced by electro-chemically depositing surface metal on to substantially uniform particles which form a fluidized bed electrode in a plating bath. The particles may have a core of metal, glass or plastics material. If the core is non-conducting, it is first coated with metal by electroless deposition or by vapour deposition. Glass beads may be treated with a solution containing silver nitrate and ethanol prior to electroless deposition of copper from a bath containing cupric carbonate, sodium hydroxide, glycerol and formaldehyde. Zinc may then be electro-deposited from an electrolyte zinc sulphate and potassium hydroxide using a spiral nickel anode and a copper current feeder to the fluidized cathode. Alternately lead may be electro-deposited upon a nickel layer deposited electrolessly, using as electrolyte a solution of lead fluoroborate and gelatine and using a platinum spiral anode and a copper or nickel spiral as current connector to the fluidized cathode.

Abstract: 1328800 Quenching thyristors CABLEFORM Ltd 16 Sept 1970 [23 Sept 1969] 46726/69 Heading H3T [Also in Division H2] A series traction motor A is supplied from battery source B through a thyristor TH1 which is triggered by pulses from terminal 1 after amplification by transistors 2, 3, the frequency or mark-space ratio of the pulses being controlled by a pedal on the vehicle. The thyristor TH1 is turned-off by a commutating capacitor C1 through thyristor TH2 which is triggered by pulses amplified by transistor 5 from terminal 1 and supplied in anti-phase to those at thyristor TH1. After the thyristor TH1 has been turned-off, capacitor C1 is charged in excess of the battery voltage through thyristor TH2, due to the source of inductance, and starts to discharge through an inductance L1 and diode D2. The thyristor TH2 is continuously gated during the inter-pulse periods so that current continues to flow through the inductance L1 via the components D2, TH2. The voltage on capacitor C1 thus remains at battery voltage and energy from the source inductance is transferred to the inductance L1 and subsequently from L1 to capacitor C1 when thyristor TH1 begins and thyristor TH2 ceases to conduct. A further inductance may be connected adjacent to the battery, Fig. 2 (not shown). The thyristors may be protected against gate current while a reverse anode voltage is present by providing a diode between gate and cathode, and a diode with series resistor between gate and anode. The diodes are polarized in opposition to the thyristor. The protective diode arrangement may be applied alternatively in the amplifier controlling the thyristor.
