Title: An Improved Process for the Manufacture of Combustible Gas
Inventor: BOWING JOHN
Filed: 1903-12-28
Granted: 1904-11-03
Abstract: 28,498. Bowing, J. Dec. 28. Gas-producers.-In the manufacture of water gas, the carbonaceous charge in the generator is heated by means of highly-superheated steam to avoid the admixture of atmospheric nitrogen with the gas as in the ordinary process of making water gas. The steam, which may be superheated to a temperature of say 700‹ C., is admitted under considerable pressure through a perforated pipe p into the comminuted charge contained in a producer a. The producer is provided with charging-openings c and an exit pipe q, and the bottom b may be removable. The steam may be heated in coil or regenerative superheaters, such as d, d', which contain honeycomb or other bricks. The bricks are heated by furnace gases or by combustion of gas within the chambers. In the latter case, gas is admitted by pipes f, f<1> the waste gases passing off through pipes h, h<1>, while steam is admitted by a pipe l and passes out by a pipe n. The heating of the bricks and the passige of the steam are made to take place in each superheater alternately, by suitable opening and closing of the gas and steam valves. The valves must be so constructed as to withstand the high temperature.

Title: Improvements in and relating to Vapour Burning Apparatus.
Inventor: SMITH HARPER FORREST
Filed: 1904-05-03
Granted: 1904-06-30
Abstract: 10,167. Smith, H. F. May 3. Valves for automatic liquid supply; actuating and cleaning valves.-In incandescent vapour lamps and burners, the supply of oil from the reservoir 1 to the vaporizer by the tube 15 is controlled by a valve 8, which is normally held open by a spring 33. Should the vapour be generated too rapidly, the increased pressure of the vapour traversing the tube 42, the chamber 31, and the tube 40 to the burners, raises the diaphragm 26 and compresses the spring 33, whereupon the oil supply is cut off by the closing of the valve 8. If the pressure still continues to rise, the further upward movement of the diaphragm 26 closes the attached valve 38 and cuts off the supply of vapour to the burners. Sediment or other impurities may be removed by unscrewing a plug.

Abstract: 8026. British Thomson-Houston Co., [General Electric Co.]. April 14. Dynamos, regulating ; motors, controlling.-For starting up three-phase motors or generators which are run up to speed as motors, successivelyincreasing voltages are employed. A double-throw switch connects the threephase mains to a portion or the whole of the winding of a threephase autotransformer, and a similar double-throw switch at each machine is adapted to connect the machine either to a portion of the transformer winding or to the mains direct. The motors or generators A<1>, A<2> are supplied with current from the bus-bars B, to which also are connected, through a doublethrow switch S, the windings of a three-phase transformer, so that the whole or a portion of each winding may be connected to the bus-bars. Each motor or generator A', A<2> is connected through a double-pole switch S', S' to either the mains direct or to a portion of each winding of the transformer. In starting up the motor A', the switches S, S' are thrown downwards, whereby a voltage, dependent upon the ratio of the portion of the transformer across the motor to the entire winding, is impressed upon the motors. The switch S is then thrown upwards, connecting fewer primary turns to the bus-bars and so increasing the voltage applied to the motors. The third and final voltage is obtained by throwing the switch S' upwards, which connects the machine directly to the bus-bars.
