Title: Improvements in the sealing of electric conductors into quartz envelopes
IPC: H01J9/32
Filed: 1936-06-05
Abstract: 476,488. Sealing electric conductors into quartz envelopes. GENERAL ELECTRIC CO., Ltd., FRANCIS, V. J., HARRIS, N. L., and RYDE, J. W. June 5, 1936, Nos. 15765 /36, 23436/36, and 9888/37. [Class 36] The manufacture, and sealing, of leading-in conductors for high pressure mercury vapour discharge lamps, comprises the following steps in the following order : (1) attaching to each end of a strip 1 of molybdenum or tungsten not more than 20Á thick a stouter lead 7 which is preferably also of tungsten or molybdenum ; (2) placing the body formed in step (1) within a quartz tube 6 separate from the final envelope, evacuating from the tube all gas chemically reactive to the metal strip, and collapsing the tube on to the strip by externally applied heat to form a gas-tight seal between the strip and quartz ; (3) fusing the quartz part of the seal to the sides of an aperture in the envelope while the envelope is evacuated or filled with a gas chemically neutral to an electrode which is either secured to or formed on the end of the inner lead-in wire. A number of sealed foil units may be produced together by placing within a quartz tube 3 a chain consisting of foil strips 1 connected by wires 2 of tungsten or molybdenum, and evacuating the tube 3 through its upper end before collapsing it on to the strips 1, the lowest strip being sealed first and the process carried upwardly. The tube 3 is not collapsed along the whole lengths of the wires 2, so that the separate units with projecting end wires 7 can be obtained by severing the tube at the points 4. Alternatively, a number of foil strips with attached end wires are arranged separately along a quartz tube, with their end wires overlapping, these overlapping parts being left clear when the tube is collapsed, and providing free end portions at which the tube is severed. The quartz part of a sealed unit is fused to the main part of the envelope either by a butt-weld to an open neck, or by placing it within a tubular extension of the envelope which is collapsed by heating. The envelope may be filled with nitrogen during the sealing. British Specifications 18255/03, [Class 39 (ii)], 396,103, 418,906, [both in Group XI], and U.S.A. Specification 1,271,245 are referred to. Reference has been directed by the Comptroller to Specification 465,475.

Title: Improvements in Automatic Mobile Radio-Telephone Networks
IPC: H04W84/02
Filed: 1968-04-04
Abstract: 1,190,865. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 4 April, 1968 [12 April, 1967], No. 16161/68. Heading H4K. In a telephone exchange which can interconnect wired subscribers to radio subscribers over any one of a plurality of radio links and in which an allotter allots from the free radio links one to be used for the next radio call, at least some of the radio subscribers have wired line circuits (through which connections cannot be made but) which store the busy/free states of the subscribers' mobile equipments. The system is generally similar to that disclosed in Specification 1,144,010, the provision of the wired line circuits, however, allows the state of a mobile subscriber's equipment to be tested without engaging one of the radio links. These line circuits are similar to ordinary wired subscriber line circuits and thus special services such as subscriber absent service, routing dead number calls to operators and class of service facilities may be provided for mobile subscribers as for ordinary subscribers. It also facilitates charging. The subscriber's circuit for a mobile subscriber in addition to the usual meter has an additional meter which responds to special metering pulses produced by the exchange during both incoming and outgoing calls of a radio subscriber to incur an additional charge for a radio call. For a call to a radio subscriber the exchange interrogates that subscriber's wired line circuit and if the relays in this circuit indicate that the subscriber is free and available and if this is the case the call then proceeds as in Specification. 1,144,010. For call in either direction the line circuit is updated when the subscriber changes the busy/free state of his radio equipment or indicates that he will be absent from his station. Other radio subscribers (of a more mobile nature) do not have a wired line circuit and calls to them are automatically routed to an operator. Calls to unused numbers are routed to a speaking machine. Reference has been directed by the Comptroller to Specification 1,010,299.
