Abstract: 714,689. Thermal switches. CARRON CO., and PHILIP, A. R. May 2, 1952 [April 30, 1951], No. 10035/51. Class 38(5) [Also in Group XI] Steam from the spout or lid of a kettle supported on a cooker impinges on a metal casing 24 of a thermostatic switch in series with an immersion heater in the kettle so as to control current supply to the kettle. A bimetallic strip 20 is supported at one end by an insulating block 19 on a bent metal arm 16 pivoted or hinged at 15 on a plate 14 on a terminal block 11. A current supply lead 18 is connected to an adjustable contact pin 17 on the block 11 and current passes through the arm 16 of the thermal switch which is connected by a wire 10 to be in series with the immersion heater of the kettle. The centre of gravity of the arm 16 is such that the lower, end of the arm normally contacts the contact 17. The free end of the bimetallic strip 20 rests against an adjustable pin 21, so that on impingement of steam on the heat-conductive casing 24 of the thermostat the strip bends to break the contacts 17. The current-conveying bar 16 carries a magnetizing block 23 adjacent but not in contact with a permanent magnet 22 on the support 11. A pilot lamp in parallel with a resistance may be in series with the kettle and thermostatic switch. A press button may be arranged to short-circuit the thermostat.

Title: Improvements in or relating to the Process of Burning Solid Fuel.
Inventor: THUMAN FREDERIC
IPC: C10J3/00
Filed: 1918-06-20
Abstract: 120,011. Thuman, F., (Evans, O. B.). June 20, 1918. Processes of combustion of solid fuel.-Solid fuel is burned in furnaces or gas-producers in a manner which prevents the adherence of clinker to tha side walls of the fire-space. Fig. 1 shows a furnace wherein the combustion in the zone is such as to fuse the ash in the fuel, which passes then into a zone 6 at the top of which the ash solidifies. The unconsumed fuel prevents the ash from forming into large masses of clinker, and to prevent the solidifying clinker from adhering to the side walls, the fuel is separated from them by a space a. This may be effected, for example, by an inset bosh 7, beneath which the temperature necessary to keep the clinker solid is maintained and regulated by air and steam, or cooling-agents, combustion products, &c., supplied by connexions 9, 11 respectively. The combustion is completed on the grate 3 by air and steam, &c., supplied by connexions 8, 10. In a modification, the bosh 7 is hollow, and the connexion 11 supplies air &c. through it to the space a.. A water-gas producer, Fig. 3, may be worked similarly, air being initially admitted through connexions 14, 15, and combustion products taken off by a connexion 22, and steam, combustion products, &c., admitted by valves 16, 17, when necessary. In gas-making, the valves 14, 15 are closed, steam is admitted by the valves 16 or 17, or both, and gas is withdrawn by the off -take 22. Alternatively, the flow of gases through the fire may be reversed; the valves 16, 17, 19 are closed, steam is admitted through the valve 18, and the gas is taken off by the valves 20 or 21 and the offtake 22. The valve 20 enables the temperature in, and positions of, the zones 5, 6 to be controlled. In a modification, the air, which may be mixed with products of combustion, steam, &c., is delivered, alternatively into the lower or upper parts of the fuel bed, by centrallysituated pipes, by means of which the temperatures in, and positions of, the zones 5, 6 may be controlled.
