Latest Patents

One of Sprecace's latest patents is for a seal welded cast iron nuclear waste container. 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 that are bonded to the mating plug and main body components of the package. The welding inserts might be bonded in place during the 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 cast iron. The use of nickel-carbon weld inserts should eliminate any need for pre-weld and post-weld heat treatments, which are problematic to apply to nuclear waste packages. Although the waste package closure weld approach results in a dissimilar metal combination, the relative surface area of nickel-to-iron, their electrochemical relationship, and the presence of graphite in both materials will act to prevent any galvanic corrosion problem.

Another significant patent by Sprecace is a method of forming a wick for a heat pipe. This method is characterized by the steps of forming a wick blank of a predetermined thickness comprising a plurality of superimposed layers of stainless steel mesh screen. The blank is then wet rolled to reduce its thickness, wrapped about an inner mandrel, compressed into a rigid tubular structure, and finally sintered after removal from the mandrel.
