Abstract: 1299352 Pressurised fire extinguishers GRAVINER (COLNBROOK) Ltd 22 Jan 1970 [5 Feb 1969] 6112/69 Heading A5A A pressurised fluid container 10, e.g. a fire extinguisher, has its discharge outlet 12 normally sealed by frangible diaphragm 13, and includes member 15 which normally supports 13 against the container pressure, rotary operating ring 22 coupled to 15, and two alternative means for applying a rotating force to ring 22 to release 15 from its diaphragm-supporting position. Diaphragm support 15 is pivotally mounted on operating head 11 by pivot pin 16 and retained by pawl 17 pivotally mounted on 11  by pivot pin 18. Seal 14 is provided between head 11 and screwed insert portion 13a of diaphragm 13. To release the container contents pawl 17 is pivoted away from support 15, allowing rupture of 13 by the container pressure and discharge of the contents through outlet 12. Spring 19 returns support 15 to its original position when discharge is completed. Pawl 17 is pivoted away from support 15 by rotation of ring 22; this is formed with slot 22a in which head 17a of the pawl fits, the longitudinal axis of 22a being eccentric to the axis of rotation of 22 so that rotation of 22 causes pawl 17 to pivot. The two alternative methods of causing rotation of ring 22 illustrated are:- (i) by tensioning flexible cable 23 which terminates in trunnion 24 engaging in further slot 22b in ring 22, the tension applied being sufficient to overcome the action of coil spring 25 and rotate ring 22, and (ii) by propulsion of piston 26 in contact with ring 22, by means of explosive cartridge 27 ignited by closure of an electric circuit, the combustion products passine through opening 28a in protective washer 28 propelling piston 26 against ring 22 to rotate the latter.

Title: Improvements in or relating to pressure control systems for aircraft pressure cabinsor the like
Inventor: TREGANOWEN BERNARD ERIC
IPC: B64D13/02
Filed: 1953-03-07
Abstract: 756,933. Fluid-pressure servomotor-control systems. NORMALAIR, Ltd. May 31, 1954 [March 7, 1953], No. 6385/53. Class 135. An outlet valve for a pressurized aircraft cabin is lightly biased to open position and is actuated in the closing direction by air at a pressure which exceeds that in the cabin and is controlled by a pressure control unit, e.g. as described in Specifications 563,553, 714,859 or 717,990. The arrangement is stated to reduce sensitivity to changes in air flow and to avoid pressure surges due to sluggish action. As shown in Fig. 1, the control unit j is similar to that in Specification 717,990 and its output pressure is connected by a conduit e with a chamber b bounded on one side by a flexible diaphragm f. A chamber d bounded by a smaller diaphragm h has a connection k with the cabin interior, and a space c between the diaphragms is connected to atmosphere. Bellows n, o secured to the diaphragms form a tubular chamber which is connected to the interior of a bellows y which carries the cabin outlet valve 3. The bellows n, o also enclose valves p, q which are actuated by a member g secured to the centre of both diaphragms f, h. When open, the valve p exhausts the bellows y to atmosphere and the valve q connects the bellows to a source of elevated pressure such as the cabin air supply pipe v. The connection is by way of a pipe t incorporating a check valve and an inwards relief valve 9a. Alternatively, the source of elevated pressure may be a Pitot head or a separate pressure vessel. Air is also passed from the pipe v through a restriction 6 and check valve 7 to a chamber 8 containing a relief valve set to limit the pressure in the chamber to 10 inches of water above cabin pressure, and an inwards relief valve 9. A bleed 10 connects the chamber 8 with the control unit j. Should the supply of air at elevated pressure cease, the check valves close so that control may be effected for a time by trapped air at elevated pressure. Subsequently cabin air passes through the inwards relief valves 9, 9a to effect control. In a modification, two cabin outlet valves 2, 2a, Fig. 3, in series are used, the valve 2 corresponding to that in Fig. 1 and the valve 2a being an emergency valve operable should the valve 2 fail. The valve 2a is controlled by valves 13, 14 actuated respectively by an absolute-pressure capsule pack 16 and a differential-pressure capsule pack 17. Specification 602,311 also is referred to.

Filed: 1930-02-26
Abstract: 339,891. British Thomson-Houston Co., Ltd., (Assignees of Kearsley, W. K.) Feb. 27, 1929, [Convention date]. Drawings to Specification. R÷ntgen-ray tubes.-Alloys of copper and aluminium, preferably containing 0.25 to 2 per cent of aluminium, are used instead of copper as the backing of anticathodes. The decrease in the space current, and so in the ray output, occurring with copper backings during the course of an exposure, possibly due to the poisoning of the cathode by gases evolved from the anticathode, is thus prevented or a rising current may be produced. An alloy containing 1 per cent of aluminium gives substantially steady current for 2 minutes. The backing has a tungsten inset cast or peened therein and is made slightly larger than corresponding copper backings to allow for its decreased heat and electrical conductivity.
