Abstract: 397,940. Protective arrangements. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.- (Assignees of Christensen, H. ; 434, West 120th Street, and Knoop, W. A. ; 36, South St. Paul Road, Hempstead, both in New York, U.S.A.) March 7, 1932, No. 6878. Convention date, March 19, 1931. [Class 38 (iv).] The peak voltage across an alternating- current circuit is limited by means of one or, preferably a pair of hot cathode gas-filled discharge devices having characteristics such that when the applied voltage tends to exceed a critical value, the voltage across the device remains constant. Two or three electrode tubes may be used. As shown, Fig. 3, the voltage drop in a resistance 27 carrying the heater current is used to provide the normal anode voltage. The two halves of the primary winding of transformer 15 are tightly coupled. The reserve tubes 18, 19 having characteristics which need differ only very slightly from those of the other pair are normally inoperative but come into operation singly or together on failure of either or both of the normally used tubes. Additional cold electrode discharge tubes 39, 40 are connected to the cable to guard against failure of both the hot-cathode pairs and discharge of these tubes produces a noise in a loud-speaker 36. In a modification, Fig. 7, the control electrodes and the anodes are connected together. An adjustable biassing voltage is provided by the resistance 27 and is different for the two pairs of tubes owing to the effect of a further resistance 13 in the heating circuit. When the reserve tubes come into action a relay 30 rings a bell. Signal lamps 40 glow when the corresponding heater fails. A ballast resistance 28 is included in the heater circuit. Specifications 339,270, [Class 40 (v), Wireless signalling &c.], and 379,707, [Group XXXIX], are referred to.

Abstract: 115,428. British Westinghouse Electric & Manufacturing Co., (Assignees of Ehrhart, R. N). May 4, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Condenser systems.-Steam condensing plant comprising a condenser 5 fitted with a steam jet air ejector 7 and a condensate pump 6 both discharging to a chamber 10 in which the condensate is heated and the steam is simultaneously condensed, is provided with automatic means for supplying supplementary liquid to the chamber 10 when the supply of condensate is not sufficient to condense the steam. The supplementary supply is obtained by opening a valve 16 and thus allowing water to flow from the hot-well 9 to the upper part of the condenser 5, whence, after it has been cooled by passage over the condenser tubes, it is forced by the condensate pump 6 to the chamber 10. To control the valve 16, a float tank 13 is provided. Water flows from the chamber 10 to the tank 13, and thence through an adjustable valve 14 to the hot-well 9. If the supply of condensate fails, the tank 13 empties and a float 18 opens the valve 16. In a modification, the valve 16 is controlled in accordance with the pressure of the steam in the turbine or other engine, the steam pressure operating upon a spring-backed piston by which the valve is opened when the engine is not working.

Filed: 1938-03-07
Abstract: 531,543. Destructive hydrogenation. JOHNSON, G. W. (I.G. Farbenindustrie Akt.-Ges.). March 7, 1938, No. 7110. [Class 32] In the production of liquid hydrocarbons, e.g. benzines and middle oils by the catalytic destructive hydrogenation of carbonaceous materials, e.g. coals, tars, mineral oils &c. gaseous olefines are added to the reacting materials before or during the reaction. The gaseous olefines are produced by cracking ethane, propane or butane or are obtained from the waste gases of cracking or hydrogenation processes and are led into the preheater or reaction vessel in the latter case, particularly when di-olefines are present, after a considerable amount of the reaction has taken place, e.g. at positions situated after the first quarter or third of the reaction zone. The hydrogenation may be carried out in the presence of small amounts of hydrogen so that only a limited hydrogenation takes place. A layer of catalyst promoting alkylization or polymerization may be arranged at the points where the olefines are introduced. The amount of olefines introduced may be 10-200 per cent. by weight of the initial material treated. A gas, comprising 23 per cent. by volume of propane, 22 per cent. butane, 21 per cent. ethylene, 13 per cent. propylene, 6 per cent. butylene, and 15 per cent. hydrogen which has been produced by cracking waste gases from a catalytic hydrogenation process, is mixed with mineral coal pasted with oil and 3 per cent. ferric oxide purifying mass pre-treated with hydrogen sulphide, and the mixture is passed under 300 atmos. pressure through a pre-heater heated to 410‹C. into a reaction chamber where additional hydrogen is added and the materials are maintained at 410‹C. for one to two hours. The yield of benzines, middle oil and heavy oil is increased by about 35 per cent. by the addition of the olefines.
