Abstract: 1309449 Electrostatic pinning of films E I DU PONT DE NEMOURS & CO 11 May 1970 [12 May 1969 23 March 1970] 22677/70 Heading B5B [Also in Division H1] Apparatus for electrostatic pinning of a thermoplastic dielectric web or film to a chilling drum in manufacture (Fig. 1) comprises a hopper lip 30 from which film is extruded at 33 to contact the periphery of a moving quench drum 29; an electrode 25 transverse of the web being connected to direct high voltage source 15 and a gas supply pipe of dielectric material being provided with a transverse slot 32 to maintain a gaseous atmosphere round the wire; whereby the film is charged electro-statically to adhere to the drum. A point probe for electrostatic charging may comprise (Fig. 2, not shown) an elongated electrode surrounded by a dielectric sleeve to which gas is supplied for ejection round the electrode point. In a modification (Fig. 4) wire 25 is embraced by a concentric sector of a cylinder comprising an inner dielectric cylinder and an outer earthed electrode 41 through which a stream of gas is passed from a source 16. Adhesion force may be tested (Fig. 3, not shown) by drawing film from a roll across a polished earthed stainless steel block by a spring balance registering adhesive force; the film being electrostatically charged in a gas atmosphere by a point probe (Fig. 2, not shown) supplied from a gas source over a flowmeter with electrode voltage the maximum permissible without breakdown.  The gas is, e.g. nitrogen, helium, dry air, oxygen, dichlorotetra fluoro ethane, dichloro difluoromethane, tetrochloro ethane in nitrogen, acetone vapour in nitrogen, carbon tetrachloride in dry air or nitrogen; and is tested by passage through a transparent dielectric chamber 50 (Fig. 5) containing an insulated earthed steel plate 53 masked by dielectric film 57 leaving a central gap over which a tensioned wire electrode 58 is positioned spacedly at right angles; the spacing determined by blades 59. After purging with dry air, test gas is admitted and direct voltage is increasedly applied to the wire over a microammeter, and the average voltages for threshold current and for spark breakdown are determined; after which the microammeter current at 0À1 kv. before breakdown is determined as "wire current before breakdown". The desirable gas has the last factor at least 100 ÁA per inch of exposed wire, and margin of at least 2 kv. between threshold current voltage  and spark breakdown voltage. A melt-cast of film polyethylene terephthalate is exemplified.

Abstract: 447,007. Vehicle spring-suspensions. GENERAL MOTORS CORPORATION, Grand Boulevard, Detroit, Michigan, U.S.A. Aug. 12, 1935, No. 22681. Convention date, Aug. 17, 1934. [Class 108 (ii)] In vehicle independent wheel suspensions in which each wheel is supported by a longitudinal vertically swinging arm or lever the pivot axis of the arm is arranged obliquely to the medium vertical plane of the vehicle. As shown, for steerable wheels the wheels are carried by arms 8, 9 supported on brackets 4, 5 by pivot axes 6, 7 which are substantially horizontal but oblique to the central vertical plane of the vehicle. The brackets 4, 5 are pivoted on king pins 2, 3 carried by the chassis member 1 while the wheel axes 10, 11 are secured to the outer ends of the arms 8, 9, the arrangement being that the axes 6, 10 and 7, 11 are co-planar but intersect, if produced, on the vehicle side of the wheels. Steering arms 17, 18 are secured to the brackets 4, 5 and connected by a track rod 16. To provide the usual camber the axes 6, 7 instead of being quite horizontal are inclined slightly downwardly and the required caster effect may be obtained by means of the king pins or other usual means. It is stated that the suspension decreases the effective leverage of the centrifugal force in cornering, increases the centripetal force tending to turn the vehicle in cornering, reduces the steering effort required and increases the load on the inner wheel while reducing that on the outer wheel in cornering.

Title: Water electrolyzer
IPC: B22F3/11
Filed: 1958-07-16
Abstract: 895,352. Electrolytic cells. RUHRCHEMIE A.G., and STEINKOHLEN-ELEKTRIZITAT A.G. July 16, 1958 [Aug. 1, 1957], No. 22775/58. Drawings to Specification. Class 41. An electrolytic cell, e.g. for electrolysing water, comprises a cathode consisting wholly or in part of Raney nickel, and an anode consisting wholly or in part of Raney nickel, Raney silver, or silver. Raney nickel and Raney silver are produced by dissolving out the alloying metal (e.g. Al, Zn or Mg) from an alloy of that metal with Ni and Ag respectively. The electrodes may be made by mixing a pulverulent Raney alloy of Ni or Ag with a powder of the pure metal constituting the active constituent of the alloy, i.e. Ni or Ag, respectively, pressing, sintering and dissolving out the alloying metal, to obtain an electrode comprising a nickel or silver skeleton in which particles of Raney nickel or Raney silver are embedded, to provide a double skeleton electrode, e.g. as described in Specification 806,644. The ratio of pure metal to Raney alloy in the original mixture may be 1: 1. The anode may comprise a substrate, e.g. a steel plate, having a coating of the Raney nickel, Raney silver or silver, and the cathode may similarly comprise a Raney nickel coating on a substrate. The coating may be provided by pressing and sintering a powdered alloy layer with or without finely-divided metallic skeleton material on the substrate and dissolving out the alloying metal. When the anode is Raney silver or silver, a diaphragm resistant to silver peroxide and impermeable to silver ions, e.g. p-phenylene diamine formaldehyde resin, is employed between the electrodes. If bipolar electrodes are employed, the anode surfaces should comprise Raney nickel as the active constituent.
