Abstract: The invention relates to adhesive compositions for gluing wood containing aqueous vinyl ester graft copolymer dispersions and water-soluble acid metal salts or free acids, in which the adhesive compositions exhibit outstanding resistance to hot water and have high storage stability. The vinyl ester graft copolymer comprises from 2 to 12 percent by weight, based on the total weight of the graft copolymer, of one or more polyvinyl alcohols having a degree of hydrolysis of from 60 to 99 mol persent and 88 to 98 percent by weight, based on the total weight of the graft copolymer, of a grafting monomer mixture. The grafting monomer mixture contains from 5 to 50 percent by weight, based on the total weight of the monomer mixture, of vinyl esters of saturated, highly branched aliphatic monocarboxylic acids having 9 or 10 carbon atoms, vinyl pivalate, diisopropyl maleate, diisopropyl fumarate, vinyl chloride and mixtures thereof.

Abstract: An apparatus for pressure deforming a hollow workpiece having a tubular end portion has a die formed with a cavity adapted to receive the workpiece with the end portion of the workpiece projecting out of the die and a fitting movable along an axis toward and away from the die and formed with a seat sealingly engageable in a feed position over the projecting end portion of the workpiece. An annular self-tightening gland in the seat circumferentially engages in the feed position around the projecting end portion of the workpiece. A passage opening in the seat into the hollow workpiece when the fitting is engaged over the projecting end portion serves for pressurizing an interior of the workpiece and thereby deforming it outward against an inner surface of the die and for pressing the gland radially tightly against the workpiece and against the fitting.

Abstract: The efficiency of vinyl acetate production is increased by scrubbing of off gas followed by CO2 absorption. A portion of the off gas containing substantial quantities of ethylene is recycled to the process, whereas another portion is employed in another ethylene consuming reaction. Despite not removing non-reactive gases, selectivity and yield based on ethylene are both increased.

Abstract: A hollow workpiece having a tubular end portion is deformed by first fitting the workpiece into a die formed with a cavity adapted to receive the workpiece with the end portion of the workpiece projecting along an axis out of the die and then engaging over the projecting end portion of the workpiece a feed sleeve in a pressure-tight fit. The sleeve and workpiece are supported relative to each other such that the holding portion can slide in the sleeve and that the sleeve exerts substantially no axial force on the workpiece. Then an interior of the workpiece is pressurized through the sleeve and to deform the workpiece outward against an inner surface of the die.
