Abstract: An emission control device and method are provided for treating exhaust gases to reduce gaseous pollutants contained therein. The device includes a treatment chamber through which the exhaust gases pass. First and second metal screens are disposed within the chamber a predetermined distance from each other. AC voltage is supplied to adjacent the first screen with, for example, an electrode device. A timing circuit is provided for pulsing the AC voltage at a predetermined pulse rate. A temperature sensitive device may be interfaced with the treatment chamber and timing circuit so that the pulsed voltage is only supplied to the screen within a predetermined temperature range.

Abstract: Organic peroxide compositions that are available as sprayable dispersions, pourable dispersions, thick pastes and free flowing powder form, all of which may be characterized as slow burning and nonexplosive. Benzoyl peroxide compositions are preferred and may contain up to about 70 weight percent peroxide while viscosity of dispersions of same may be as low as about 100 centipoises when measured with a Brookfield RVT viscometer using a number 3 spindle at 50 rpm. Dispersions are produced in either low shear, impact-attrition type dispersion mills, exemplified by a Kady Mill, or high shear dispersion mills, exemplified by an Eppenbach Homo-Mixer.

Abstract: A method for fastening rock bolts in geological strata and a two-compartment package containing expansible resinous composition including unsaturated polyester resin syrup, aluminum chlorohydroxide and activator for the resin syrup. The method introduces an expansible composition into an opening in the geological strata, and foams the composition in engagement with a rock bolt. The preferred method introduces a two-compartment package of the composition into the opening in the geological strata, ruptures the package with the rock bolt, and mixes the composition by mechanical motion of the rock bolt.

Abstract: A golf training aid comprising an alignment band which is attached to a pair of spaced apart mounting points to establish a straight baseline, a first tension member one end of which is attached to one of the mounting points and a second tension member one end of which is attached to the other of the mounting points, the other ends of the tension members being secured to the head of a golf club; the tension members urging the head of the golf club into alignment with the baseline established by the alignment band to enable a golfer to practice the proper movement of various golf strokes against tension while discerning and maintaining the alignment of the selected hitting area of the head of his club with the desired path of movement. The mounting points may be defined by mounting bases provided with a top recess for receiving a chair leg and/or with an aperture through the bottom through which a peg may be extended into the ground.

Abstract: A foamed, low density, highly extended, polymerized unsaturated polyester resin product which exhibits excellent fire, strength and insulative properties. The product is formed by combining a first component comprised of unsaturated polyester resin syrup, reactive, non-reinforcing, extender material capable of providing a blowing agent nd selected from the group consisting of inorganic carbonate compounds, inorganic bicarbonate compounds and mixtures thereof and, optionally, non-reactive, non-reinforcing extender material with a second component comprised of an aqueous solution of aluminum hydroxie chloride and, optionally, non-reactive, non-reinforcing, extender material. When the two components are combined as a composition mixture, the reactive, non-reinforcing, extender material and the aluminum hydroxie chloride solution react to provide a blowing agent and to form a solid product which chemically binds the water originally present.

Abstract: A highly extended,unsaturated polyester resin syrup composition mixture comprising unsaturated polyester resin syrup, basic aluminum chloride and non-reinforcing extender material which is substantially non-reactive with the resin syrup and the basic aluminum chloride. The composition mixture may be used to prepare a shaped article comprised of the cured, cross-linked composition. The article is prepared by first forming a first component comprising unsaturated polyester resin syrup and non-reinforcing extender material and a second component comprising a solution of basic aluminum chloride and non-reinforcing extender material. The two components are mixed together to yield the composition mixture which possesses a viscosity low enough to be worked with conventional apparatus. The composition mixture is then shaped into the configuration of the desired article, allowed to cure and, if necessary, allowed to set.

Abstract: Semisolid polymerizable compositions are obtained by combining unsaturated polyester resin syrup, aqueous alkali-stabilized colloidal silica and finely divided particulate calcium sulfate hemihydrate. The composition rapidly thickens to a semisolid state when the ingredients are mixed and retains its semisolid condition for extended periods of time. The unsaturated polyester resin syrup component of the mixture remains polymerizable until its polymerization is initiated, normally by means of heating in the presence of a high temperature polymerization initiator. Sufficient calcium sulfate hemihydrate is included to react with substantially all of the uncombined water in the other ingredients so that the resulting polymerizable composition is substantially free of uncombined water. The compositions may also contain inert fillers and/or reinforcing fibers. The compositions can be employed to produce coatings, laminates, cast articles, molded articles and other shaped articles.

The fillers may be present in amounts from about 0.1 to about 5 times the combined weight of aqueous alkali metal silicate and unsaturated polyester resin syrup.The compositions can be employed in coatings, laminates, cast articles, molded articles, or other shaped articles.
