Title: Improvements in or relating to submarine communication conductors
IPC: H01B7/14
Filed: 1929-04-22
Abstract: 332,573. Western Electric Co., Ltd., (Bell Telephone Laboratories, Inc.). April 22, 1929. Drawings to Specification. Cores for cables. - The core of a submarine cable consists of a number of insulated strands so arranged that each strand passes at frequent and regular intervals from the interior to the! surface of the core and back. Such an arrange.- ment can be produced by stranding three wires together, stranding the resultant wires in threes, and continuing until a twenty-seven or eightyone strand conductor is produced. The conrluctor is then compacted by rolling, swaging or drawing. The strands may be insulated by impregnating with Chatterton's compound, bitumen, or melted rubber, or they may be covered with powdered talc or alundum in glycerol, which may be afterwards boiled off. Alternatively the surface of the wire may be oxidized or plated with a metal such as chromium which is then oxidized. A filling and insulating material may also act as a pressure equalizing substance as described in Specification 184,782. The cable may be magnetically loaded. Copper prepared as may also act as a pressure-equalizing substance described in Specification 340,497, [Group II], may be employed for the conductors. Specification 322,811 also is referred to.

Title: A process for use in the production of a semi-conductor device
IPC: H01L21/22
Filed: 1962-04-03
Abstract: In making a semi-conductor device, semi-conductor material which will crystallize in a space-centred cubic lattice is deposited from the gaseous phase on a heated dislocation free mono-crystal of the same semi-conductor or one of similar lattice structure preferably prepared by crucible free zone melting as described in Specification 926,497.  Deposition by this method of germanium, aluminium, arsenide, aluminium phosphide and gallium phosphide or germanium and of gallium arsenide on aluminium arsenide or vice versa is suggested. Typically a PNPN device is formed by depositing 2 ohm. cm P-type silicon on both faces of a 20 ohm. cm. N-type silicon crystal from a reaction mixture of hydrogen and silicochloroform or silicon tetrachloride mixed with boron trichloride as dopant source.  N-type layers are then formed over the P-type material from a similar reaction mixture containing phosphorus trichloride as dopant source. Best results are achieved if the semi-conductor is deposited on a 100 crystal face, the surface of which is removed immediately before deposition by adjustment of the reaction chamber atmosphere. Specifications 692,250, 853,729, 861,135 and 914,042 also are referred to.

Title: Improvements relating to telephone systems employing selectors
IPC: H04Q3/00
Filed: 1931-05-01
Abstract: 363,273. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, London.-(Siemens & Halske Akt.-Ges. ; Siemensstadt, Berlin.) May 1, 1931, No. 12910. [Class 40 (iv).] In a system employing selectors with common control equipment temporarily associated with a selector over a hunting switch, the same test relay (P) serves for controlling the association of the control equipment with an idle selector and for the hunting operation of the selector itself. The invention is described with reference to a selector of the type having long- and short-step driving magnets. When the control equipment is associated with a selector, relay P is operated and the line switch VW tests for battery over wiper h2 and relay V2 (i). Relay V2 operates and relay I repeats impulses transmitted over the a-wire to the longstep magnet Dg in series with winding (ii) of relay V2. At the first impulse relay C2 operates over wiper h1 and releases relay P. At the end of the digit, the relapse of V2 connects relay P over wiper h4 to the selector test-wiper and completes a circuit over interrupter RV for short-step magnet Dk. When an idle outlet is found relay P operates, short-circuiting C2 and thereby permitting selectorswitching-relay C1 to operate. Relay P is now released and connected to wiper h5 to test for a free selector, the driving magnet Dh of switch h1 .. h7 being operated over interrupter RV. The operation of P when an idle selector is reached completes a circuit over wiper h7 and off-normal contacts w2 for short-step magnet Dk which restores the seized selector to normal. If a selector find no free outlet in the selected group, ground over shaft springs closed at the end of the group operates relay I over wiper h2 to disconnect P from wiper h4, so that the selector advances, without further testing, to the end of its bank at which P operates to battery over wiper h3.

Title: Improvements in or relating to hydraulic dampers
IPC: F16F9/10
Filed: 1957-04-24
Abstract: 836,045. Hydraulic shock absorbers. BRUNET, M.A. April 24, 1957 [April 25, 1956], No. 13003/57. Class 108(3) A hydraulic damper comprises a chamber 1 containing a member 31 and a liquid which is circulated by pressure caused by relative movement between the member 31 and the chamber anc wherein the liquic at a temperature of 25‹C. has a viscosity higher than 30 poises and advantageously between 100 and 100( poises. The liquid which may be a silicone e.g. methyl silicone, circulates from one side to the other of the member 31 through a constricted passage-way comprising the clearance between the parts 31 and 1, thus close tolerances are unnecessary. Alternatively, nylon spacer members may be fitted into grooves in the member 31 which may, if its diameter is only just less than the internal diameter of the chamber 1, be longitudinally grooved to form the liquid passageways. A shaft 6 carrying the member 31 is slidingly fitted in an end cap 3 of bronze, nylon or aluminium alloy having a synthetic rubber seal 4 held in place by a cap 5. A part 3<SP>1</SP> rigid with the cap 3 forms an additional braking action when it coacts with the cupped portion of the member 31, and, so that excessive pressure is not made on the seal 4, an internal recess 32 is provided to communicate through apertures 33 with the chamber 1. A rubber gum washer 8 contains substances which slowly dissolve in the liquid to compensate for any reduction in viscosity. A thermal compensating device, Fig. 8, may be incorporated and comprises an additional passageway between a head 27 and a resilient split ring 26. When there is an increase in temperature, expansion of the mass of an annular rubber block causes a compression of the ring 26 which lessens the gap between it and the head 27.

Abstract: 1,157,589. Hydrocyclones. CELLECO AB. 19 March, 1968 [30 March, ,1967], No. 13119/ 68. Heading B2P. [Also in Division F1] The discharge of a central column 6 of gas released from a liquid suspension of solid particles in the vortex chamber 2 of a hydrocyclone is effected .by suction by means of a rotary vacuum .pump 11 via discharge con duits 7, 7a and via a liquid centrifugal pump 8 which communicates at its suction side with the conduit 7a, the vacuum, pump 11 being connected to a suction line 12 which opens out as at 13 into the centre of the centrifugal pump impeller 14. In operation, a portion of fine solids and liquid is entrained with the gas and on entering the pump 8 is caught by the impeller blades 16 and pumped out through a line 10 and a collecting conduit 5a through which the bulk of the fine solids is discharged with liquid. The gas which is concentrated at the centre of the pump impeller around the opening .13 of the line 12 is sucked away by the vacuum pump 11. Vapour released from any hot liquid entering the pump 8 is simillarly removed. Thus the vacuum pump 11 serves to maintain the pumping action of the centrifuged pumps under vacuum while simultaneously the latter acts as a separator preventing liquid and solid particles from entering the vacuum pump. A number of hydrocyolones may be connected in parallel between the conduits 5a and 7a.
