Abstract: 922,098. Electrodeposition of gold. WESTERN ELECTRIC CO. Inc. July 7, 1960 [July 28, 1959], No. 23739/60. Drawings to Specification. Class 41. Metallic surfaces, such as made of copper, brass, nickel or its alloys, e.g. " Kovar " (Registered Trade Mark), zinc, zincated aluminium or lead-tin solder-dipped cooper, are electrolytically gold plated, such as for printed copper circuitry or ornamental purposes, by immersing them in a bath of cyanide-free aqueous solution containing gold citrate (tribasic aurous citrate), the concentration of gold preferably being from 1 to 50 g/l., and in which the surfaces are biased cathodic with respect to an immersed electrode, which may be an insoluble anode of stainless steel, gold or carbon. The solution may be made initially of sodium and/or potassium gold cyanide, e.g. 20 g/l. of commercial NaAu(CN)  2 , with citric acid and/or a salt thereof such as of ammonium, potassium or sodium, e.g. 20-100 g/l. of anhydrous (NH 4 ) 2  HC 6 H 5 O 7 ), and boiled to drive off all hydrocyanic acid. Alternatively, the cyanide-free solution may be made using other aurous salts such as AuCl, AuBr, AuI, Au 2 O, Au 2 S and AuOH. The plating is preferably carried out in a bath of temperature at least 45‹ C. using a current density of at least 1 amp/sq. ft., and with a solution of pH at least 4, and not more than 8 for plating adhesively bonded, e.g. through phenol formaldehyde containing a vinyl compound, copper circuits; the pH may be controlled by the addition to the solution of HCI, H 2 SO 4 , KOH, NaOH or NH 4 OH. The solution may also be prepared by anodic dissolution using a gold anode and chloride ions, e.g. HCl or NH 4 Cl. Up to 100 g/l. of a conducting salt such as ammonium sulphate and up to <SP>1</SP>/10 g/l. of an additive to reduce grain size may be added. For hardness, alloys of gold, such as Au-Pt, Au-Rh and Au-Ag, may be plated whereby the alloying ingredients, generally less than 2%, are added to the solution in the form of diamino nitrite (for platinum), sulphate (for rhodium) or cyanide (for silver).

Title: Improvements in motor vehicle controls
IPC: G05G5/06
Filed: 1937-08-31
Abstract: 498,932. Brakes. JACKSON, M. B. and LUMBERS, J. H. Aug. 31, 1937, No. 23844. [Class 103 (i)] A lever acted upon by a spring or other means tending to apply the brake of a vehicle &c. is held in the " off " position by manual pressure on a member movably mounted on the lever, release of this pressure releasing the holding means to permit application of the brake. The movable member may carry a further manually operable locking member which also controls the power supply. A spring 23 tends to operate a lever 1 to apply brakes through a hydraulic transmission 26. The lever has pivoted thereon at 4 a member 6 having side parts 5 embracing the lever and carrying a roller 8 which when pressure is applied to a foot plate 21 secured to the member 6 engages a recess in a fixed part 14 as shown and so holds the lever in the off position. Upon relieving the pressure the roller is disengaged and runs on the under surface of part 14 as the lever moves to apply the brake. The lever is returned by pressure on the plate. To permit removal of the foot without application of the brake, a toeplate 9 can be rocked laterally on the member 6 to engage a projection 29 with the lever 1 to hold the roller 8 in the recess. The part 19 of the toe-plate 9 engages an arm 20 on a shaft 30 mounted on the floor part 11 and connected to the throttle which is thus opened by movement of the plate 9 in the opposite direction to that which engages the projection 29.

Patent GB-406369-A (GB)
Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/52
Filed: 1932-08-26
Abstract: 406,369. Fluid - pressure brakes. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Farmer, C. C. ; 7008, Thomas Boulevard, Pittsburg, U.S.A.) Aug. 26, 1932, No. 23944. Convention date, Oct. 8, 1931. [Class 103 (i).] Triple valves for compressed air brakes of the kind comprising a valve-operating piston subject on its sides respectively to the pressures in the train-pipe and a control chamber, communicating with the auxiliary reservoir which supplies the brake cylinder are provided with means for venting the control chamber when the train-pipe pressure is raised after an application of the brakes, whereby the valve is positively returned to the release position. A triple valve of the retarded release type is shown in the full release position, in which the brake cylinder 2 is open to the exhaust port 33 by the passages 31, 32, but if there is a rapid rise of train-pipe pressure the spring stop 12 with which the valve member 23 contacts is moved to the right so that the brake cylinder exhaust takes place through the restricted passage 36. The stem 14 of the piston 6 has limited sliding movement by means of a pin and slot 25, 24 relatively to a member 16 between which and the piston 6 a spring 27 is disposed and the member 16 has limited sliding movement with respect to the side members 26 of the main slide valve 8. The chamber 40 below a diaphragm 38 adapted to cut-off the auxiliary reservoir 3 from a passage 39 connected to the main valve chamber is connected by passage 43 to an exhaust passage 35. When the train-pipe pressure is reduced, the graduating valve 9 is first moved to uncover the passage 30 and the main valve 8 is then moved by engagement of the part 23 of the member 16 with the members 26 to register the passage 30 with the passage 31 to supply the brake cylinder. If the train-pipe pressure reduction is stopped the piston with the valve 9 returns sufficiently to lap the supply passage 30 and the part 17 of the member 16 again contacts with the members 26 of the valve 8. If now the train-pipe pressure is slightly raised, the friction of the valve 8 prevents movement of it and the member 16 and the piston 6 with the valve 9 moves slightly to the right compressing the spring 27 and uncovering the port 34 which registers with the passage 35 so that the valve chamber exhausts through this passage. Further since the chamber 40 beneath the diaphragm 38 is now also connected to the valve chamber through the passages 43, 34, the diaphragm by the action of the spring 40 cuts off the connection of the auxiliary reservoir 3 with the valve chamber through the passago 39. The parts are thus promptly returned to the release position shown. The device 38, 40 for cutting off the auxiliary reservoir when the valve chamber is vented may be dispensed with.
