Patent GB-1258396-A (GB)
IPC: F16K17/19
Filed: 1968-02-26
Abstract: 1,258,396. Valves. W. S. MARTIN. 23 May, 1969 [26 Feb., 1968], No. 9120/68. Heading F2V. Pressure and vacuum relief valve e.g. for petroleum storage tanks on ship or shore, comprises a first flap member mounted for pivotal movement in a tubular housing, urged to a rest position in which it closes the housing and adapted to pivot away from the rest position in response to pressure from one side, and a second flap member pivotable about the same axis as the first member, urged to a position in which it closes an aperture in the first member and pivotable away from the closed position in response to pressure from the other side. As shown, a first circular flap 22 is pivoted about an offset axis 24 so that it is biased by gravity to closed position against a semi-circular seat 26. A second circular flap 28 within an aperture in the first one, is pivoted on the same axis 24 which is offset in the opposite direction from the diameter E of this second flap. The second flap is weighted to closed position by a plate segment 30 which overlaps the aperture to stop the flap 28 in closed position. Excess pressure beneath the valve is relieved by opening of the first flap and vacuum beneath the valve by opening of the second flap. In another embodiment, Figs. 3-5 (not shown), a rectangular frame 40 for mounting in a vertical conduit is partitioned to form two parallel flow ducts (45, 46) providing respective valve seats at opposite ends respectively of the frame. A pair of first flaps (52, 54) engaging the seats are fixed to two F-shaped arms (49) pivoted on a shaft (48). A second pair of flaps (60, 62) which close apertures in the first flaps, are fixed to similar arms (57) pivoted on the same shaft (48). The arrangement is such that the first flaps open to relieve excess pressure and the second pair to relieve vacuum. The device is gravity loaded to closed position, or springs may be used instead.

Abstract: 1,258,597. Respiratory apparatus. COMMISSARIAT A L'ENERGIE ATOMIQUE. 30 June, 1969 [11 July, 1968], No. 32840/69. Heading A5T. An exhalation device for a respiratory mask comprises a canister having a valve seat 18 against which is biassed a resilient valve member 20, a spring 38 exerting an additional force on the valve member, and a releasing mechanism consisting of a cord 36 secured at one end to a cup 40 supporting the spring and at the other end to a member movable on the canister. In a first position of the movable member, the cord is slack (Fig. 7, not shown) and the mask is suitable for use with a high pressure gas supply, and in a second position the cord exerts a pulling force on the cup 40 to prevent the spring acting on the valve member, so that the mask is suitable (Fig. 1) for use at atmospheric pressure with the user inhaling through a filter cartridge (not shown). The movable member may be a control ring 48 mounted on the outside of the cover (Fig. 1-3), a member slidable on the outside of the top face of the cover (Figs. 4-7, not shown) or a pivotable lever (Fig. 9, not shown). The device includes protective grids 30, 32.

Abstract: 1,258,777. Automatic firearms. MAUSERWERKE A.G. 9 May, 1969 [10 May, 1968], No. 23811/69. Addition to 1,142,380. Heading F3C. An automatic firearm comprises a reciprocating breech block 12 having a pair of spring loaded cartridge feed pawls 14, 15 adjusted to be moved alternately from an outward, operative position to an inward inoperative position. The positions of the cartridge feed pawls in their feeding movement are controlled by a slide member 19 which is actuated by an ammunition selector slide (Fig. 3, not shown) displaceable longitudinally of the firearm. In the construction shown the two ammunition feed ducts are positioned one above the other on the same side of the firearm and the cartridge feed devices of the ducts are gas actuated selectively, that is movement of the selector slide opens one valve member 27 or 28 while closing another valve member 28 or 27 through gearing (Fig. 3, not shown) both valve members being in communication with the bore of the barrel 11. The cartridge feed devices each comprise feed slides 17c, 18c, feed pawls and detent pawls (Fig. 2, not shown) and are each actuated by a pin 21b, 22b of a gas piston 21, 22 working in a slot 25a, 26a of an operating sleeve 25, 26, the pins 21b, 22b being constrained to move longitudinally of the firearm only. The slide member 19 carries a pin 19d which works in an angled slot in the selector slide, which slide is guided on a pair of pins of the firearm casing 10.

Abstract: 1289920 Electron-beam welding apparatus KRAUSS-MAFFEI AG 19 April 1971 [28 Feb 1970] 22580/71 Heading H1D An electron-beam welding chamber is constructed so that the alignment of the electron gun with the work is not disturbed by distortion of the chamber when it is evacuated. In the arrangement shown in Fig. 1 this result is achieved by the symmetry of the construction. The chamber comprises four steel plates 2-5 coated with lead to absorb X-rays. The upper plate carries the electron gun 14 above a central opening, the side plates have apertures 15 and 16 for a lead glass window 17 and for connection to a vacuum pump, and the bottom plate is supported by girders from a foundation 25 and carries rails on which the work carriage 9 is supported and guided; end covers are hinged to to the upper plate (Fig. 2, not shown). The wall thickness may be 40 mm. compared with the 120 mm. required in known arrangements. In a modification, Figs. 3 and 4 (not shown), the electron gun and the rails for the work carriage are mounted on a framework of girders which also carries the lead shielding; a thin-walled vacuum chamber is sealed to the electron gun and the rail support through bellows and may distort within the limits of its strength without disturbing the alignment, since this is determined by the framework.
