Title: Improvements in Cables for Electrical Machines adapted to be Coiled and Uncoiled.
IPC: H01B7/08
Filed: 1919-05-07
Abstract: 127,812. Electro-Agricultur Aktiebolaget, (Assignees of Grafstrom, E. A.). June 7, 1918, [Convention date]. Cables.-Electric cables which, in use, are required to be wound upon drums or wheels, have the cores interconnected so as to form a flexible ladder-like band. As shown in Fig. 2, the insulated conductors 1 are connected by rigid crossmembers 3, and, as shown in Fig. 4, by continuous material 4 such as impregnated linen cloth sewn together along longitudinal seams 5. The two forms may be combined to form a more solid construction. In another construction, the crossmembers carry uninsulated conductors on both sides, whereby the part wound upon the drum is short-circuited.

Title: Improvements in or relating to frequency measuring or indicating apparatus for an electric supply system
IPC: G01R23/02
Filed: 1931-04-17
Abstract: 375,011. Induction relays. SHOTTER, G. F., 14, The Ridgeway, Friern Barnet, Middlesex, and ELLIOTT BROS. (LONDON), Ltd., Century Works, Lewisham, London. April 17, 1931, No. 11434. [Class 38 (v).] Induction relays for controlling the frequency of a supply comprise a pair of elements each constituted of a disc or drum of conducting material rotated between the poles of an electromagnet connected to the supply, and a second electromagnet having its poles embracing the disc and connected to the supply through an inductance and capacitance forming a resonant circuit with a frequency above or below that of the supply, the discs or drums being so shaped or mounted that a differential torque is produced the resultant of which effects control of the supply frequency. In one arrangement, Fig. 1, two cam disc rotors 1, 2 rotate in the fields produced by an electromagnet 6 connected to the supply 10, the centre limb being located between the discs. Electromagnets 11, 14 acting on the discs 1, 2 respectively, are connected to the supply through inductances and condensers 12, 13 and 15, 16, the circuits of these electromagnets being tuned to frequencies above and below that of the supply. As the disc rotor moves in one direction or the other, one of the discs moves out of and the other into the fields of magnets 11, 14, thus increasing or decreasing their torques on the discs. One disc may be cam-shaped and the other circular, or a single disc eccentrically mounted with respect to the electromagnets 6, 11, 14 may be employed. In another arrangement, the discs are shaped as shown in Fig. 4, two sets of electromagnets 6, 11, 14 being employed, and the magnets comprising each pair 11, 14 may be connected to separate inductances and capacitances. Resistances may be employed in the circuits of electromagnets 11, 14.

IPC: H01M6/18
Filed: 1957-04-08
Abstract: 875,629. Batteries. EVER READY CO. (GREAT BRITAIN) Ltd. March 31, 1958 [April 8, 1957], No. 11434/57. Class 53. A cell comprises electrodes which may be of carbon and zinc, magnesium or aluminium, in contact with a solid electrolyte consisting of an ion exchange material, for example a crosslinked sulphonated polystyrene resin. The electrodes may be in the form of separate plates, and a layer of manganese dioxide may be in contact with the carbon. Alternatively, the various layers may be deposited on one another in coherent form. The carbon may be deposited by dispersing it in a solution of a thermosetting resin with which a zinc sheet is coated. The solvent is removed and the resin hardened by baking. The manganese dioxide and ion exchange layers are deposited in the same way, the latter being deposited on the manganese dioxide layer or on the uncoated side of the zinc. Fig. 3 shows four layers 18, 19, 20, 21 consisting respectively of zinc, carbon, manganese dioxide and an ion exchange resin, and Fig. 5 shows a battery comprising three superimposed cells each consisting of four layers as shown in Fig. 3. The current is led off through zinc plates 22, 26 at the ends of the battery. Specification 875,630 is referred to.

Title: Improved method and apparatus for automatically fixing the end of the thread or yarn of a wound package to the package support
IPC: B65H65/00
Filed: 1961-03-29
Abstract: 941,389. Reels. K. J. SCHARER, [trading as MASCHINENFABRIK SCHARER]. March 29, 1961 [March 31, 1960], No. 11455/61. Heading B8M. [Also in Division D1] A device for fixing the thread end of a wound package A, Fig. 2, comprises a socket 3 into which the end 1a of the bobbin extends, the socket forming part of a head 4 carrying a lever 7 pivoted at 11. The head is initially rotated by frictional engagement with the bobbin and the centripetal action on arm 7a of lever 7 causes a tapering finger 8 of the arm 7b to bear against the end 1a. When the package A has been completed, the thread is moved into the path of rotation of the finger 8 with the result that an auxiliary winding B is formed in a plane inclined to the axis of the bobbin. At this stage the package is held against rotation, but inertia causes the head 4 and the C- shaped lever 7 to continue rotation for a while, this relative rotation causing the end of finger 8 under winding B to move it into a vertical plane so that it becomes loose about the bobbin. The moving finger 8 causes some of the end turns to move under the now loose auxiliary winding and, since the thread leading up to the bobbin is now under a tension greater than that of the auxiliary winding, this tension causes the winding B to tighten on to the turns thereunder and so secure the thread.

Patent GB-858671-A (GB)
Title: Fluorocarbon acid and derivatives
IPC: C07C59/315
Filed: 1957-04-18
Abstract: The invention comprises perfluoro-oxydipropionic acid O(CF2CF2COOH)2 and its acid halides, metal and ammonium salts and alkyl esters.  The acid may be prepared by electrolytically fluorinating an oxydipropionyl halide with liquid hydrogen fluoride in a nickel anode cell to give perfluoro-oxydipropionyl fluoride and hydrolysing this to the acid.  In an example perfluoro-oxydipropionyl fluoride is obtained electrolytically from oxydipropionyl fluoride, the acid is obtained by adding a slurry of calcium oxide and acidifying the resulting calcium salt with sulphuric acid.  An alternative work-up involves the isolation of a sodium salt which is acidified as before. The silver salt is prepared using silver oxide and the carboxylate groups are then replaced by iodine to give a compound O(CF2CF2I)2. The mercury salt is prepared using mercuric oxide, the ethyl ester is prepared using ethanol and the methyl ester is prepared from the sodium salt using methyl-p-toluene sulphonate.  Mono decarboxylation to give omega-hydroperfluoro-ethoxypropionic acid by heating the acid with piperidine is also described.  A method for the preparation of the acid chloride, bromide and iodide is also mentioned. Specifications 686,678 and 735,730 are referred to.
