    摘要： A solvent-based thermosetting coating composition comprising a hydroxy functional urethane modified polyester resin and blocked polyisocyanate crosslinking agent. The coating composition may be formulated as a hot sprayable, high solids coating composition suitable for use as chip resistant automotive vehicle primer suitable for use on body panel areas subject to chipping by stones, gravel and other road debris. Alternatively, the composition may be formulated as a high solids composition sprayable with conventional spraying equipment. The hydroxy functional urethane modified polyester resin is the product of polymerization of lactone monomers in the presence of hydroxy-containing urethane modified polyester precursor. The polymerization reaction mixture comprises between about 10 and about 80 weight percent the hydroxy-containing urethane modified polyester precursor and between about 90 and about 20 weight percent lactone monomers.

    摘要： Process for the manufacture of sodium hydroxide in a sustained manner, tolerant of upsets in sodium hydroxide concentration, by electrolysis of sodium chloride at about 70.degree.-110.degree. C. in an electrolysis cell separated into a cathode compartment and an anode compartment by a cation exchange membrane, wherein the membrane is made of a copolymer of tetrafluoroethylene with a perfluoro monomer Z having a defined structure and a carboxyl end group, the mole ratio of tetrafluoroethylene to the monomer Z in the copolymer being about 7.6 to 8.2, the membrane material on the side exposed to the catholyte being nonporous but having a porous catholyte diffusion layer in direct contact therewith or in close proximity thereof. The sodium chloride feed solution is about equal to the concentration of saturated brine at the operating temperature, and the concentration of sodium chloride solution leaving the anode compartment is about 18-24%, no water being added to the catholyte during steady state operation. In this manner, 42-54% sodium hydroxide can be made with current efficiencies of about 90-97%.

    摘要： A self-erecting end-loading top-dispensing container which is convertible from a substantially flattened configuration for shipping the empty container into an erected box-like configuration for loading product into the container and for shipping loaded containers. By removing a tear-away portion of the top panel, the container is convertible into a tray having an open top for dispensing product. Connecting webs join the end closures of the container to the front and rear side walls, preserving the structural integrity of the container when the removable top is torn away.

    摘要： An apparatus and process for uniformly mixing a relatively small amount of material with a relatively large amount of another material in particulate form by introducing the smaller amount of material via a pipe within another concentric pipe through which a high pressure gas is introduced which thereby provides a zone of turbulence into which a particulate material in larger amounts is introduced, the mixture of gas and materials being transported through a treatment chamber to produce a uniform mixture.
