Abstract: A welding method and means is disclosed utilizing a conductive foil disposed between or adjacent members to be welded together with the foil serving as one electrode and one or both of the members serving as another electrode of the welding circuit and with the members being forced together or with the foil being forced against the members by a separate electrode.

Abstract: An interconnection system suitable for transmission lines, in the form of electrical or optical conductors, or in the form of conduits for electrical waveguide transmission, reflected light or fluidic signals, wherein lengths of such transmission lines bridge between discrete point-to-point location on a substrate, the transmission lines being anchored by sealant and filler material at selected substrate locations and being cut generally transversely, or otherwise transversely formed, to provide exposed conductor or conduit end portions anchored at the selected locations. The transverse areas of the conductors or conduits defined by such transversely cut, or otherwise transversely formed, and exposed end portions provide energizable signal energy planes. More specifically, such discrete energizable planes in the form of transverse conductor surfaces, are of a size and shape conforming to the transverse conductor areas exposed by cutting or other forming operation.

Abstract: A crimped corrosion proof terminal for crimping onto solid or stranded aluminum wire is disclosed. The precrimped combination includes a tubular, plated copper terminal, the forward portion of which is flattened and closed and the rearward portion houses a perforated insert. The rearward portion of the terminal carries an insulation sleeve disposed on a metallic ferrule. The rearward portion of the ferrule houses a bushing. This assembly is crimped such that the resulting crimped terminal and wire are progressively reduced in diameter in a stepwise fashion, a forward deeply crimped portion elongates and is provided with a reservoir which substantially fills with extruded wire.The forward portion of the termination incurs the greatest reduction and the rearward portion the least. The crimping causes the aluminum wire to extrude through the perforations in the insert, thereby establishing good electrical contact between the wire and the terminal by breaking the aluminum oxide film on the aluminum wire.
