Abstract: Method, apparatus and program product are provided for the invalidation of faulty metadata in a storage controller coupled to a host device. Faulty metadata may include metadata which no longer matches the associated customer data tracks stored on a DASD or other storage device. When faulty metadata is detected, metadata tracks are selected to be invalidated. A command is received through a host interface, without the controller being taken off-line from the host, and the specified metadata tracks are invalidated. Subsequently, the invalidated metadata tracks are rebuilt. The disclosed method, apparatus and program product invalidate the faulty metadata with reduced impact on normal host/controller I/O operations.

Abstract: A non-welded deck used to support insulation from the roof of a low temperature or cryogenic storage tank is disclosed. The deck may be comprised of a plurality of spaced apart bars with metal sheets covering the spaces between the bars. The edge of the metal sheets may be clamped to the bars to form the deck. The edges of adjacent metal sheets may overlap and be clamped together in such a way as to deform the sheets creating a metal-to-metal vapor and dust proof seal. The plurality of clamping bars and support bars may secure the metal sheets with sufficient strength to allow the entire deck to support loadings as a stressed membrane. The tank may be constructed with hardware that remains secure even after being subjected to repeated thermal cycling of over 200° Celsius (360° Fahrenheit).

Abstract: A high foaming light duty, liquid detergent with desirable cleansing properties and mildness to the human skin comprising a water soluble nonionic surfactant as the major active ingredient, a supplemental amount of a water soluble, foaming, alkyl ethoxylated ether sulfate anionic surfactant, an alkyl sulfate surfactant, and a water soluble, foaming zwitterionic betaine surfactant and the balance being water.

Abstract: A high foaming, light duty liquid detergent with desirable cleansing properties and mildness to the human skin composing: a water soluble nonionic surfactant; a ethoxylated alkyl ether sulfate anionic surfactant, a zwitterionic betaine surfactant and the balance being water.

Abstract: A high foaming, nonionic surfactant based, light duty, liquid detergent with desirable cleansing properties and mildness to the human skin comprising three essential surfactants: a water soluble nonionic surfactant; supplemental amount of a water soluble, foaming, sulfate anionic surfactant, a lesser amount of a water soluble, foaming zwitterionic betaine surfactant and the balance being water.

Abstract: A high foaming, nonionic surfactant based, light duty liquid detergent with desirable cleansing properties and mildness to the human skin comprising: a water soluble nonionic surfactant; at least one water soluble or dispersible foaming, anionic surfactant; a zwitterionic betaine surfactant, and a dialkyl sulfosuccinate ester.
