Publication number: 20060029654Abstract: The present invention relates to a method for topical treatment of pain resulting from a sports injury, including injuries to bones and soft tissue, such as ligaments, muscles or tendons. The method includes the steps of: applying to skin of a subject suffering from pain resulting from a sports injury a transdermal drug delivery system comprising a formulation comprising a pain-relieving amount of a local anesthetic and a pharmaceutically acceptable carrier, wherein the transdermal drug delivery system is applied to a skin site proximate to or in the region of a sports injury, and relieving the pain. The concentrated local anesthetic in the patch penetrates deeply below the skin to the injury site to inhibit pain receptors throughout the damaged body tissue.Type: ApplicationFiled: August 4, 2005Publication date: February 9, 2006Inventor: R.

Patent number: 6519815Abstract: A band clamp for pipe joints is disclosed comprising a band with confronting sidewalls when wrapped around pipes to be coupled. The clamping mechanism includes a pair of force bars outboard of the sidewalls and a spline with concave surfaces on opposite sides, the spline being disposed between the end flanges. A bolt extends through bolt holes and draws the flanges against the spline to stretch the band around the pipes when the bolt is tightened against the force bars. The sidewalls have lateral flanges which overhang the spline to arrest movement of the sidewalls relative to the spline to obtain alignment of the bolt holes when the clamp is tightened. In some embodiments, the band is folded back on itself to form a double thickness which extends from the upper end of each sidewall to a point beyond the lower end of the sidewall and provides an inverted flap sandwiched between the clamp band and the pipe. The inverted flap may be secured to the band by mechanical interlock between the layers.Type: GrantFiled: August 3, 2001Date of Patent: February 18, 2003Assignee: BKS Company, LLCInventors: Thomas R. Cassel, Michael E. Amedure

Patent number: 4990701Abstract: A process for halogen exchange fluorination by contacting a halocarbon having a replaceable halogen other than fluorine with KF.nHF wherein n is 0.5-3 to provide a fluorinated hydrocarbon having at least one more fluorine than the starting halocarbon and, optionally, regenerating the KF.nHF with additional HF, or in a continuous process, with excess HF in the feed.Type: GrantFiled: March 20, 1990Date of Patent: February 5, 1991Assignee: E. I. DuPont de Nemours and CompanyInventors: Wendel R. Cassel, Richard E. Fernandez, Frederick W. Mader

Patent number: 4660862Abstract: A pipe coupling for improved pull-apart strength of pipe lap joints is disclosed. A clamping band is applied to the outside pipe around the overlap region of the pipes. An attachment is applied around the inside pipe and the two bands are connected together by a linkage extending alongside the pipes. Preferably, a sealing structure is provided on the outer pipe in the overlap region such that sealing engagement between the outside and inside pipes is obtained when the clamping band is tightened. When the pipes are subjected to pull-apart forces, the linkage resists slippage or pull-apart motion. If there is slippage, more will occur on the side opposite the linkage and an oblique relationship of the pipes results. This produces a binding action between the pipes with increased frictional resistance to the pull-apart forces.Type: GrantFiled: April 2, 1985Date of Patent: April 28, 1987Assignee: BKS CompanyInventors: Thomas R. Cassel, Scott T. Cassel

Patent number: 4629226Abstract: A pipe lap joint is disclosed with an improved sealing zone structure in the overlap region of the pipe. The sealing zone comprises a pair of end-to-end intersecting slots which are covered by a clamping band and which allow the sealing zone of the pipe to be collapsed against the inner pipe when the clamping band is tightened. The outboard slot extends inwardly from the end of the pipe and terminates in a transverse end wall within the overlap region. The inboard slot is circumferentially offset from the outboard slot and extends inwardly from an outer end wall thereof. The adjacent sidewalls of the slots are in substantial alignment with each other and the end walls are also in substantial alignment with each other whereby the end walls of the slots are disposed in edge-to-edge engagement with each other when the overlap region of the outer pipe is collapsed into close fitting engagement with the inner pipe.Type: GrantFiled: April 16, 1985Date of Patent: December 16, 1986Assignee: BKS CompanyInventors: Thomas R.

Patent number: 4623164Abstract: A band clamp is disclosed for clamping a stabilizer bar to a cross-beam rear axle in a front wheel drive vehicle. A preformed band has a sleeve portion which conforms to the inverted V-shape axle and it has a channel portion with opposed sidewalls extending from contiguous sides of the clamp at one corner. A spline is disposed between the sidewalls and has a concave surface opposite a shaped washer on the outside of one of the sidewalls. A bolt extends through the sidewalls, the spline and the shaped washer and a nut on the bolt is tightened to draw the sidewalls into engagement with the spline to stretch the sleeve portion around the axle.Type: GrantFiled: December 11, 1984Date of Patent: November 18, 1986Assignee: BKS CompanyInventors: Thomas R. Cassel, Scott T. Cassel

Patent number: 4312526Abstract: A pipe coupling is disclosed which comprises an open sleeve which is stretched around the pipes. The open sleeve comprises a roundish sector and a channel-shaped sector comprising a pair of sidewalls extending outwardly from the roundish sector. Force applying means are connected with the sidewalls to draw the sidewalls together and retaining means on the sidewalls are trapped by the force applying means so that the roundish portion of the sleeve is stretched over the pipes.Type: GrantFiled: June 23, 1980Date of Patent: January 26, 1982Inventor: Thomas R. Cassel

Patent number: 4261600Abstract: A coupling for a pipe lap joint is disclosed in which a sleeve has a larger diameter at one end and a smaller diameter at the other end with means for stretching the sleeve around the pipes. The sleeve has a radially projecting channel-shaped sector and force applying means engages the sector to stretch the sleeve around the pipes. The channel-shape sector is uniform in cross section along the length of the sleeve and the larger end of the sleeve is axially offset from the smaller end. An improved method for making the pipe coupling is disclosed in which a sleeve blank is disposed in an external die and stretched outwardly by an expanding mandrel.Type: GrantFiled: December 11, 1978Date of Patent: April 14, 1981Inventor: Thomas R. Cassel

Patent number: 4056273Abstract: A coupling of the disclosure connects and seals inner and outer pipes having an interfitted lap joint by the provision of a coupling band that is stretched about the joint in a clamping relationship over the outer pipe end and a seal ring engaged with the inner pipe. A roundish sleeve portion of the band is stretched by deformation of a radially projecting channel portion thereof which receives a pair of axially spaced reaction members in respective axial alignment with the seal ring and the outer pipe end. A clamping device of the coupling includes tightening members on opposite sides of the band channel portion and cooperable nut and bolt sets that move the tightening members toward each other to deform the band channel portion against the reaction members and thereby stretch the sleeve portion over the joint. A strip of sealing material is bonded to each reaction member and engaged with the outer pipe end and the seal ring.Type: GrantFiled: December 8, 1976Date of Patent: November 1, 1977Inventor: Thomas R.

Patent number: 3977800Abstract: This invention relates to a connector for structural members such as tubes, several of which are brought together at a corner zone or the like. The connector is formed as an extrusion including a body portion from which fastening formations, in the nature of bifurcations, extend in each of three directions. Where the fastening formations extend all in the same general plane the connector may be extruded in one piece but where one or more fastening formations extend in different planes to others, the connector is extruded in two or more parts, one part including the body and two or more fastening formations extending in one plane and another part comprising a further fastening formation which is secured to the body so as to extend therefrom in the different plane.Type: GrantFiled: November 26, 1974Date of Patent: August 31, 1976Inventor: Joe R. Cassel
