Abstract: A composition for and method of removing polymeric material from a porous media such as a subterranean formation. The method comprises contacting the polymeric material with an aqueous composition having a pH of from about 2 to about 10 and comprising an oxidizing agent, a water soluble carboxylic acid, and optionally, a source which is effective in promoting the decomposition of the oxidizing agent.

Abstract: This invention provides tobacco compositions which contain a hydroxy-substituted carboxylate compound as a flavorant additive.In one of its embodiments, this invention provides tobacco compositions which contain a hydroxy-substituted alkanoate flavorant additive such as ethyl 2-(2-butyl)-3-hydroxy-3-methyl-33-phenylpropionate: ##STR1## Under smoking conditions the above illustrated hydroxy-substituted alkanoate additive and its pyrolysis products flavor the mainstream and sidestream smoke.
Abstract: An improved process for preparing a sticky water-soluble polymer, e.g. acrylamide polymers and acrylic acid polymers, which comprises polymerizing an aqueous solution of a monomer in a polymerization vessel of which the surface contacting the aqueous monomer solution is covered with a tetrafluoroethylene-ethylene copolymer film, whereby the stickiness of the produced polymer to the vessel is remarkably decreased, namely the peelability of the polymer from the vessel is remarkably improved, and moreover the polymerization conversion is remarkably improved. Also, the use of a metal deposited tetrafluoroethylene-ethylene copolymer film as a covering material improves the efficiency of a photopolymerization and enables to use a polymerization vessel made of an inexpensive material.
Abstract: Acetylene and other 1-alkynes are polymerized by a catalyst system comprised of a transition metal complex consisting of at least one binucleating ligand attached to at least one transition metal containing nucleus; and at least one organometallic cocatalyst containing at least one element of Group 1a, 2a or Group 3a.

Abstract: A method and apparatus for rapidly dispersing particles of dry, water soluble polymer into water wherein air, water and said polymer particles are introduced to a chamber for thorough contact of the polymer with the water to form a mixture of aqueous polymer dispersion and entrained air. The mixture is immediately subjected to shear forces to separate any agglomerated particles into individual particles, and to prevent further agglomeration.
Abstract: An improved method of making lead or tin based alloy badges or emblems having brilliantly colored closely spaced cloisonned areas into which the desired colors can be introduced. The cloisonned areas separate the differently colored sections from each other by the formation of slight ridges or low fences into which the differently colored paints can be introduced. After the differently colored paints or other colorings have been introduced into the cloisonned areas and dried, the badge or emblem is polished to expose the ridges or fences separating the cloisonned areas and any other raised areas which it is desired to emphasize. The badge or emblem is then plated with an appropriate plating to cover the raised cloisonned areas and any other raised areas which it is desired to highlight. The resulting badges or emblems have clearly defined brilliantly colored sections and embody remarkable detailed structures.
Abstract: The invention provides a method to liquify a heavy brine completion fluid containing chlorides. The combination of a persulfate and hydrogen peroxide was found to be more effective than either compound alone, or than a peroxygen plus an activator.

Abstract: A perforated structure of expanded material, including at least one solid unstretched strip (4) parallel to the direction of expansion and of a length less than the length of the expanded region. The expanded region is formed with a tool that simultaneously cuts or perforates and expands the material.
Abstract: A flat panel display of the type in which an electrode structure is disposed in a vacuum chamber between a front glass panel and a foil backing sheet is provided with a gas-impervious electrical connector sealably mounted over an opening in the foil sheet so as to be physically held in place within the panel by the ambient pressure on the exterior side of the connector.
Abstract: Olefins are polymerized in the presence of catalysts prepared from titanium compounds prepared by reacting a titanium compound such as titanium tetraisopropoxide with a compound containing at least one aliphatic hydroxyl group.
