Abstract: An integrated exterior inlet/exhaust port for providing two air channels through a wall while only requiring a single hole through the wall.

Abstract: This invention relates to endless tracks and systems used to propel tracked vehicles [i.e., vehicles which use endless tracks rather than tires to contact the terrain over which they are driven, e.g., tractors, tanks, bulldozers, etc.] and, more particularly, to an improved split wheel design and installation process therefore. The track is made from a polymer adapted to travel over a drive sprocket, a plurality of guide wheels and a tension wheel. A new step by step methodology allows the endless track to be installed and used more efficiently when the tension wheel or the drive sprocket is replaced by a split wheel.

Abstract: A compound selected from the group consisting of a compound of formula I a compound of formula II and when the compound of formula I and II comprises an amino group pharmaceutically acceptable ammonium salts thereof, wherein R1, R2, Cx, n, R3, R4, R5, Y are as defined in the specification.

Abstract: The present invention provides HIV aspartyl protease inhibitors of the formula; and when the compound of formula I comprises an amino group, pharmaceutically acceptable ammonium salts thereof, wherein n is 3 or 4, wherein R1 may be, for example, iso-butyl, wherein X and Y, same or different, may be, for example, NH2 and F, and wherein R2 and R3 are as defined herein.

Abstract: An apparatus and method to auto-splice tapes in a tape dispensing machine where a continuous supply of tape is required. When a new roll of tape needs to be provided, a splicing apparatus or technique must permit to securely and efficiently make the connection between the first roll of tape and the new tape. The apparatus and method provide an open clip which engages one extremity of a running tape and one extremity of a stationary stand-by tape.

Abstract: A compound selected from the group consisting of a compound of formula I a compound of formula II and when the compound of formula I and II comprises an amino group pharmaceutically acceptable ammonium salts thereof, wherein R1, R2, Cx, n, R3, R4, R5, Y are as defined in the specification.

Abstract: A process for producing a thermoelectric material based on two or more elements selected in the group constituted by Bi, Sb, Te and Se, which process comprises: i. an alloying step wherein determined amounts of the elements Bi, Sb, Te or Se are mixed until an homogenous powdered alloy is obtained; ii. an extrusion step of the powdered homogenous alloy obtained in the preceding step. The elements Bi, Sb, Te or Se being preferably mechanically mixed in an homogenous powdered alloy. The thermoelectric material, which are obtainable by this process, exhibits improved thermoelectric and mechanical properties and are therefore suitable, for example, as cooler, as temperature stabilizer in a electronic device or as power generator.

Abstract: The present invention provides HIV aspartyl protease inhibitors of the formula: and when the compound of formula I comprises an amino group, pharmaceutically acceptable ammonium salts thereof, wherein n is 3 or 4, Y is O, S, NH or N—CN, wherein Cx may be, for example COOH, or CH2OH, wherein R1 is selected from the group consisting of a benzenesulfonyl group of formula II as defined herein, wherein R2 may be, for example, iso-butyl, or 3-methylbutyl, and wherein R3 and R4 are as defined herein.
