Abstract: Welding equipment particularly for arc-welding a junction of two wires, for example, for forming a thermocouple junction wherein the junction is held by means of a gripping unit of substantial heat capacity, the gripping unit consisting of two constituent elements which can be displaced with respect to each other so as to vary the aperture defined between the elements and designed to receive the junction.

Abstract: The invention provides metal oxide film structures for use as radioactive radiation windows, membranes of electrolytic cells and other purposes. The structures consist of an annular, or other closed frame of tantalum, niobium, tungsten or zirconium integral with a thin film of an oxide of the same metal, which spans the area enclosed by the frame. The structure is manufactured by subjecting a blank of the metal concerned, centrally masked on the larger part of the surface, to an anodizing treatment producing the oxide on all not-masked parts, removing the mask and subjecting the oxide-covered blank, as anode, to an electrolytic process by which the not-oxidized metal except the marginal portion, which constitutes the frame, is dissolved.

Abstract: Electrolytic working of metal or mineral bodies. An electrolytic circuit is established using nitric acid as electrolyte and cathodes which are inert to the electrolyte under the operating conditions and the body to be worked is immersed into the electrolyte and brought into direct contact with, or close proximity to, the cathode. A current is flown through the circuit and by this the body is bored, cut or the like according to the specific arrangement.
