Abstract: A method is described for neutralizing urushiol on surfaces (e.g., wearing apparel, skin, tools, pets, etc.) with an aqueous solution comprising a water-soluble chlorine-containing compound which is a stable solid at room temperature. The solutions are also useful for deodorizing low molecular weight thiols such as are present in skunk spray or glandular secretions of other small animals. Because the chlorine-containing compounds are stable solids, they can be shipped and stored in solid form and dissolved in water at the time of use.

Abstract: A improved mold, apparatus and method for injection molding is provided. The apparatus is of the type which includes a means for opening and closing a multi-part injection molding mold, means for supplying molten material under high pressure into the mold cavity when the mold is closed and means for removing articles molded in the cavity on cooling. The improvement is provided by a new multi-part mold which is made up of at least two parts. Each part of the mold comprises a mold block portion having a ceramic mold cavity insert. The ceramic mold cavity inserts define the walls of the mold cavity when the mold is closed. Each mold cavity insert comprises a shaped ceramic body having a mounting surface adapted to fit under compressive stress throughout the entire molding operation within a mounting cavity of the mold block portion.

Abstract: A technique is described for neutralizing unishiol. The technique involves contacting urushiol with a chlorine-containing compound in a liquid medium. In one embodiment the chlorine-containing compound is sodium or calcium hypochlorite in an aqueous solution. In another embodiment the chlorine-containing compound is a chloramine in a liquid organic medium.

Abstract: An indicator (10) for detecting contact with a naturally occurring polyhydroxyaromatic skin irritant or toxin like that found in poison ivy and the like comprises a carrier (12) treated with a reactant, such as ferric nitrate which reacts with the toxin and produces a distinct color change indicative of such contact.

Abstract: A cartridge for a catalytic ozone converter comprising an aluminum honeycomb core, a tubular metal shell surrounding the core and affixed thereto, metal rib support members fastened to the shell and to the honeycomb core, and a catalytic coating deposited upon the cell walls of the honeycomb core.

Abstract: A method for preparing porous ceramic or metallic coatings on substrates and preparing perforated articles which are ceramic or metallic; the method involving utilization of a composition comprising ceramic powder or metallic powder, binder, and solvent whereby at least a portion of the solvent is rapidly volatilized to obtain the porosity in the ceramic or metallic material. The coated substrates and perforated articles are useful for example, as prosthetic devices, catalyst supports, and bone supplementation material.
