Title: Improvements in and relating to breech buffers for automatic firearms
IPC: F41A25/02
Filed: 1958-02-03
Abstract: 870,657. Breech buffers for automatic weapons. VERWALTUNGSGESELLSCHAFT DER WERKZEUGMASCHINENFABRIK OERLIKON. Feb. 3, 1958 [Feb. 8, 1957], No. 3452/58. Classes 92 and 119. [Also in Group XXXII] A breech buffer for an automatic firearm has a piston 6 displaceable axially in a cylinder against a liquid 1 under excess pressure which allows the recoil and advance of a breech (not shown) to be effected entirely through the compressibility of the liquid. The liquid 1 in the main reservoir communicates by way of a non-return valve 8 with a reservoir 2 in which is a compensating metal bellows 9 filled, through a valve 10, with a highly compressed gas. A silicone liquid of high compressibility may be used.

Title: Improvements in and relating to gas meters
IPC: G01F3/22
Filed: 1933-02-06
Abstract: 405,799. Gas meters. SUTHERLAND, A. G., and SUTHERLAND, Ltd., A. G., Warwick Road, Grect, Birmingham. Feb. 6, 1933, No. 3547. [Class 54.] The valves 1, 2 of a dry gas meter are moved in arcuate paths over grids 3, 4 formed with gas ports by levers engaged by a crank shaft rotated by the bellows, so that, apart from the engaging surfaces of the valves and grids and the engaging surfaces of the levers and the crankshaft, the only surfaces offering direct frictional resistance to the movement of a valve and members directly connected therewith are those of the single bearing by which the valve and lever are connected to the meter casing. Fig. 1 shows one construction in which the valves are actuated by bell-crank levers 6, 7 which are pivoted on bearing pins 13, 13a and have slotted ends 8, 9 engaging cranks 10, 11 on a shaft rotated from the flag spindles 20, 20a. In another construction the valves are secured at their narrow ends to links pivoted to the casing, and at their broad ends to slotted levers engaging the crank shaft. In a further construction shown in Fig. 5 the valves 1, 2 are hinged to levers 51, 53 which are pivoted on bearing pins 56a, 56 and are slotted at 50, 52 to engage a single crank 49 on the crank shaft. The connection between the valves 1, 2 and levers 51, 53 is rigid in the plane of normal operation of the valves. A bar 59 extending above the valves prevents the valves from jumping off the grids.

Title: A process for supplying a coating on at least a portion of a metallic surface and a metal article produced in such process
IPC: C23C4/08
Filed: 1960-02-01
Abstract: In a process for coating a metallic surface, the surface is rapidly heated in air to 1300-1800  DEG F. and a nickel-chromium alloy sprayed thereon, the coated surface being then heated to 1800-2250 DEG F. in order to interdiffuse and to alloy the coating with the substrate.  The object may subsequently be heated to 300-1400  DEG F., a coating of aluminium applied by spraying or hot-dipping, and a final heat-treatment effected at 1500-2100  DEG F.  The nickel-chromium alloy consists of Ni 70-97%, Cr 3-30%, with other constituents not exceeding 10% in all.  The process is applied to the protection of ferrous-base and nickel-base exhaust valves of internal combustion engines.

Steam is passed into the top and/or bottom of the chamber A or steam may be generated in heating pipes situated in water at the bottom of the main chamber. Steam is exhausted through outlets a1, b1 in the chambers A, B, respectively, and an auxiliary chamber E having an outlet e1 facilitates exhaust at the entry to the chamber B. Between the chambers E, B and A, B, respectively, the fabric passes through vertical or inclined slots at the sides of which are heating elements.

In a polyphase winding for the rotor of an asynchronous motor, each of the phase windings A, B, C consists of four branches forming a bridge circuit connected to inductive reactances 5 ... 10 mounted on the rotor outside the machine. Each phase has P 1  pole-pairs between the points 1, 3 and P 2  pole-pairs between points 2, 4 and, as shown, the windings and reactances are star-connected with respect to the points 2, 4.

A windscreen cleaning system includes a switch 23 for energizing an electric windscreen wiper motor 25, a switch 14 which when closed energizes both the wiper motor 25 and a windscreen washer motor 17, and a turning device 18, 19 operable when the switch 14 is opened to maintain energization of the wiper motor 25 for a predetermined period. The switch 23 when closed energizes a relay coil 22 to close contacts 26 to energize the motor 25, whereas the closure of the switch 14 energizes a relay coil 13 to close contacts 15 to energize the washer motor 17 and contacts 16 to charge a capacitor 18 to render a transistor 21 conducting to energize the relay coil 22 and the wiper motor 25.

Alternative control circuits are described by which after the opening of a switch either both wiper and washer motors continue to be energized for the same period, or the washer motor continues to be energized for a shorter period than the wiper motor.

Abstract: Solvents are continuously recovered from air or gases by moving a solid adsorbent material, e.g. activated carbon, between porous or partially porous walls through which solvent-laden air or gas is passed transversely to the moving stream of adsorbent material. Activated carbon descends by gravity through sections 3, 4, 5 of a tower; solvent is adsorbed in section 4 from air passing in through line 21, and is removed in section 5 by the passage of steam through line 23, being recovered in cooling plant 27.  The carbon is withdrawn at 32 and conveyed by means of compressed air through line 33 back to the hopper 1.  In section 3 the carbon is dried by hot air introduced at 18.  The porous walls may be formed by wire mesh shutters, louvres, or perforated material.  Two sections, <PICT:0666715/III/1> arranged either in series or parallel, may be used for the adsorption stage.
