Title: Improvements in or relating to welding
IPC: B23K11/00
Filed: 1932-03-30
Abstract: 404,253. Welding aircraft &c. structures. BUDD MANUFACTURING CO., E. G., 2500, Hunting Park Avenue, Philadelphia, U.S.A.-(Assignees of Ragsdale, E. J. W.; Curren Terrace, Norristown, Pennsylvania, U.S.A.) March 30, 1932, No. 9175. Void [Abridged as open to inspection under Sect. 91 of the Acts, April 1, 1932]. [Classes 83 (ii) and 83 (iv).] Metal articles, such as steel building structures, particularly stainless steel aircraft structures, subject to the corrosive effect of the atmosphere, are resistance welded by a current of much greater density than is normally used in spot welding but for a minute period of time, e.g. not greater than <1>/25 of a second, so as to avoid deleterious effects in the metal in and adjacent the weld. It is stated that the properties of the metal in the welds and in the zones adjacent thereto are substantially the same as those of the metal remote from the welds and that the spot welds are substantially smaller than spot welds in ordinary carbon steel and are of equal quality and strength and of double conical form. The steel may be austenitic and non-magnetic, such as a steel containing from 6-12 per cent of nickel and 16 to 20 per cent of chromium preferably 8 per cent of nickel and 18 per cent of chromium. Welding may be effected with a current of the order of 300,000 amps. per sq. in. of electrode point under a pressure of the order of 3500 lbs. per sq. in. of electrode point, the duration of the current being of the order of <1>/25 to <1>/1200 of a second or less, preferably <1>/200 of a second in metal of 0.008 to 0.04 ins. gauge. The metal in the weld is stated to be quenched by the surrounding metal, the temperature in the region surrounding the welds being limited to temperatures below the critical temperature at which its anti-corrosion characteristics are substantially reduced, e.g. below 800‹ C. The welds 24, Fig. 4, preferably do not reach to the exterior surface of the metals. Heating is stated to be mainly due to the high mass resistance of the metal. The heat is stated to be generated in excess of that ordinarily producing damaging effects in the metal but for such a short period as to prevent such effects, e.g. <1>/64 to <1>/500 of a second or less, preferably <1>/200 of a second. Stainless steel strip may be initially hot rolled, then cold rolled, then sectioned by rolls, then cut to lengths. The portions where the ends of the elements are to be formed may be flattened by the rolls or by die-stamping subsequent to cutting into lengths to form the lapped portions. In Figs. 1 and 2, the channelled chord elements 10, 11 of a wing rib structure of an aeroplane are formed with flattened portions 13 which are spot welded to trusses 12. In Fig. 3, cover sheets 16 with channel ribs 17 at one end are spot welded to each other at 19, 20 and to annular frames 15 of a fuselage body structure at 18.

Title: Liquefied gas fueled lighter
IPC: F23Q2/173
Filed: 1966-03-04
Abstract: 1,118,351. Gas-fueled lighters. MANSEI KOGYO K.K. 4 March, 1966 [5 March, 1965], No. 9491/66. Heading F4F. A fuel control valve in the reservoir 10, e.g. of steel, bronze or synthetic resin, of a liquefied gas-fueled lighter, comprises a cylindrical valve body 11 which projects through the upper and lower walls 10a, 10b of the reservoir and contains a porous mass 20, e.g. of rubber, resin sponge, leather or cloth, for converting the fuel from the liquid to a gaseous state which is sandwiched between sheets 17 and 18 of fine wire mesh or perforated metal. The sheet 17 is retained within a circular flange 19 of a member 15, having a valve opening 24, which is made to compress the mass 20 against the action of a spring 14 by a cylinder 13 screwthreaded into the valve body 11. Rotation of a serrated knob 12 which meshes with the cylinder 13 varies the compression of the mass 20. A longitudinally bored burner nozzle 27 retains at its lower end a plug 26, e.g. of synthetic rubber, which in the inoperative condition of the lighter seals in a conical portion 40 of member 15, thus closing valve opening 24. To operate the lighter a forked lever 28 lifts nozzle 27 against the action of a spring 27 and gas from mass 20 flows into the nozzle through lateral openings 27b, 27c to the outlet 27d. Liquid fuel enters the control valve through lateral openings 11f and 11g in body 11 and passes into an absorbing mass 31 retained in a member 30 before being distributed by sheet 18 into mass 20. The member 30 is screwthreaded into valve body 11 and can by rotation affect the compression of mass 20. O-ring seals 23, 33 and 35 prevent gas escaping to atmosphere. In an alternative embodiment, Fig. 2 (not shown), the valve body comprises two screwthreaded parts 111, 112 and the members 13 and 15 are united into one piece 113. The valve body extends only through the upper wall of the reservoir eliminating member 30 so that absorbing mass 31<SP>1</SP> is retained by the valve body and is in direct contact with the liquefied fuel. In the embodiment of Fig. 3 (not shown), sheet 18 is replaced by a mass 114 of absorbing material squeezed within a cylinder 115 of soft synthetic resin or rubber.
