Abstract: A stationary phase for a liquid chromatograph and process for making is provided. The stationary phase material may have a modified base substrate and a fluorinated carboxylic acid covalently bonded thereto through an amide or ester bond. The stationary phase may have a substantially consistent shape selectivity characteristic with an ?TBN/BaP of less than 1 within a temperature range of at least 10-70° C. Advantageously, a fluorinated stationary phase has a shape selectivity characteristic exhibited with an ?TBN/BaP of less than 1 with a mobile phase having up to at least 30% water. A process for making the stationary involves mixing a substrate material or fluorinated carboxylic acid with a reactive alkylsilane linker and at least one organic solvent to form a first solution. The other of the substrate material or fluorinated carboxylic acid is then added to the first solution, or to a product separated from the first solution, to form a second solution.

Abstract: A high efficiency fluid filter arrangement wherein a combined layer of scrim and filter media applications is of empirically relatively estimated weight size and depth with intermediate pleat spacing so as to arrive at a combined filtration capability value in keeping with selected approved test standards.

Abstract: The invention relates to a reconstituted smoking material which comprises a non-polyol aerosol generator, tobacco (optional), binder (optional) and inorganic filler. A further polyol aerosol generator may also be contained in the smoking material. There is also provided a smoking article containing such material in a conventional arrangement or with a core axially disposed within an annulus. A further aspect of the invention is the provision of a polyol or non-polyol aerosol generated disposed in the filter element of a smoking article, which may contain the inventive smoking material. The aerosol material on the filter is eluted into the aerosol of the smoke on burning of the smoking article.

Abstract: An ankle brace with a single piece hinge, interchangeable stirrup and pivot legs and an adjustable strap position fastener for protecting and exercising an injured ankle or for use with other orthopedic devices is described herein. The ankle brace pivots around a singular pivoting point on both the interior and the exterior portion of the lateral support members of the stirrup portion of the brace. The pivoting hinge of the ankle brace does not require use of metal rivets or bulky hinges and may be easily connected together by the wearer or manufacturer. The separable hinge design of the ankle brace described herein is sufficiently strong to provide substantial lateral support while allowing for forward and backward flexing of the ankle. The design also allows for interchanging the stirrup portion of the brace with different inner and outer pivot legs.
