Title: Method for the making of water-soluble film-forming synthetic polymers
IPC: C08F120/06
Filed: 1955-03-25
Abstract: Water-soluble film-forming polymers are made by polymerizing a metallo-amine salt of a vinyl monomer containing a carboxyl radical, e.g. zinc ammonium acrylate.  Polymerization may be carried out in aqueous solution in the presence of potassium persulphate.  Films cast from an aqueous solution of the polymer air dry to water-insolubility.ALSO:Complex zinc ammonium acrylate is made by reacting acrylic acid with zinc oxide, filtering off excess oxide, diluting the solution of zinc acrylate with water and then treating with aqueous ammonia.

Title: Improvements relating to supplying tyre ply material to tyre building machines
Inventor: KAISER HERBERT
IPC: B29D30/30
Filed: 1956-03-21
Abstract: 848,202. Feeding webs. SHAW & CO. Ltd., F. March 18, 1957 [March 21, 1956], No. 8791/56. Class 100(1) An apparatus for supplying plies to tyre building machines from ply-let off spools mounted on a supply stand, is characterised by an eddy current coupling or variable speed motor, means for effecting a driving connection between the coupling or motor and either the ply let-off spool in operative position, or alternatively the corresponding liner take-up spool, and control means for the coupling or motor which can be adjusted to enable the ply to be drawn off at the correct tension and speed. As shown, a plurality of ply let-off spools, 1, la, and liner take-up spools 5, 5a, are connected by chains 3 so as to pass around wheels 4 into operative position where the ply is unwound for supply to a tyre building machine, not shown. The spools 1, la are driven in operative position by a sprocket 6 engaging a chain 7 passing around sprockets 8 and 9. The sprocket 9 is rotatably mounted on a shaft 10 carried by an arm pivoted about the axis of the sprocket 9, the shaft 10 being urged upwardly by a spring 13 to maintain the chain taut. The sprocket 8 is mounted on a shaft 15 driven by a belt 18 passing around pulleys 19, 20. The pulley 20 is mounted on the output shaft of a reduction gear 21 driven by a motor 22 through an eddy current coupling 23. An electromagnetic brake 24 stops the shaft driving the reduction gear when required. Current supplied to the coupling 23 is controlled by a variable transformer, not shown, adjusted so that the coupling 23 receives an excitation sufficient to overcome the inertia and frictional resistance of the ply spool. Thus, the spool 1 is driven at a peripheral speed corresponding with the linear speed at which tyre ply material is consumed by the tyre building machine. In a modification, the ply spool is driven through a chain, by a variable speed motor controlled by a rheostat and variable choke, the setting of the choke being controlled by the position of a roller engaging the periphery of the ply material on the spool 1 so as to control the speed of the motor in accordance with the spool diameter. The chain may be actuated towards the sprocket on the spool by an electromagnet or air cylinder.

Title: Improvements in or relating to the regulation of high-pressure boiler plants
Filed: 1928-03-23
Abstract: 287,575. International General Elec-. tric Co., Inc., (Assignees of Allgemeine- Elektricitõts-Ges.). March 25, 1927, [Convention date]. Feedwater, controlling.- The feedwater, fuel and air supplies of a high-pressure boiler having a small water-storage space are preliminarily regulated in accordance with the load on the boiler and are subsequently regulated in accordance with the steam temperature and pressure. The feedwater and fuel supply valves 7, 8 are controlled by electrical regulators 9 influenced by the output of an electric generator 5 driven by an engine 4 supplied with steam from the boiler 2. When a supply valve is automatically opened upon an in. crease in the load, the quantity of water or fuel flowing past a baffle 10 in the supply pipe is increased until the increased pressure in the pipe acting downwardly on a piston 12 counterbalances the increased upward pressure of an electrical regulator 9. The fulcrum of the lever pressed upwardly by a regulator 9 is moved in accordance with variations in the steam pressure or temperature by a piston device 14 connected to the boiler steam space or to a thermostat 15 in the steam pipe. The electrical regulators may be replaced by regulators operated by the engine governor, the throttle valve or a device for measuring the quantity of steam flowing to the engine.

Abstract: 899,338. Automatic couplings for railway vehicles. AMERICAN STEEL FOUNDRIES. March 16. 1959 [May 7, 1958], No. 9022/59. Class 103(5). A rotary lock lift mechanism in an automatic coupling comprises a hook 2, Fig. 1, which may be pivoted at 3 to the coupler head, a lever connector 9 pivoted at 10 to the hook and having an eye 13 for reception of an operating rod hook (not shown), a bridge 14 across lugs 6, 8, a hook engaging rib 12, and a jaw 16 provided with an anticreep lug 17. In the Fig. 1 position the tail 18 of the hook engages the bridge 14 and the hook engages the rib 12 so that the hook and lever may move together during unlocking operation. In prior art arrangements the tail 18 had excessive width and was apt to bind at y. Fig. 3, as the hook hinged relative to the lever. Such mal-functioning is prevented in the present invention by beveling the tail 18 to an angle of approximately 13 degrees and extending such beveling upwardly to a point 20, Fig. 4, on the hub 4 so that the widths 4a. 4b of the bearing surfaces are equal.

Controllers.-A switch for 3-phase current comprises six pillars, each with two spring - plungers thereon, one self pointing upwards and the other downwards. A longitudinally - moving spindle carries three vanes for connecting in pairs the plungers both aboveand below the vanes, the upper pairs providing a reverse flow of current from that of the lower pairs. Six metal rods c - - h are secured to two insulating discs a, band carry pairs of plungers which are adapted to be engaged by vanes k, m, n on an insulating disc j on a spindle i. Six plungers s are above, and six plungers t are below, the disc j, three alternate upper plungers and their corresponding lower plungers being connected to their pillars and to the output, which may be a 3-phase motor for driving the spindles of spinning-machines. The remaining three upper plungers are connected to their respective pillars, whereas of the three lower ones two are insulated from the pillars d, h, the electrical connections being such that, when the disc j is lifted so that the vanes engage the upper plungers in pairs, the current drives the motor in the forward direction, whereas when the disc j is depressed, the motor is driven in the reverse direction. The switch may be retained in the forward or normal running direction by a roller w on a spring-controlled arm y engaging under a cam x on the operating shaft q which carries the handle r, and a spring o normally holds the disc j in the middle, or off, position. The casings 3, 2 are filled, respectively, with oil and grease.

In the form shown, the stator consists of a magnetic hub 12 carrying a coil 10 located between insulating sheets 13, 14 and enclosed by a pair of yoke members 15, 17 carrying angularly displaced pole-pieces 15p, 17p respectively extending in the same direction and wider pole-pieces 28p extending in the opposite direction and supported at the other end 12a of the hub 12. A conducting disc 16 is secured on the end 12b of the hub so that the pole-pieces 15p, 17p act as shaded poles. The member 28 supporting the polepieces 28p has teeth 31, Fig. 1, which are separated from similar teeth 30 on the disc 29, and these teeth co-operate with the permanent magnet rotor 42 which has axially extending teeth 42a at its ends to permit synchronous operation. Rotor 42 may be of cobalt, tungsten or chromium steel. The motor starts as an induction motor by means of the conducting cup-rotor 41 which may have a sheath 41b of magnetic material to serve as a return path for the flux. The rotor 42, which may carry a pinion 48, is free to rotate on the shaft 45, but such motion is restricted by the slots 51, 52 in the induction rotor 41 through which the teeth 42a of the magnet rotor pass.
