  • Patent number: 6664249
    Abstract: Compounds according to general formula (1), and pharmaceutically acceptable salts thereof, wherein V is a covalent bond or NH, X is selected from CH2, O and N-alkyl, Z is either S or —CH═CH—, R1 and R2 are independently selected from H, F, Cl, Br and alkyl, R3 is selected from OH, O-alkyl and NR4R5, R4 and R5 are each independently H or alkyl, or together are —(CH2)q—, p is 0, 1, 2, 3 or 4, and q is 4 or 5, are new. They are agonists at the asopressin V2 receptor and are useful as antidiuretics and pro-coagulants.

  • Publication number: 20030216450
    Abstract: Compounds according to general formula (1), wherein R1 is H or CN, X1 is S, O, SO2 or CH2, X2 is O, S or CH2, X3 is NR5 or a carbonyl or thiocarbonyl group and R4 is R6R7N, R8(CH2)qOC(═O), R8(CH2)qOC(═S), R6R7NC(═O), R6R7NC(═S); R8(CH2)qC(═O), R8(CH2)qC(═S) or R8(CH2)qSO2, m is 1-3 and n is 0-4 are new. The compounds of the invention are inhibitors of dipeptidyl peptidase IV. Pharmaceutical compositions of the compounds of the invention, or pharmaceutically acceptable salts thereof, are useful in the treatment of,inter alia, type 2 diabetes.

  • Patent number: 6632999
    Abstract: A floor grommet for use in building and office structures supplied with air conditioning via under floor plenum. Directed flow of conditioned air is optimized by limiting the escape of air from the plenum into the space above the floor by leakage through floor openings provided for power cables, data cables and the like. Specialized floor grommets installed in the cable openings are comprised of a surrounding frame mounting sealing elements comprised of thin, flexible elements which are anchored at one end in the grommet frame and extend toward the center of the opening, from each side, to effectively close the opening against significant flow of conditioned air from the plenum below. Cables passing through the grommet opening cause minimal deflection of the flexible elements to limit the escape of conditioned air. Preferably, the resilient, flexible elements are filamentary in nature.

  • Publication number: 20030131227
    Abstract: System and method for configuring a second system in a split bridge distributed environment. A host computer system (host) includes a memory operable to store host driver software (drivers) and a CPU operable to execute the drivers. A serial bus couples the host to the second system. The host saves configuration information for the second system. The second system receives user input requesting a power down condition. The drivers enters a quiescent state, generating an indication of a power down condition. The user powers down and reconfigures the second system. The host detects a link down condition between the host and the second system, and monitors a link status between the host and second system. The user powers up the second system. The host detects a link up condition, restores second system configuration, and performs a discovery process on the second system.

  • Publication number: 20030087892
    Abstract: This invention provides novel compounds according to general formula (1) wherein A is a bicyclic or tricyclic azepine derivative, V1 and V2 are both H, OMe or F, or one of V1 and V2 is Br, Cl, F, OH, OMe, OBn, OPh, O-acyl, N3, NH2, NHBn or NH-acyl and the other is H, or V1 and V2 together are ═O, —O(CH2)pO— or —S(CH2)pS—; W1 is either O or S; X1 and X2 are both H, or together are ═O or ═S; Y is OR5 or NR6R7; R1, R2, R3 and R4 are independently selected from H, lower alkyl, lower alkyloxy, F, Cl and Br; R5 is selected from H and lower alkyl; R6 and R7 are independently selected from H and lower alkyl, or together are —(CH2)n; n=3, 4, 5, 6; and p is 2 or 3. The compounds are agonists at the vasopressin V2 receptor and are useful as antidiuretics and procoagulants.

  • Patent number: 5432493
    Abstract: A transformer arrangement is provided which has a primary and at least one secondary winding coupled via a movable armature which is outside of the windings. A second transformer can be provided which has primary and secondary windings coaxial with and surrounding the corresponding windings of the first transformer. The armature is tubular and slidable in the radial clearance defined between the windings of the first transformer and the windings of the second transformer.

  • Patent number: 4951548
    Abstract: An apparatus for supplying belt-linked ammunition to a gun. Belt-linked ammunition is supplied to a gun by an apparatus comprising a plurality of standard rectilinear ammunition boxes in which the ammunition belts are arranged so that both of their ends are accessible. The boxes are secured beneath an arcuate supporting guide which traverses with the gun and which has openings through which both ends of each belt can pass, for leading in respective directions towards an adjacent box or towards the gun. The boxes are arranged to extend tangentially of the guide so that the axes of rounds of ammunition within the guide are directed radially of the axis of curvature thereof.
