Abstract: 499,280. Converting. BRITISH THOMSON-HOUSTON CO., Ltd. June 16, 1938, No. 17943. Convention date, June 16, 1937. [Class 38 (ii)] [Also in Group XL] In a converting arrangement which comprises a discharge device 4 provided with a highresistance starting electrode 8, permanently immersed in the cathode 7, the starting voltage to the electrode 8 is supplied from a condenser 15 and an inductive reactance 16 in dependence upon the degree of magnetization of the reactance which is determined by the intensity of ionization in the device. D.C. is supplied through valves 4, 5 to the mains 2 from the A.C. source 1. Each valve has exciting anodes 9 which are connected to a transformer 19, supplied from the source 1 through a phase shifter 14 and a transformer 13. The centrepoint on the transformer secondary 21 is connected through a, winding 18 on the reactance 16 to the cathode 7, so that rectified current flows therethrough ; the degree of magnetization of the reactance will therefore depend upon the current in winding 18. The winding 17 and the condenser 15 form a tuned circuit so that when the maintaining arcs to the anodes 9 are extinguished, the reactance becomes unsaturated and voltage impulses are supplied through the rectifier 22 to the electrode 8.

Abstract: 145,707. Leavitt, F. M. July 1, 1919, [Convention date]. Water-tube boilers; feed-water, supplying; pressure, regulating.-In a steam-generator applicable for use in aircraft, the feed-pump, the fuel-supply pump, and the blower supplying air to the furnace are under the simultaneous control of the operator, and the steam supply to the turbine or other engine is controlled by automatic means maintaining a uniform pressure in the generator. The feed pump E, Fig. 1, of the coiled tube flash boiler A, the fuel-supply pump F and the blower G are driven by a motor D controlled by a manually operated valve 12 in the steam supply pipe 11. The steam outlet from the boiler is contrclled by a valve mechanism comprising a lift valve 17, Fig. 2, so operated by the boiler pressure that the valve opens to allow steam to pass to the turbine when the boiler pressure rises above a predetermined point. Steam taken from the boiler through a flexible tube 24 so acts upon a piston pilot valve 20 against the pressure of a spring 22 that when the predetermined boiler pressure is reached, the pilot valve allows steam to enter a cylinder containing a piston 18 on the end of the spindle 19 of the lift valve, which is then lifted to allow boiler steam to pass through the port 9 to the turbine.

Abstract: 188,357. Davis, A. J. July 5, 1921. Buoy and like lamps; vehicle and like lamps; mounting electric lamps in lanterns.-A navigation light for aircraft comprises an electric lamp bulb enclosed within a glass dome which gives, in use, a large angle of visibility in the horizontal and vertical planes and a mask around the bulb, the edge of which mask limits both the vertical and horizontal angles of visibility to predetermined but large angles according to the function of the light and does not reflect light externally of the dome. Screwed into a socket 17, Fig. 2, on the lamp-body 16 is a glass dome 18 containing a lamp-bulb 23 carried by a tubular support 21 held in a metal seating 24 secured in position by a clamping-nut 25. The cylindrical mask 40 secured in the interior of the body 16 limits the angle of visibility in a vertical plane over an angle of 180‹ and in a horizontal plane over an angle of 220‹ for the head-lights for the aircraft, over an angle of 110‹ for the starboard and port lights, and over an angle of 140‹ for the tail-light. These various angles of visibility are obtained by specially shaping the outer edge of the masks, a hemispherical hood being hinged at one side of the mask to obtain the angle of 110‹ for the starboard and port lights. A locking-lever 32 pivoted on a clamping-screw 29 has at one end a plate 34 engaging a groove 15 in the dome 18 and is secured in position by a screw 35 mounted on a bracket support 30 and engaging a slot in the lever 32.

Title: Dehydrogenation catalysts and applications thereof
IPC: C07C45/00
Filed: 1950-07-21
Abstract: Alcohols are dehydrogenated to aldehydes and ketones in the presence of a fluidized catalyst comprising barium oxide, chromium oxide and cupric oxide on finely-divided inactive alumina (see Group III).  The reaction is effected at, e.g., 600-700 DEG  F., and, if desired, under pressure.  Steam and oxygen are preferably admixed with the alcohol vapours to prevent the occurrence of side reactions, to absorb the liberated hydrogen and to maintain activity of the catalyst.  Examples describe the dehydrogenation of isopropyl alcohol to acetone and of n-propyl alcohol to propionaldehyde.ALSO:A dehydrogenation catalyst, particularly for use in the conversion of alcohols to aldehydes and ketones (see Group IV(b)) employing the fluidized technique, comprises barium oxide, chromium oxide and cupric oxide on finely-divided inactive alumina and is prepared by slurrying the alumina particles in aqueous barium acetate, cupric nitrate and chromic nitrate, evaporating to dryness with stirring and heating the coated particles in air, if desired employing the fluidized technique and a temperature of 600-700 DEG F. to decompose the salts to oxides.  The catalyst may be regenerated with air at 650 DEG F. employing the fluidized technique and may be kept active during the dehydrogenation reaction by mixing air or oxygen with the reactant vapours.
