Title: Improvements in or relating to electric "variator" resistances
IPC: H01C7/02
Filed: 1930-07-28
Abstract: A resistance wire is formed from an alloy containing one or more of the metals, iron, nickel, and cobalt.  The alloy contains from 40-50 per cent of nickel, preferably about 70 per cent, and should be formed from metals of a high degree of purity.  The wire is preferably made from a single crystal, which may be prepared by melting the alloy in a current of hydrogen and nitrogen, inserting a quartz tube of about 1 mm. diameter, and connecting to a vacuum in order to cause the molten alloy to ascend the tube.  The quartz tube is then etched away with hydrofluoric acid and the single crystal formed is drawn to the desired diameter.  Alternatively a molten alloy of nickel and iron may be gently cooled and one of the crystals formed sawn out.ALSO:A resistance wire, formed from an iron-nickel alloy containing preferably from 40 to 80 per cent or about 70 per cent of nickel is preferably made from a single crystal.

Title: A method of increasing the throughput of vibrating sieves
IPC: B07B1/36
Filed: 1968-05-14
Abstract: 1,223,876. Vibratory sieves. RHEWUM RHEINISCHE WERKZEUG-UND MASCHINENFABRIK G.m.b.H. 14 May, 1968 [6 June, 1967], No. 22726/68. Heading B2H. The throughput of a sieve in which the sieve fabric is in direct contact with vibrating means is increased by vibrating the sieve fabric in a direction transverse to its surface, interrupting the vibration of the sieve fabric for a time equal to or greater than the time taken for the particles being sieved to settle down on the fabric, and then repeating the action. Vibration may be effected by electronically controlled electro-magnetic vibrators. The vibrators may act on the screen fabric individually, in groups or in rows. The vibration may be interrupted at several points of the sieve fabric at intervals varying from one another and the intensity of vibration may vary from one part of the sieve fabric to another.

Filed: 1947-08-26
Abstract: Polymers and copolymers containing a butadiene 1-3 hydrocarbon are made by polymerizing a butadiene 1-3 alone or admixed with another polymerizable compound, in aqueous emulsion in the presence of a water-soluble fatty acid soap and a free "higher fatty acid." Specified butadiene 1-3 hydrocarbons are butadiene, dimethyl butadiene and isoprene.  Specified other polymerizable compounds are acrylonitrile, styrene, methacrylonitrile, vinyl naphthalene, and the methyl, ethyl, butyl esters of acrylic and methacrylic acids.  The term "higher fatty acid" means saturated and unsaturated fatty acids which contain at least 10 but not more than 20 carbon atoms per molecule.  Examples of these acids are myristic, palmitic, stearic, and oleic and mixtures thereof, as well as mixtures of fatty acids obtained by the hydrolysis of coconut oil.  The water-soluble soaps may be the sodium or potassium salts of the above fatty acids.  The water-soluble soap may be obtained by the partial neutralization of the free "higher fatty acid."  The free "higher fatty acid" may be obtained by partially acidifying a water-soluble soap.  The polymerizable emulsion may include polymerization catalysts such as hydrogen peroxide, benzoyl peroxide, potassium persulphate, sodium perborate and diazoaminobenzene.  The Specification as open to inspection under Sect. 91 comprises also the use of hymolal sulphates or sulphonates, aromatic sulphonic acid salts and salts of organic bases as emulsifying agents.

Abstract: 501,539. Moulding machines. WALLACE, F. R. Aug. 31, 1937, No. 23843. Convention date, May 14. [Class 83 (i)] In sand or foundry moulding-machines having a table 12 bearing a sand-filled flask and connected to pressing and shaking or jarring mechanisms each comprising concentric cylinders 11, 8 and pistons 14a, 9 the shock of the jarring mechanism is resisted by the base 3 of the machine and not by any movable part. The plunger 14a is operated by fluid pressure and reciprocates within the hollow cylinder 11 on a rod 10 of the piston 9. The table 12 is provided with annular ribs 14, 15 adapted to engage and rest on ribs 5, 6 on the base 3 and guide sleeve 7. The table is guided by a pin 22. In use, fluid pressure is admitted by a pipe 20 to grooves 17, 18 connected by a port 19 with the interior of the cylinder 11. The plunger 14a and table 12 rise until an exhaust port 21 is tuxcovered, the pressure is thereby released and the table falls. The table is thus continuously jarred. The table is raised for pressing against a head 25 by admitting fluid pressure by a pipe 16 to the cylinder 18 of the piston 9.
