A capacitor (54, 56) couples each of the input signal conductor distal ends (48d, 48c) to an adjacent ground conductor (36, 38). The signal conductors (48b, 48c) and capacitors (54, 56) provide a selected impedance at a selected frequency. An output coplanar waveguide (28) includes, for each drain terminal (72) an output signal conductor (88) having an end (82a) in the connection region (32) that is electrically connected to the flip mounted FET chip (26). This waveguide (28) also has a length selected to provide desired impedance matching and may also have other means of impedance matching.

Abstract: A microwave filter has at least two resonators, with at least two degenerated wave types resonance-capable in one resonator. The resonators are in operative connection with one another so that possible couplings of the degenerated wave types are only overcouplings and these overcouplings are located outside the resonator in which the two degenerated wave types are resonance-capable. As a result, the microwave filter has higher quality, improved selection properties and optimal polarization adapation.

Granted: 2000-09-12
Abstract: A system for detecting metal targets located in a background environment such as the ground evaluates metal targets by processing components of signals at two or more different frequencies. A component of the received signal induced by the ground can be eliminated by subtracting signal components measured at two different frequencies. The received signal can be processed to account for changes in the background response with frequency. The type of an unknown target can be identified by processing background excluded components to produce data characterizing the target type.

Title: Liquid container valve structures for use with service-line connectors
Inventor: SPALDING LAMAR
IPC: B67D3/04
Filed: 1995-09-12
Granted: 2007-01-30
Abstract: A spout fitment (21) attached to a liquid filled bag (B) having a slidable dispensing valve member (217) to receive a line connector (70) for establishing a fluid path from an interior of the bag (B), through a valve element (84) in the line connector (70) and into a service line. Although the valve member (217) is slid into the bag when the line connector (70) is inserted therein, the sliding motion does not form the valve action. The bag seal is established by a valve element (223) within the valve member (217) that is resiliently biased to close an opening (215) therein. The valve member (217) thus need not be slid in the fitment (21) when the line connector (70) is removed from the valve member (217), thereby making it easier to remove and reinsert the line connector (70). Insertion of the line connector (70) within the valve member (217) causes their respective valve elements to engage each other to open and form the fluid flow path.

Abstract: A steering wheel "after-market" overlay, having a unitary, integral, relatively stiff, thin-walled construction, is adapted to be adhesively applied to and closely conform to the surface of the upper portion of an original equipment steering wheel. The overlay covers not only the upper portion of the steering wheel grip but also the upper portions of the steering wheel spokes up to the center pad of the steering wheel. The portion of the overlay covering each spoke has an radially inner terminus including a flange that is adapted to extend into the small space that typically exists between the inner end surface of the spoke and the side peripheral surface of the center pad. By also covering the upper portions of the spokes, not only is the appearance of the overlaid steering wheel enhanced, but the bonded surface area is substantially increased thereby assuring the long term positional stability and peel resistance of the overlay.

Abstract: A centrifugal compressor having an impeller wheel mounted for rotation about a central axis and a diffuser for emptying compressed fluid into a collector chamber. A plenum chamber is located behind the impeller shroud and series of deswirl passages are located about the impeller for placing the collector chamber in fluid flow communication with the plenum chamber. A series of channel flow passages are further arranged to inject compressor fluid in the plenum chamber into the exit flow leaving the tips of impeller blades under controlled conditions so that the injected fluid enters the exit flow smoothly and with little loss of energy. An adjustable control means regulates the flow through the deswirl passages to keep the total flow moving through the diffuser relatively constant under varying load conditions.
