Title: Improvements in and relating to welding
IPC: B23K5/24
Filed: 1932-07-09
Abstract: 401,055. Uniting by fusion. LINDE AIR PRODUCTS CO., 30, East 42nd Street, New York, U.S.A.-(Assignees of Wall, M. J., 301, Bergin Avenue, Jersey City, New Jersey, U.S.A.) July 9, 1932, No. 19451. Convention date, July 22, 1931. [Class 83 (iv).] In hand, semi-automatic, or full automatic seam-welding apparatus in which the source of heat such as a blowpipe and means for directing a welding-rod to the zone of the heat are connected together so as to maintain them in predetermined relationship, the apparatus is provided with means so as to enable it to be adjusted about a pivot situated on the side of the rod directing means remote from the source of heat. The flame and rod are in the vertical plane of the weld or symmetrically disposed with respect thereto, the flame being inclined rearwardly and applied to the work ahead of the rod and also to the end of the rod, the rod and flame converging at the welding point. One, two or three parallel or converging rods of circular, oval, rectangular, hexagonal or diamond section may be used. The feed rod R may be fed by gravity through a tube G, with contracted ends, which is secured by an adjustable ear 14 and bolt 15 to an ear 16 on a collar 17 adjustably secured to the blowpipe T. The blowpipe has a welding nozzle 13 and also a nozzle 24 for preheating the rod to bright cherry-red heat. To a collar 20 adjustably fixed on the blowpipe is secured a bar 19 having a cross arm 22 from which extend a pair of runners 23 resting on the pipe parallel to the seam and on opposite sides thereof. When welding a circumferential seam in pipes the pipes are preferably rotated, the welding apparatus being stationary. The runners act as a fulcrum for the apparatus which may be rocked thereon by a handle 10 so as to move on the rod in the upward direction so as to melt the rod faster and thus chill the puddle, if too long due to melting too quickly, since the melted rod is at a lower temperature than the superheated puddle, and in a downward direction if the work is not fused as rapidly as the rod. The apparatus may be moved back and forth along the seam during welding. The welding flame preferably contains sufficient excess acetylene to carbonize the surfaces about “ to ¢ an inch ahead of the puddle so that the parts melt superficially at a lower temperature than that of the base metal. The parts are first tack welded and the rod then lowered slightly so as to preheat it. When the parts are melted the rod is lowered into the puddle where it is melted together with the work by the nozzle 13 When a tack is reached the rod R is raised so that the tack may be preheated. In a modification the rod may be fed by gravity through tubular guides 30, 31, secured to a hand-held blowpipe having converging preheating nozzles 32 and similar welding nozzles 33.

Title: Catalytic conversion of hydrocarbons
IPC: B01J23/96
Filed: 1955-07-06
Abstract: Hydrocarbon conversion reactions are carried out in the presence of a catalyst consisting essentially of a mechanical mixture of particles of (a) a component containing platinum deposited on an inert porous support and (b) an acidic component having a catalytic cracking activity (see Group III).  Petroleum fractions boiling in the range 60-450 DEG  F. may be reformed at 700-1000 DEG  F. under a hydrogen pressure of 100-1000 lbs. per square inch gauge.  Tests are described in which (a) n-hexane is isomerized to iso-hexane at 370 DEG  C.; (b) methyl-cyclopentane is aromatized to benzene at 510 DEG  C.; (c) n-hexane at 448 DEG  C. yields isohexane and benzene; (d) cetane is hydrocracked at 700 DEG  F., yielding products boiling in the gasoline range.ALSO:A catalyst suitable for use in hydrocarbon conversion reactions consists essentially of a mechanical mixture of particles of (a) a component containing platinum, e.g. 0.1-2 per cent by weight, deposited on an inert porous support; and (b) an acidic component having a catalytic cracking activity.  Suitable inert supports for the platinum are silica gel, alumina gel, natural clays, bauxite, pumice stone, kaolin, charcoal, kieselguhr, porous glass, magnesia, asbestos, coke and magnesium sulphate.  The acid cracking component may be silica-alumina, silica-magnesia, silica-zorconia, silica-thoria, silica-beryllia, silica-titania, silica-alumina - magnesia, silica - alumina - zorconia, silica - alumina - thoria, silica - alumina - titania, silica - alumina - beryllia, halogenated silicon or alumina, or aluminium halides. If the particles of the catalyst components differ in size, they may be separated after use by sieving, flotation, or air blowing, the cracking component being regenerated with an oxygen-containing gas at 1000-1400 DEG  F. for 10 minutes to 1 hour, and the platinum-containing component with hydrogen at 900-1100 DEG  F. for 1-5 hours, the two components being recombined and used again. Alternatively, when the platinum component is supported on a carbonaceous base, this component may be burnt in air, platinum dissolved from the ash by treatment with aqua regia, and the acid solution used to impregnate the carbonaceous carrier, which is thereafter reduced in hydrogen.  Halogenated alumina, when used as the cracking component, may be regenerated by treatment with halogen, halogen acid, or a halide salt.  The catalyst are especially suitable for reforming naphthas, gasoline, or kerosene (see Group IV (b) and for hydrocracking gas oils.  Hydrocracking may take place at 500-750 DEG  F. under a hydrogen pressure of 100-5000 lb. per sq. inch gauge.

IPC: B02B1/02
Filed: 1946-07-01
Abstract: 629,600. Separating solid materials. ATELIERS DE CONSTRUCTIONS L.M.S. SOC. ANON., and PERMENTIER, F. R. DE. July 1, 1946, No. 19646. Convention date, May 13. [Class 117] A selecting device for separating grains of different forms or sizes, e.g. grains of different types in mixtures of cereals, is constituted by an endless flexible rubber band 2 provided with cells 9 of equal size which is supported and moved by two drums, 3, 4, so as to cause a portion of the flexible band 2 to travel in a vertical or nearly vertical direction, the products to be treated coming into contact along the entire width of the vertically ascending portion. As shown the vertically ascending portion 2a of the band 2 constitutes one side of a narrow funnel-like member 6 down which the grain 5 descends in a state of turbulence produced by deflectors in the walls of the funnel. The descent of the grain may be automatically regulated by a blade 8 pivoted at 10 against which the grain bears and operates through rod 11 and lever 12 to regulate the size of aperture 13 for the discharge of the larger grain. The selected grain is carried upwards and discharged over the drum 3. Funnel 6 may be provided with one or more inclined plates 6a which cause the grain to move towards the the band 2a. In a modification the vertically moving band constitutes the flank of a trough of an archimedian screw, grains being conveyed horizontally. In other embodiments the grain is conveyed by gravity or horizontally by an archimedian screw in the space between two similar bands rotating in opposite directions. and several separators may be employed in cascade so that the output of one is fed to the next. In another embodiment the flexible band separator is combined with a cyclone and.fan to separate dust from the substances. The cells may be impressed into the rubber band during the mouldings of the latter, or cells formed in strips of rubber may be fitted to the flexible band. The Specification as open to inspection under Sect. 91 describes also an arrangement in which the band provided with cells forms the external surface of a single rotatable horizontal drum against which is located an archimedian screw conveyer for conveying the grain across the width of the band the height of the screw with respect to the axis of the drum being adjustable to enable the working part of the band to occupy the desired position of inclination. It also states that the cells may be formed in strips of metal which are secured to a flexible band. This subject-matter does not appear in the Specification as accepted.

IPC: A61F2/06
Filed: 1956-06-26
Abstract: 811,661. Washing-machines. PFENNINGSBERG G.m.b.H., P. June 26, 1956, No. 19776/56. Class 138 (2). [Also in Group XXXVII] A washing-machine is driven by a pole-change motor having two sets of windings Ms, Mw, the machine being started by closing main switch HS and turning knob i to the right. Contacts L2 are thereby closed and change-over switch L1 is operated to engage contact K2. A relay S3 is energized to open the water-inlet valves, and a pilot motor ML is started. When the maximum water-level in the machine has been reached, a switch W operates to energize relay S2 so that contacts S2b are moved to stop the admission of water and to by-pass the switch W. The motor winding Mw and heater H are energized for the washing-operation of the machine, the direction of rotation being continuously reversed by means of switch R<SP>11</SP> which has contacts R1 . . . R4 and is driven by the pilot motor. After a period, the cam-operated switch L1 is actuated to de-energize the relay S2 so that the motor winding Mw and heater H are disconnected. This is followed by the actuation of relay S1 to energize the motor-winding Ms for centrifuging operation, the pilot motor ML now being energized through contact S1b and lead R<SP>1</SP>. Repeated operations of the change-over switch L1 afford alternate washing and centrifuging periods for the machine until the contact L2 opens for terminating the washing cycle.
