Title: Improvements in apparatus for detecting minute potential differences in alternating current systems
IPC: G01R19/00
Filed: 1939-06-27
Abstract: 531,538. Valve voltmeters. WARREN, T. R. June 27, 1939, No. 13475/40. Divided out of 531,477. [Class 37] Means for detecting minute potential differences in A.C. systems comprises a transformer S across the primary winding S1 of which the E.M.F. to be detected is applied through an inductance T. The winding S1 is tuned by a condenser U to resonate at the supply frequency. The secondary winding S2 is connected to the grid of a triode L through a resistance V. The sensitivity is varied by means of a potentiometer X, across which is a condenser Y which is conjunction with the resistance V reduces the harmonic content of the E.M.F. between the terminal H1 and earth. Between the anode and cathode of the valve L is the primary winding P1 of a transformer P, a condenser Q being connected in parallel with this winding so as to form a resonant circuit at the supply frequency. The secondary winding P2 is connected to a milliammeter R. An inductance M and condenser N in parallel are inserted between the anode and the positive D.C. supply in order to eliminate harmonics between the anode and cathode.

IPC: C10J1/12
Filed: 1919-05-29
Abstract: 148,027. Campbell, D. E. May 29, 1919. Spray carburettors.-Apparatus for making gas suitable for lighting, heating, or power purposes comprises means for subjecting a hydrocarbon oil in the form of a high-velocity jet to violent concussion against an anvil surface, and means for simultaneously mixing the gas produced with air. The oil, contained in a reservoir 20, is supplied by a pump 2 driven from a gas-engine to a pipe 16 leading to a discharge nozzle 12, Fig 3. controlled by a needle valve 23 and contained in a mixing-chamber 11. A rotary air compressor 3, driven from the gas-engine, supplies air to the mixing-chamber 11 through a pipe 36. The oil is discharged violently against an anvil 46 which is carried by the foremost of a series of coneshaped screens 45 behind which is a series of baffle plates 47. The gas produced passes through a check valve 53, and is delivered by a pipe 52, Fig. 1, partly to a gasometer 55 and partly to the gas-engine driving the pump 2 and compressor 3. The particles of oil that escape gasification drain into a trap 48 together with any oil which collects in the mixing chamber 11, and are returned by a pipe 71 to an auxiliary fuel tank 72. The tank 72 is provided with a float valve 73. and is connected to the delivery pipe leading from the main fuel reservoir 20. The production of gas is intermittent and is regulated by the position of the gasometer, acting through a weighted rod 61. The rod 61 is provided with collars 62, 63 which, through an arm 67, actuate a trip lever 31 connected by links 30 and 44 respectively to the fuel needle valve 23 and to a by-pass valve 41 in the air supply. To allow the pump 2 baffle-plates 47. The gas produced passes through a check valve 53, and is delivered by a pipe 52, and compressor 3 to continue working when the valves 23 and 41 are closed, a by-pass connexion 18 provided with a diaphragm valve 19 is fitted on the fuel supply pipe 16, and a pipe 42 is provided which connects the air-inlet pipe 5 with the delivery pipe 36 leading from the compressor.

Abstract: 950,601. Erasing magnetic records. AGFA A. G. April 19, 1960 [April 18, 1959], No. 13698/60. Heading G5R. To prevent noise being inserted on a magnetic record by the uni-directional action of the Earth's magnetic field at the point in space where the alternating erasing field is decaying towards zero, the erasing means is enclosed in a ferrite or magnetic screening alloy housing spaced sufficiently from the erase means to prevent magnetic saturation by it. In Fig. 2 a normal erase core 1, carrying windings 2, is enclosed by a screen 5, a portion 6 of which is hinged to allow a tape 4 to be threaded there through and erased free of the effect of an undesired field Hst. In Fig. 5, a winding 2 causes oscillatory discharge of a capacitor C to bulk-erase a reel of tape 4 inside a screening box which denies access to the Earth's field H E . The use of a test tape, as described in Specification 939,689 [Group XXXVI] is referred to.

[Class 104 (ii)] [See also Groups VII and XIII] In a shoe factory a conveyer having a plurality of tracks is arranged along a production line at spaced points in the length of which successive manufacturing operations are performed. Preferably, the conveyer comprises superposed pairs of angle-iron rails 40, each pair supporting and guiding trays 42 of rectangular section engaging the rails by large-diameter balls 44. From 3 to 6 tracks may be provided, the topmost trays being under 5 feet from the floor. For the first part of the manufacture the trays may have cross-members in the spaces between which the shoes may be supported bottom uppermost. These crossmembers may be inclined so that the work may face the side of the conveyer at which the majority of the machines are located. After the soles have been secured the conveyer may comprise one less track than up to that point. From this point trays may be returned along the bottom pair of rails. The remainder of the conveyer may be of U or other shape in plan, and the trays used from this point may be flat, the U-shape of the conveyer returning the trays to near their starting point. At appropriate points the conveyer, or some of the runs thereof may pass through a dryer.

Abstract: 475,415. Colour photography. KLEIN, A.B. May 15, 1936, No. 13844. [Class 97 (i)] Relates to beam splitting blocks of the kind including two partially reflecting surfaces oppositely angularly disposed to an incident beam of light so that part of the beam passes through undeviated and parts are reflected laterally in opposite directions. A colour filter is provided within the block behind each of the semi-reflecting surfaces so that any stray light reflected from a portion of the prism lying beyond the reflecting plane responsible for the formation of a lateral image, will, when finally emerging from the face of the prism .adjacent to the plane in which the said image is to be recorded, be minus light which the recording filter is capable of transmitting or, if a photographic emulsion is used which does not require such a filter, which the emulsion is capable of recording. As shown, the block is built up from right-angle isosceles prisms 1, 2, 3, 4. The surfaces 17 and 20 are coated with a partially reflecting surface of, for example, aluminium. Magenta (minus green) filters 21, 22 are interposed and the prismscemented in pairs with hard Canada Balsam and dried off. The hypotenuse faces 18, 19 and 10, 13 are polished and the surface 17, 18 aluminized and cemented to the surface 10, 13 with soft Canada Balsam with the interposition of a yellow (minus blue) filter, and dried off. The filters are dyed films of, for example, cellulose acetate. This may be applied in the form of a liquid containing the dye. Of the light entering the prism, only red rays are passed through undeviated. Blue and red will be reflected through blue filter 30 to form the blue component image. Alternatively, a blue-sensitive emulsion may be used without a filter. Green and red rays are reflected through the green filter 31 to give the green component image. Alternatively, a yellow (minus blue) filter may be used with a green-sensitive emulsion. The red filter 34 is optional. A single objective 25 or separate objectives 26, 27, 28 may be used. By choosing different filters for inclusion in the block, the planes in which the three colour component images are recorded may be interchanged.
