Abstract: 1,135,099. Electro-plating using an ultrasonically agitated bath. LITTON INDUSTRIES Inc. July 21, 1966 [July 21, 1965], No.32933/66. Heading C7B. A deposit of metal (e.g. Au) is electro-plated from an aqueous solution of at least one soluble salt of the metal (e.g. an alkali gold double cyanide) and with an ultrasonic field applied to the solution, the concentration of the metal salt, or salts, in the presence of the field exceeding the saturation concentration level of the solution with no applied ultrasonic field. The solution temperature may be elevated above room temperature and may be increased to boiling. Current densities up to 1,000 amps/sq.ft. may be used. Bright Au plate in excess of 0À01 inches may be obtained. Fig. 1 shows anultrasonic transducer 12 which agitates a plating solution 18 by first exciting another liquid 183, e.g. water. The ultrasonic frequency may be 20 kc/sec. and the intensity be 2À5 to 10 watts/sq.in. The cathode 20 may be moved slightly during plating by an agitator 26. The plating solution may contain 5 to 9 troy ounces of Au as KAu (CN) 2  per U. S. gallon. It may be at 150 F. and have a pH between 8À0 and 14À0. Possible additives to the solution are KCN or NaCN, K 2 CO 3 , potassium sodium tartrate and a wetting agent such as pentadecafluoro-octanoic acid or sodium lauryl sulphonate. Examples of electro-forming Au are: - A) Electro-plating Au on to Cu or Al then physically withdrawing the Cu or Al. B) Depositing Cu over plaster, electroplating Au on to the Cu, dissolving out the plaster with water and the Cu with acid. C) Electroplating Au on to a basis metal then machining off the Au where it is not desired. Cu, Ni or Ag and other conventional strike coatings may be used as a basis metal for the Au, e.g. zincated Al may be covered with a Cu strike before the Au is electro-plated.

Abstract: 762,680. Accelerometers; recording apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 28, 1955 [Nov. 30, 1953], No. 33267/53. Classes 106 (3) and 106 (4). An accelerometer comprises a cylindrical mass 11, Fig. 1, suspended on two diaphragms 12, 13 in inner and outer casings 14, 15 respectively, the mass 11 being secured to a cross beam 16 in turn secured to a cross bar 18 whose ends project beyond shoulders 19 of the casing 15 to prevent movement of the mass 11 to the left of Fig. 1. A cover 21, secured to the casing 15 by a ring 20, contains a locking member 22 having two limbs 23 which in the locking position press the bar 18 against the shoulder 19 and a part which, in that position, bears against a trigger 25 to stop the clockwork mechanism.. For use the ring 20 is slackened and the cover 21 and member 22 rotated until the limbs 23 clear the bar 18 and the part releases the clockwork trigger 25. Air damping is provided by forming a chamber between the diaphragm 12 and a partition 41 to which air is admitted by a bore 43. During steady movement the air pressure is equalized by apertures 44, grooves 46 and apertures 47 in the mass 11. A recording stylus 38, e.g. of phosphor bronze, with a chisel-shaped cutting edge is bifurcated to clear the bar 18 and secured in a cylindrical member 39 rotatable in a groove in the beam 16. To set the stylus pressure the required load is applied at 38a rotating the cylinder 39 which can then be locked in a position by the bar 18 on tightening the screws 17. The stylus records on a disc 37 mounted in or secured to a ring 36 removably held by a cruciform spring on a disc 32. The recording surface is formed by a film of gold of 100 Angstrom units thickness sputtered on a glass plate and subsequently heattreated for 15 minutes at a temperature up to 400‹ C. In the'embodiment shown in Fig. 1 the disc 32 is mounted on the last shaft 31 of a clockwork mechanism which only operates in response to accelerations in the required direction over a certain minimum. This control is effected by a weighted lever 53, Fig. 6, on which the trigger 25 is formed, subjected to the action of a hair leaf-spring 54 and carrying a tooth 57 adapted to lock the escape wheel 58 of the clock mechanism, the locking tooth 57 only being withdrawn when the acceleration is large enough to pivot the lever 53 against the action of the spring 54. Alternatively the disc may be immovable so that only the maximum accelerations may be recorded, or may be movable by a spring controlled by a weighted lever escapement to record separately accelerations over a predetermined minimum value but not against a time-base.

Abstract: 902,712. Winding wires. SYNCRO MACHINE CO. Sept. 29, 1960 [May 31, 1960], No. 33520/60. Class 120 (2). A winding device for taking up the untreated or unusable end of a wire to be wound on a spool 12 comprises an auxiliary spool 13 mounted on the same power driven mandrel as the spool 12, and a reciprocating traversing mechanism 22 having an arm 24 that can project over the spool 13, the wire being initially guided through the traversing mechanism 22 and over a pin 25 carried by the arm 24 so that the wire, whilst the traversing mechanism is stationary, can be wound on the auxiliary spool 13. When sufficient wire has been wound on the spool 13 the traversing mechanism is set in motion and as it moves to the left a pin 26 on a disc 16 catches the wire and pulls it off the pin 25 so that the wire adopts the position shown in broken lines. Since the wire no longer passes over the pin 25 the motion of the reciprocating mechanism fails to carry the wire on to the spool 13 and the layering of the wire is restricted to the spool 12. The disc 16 may be integral with or fixed to the spool 13 or it may be a separate part interposed between the flange of the spool 12 and the end of the spool 13. When the winding of the spool 12 is completed, the two spools are removed and the wire is cut at some point between the periphery of the flange of the spool 12 and the portion of wire coiled on the spool 13.
