Title: Improvements in method of welding aluminium
IPC: B23K35/38
Filed: 1949-07-18
Abstract: 659,015. Uniting by fusion. AIR REDUCTION CO., Inc. July 18, 1949, No. 18873. Convention date, July 28, 1948. [Class 83 (iv)] A method of welding aluminium and aluminium alloys comprises feeding an aluminium or aluminium alloy wire 5 to a point adjacent and spaced from the workpiece 18, maintaining an electric arc between the wire and the workpiece and surrounding the arc with an inert gas. The wire 5 is withdrawn from a reel 6 by rolls 9 driven by a motor 10 and passes through a current pick-up shoe 11 in an electrode holder 12 which has a gas chamber 13 and a nozzle 14 for discharging the gas around the wire electrode 5. The pick-up shoe 11 and the workpiece 18 are connected by cables 15 and 17 to a welding machine 16. A cylinder 19 delivers the gas, preferably argon, through a valve 20 to a pressure gauge 24 then to a pressure-reducing valve 21 and via a pressure gauge 25 to a pipe 22 controlled by a valve 23 leading to the chamber 13. The delivery rate of the gas must ensure a laminar flow and that the arc atmosphere contains not more than 2 per cent by volume of impurities and not over ¢ per cent of atmospheric impurities. The workpiece is used as the cathode so that the oxide film on the work is removed by electron emission and positive ion bombardment at the weld puddle. The current may range from 75 to 1050 amperes at 14 to 30 volts. Aluminium or aluminium alloy plates above three-eighths of an inch in thickness can be welded in a single pass at high speeds with 480 amperes D.C. reverse polarity at sixteen inches per minute with no edge preparation _ other than sawing. Preheating for heavy sections is reduced from 400‹ to 150‹ F. or lower. Helium and the inert atmospheric gases of greater atomic weight than argon, or mixtures thereof, may be used. The wire 5 is preferably uncoated but may have a wash coating of any suitable material to aid the stabilization of the arc.

Abstract: 444,727. Rolling plated sheets. DEUTSCHE ROHRENWERKE AKT.-GES., 69, Breitestrasse, Dusseldorf, Germany. July 3, 1935, No. 18964. Convention date, July 3, 1934. [Classes 83 (ii) and 83 (iv)] In plating iron or steel sheets with a covering of copper or similar metal by rolling, spreading of the copper is prevented by first rolling the composite pack at a lower peripheral speed (30-40 per cent lower) than normal rolling speed for iron &c. only, and with less than normal cross-section reduction (i.e. at 8-12 per cent reduction) and then re-rolling at the same reduced peripheral speed, but with 14¢-16 per cent reduction of cross-section. Ordinary rolling is then continued if necessary after removal of the usual protecting plates. Specification 444,728 is referred to.

The filmforming material may be cellulose acetate, formate, butyrate, butyrate-acetate or nitrate, ethyl or benzyl cellulose, polyvinyl chloride or acetal, a polyacrylic or polymethacrylic ester or polystyrene and may contain plasticizers, dyes or pigments. The Specification, as open to inspection under Sect. 91, comprises also the use of metal or fabric strips or iron or copper wires and methods of making the tubes as by dipping, dry extrusion, blowing, a combination of dipping or dry extrusion with blowing to enlarge the tube formed by the first step, and butt welding or spiral wrapping of film or foil with or without dipping. This subject-matter does not appear in the Specification as accepted.
Patent GB-359479-A (GB)
Title: A process of coating metallic surfaces for prevention of corrosion
IPC: B05D7/18
Filed: 1930-06-23
Abstract: Metal surfaces are protected against corrosion by first applying a coating containing a high proportion of lime mixed with a binder, and treating with a colloidal solution of silica obtained by the hydrolysis of an alcohol solution of a silicon ester, whereby an insoluble lime silicate is formed.  A final coating of cellulose lacquer, varnish or enamel may be applied. The primary coating composition may consist of Portland or hydraulic cement, or lime, a binder such as glue, gelatin, casein, egg albumen, blood serum, or algin or other vegetable proteins, a filler such as alkaline earth, magnesite, asbestine or pigments together with a little resorcin as preservative.  The mixture is ground with water, or a mineral, animal, or vegetable oil to form a paste which is applied by brush or by spraying.  The coating when dry is then treated with a colloidal solution of silica containing formalin, and preferably a little linseed oil.  The process may be applied to ship's tanks which are to contain oils, molasses or salt water.

Patent GB-220943-A (GB)
Filed: 1924-08-16
Abstract: 220,943. Brauer, E. Aug. 24, 1923. [Convention date]. Condensers.-In variable plate condensers the metal and dielectric coatings are solidly united to form elastic plates. The dielectric layer on each plate may consist of a coating of varnish covered with pulverized mica or other insulating material, or it may consist of sheets of mica paper, silk or the like glued to the metal plate. The dielectric layer may consist of several spaced plates or strips to ensure its extensibility. In one construction, Fig. 4, the condenser comprises a cover-plate 3 of sheet bronze and two elastic plates 1, 2 of the same metal, the lower surfaces of the plates 1 and 3 being covered with dielectric. A spindle 6 passes through the plates and is formed with a screwed end 7 engaging a nut 8 secured to the plate 2. On rotating the spindle the plates are caused to approach or recede from one another, the distances between adjacent plates being kept substantially equal by providing insulating abutments 59 at the ends of the plate 1. In a modification, Fig. 6, five metal plates 16 - - 20 are provided, the middle plate 18 being plane, while the outer plates are curved in opposite directions. The plate 18 is covered with dielectric on both sides, and the plates 17, 19 have dielectric layers on their outer surfaces. The edges of the plates are held between insulating blocks 25, 26 and the capacity is adjusted by rotating a screw 29 which engages a nut 30 secured to the plate 16. Guide members in the form of tubes or rods of glass or the like may be passed through the plates. In a modification, the outer plates are made shorter and of greater curvature than the inner plates, the outer insulating blocks being correspondingly increased in length. Means may be provided for switching out some of the plates in order to give a lower minimum capacity.

Title: A process for the production of caustic potash and oxalic acid
IPC: C01D1/20
Filed: 1933-07-10
Abstract: Caustic potash is obtained from potassium sulphate by first treating with alkaline earth formate, or components yielding the same, so as to produce potassium formate, heating the latter to convert it into oxalate, and acting on the potassium oxalate with alkaline earth hydroxide to give caustic potash solution, which may be concentrated.ALSO:Potassium sulphate is converted into formate by the action of an alkaline earth formate or components yielding the same, followed by conversion of the formate into oxalate by heating at temperatures of 300--450 DEG  C., and preferably under reduced pressure.  This product is then treated with alkaline earth hydroxide to give caustic potash lye and alkaline earth oxalate, the former of which is separated off and concentrated if desired, while the latter is treated with mineral acids to convert into oxalic acid.  An example is given in which calcium is used as the alkaline earth and the calcium oxalate obtained is worked up with sulphuric acid.
