Abstract: A water closet shell comprising a basin component formed in one piece of molded plastics material and a cistern component likewise formed and when assembled defines a water closet unit having a flushing rim section. The flushing rim section is defined by mating an upwardly projecting ridge from the basin with a downwardly projecting ridge from the flushing rim.

Abstract: Phosphated locust bean gum is cold water soluble and does not require heat or high shear to form viscous solutions in water. Blends of phosphated locust bean gum and xanthan gums are also cold water soluble and such blends will form highly viscous gels in water without the application of heat or high shear agitation. Such gels are useful as suspending media for a variety of materials, e.g., seeds used in fluid drilling planting operations.

Abstract: Coating compositions are prepared from aqueous dispersions of polyhydroxy polyether resins and aminoplast or phenolplast resins or blocked polyisocyanates containing as a diluent an aqueous emulsion of a water immiscible alcohol. The coating compositions are particularly useful as can coatings.

Abstract: Polyepoxide resins are adducted with polyamines using an excess of the amine. After the adducting reaction is completed, the excess unreacted polyamine is removed. The adduct is then reacted with a monoepoxide or a monocarboxylic acid. When salted with an acid, the resinous adducts are water soluble or water dispersible. The resin solutions or dispersions are particularly useful in cathodic electrodeposition processes for prime coating metal objects.

Abstract: A process for the preparation of an open-celled microporous, polymer film. The improved process comprises the heat relaxing of a microporous polymer film which is formed from a non-porous, crystalline, elastic polymer film which has been uniaxially cold stretched at a temperature in the range of between about -20.degree. C. and a temperature 25.degree. C. below the crystalline melting temperature of the polymer film, followed by hot stretching, in the same direction, the cold-stretched film at a temperature in the range of between about 25.degree. C. below the crystalline melting temperature of the polymer film and 5.degree. C. below the crystalline melting temperature of the polymer film. The heat relaxing step comprises exposing the film under tension to a temperature in the range of between about 40.degree. C. below the crystalline melting temperature of the polymer film and 5.degree. C.

Abstract: Polyhydroxypolyether resins are prepared by reacting in water as a dispersion an epoxide compound which has more than one 1,2-epoxy group per molecule with a dihydric phenol. The reaction is conducted in the presence of a nonionic dispersant at a temperature of about 80.degree. C. to about 100.degree. C. using, as a catalyst, an organic phosphine, a tertiary amine, or a quaternary ammonium or phosphonium compound. The polyhydroxypolyether resins are useful in coating compositions, molding compounds, encapsulating compositions, adhesives and the like.

Abstract: The stability, particularly in the presence of unprotected ferrous metal surfaces, of pressure-sensitive adhesive compositions, made from a carboxylic acid containing acrylic polymer and chelate esters of orthotitanic acid, is improved by the addition of a small amount of a tertiary amine.

Abstract: Epoxy resin compositions having extended reactivity (gel time) are prepared by adding phosphate or phosphite compounds to epoxy resin-dicyandiamide-tertiary amine curing systems. Such compositions are useful in preparing glass fiber laminates and powder coatings.

Abstract: A process for producing a polyacetal polymer. The process includes reacting a polyacetal forming polymerization mixture in a polymerization reaction zone, which zone includes an elongated casing substantially following the outer boundaries of at least a pair of shafts, each of the shafts provided with a plurality of intermeshing elliptical shaped plates having flattened edges at the major axis which mesh, wiping the surface of its mating plate. The polymerization mixture is polymerized to form a polyacetal product in the form of a finely divided solid.

Abstract: A heat actuated valve comprises a base adapted to be mounted on a fire extinguisher container. The base includes a passsage communicable with the container interior. A pair of stop fingers extend forwardly from the base. A fusible element interconnects the stop fingers. The base, stop fingers and fusible element are of one-piece, integral construction. A plunger is slidably mounted in the passage and includes a passage-blocking portion which blocks the passage when the plunger abuts the stop fingers during a fire sensing mode of operation. The plunger is slidable rearwardly to shift the passage-blocking portion to a first passage-opening position to allow the container to be filled. The plunger is operable, in response to melting of the fuse, to spread the stop fingers apart and travel forwardly sufficiently to shift the passage-blocking portion to a second passage-opening position, enabling the container contents to be discharged.

Abstract: Coating compositions are prepared from aqueous dispersions of polyhydroxy polyether resins and aminoplast or phenolplast resins catalyzed with adducts of phosphoric acid and glycidyl polyethers of polyhydric phenols. The coating compositions are particularly useful as can coatings.

Abstract: A container comprising a blow moldable thermoplastic frame defining a volume for the storage of a fluid. The thermoplastic frame is opaque barring the transmittance therethrough of light having a wavelength in the range of between about 3500 and 5500 Angstrom units. The container is further characterized by an overwrap of a thermoplastic film disposed about the thermoplastic frame. The overwrap film is characterized by its ability to bar the transmittal therethrough of oxygen. The container is especially suited for the storage, at or near ambient conditions, of liquid food subject to spoilage by the action of light waves, oxygen and odor permeation.

Abstract: Powder coating compositions are prepared by first forming a dispersion in water of a complex polyhydroxy polyether resin using as the dispersant an inorganic or organic base salt of a polymeric carboxylic acid having an acid value before salting of at least 50, acidifying the dispersion and then isolating and drying the precipitated fine particle size resin. Such resins in this finely divided form find particular utility as powder coatings for metallic articles.

The electrostatic pinning means, which significantly improves pinning of a thermoplastic polymeric film cast upon a moving surface, by electrostatic force, is precisely positioned, in relation to an extrusion means and the moving surface, by means of the precision positioning apparatus. The apparatus includes a frame moveable in vertical and horizontal directions. The apparatus further includes the pinning means and support means, connected to the frame, for holding the electrostatic pinning means. Horizontal and vertical adjusting means comprising horizontal and vertical actuating means connected to horizontally and vertically moveable means responsive to the horizontal and vertical actuating means, respectively, are connected to the frame to permit separate horizontal and vertical movements to precisely position the electrostatic pinning means.

Abstract: Vinyl acetate based aqueous dispersion having improved wet adhesion properties are prepared by copolymerizing vinyl acetate with about 3 to about 10 percent by weight of a polyacrylate ester and about 0.5 to 3 percent by weight of hydroxymethyl diacetone acrylamide, said percentages being based on the total weight of the copolymer. Optionally, other monomers copolymerizable therewith can be included in the copolymer. Aqueous dispersions of this invention have utility as vehicles in protective coating formulations.
