Title: Improvements in the production of smooth electro-plated sheets or the like
IPC: C25D5/12
Filed: 1934-01-12
Abstract: 424,724. Electroplating. ASSOCIATED APPLIANCES, Ltd., 7, St. James's Street, Pall Mall, London, DEUTSCH, S., and DEUTSCH, H. R., 17, Untere Weissgarberstrasse, Vienna. Jan. 12, 1934, No. 1230. [Class 41] A metal sheet is bared and roughened before electroplating and after plating is heated to the point of softening the deposit and then rolled cold to elongate the coated material; it may be finally annealed. In an example, iron sheets are freed from oxide film by pickling and then roughened by sand-blasting. Copper is then deposited at high current density from a flowing electrolyte to a thickness 10-25 Á. Nickel is then deposited at high current density to a thickness 10-30 Á. The sheets are afterwards cleaned and annealed in a protective atmosphere at 700-900‹ C., diffusion of the metals also taking place. The sheets are then rolled cold to an elongation of 30 per cent and subjected to a second heat treatment similar to the first. When chromium is substituted for nickel, an intermediate copper coating of not less than 20Á should be provided. Other highly ductile metal, such as silver, may be employed instead of copper. Specification 282,748, [Class 41], is referred to.

Title: Improvements in rotary compressed air engines
IPC: F01C1/18
Filed: 1948-01-15
Abstract: 652,637. Rotary engines. ETABLISSEMENTS FOURNIER & MOUILLON. Jan. 15, 1948, No. 1271. Convention date, May 28. 1947. [Class 110(ii)] Two gear-wheel engines operating in series have a. gear 8 meshing with gears 6, 7, full working fluid pressure acting on parts of the gear peripheries, and working- fluid at a lower pressure on other parts of the peripheries. If desired, valve means may be actuated to supply the working-, fluid at high pressure to all parts of the engines, 6, 8:7, 8. The engines may be reversed by moving a lever 85 to rotate plug valves 80, 31 as one unit and reversing the direction of flow of the fluid. The working fluid may be compressed air operating at pressures of 72 lbs. and 36 lbs. per square inch in the respective engine stages. The fluid at high pressure enters a space U and, under control of a valve 49 flows to a space T, and port 131 to the inlet A. As shown by the arrows, Fig. 2, fluid drives gears 6, 8 and passes through ducts B. C. These lead the fluid, at half-pressure to ducts.D, V, F and port 124 to drive gears 7, 8 and ultimately flowing through G, H to atmosphere. The valve 31, for forward drive of the engines, has A as intake and H as exhaust, and the valve 80 intake through the space F and exhaust through the space G. To admit high-pressure fluid to the space V, and thus to the second engine, a lever is moved to rotate a cam 97 and open a valve 94. The admission valve 49 is controlled by a speed governor comprising weights 42, pivoted at 43 to the end of the shaft 19. The heel portions 44 engage a thrust bearing 46 to move the shaft 48 and thus the valve 49 to vary the overlap of fluid-admission ports 52, 51. Within a bush 56 a slide-block 60 is engaged by a spring 55 which follows the slide-block in its rotational and longitudinal movements through a screw-thread formed on the block. An adjusting knob 70 acts through a key 69 to re-position the slide-block. A spring 81 presses apart the valves 31, 80 on to their conical seats Several modifications of the ducts between the inlets and the intermediate admission ports are described in the Specification. A servo-motor comprising a radial vane in a semi-circular cylinder, Fig. 12, (not shown), may be acted on by fluid under pressure which is admitted by a rotary valve under manual control, the motor actuating a rotary valve such as 80.

Title: Improvements in or relating to vapour generators
IPC: F22B37/26
Filed: 1965-01-12
Abstract: 1,077,783. Steam generators; heat exchanger tubes. BABCOCK & WILCOX CO. Jan. 12, 1965 [Jan. 13, 1964], No. 1337/65. Headings F4A and F4S. A steam generator has primary separating means such as baffles 30 for separating steam from a steam-water mixture and a scrubber 10 comprising closely spaced plates 45 heated by tubes 40 to evaporate any moisture thereon. The baffles 30 are in three sections extending throughout the length and width of the steam drum 12 each section comprising three perforated plates beneath the liquid level 14. The moist steam passes to the scrubber 10 the heating tubes 40 of which are supplied with superheated steam from headers 41. The plates 45 are secured to the tubes 40 and have horizontal corrugations so that the steam is subject to changes of direction and the moisture and any entrained solids are deposited on the plates and the steam passing through the outlet 23 is dry. Line and end closure plates 55, 60 prevent flow of steam to the outlet 23 except through the scrubber. Spray pipes 70 are provided for intermittent back-washing of the deposits from the plates 45 and the exposed portions of the tubes 40. The heated scrubber may be contained in a separate pressure vessel. Instead of being parallel and corrugated the plates may be joined at their edges in pairs to form flow passages with converging and diverging walls. The scrubber may act as a desuperheater, e.g. in marine plant. In a modification the baffle 30 is replaced by a number of cyclone separators of the type shown in Speci fication 740,111. Two heating and scrubbing devices may be mounted one above the other. The scrubbers may be heated by electrical resistance heaters instead of by steam.

Abstract: 1,177,615. Ion-exchange. KURITA WATER INDUSTRIES Ltd. 10 Jan., 1967 [10 Jan.. 1966; 14 Jan., 1966], No. 1372/67. Heading B1J. An ion exchange treatment takes place in column 1 with regeneration of the displaced exchanger in column 2. Regenerated exchange fills column 1 with liquid for treatment fed to column by valve 25 and leaving by valve 26. For regeneration of spent resin valve 8 and 27 are opened and resin below strainer 3' falls into measuring tank 6 being replaced by treatment liquid. Valves 25 and 26 are closed and 7 is opened. This causes a piston-like movement of resin downward from hopper 5 controlled by plate 4. Valves 7, 8 and 27 are closed and treatment is resumed. Valve 35 is kept open and resin is transferred by water under pressure in line 24 to the regenerator hopper 11. The mechanics of the process are now repeated in the regenerator 2 with the addition of a concurrent washing step through pipes 22 and 33. The amounts of resin transferred are determined by the size of the measurement tanks and the predetermined numbers of transfers.

Abstract: 983,527. Protective arrangements. UNITED STATES ATOMIC ENERGY COMMISSION. Jan. 14, 1963 [April 2, 1962], No. 1579/63. Heading H2H. A superconducting solenoid comprises a solenoid winding P housed in a vessel 1 filled with liquid helium, a secondary winding S being closely linked magnetically with the solenoid winding P so that the energy to be dissipitated when the magnetic field collapses should the superconducting solenoid become normal is dissipated in the external circuit R 2 , 11, 9 associated with the secondary winding S. For relatively small solenoids the supply circuit to the winding P omits the resistor 7 and the relay 13, 14, all three switches 3, 11, 12 remaining closed during operation. With large solenoids the supply circuit is as shown in Fig. 1 wherein the switch 12 is initially closed and then opened after relay coil 14 has become energized by the supply current to close contact 13. If the solenoid now goes normal, relay 14 falls out to open contact 13, thus inserting resistor 7 in the supply circuit to assist in the dissipation of the energy in the solenoid. Specification 983,528 is referred to.

Abstract: 788,798. Electric fluid flow meters. HOBSON, Ltd., H. M., and HULLEY, B. J. Dec. 23, 1955 [Jan. 19, 1955], No. 1624/55. Class 40 (1). Apparatus for determining the mass flow of liquid through a pipe comprises a rotating vane flow meter producing electrical pulses at a rate determined by the liquid flow and a counterbalanced float in the liquid associated with a potentiometer adjusting the mark-space timing of a multivibrator controlling a gate for the electrical pulses, whereby the gate is closed for a proportion of the time dependent on the liquid density, and the resultant pulse train is integrated to give the mass flow of the liquid. The potentiometer condition is also automatically compensated for the effects of acceleration on the pipe, by means of a pendulum. As shown, a float 11 (Fig. 1) and attached balance weight 12 pivoted at 14 are located in a pipe 10 carrying a liquid, the resultant position of the float being determined by the density of the liquid, and being indicated by the slider 13 of a potentiometer 15 carried by a pendulum 16 which modifies the position of the slider on the potentiometer in accordance with any external acceleration. The apparatus is associated with a flow meter of the rotating vane type, having a magnet on one blade, producing electrical pulses in a stationary solenoid, the pulses being sent through an amplifier and shaper 24 (Fig. 6) to the grid 32 of a gate valve 25, the cathode 35 of which is connected via cathode follower 30 to a multivibrator 29 whose mark-space ratio is determined by the position of slider 13 on potentiometer 15. Thus during the space period of the multivibrator 29 the gate 25 passes the flow meter pulses to a counter which indicates the mass flow of liquid through the pipe. A ratemeter fed by the gas 25 also indicates the mass rate of flow of liquid. Specification 752,496 is referred to.
