Title: An improved tubular steel pit prop
IPC: E21D15/18
Filed: 1932-01-06
Abstract: 381,795. Pit props. BARKER, R. E., Aysgarth, Warren Avenue, Knottingley, Yorkshire. Jan. 6, 1932, No. 368. [Class 20 (ii).] A tubular steel pit prop c, is reinforced by steel strips l which are arranged longitudinally in the tube and are interspaced by a lighter material such as wood w. The strips extend from an upper wedge-shaped disc d to a plug b secured to the base of the tube. The tube is cut away at e to accommodate the disc d and a wedge k engaging therewith. The upper edge of this wedge engages with a vertically movable head a which fits into the upper end of the prop and extends between the disc d and the roof of the pit. The overall length of the prop can thus be adjusted by altering the position of the wedge, the increased or decreased compressional stresses thus produced being taken by the strips l. The lower end of the prop fits into a tube f having an aperture g through which loose coal can be introduced, when the two tubes c, f are extended, to vary the overall length of the prop.

Title: Improvements in methods of making seamless tubes
IPC: C25D1/02
Filed: 1947-01-06
Abstract: 620,106. Making tubes by electrodeposition. UNITED STATES RUBBER CO. Jan. 6, 1947, No. 401. Convention date, Jan. 19, 1946. [Class 41] [Also in Group XXII] A method of making a seamless tube having a smooth inner surface comprises electrodepositing a flash film of copper over a mandrel having a smooth exterior surface, electrodepositing a film of lead over the copper and another flash film of copper over the lead and then electrodepositing a metal jacket to form the required tube, heating to melt the lead and then drawing the deposited tube off the mandrel. The melted lead acts as a lubricant to assist the withdrawal of the tube, while the copper flashes prevent the lead alloying with either the tube or the mandrel. After the tube has been deposited, its outer surface may be machined while it is still mounted on the mandrel. A nickel or silver lined tube may be produced by electrodepositing a layer of nickel or silver over the second copper flash before depositing the tube metal, which is usually iron. A double-tapered tube may be formed on a mandrel as shown in the Figure, comprising parts 18 and 19 coupled by a screw 20. The copper, lead and copper films are indicated at 22, 24 and 23 respectively. Tubes produced by this method may be used in microscopes, field glasses, wave meters and the like. The tube may be of non-circular cross-section.

Title: Improvements in Fluid Motors and Pumps.
Inventor: SUNDH AUGUST
IPC: F04B49/24
Filed: 1918-01-08
Abstract: 124,007. Sundh, A. Jan. 8, 1918. Eccentric-actuated pumps; multiple-acting piston pumps; balancing parts; regulating delivery by by-passes; relief devices; springs; stroke, varying; valves, arrangement of.-In an eccentricactuated pump, the eccentric 26 is adjusted transversely of the driving shaft 4 bv means of fluid pressure for the purpose of varying the stroke of the plungers 5. The shaft is bored to form a chamber 32 in which a piston 31 is moved by the fluid pressure admitted to either end of the chamber by ports 34. The piston carries a rod 30 engaging opposite sides of the eccentric, so that, when the piston is moved, the eccentric is moved in the same direction. The pressure-fluid is admitted to the chamber 32 from an accumulator 95 by means of a hunting-valve 71 controlling ports 89, 90 connected by pipes to annular chambers 42, 43 communicating with the ports 34 by means of passages 35, 36 in the shaft. The eccentric 26 is balanced by means of a weighted member 46 slidably mounted on the shaft and adapted to be moved in the opposite direction to the concentric by means of a rack-and-pinion connexion between it and the eccentric. Two springs 50, 51 enclosed between the opposite faces of the member 46 and the shaft resist the centrifugal movement of the member 46, and two springs 65 in a casing attached to the eccentric resist the centrifugal movement of the eccentric. A rod 53 engaging opposite faces of the member 46 has a wedge surface 55 engaged by a rod 56, which is forced against it by a spring, so that, when the member 46 moves across the shaft, the rod 56 is moved axially and actuates a yoke 77 connected by links 80, 81 to the rod of the valve 71. This movement returns the valve to the closed position. The valve is opened to adjust the eccentric by means of two sets of electro magnets 86, 87 for moving the valve in opposite directions. The magnets in each set are energized successively by means of a multiplecontact switch so as to exert an increasing turning movement on a spindle 84 carrying a lever 83 connected to the valve-rod by links 82, 81. The accumulator 95 is fed by a pump 101 actuated by an eccentric on the shaft 4 and mounted in a sump in the pump casing. When the level of liquid in the sump is high, a float opens a switch of an electro-magnet holding a by-pass valve open, thereby closing the by-pass valve and allowing the pump to force fluid to the accumulator. When the level falls, the float closes the switch and thereby opens the by-pass. Each pump chamber 7 communicates alternately with annular inlet and delivery chambers 11, 13 in the head of the pump casing. The inlet and delivery are controlled by a piston valve 10 actuated by an eccentric 19 on the shaft 4. Relief valves are arranged between the chambers' 11, 13. The invention is applicable to motors of the same type.

Title: Improvements in or relating to electrostatic precipitator power supply equipment
Inventor: BROOKS NORMAN COLSTON
IPC: B03C3/68
Filed: 1964-01-06
Abstract: 1,017,351. Control systems for electrostatic precipitators. STANDARD TELEPHONES & CABLES Ltd. Jan. 6, 1964, No. 556/64. Heading H2H. Power supply equipment for electrostatic precipitators includes means for periodically increasing the voltage applied thereto and further means responsive to arcing in the precipitator to effect a momentary reduction or disconnection of the applied voltage and thereafter to re-instate the supply voltage at a value lower than that at which the arcing occurred. An electrostatic precipitator EP is supplied from an A.C. source by way of a regulator DR, driven by a reversible motor RM, a contactor CR and a rectifier RC. Initially a time switch TS is operative to close contact ts1 once or twice a minute to energize the motor RM to drive the regulator DR in a direction to increase periodically the voltage applied to the precipitator EP during which operation a capacitor C charges by way of a rectifier MR2. On the occurrence of arcing in the precipitator the capacitor C discharges by way of a rectifier MR1 and whilst discharging energizes the relay winding RL1/3 to operate its contacts rl1À1 ... rl1À3. During the discharging period of the capacitor C therefore the contactor CR is de-energized to disconnect the precipitator from the supply; the circuit to the " raise " field R of the motor RM is broken and the circuit to the " lower " field L of the motor is completed by way of a relay winding RL2/2, thus the motor RM drives the regulator DR in a direction to decrease the voltage output therefrom. Since the relay RL2/2 only holds in for the period whilst the motor RM is starting the regulator DR is only operative to decrease the voltage setting a small amount. When the capacitor C completes its discharge relay RL1/3 is de-energized whereupon the contactor is re-energized to connect the precipitator to the supply at the lower voltage setting, the " lower " field L is de-energized and the " raise " field R is re-energized and the cycle repeats. Push-buttons PB1, PB2 allow manual control of the apparatus. In other embodiments complete disconnection of the supply by the contactor CR is replaced by a partial reduction in the supply voltage using a tapped transformer or a series reactor.
