Title: Improvements in or relating to a process for the continuous vulcanisation of rubber or the like
IPC: B29C48/08
Filed: 1941-09-06
Abstract: 550,895. Vulcanizing rubber. PIRELLIGENERAL CABLE WORKS, Ltd., and BARRON, H. Sept. 6, 1941, No. 11405. [Class 70] The vulcanization of long lengths of rubber or rubber-coated articles such as hosepipes, electric cables &c. or of articles connected together in chain-like formation is effected by carrying the articles continuously through a bath of molten alloy of low melting point. An alloy of lead, tin and bismuth may be used and the melting-point is varied by altering the proportions of the ingredients. An alloy having a melting-point just below the vulcanizing temperature is used. The sudden immersion in the molten alloy causes expansion and porosity which is advantageous in some cables. The porosity may be increased by incorporating in the rubber gas-generating substances such as ammonium carbonate or bicarbonate, and successive layers of such rubber mix alternated with vulcanization may be applied. To obtain a non-porous product, a covering of paper, cloth &c. is wound round the rubber, or a pressure of steam is maintained above the surface of the alloy, or the rubber enters the alloy at a place where the alloy is under hydrostatic pressure, obtained, for example, by a seal 7 in one leg of a U-tube, through which the cable &c. 4 enters the molten alloy, the other leg 1 being filled with the alloy.

Title: Improvements in and relating to the electro-deposition of zinc
IPC: C25C1/16
Filed: 1927-04-29
Abstract: 280,103. Tainton, U. C. April 29, 1927. Zinc and manganese dioxide, obtaining; electrodes.-In the electrolysis of zinc sulphate solutions, particularly those obtained from ores and containing manganese sulphate, anodes consisting mainly of lead but containing a substantial proportion of silver are employed. The zinc deposit is free from lead, and the formation of " trees " is avoided, enabling the electrodes to be arranged nearer together without danger of short-circuiting. Manganese, when present, is precipitated as dioxide at the anode in the form of a very fine powder containing so little lead that it may be used directly in dry cells, for varnish and ink manufacture and other purposes. Manganese sulphate may be added to the electrolyte in order to set free additional sulphuric acid for use in leaching the ore. The silver content of the anodes is preferably 250 ounces per ton of alloy, but may exceed one per cent. The anodes may also contain tin or one to five per cent of arsenic. The anodes may be in the form of freely perforated sheets. Two such sheets are placed about an inch apart between each pair of cathodes. The anodes and cathodes are maintained parallel to one another about # inch apart by grooved guides of wood or hard rubber fixed in the cell. An anode sheet may be made by rolling a core of arsenical lead having a layer of leadsilver on each side.

In belt gearing wherein a vertical drill spindle 14 is driven by an electric motor 16 through stepped pulleys 20, 22, the belt 24 and pulleys are surrounded by a guard wall 26 on a base-plate 34 pivoted at 30 and supporting the motor 16 so that tilting of the guard about the pivot 30 to the dotted line position slackens the belt and exposes the pulley 20 to facilitate belt-shifting. The plate 34 extends under the pulleys 22 and 20 and fits around the headstock 12 to allow the downward tilting movement. The motor 16 is supported on a bracket 32 secured by bolts 42 in slots in the plate 34 to allow the belt tension to be predetermined. The belt tension is then maintained by the weight of the motor 16, the tension being greatest when the belt is nearest the pivot 30, i.e. at low drill speeds. Clockwise tilting of the plate 34 is limited by a set-screw 45 adjustable in bracket 32 and abutting the headstock 12. The guard 26 may be held in the tilted position by a spring-loaded plunger (not shown), carried thereby and engageable with the headstock. In a modification the pivot 30 is replaced by a pivot at the end of the headstock 12 adjacent the motor 16 and a spring biases the guard to the tilted position. The guard is then retained in the horizontal working position by a spring-loaded plunger carried by the bracket 32 and engaging a stop on the headstock 12. According to the Provisional Specification the lugs engaging the pivot 30 are slotted and the belt tension is predetermined by adjustment of the plate 34 relative to the pivot.
