Patent number: 4842903Abstract: Corrosion preventives, e.g. for automobiles, comprise sepiolite clays with waxes, sulfonates e.g. SACI, optional solvents, oils, soaps provide high viscosity, high solids, corrosion-preventatives. Application can be by hot spray or hot melt, hot dipping, and other standard techniques. The sepiolite clays provide excellent anti-sag capabilities to the dry films without excessively increasing the viscosity of the coating material. Conventional thixatropes such as bentonites and other common organo clays usually drastically increase product viscosity and complicate pumping at room temperature.Type: GrantFiled: April 12, 1988Date of Patent: June 27, 1989Assignee: Ashland Oil, Inc.Inventor: Roger E.

Patent number: 4839194Abstract: A method is described for preparing tissue samples for use in diagnostic evaluation involving the rapid fixation, dehydration, and embedding of a tissue sample as well as rapid mounting of plastic sections to glass slides, dissolution of plastic and optimal staining of tissure components. The rapid and controllable fixation and the dehydration of the tissue sample utilizes the denaturing effects of microwaves on the proteins in combination with a heat sink. Alternatively, the dehydration of the tissue sample utilizes the principles of freeze drying. The tissue sample can be embedded using conventional paraffin embedding or plastic embedding techniques. Rapid penetration of plastic into the tissue is facilitated by microwaves, adhesion of plastic sections to glass slides is promoted by microwaves, as is the fast and optimal staining of tissue components. The method of this invention provides a very rapid technique for processing of tissue for diagnostic and analytic evaluation.Type: GrantFiled: July 5, 1985Date of Patent: June 13, 1989Assignee: Bone Diagnostic CenterInventors: Hartmut H.
