Filed: 1931-01-22
Abstract: 371,919. Squirting. WELLMAN SEAVER ROLLING MILL CO., Ltd. and SMITH, S., Victoria Station House, Victoria Street, London. Jan. 22, 1931, No. 2200. [Class 83 (iv).] A hollow billet B1, Fig. 5, for use in a drawing operation is formed by extrusion from a solid billet by effecting relative movement between the billet and a punch and die and supporting sleeve for the billet movable with the die. A billet B, Fig. 1, of square cross section is supported on an anvil 43. A sleeve 44 rests on collars on rods attached to the head 45 of the press, and is brought into a position surrounding the billet to prevent lateral movement thereof by raising the head 45, and is retained by suitable means in this position while the head 45 is lowered. A sleeve 47 is thereby forced over the billet initially to compress and reshape it, the resistance encountered causing the punch 54 to move ahead of the sleeve 47 and die 48 through a distance determined by a surface 45a abutting the upper surface of the support 51 for the die and sleeve, to bring the die and punch-head into substantially the same plane. The head 49 is at the same time lowered to rest on the container 40, further downward movement of the head 45 causing the billet to be extruded between the die and punch, while the sleeve 44 is moved down until it occupies the dotted line position of Fig. 1. The formed billet is stripped from the punch by a bush 56 on upward movement of the head 45, a member 70 secured to the head 49 being brought into its path. The head 49 is secured to the container during the stripping operation by hooks 57 engaging projections 58. The die 48 may have a flared portion 61, and may be divided to facilitate removal. Reference has been directed by the Comptroller to Specification 16042A/06, [Class 83, Metals, Cutting &c.].

Title: Knotter
IPC: B65H69/04
Filed: 1937-01-26
Abstract: 489,434. Knot-tying devices. ABBOTT MACHINE CO. Jan. 26, 1937, No. 2297. Convention date, Feb. 12, 1936. [Class 112] In uniting two strands by a weaver's knot, a loop is formed by bending each of the two strands round the other, causing one strand end only to extend through the loop, and tightening the loop around this end. The device has a strand guide 20 with a slot 21 for the strand x and an edge 22 against which the second strand y lies. Both strands lie in the notch extending along the back of the device. The strands are crossed by a circular disc 57 having strandreceiving notches 60, 61. The disc is operated by teeth engaged by a toothed quadrant which is operated by a link having a follower tracking a cam groove 78. The strands are crossed doubly and are engaged by the loop-forming bill 26 which enters between the crossings. The pivoted cutter blade 29 is opened at this position by the cam plate acting on its extension 32 and further rotation of the bill causes the strand y to be engaged between the blade 29 and the fixed blades 27, 28. Further rotation causes the cutting of the strand y and the insertion of its end inside the knot-forming loop. A pivoted stripper arm 84 operated by a follower tracking a cam groove 88 has a hook 86 to strip the knot off bill 26 and tighten the knot by pulling the strand y from between the blades of the bill. A second rotary bill 35 rotates about the same axis as the loop-forming bill 26. The bill 35 has fixed blades 37 and 38 and a cutting and holding blade 42 with cam operated action similar to the cutter on the other bill. The bill 35 operates on the strand x. The bills are mounted in a U-shaped frame 45 and their shafts driven through gears from a shaft 54. This shaft may be operated by a solenoid 105 carrying a rack 106, Fig. 11. This arrangement is particularly useful when the knotter is used with the automatic winding machine described in British Specifications 459,357, [Group IX], and 489,435. Alternatively, the shaft may be operated as described in British Specifications 489,433 and 489,461, and U.S.A Specification 1,868,682.

Title: Process and apparatus for hydrocarbon conversion
IPC: B01J8/00
Filed: 1950-02-01
Abstract: <PICT:0677095/III/1> <PICT:0677095/III/2> In the conversion of fluid hydrocarbons in the presence of a cyclically moving granular contact material, catalytic or otherwise, which is passed downwardly through the conversion and contact material reconditioning zones, the material is elevated from the base of the reconditioner to the top of the converter and also, if the converter and reconditioner are positioned side by side, from the base of the converter to the top of the reconditioner through a gas-operated lift pipe, at least two streams of lift gas being supplied to the lower end of the lift pipe which is immersed in a bed of the contact material, one of the streams being fed directly to the bottom of the pipe without passing through any substantial thickness of the bed and the other being fed into the solid at a point spaced from the lift pipe so as to convey the solid into the first stream.  The solid material entry to the lift pipe is controlled at the desired rate by adjusting the flow of the second stream of gas.  The linear velocities of both gas streams are maintained not greatly in excess of nor greatly less than that of the mixed gases in the lift pipe.  As shown, contact material is passed as a downwardly moving bed through converter 11 and reconditioner 12. Hydrocarbon feed enters the converter at 36 or 41 and product gases leave at 64.  Regenerating gas or cooling or heating gas depending on whether the contact material is catalytic or a heat transfer medium enter the reconditioner at 81 and leave at 88. Contact material from the reconditioner is collected in tank 13 and elevated by steam through lift pipe 14 to hopper and separator 10 from which steam is withdrawn and condensed at 130 thereby creating a partial vacuum in hopper 10 and enabling the tank 13 to be operated at substantially atmospheric pressure.  Steam is supplied from line 118 to valved branches 107, 112 and 113, that from branch 107 being discharged directly into the flared lower end of lift pipe 14, Fig. 4, through a distributer 104 and that from branches 112, 113 being discharged through distributer 110, 111 to convey material from the bed 102 through annular passage 106 into the first stream.  A three-way valve 117 is designed to correct any adjustment in steam flow through branches 112, 113 by an opposite and equal adjustment in the steam flow through branch 107.  In a modification the secondary feeder steam is introduced into tank 13 above the bed 102 in which case the pressure in the tank may be above atmospheric, and a suction-type lift is not employed.  Instead of steam as a lift gas other condensible or alternatively non-condensible gases may be employed in which latter case the barometric condenser 130 is replaced by a vacuum pump.  The process is applicable to catalytic cracking, isomerization, hydrogeneration, reforming, dehydrogenative aromatization, hydroforming and desulphurization of petroleum fractions and high temperature pyrolytic conversions such as the conversion of propane and ethylene or of methane to acetylene.
