Abstract: A grounding connector includes a frame with upper and lower arms cantilevered from a center section to form a channel adapted to receive a section of a structural steel member. The frame has a conductor receiving region in each of the cantilevered arms, each conductor receiving region being a slot extending through the frame having a longitudinal axis aligned substantially parallel to the frame. The conductor receiving slot on one side of the frame is sized to receive a conductor of a first size and the conductor receiving slot on the other side is sized to receive a conductor of a different size. The conductor receiving regions are located so that when the upper arm and the lower arm are compressed to grip the section of the structural steel member received in the channel, the conductor is crimped to the frame.

Abstract: Carbon--carbon composite parts are joined with minimum surface preparation. A reactive-bonding joint interlayer having thickness greater than 1 mil is formed of fine particles of carbide-forming metallic ingredients and carbon. The joint interlayer is sandwiched between the two carbon--carbon parts to be joined and the assembly is heated under a compressive pressure to a temperature sufficient to complete the bonding reaction. No special surface preparation is required for the carbon--carbon parts due to the nature of the reactive-bonding. The mechanical properties of the joint are assured by selecting the metal-carbon ingredients so that thermal expansion mismatch is minimized. Shear strength exhibited by the resulting joints is greater than the interlaminar shear strength of the carbon--carbon composite material.

Abstract: This invention relates to the property of a bonded metal including a forming material of a nickel-titanium alloy and its method of manufacture. This bonded metal property is produced by forming a forged structure to achieve an incorporated integral body through the bonding of the nickel-titanium alloy material onto another material of nickel base alloy. The manufacturing method used to achieve this property involves heating both materials at the point to be bonded in an inert gas atomosphere. The materials are first heated to their melting point and in this state are fused together under high pressure. This forms the forged structure on the portion of the materials so treated.

Abstract: A connection of an outer sheet metal member with an inner sheet metal member whereby the outer sheet metal member must form an optically smooth surface. For that purpose, the outer sheet metal member is folded over the inner sheet metal member and a welding seam is then made from the folded-over side by means of a low energy welding process, for example, special forms of the protective gas welding or energy beam welding, and more particularly in such a manner that only the folded-over part of the outer sheet metal member and the inner sheet metal member fuse. The non-folded-over side of the outer sheet metal member thereby shows no impairment whatsoever by the welded connection.

Abstract: This invention identifies methods and articles designed to circumvent metallurgical problems associated with hermetically closing an all cast iron nuclear waste package by welding. It involves welding nickel-carbon alloy inserts which are bonded to the mating plug and main body components of the package. The welding inserts might be bonded in place during casting of the package components. When the waste package closure weld is made, the most severe thermal effects of the process are restricted to the nickel-carbon insert material which is far better able to accommodate them than is cast iron. Use of nickel-carbon weld inserts should eliminate any need for pre-weld and post-weld heat treatments which are a problem to apply to nuclear waste packages.
