Title: Improvements in or relating to thermionic valve circuits
IPC: H04B1/04
Filed: 1930-04-03
Abstract: 350,630. Valve circuits. GRAMOPHONE CO., Ltd., Hayes, Middlesex, and TEDHAM, W. F., 267, Woolwich Road, Abbey Wood, London. April 3, 1930, No. 10626. [Class 40 (v).] A valve generator has its filament and plate current initially supplied from a directcurrent source, the filament being subsequently switched over to an alternating-current source preferably constituted by the valve itself. As shown, the filament 2, or the cathode heater, is connected through switch 3 and resistance 6 to D.C. mains 7, 8. When fully energized, the valve generates alternating current in the transformer 10, which is connected to the terminal 5 of the switch 3. By throwing the switch 3 this A.C. may be used to energize the filament or heater. The switch may be operated by a relay in the plate circuit of the valve ; and, in addition to an "off " contact 11, the switch may be provided with other contacts for completing the plate circuit. The A.C. generated by the valve may be used to energize a radio receiver of the kind designed to operate on A.C. mains.

April 30, 1919. vulcanized bituminous compositions.-Water, petroleum, and sulphur are added to bitumen, or bituminous compositions, and the mass is submitted to sufficient heat to dehydrate it and evaporate the added petroleum, with the simultaneous injection of chlorine. Several modifications are described. Bitumen or pitch is heated to above 212‹ F., 10-15 per cent of water is added, and about 10 per cent by volume of petroleum premixed with 10 per cent by weight of the bitumen &c. of sulphur is added to the mass during ebullition. The mass is agitated and heated under suction to evaporate the water and petroleum, and as much chlorine is simultaneously injected as will combine with the sulphur, (about 33 per cent of the sulphur). In a modification, sulphur is heated with bitumen, petroleum is added, and the mass is mixed with a moist vegetable or mineral aggregate. This is heated and agitated, and chlorine is injected as before. Tn a further modification, chlorine is passed over heated sulphur to form sulphur chloride, which is mixed with petroleum and water, added to bitumen, and the mass is heated to dehydrate it and volatilize the petroleum.
