Abstract: A system (10) for capturing HAPs/VOCs from an existing or planned air stream and destroying the contaminants in the air stream by microbial degradation is disclosed. In general, the system is composed of a reservoir (14) with a filter structure (12) positioned above it. The filter structure contains a capture or filtration media (18) through which contaminated air or vapors must pass. HAPs/VOCs in the air or vapors are filtered out and absorbed by the capture media. The reservoir contains a tank water bath (WT) that is inoculated with microorganisms that are selected to degrade the hazardous materials or pollutants removed by the capture media. Sprinkler heads (24) above the filter structure spray the filter structure with a sprayed water bath (WS) also inoculated with the microorganisms, whereby contaminants caught in the filter structure are leached out and bioremediated.

Title: Novel leukotriene receptor antagonists and their uses
Inventor: CHURCH TIMOTHY J
IPC: C07C213/00
Filed: 1999-06-08
Abstract: This invention relates to novel multibinding compounds that bind to leukotriene receptors and inhibit their activity. In particular, cysteinal leukotriene receptor antagonists and, most particularly leukotriene D4 receptor antagonist compounds are disclosed. The compounds of this invention comprise 2-10 leukotriene receptor ligands covalently connected by a linker or linkers, wherein the ligands in their monovalent (i.e., unlinked) state bind to leukotriene receptors. The manner of linking the ligands together is such that the multibinding agents thus formed demonstrate an increased biologic and/or therapeutic effect as compared to the same number of unlinked ligands made available for binding to the leukotriene receptors. The invention also relates to methods of using such compounds and to methods of preparing them. The compounds of this invention are particularly useful for treating diseases and conditions of mammals that are mediated by leukotriene receptors. Accordingly, this invention also relates to pharmaceutical compositions comprising a pharmaceutically acceptable excipient and an effective amount of a compound of this invention.

Inventor: YOUNG GLEN C
IPC: H02P6/08
Filed: 2000-02-04
Abstract: A motor system including a gate drive for driving a motor. An inverter bridge circuit selectively connects power supply link rails to a winding of the motor for energizing the winding with a motoring current. The bridge circuit has upper and lower power switches connected between the winding and the upper and lower power supply link rails, respectively. Each lower switch corresponds to one of the upper switches on the same side of the winding as the lower switch to define an arm of the bridge circuit. A control circuit generates a motor controlled signal to control the switches. A drive circuit drives the upper switches in response to the state of the corresponding lower switches, which are responsive to the motor control signal. The drive circuit includes a voltage gain element connected to each arm of the bridge circuit that is responsive to current in the respective lower switch for maintaining the corresponding upper switch in its nonconducting state. In a three phase embodiment, a quadrature axis winding corresponds to each phase winding. Each of the quadrature axis windings is in magnetic coupling relation with the rotatable assembly and positioned for generating an output signal representative of angular position of the rotatable assembly. The control circuit generates the motor control signal to control commutation of the phase windings in response to the output signals of the quadrature axis windings.

Title: Reporter gene system for use in cell-based assessment of inhibitors of the hepatitis c virus protease
Inventor: POTTS KAREN ELIZABETH
IPC: C12Q1/02
Filed: 1999-08-02
Abstract: A cell-based assay system in which the detection of the reporter gene activity, or secreted alkaline phosphatase (SEAP), is dependent upon the protease activity of the Hepatitis C virus NS3 gene product. This system can be used to assess the activity of candidate protease inhibitors in a mammalian cell-based assay system. The assay system is simpler than previously described assays due to the use of SEAP which allows the reporter gene activity to be quantified by measuring the amount of secreted gene product in the cell media by monitoring the conversion of luminescent or colorimetric alkaline phosphatase substrate.

Abstract: A high-speed binder application device for wrapping binder material about a bundle of buffer tubes that encase a plurality of optical fibers includes a pair of opposite facing binder heads mounted on a pair of hollow shafts, each shaft being driven in rotation by a concentric drive motor mounted about the shaft. Each binder head includes a light-weight synthetic guide drum that dispenses binder material off a reel and onto the bundle of buffer tubes as it is advanced through the hollow shafts. The concentric mounting of the drive motors on the shafts eliminates shaft bending loads from drive belt tension and reduces vibrations at higher rotational speeds relative to belt-driven systems. The light weight and high strength of the synthetic guide drums allows the drums to be rotated at speeds in excess of 4000 RPM.
