Title: Method of electro plating on aluminum and its alloys
IPC: C25D5/44
Filed: 1955-04-27
Abstract: 770,503. Electroplating on anodized aluminium. MACLEAN, W. D., and CLELAND, D. April 27, 1955, No. 12203/55. Class 41. Prior to electroplating, the oxide film produced on aluminium or aluminium-base alloys is subjected to the action of an aqueous solution consisting of sodium hydroxide and sodium silicate. Preferably after degreasing, e.g. with caustic soda, and pickling in dilute hydrofluoric acid, anodizing is effected by A.C. or reversing D.C. at 25 amps/sq. ft., using an aqueous solution of oxalic acid and the oxide film is then treated with a solution containing 8 ozs, caustic soda and 6 ozs. sodium silicate per gallon. Plating with any metal may then be effected from a cyanide bath while silver, copper, zinc, cadmium, tin, iron, cobalt, and nickel or any metal having a soluble fluoride may be deposited from a fluoride-contaiing bath. Typically, boric and hydrofluoric acids are mixed and the resulting fluoboric acid is neutralized with triethanolamine to form a first solution, while a second solution is formed from nickel (or other specified metal) carbonate. hydrofluoric acid and a small amount of ammonium fluoride, the two solutions being mixed to form the plating bath and the pH being adjusted with hydrofluoric acid or triethanolamine. Alkaline baths may be heated and so operated at high current densities but acid baths remain clearer. Bright ductile flexible soft deposits are obtained, especially with nickel.

Title: An improved pressure relief valve
Inventor: LAMB JOHN
IPC: F16K17/04
Filed: 1957-04-16
Abstract: 827,481. Relief valves. LAMB PUBLICATIONS & INVENTIONS Ltd., J. March 18, 1958 [April 16, 1957], No. 12378/57. Class 135. A disc 4 of a relief valve for electric furnaces &c. is attached to a plunger 6 which is slidable within a cylinder 14 and has an extension 26 for operating a valve, such as a spring-closed ball valve 27, to control the admission of loading air to the cylinder to close the relief valve, and means, e.g. shuttle valve 23, sliding between shoulders 21, 22 on a hollow part of the plunger to control the radial ports 24, and radial ports 25 controlled by the position of the plunger in the cylinder are provided to delay the action of the loading air to enable the relief valve to fully open. An inner extension of the plunger may be guided by a spider 8, attached to the wall of the furnace, and may be shielded by tubular members 11, 12, 13. In the event of an explosion as the valve disc lifts, the shoulder 22 of the plunger abuts the shuttle valve 23 to allow air admitted to the cylinder by the plunger extension 26 displacing the ball 27 to escape freely to atmosphere via ports 24, the tubular part of the plunger and ports 25. When ports 25 are covered by the cylinder wall, pressure builds up in the cylinder at first to arrest motion of the valve disc and thus force it to its closed position: at this time the shuttle valve 22, due to friction with the cylinder wall, is abutted by shoulder 21 and the outlets 24 are closed until the valve disc again reaches the closed position shown. As described, the furnace works under vacuum and the valve disc is held closed by the pressure difference, but a spring of suitable strength may be added to hold the valve disc closed under normal working conditions where a positive pressure exists in the furnace.

Abstract: 865,470. Valves. HILL PORTER (NEWCASTLE) Ltd., and TALBOTT, A. C. April 16, 1959 [April 18, 1958], No. 12437/58. Class 135. An hydraulic pressure-relief valve designed to avoid cavitation e.g. when used in a yielding hydraulic prop, comprises a valve body in which a spring-loaded valve member is pressed against a sharp-edged circular hole or a conical surface in a valve seating, while attached to the valve member is a flow-spreader plate having a diameter at least twice the diameter of the contact circle of the valve member with its seating or the diameter of an open hole through which the liquid passes immediately before the spreader plate and spaced above a part of the valve body to form a thin space through which the liquid passes when the valve is open into a larger space above the spreader plate which is pressurized by an outlet restriction or by the spring-loaded valve member itself to prevent cavitation in the valve. In one embodiment, Fig. 1, the spring- loaded ball valve member d is carried by a flow spreader disc g spaced above a part of the valve body a to form a thin space h, the relieved liquid from an inlet c passing the disc into a larger space i above the plate and thence out through a pressurizing leak valve j, a pressure difference thereby erected across the disc tending to augment the spring load and re-seat the valve when the pressure at the seat orifice e<SP>1</SP> falls slightly below that required for opening the valve. Pressure surges lifting the pressurizing valve j cause a leaky plunger part of this valve to close slots k so as to provide only a slow leak. In another embodiment, Fig. 3, a flow spreader plate q placed slightly above an open flow orifice n<SP>1</SP> of an inlet n carries a spring-loaded conical valve-member o which obturates a seat opening leading out of the larger space s above the plate, so that the relief valve member o itself forms a restriction pressurizing the space s and avoiding cavitation beneath the spreader plate q.

Abstract: 858,281. Electric tests. LEGG Ltd., R., and SCHREIBER, P. Q. R. April 18, 1957 [April, 24, 1956], No. 12564/56. Class 37 The moisture content of a moving band of material, for example tobacco, is determined by successively compressing portions of the material to a controlled degree, causing the -material in the compressed state to complete an electric circuit to produce a succession of electric pulses varying in magnitude with the moisture content, integrating the pulses and using the integrated output to control an indicator to indicate the average degree of moisture present in successive regions of the band. In the arrangement shown in Fig. 4 the stream of tobacco is fed between rollers 2, 3 one of which is fixed and the other of which is mounted on a pivoted lever so as to compress the tobacco. Electrodes 4 are mounted in the face of roller 2 and are connected to contact makers carried on the end of the roller shaft. A third contact maker 13 is also provided. When the electrodes 4 are bridged by the tobacco, contacts 6, 7 and 13 (Fig. 10) are made and condenser 11 charges or discharges through resistor 13 according to the moisture content of the tobacco to average the effect of a number of pulses and control the grid potential of triode 9. The moisture content is indicated by meter 10 in the cathode circuit. The rollers may be mounted eccentrically or may be cam shaped so that they only pinch the material at intervals. Three contacts may be mounted in the face (Fig. 9) of the roller the outer ones being divided into a number of sections 41, 42. The arrangement here is that the tobacco is included first in the condenser charging and then in the discharging circuit as the roller rotates so that errors due to varying width of tobacco are eliminated. A winnowing arrangement may be used to remove the effect of the compression of the tobacco.
