Abstract: A convenient storage catalog especially adapted to safely and efficiently store integrated circuit chips. The chips are removably mounted in a cataloged position upon a sheet of bendable material. The individual sheets of material have indicia formed thereon which divides either of the opposed faces of the sheet into a plurality of adjacent areas. Each of the areas further have indicia formed thereon related to the identification of the particular integrated circuit chip mounted thereon. The individual areas are of sufficient size to receive a plurality of integrated circuit chips. A plurality of sheets may be joined at one edge thereof to provide a loose leaf book, or alternatively, the sheets may be assembled within an enclosure to provide a filing cabinet.

Abstract: A compact portable electrically heated steam generator includes an electrical resistance heating element loosely centrally located within a flexible reinforced non-metallic tube through which the liquid to be converted to steam can flow. Grounded metallic inlet and outlet couplings are provided at the ends of the tube and the ends of resistance element is electrically connected thereto. At least one intermediate point of the resistance element is connected to a source of electricity in such manner that electrical current flows across the resistance element to ground so that the liquid flowing through the tube is heated and vaporized. A part of the resistance element is arranged to be under control of a temperature responsive switch having a temperature sensor downstream of the outlet coupling.
