Abstract: A process and apparatus for making alkali cellulose having a desired predetermined degree of polymerization in which cellulose is steeped in an alkali hydroxide bath, generally 17-25% sodium hydroxide, and then passed through an RF treatment chamber where it is subjected to an RF energy field, to produce a controlled depolymerization thereof. Upon emergence from the steeping bath, the cellulose passes to an excess solution removing means, such as one or a series of pairs of nip rolls where the excess solution is expressed from the cellulose and the amount of absorbed alkali is controlled. Preferably, the excess solution is recovered and returned to the steeping baths. A second, lower concentration, steep bath may follow the RF treatment chamber.

Abstract: An .omega.-lactam having 4-12 carbon atoms, an oligomer thereof or a ring-opened polymer or an .omega.-amino carboxylic acid corresponding thereto, is heated in the presence of water and a metallic carbonate compound to obtain a metallic salt of .omega.-amino carboxylic acid. Barium, calcium and lithium are the preferred metals. The resulting metal salt is converted to an amino Schiff base which may be used as a starting material for preparing an .alpha.,.omega.-diamino alkane which may or may not include an amino group as a side chain. This further produces a metallic carbonate compound. The metallic carbonate is returned and used again as a reagent for forming the metal salt of the .omega.-amino carboxylic acid to create a closed system.

Abstract: Improved process and apparatus for making alkali cellulose comprises continuously steeping indefinite length sheets of cellulose in an alkali hydroxide bath, generally 17-25% sodium hydroxide, and then passing the cellulose strip through a chamber where it is subjected to extremely rapid mercerizing conditions, including an RF energy field, to produce depolymerization thereof. Upon emergence from the steep bath, the cellulose passes to an excess solution removing means, such as one or a series of pairs of nip rolls where the excess solution is expressed from the cellulose and the amount of absorbed alkali is controlled. Preferably, the excess solution is recovered and returned to the steeping baths. A second, lower concentration, steep bath may follow the rapid mercerization step.

Abstract: A process and mold for producing padded motor vehicle seat backs containing a metal framework surrounded by polyurethane foam in a plastic coating. The framework is inserted through a slit in the coating which is then sealed. Then the polyurethane foam is injected through a flexible filler neck into the coating and allowed to polymerize. After polymerization the filler neck is cut off. The framework may be contained in a plastic bag together with a relatively resilient foamed plastic body. The coating may be pressurized inwardly and pressure in the mold may be reduced during injection of the polyurethane foam. The mold comprises a pair of lateral mold parts and a central mold part together defining the mold cavity. The lateral mold parts are movable toward and away from the central mold part by hydraulic or pneumatic rams.

Abstract: An adjustable window guard and screen apparatus includes an adjustable framework of two sections slidably mated to each other. Also, at least one set of screen members, and a plurality of bar members are affixed to the framework and are expandable or contractable upon the adjustment of the framework. Louver members having two slidably mating sections are further included and are each in engagement with a bar member. At least one section of a bar member having a louver member mounted thereon, is itself rotatably mounted to the framework. The louver member is mounted to the bar member so that rotation of the rotatably mounted bar member section causes rotation of the louver member. Like the screen members and bar members, the louver members will expand or contract upon the adjustment of the framework.
