Title: Automatic electric arc welding
IPC: B23K9/028
Filed: 1957-05-13
Abstract: 849,836. Welding by fusion. BATEMAN, W. H. June 16, 1958 [May 13, 1957; Dec. 13, 1957]. Nos. 15085/57 and 38741/57. Class 83 (4). In an arc welding machine a device engaging a template provides relative movement between the torch and the work, causes the torch to follow the line of the seam being welded and maintains the torch at a constant angle to the seam. An automatic arc length control is superimposed on the movement of the torch derived from the template. In a machine for welding a contoured longitudinal seam on a workpiece 10, Fig. 1, the template is in the form of a strip 20 secured to members 19 on the frame 15 of the machine. A carriage 17 on horizontal rails 14 supports a slide 23 vertically movable between rollers 36, Figs. 2 and 3. The slide 23 carries a roller 27 engaging the upper surface of the strip 20 and a motor 24 geared to the roller 27. In operation, the roller 27 drives the carriage 17 along the rails 14 and vertically moves the slide 23 to maintain the torch 18 at the correct distance from the seam. Spring- loaded rollers 29 journalled in a housing 28 engage the lower surface of the strip 20 and when a curved portion is reached the rollers 29 turn the housing 28 about the axis of the driving roller 27 to actuate gears 32, a telescopic shaft 34 and gears 45 to rotate a pivoted sector 38 carrying the torch 18 to maintain the torch 18 normal to the seam. The torch is movable towards or away from the sector 38 which is mounted on an auxiliary slide 35 guided vertically by rollers 36 on the slide 23 and adjustable relative to the slide 23 by a threaded rod 37 driven by a reversible motor 37a controlled according to variations of the arc voltage to keep the arc length constant. The slides 23, 35 may be counter balanced. The welding torch has a gas-shielded non-consumable electrode to which filler wire is fed by rollers 51 driven by the motor 24. Spring arms 50 support the welding cable and gas tubes. In a modification for making circumferential welds the carriage 17 is dispensed with, and the work is rotated about a fixed axis by a drive derived from the rotation of the template by the driving roller, the rollers engaging the template controlling the positioning of the torch as described above. A non- consumable electrode without filler wire or a consumable electrode may be used.

Title: Preparation of zinc and cadmium sulphides
Inventor: JACKSON PETER ARTHUR
IPC: C01G11/00
Filed: 1963-04-17
Abstract: Zinc and cadmium sulphides are prepared by purifying a solution of zinc and cadmium chlorides, particularly from Fe, Co, Ni, Mn and Cu, by the use of anion-exchange resins in chloride form, and then precipitating ZnS and CdS from the purified solution by adding ethyldithiocarbamate, thioacetamide or thiourea. The chloride solution is passed down a column of the resin and Mn, Fe, Co and Ni and most of the Cu are eluted with HCl.  The remaining Cu is eluted with demineralized water, followed by the Zn and Cd as chlorides. The purified chloride solutions may be converted to the acetate, nitrate or sulphate form by being passed down columns of anion exchange resin of the appropriate form.  A preliminary separation of Zn from Cd may be effected before the main purification stage by passing a solution of ZnSO4, 7H2O and 3CdSO4.8H2O down a column of ion-exchange resin in iodide form, the Zn passing through and being removed completely by elution with an aqueous solution of KI and K2SO4.  The Cd is then eluted, with NH4OH, as Cd(NH3)4I2.  The Zn and Cd effluents are then passed separately through columns of ion exchange resin in chloride form to yield solutions of ZnCl2 and Cd(NH3)4Cl2 respectively, which are then purified by the main process.

Title: Process for the manufacture of ethylene dichloride and other olefin dihalides
Inventor: LANDAU RALPH
IPC: C07C17/02
Filed: 1953-05-30
Abstract: Ethylene dichloride and other olefin dihalides are manufactured by a method comprising reacting with halogen under superatmospheric pressure a gaseous mixture containing 0.5 to 5 per cent of olefine by volume but constituted predominantly by inert gases together possibly with other gases which are non-reactant with halogen under these conditions and other hydrocarbons.  A source of ethylene, for example, may comprise a commercial gas such as refinery waste gas or producer gas, a tail gas from a hydrocarbon catalytic cracking operation or the residual ethylene component found in the tail gases purged from ethylene oxidation systems.  When chlorine is used as the halogen it may be introduced into the reaction zone at several points. Preferably the reaction is carried out in the absence of light. The usual chlorinating catalysts may be used if desired.  The reaction is accelerated if it is carried out in the presence of iron, preferably in the form of iron reaction vessels or containers.  To prevent the formation of trichlorethane when dichlorethane is being prepared a small amount of trichlorethane may be added initially.  In the example tail gas containing 2 per cent by volume of ethylene along with ethane, carbon dioxide, oxygen, nitrogen and water is passed through an iron reaction tube at 150 pounds gauge and chlorine is passed into the tube through a series of nozzles; a mixture containing ethylene dichloride is obtained; the gaseous mixture is scrubbed with a lime slurry and then passed through an activated carbon bed which absorbs any chlor-substituted compounds. Alternatively the gases may be passed direct through the carbon bed.
