Title: Improvements relating to reversing valves
IPC: F01L15/08
Filed: 1960-06-21
Abstract: 891,052. Liquid-pressure engines. SHELL INTERNATIONAL RESEARCH MAATSCHAPPIJ N.V. June 21, 1960 [June 23, 1959], No. 21728/60. Class 69 (2). A valve for automatically reversing the supply and discharge of pressure-liquid, respectively, to and from the working spaces 12, 13, Fig. 1, of a double-acting cylinder 1 slidably mounting a piston 2, comprises a stationary housing 8 having ports 18, 20 connected to the spaces 12, 13, respectively, a pressure liquid supply port 19 and exhaust ports 17, 21 and a slide valve member 22 having lands 23, 24 controlling the ports. A control member 7 connected to the piston 2 through a piston-rod abutment 4, levers 5, 6 and a link 11, is formed with a piston 26 dividing the interior of the valve member 22 into spaces 27, 28. A control-rod 25 extending on either side of the piston 26 slides in extensions of the housing 8 comprising pump cylinder spaces 36, 37 and the reduced diameter ends of the rod 25 provide annular pump piston surfaces 38, 39. The rod 25 is formed with a channel 40 and groove 31 connecting the space 36 at all times with the space 28 and a channel 41 and groove 30 connecting the space 37 at all times with the space 27. Grooves 32, 33 in the valve member 22 co-operate with the grooves 30, 31, respectively, to connect the spaces 27, 28 to the exhaust ports 17, 21. In the position shown in Fig. 1, the valve member 22 is supplying pressure liquid to the working space 13, the piston 2 is moving leftwardly, the abutment 4 has begun its engagement with the lever 5. The pump cylinder space 36 and valve space 28 at this time being connected to pressure liquid supply through a port 29. On further leftward movement of the piston 2, the control member 7 together with its piston 26 moves rightwardly and when the piston 26 passes the port 29 the connections to the pump cylinder spaces 36, 37 and the valve spaces 27, 28 are reversed so that the spaces 27, 37 are now connected to pressure and the spaces 28, 36 to exhaust, the valve 22, however, still continues to supply the working space 13. As the piston 2 moves further leftwardly and hence the piston 26 further rightwardly, pressure liquid in the pump cylinder space 37 is pumped into the space 27 to fill the increased volume created by the rightward movement of the piston 26. The valve member 22 then begins its leftward movement whilst the piston 26 is still moving rightwardly so that no delay occurs in reversing flow to the working cylinder 1. The annular surfaces 38, 39 and the channels 40, 41 prevent additional displacement of the piston 2 and the abutment of the piston against the cylinder ends irrespective of the speed of the piston 2. The higher the speed of the piston 2 the shorter will be the time required to reverse the valve member 22. Specification 858,265 is referred to.

Title: Improvements in rolling contact bearings for use with oscillating members
IPC: F16J1/14
Filed: 1925-08-31
Abstract: 242,600. Jokers, H. Nov. 6, 1924, [Convention date]. Rolling-friction bearings.- The contacting faces 13, 14 of an oscillating rolling-contact bearing are pre.vented from lateral slip by toothed mechanism 15, 16 and they are held in mutual contact when tensional forces arise by a rigid member 17. The toothed mechanism may comprise more than one tooth and remains in engagement throughout the entire oscillation. The bearing faces 13, 14 may be cylindrical, having the centres at the centres 18, 19 of the pivot pins connecting the member 17 to the oscillating members 1, 2 respectively. For small oscillations one bearing face, 14, may be flat and any point, such as the pivot pin 19, on the member 2 may be guided in a slot in a member integral with or attached to the member 1. As shown, a point 21, Fig. 2, on the member 2 and which traces, approximately a straight line is guided by a member 22 slidable in a slot 23 in the member 1. Applied to the gudgeon pin bearing of a piston the member 1, Fig. 4, may rock on the pin 41 to adjust itself to the plane of oscillation of the member 2 which forms part of the connecting- rod. The toothed parts are formed at each side of the members 1, 2, to prevent twisting of the latter out of the plane of oscillation. In a modification, the bearing faces are shaped so as to dispense with the tension member 17. The member 1 has additional faces 35, 36, Fig. 6, engaging inclined faces 31, 32, on the member 2. As shown, the member 2 is formed as a pin 51 mounted in a fork so as to adjust itself by rocking in a plane at right-angles to the plane of oscillation of the members 1, 2.

Title: Improvements in or relating to the draught control in stoves, boilers and like heating apparatus
IPC: F23N3/04
Filed: 1933-08-03
Abstract: 410,991. Closed solid-fuel stoves. BELL'S HEAT APPLIANCES, Ltd., and SCOTT, C. L., 157, Queen Victoria Street, London. Aug. 3, 1933, No. 21840. [Class 126.] The opening of the fire or ash-pit door of a stove, which admits air tending to increase the rate of combustion, is caused also to admit a check draught to the flue by means operating without moving parts other than the door itself. In the heat-accumulating cooking stove described, the ash-pit door 1 covers also the inlet 11 to a duct 12, 13, 14 by which the check-draught passes to the outlet flue 4 when the door is opened. A small opening 16 in the door, covered by a hood 17, allows a restricted supply of air to the flue when the door is closed ; this restricted air supply, being heated in the duct before delivery to the flue, helps to maintain a draught. Alternatively, the door when closed may be spaced from the inlet 11 sufficiently to maintain the restricted air supply. The normal air supply to the ash-pit is thermostatically controlled. In a modification, an upward extension of the ash-pit door covers the inlet to a duct leading to the base of an annular flue surrounding the cylindrical fuel hopper, thus supplying the check-draught immediately above the fire. Where both fire and ash-pit doors are provided, they may control parts of one air inlet, or separate inlets.

Abstract: 423,599. Valve circuits. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, and SCHLESINGER, K., 39, Friedrichstrasse, Friedrichshagen, both in Berlin. Aug. 5, 1933, No. 22056. Convention date, Aug. 6, 1932. [Classes 40 (iii) and 40 (v)] Electric impulses of constant shape and amplitude are produced independently of the shape of received signals by the use of a relaxation oscillation circuit 1, 3, 4. The condenser 3 is charged through the resistance 4 and discharged through the gas-discharge tube 1 when the potential on the control grid 6 exceeds the ignition potential. To synchronize a television cathode-ray receiver, the grid is connected to a transmission line 10 through a condenser 22, which is charged through a diode 18 to a potential, which is kept below the maximum peak signals by a leakage resistance 19, as described in Specification 420,679. The short relaxation oscillation, applied to a lead 24, is selected by a filter 27, 28 for application to line-control apparatus LS. The transmitted picture is surrounded by a dark frame so arranged that at the end of each picture no signal occurs for several scanning-lines. Owing to amplitude reversal in the system, a maximum potential remains on the control grid during this interval, and continuous relaxation oscillations take place. The mean potential of the condenser 3 is thus lowered for a sufficiently long period to pass through a filter 25, 26 to the image-control apparatus PS.
