Title: Improvements in and connected with pumps for liquid fuel and other liquids
IPC: F02M59/14
Filed: 1932-12-05
Abstract: 410,537. Fuel pumps. JONES, F. J. S., Moreton, New Road, Porthcawl, Glamorgan. Dec. 5, 1932, No. 34412. [Class 102 (i).] In a diaphragm carburetter pump the diaphragm 1 is flexed against the action of a spring 25 by an oscillating lever 4. The diaphragm is held at its periphery between a flange 6 on tne body 8 and a ring 7. The centre of the diaphragm is clamped between a disc 2 at the end of the lever 4 and a disc 3. During normal working the lower edge of the disc 3 pivots on the abutting surface 31 of the body 8, but, when the diaphragm is moved to the left by the back pressure of the fuel, the disc 3 is disengaged from the surface 31 and the diaphragm executes idle movements. In a modification, the periphery of the disc 2 is bent to pivot on the external surface of the ring 7. Inlet and discharge valves 32, 35 are provided, the inlet passage 14 being covered by a strainer 23.

Patent GB-950342-A (GB)
Title: Method of preparing thin magnetic films
IPC: G11B5/64
Filed: 1961-09-27
Abstract: A thin magnetic film of Ni/Fe alloy is formed on a substrate using as electrolyte a mixture of Ni and Fe salts and a small amount of an alkali metal hypophosphite, the pH value not exceeding 3, and preferably 1.7-2.8.  A magnetic field may be applied during plating. The substrate may be of polished metal or glass pre-plated first with Cr and then with Au, e.g. by vapour deposition.  For example, a glass plate pre-coated with chromium and gold is plated in a bath containing NiSO4, FeSO4, boric acid, saccharine, laucyl sulphate, sodium chloride, and .05-.4 g. per 1. of sodium hypophosphite. Plating conditions are 4-6 V., C.D. 6 m.A. per s.cm., pH 1.5-3.4, for about 1-2 minutes.  A film of thickness 800-1600 A is formed which contains 14-23% of Fe.  The effect of varying the iron and hypophosphite content of the bath on the magnetic properties of the film are described.

Title: Improvements in electrical indicators or measuring instruments
IPC: G01R5/14
Filed: 1935-12-16
Abstract: 467,441. Current and pressure meters. GAUSS, H. E. Dec. 16, 1935, No. 34929. [Class 37] In an indicating or measuring instrument of the kind comprising a magnetic armature which is polarized to lie when tmdeflected transversely of the direction of the deflecting field, the armature is so formed that one of its surfaces acts as a mirror and reflects light from a source on to a suitable scale or screen. The instrument comprises a support 6 for the deflecting coil 15, and for a polarizing magnet 16, and the armature 10 is carried by a spindle 11 fitting in depressions in a brass sleeve 9, which is arranged within a cup-like portion of the support 6. The latter is filled with oil and a transparent cover 13 of the shape shown is arranged thereon whereby the level of oil is raised to the line 12 and air bubbles are excluded from the space above the armature 10. The latter may be made of a block of stainless steel, the upper surface being ground and polished and formed by stamping with a polished, hardened steel tool: alternatively, the armature may be of soft iron ground and polished and if necessary plated, and provided with a protective coating of lacquer. The reflecting surface may be plane or of concave spherical or cylindrical form. If concave cylindrical, a line image is formed which is particularly suitable when the instrument is used as a tuning indicator for a wireless set, in which case the screen 18 is provided with a transparent V-shaped or triangular portion, which co-operates with the line image. The line image moves parallel to the base and across the surface of the transparent portion as the current through the coil 15 is varied and tuning is effected until the line has its maximum (or minimum) length at which point the set is in line. Specification 264,176, [Class 37], is referred to.

Title: Weighing scales
IPC: G01G19/00
Filed: 1921-12-29
Abstract: 173,522. Toledo Scale Co., (Assignees of Hem, H. O.). Dec. 29, 1920, [Convention date]. Platform machines; steelyard arparatus; casings.-In a weighing scale having a beam lever in the connection between a platform mechanism and an automatic indicating mechanism, a link connecting the platform lever to the beam lever, and another link connecting the indicating mechanism to the beam lever are attached to the beam lever on the same side of and equidistant from the fulcrum so that the beam lever normally moves with the platform and Indicating mechanism without effect upon the operation of the scale, said beam lever carrying poises and being capable of receiving a counterweight to increase the capacity of the scale. As shown in Fig. 1, the dial housing contains a pendulum mechanism 4 actuated through a tension rod 7, lever 6 and flexible bands 5. The lower end of the tension rod 7 and the upper end of a tension rod 11 are coupled to the beam lever 10 at points equidistant from the fulcrum f, and the pull due to the load on the platform is transmitted to the tension rod 11 bv means of a draw rod 13 and, if desired, a lever 12. The beam lever 10 carries two tare beams 25 situated within a depression formed by two plates 64, 65. The plates are detachable to give access to the beam lever. To increase the capacity of the machine a weight 42 may be deposited on the end of the beam lever by turning a handle 52. The handle rocks a cam 50, Fig. 8, and thereby actuates the weight-moving lever 46 and at the same time moves a lever 56 so as to indicate the changed capacity of the machine at a window 57. The cam 50 is shaped so as to retain the lever 46 when in the extreme positions. If the pendulum mechanism 4 be disconnected, its absence may be compensated for by placing a weight 60 upon a pan 61. The poises 30, 31 of the tare beams each contain a slidable plug 32, Fig. 9, having a notch through which the tare beam slides. By screwing up a knob 34 the lateral pressure of the notch clamps the poise and beam together. The beam lever 10 carries a sealing weight which may be adjusted along a screw by means of bevel gearing operated by a shaft extending through one of the arms supporting the tare beams 25. The screw is pressed longitudinally by a spring to eliminate play. The sealing weight carries a vertically adjustable weight to regulate the pendulum effect of the scale levers. To facilitate correct reassembling of the cabinet 1 upon its platform (not shown) flanges 70 are attached to the cabinet and are drilled with holes in registration with corresponding holes in the platform below, and dowel pins are inserted in the holes.

Title: Process for the production of sheets, bands, threads and the like from rubber-latex, or the latices of guttapercha, balata, synthetic rubber and the like, and articles produced by this process
Filed: 1935-12-19
Abstract: Sheets, tapes, and threads are made by coating a band of paper, cardboard, fabric, or metal, surfaced with viscose or a substance which imbibes water in similar manner, or of "Cellophane" (Registered Trade Mark) or viscose, by spreading, spraying, pouring or passing it over the surface of a dispersion of natural or synthetic rubber, guttapercha, or balata, and drying and stripping the product.  The sheets may be given a marbled effect by allowing latices of different colours to flow on to the surface of a latex bath from which the band picks up the coating; or the band may be sprayed with colours before passing over the latex. The band may be printed or pressed to reduce its absorption in places.  Fibres or leather or cork powders may be dusted on to the wet sheet.  Natural or synthetic resin dispersions may be added to the dispersion, which may also contain a coagulant, vulcanizing agents, accelerators, stabilizers, fillers, colours, or waxes, and may be applied hot or cold.  Threads are made by applying the dispersions through nozzles to the moving band.  They may be twisted, plaited, or rolled together, rendered non-tacky by passage through a bath of starch, dextrin or gum arabic, with or without wax, or may be covered with thread or fibres.
