Title: Improvements in butt welding
IPC: B23K5/02
Filed: 1941-07-15
Abstract: 552,416. Welding plates, pipes, rails &c. LINDE AIR PRODUCTS CO. July 15, 1941, No. 8923. Convention date, Feb. 4. [Class 83 (iv)] In pressure butt welding of plates, pipes, bars, beams, rails &c. an end of each of the parts is provided with an unbevelled portion and at least one bevelled portion, the unbevelled portions are forced together while heating the metal at and adjacent the abutting portions to a temperature approximately equal to the solidus temperature of the metal to upset the heated metal in the region of the groove and weld the parts together and heat and pressure are discontinued when the free surface of the upset metal is approximately level with the main surface of the parts. Heating is within the range between 1050‹ C. and 1300‹ C. and is effected by oxy-fuel torches preferably applied to the parts adjacent the interface after pressing the parts together or may be effected by electric-resistance. Both parts may be bevelled at both sides 15, 15<SP>1</SP> or at one side only, the thickness of the interface 13 being preferably about half the thickness of the parts in the case of a double bevel and three-quarters in the case of a single bevel. The angle of bevel may vary between 60 degrees and 75 degrees. The pressure which may be from 300 to 600 lbs. per sq. inch may be varied during operation so as to maintain a constant unit pressure throughout. The joint may be annealed at 900‹ C. After welding, the exposed metal adjacent the interface may be fuzed to remove oxide impurities if the upset metal extends more than 1/16 inch above the surface of the members. The occlusion of oxides may be prevented by spacing the bevelled portions from each other by shoulders 50, Fig. 5, so as to increase the initial rate of outward flow of upset metal. The thickness of the shoulders may be at least half the thickness of the parts for a double bevel or three-quarters for a single bevel. Plates may be heated by a pair of water cooled multiple tip torches 17, 19 which may be reciprocated across the joint during heating. Joints in pipes may be heated by inner and outer torches 31, 39 which may be reciprocated across the joint the torches or work being also oscillated in the plane of the joint. Rails may be bevelled at a, d and each side at b, c, Fig. 9.

Title: Improved manufacture of starch paste
IPC: C09J103/02
Filed: 1921-03-23
Abstract: An adhesive consists of starch paste containing a small quantity of soap which is added to the starch before or during its conversion into paste.  The soap must be soluble in or emulsifiable with water, such as a soap of a resin acid or fatty acid such as stearic acid, palmitic acid, oleic acid, wood-oil acid, ricinoleic acid, erucic acid, brassic acid, fish oil acids, colophonic acids, cerotic acid, melissic acid, &c.  The soaps obtained by saponification of oils, fats, waxes such as bees-wax and vegetable wax, spermaceti, or wool fat may be used, and also the anilides or their homologues.  The soaps may contain the non-saponifiable constituents of the fats, oils, waxes, or wool fat.  Soaps of potash, soda, ammonium, calcium, and other metals may be used.  In an example 1 kilo of starch is mixed with 50 grams of ground soap and boiled with 5 litres of water. The soap may also be mixed with the starch and passed with water over roller driers.  The flakes thus produced are ground and mixed with water to form an adhesive.  Another method consists in saponifying fats, oils, waxes, &c. with an alcoholic solution of alkali in the presence of starch, or acids may be mixed with the starch and saponified with bases or carbonates.  Specification 4719/08 is referred to.

Title: An improved process for the purification of naphthalene
IPC: C07C7/148
Filed: 1950-04-12
Abstract: Crude naphthalene is purified by a process which comprises treating at elevated temperature the crude liquid naphthalene with a small proportion of isobutene gas, tertiary butyl alcohol or di-isobutene in the presence of an acid catalyst whereby the isobutene, tertiary butyl alcohol or di-isobutene combines with the impurities without reacting with the naphthalene and separating the unchanged naphthalene from the products of the reaction.  Acid catalysts mentioned are phosphoric acid and concentrated sulphuric.  The naphthalene may be finally washed with water and dilute caustic soda solution.  In examples: A C4 refinery gas containing isobutene is passed through crude, heated, liquid naphthalene in the presence of concentrated sulphuric acid (I) and (III) and a mixture of crude naphthalene, tertiary butyl alcohol and sulphuric acid is heated under reflux (II).  The naphthalene is recovered by sublimation in each example and in example (I) the product is compared with the products obtained by purifying crude naphthalene by sublimation and washing with concentrated sulphuric acid, water and caustic soda.
