Abstract
237,901. British Thomson-Houston Co., Ltd., (Assignees of Palmer, R.). July 30, 1924, [Convention date]. Hearing by chemical action and molecular combination.-The adjoining portions of metal members or added metal supplied between the parts, or both, are fused to form a malleable joint devoid of oxides, nitrates, carbides, &c. by the heat developed by the reassociation of the atoms of dissociated hydrogen. An arc is struck between the ends of a pair of tungsten or like substantially non-consuming electrodes 1, 2 arranged at an angle or in line, and a jet of hydrogen is passed from a valved pipe 5 through a nozzle 28 of molybdenum or like refractory metal, transversely across the arc. The hydrogen is thus dissociated and impinges on the work, whereupon it is reconverted into molecular hydrogen and the heat evolved fuses the parts to be joined. Air is excluded by excess of hydrogen from the nozzle or by supplying hydrogen through dents in a metal cover plate 21 from a valved pipe 23. The electrodes are surrounded by lava bushings 24, 25 and may be clamped to. magnetic cores 10 enclosed in holders 3, 4 secured to insulating blocks 26, 27. The cores are withdrawn to strike the arc against the action of adjustable springs 18 by coils 11, 11<1> connected in series with the electrodes to a source or alternating or direct current. With a separation of about “ inch between electrodes of about “ inch in diameter, a current of 40 amperes at 300 volts may be used, the distance between the electrodes and the work being about 1 inch. The parts may be provided with a heat protecting shield 30 and may be mounted on an insulated bracket 29. The apparatus may be portable or may be traversed with respect to the work or may be stationary with respect to traversed work. Specification 237,898 is referred to.
