Title: Improvements in electro-capillary transducers
IPC: H04R1/42
Filed: 1946-01-18
Abstract: 602,150. Telephone instruments. STOREY, O. W. Jan. 18, 1946, No. 1808. Convention date, Jan. 22, 1945. [Class 40 (iv)] A transducer comprises a capillary electrometer 4 connected to a Bourdon tube 7. The electric circuit is connected to supporting collars 24 and 25 on which are mounted electrodes 15 and 9 which pass into the electrometer and make contact with mercury therein. One or more slugs of an electrolyte such as dilute sulphuric acid are provided in the capillary portion 4 between portions of mercury. The movement of the meniscus under charging electric potential causes a pressure change in the mercury which causes the Bourdon tube to flex and operate the loud-speaker cone 27. The apparatus is reversible and can act as a microphone. The Bourdon tube is made of glass and a space 14 contains gas under pressure which keeps the Bourdon tube completely full.

IPC: B23P6/04
Filed: 1920-01-20
Abstract: 155,471. Kelly, T. D. Jan. 20,1920. Metallic and rust cements.-In a process of repairing, re-lining, re-covering, joining, or filling up holes or cracks in metal articles, powder or filings of the same metal as the article or of a mixture of the metals is made into a paste with a saturated solution of chlorine and then applied to the part or parts and left to harden under atmospheric influence. To make. the paste adhesive until the chlorine acts on the metal, a small quantity of water-glass cement is added. The article may be formed with irregular holes, wavy lines or shallow grooves for the paste to adhere to. In filling up holes, these are first made irregular, and if the hole penetrates right through the article, a reinforcement of the same metal or a close netting may be embedded in the paste. A suitable paste is made up of 1 lb. of the metal powder or filings, mixed with 2 or 3 fluid ounces of a saturated solution of chlorine and half to one ounce of water-glass cement.

Abstract: 709,147. Gas turbine plant. LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT. Jan. 28, 1952 [Jan. 29, 1951], No. 2325/52. Class 110(3) A gas turbine plant adapted to utilize a natural source of gas which may be incombustible gas or a mixture of incombustible gas with a combustible gas comprises a compressor which supplies only sufficient air for complete combustion of the fuel to a combustion chamber feeding the turbine, a supply duct which supplies natural gas to the combustion chamber to cool the combustion gases and control means responsive to the temperature at the outlet of the combustion chamber to control the supply of natural gas. Air from the compressor 12 is heated by the exhaust gases from the turbine 10 in a heat exchanger 21 before passing to a combustion chamber 11. Only sufficient air for the combustion of the fuel supplied through the conduit 22 is supplied by the compressor 12. The temperature of the gases supplied to the turbine 10 is reduced by mixing natural incombustible gas from a source 25 with the gases. The amount of gas supplied is controlled by a valve 34 operated by a temperature sensitive element 33 to maintain the inlet temperature to the turbine constant If the pressure at the source 25 is considerably higher than that in the combustion chamber 11. the natural gas may be throttled or expanded in a turbine or other prime mover 27 before being supplied to the combustion chamber. If a turbine or other prime mover is used the natural gas may be preheated before use in the turbine 27 in an exhaust gas heat exchanger 32. A modification in which the natural gas is mixed with the combustion gases in a chamber integral with but separate from the combustion chamber is described. The natural gas may be a mixture of CH 4  and CO 2  in the ratio of 35-65 per cent by volume.

Abstract: 607,057. Gear-cutting. BROWN & SONS (HUDDERSFIELD), Ltd., D., and FEARNS, S. Jan. 24, 1946,-No. 2350. [Class 83 (iii)] In a machine for hobbing helical gears, the hob 11 and the worm 31 driving the rotary work-table 27 through a worm-wheel 30 and gears 29, 38 are both rotated by an electric motor 26, the worm 31 being driven through change gearing 37 and a universally-jointed shaft 34; a cradle 52 pivotal about the axis of the work-table carries the worm 31, wormwheel 30 and gear 29 and has teeth meshing with a worm 53 driven from a shaft 45 that also drives a shaft 51 providing the feed motion for the hob saddle. The shaft 45 is driven, through change gearing 44, from a separate motor 40 or, alternatively, from the motor 26. Any alteration in the speed of the hob is accompanied by a corresponding variation in the speed of the work-table which, combined with the hob saddle feed and influenced by the creep given to the worm 31, gives the desired helix angle to the teeth of the work-piece. The rate of hob saddle feed can be altered while work is in progress and is accompanied by a corresponding change in the rate of creep.

Abstract: 982,848. Radiographic film holders. GENERAL MAGNAPLATE CORPORATION. Jan. 23, 1962 [Jan. 24, 1961], No. 2411/62. Heading H5R. A film holder comprises a pair of flexible sheets overlying each other (between which the film is interposed), and connected together so as to allow relative movement only longitudinally, at least one of the sheets being a unitary structure including both a layer of a flexible crease-resistant opaque material and also an intensifying screen. The form shown comprises a pair of thin sheet-like members 12, 14 of flexible crease-resistant material. The longitudinal edges 26, 28 of both sheets are bent into a Z-shape, the two Z-shaped edges engaging as shown. Thus the two sheets can slide longitudinally with respect to each other, while the space between them is maintained light-tight. In this space is disposed the film 16. Each sheet member has a surface layer of material 18 acting as an intensifying screen, and a light-opaque layer 20 which may be aluminium foil, with an intermediate layer 22 of a crease-resistant plastics material. Between each of the adjacent layers 18, 22 and 20 is a thin lamination of a soft pliable material 24 such as polyethylene, which facilitates the bonding together of the layers. The total thickness of the holder, including the film, is less than 1/32 inch. A continuous length of the holder may be spooled into a roll (Fig. 6, not shown) and lengths cut off as required. The end of a severed length of the holder may be closed in a light-tight manner either by a suitable closure cap, or by sharply folding over the end. Fig. 7 (not shown) illustrates the holder wrapped round a cylinder or pipe under radiographic inspection. The edge of the holder may be marked with indicia, which will subsequently appear on the film, so that the position of any flaws in the pipe which show up on the film may be located more readily.
