Title: Bottom feed - updraft gasification system
Inventor: TAYLOR LELAND T
IPC: C10J3/02
Filed: 1994-03-17
Abstract: A gasification system for solid wastes having a thermal reactor (20) and a mechanical gas cleaner (70), an indirect heat exchange cooler (120), and an electrostatic precipitator (130) for cleaning and cooling the produced gas. Feed material is continuously fed to the central section of the thermal reactor (20) above an air introduction manifold (38) and nozzles (40) in an upward direction, forming a stratified charge. As feed material moves upward and outward from the reactor center, it is reduced to ash. An agitator (54) assures contact between the hot particulate product and hot gases resulting in gasification of the feed material and net movement to the sidewall of the thermal reactor (20) forming an ash. The air introduction nozzles (40) serve as a grate. Ash descends along the sidewall to the reactor base for removal.

Title: Pneumatic tire having improved wet traction
Inventor: LANDERS SAMUEL PATRICK
IPC: B60C11/12
Filed: 1995-12-12
Abstract: A pneumatic tire having improved wet traction has an annular aquachannel center groove and curved lateral grooves which direct water from the footprint to the shoulder area of the tire to help prevent hydroplaning.  The lugs contain sipes which change direction within the lug and tie bars in the sipes near each point where the sipes change direction. Siping, and the positioning of tie bars, provide means for minimizing the difference of the principle direction of lug stiffness between individual lugs. Also, a tire of the invention has 4 pitch ratios which are distributed around the tire so that extra large pitches are not located next to small pitches.

Title: Interrupted-flow assay device
Inventor: CHANDLER HOWARD M
IPC: B01L3/00
Filed: 1994-12-06
Abstract: The present invention provides chromatographic assay devices that can perform multiple assays simultaneously in the same test strip, as well as methods for their use. One of the assays can be an immunological assay to detect an antigen, such as human chorionic gonadotropin, while another assay can be a serological assay to detect an antibody, such as antirubella antibody.  An assay device according to the present invention can comprise: (1) a first opposable component (12) including at least one chromatographic  medium (24) having a specific binding partner to the first analyte (34) and a specific binding partner to the second analyte immobilized thereto in separate, discrete, non-overlapping zones (36); and (2) a second opposable component (14) including an absorber (50).  The first and second opposable components are configured such that bringing the first and second opposable components into opposition causes the absorber to come into operable contact with at least one chromatographic medium so that the zone containing the specific binding partner to the first analyte is functionally divided from the zone containing the specific binding partner to the second analyte so that both analytes can be detected.
Patent CA-2173026-A1 (CA)
Inventor: TANIGAWA YOSHIHIRO
IPC: H01R24/62
Filed: 1996-03-29
Abstract: A modular jack telephone-type connector has a housing which is associated with a carrier on which metal conductors are mounted on a top surface thereof. A wire positioning fixture, which has wire openings for inserting electrical wires and a cavity for receiving terminals of the conductors, is supported in a hole on the top carrier surface allowing the fixture to move vertically in the hole with respect to the carrier. Vertical fins, which are mounted on the carrier, mate with vertical grooves, which are provided on an opposite side of the wire openings of the fixture, for additional secure positioning. A lever, which is pivotable on the housing, rotates toward or away from the carrier, and is coupled to the fixture via an interlock mechanism in order to transmit a rotational lever motion to the vertical fixture motion. As the lever rotates toward the carrier and pushes the fixture downward, wires inserted into the fixture precisely meet terminals, which extend through the cavity of the fixture. Slicers, provided on the terminals, remove the insulation from the wires ensuring good electrical contact between the wires and the terminals without using special termination tools.

Title: Data modulation arrangement for selectively distributing data
Inventor: WARWICK ALASTAIR ANTHONY
IPC: H04N7/16
Filed: 1994-12-07
Abstract: A cable television distribution arrangement is supplied via optical fibers with additional digital signals which are delivered to customers via coaxial drop cables (20) modulated at frequencies above those of the conventional analog television channels. A reduction in the required number of modulators is achieved, while delivering individually selected signals to individual customers, by supplying digital signals for a group of customers to a first modulator (72) and a pseudo data signal to a second modulator (84), and selecting (78) between the outputs of the two modulators individually for each customer in the group. Switching between the outputs of the modulators is carried out during overhead information (O/H) which is additionally supplied commonly to both modulators.

Title: System and method for storing and displaying ultrasound images
Inventor: MCDONALD OMID
IPC: G06F19/00
Filed: 1996-06-11
Abstract: A system for recording and displaying ultrasound images is disclosed. The system includes a database server, an ultrasound image capture station and an ultrasound image review station. The ultrasound images are captured from an analog video signal stream output by an ultrasound machine and converted into compressed digital data preferably in MPEG format. The compressed digital data is archived to a compact disc recordable medium for permanent storage. The ultrasound images may be annotated by a sonographer as they are captured. The sonographer selects an annotation icon from a predefined list of icons to highlight points of interest in an ultrasound scan. The system also includes a demographic data module for trackingcaptured ultrasound scans, and a clinical data module for reporting ultrasound findings and diagnoses. The advantages include reduced storage requirements because of the elimination of video tape; more accurate tracking of ultrasound scans; easier review due to perfect still frames, random access, annotated highlights and zoom capability; faster more accurate reporting of findings and diagnosis; and, the ability to share ultrasound images over local and wide area networks.

Inventor: HAYNES BARBARA L
IPC: B32B7/02
Filed: 1994-12-21
Abstract: A semi-rigid, light weight insulation blanket (20) is composed of a skeleton (12) having porous cavities sandwiched between layers of fiber glass (10). The polyimide foam skeleton (12) prevents sagging particularly in crown and upper sidewall areas of an aircraft thereby maintaining a predetermined offset from the skin fuselage reducing corrosion of the primary structure from moisture condensate.  This configuration provides similar acoustic performance with reduced weight.

Title: Impeller plates for rotary cutting units of a crop harvester
Inventor: PRUITT MARTIN E
IPC: A01D34/66
Filed: 1993-04-02
Abstract: A swing-tongue harvester (10) has a hydraulically controlled pulling tongue (30) that can be operated from the tractor seat to change the lateral position of the machine relative to the towing tractor (36), notwithstanding thepresence of a mechanical drive line (90) which extends along the tongue (30) and branches down to a gearbox (116) carried by the header (50) for driving the operating components of the header (50). Telescoping steering linkage (138) between the swing tongue (30) and the gearbox (116) causes the gearbox (116) to swing responsively with the tongue (30) when the tongue is swung to any of its angular positions, thus keeping the input shaft (114) of thegearbox (116) oriented properly toward the driveline (90) along the tongue (30). The connection points for the steering linkage (38) between the tongue (30) and the gearbox (116) are such that a telescoping section (106) of the drive line (90) bridging the tongue (30) and the input shaft (114) of the gearbox (116) has equal angles maintained at its universal joints (104,110) at opposite ends of the telescoping section (106) to reduce unequal loading at those locations. Specifically configured impeller plates (186) associated with the left and right, endmost rotary cutting units (172) on the cutter bed of the header (50) assist in proper delivery of the cut materials rearwardly into the discharge opening (65) of the header (50).
