Title: "warmfoot" instant-subflooring instant-subflooring
Inventor: RENIAK NORMAN B
IPC: E04F15/18
Filed: 1992-09-21
Abstract: Re: Application for Patent on Instant Sub Flooring.          Abstract:          In the flooring industry it is known that many methods have been implemented to provide insulation or heat to concrete flooring.  It is also known several varying chemical compounds (paint, adhesives, bonding agents and sealers) have been used toreduce the moisture secretion from concrete as sealing the concrete was imperative to ensure moisture did not hamper or disturb the finished floor surfacing materials used, eg. tiles, hardwood, linoleum, underlayment or carpet, together with their respective bonding or sealing agents.  It is also known the primary material used to produce a sub floor of minimal hiegth on a concrete base is wood studs with a plywood cover sheeting.          In this invention, the Instant Sub Flooring material is impermeable to moisture but still allows air movement to flow between the spaces to naturally dry the moisture secretion from the concrete, allowing floor finishers to complete their job without worrying about moisture presence.  The newly invented Sub Flooring material is 3/8" in hiegth which provides an insulating barrier of air between the concrete base floor and the floor finishing materials.  It also provides a reduced hiegth factor.  Instant Sub Flooring also prevents mildew smells and carpet rot because of the raised floor.  The design also provides super strength capabilities for heavy loading.

Title: Water inactivatable pressure sensitive adhesive
Inventor: THERRIAULT DONALD J
IPC: C09J151/00
Filed: 1993-01-29
Abstract: A novel polymeric pressure-sensitive adhesive formulation is provided comprised of  a balanced hydrophilic/hydrophobic  base polymer compounded with at least one water-soluble tackifying component.  Upon contact of the pressure-sensitive adhesive with excess amounts of water, the water-soluble tackifying component is caused to separate from the base polymer,  thus decreasing the ability of the base polymer to function as a pressure-sensitive adhesive.  The adhesive may subsequently be easily removed from any substrate to which it has been applied.

Title: Stable isoforms of creatine kinase for standard markers and diagnosis
Inventor: PERRYMAN M BENJAMIN
IPC: C12N9/12
Filed: 1993-04-16
Abstract: ABSTRACT     The invention relates to stable isoforms of creatine kinase (CK) subunits.  Recombinant subunits may be expressed in cells cotransfected with DNA encoding one or more wild-type creatine kinase subunit B, wild-type subunit M or mutant M CK subunits.          The subunits and dimeric species produced by association of the monomeric units are indistinguishable in electrophoretic mobility from creatine isoforms produced in vivo. The various isoforms are useful as analytical standards in commonly used tests to determine the presence of creatine isoforms.  The disclosed isoforms have good storage stability and are stable under conditions employed for nondenaturing electrophoresis.
