Abstract: A surgical guide includes a body including a beveled distal surface configured to being placed against a side of a foot and a proximal surface. The body includes at least one channel that extends between the beveled distal surface and the proximal surface of the body. At least one K-wire is receivable in the at least one channel and is configured to being received in a metatarsal and a capital fragment of the foot. The guide includes a handle, and a preset angle is defined between a longitudinal axis of the body and the beveled distal surface of the body. The preset angle is between approximately 25° and approximately 30°.

Abstract: This disclosure relates to systems and methods for repairing bone deformities. The systems may include one or more guides for positioning instruments relative to bones and/or joints.

Abstract: A method for predicting the hydrocarbon/water contact level for oil and gas wells which relates porosity .phi., water saturation S.sub.w, air permeability k.sub.a, and capillary pressure P.sub.c. Such contact level may be estimated without actual capillary pressure measurements. The method relies on a worldwide correlation of permeability and porosity to a function of capillary pressure. The hydrocarbon/water contact levels are predicted through regression analysis using porosity .phi., water saturation S.sub.w, and air permeability k.sub.a from well log and core analysis information. Relationships used in this method include ##EQU1## where P.sub.c is mercury capillary pressure, F.sub.g is pore geometrical factor, S.sub.w is water saturation, P.sub.d is mercury displacement pressure, k.sub.a is air permeability, and .phi. is porosity. The constants set forth in equations (b) and (c) above may be adjusted to fit measured data from rock samples within the reservoir.

Abstract: The tetramethylol derivative of 4,4'iso-propylidenediphenol is dissolved in a solution of water and ethylene or propylene carbonate to yield concentrated solutions of the derivative in a form which may readily be used in the manufacture of foams or used as a liquid binder for molded ceiling products. Based on 100 parts by weight of the tertramethylol derivative, these solutions contain from about 15 to about 35 parts by weight of water and from about 5 to about 30 parts by weight of ethylene carbonate or propylene carbonate, with the total parts by weight of the water and carbonate varying from about 40 to about 45.

Abstract: A phenolic foam produced without the use of a conventional chlorofluorocarbon or hydrocarbon blowing agent is disclosed. The phenolic foam is produced as the reaction product of a mixture comprising a phenolic resole, a surfactant and stannous chloride. The phenolic foams can be formulated to contain a substantial proportion of closed cells.

Abstract: An elastomeric polyester curable at room temperature by photoirradiation is disclosed. This composition comprises as a resin component:(1) 15% to 50% by weight of an unsaturated polyester resin prepared by reacting tetrahydrophthalic anhydride or endic anhydride; optionally, an aromatic dicarboxylic acid or its equivalent; a diol having an allyl unsaturated group pendant from the diol chain; and optionally, an alkylene diol; and(2) 85% to 50% by weight of a methylolated phenolic crosslinking agent; and 0.5% to 5.0% by weight based on said resin component of a metal halide photoinitiator.

Abstract: A decorative non-vinyl flooring composition is described which comprises a mineral filler distributed substantially uniformly throughout a binder comprising a blend of a copoly(C.sub.1 to C.sub.8 alkyl acrylate/C.sub.6 to C.sub.12 cycloalkyl acrylate) and a chlorinated polyethylene.

Abstract: A non-vinyl flooring composition is described which comprises a mineral filler distributed substantially uniformly throughout a binder comprising a blend of a heteropolymer comprising at least two C.sub.1 to C.sub.8 linear or branched alkyl acrylates of Mw from about 100,000 to about 300,000 and further characterized by at least two glass transition temperatures, one being above 25.degree. C., the other being below 25.degree. C., and a random ionic copolymer of an .alpha.-olefin and an .alpha.,.beta.-unsaturated carboxylic acid having 10% to 90% of the carboxylic acid group neutralized with metal ions.
