Title: Improvements in or relating to the manufacture of dispenser cathodes
IPC: H01J9/04
Filed: 1957-07-19
Abstract: 817,066. Cathode materials and processing. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 19, 1957 [July 24, 1956], No. 22936/57. Class 39(1). In a method of making impregnated dispenser cathodes, the porous cathode body to be treated is embedded in freshly alkaliearth oxide and then heated rapidly, for example to about 2000C., in an inert atmosphere such as a mixture of hydrogen and nitrogen or a rare gas at a pressure of at least one half an atmosphere so that the oxide melts and impregnates the cathode body. In a modified method, the porous body is embedded in an alkali earth compound or mixture of such compounds such as the carbonates, peroxides, hydroxides or nitrates which decompose into oxide before a significant amount of the original material impregnates the body. Particular care is taken rapidly to transverse the temperature range at which the oxy-carbonate phase exists. The impregnating materials used are BaO alone or mixed with other alkali earth oxides, with carbonates preferably used as starting materials in the modified method described above, a preferred mixture being BaCO 3  and SrCO 3  in proportions lying between 1 : 2 and 5 : 1. In all cases it is preferred that the final BaO content should be at least 25 per cent. The cathode body to be impregnated consists of pure tungsten, a tungsten-molybdenum alloy or a tantalum-molybdenum alloy. In the case of tungsten cathodes the density of the body is between 55 per cent. and 90 per cent. of that of the solid metal and the sintering temperature is preferably above 2100C. After cooling the cathode body, the adhering layer of oxide is removed and the cathode is mounted in an evacuated electron tube and activated by heating for some time at 1250C. Impregnation times vary from 15 seconds to 10 minutes. The life times of various cathodes are given.

Title: Production of telomers
IPC: C07C17/275
Filed: 1954-08-10
Abstract: In the preparation of telomers of polymerizable unsaturated aliphatic hydrocarbons, e.g. ethylene and propylene, with chlorinated aliphatic hydrocarbons, e.g. chloroform, dichloromethane, methyl chloride, hexachloroethane and trichloroethane under pressure, using a free-radical producing catalyst, the reaction is caused to proceed at a controlled rate by using chlorinated aliphatic hydrocarbons which have been saturated with a gas containing free oxygen, e.g. air, and in which a proportion of the oxygen absorbed has been displaced by an oxygen-free gas, e.g. ethylene.  The molecular weight distribution in the product may be controlled by regulating the temperature. In an example, ethylene under pressure and containing benzoyl peroxide is reacted with carbontetrachloride which has been saturated with air and partially replaced by ethylene.

Abstract: 444,788. R÷ntgenray apparatus. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Aug. 19, 1935, No. 23278. Convention date, Oct. 19, 1934. [Class 39 (i)] [See also Group XX] A projecting anode tube 14 on a R÷ntgen-ray tube suitable for examining narrow, hollow work-pieces carries the target 16 at its free end and also carries coils 17 or other focusing devices, and means such as a rheostat 18 enables regulation of the focusing effect and so the size of the focal spot on the target 16. The coils 17 may be adjustable, or the tube 14 flexible, and moved to move the focal spot over the target 16. The coils 17 and tube 14 may both be flexible, or the tube 14 may be curved, for introduction into curved work-pieces. X-rays emerge transversely through a thin part of the side wall of the tube 14 ; rays not emerging transversely are intercepted by a slotted screen moved with the tube relatively to the work-piece. The coils 17 may be replaced by electrodes forming focusing lenses. The X-ray tube is mounted by a ball-joint in the wall of a metal casing with the tube 14 projecting and adjustable in position. The casing contains a Villard supply circuit including a condenser and rectifier. To regulate the focusing, individual focusing members may be switched off or reversed. The focusing may be varied with the potential applied to the X-ray tube, as by coupling together mechanically or electrically the devices for regulating the focusing and the tube potential or by feeding the focusing devices from the primary or secondary of the transformer supplying the tube. When the tube is fed with pulsating current, the electrons may be concentrated only when the potential is above a certain value to reduce heating of the target by the generation of soft X-rays at lower potentials ; the focusing devices are then controlled by a synchronous switch or fed from the tube potential through a choking coil with a saturated core, and shutters are arranged inside the tube 14 to intercept cathode rays not proceeding to the focal spot. These shutters and the target end of the tube 14 may be cooled. The tube current may be varied with the focusing by coupling a regulator for the cathode heating current with the focusing regulator.
