Title: Improvements in or relating to electro plating
IPC: C25D3/40
Filed: 1949-03-17
Abstract: 662,660. Electrodeposition of copper. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. March 17, 1949 [May 1, 1948; Feb. 18, 1949], Nos. 7328/49 and 7329/49. Drawings to Specification. Class 41. A process of electroplating copper on a base member from an aqueous cyanide electrolyte having copper dissolved therein, comprising applying a plating electric current to the base member while in contact with the electrolyte for a period of not more than 40 seconds, then applying a deplating current of a predetermined magnitude for a period of time to deliver at least 10 per cent of the coulombs delivered during the preceding plating period to effect removal of a part of the previously plated copper, and continuing the alternating plating and deplating process until a desired thickness of copper has been deposited, is characterized in that the electrolyte contains dissolved zinc, the concentration of which is maintained between 0.004 and 0.57 ozs. per U.S.A. gallon (0.03 and 4.27 grams per litre) of the electrolyte. The duration of each deplating period is preferably not longer than 10 seconds. The zinc may be derived from an anode consisting mainly of copper but containing between 5 per cent and 0.1 per cent by weight of zinc. The electrolyte may contain as additions agent a betaine having at least one non-cyclic hydrocarbon' radical which contains from 10 to 20 carbon atoms, the betaine being present in a concentration of 0.01 to 1.0 oz. per gallon. The electrolyte may also contain thiocyanate in a concentration of 0.1 to 10 ozs. per gallon.

Title: Improvements in or relating to means for controlling the movements of automobile vehicles
IPC: F16B1/00
Filed: 1942-06-02
Abstract: 561,234. Controlling motor vehicles. A.C.E. MACHINERY, Ltd., and EVANS, P. N., June 2, 1942, No. 7470. [Class 79 (v)] The reversing gear of a vehicle is controlled by a pedal d mounted on a shaft f and normally held in the central or neutral position by a spring p, the pedal being rocked forwardly to give a forward drive to the vehicle and rearwardly to give a reverse drive. In the construction shown, the pedal is formed with toe and heel plates q, rand is connected by a link h to a sector i fixed to a shaft k having an eccentric j controlling the reversing gear (not shown). The sector is normally. held in the neutral position shown by means of a spring p connecting the ends of two arms l, m which bear against the sides of the sector and are pivoted at n, o respectively. Thus movement of the sector in either direction stretches the spring p which then tends to return the sector and the pedal to the neutral position. The reversing gear may be a friction gear as described in Specifications 561,233 and 561,235, ' [Group XXIV]. When the pedal is released and returns to its neutral position, a brake may be automatically applied to the driving gear as described in Specifications 561,236 and 561,238, [both in Group XXXIV], so that the vehi.cle.is automatically brought to a standstill. The engine c drives the rear wheels e through the reversing gear controlled by the pedal d. Front wheel brakes may be provided and controlled by a separate pedal.

Title: Improvements in or relating to rotary valves of internal combustion engines and the like
IPC: F01L7/08
Filed: 1943-05-12
Abstract: 566,180. Valves. ASPIN, F. M. May 12, 1943, No. 7571. [Class 7 (vi)] Rotary valves, such as those described in Specifications 463,412, 535,856 and 562,549, adapted to be cooled by liquid introduced into the valve are provided with a sealing washer 11 which confines the cooling liquid to the inlet tube 13, cooling space (not shown) and outlet passage 16, 17, 18 and a separate sealing washer 12 which prevents lubricant from leaking up the valve stem towards the cooling system, the washers being spaced apart to form an intermediate neutral chamber 19 from which any leakage drains away through a passage 20, 21. As shown, the washers are arranged backto-back and a conical cap 22 secured to the valve stem rotates therewith in the chamber 19 to throw off cooling liquid from its upper and lubricant from its lower surface. Leakage is reduced by introducing the cooling liquid at a pressure slightly above atmospheric and withdrawing it at slightly below that pressure. In a modification, separate chambers are provided for the collection of the cooling liquid and the lubricant.

Title: Improvements in safety razors
IPC: B26B21/50
Filed: 1924-03-27
Abstract: 230,641. Elley, M. March 27, 1024. No Patent granted (Sealing fee not paid). Razois, safety. In a safety razor in which a double-edged blade is carried by a holder mounted between the two arms of a frame carried by the handle and the guard also forms a guide for the strop when the blade is being sharpened, the onepiece member which forms the guard and strop guide is slidable with respect to the handle so as to permit the strop being readily passed under the roller with which it engages when stropping the blade. As shown the guards d form the extremities of two prong-shaped members c carried by a tubular member b slidable on the handle a and the top surfaces of the guards in the lowest position, Fig. 4, act as guides when the strop is being inserted under the roller f and automatically double the strop over the blade as the guard and guide is slid to its uppermost position on the handle, Fig. 6, for guiding the strop when sharpening the blade l. The bladeholder, journaled in the arms of the frame e consists of two semi-cylindrical parts k, the upper of which has two projections engaging perforations in the blade and abutting against the other part and a ring at one end embracing such part; at the end opposite to the ring the frame is slotted so that, when the holder is turned with the blade in line with the handle, the blade and upper half of the holder may be slid out of the frame for the purpose of removing or replacing the blade. The lower part of the holder carries a crank o engaging a slotted arm n on the roller f which is also journaled in the frame, and when sharpening the blade, the strop is pulled to and fro to rotate the roller f and thus rock the blade from side to side of the strop to sharpen both sides of its edges. The roller and blade-holder are locked in the shaving position, Fig. 2, by a screwed rod g carrying a cap h which covers the blade-holder and bends the blade on to the guard, the rod being secured in position by a member i rotatably mounted in the handle and engaging the rod. A modified blade-holder comprises a shuttle upon which the blade is positioned and which slides into a hollow slotted shaft journaled in the frame.

A profile is formed on the peripheral surface of a roll 6 by electro-erosion using a tool electrode 17 of the desired shape which during erosion is moved along a straight path whilst the roll is rotated about its axis. A pair of rolls 6, 6<SP>1</SP> which are to be used in combination for rolling turbine blades, have their peripheral surfaces eroded by a copper electrode 17 of blade profile, mounted in a chuck 16 of a work-head 14 which is fed automatically by a servomotor in dependence upon the operating conditions in the spark-gap. Both rolls 6, 6<SP>1</SP> are mounted on rotatable spindles 4, 4<SP>1</SP> which are adjustable horizontally on a base 1. Endless belts 11, 11<SP>1</SP> of plastic or preferably steel pass around pulleys attached to the rolls and around vertically adjustable tensioning rollers 8, 8<SP>1</SP>. The belts are attached to their pulleys by pins 13, 13<SP>1</SP> and are clamped by a bracket 20 to the work-head 14. Thus the rolls rotate with the same linear speed as the feed of the electrode. The apparatus is in a dielectric liquid during the erosion operation.
