Abstract: Compositions including at least one curable fluoropolymer are disclosed which include at least one functional group for crosslinking the fluoropolymer, a curative capable of crosslinking the at least one fluoropolymer selected from the group consisting of functionalized biphenyl-based compounds, various monoamidine and monoamidoxime compounds as well as bisamidine compounds and combinations thereof; and at least one cure accelerator which may be an organic peroxide or an organic peroxide in combination with a colorant. Adhesive fluoroelastomeric compositions comprising colorants are also provided. The compositions described provide beneficial physical properties, increased plasma resistance, unique adhesive properties and/or reduced contamination associated with use of external adhesives. Methods for forming articles which incorporate fluoroelastomers bonded to metallic surfaces are also provided.

Abstract: Closed-cell and/or open-cell cellular perfluoroelastomeric materials are described which may be adapted for use in sealing members and laminates which improve low temperature elastomeric properties of perfluoroelastomeric materials. A variety of unique medical devices based on cellular and solid perfluoroelastomers are also described. The closed-cell cellular perfluoroelastomers are formed by combining a perfluoroelastomeric composition and a curing agent with a plurality of microspheres and/or a gas generating agent at a temperature high enough to soften the perfluoroelastomeric composition, but not high enough to expand the microspheres or activate the gas generating agent and then further heating the composition, microspheres and/or gas generating agents to cure the elastomer, expand the microspheres and/or activate the gas generating agent.

Abstract: A set of numbered golf clubs made from a plurality of progressively lofted clubs, each club having a club head, a shaft fixed at one end to the club head, and a grip fixed to the shaft at the other end. A counterweight is positioned at the distal end of the golf club opposite the club head, and the length of the shaft and the weight of the head, the shaft, the grip, and the counterweight of each club are selected so that each club within the set has a lorythmic swing weight of less than A minus 6 points, each club preferably having a shaft of the same flexing properties. The club heads with the counterweight system provides the user with increased stability, control and power.

Abstract: The dialkylbenzene polyethoxy alkyl sulfonate is combined with a water soluble petroleum sulfonate surfactant to form an effective surfactant solution that is stable in high salinity environments. The surfactant solution is injected into an underground petroleum reservoir in order to recover crude oil therefrom.

Abstract: This invention concerns methods of imparting properties of scale resistance to surfaces upon which adherent scale is normally prone to form during contact with mineralized waters through the use of novel; polyurethane-type resins, characterized by containing pendant polyoxyalkylene chains attached to a basic polyurethane skeletal network.
