Filed: 1914-09-04
Granted: 1915-10-04
Abstract: 19,446. British Thomson-Houston Co., [General Electric Co.]. Sept. 4.. Protective arrangements.-Relates to the protection of vacuum tubes or other discharge devices having unilateral conductivity, such as the hot-cathode tubes described in Specification 15,788/14, [Class 39 (i), Electric lamps, Arc &c.]. In order to guard against the effects of short circuit on a line receiving rectified current from the tubes, or on any other load-circuit in series with them, a device controlling the trip circuit of one or more automatic switches is arranged to respond to increased flow of energy through a tube. In the arrangement shown, two vacuum tubes 1, 2 have their anodes 4, 4' connected to terminals of a transformer 7 and their cathodes 3, 3<1> connected to a work-circuit 9. A battery 11 and resistance 12 are provided for heating the cathodes as described in the Specification referred to above. According to the invention, a circuit-breaker 22 adapted to open the primary circuit 23 has its trip-coil 19 excitable by the operation of an energy relay 17, which comprises a current coil 14 in series with the anode 4 and a potential coil connected across the anode 4 and the cathode 3. The relay responds when an excess-voltage arises coincidently with flow of current through the tube, but not to excess voltage without current. The tube 1 may be provided with a similar protective arrangement. Instead of opening the supply circuit, a resistance may be inserted.

Granted: 1915-11-02
Abstract: 21,880. Bradford, L. Nov. 13, 1913, [Convention date]. Surface-tension separating processes and apparatus.-A process for the preferential separation of lead sulphide or pyrites or both from zinc sulphide consists in submitting the ores to flotation in an acid medium which wets the zinc sulphide particles so that they sink while the lead sulphide or pyrites particles or both are permitted to float, such medium consisting of an acid solution to which is added a small quantity of a reducing-gas, or a solution of such gas, or a substance capable of evolving a reducing-gas, such as thiosulphates. sulphites, bisulphites, sulphides, or polysulphides; for example, the medium may be a dilute solution of sulphurous acid. A frothing-agent is used in cases in which a reducing-gas is introduced; when the reducing-gas is generated in the medium by reaction, a frothing-agent need not be used. In some cases, the ore may be digested with sulphuric acid and reducing-agent before effecting the flotation operation. When the concentrate of lead sulphide or pyrites or both has been obtained, the zinc sulphide may be floated after treatment of the medium by the addition of an oxidizing-agent, or by agitation with steam and air, or by draining the residues and resubmitting them to flotation. In the apparatus shown, the ore and solution are mixed in a vessel a communicating by a valved pipe h with a centrifugal pump g, acid being admitted from a pipe i and steam and air, if necessary, from an injector k. The outlet l of the pump has a throttle valve m, past which the pulp is delivered under pressure into a spitzkasten n wherein the separation occurs, the concentrates passing away at a shoot o, while the residues flow off continuously at ar. outlet p.
