Title: Improvements relating to electrical windings
IPC: H04M1/02
Filed: 1924-07-25
Abstract: 244,807. Ferranti, S. Z. de. July 25, 1924. Transformers.-The windings of transformers for wireless apparatus are made of an enamelled wire alloy such as silicon-bronze having a high elastic limit. This obviates the wire stretching, while being wound under tension, to such a degree that parts thereof become bared of insulation, and allows of the use of a finer wire with consequent reduction of the self capacity of the coil and of the eddy current losses. A failure would show during winding by breakage of the wire instead of stretching and consequent insulation failure. A non-magnetic iron alloy containing iron, nickel, chromium, tungsten, and carbon in the approximate proportions of 60.5, 25.99, 11.6, 1.6, and 0.36 may be used for the wire.

Filed: 1970-04-15
Abstract: 1278725 Can making machinery; special work GULF & WESTERN INDUSTRIAL PRODUCTS CO 15 April 1970 [17 April 1969] 18014/70 Headings B3A, B3B and B3T A method of trimming a can body or the like comprises making a circumferential cut in the body, thereby forming a burr extending outwardly from a surface of the body, and removing the burr. The trimming apparatus comprises a main drive-shaft 36, which is driven by an electric motor 12, and on which are mounted head turret assembly C and tail turret assembly D. As the shaft 36 is rotated a can J is deposited in a cull assembly G. A rod 98 is driven towards the assembly C by a cam 86 thereby feeding the can on to a head turret spindle assembly E where it is held by fingers 91, rod (338) and tail spindle (D), Fig. 2 (not shown). The spindle assembly is rotated by the motor 12 via a belt and pulley drive 28, 44, 48 and a shaft 50, which carries a pinion 52 meshing with a ring gear 54. Gears 60 on the spindles are driven by the ring gear and thus rotate independently of the head turret. Trimming assemblies H are mounted on shafts 606, on which are secured arms 609 engaging in a cam track of a fixed cam member 610. As the head turret rotates, the cam arms 609 pivot the assemblies H so that their cutting knives M progressively cut through the ends of the can bodies J, Figs. 6-6F (not shown). The burr formed during cutting is removed by a spring-loaded roller mounted on each assenbly H. The burr may alternatively be removed by a non-rotating shoe, an abrading wheel or shoe or by a secondary knife. The can bodies make a plurality of revolutions during cutting and trimming of the burr. As the assembly C continues to rotate, the trimming assemblies H are pivoted clear of the can body which is discharged from the apparatus in known manner. Each knife M is mounted on a member (632), Fig. 4 (not shown), and is formed with a point 740 and a cutting edge 742, which engage the can body J to one side of a vertical line through the rotational central axis of the head turret spindle assembly E. The cutting edge is angled rearwardly so that the reaction force P acts outwardly, thereby pulling the burr due to cutting to the outside surface of the can body.

Abstract: 313,505. Holzverkohlungs-Industrie Akt.-Ges., and Varga, J. June 12, 1928, [Convention date]. Grant of Patent refused. Hydrogenation, destructive.-Carbonaceous materials are treated with hydrogen or with gases containing or yielding hydrogen at high temperature and pressure in the presence of hydrogen sulphide or materials yielding hydrogen sulphide and molybdenum or tungsten or both or their compounds. The amount of hydrogen sulphide may vary between 1 per cent and 6 per cent by weight of the initial material, and the optimum concentration varies for different materials. Suitable sources of hydrogen sulphide are free sulphur, alkali and alkaline 'earth sulphides, and organic sulphides such as thiophene and carbon disulphide. The sulphur content of the starting material is taken into consideration in determining the amount of hydrogen sulphide to be used. Activators such as boric acid and chromium compounds may be added. The products of the hydrogenation are almost entirely saturated aliphatic, aromatic, and hydro-aromatic hydrocarbons free from compounds of oxygen, sulphur, and nitrogen, and are stated to be sufficiently pure for use as motor fuels, lubricants, &c., without further treatment. Numerous examples are given. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of from 6 to 12 per cent of hydrogen sulphide. This subject-matter does not appear in the Specification as accepted.
