IPC: G01M3/28
Filed: 1969-02-28
Abstract: 1,207,090. Detecting leaks in pipes. C.H. ROHRER. Feb.28, 1969, No.10867/69. Heading G1S. A gas main 10 may be tested for leaks by removing a section on the main, inserting a conduit 16 and plugging the ends by caps 13, 17. The conduit 16 mounts rubber bags 15, 15A which may be inflated by high pressure mains gas taken from main 10a, compressed by pump 38 and passed through an accumulator 35 and pipe 22. High-pressure gas is also supplied via pipe 24 to the space 25 between the conduit 16 and the main 10, so that any leakage from this space may be detected by known methods. Once one section is completed the bags are deflated and the apparatus moved by pushing the pipe 34 or hauling on cable (50) Fig. 3 (not shown). Normal gas supply is maintained across the section under test through the conduit 16 and holes 31, and the main sections 10, 10a may be temporarily connected together by a bridging pipe. In Fig. 4 (not shown) a fan (70) is provided to temporarily boost the pressure. In Fig.3. (not shown) a column of liquid (66) acts as a seal to the end of the main 10. After leak detection is accomplished the space 25 may be filled with a liquid sealer and placed under pressure to fill the leaks. Excess fluid may be pumped out through the pipe 24 Vacuum pressure may be applied to the space 25 instead of high-pressure mains gas and a closed circuit television camera may be placed between the rubber bags.

Title: Improvements in or relating to variable-pitch airscrews
IPC: B64C11/44
Filed: 1938-04-09
Abstract: 517,117. Screw propellers. ROTOL AIRSCREWS Ltd., and LUSTY, I. April 9, 1938, No. 10948. [Class 114] In a variable pitch propeller installation wherein a datum speed motor is employed, this motor controls means for rendering the pitch varying motor inoperative upon failure of the constant speed mechanism. A variable pitch propeller 12 utilises the pitch changing electric motor 13 driven off a battery 14 through lines 15 and either 16 or 17. A constant speed motor 32 driven at a regulated speed from the battery 14 drives generator 31 which in turn energizes a three-phase synchronizing alternating current electric motor 24. The motor 24 drives one pinion 23 of a differential, another pinion 22 of which is driven by the engine and the planet members 25 are used to drive a bevel wheel system 27, 28, 29, 30, the latter of which is used. as a switch member 19 The circuit for the motor 24 includes an on and off switch 20 and a main switch 34. When the switch 34 is on, the motor 24 is rotated and as long as the motor and engine speeds are alike, switch member 19 remains in a neutral position. When the engine speeds up or slows down, the switch 19 receives a motion and contacts with 35 or 36 whereby motor 13 increases or decreases the pitch accordingly. In the event of an electric breakdown, switch 20 opens and the motor 13 is deenergised and the propeller then runs as a fixed pitch propeller. When it is required to feather the propeller, the switch 34 is passed over to the other pair of contacts and motor 13 operates until the switch is opened again. In an alternative, instead of a rotary electric motor 24, a reciprocating ratchet type motor may be employed.

Abstract: 552,954. Gas analysis. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Sept. 4, 1941, No. 11335. [Class 1 (i)] Small quantities of impurities in the atmosphere are detected by 'their poisoning effect on a catalyst promoting an oxidation or reduction reaction, the effect being indicated by the variation of the heat of the reaction. For example the atmosphere may be impelled by a pump 1 over a porous block 4 on to which a volatile oxidizable liquid, e.g. methyl alcohol, is dropped from a funnel 6. The air-vapour mixture is passed to a platinized filament 7, and the variation in temperature of this is recorded by an electrical device 12. Any known means e.g. a Wheatstone bridge or a bimetallic strip may be used for indicating the temperature change, and it may be used to operate an audible alarm signal. A practical embodiment is described in which the air is propelled through the device by an electromagnetically actuated diaphragm and the current used for operating this also feeds a Wheatstone bridge in one limb of which the catalytic filament is situated. Provision is made for electrically heating the catalyst to regenerate it when it has become contaminated.

Title: Improvements in or relating to gas generators
IPC: B01J7/02
Filed: 1943-07-14
Abstract: A gas generator of the type wherein a liquid reacts with a solid comprises a container adapted to hold a material capable with reacting with a liquid to generate a gas, which has a hole in one end, the hole serving both for the entry of the liquid and the outlet of the gas.  The container is surrounded by a shell slightly larger than the container to permit the latter to telescope therein, the container being fitted into the shell with the hole at the top, leaving a space where the gas collects and is cooled.  The hole in the container is of such a size as to permit the entry of sufficient liquid with respect to the material to produce a reaction sufficiently <PICT:0571694/IV/1> <PICT:0571694/IV/2> violent to expel with the gas and associated liquid the residue formed by the reaction.  In the non-operative position, Fig. 2, the container is wholly within the shell and sealed therein, while in the operative position the container is extended to project beyond the shell and be immersed in the liquid as in Fig. 3.  The container 42 containing calcium hydride has a telescopic relation to the shell 26.  In the non-operative position it is sealed with end plates 28 and 30.  These are held in position by a tongue 62. By means of a key 64 turned by hand, a strip of metal is torn off and the end plates can be removed. The container is then extended as shown in Fig. 3, being prevented from coming right out by the catch 56 contacting the baffle 40 and held in position by spring member 58.  The tube 16 is screwed into opening 34 to carry away the gas generated, the container is extended from the shell and the whole device is plunged into water.  The space above the container falls with water which wets the tissue 50 over the hole 48, then soaks through, and contacts the calcium hydride. The surge of gas bursts the tissue 50 and fills the space 25.  The operator moves the container up and down within the limits 27 and 29, removing the hot water and the calcium hydroxide through holes in the baffle 40.  The gas may be used to inflate a balloon fixed on the end of the pipe 16 for the purpose of holding aloft a wireless aerial for sending out destress signals.
