Title: Improvements in or relating to servo-assisted operating mechanism
Inventor: EDGE STANLEY HOWARD
IPC: B60T13/24
Filed: 1950-10-30
Abstract: 689,334. Fluid pressure brakes. CLAYTON DEWANDRE CO., Ltd. Oct. 8, 1951 [Oct. 30, 1950], No. 26421/50. Class 103 (i). In a pneumatic servo unit for hydraulic pressure systems, particularly brake systems, of the type in which the output pressure from the hydraulic boost cylinder 32 is arranged to react upon a valve device 4 which controls the inlet and exhaust of fluid to and from the servocylinder 27, the piston 29 of the servo-cylinder has a single imperforate piston-rod 28 which extends into and acts as the only displacement member for the liquid in the hydraulic boost cylinder. As shown in Figure 2, the valve device 4 has a piston 5 to the top of which hydraulic pressure is applied by the actuator or master cylinder 2. The piston 5 operates through a pivoted lever 13, piston valves 9 and 10 controlling the application of vacuum or fluid pressure at connection 19 and the exhaust to atmosphere at connection 21 of the pressure in the servo-cylinder. A pipe 34 led led off the pipe 33 transmitting the output from the boost cylinder 32 to the brake cylinders, applies the brake cylinder pressure to a smaller piston 6 reacting against the piston 5, so that the hydraulic line pressure is always kept proportional to the pedal effort. A modified arrangement in which the valve device 4 is fitted directly adjacent the servo-cylinder is also described.

Title: Improvements in or relating to gas calorimeters
IPC: G01N25/46
Filed: 1939-09-22
Abstract: 532,517. Calorimeters. BOYS, Sir C. V. Sept. 22, 1939, No. 26447. [Class 97 (iii)] In gaseous fuel calorimetry suitable for testing a small quantity of gas, a pre-determined total quantity of the gas, fed positively at a pre-determined rate, is burnt in a current of air which is induced by controlling positively the rate of flow of the effluent gases, the heat is absorbed in a pre-determined quantity of a calorimetric liquid and the rise in temperature noted. Two interconnected bottles 23, 27 one 23 containing the measured quantity of gas above the datum water line 25<SP>1</SP> while the other contains water. The bottles are suspended by a wire 22 passing over a pulley 21. Rotation of this pulley 21 lifts the bottle 27 and lowers the bottle 23 to discharge the gas through tube 29 to a burner 31. The pulley 21 is rotated by means of another pulley 17 over which passes a wire 16 connected at one end to a counterweight 18 and at the other to a float 14 which rises in a vessel 10 according to the inflow of water through tube 9 from an aspirator bottle 3. The gas is burnt in a calorimeter comprising a tube 33, coil 34 and tube 35 placed in a vacuum vessel 46 containing water the fixed temperature of which is ascertained by a thermometer 43. The effluent gases pass through a tube 38 to the bottom of the aspirator bottle so that the rate of flow of the air through the coil 34 to support combustion is under the positive control of the rate of outflow of the water through tube 9 to the vessel 10. To recharge, the tap D is closed and tap E from the gas supply is opened, the water is pumped back from vessel 10 to the aspirator bottle 3 through tube 12, 13, 7 by a suction pump 39, causing the float 14 to fall and consequently the bottle 27 to be lowered and the bottle 23 to be raised to fill the latter with gas down to the datum line 251

Title: Combustion system for diesel type rotary piston engines
IPC: F02B55/14
Filed: 1962-07-12
Abstract: 999,561. Rotary piston diesel engines. GANMAR DIESEL ENGINE CO. Ltd. July 12, 1962 [July 13, 1961], No. 26850/62. Heading F1F. A direct-injection, rotary piston, Diesel engine comprising a housing having a two-lobe epitrochoidal inner wall surface 1, Fig. 1, and a triangular rotary piston 5 having peripheral faces interconnected by sealing edges 9 which have sliding contact with the surface 1, includes in each peripheral piston face, a combustion cavity 17 isolated from the side faces of the piston with its major portion forward of the mid-point of the peripheral face. A fuelinjector 15 is located so that a sealing edge 9 passes the injector immediately after the exhaust port 13 is opened. The pressure in the compression chamber II, Fig. 3, is then greater than in the expansion chamber I, and in consequence a jet of air forces itself past the narrow gap at the tip of the injector to cool the tip and prevent the deposit of carbon thereon. A passageway 19 at the trailing end of each cavity 17 connects sub-chambers of the compression chamber as the piston approaches its "top dead centre" position, and in doing so gradually decreases in cross-sectional area to increase the velocity of the compressed air therethrough to create a vortex in the cavity to thoroughly mix the air with the fuel passing through jets 21 of the injector to provide more efficient combustion. Recesses are provided in the piston immediately below each cavity to permit the circulation of cooling oil to cool the cavity and prevent distortion of the main bearing bush.

Title: Pressure regulator system for hydraulic turbine installations
Inventor: FISCH JACOB
IPC: F03B15/04
Filed: 1960-08-05
Abstract: 887,140. Hydraulic turbines. ALLISCHALMERS MANUFACTURING CO. Aug. 5, 1960, No. 27307/60. Class 110 (3). An hydraulic turbine comprising gate means through which water is supplied to the turbine and a by-pass valve through which water is diverted upon closing of the gate means has linkage directly interconnecting the gate means and a movable valve member of the by-pass valve and pressure responsive means, connected to the valve member, operable, when the bypass valve has opened consequential upon closing of the gate means, to return the valve member gradually towards its closed position. The supply of water to the turbine is controlled by wicket gates connected to a rod 70 and the flow of water through a by-pass by a valve 36 comprising a fixed cone 38 and slidable valve sleeve 40. When the load on the turbine is suddenly released, the wicket gates are rapidly closed by a conventional governor within a few seconds. This causes the rod 70 to move to the right shifting lever 66 from position J to position I. This, in turn, moves rod 72 to the left and cause pivot 74 to move from C to D. The pivot A being momentarily stationary, the lower end of the lever 44 moves from E to F to open the valve 36. The penstock pressure entering the right-hand end of dashpot cylinder 48 through conduit 54 causes the piston 62 to move to the left, the rate of movement being determined by the size of orifice valves 61, 61<SP>1</SP>. As the piston 62 moves to the left, the lever 44 swings about point D so that the by-pass valve 36 slowly closes. When the characteristic of the discharge through the turbine and by-pass valve is non-linear, the pivot between the levers 68, 72 may be replaced by a bell-crank having a cam slot in which operates a cam roller attached to the lever 72 and a lever pivoted to a stationary support. A rod 92 attached to the piston 62, and provided with an abutment 94 cooperates with an adjustable stop member 96 to limit the amount by which the by-pass valve 36 is closed.
