Title: Machine for winding stators of dynamo electric machines
IPC: H02K15/085
Filed: 1947-10-01
Abstract: 633,915. Coil-making apparatus. GENERAL MOTORS CORPORATION. Oct. 1, 1947, No. 26437. Convention date, Oct. 5, 1946. [Class 35] In a machine for winding stators, the stator is mounted in a turret oscillated between limits corresponding to the slot pitch of the coil being wound, the limits being determined by stops operated in timed relation with the shuttle laying the wires. The stator (not shown) is supported by three adjustable rollers in a turret T angularly oscillated by rack 175 on a bar 176 which is reciprocated by fluid-pressure between stops corresponding in position to the spacing of the slots being wound and the wire is laid along the slots by a shuttle 90 carried on rollers 27 and reciprocated by a roller 25 in a cam slot 24 on the drum 23. This drum also carries at one end a cam 280 operating a switch 281 (not shown) controlling the fluid supply for oscillating the turret while cams 279 at the other end operate a switch 287 (not shown) controlling the movement of fingers arranged at each end of the stator for guiding the wire. The movement of the fingers is thereby interlinked with the shuttle drive (and that with the rocking motion) so that the wire is held away from the winding zone until the shuttle is about to move and the fingers move outwards again near the end of the movement of the shuttle. A pair of stops to limit the angular movement of the turret is provided for each pitch that a coil need be wound, and a valve controlling a pair of fluid cylinders is provided for each pair of stops, the valves in turn being controlled by switches operated in turn by a cam disc on a countershaft gear driven from shaft 19. The speed of the countershaft is such that after the appropriate number of turns has been placed in one slot pair, a switch operates to change the effective pair of stops and enable two slots of different pitch to be wound. Specification 552,027 is referred to.

Abstract: 1,187,092. Feeding webs. LUMMUS CO. 8 June, 1967 [27 June, 1966], No. 26541/67. Heading B8R. [Also in Division H4] In a system for determining the amount and direction of sideways displacement of a continuous web, moving in a lengthwise direction, from a reference position, the web intercepts part of a sound wave beam and the attenuation of the beam is measured. In the Fig. 1 embodiment, the web edges move in gaps between transmitting transducers 11, 12 and receiving transducers 13, 14 defining two sound wave beams. Fixed-frequency (e.g. 30 kc./s. or higher) pulsed or continuous wave sound is used. The receiving transducer outputs are A.C. amplified at 22, 32, rectified at 23, 33, D.C. amplified at 24, 34 and compared in voltage comparator 26 whose output feeds meter 36. The relative attenuation of the two beams is dependent on the sideways displacement of the web, and the amplification is adjusted to give a " centre-zero " reading on meter 36 when the web edges are in a desired reference position. The comparator output may also be recorded or control a servosystem for maintaining the web in the desired reference position.

Title: Process for the separation of uranium and zirconium
Filed: 1959-08-07
Abstract: Uranium is recovered from a mixture or alloy of uranium and zirconium by contacting the mixture or alloy with at least an equal amount by weight of molten aluminium for an extended period and separating the zirconium-containing precipitate from the uranium-aluminium melt. The uranium-zirconium alloy or mixture is preferably first formed into pieces having at least one dimension not exceeding 12,5 mm and then contacted with 1-10 times its weight of molten aluminium at a temperature of 660-1000 DEG C. in an inert atmosphere or under a flux.  After completion of the reaction the reactants are held at 670-760 DEG C. for a period and the zirconium precipitate then removed from the uranium-aluminium melt by filtering.  Alternatively, the precipitate may be separated from the remainder of the melt by sedimentation or centrifuging and the whole allowed to solidify.  The zirconium-rich portion is then cut off the casting.  The zirconium-containing precipitate may be further treated with molten aluminium to remove adherent uranium-aluminium alloy.

Title: Improvements in or relating to the cathodic corrosion protection of metal bodies
Inventor: RISBERG EILIF
IPC: C23F13/02
Filed: 1965-06-29
Abstract: In cathodically protecting against corrosion a metal body in contact with an electrolyte solution, an anode is disposed in the electrolyte and the anode is subjected to a forced cyclic movement in a predetermined cyclic path in relation to the surface of the body to be protected.  The anode may be of the type on which no external voltage is impressed, e.g. of Mg, or of the type on which a voltage is impressed.  The path of movement of the anode may be adapted to the geometry of the system.  The speed of the anode and the current may be varied.  Periodic regulation of current may be by varying mechanical screening of the anode as described in Specification 1,117,525. Directioning of current may be obtained by varying the anode's orientation, e.g. where the anode is a plate having an insulating coating on its edges and one side. More than one anode may be used, e.g. there may be a combination of moving and stationary anodes.  A control system for the cathodic protection may comprise fixed and moving reference electrodes.  An example simulates protection of a steel cargo tank from corrosion by sea water using a magnesium anode which is forced to move in a circle.
