Abstract: This invention relates to the guide lugs of reinforced elastomeric endless traction bands, which are used on heavy vehicles like defence vehicles. More specifically, the invention relates to guide lugs which are partly nested into each other around the curved portion of the traction band in order to minimize de-tracking occurrences.

Abstract: This invention relates to an endless traction band that is used to propel tracked vehicles and, more particularly, to an improved traction band made from a polymer adapted to travel over a drive sprocket, a plurality of guide wheels and a tension wheel. The inner surface of the endless traction band includes a different lug configuration which allows for the endless traction band to be installed more efficiently on a tracked vehicle.

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: The endless track is made of a reinforced rubber material with longitudinally spaced and transversely disposed ridges or lugs. It is particularly well-adapted for recreational snowmobiles having a single track. The ground-engaging side of the track features a tread pattern that is repeated uniformly or not over the entire length of the track. The tread pattern comprises a plurality of projecting traction lugs each having an upper edge. The internal side of the track features a plurality of protuberances called drive lugs which engage in the sprockets. These sprockets are driven by the snowmobile engine and transmit its power to the endless track. The braking power is also transmitted by the sprockets to the track. It is characterized in that the drive lugs have a pitch distance half of the pitch distance of the tread pattern therefore doubling the number of lugs engaged in the sprocket. Such tracks reduce noise and rolling resistance.

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 winch assembly for the displacement of a person between a first vertical position and a second vertical position comprising: a winch for displacing a person in a harness between said first and second vertical positions; a first winch attachment means for realizably engaging said harness, said first winch attachment means being attached to said winch for the displacement of a person between said first and second vertical positions; and a second winch attachment means for realizably attaching the winch to an overhead support, the improvement wherein said first attachment means comprises two opposed support arms and displacement means associated with each said support arms whereby at least part of each arms is displaceable between a working extended position for engaging said harness and a non-working retracted position. The winch has a reduced or more compact aspect during non-working periods as well as in the case of a moving of the winch assembly during non-working periods.

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 endless track is made of a reinforced rubber material with longitudinally spaced and transversely disposed ridges or lugs. It is particularly well-adapted for recreational snowmobiles having a single track. The track is characterized in that the rubber material of the central portion of the body has a hardness of between 75 and 90 duro A while the rubber material of the opposite band portions of the body has a hardness between 55 and 75 duro A. Such track facilitates the steering capabilities of a snowmobile, particularly when the snowmobile is traveling on hard and abrasive surfaces. It also improves the durability of the track.

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.

Abstract: A compound of formula I′ and pharmaceutically acceptable derivatives thereof including, for example, where applicable or appropriate pharmaceutically acceptable salts thereof. Ar and Ar′ are aromatic or aryl type groups. The compounds have HIV integrase inhibitory properties. Ar, Ar′ and W may be as defined in the specification.
