Title: Improvements in or relating to welding
IPC: C21D9/50
Filed: 1940-08-06
Abstract: 542,781. Welded joints. BUDD MANUFACTURING CO., E. G. Aug. 6, 1940, No. 12661. Convention date, Sept. 7, 1939. [Class 83 (iv)] In making an article by resistance welding from parts one of which is formed of thin sheet metal susceptible to transverse distortions as a result of shrinkage of the metal of the weld, the distortions are removed by cold working the weld metal to an extent sufficient to expand the metal permanently in the plane of the sheet an amount equal to the contraction caused by such shrinkage. The welds may comprise spaced or overlapped spot welds. In removing the shrinkage stresses from a stainless steel aircraft skin sheet 11 spot welded to a corrugated stainless steel member 13, the welded article is placed with one of the corrugations over an anvil 18 and peening is effected by an air hammer 19 provided with a gauge 20<SP>1</SP> and an air regulating valve 191. The work may be fed gradually with a timing arranged so that each peen blow overlaps the preceding blow. Spreading or upsetting of the softened metal at the welds is thus effected to obtain a total elongation to bring the length equal to the original unstressed length prior to welding. When welding softer sheet metal the peening may elongate also the metal between the welds. The invention may be applied to two overlapped seam welded sheets or to the longitudinal seam of the cylindrical wall of a stainless steel fuel tank for aircraft. In such case backing strips 24, 25. at one or both sides of the parts 26, 27 may be welded together with the parts. The flanged bottom welded in the wall of the tank may be similarly treated.

Abstract: 711,053. Electrical distributers. STANDARD TELEPHONES & CABLES, Ltd. June 1, 1951 [June 2, 1950], No. 13072/51. Class 40 (3). [Also in Group XL(c) An electronic switch comprises a plurality of pairs of rectifying cells connected in opposition, each pair being between a common terminal and one of a plurality of terminals, and means for circulating a current through one pair only, so that signals may be transmitted between the common terminal and the appropriate one of the plurality of terminals. In Fig. 3, each of terminals 25, 26, 27, 28 is connected through a separate pair of rectifiers 38, 39, connected in opposition, to a common terminal 29. The intermediate point of each pair of rectifiers is connected through a resistance to battery 37, and through further rectifiers to two of the control terminals 32, 33, 34, 35. Selected combinations of potentials are applied to control terminals 32, 33, 34, 35 two of the terminals being positive and two being negative (or earthed) in each combination. The arrangement is such that the current from battery 37 is shunted away from all the pairs of rectifiers associated with terminals 25-28 except that one which is connected through the further rectifiers to the two control terminals which are positively biased. Thus signals may be transmitted from any one of the terminals 25-28 through a low impedance circuit to terminal 29, the selection being controlled by the potential combination applied to terminals 32-35. A modification is shown in Fig. 4, in which the same result is achieved by a simpler arrangement in which either terminal 44 or 45 is connected to the current source, and positive or negative potentials are applied to terminals 32 and 33. More complicated arrangements on a similar basis are described in which one of 8, 16 or 20 terminals may be selectively connected to a common terminal, the control being affected by combinations of potentials applied to a series of control terminals. Pulse trains may be applied to the control terminals so that the common terminal is connected successively to each of the plurality of terminals.

Abstract: 1,182,582. Ornamenting. WORCESTER ROYAL PORCELAIN CO. Ltd. 20 March, 1967 [26 March, 1966], No. 13472/66. Heading B6G. A raised pattern on ceramic ware is produced by applying to a glazed or non-porous surface of the ware a collodion-supported pattern-form of colour material produced separately from the ware and on the surface of which a finishing metal or other material is carried and thereafter firing the ware to fix the finishing metal or material on to the pattern form. Alternatively a collodion-supported pattern-form of the requisite colour material is applied to a glazed or other non-porous surface of the ceramic ware, and the ware is fired to remove the supporting collodion matrix whilst leaving the pattern form exposed on the surface of the ware. The pattern-form is then treated with a moistening agent and a powder of the required finishing metal or material, e.g. gold or silver and re-fired to fix the latter on the raised pattern-form. The pattern-form may be deposited initially on a backing sheet, e.g. of paper by a screen printing process. The collodion may be brushed or sprayed over the pattern form. The backing sheet may be coated with a release medium which is soluble in or rendered fluid by the application of water so that the collodion supported pattern form can be slid or peeled off the backing sheet and laid on the ware with the pattern-form next to the ware. Silver sand may be applied to the surface of the powdered layer which is then rubbed with a polishing cloth or pad. The colour material utilized for the pattern-form may be particles of selected oxide of a size to pass through a substantially finer mesh than the mesh of the screen utilized for the screen printing process.
