Filed: 1941-04-24
Abstract: 548,970. Heat treating tubular members. BUDD INDUCTION HEATING, Inc. April 24, 1941, No. 5321. Convention date, May 17, 1940. [Class 72] In the heat treatment of a tubular member, heat, e.g. by electromagnetic induction is applied to an annular internal zone of the member while effecting relative movement in an axial direction between the member and the heating means, and after the applied heat has flowed to the external surface of the member quenching fluid such as oil or gases, e.g. air is applied to the external surface. Quenching fluid may be applied subsequently to the inner surface. The tube 10 is moved downwardly past an induction heater 12 and the heated tube is quenched by liquid under pressure from a nozzle 32 supplied from a chamber 28 fed by a pipe 34 and mounted on a rod 46, the nozzle being directed away from the heater 12. To assist the downward flow of the quenching liquid, gas or air under pressure is fed by a pipe 38 into a chamber 36 formed by a shield 24 and thence down between the chamber 28 and the tube 10. An internal quenching device 22 provided with annular conical jets 40, 42 is adjustably mounted upon a support 44 and fed with liquid from the pipe 41 passing through the support 18 for the heater 12. The heater and the quenching device may also be rotated. Flame heaters may be used instead of the induction heater 12. Specification 509,895, is referred to.

Title: Improvements in the production of yarns containing staple fibre from continuous filaments
IPC: D01G1/10
Filed: 1936-02-22
Abstract: 470,794. Yarns. BRITISH CELANESE, Ltd., TAYLOR, W. I., and WOODRUFF, A. H. Feb. 22, 1936, No. 5389. [Classes 120 (ii) and 120 (iii)] Yarns containing staple fibre are formed from a bundle of continuous filaments by drawing the bundle between a cutting surface and another surface which presses it against the cutting surface and utilizing the pull of the bundle of continuous filaments to drive the cutting surface in the same direction as, but at a lower speed than, the bundle ; the driving of the cutting surface by the bundle may be assisted by a non- positive drive and the drive may be retarded, according to the denier of the yarn being operated upon. As shown, the cutting surface is formed by a roller 3 having sharp-edged flutes 5 and the bundle 25 is pressed thereon by a roller 8 provided with flutes 9, and rotating in slotted bearings 6 ; the roller 8 may be raised from the roller 3 by a lever 10 pivoted in the frame 1 and held against either of two stops 14, 15 by a spring 12. The roller 3 is braked bv a spring 18 pressed against a surface 17 on the roller by a screw 20 passing through a lug 22 on the frame. The roller 8 is formed with cavities 36 in which weights may be inserted to vary its pressure against the roller 3. The bundle containing the staple fibre passes from the roller 3 to a guide 24 and between rollers 26, 27, 28 to a device 33 bv which it is twisted and wound on to the package 34 ; the roller 28 is driven and drives the rollers 26, 27 which are disposed in slots in a bracket 29, the slots for the roller 27 being inclined so that as the roller is dropped into its slots it carries the yarn over the roller 28, behind the roller 27 and in front of the roller 26. When yarns of fine denier are being made, the movement of the cutting roller may be assisted by an air jet directed against vanes secured to the roller. The device may be applied to winding, twisting, doubling, warping or knitting machines. Specifications 424,830, and 424,879 are referred to.
Patent GB-833705-A (GB)
Title: Destructive hydrogenation of asphaltic hydrocarbons
IPC: C10G45/00
Filed: 1957-02-18
Abstract: Asphaltic hydrocarbons are converted into hydrocarbon oils of lower boiling range by mixing the asphaltic hydrocarbon with a virgin gas oil, boiling in the range of 550-1050 DEG  F. with at least 85 volume per cent boiling above 650 DEG  F. and containing at least 20 volume per cent of naphthalenes and at least 30 volume per cent aromatics, so that the mixture contains not less than 0.5 part of gas oil per part of asphaltic hydrocarbon, and passing the mixture together with hydrogen (500 to 6000 cubic feet per barrel of mixture) over a desulphurization catalyst, such as cobalt molybdate, at a temperature of 725-825 DEG  F., a pressure of 100-2000 p.s.i.g., and a space velocity of 0.25 to 5.0 volumes of mixture per volume of catalyst per hour.  In an example, a residual fraction obtained by the distillation of West Texas crude oil is mixed with virgin gas oil in the volume ratio of 1 : 3; and the mixture is passed with hydrogen (2910 SCF/Bbl.) over a fixed bed of catalyst comprising cobalt molybdate supported on silica-free gamma alumina.  The temperature in the reactor is 782 DEG  F., the pressure is 800 p.s.i.g., and the space velocity is 0.5.  The total liquid products contained about 40% less naphtha-insolubles than the residual fraction feedstock.  When the catalyst loses its activity, it is reconditioned by cutting out the asphaltic component of the feed mixture, and charging only the virgin gas oil and hydrogen to the catalyst bed at reaction temperatures.  After repeated reconditioning, however, it may become necessary to subject the catalyst to regeneration with oxygen-containing gas to burn off carbonaceous deposits.
