Title: Improvements in or relating to cold pressure welding
IPC: B23K20/02
Filed: 1956-05-08
Abstract: 793,402. Welding by pressure. GENERAL ELECTRIC CO., Ltd. May 8, 1956 [May 10, 1955], No. 14310/56. Class 83 (4). In cold pressure welding a butt-joint between two coaxial tubes of similar cross-section, the tubes are both supported internally and externally and are held accurately in alignment during welding. The tubes 24, 25, Fig. 2, are supported on inner dies 14, 15 mounted on a guide bar 20, and are clamped by split external dies 12, 13 having conical outer surfaces engaging in conical apertures in carriages 16, 17. Movement of the carriages 16, 17 together exerts clamping pressure on the external dies 12, 13 and welds the tubes until the dies contact each other. During welding the metal of the projecting ends of the tubes is forced sideways into recesses 22, 23 in the dies. In a modification, Fig. 5, the carriages 36, 37 carrying the dies are guided by a pin-andsleeve 38, 39. The inner dies 42, 43 are supported in the external dies 31, 32 which have projecting cylindrical portions 33, 34 which during welding slidingly fit within a fixed guide ring 35. The carriages may be power or hand actuated. When welding tubes of differing now characteristics such as two aluminium tubes of different hardness or a copper and an aluminium tube, the harder tube 50, Fig. 8, is formed with a grooved end, and the softer tube 51 with a rounded end to equalize the amount of metal which each supplies to the weld. Specifications 689,927 and 728,139 are referred to.

The harder portions of the tool may consist of a plate 1, Fig. 1, of a conglomerated iron foundry powder having another hard substance such as a carbide or oxide. The softer portions consist of cylindrical studs 2, 3, 4 arranged in runs and made of conglomerated copper powder and the same synthetic resin as that used for the harder portions. The studs are made by introducing a mixture of copper powder and resin into a mould, the mixture being hardened cold or with heat and pressure.

Title: Improvements in or relating to the prevention of corrosion of metals in contact with oxygen-containing water
IPC: C23F11/08
Filed: 1957-05-14
Abstract: 884,932. Preventing corrosion. ELLIS, S. R. M. Aug. 13, 1958 [May 14, 1957], No. 15202/57. Class 123(1). Corrosion of steam boilers and the like by water containing dissolved oxygen is inhibited by adding to the water hydrazine or a salt or derivative thereof in an amount considerably less. than the amount equivalent to the oxygen present, for example in an amount from 10-60% of that stoichiometrically necessary, under conditions such that the reaction between the oxygen and hydrazine is slow. The hydrazine is employed, for example, as hydrazine hydrate or as a salt such as hydrazine phosphate, sulphate or oxalate. A double salt such as sodium hydrazine phosphate or compounds of hydrazine with tannic acid, tannino or organic sulphonic acid dispersing agents may be used. The addition is made to water at relatively low temperature whereby the hydrazine-dissolved oxygen reaction rate is slowed. Stabilisers for the hydrazine such as morpholine, cyclohexylamine, ethylenediamine, sodium -sulphite or thiocyanate, thiourea or formaldehyde may be added to slow the reaction further. The invention is of especial use in static conditions, for example in boilers which have been closed down.
