Patent GB-419391-A (GB)
Title: Improvements in or relating to the electro-deposition of metals
IPC: C25D1/04
Filed: 1933-07-04
Abstract: 419,391. Electrodeposition of metal. WILLIAMS, A. I. WYNNE-, 12a, Raleigh House, Larkhall Estate, South Lambeth, London. July 4, 1933, Nos. 19015 and 26773. [Class 41.] Metal is deposited on a slowly rotating mandrel 1 in close proximity to which there are mounted skimming members 7 which are reciprocated circumferentially to disturb the cathode film of electrolyte, the travel being such as to permit the continuous removal of the deposit at 18 as sheet or tape. The skimming members may be perforated rectangular plates of celluloid, the perforations being more numerous at the middle in order to prevent excessive deposit at the edges. They are mounted on baffles disposed parallel to the flat surfaces of the mandrel, the baffles being reciprocated by linkwork. Glass bristles may be mounted on one or both sides of the skimmers so as to scour gently the anode and /or the cathode. In the case of a long mandrel, the skimmers may consist of wires under tension. The anode consists of metal bars 4 supported on a smooth frame 5 down which the bars may slide as they are consumed, fresh bars being added as required at one or both sides ; the frame is provided with a contact strip 6. The anode may be initially built up of bars diminishing in section to one side or the centre ; or the frame may be eccentric to the mandrel and the bars of uniform section. The cathode may be of stainless steel or may be plated thickly with chromium and ground before use. The unsubmerged part of the cathode is maintained wet by circulating electrolyte or by make-up water. When the axis of the mandrel is submerged, contact with it is made by means of a conducting rod projecting into a bore in the shaft and insulated throughout its length except at the bearing end ; good contact is maintained by spring loading or by tilting of the mandrel. In an example for the deposition of copper tape a bath containing 15 per cent of copper sulphate and 10 per cent of sulphuric acid at 120‹ F. is employed with a current density of 180 amps per sq. ft. The mandrel revolves once each hour and the skimmers make 120 oscillations per minute. Specification 8305/15, [Class 41], is referred to.

Title: Improvements in or relating to the dedorisation of benzene hexachloride
IPC: C07C17/38
Filed: 1943-11-22
Abstract: The odour associated with benzene hexachloride obtained by the addition chlorination of benzene is improved by treatment with aqueous nitric acid of at least nitrating strength. Advantageously, a suspension of the benzene hexachloride in aqueous nitric acid of constant boiling composition is boiled until the hexachloride, which at first fuses, has re-solidified. The crude benzene hexachloride treated may be such as is obtained by treating benzene with chlorine in the presence of actinic radiation to give a solution or slurry of the hexachloride in benzene and flushing off the benzene with hot water (see Specifications 586,439 and 586,442).  In an example, the crude, coarsely ground benzene hexachloride is added to 0.7 to 2 times its weight of nitric acid of specified gravity 1.4 and the suspension is boiled for 2 hours.  The product may be used in pest-control compositions, e.g. in those described in Specification 573,689.

Abstract: 677,039. Preventing inductive disturbance. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Aug. 10, 1950 [Aug. 13, 1949], No. 19919/50. Class 40(iv). [Also in Group XXXV] A loading coil for telephony purposes comprises two side circuit windings 13, 15, the inductances of which are capable of being equalized by making one or both of the windings movable along the central rod 1 of a ferro-magnetic core. Movement of the winding 13 along the rod 1 allows more of the magnetic flux to link with the turns of the winding, thus increasing its inductance. Coarse adjustment of the inductances may be made by axial movement of the rod, the inductances varying in opposite senses, whilst a finer adjustment is obtainable if part of the winding 15 is arranged around the winding 15 and vice-versa. If the windings are wound bifilarly, as is the case if they are constructed to function as phantom coils, the wires are twisted through 180 degrees at each transition to a succeeding layer.
