Title: Method and apparatus for making welded tubes
IPC: B23K37/053
Filed: 1960-04-06
Abstract: 900,201. Making tubes; welding by fusion. HAZEN, F. DE F. April 6, 1960, No. 12128/60. Classes 83 (2) and 83 (4). In making welded seam tubing, a preformed sheet metal tube blank is held with its edges abutted under external pressure, the pressure being applied uniformly over the edges and over the full length of the tube blank, and the edges are arc welded and maintained under pressure until the weld is cooled. A sheared stainless steel sheet is preformed between dies to form a tube blank for a furnace recuperator and this blank is placed between dies 1, 2, the die 2 being secured to the frame 3 and die 1 secured to a beam 22 having cups 19 loosely receiving' the heads 18 of hydraulic pistons 17. The pistons are then actuated to bring the edges of the blank together in parallel relation, a bottom electrode 34, Fig. 8, being carried on a holder 39 spaced from a similar member by an inflatable rubber hose 40. The edges are welded by an arc welding electrode 33 and the pressure on the tube is maintained until the fused metal has cooled so that the tube does not distort or the joint open. The pressure on the edges may be 6.6 tons per square inch.

Title: Improvements in machines for and processes of making and filling bags
IPC: B65B9/20
Filed: 1921-04-28
Abstract: 182,972. Bates, A. M. April 28, 1921. Paper bags, sacks, and the like, making.- Relates to a process and apparatus for making and filling bags. A strip of bag-making material is fed from a roll D through printing rolls E to a former F, the edges being united by a sewing machine G to form a tube. The tube is turned inside out by being fed down the interior of the former F, and a feeding tube K extends downwards inside the tube. A quantity of the tube R is disposed in a puckered condition to provide a reserve from which it is drawn off, beneath an elastic band S and over expanding means R<1>, for filling. The end of the tube having been closed by the preceding operation, a charge of material is dropped from the feeding tube K into the freely swinging portion Q of the bag tube. The apparatus may be arranged so that the weight of the charge effects a downward feed of the bag tube, or it may be fed by other means. A tube-sewing and severing apparatus N isthen moved across the bag tube, needles P forming seams, and devices O severing the material between the seams. Alternatively the bag tube may be moved relatively to the apparatus N. The bottom of the tube is thus left closed for the next operation. When paper is used to form the bag pasting means are substituted for the sewing means.

Title: Process for producing lubricating oils
Inventor: BLANDING FORREST HARVEY
IPC: C10G21/00
Filed: 1953-05-04
Abstract: High viscoscity index petroleum lubricating oil is produced by catalytically cracking a gas oil boiling between 650 and 1100 DEG F., fractionating from the products a fraction boiling between 700 and 1100 DEG F., removing aromatic constituents therefrom and recovering the remainder as petroleum lubricating oil.  The catalytic cracking may be carried out at 800-1000 DEG F. and at a pressure from atmospheric to 25 p.s.i.g.  The catalyst may be a natural or synthetic clay or a gel, e.g. montmorillonite clays, silica-alumina and silica-magnesia; fixed or moving beds or fluidized or suspensoid systems may be used.  Aromatic constituents may be removed by solvent extraction, e.g. by countercurrent contacting with SO2, phenol, which may contain water as a solvent modifier, furfural or nitrobenzene, or by contact with an adsorbent such as silica gel.  Before or after removal of aromatic constituents the oil may be dewaxed, preferably by solvent dewaxing, e.g. with propane or methyl ethyl ketone.

Title: Improvements in the electrolysis of magnesium chloride
IPC: C25C3/04
Filed: 1943-08-06
Abstract: 569,783. Electrolytic production of magnesium and chlorine. MATHIESON ALKALI WORKS. Aug. 6, 1943, No. 12765. Convention date, Aug. 6, 1942. [Class 41] [Also in Group III] In a process for electrolyzing fused magnesium chloride, in which the make-up chloride salt is fed to the charge in the hydrous form, production of magnesium hydroxy chloride due to the dehydration of the hydrous salt at the high temperatures prevailing, is suppressed by feeding strong hydrochloric acid into the charge along with the hydrous salt, such acid being derived from the anodic gas mixture of the electrolysis and being separated from the chlorine in that mixture, the chlorine being recovered. The make-up salt is introduced at chute 15 into the fusion in the feed-chamber 4 of the cell, the fusion passing 'thence, preferably through a superheating chamber 5, into the electrolysis chamber 3 wherein the magnesium is segregated by webs 13. Any gases formed by the introduction of the salt into the fusion are taken off at 16, so largely diminishing production of. hydroxy chloride, whereas the chlorine and hydrogen chloride are drawn off at 14 and passed to an absorber 18 where they are separated by scrubbing by a constant boiling mixture of 19% HC1 to remove the hydrochloric acid, the chlorine being discharged at 20. The hydrochloric acid, discharged at 21, is regenerated in a still 22 for re-use in the absorber 18, any surplus being discharged at 23. Hydrochloric acid concentrated by vaporization from the boiling mixture in the still 22 is returned to the feed-chamber 4 through connections 24, 26, to suppress decomposition of the hydrous salt. By the process, the amount of hydrochloric acid separated from the anodic gas mixture is proportioned to the amount of hydroxy chloride formed by dehydration of the salt, and 50-80% of pure chlorine is recoverable from the total chlorine supplied to the fusion. Figures of temperature of the cell and voltage employed are given.

Abstract: 581,221. Welding. WRIGHT, J. A., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. July 6, 1944, No. 12900. [Class 83 (iv)] An intermittent seam spot-welding machine, comprising a pair of welding rollers 5, 6, of which 5 is driven intermittently, so as to feed the work during the off periods of the welding circuit, by a motor-driven adjustable-throw crank 13 or eccentric driving through a connecting rod 12 an intermittently oscillated arm 11 rotating the rollers step-by-step by a ratchet and pawl device 9, 10, is provided with a normally closed edge distance switch 24, which is opened, preferably by a cam 20 on the eccentric shaft 14a, at a predetermined point of each rotation of the eccentric, and which has in series therewith normally closed auxiliary contacts R2a of a main. relay R2 and the operating coil R3 of another relay, the energization of which is adapted to close auxiliary contacts R3, Fig. 4, in the circuit of the motor 19, the contacts R2a being opened by energization of the main coil R2 arranged in series with contacts 25 closed by a stop-andstart switch, the energization of the coil R2 also closing the main contacts R2, Fig. 4, to energize the motor in parallel with which contacts are the contacts R3. When using fluid pressure, the contacts 25 constitute a pressure switch. At the start of a seam, the rollers are brought together by a compressed-air cylinder associated with which is the pressure switch 25, the contacts of which close when a predetermined pressure is applied to the work, the closing of such switch energizing the coil R2 to close contacts R2, Fig. 4, to start up the motor and so the sequence of operations. During each welding operation the energizing circuit containing the switch 24 is open at R2a and so will not affect the operation of the motor. When the seam is completely welded, the pressure switch 25 opens to open contacts R2, Fig. 4, but contacts R2a close to energize coil R3 and'so close the contacts R3, Fig. 4, :so that the :motor continues to rotate until the cam 20 opens the edge distance switch 24. Thus, the eccentric is automatically set in proper position to give the predetermined distance 4 from the edge of the work of the first spot weld on a new piece of work. This distance may be changed by unlocking the cam and rotating it by hand and then relocking on the shaft. According to the Provisional Specification the apparatus maybe used for welding - aluminium or alloys thereof and the welding current may be initiated by contacts operated by a cam on the eccentric shaft.
