    摘要: A niobium-based superconductor is manufactured by establishing multiple niobium components in a billet of a ductile metal, working the composite billet through a series of reduction steps to form the niobium components into elongated elements, each niobium element having a thickness on the order of 1 to 25 microns, surrounding the billet prior to the last reduction step with a porous confining layer of an acid resistant metal, immersing the confined billet in an acid or a high temperature liquid metal to remove the ductile metal from between the niobium elements while the niobium elements remain confined by said porous layer, exposing the confined mass of niobium elements to a material capable of reacting with Nb to form a superconductor.

    摘要: Wave soldering or tinning machine comprising: a solder reservoir; a means that forms at least one solder wave having a laminar form and including a flat surface; a means for bringing a piece to be soldered or tinned into contact with the laminar wave; and means for injection of a gas in the vicinity of the wave comprising an injector located in a position adjacent to and downstream from the wave and provided with a wall facing the solder wave, wherein the wall has at least a first group of openings positioned so as to produce a first gas jet directed toward the flat surface of the solder wave.

    摘要: Various metal coatings have been used for many years to inhibit oxidation of metals exposed to the natural elements of the atmosphere over a period of time. Terne alloy coatings which normally contain about 20% tin and about 80% lead are some of the most popular metal coating treatments to resist corrosion. The special formulation of the present invention reformulates the terne coating to constitute a tin and lead based coating where tin constitutes at least 90% of the terne and lead amounts to less than 0.1% and preferably less than 0.05% of the terne. The low lead terne coating may also include antimony and bismuth to provide strength and hardness to the low lead terne formulation having corrosion resistive qualities similar to that of standard terne coating formulations.
