Abstract: 237,270. Schwarzkopf, P., and Deutsche Gl³hfadenfabrik R. Kurtz und Dr. Ing. P. Schwarzkopf Ges. July 16, 1924, [Convention date]. Vacuum tubes.-Cathodes for thermionic valves of the dull-emitter type are formed of molybdenum containing uranium or its compounds, or containing uranium or thorium or their compounds together with other substances that increase their electrical resistance, for example the oxides of magnesium, calcium, strontium, and barium, by processes that do not involve a final heat treatment for activating the cathode. Compounds which produce uranium oxide when heated are added to molybdenum trioxide in quantities up to 10 per cent of uranium, forming a paste, which is dried, annealed, and reduced in hydrogen. The reduced mixture is formed into filaments by sintering or mechanical working. The oxides of calcium &c. may be added to the mixture of molybdenum and uranium or thorium compounds after it is dried and annealed. Calcium or barium molybdate may be used in place of the oxides, and these salts may be purecipitated by adding the chlorides to the nitric acid used for precipitating molybdic acid from an alkaline molybdate solution. The proportion of metallic uranium or thorium in the cathodes may be increased by adding metallic magnesium to the initial mixture, whereby some of the oxide of uranium or thorium is reduced, the magnesium oxide formed remaining in the sintered body. Specification 234,435 is referred to.

Title: Improvements in or relating to the catalytic purification or polymerisation of cracked hydrocarbon vapors
IPC: C10G50/00
Filed: 1933-06-28
Abstract: <PICT:0421650/III/1> Cracked hydrocarbon vapours after removal of fixed and incondensible gases are refined and polymerized by contact with a single catalytic mass maintained at 400--700 DEG  F.  The vapours are separated from the gases by condensation and are revaporized before contact with the refining catalyst, a stabilizing step being preferably introduced before the refining operation.  The gases separated are purified and used for regeneration of the catalyst.  Crude oil from a tank 146 is preheated in heat-exchangers 48, 16 and cracked in a conventional pipe still and reaction chamber 8, 13.  The cracked vapours pass through a heat-exchanger 40 to a fractionating tower 44 from which heavy residues are removed to a tank 52.  The vapours are condensed in a cooler 56 and separated from gases in a separator 60.  The condensate is collected in a tank 64 and passed to a stabilizer 218 of known type from which gases are removed through a line 219 and mixed in a line 203 with the gases from the separator 60 which have been scrubbed in an absorber 202. Condensate from the latter is stripped in a heater 206 and the vapours produced, condensed and separated from gases in a vessel 211, the condensate being passed to the stabilizer 218 while the gases are mixed with the other gases in the line 203.  The stabilized product is passed through heat-exchangers 110,82 into a pipe still 86 and thence into the purifiers 94, 96 filled with a contact agent comprising 98 per cent activated clay and 2 per cent finely divided nickel oxide.  The refined vapours are passed through lines 98, 100 and the heat-exchanger 82 to a column 106 with condenser, separator and collector 118, 122, 128 and the final product is received in a tank 138.  The gases collected in the line 203 are purified after passage through a heat-exchanger 224 and a heater 225 in a battery of purifying chambers 226, 227 containing finely divided metals or metallic oxides supported on carriers of the type described in Specifications 304,654, [Class 1 (i)], and 309,585, [Class 55 (ii)]. The purified gases are returned to the line 233 through the heat-exchanger 224 and may be used for regenerating the contact agents in the chambers 226, 227, 94, 96 to which they are passed through lines 178, 180, 236 and 237.  Specification 416,025 also is referred to.

Abstract: 769,575. Securing injectors in coal seams &c. FERON, J. June 24, 1954 [June 26, 1953] No. 18492/54. Class 99(1) In a device for injecting a liquid into a coal seam &c. 2 comprising a resilient sleeve 14 which is expanded radially to secure the device in a hole 1 by applying liquid pressure to a piston 7 working in a cylinder 12 whereby pressure is applied to the ends of the sleeve, a conduit 16a for the supply of liquid is formed integral with the cylinder so as to avoid the use of a separate supply pipe and damage to the sleeve caused by exerting a pull on such a pipe. The conduit 16a may consist of a bore formed in the body of the cylinder which may have handles for its manipulation; in a modification, the conduit is in one of the handles which also carries a cock for controlling flow of the liquid. The sleeve is held between plates 6, 10, the former being secured to a nozzle tube 3 fixed to the piston 7 and the latter to a tube 9 fixed to the cylinder 12; part of the tube 9 forms a bearing for the tube 3. The piston has slots 20a to receive a resilient sealing ring 20, and a similar ring 13 in a cylinder cover bears against the tube 3, both rings being under pressure from the liquid. Projections 7a on the piston limit the movement of the piston. Specification 675,501 is referred to.

Title: Improvements in or relating to methods of, and apparatus for, manufacturing synthetic jewels
IPC: C30B11/10
Filed: 1947-07-14
Abstract: 633,118. Gems. GENERAL ELECTRIC CO., Ltd., and DAUNCEY, L. A. July 14, 1947, No. 18673. [Class 43] [Also in Group XXXV] A synthetic gem boule or rod, e.g. of corundum or spinel, is formed by progressive crystallization of molten constituent material on a surface, means being provided to move the surface away from the heat source automatically in accordance with the growth of the boule or rod. Synthetic corundum is made from alumina powder which is carried from a vibrated hopper 6 by a flow of oxygen to an oxyhydrogen burner 3 in a furnace chamber comprising a hollow cylinder 2 of glass or other transparent material. Molten alumina accumulates on the top of a ceramic rod 11, which projects into the furnace chamber and is movable downwardly by a rack and pinion drive from an electric motor 16 controlled by a photo-electric cell on which is focused an image of the molten material. The ceramic rod 11 moves slowly out of the furnace, the molten alumina progressively crystallizing to form a boule or rod. The ceramic rod 11 should move a little too quickly, so that the incandescent material moves out of focus and the photo-electrical cell stops the motor by relay means 22, the rod 1 remaining stationary until the molten alumina has built up sufficiently to switch on the motor again. If the rod moved too slowly the luminous mass would rise out of focus and would continue to do so since the motor would not then become energized. Since the voltage to operate the relay 22 is greater than that required to hold it, small reductions in the intensity of light falling on the cell would not affect the relay when operating. The circuit is therefore periodically interrupted long enough to release the relay so that it will re-operate only if the voltage is sufficient. The same result may be achieved by periodically interrupting the light path. As an alternative to starting and stopping the motor, the photo-electric cell output may control the speed of the motor which will run continuously. Various diameters of rod or boule may be grown by varying the normal position of the top of the molten material with respect to the burner, this being effected by adjusting the focus of the optical system accordingly.
