Abstract: 653,109. Electric welding. WILLIAMS & WATSON, Ltd., and WILSON, L. B. July 6, 1948, Nos. 18082/48 and 7281/49. [Classes 83 (ii) and 83 (iv)] Making window-frames.-In electric welding aluminium and its alloys in a resistance welding machine, the workpieces are flashed, brought and held in contact until the adjoining ends melt to break the circuit, and joined and consolidated by mechanical pressure with the current switched off. In a modified method an additional stage after flashing comprises compressing the parts together and then breaking the joint, with the current off. One workpiece 16, e.g. part of a window frame is held against a fixed current carrying jaw 14 and the other part 17 is similarly held against a jaw 15 mounted on a platform 13 moved by an edge cam 35 driven from an electric motor 38 through an electromagnet or solenoid-operated clutch 31. The cam-shaft 36 carries further cams 44, 45, 27 operating a clutch switch 42, a clutch relay switch 30 and a main supply, e.g. 400 v. 50 cycle, switch 26. A voltage relay 28 is connected across the jaws 14, 15. In operation with the work clamped and the motor 38 running a press button 43 supplies the clutch 31 to start the cam-shaft 36, when cam 44 closes switch 42 to replace the button control. The cam 35 then feeds the work during flashing through 200 degrees of rotation after cam 27 closes switch 26 operating contactor 25 to energize the blocks 14, 15. Cam 44 opens switch 42 to de-energize clutch 31 and movement of cam 35 stops. A rise on the main cam 35 then holds the workpieces together until the interface melts and breaks the main circuit. The relay 28 is thus energized and with switch 30 closed by cam 45, re-engages the clutch 31 to restart the feed while cam 27 opens switch 26 to operate contactor 25 and switch off the main current. Joining and consolidation take place over 60 degrees of rotation of cam 35 and cam 45 opens switch 30 to stop the machine for resetting by the button 43.

Title: Improvements in or relating to the manufacture of cellulose from lignin-containing cellulosic materials
IPC: D21C3/16
Filed: 1936-07-03
Abstract: A process for the manufacture of cellulose comprises subjecting lignin-containing cellulosic materials such as wood, straw, grass or wood pulp to a simultaneous treatment with a lower fatty acid and with nitrous acid in the liquid phase, followed by treatment with alkali.  The lower fatty acid may be concentrated or an aqueous solution of 15--75 per cent concentration.  The nitrous acid is preferably formed from a nitrite by the fatty acid or by a mineral acid not greatly in excess of the theoretical quantity in the presence of the materials being treated.  The nitrite is preferably employed in aqueous solution in an amount equal to \ba1/4\be--5 per cent of the fatty acid.  The weight of acid liquor is preferably at least 10 times that of the cellulosic material.  The treatment may be in the cold or at elevated temperature, e.g. 50 or 100 DEG  C. Pressure may be atmospheric or higher produced, e.g. by an inert gas. The alkali treatment may be with cold alkali of 10--20 per cent and/or with hot alkali of 5 per cent or less, if desired under pressure.  The acid treatment may be preceded by an alkaline one, e.g. with 1--5 per cent caustic alkali at 100 DEG  C.  The material may be treated with dilute p  alkali or with water to remove resins, gums and like material, and if desired some lignin may be preliminarily removed by means of sulphite liquor.  The treatments may be carried out in stages separated by washing or alkaline treatments.  The material may be bleached with chlorine or hypochlorite.  For the manufacture of organic esters of cellulose the material may be treated with a mineral acid, or more particularly a lower fatty acid in liquid or vapour form.  The esterification catalyst may be introduced during pre-treatment.  Mineral acid used in pretreatment may be neutralized or substantially neutralized before esterifying. British Specifications 263,938, 312,098, [both in Class 2 (ii)], and French Specification 565,654 are referred to.  The Provisional Specification describes a process for extraction of cellulose from lignin-containing cellulosic material by treatment with nitrous acid in liquid phase.
