Abstract: 667,171. Heat - transmitting media. BROWN, S. J., and WAIGHT, J. F. Dec. 3, 1949 [Nov. 6, 1948], No. 28871/48. Class 64(ii) In apparatus for controlling the temperature of a furnace or other chamber, e.g. a retort, kiln, muffle or oven, which operates at a temperature above 1500‹F. a heat transferring fluid such as oil, water or a gas flows continuously through a member 12 subjected either to the heat in the furnace or to the heat radiated by a workpiece and then flows over a thermal element 15 mounted externally of the furnace and controlling the fuel or power supply to the furnace or to the succeeding furnace of a series of furnaces. The thermal element operates at a temperature not exceeding 800‹F. and may be a thermocouple, thermopile or bimetal. As shown, the heat-transmitting fluid is circulated by a pump 11 through a conduit loop 12, e.g. of steel, copper or brass, in the furnace and.after passing over the thermal element returns by way of a cooler 16 to a reservoir in which the fluid is preheated and kept at a controlled temperature. A switch 25 operated by the thermal element 15 controls solenoid-operated relay valves 22, 23 which regulate the supplies of air and gas respectively to a burner 19. In a modified arrangement, a thermosiphonic circulation is set up by a raised reservoir with a long communication for natural cooling, to a heat-receiving member which forms part of the furnace wall. The device may be applied to furnaces arranged for series flow of workpieces so that one or more of the furnaces are controlled by the temperature of the preceding furnace or of the workpiece emerged therefrom. If air is used as the heat-transmitting fluid, after passing over the thermal element it may discharge to atmosphere or be used as preheated air for the gas burners. Specifications 633,698 and 636,953 are referred to.

Title: Hydraulic system with cooling flow circuit
IPC: F15B21/0423
Filed: 1973-06-18
Abstract: 1389386 Hydraulic control circuits BORG-WARNER CORP 18 June 1973 [13 July 1972] 28887/73 Heading F1P In the circuit shown in Fig.1, with a control valve 30 as shown, fluid is cooled when it passes from a variable displacement pump 10 through a restriction 50, conduit 47, valve 30 and conduit 44 to a sump 11. Output fluid in excess of this limited flow causes pressure to build up in conduits 41, 45 and in a displacement decreasing cylinder 24, so that the pump output decreases to a minimum. At the same time the pressure in a displacement increasing cylinder 23 and in conduit 46 is reduced. When the valve 30 is moved to its other position, a rotor 12 is operated and the conduit 47 is closed preventing any cooling flow to the sump: Fig.2, (not shown), illustrates a similar arrangement in which the restriction 50 is replaced by a relief valve and the motor has a minimum displacement stop. In Fig.3, when a control valve 30 is in the neutral position shown, flow through a line 41 is blocked and pressure fluid acts on a land 69 of a sensor valve spool 61 to move it to the right against a spring 75. This connects ports, 65, 66 and pressure acts on a displacement decreasing cylinder 24 through conduits 81, and 82. Some cooling fluid passes through a central bore 72 in the spool 61, out of port 68 and through conduit 83 to the sump via control valve 30. When the control valve is moved to operate the motor 12, fluid-pressure acts on a land 71 to move the spool 61 to the left thereby connecting the displacement decreasing cylinder 24 to the sump. The flow of cooling liquid is interrupted because port 32 is not connected to the sump.

Abstract: 1,057,435. Lighters. LA NATIONALS S.A., and RONSON CORPORATION. July 23, 1963 [July 27. 1962], No. 29076/63. Heading F4F. A gas-fuelled cigarette lighter provided with a fuel burner, a fuel shut-off valve and a fuel throttling device for determining the flame height has a single manual control lever 17 operating both the shut-off valve and throttling device. The lever 17 has a forked end 20 engaging a groove in the top of a plunger 10, forming the burner, which is slidably mounted in an element 9 slidable in the fuel burner body 6. The bottom end of the plunger 10 has an insert seating against a gas aperture in the bottom of element 9 to form a gas shut-off valve. The bottom of element 9 has an annular rim adapted to compress a wick 7 against a ball 8 on the bottom of the burner body 6 to form a throttling device. The top edge of element 9 is engaged by the edges of an aperture 15 in a lever 14 pivoted on lugs 13 on the body 6 and actuated by a cam surface 16 on the lever 17. The top end of the plunger 10 passes through the aperture 15. When the manual control lever 17 is depressed against a coil spring 19 the plunger 10 is lifted to enable gas to flow through the bore in the top thereof and the cam surface 16 depresses the element 9 via lever 14, thus compressing the wick 7 to reduce the flow of gas to the burner. In a modification, Figs. 3, 4 (not shown), the shut-off valve and throttling device are formed by a tapered screw 25 in a screw-threaded upper part 24 of a gasfeed tube 22. The tapered screw 25 has a square shank 26 engaged by burner 27 fast with a manual control lever 28 pivoted about the top end of tube 22. The lever 28 is sprung to project externally of the lighter in the inoperative position. A flint 32 with a spring 33 are held in a groove 31 by a sheet metal cover 36 holding a flint wheel 34. The operator's thumb rotates the flint wheel and then turns the lever 28 to increase the clearance between tube 22 and the screw 25 enabling gas to reach the burner 27. When released, the lever 28 turns to hermetically seal the gas tube 22. In Figs. 5 and 6 (not shown), two arrangements of the above screw 25 and screw thread 24 are shown. In one arrangement the thread 24 is of trapezoidal section with truncated apexes and the screw has a cylindrical outer surface and the troughs of the threads on a conical surface. In the other arrangement the screw 25 is normal with truncated thread apexes and the thread in the tube 22 has the thread apexes on a cylindrical surface and the troughs of the thread on a conical surface. The levers of both embodiments may also rotate the flint-wheel.
