Abstract: A container for holding various articles and which contains a moisture control system for reducing humidity within the container. The moisture control system prevents moisture from penetrating in the interior of the container and reduces humidity that enters the interior when the lid of the container has been opened. The moisture control system comprises a moisture cup that is received within an opening in the container, a desiccant holder that is carried by the cup, a mesh screen that is dimensioned to receive a desiccant and a top. The moisture cup performs three functions: (1) it prevents moisture from penetrating the interior of the container through the opening; (2) it directs moisture from within the interior of the container to the desiccant; and (3) it holds the desiccant. In order to more conveniently transport the detergent, a strap is attached on each side of the container.

Abstract: Mandrels for use in the manufacture of nickel shells by vapour deposition of nickel from gaseous nickel carbonyl. The mandrels comprise a body formed of a composite material of a matrix, for example, a ceramic material or an organic polymeric compound, and a filler, for example, metal, metal oxides, carbon in particulate form and having the same coefficient of thermal expansion as nickel. The invention includes processes of manufacturing the shells using the composite mandrel and shells made thereby. The shells have improved non-deformability in operation and are of use as molds in the mass production of plastic articles.
