Patent GB-492324-A (GB)
Abstract: 492,324. Cables ; joints. STANDARD TELEPHONES & CABLES, Ltd., and WEBB, J. K. March 19, 1937, No. 8205. [Classes 36 and 38 (i)] A liquid-resisting barrier in an impregnated cable is formed by dissolving out a substantial part of the impregnant by means of a solvent, removing the solvent and dissolved impregnant, introducing a polymerizable material and then polymerizing said material. The solvent may be benzene. The process of forming a plug or termination described in Specification 460,031 may be employed, a solvent being, however, first introduced by means of the tappings or openings in the sheath and then being boiled off prior to introduction of the monomeric styrene. For making joints, the joint may be built up of paper impregnated, e.g. with resin oil, chlorinated diphenyl, chlorinated naphthalene or methyl abietate, a sleeve fitted over the joint, nipples inserted in the sleeve and in the cable sheath on either side of the joint, solvent being then introduced and removed and monomeric styrene introduced and polymerized. The process of forming a termination described in Specification 449,868 may be modified by feeding solvent into the cable end prior to the introduction of polymerizable material. In the case of belted cables solvent may be passed through the insulation until it runs clear, heat and vacuum applied, and solvent again passed through, a barrier being then formed in the core insulation and worming spaces : solvent is then applied to remove impregnant from the belt insulation and the barrier completed. The solvent may be applied under pressure, a partial vacuum being applied to the outlet nipple or nipples, and for removal of the solvent a heating coil or coils may be provided or a current may be passed through the cable sheath or joint sleeve. The sheath may be swaged or the cable may be cooled at the or each side of the barrier. Specification 429,611 also is referred to.

Abstract: 1,161,259. Plastics pipes. RAYCHEM CORP. 31 Oct., 1967 [31 Oct., 1966], No. 49492/67. Heading F2P. [Also in Division C3] Heat-recoverable pipes having elastic memory properties are prepared by subjecting pipes made of polymeric materials to a dosage of radiation sufficient to cross-link the polymeric material in one surface portion of the pipe to an extent which renders it infusible, but insufficient to render an opposite surface portion of the pipe infusible. Specified polymers are polyolefins, polyvinyl halides, polyvinylidene halides, ethylene/vinyl acetate and ethylene/ethyl acrylate copolymers, and polyamides. Elastic memory properties may be imparted by deforming, e.g. expanding, the tube at elevated temperature and cooling in the deformed state. Examples describe the differential irradiation of (1-3) polyethylene and (4-6) plasticized polyvinyl chloride tubing.

Patent GB-503437-A (GB)
Abstract: 503,437. Voltmeters. EVENDEN, E. F., and P. & B. ENGINEERING CO., Ltd. Nov. 18,1937, No. 31748. [Class 37] A thermal-type voltmeter for indicating maximum and minimum voltages on an A.C. circuit has a main pointer adapted to actuate maximum or minimum pointers, or both, the scale being open at the region of the nominal voltage and movements of the pointers above or below the nominal voltage being restricted to cover the small remaining part of the scale above and below the permissible voltage limits A pointer a is operated by a pair of coaxially mounted bimetallic coils b, b<SP>1</SP> of which the rear coil b is heated by one or more elements c coupled to the supply line through a step-down potential transformer d loused in the base e. The other coil b <SP>1</SP> carries the pointer a and serves to compensate for temperature changes. The primary winding of the transformer d is connected to terminals f mounted on an insulating block g and projecting beyond the base flange for connection at the back of the panel. A central hole in the block g allows access to an adjusting screw h for varying the distance between the heater c and coil b. The secondary winding of the transformer d may have an output of about 5 amps. at 1 volt with a primary voltage of the nominal value and is connected to 'the heater c through leads i, terminals i<SP>1</SP>, and metal strips c<SP>1</SP>. The heating element c has considerable thermal capacity in order to produce a definite time lag, for example of ten minutes, so that variations in supply voltage of short duration are neglected. The time lag may be increased by enclosing the heating element in refractory insulating material such as asbestos composition. The pointer a co-operates with a scale j which has open and approximately uniform divisions covering the permissible limits of voltage variation. Friction-controlled pointers l, m are actuated by movement of the pointer a so as to indicate maximum and minimum readings. The pointers l, m are formed with hubs engaged by friction discs controlled by adjustable springs, and are reset by pins s actuated by knobs t and engaging tail-pieces q, r on the pointers. The open scale through a limited range may be obtained by so arranging the heater c and coil b that a sufficiently open scale is produced over the whole range and then restricting the actual motion of the pointer by stops to the required limited range. Alternatively the magnetic circuit of the transformer d may be so arranged that the output is magnified in relation to the normal transformation-ratio over the desired range or, according to the Provisional Specification, a choke-capacity or like coupling may be employed to produce resonance effects. The Provisional Specification also states that a hot-wire or moving iron voltmeter may be employed. Specifications 370,543 and 483,422 are referred to.

The generator is run as a motor from the battery 68 to start the engine on closure of a switch 80. Under normal conditions the generator charges the battery and supplies loads 70, 72 through a series field winding 64 and cut-out 82. The relav 96 with its coil connected across the generator and series field 64 is sensitive to current demands on the generator and holds the ignition circuit closed only as long as the generator is supplying current either to charge the battery or supply the loads 70, 72. Specification 504,180 is referred to.

The invention relates to a rocket engine in which a hollow toroidal cavity is formed around the nozzle throat and one or both of the propellent fluids is injected into the cavity whereby the nozzle throat is cooled, the propellent fluid or fluids being discharged from the cavity to flow along the wall of the combustion chamber in a direction opposite to the flow of combustion gases from the chamber, thus acting as a cooling film. In Fig. 1 the rocket engine comprises a combustion chamber 9 having a propulsion nozzle 8. The nozzle is formed with a throat 10 and a toroidal cavity 7 is formed around the throat. Propellent components are supplied through lines 2 into the cavity 7 and flow along the wall thereof as indicated by the broken lines, the components discharging from the cavity 7 to flow along the wall of the combustion chamber as a coolant film. The combustion gases produced in the chamber finally discharge through the nozzle 8. In Fig. 2, one propellent component may be injected through inlet 13 to the cavity around the throat of nozzle, while a second component is injected through an inlet 14 to flow along the wall of the combustion chamber. Again, one component may be injected through inlet 16 into the cavity around the nozzle throat while the second component may be injected through inlet 15 adjacent the component discharging from the cavity. The rocket units may be of substantially spherical form as shown or they may be of annular form formed by rotating a section such as shown in Fig. 1 or Fig. 2 about an axis displaced from but parallel to the axes of the units shown.
