Abstract: 1530687 Making electric cables NKF KABEL BV 4 March 1976 [7 March 1975] 08692/76 Heading H1A In manufacturing a cable having a layer consisting at least partly of a cross-linked silane modified polyolefin, the layer is extruded in a non cross-linked slate and is then cross-linking by exposing it to water in the presence of a catalyst, the catalyst being incorporated in the cable in a layer other than the layer(s) containing the silane modified polyolefin. The modified polyolefin may be silane modified polyethylene, the catalyst may be dibutyl tin dilaurate and the water may be in the form of a damp atmosphere; the temperature during cross-linking may be raised to shorten the procedure. The catalyst may be mixed with a substance from which one of the other layers in the cable is to be constituted or may be applied as a layer (possibly with a binder) e.g. to the conductors and cores. The catalyst is preferably in a layer adjacent the layer which contains the modified polyolefin. Additional layers, e.g. armouring may be applied before cross-linking provided they are not water-tight. The catalyst may be applied as a layer between a conductor and its insulation to provide lowered adhesion between the two.

Filed: 1952-04-08
Abstract: 727,039. Vinegar. BRITISH VINEGARS, Ltd. June 19, 1953 [April 8, 1952], No. 8987/52. Class 14 (2). In making vinegar by aeration of alcoholic liquor containing acetic acid bacteria, acetification takes place under pressure, at least during its later stages. The rate of aeration may be increased as the bacteria multiply, the pressure being correspondingly increased to keep the volume of air or oxygen passing through the liquor in a given time substantially constant or within limits to prevent or restrict frothing. An antifoaming agent, e.g. grease or a silicone, may be added to the liquor and a mechanical or electrical foam-breaker may also be used. The alcoholic liquor may be a mixture of two thirds fermented malt wort and one third vinegar from a previous acetification. In an example, a stainless steel cylinder A closed by a lower screw cap B<1> is about three-quarters filled with alcoholic liquor, acetic acid bacteria or seed vinegar from a previous acetification are fed in through a pipe I and tap C and the cylinder is then closed by an upper screw cap B<2>. Air is admitted to .the cylinder through a pressure regulating valve G and a pipe connected to the lower cap. The air is distributed by a sintered glass aerator D and leaves through a reflux condenser E connected to the upper cap, a control valve F being fitted in the outlet pipe J of the condenser: Other forms of aerator are described.

Abstract: 630,165. Electrodeposition of metal. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 2, 1947, No. 9008. Convention date, Aug. 10, 1945. [Class 41] A process of electro-depositing metal on a base member comprises passing a plating electric current through the base member and an electrolyte to render the base member cathodic for a predetermined period of time, then passing a deplating current to make the base member anodic for a lesser period of time, the deplating current being of such density and passed for a time sufficient to apply at least 10 per cent of the contents applied by the plating current, and repeating the alternate plating and' deplating current cycle until a predetermined thickness of sound metal has been deposited on the base member. In the arrangement shown, a tank 10 contains an electrolyte 14, a base member 24 to be electroplated, and an electrode 28. The base member and electrode 28 are supported by hangers from conductors 16, 18 connected to a source 20 of alternating current. The source may be a battery, directcurrent generator or rectifier combined with relays, reversing switches and resistances operated by a timing mechanism to reverse the current at predetermined times. Preferably, in each cycle of operations the base member is made the cathode for from 2 to 40 seconds, and then the current is reversed so that the base member is the anode for from ¢ to 10 seconds. Examples are given of the electrodeposition of copper, brass, zinc, cadmium silver and gold, using cyanide baths.
