Title: Improvements in and relating to electric incandescent lamps and methods of manufacturing the same
IPC: H01K3/20
Filed: 1966-08-25
Abstract: 1,140,119. Glass to glass or metal seals. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 25 Aug., 1966 [28 Aug., 1965], No. 38116/66. Heading C1M. [Also in Divisions C5 and H1] In making an electric incandescent lamp, the flanged end of an exhaust tube is shaped round the leading-in wires by heating and compressing the tube into an annular recess on a surface enclosing the wires, while the exhaust tube is kept open by inserting a mandrel, a filament is mounted between the wires, the lamp neck is placed over the tube, heated and pressed on to the tube while a stream of cleaning gas is blown through the needle, withdrawing the needle and pinching the foot to seal the exhaust tube. The leading-in wires 5, 6, Fig. 1, are supported in holes 4 in a recess in a table 1, a hollow needle 8 being also passed through a central hole in the table and a heated exhaust tube 3 is pressed into the recess. The needle is coated with a lubricant consisting of zirconium and magnesium oxide to prevent sticking. Support wires may also be sealed into the end of the exhaust tube if desired. The mount so formed is disposed on a plate and a bulb 15, Fig 7, slipped over the end, a hollow needle 16 being inserted in the exhaust tube and an inert gas, e.g. argon or nitrogen, is blown through this to expel the air while the bulb 15 is heated and sealed to the tube. Two forming pieces 19 are then arranged round the softened neck of the bulb and inert compressed gas is blown in through the needle to assist in shaping the bulb. For vacuum lamps, the bulb is then exhausted through the exhaust tube 3 and sealed off. For gas filled lamps, either the lamp is exhausted and filled with inert gas or a hollow needle of diameter smaller than the tube 3 is inserted and a flushing gas serving also as a filling gas is blown into the bulb displacing the air or other gas in the bulb. The bulb is finally provided with the usual metal cap. For lamps having a base of compressed glass without a metal cap, the pinching jaws for sealing and shaping the base have upper portions for shaping the bulb. For lamps in which the filament extends at right angles to the leading-in wires, thereby necessitating the use of a bulb with a wide neck, a dish like part to which the bulb neck is sealed, is provided on the exhaust tube.

Filed: 1945-02-16
Abstract: 592,804. Multiplex pulse signalling; valve circuits. ANDERSON, E. W., and McDERMOTT, T. J. Feb. 16, 1945, No. 4028. [Class 40 (v)] [Also in Group XXXVIII] A circuit responsive only to a predetermined group of pulses, comprises a delay circuit, to the input'connections of which the pulses are applied and which produces a coincidence of pulses at the input and output connections to which means are made responsive for producing an output signal. As described the pulse group serves as the synchronzing signal in a pulse multiplex system and consists of three 0.2 to 0.3 microsecond pulses separated by 3 microsecond intervals. The signal may alternatively be used in a television system. Incoming pulses are lengthened by the multivibrator circuit V1, V2 and squared in the cathodefollower stage V3 before being applied through resistance R2 to a line network LN, having a delay time equal to the intervals between the pulses. The surge impedance of the network is effectively open-circuited, being connected to the suppressor grid of a biassed-back pentode V4.. The control grid of V4 is connected to the input of the network. The valve V4 passes current only when a pulse exceeding 1.5 times the input amplitude is applied to the control grid at the same time as a pulse is present on the suppressor grid. When the three pulses to which the circuit is selective are applied to the network, the first passes through the network, is reflected from the output end and reaches the input again to coincide with the third and produce a double amplitude pulse on the control grid of V4. Simultaneously the second pulse reaches and is reflected from the open output end of the network to produce a double amplitude pulse on the suppressor grid. The resulting negative pulse at the anode of V4 is taken from terminal 0 for synchronization or other purposes. Specification 590,215 is referred to.

Title: Method of preparing methylchlorosilanes and methylhydrochlorosilanes
IPC: C07F7/16
Filed: 1966-09-09
Abstract: Methylchlorosilanes and methylhydrochlorosilanes, especially CH3SiHCl2, (CH3)2SiHCl, (CH3)2SiCl2, and CH3SiCl3, are prepared by reacting MeCl with hydrogen in the presence of Si, Cu and metals, or salts of metals, of Group VIII, at temperatures between 300 DEG  and 400 DEG  C.  The contact mass may be prepared by adding aqueous salts of Group VIII metals to a silicon-copper alloy or to a mixture of silicon and copper powders, or the dried salts may be mechanically mixed with Si/Cu.  ZnCl2 is a further preferred additive.  The metal salts are preferably the chlorides, nitrates, oxalates or formates of Fe, Co and Ni in amounts between 0.3 and 10% by weight of the mass. In the case of the chlorides and nitrates, the mass is first treated with H2 at 360-400 DEG  C. before being used in the synthesis.  An alternative preparation of the contact mass involves precipitating oxides of copper and the Group VIII metal, mixing the oxides with silicon powder and reducing the oxides with H2 at 340-360 DEG  C. The contact mass can be continually re-used with periodic introduction of fresh mass.

Abstract: 1,154,043. Photo-electric motion translator. MARCONI CO. Ltd. Sept. 12, 1966 [Sept. 10, 1965], No.40618/66. Heading G1A. [Also in Division H1] An arrangement for developing an electrical output which is representative of the angular position of a shaft, comprises means actuated by the shaft for varying the relative position or orientation of a source of electromagnetic radiation with respect to a photo-sensitive semi-conductor device of a first conductivity type disposed symmetrically about an axis of rotation and having one or more regions of a second conductivity type, which may be planar and mounted in a plane normal to the axis of the shaft, or cylindrical about the shaft. The arrangement may replace selsyns in self-synchronous or repeater systems. The semi-conductor if cylindrical as in Fig. 2 may operate as a lateral photo-voltaic device and may have symmetrically arranged non-rectifying line contacts 1, 2, 3 on or beneath its surface, the arrangement being designed to give a substantial linear relationship between the voltage across successive contacts and the displacement relative to the source 4, the source being within or without the cylinder. The cylinder may comprise a "p" type body with an "n" type overlying layer or vice versa. An alternative arrangement using symmetrically disposed p-n junctions around the periphery of a common n type body is described with reference to Fig. 8 (not shown) and the planar arrangement is described with reference to Fig. 10 (not shown). A mathematical analysis of a lateral photo-voltaic device is included, and wave forms of the devices are shown. The effect of contact thickness is discussed, and the use of magnetic radiation modulated at frequencies up to T<SP>-1</SP> where T is the minority carrier lifetime in the semi-conductor concerned, is suggested to improve amplifying arrangements. The employment of two translators in a selfsynchronous system is described with reference to Fig. 5 (not shown) and a gallium-arsenide p-n junction modulated up to 1000 MHz is suggested as a source; the emission being incoherent, or coherent and directed to illuminate a narrow band or line of the semi-conductor body. A silicon junction structure in which the lifetime T has been intentionally reduced to a value of approximately 10<SP>-9</SP> seconds may be used with such an arrangement.
