Granted: 1997-09-09
Abstract: In an antenna supervising apparatus for supplying a multiplexed signal comprised of a plurality of carrier wave  signals  respectively outputted  from a plurality of transmitters through a transmission line to an antenna, a directional  coupler  detects  progressive  signals  of  the multiplexed signal to the antenna and the reflected signals thereof   from  the  antenna,   and  a  band-pass   filter respectively  filters  the  progressive  signal  and  the reflected  signal  of  one  carrier wave signal preselected among those of the detected multiplexed signal.  Further, a detector  respectively  detects  the  filtered  progressive signal and the filtered reflected signal of the one carrier wave  signal,  and  a  micro  processing  unit  calculates  a standing wave ratio with respect to the preselected one carrier wave signal based on the detected signals.

Title: Tandem fuel pump assembly for internal combustion engine
Inventor: GRINSTEINER JAMES J
IPC: F04B23/08
Filed: 1991-09-30
Granted: 1999-07-20
Abstract: A tandem fuel  pump assembly  for  internal  combustion engines includes a housing having a fixed spring retainer mounted thereinside which supports a diaphragm pump biassing spring thereabove to force a diaphragm defining the movable lower wall of a first pumping chamber to reduce the volume thereof and eject fuel  from an outlet thereof preferably through  a  fuel  filter  to  the inlet  of  a  second piston pumping chamber. A second biassing spring supported below the spring retainer forces a pumping piston downwardly to reduce the volume of the second pumping chamber and thereby eject fuel therefrom to an engine fuel rail for injection into the engine therefrom.  The  diaphragm and piston are mechanically connected by a pump stem through a lost motion connection to accommodate differing pumping strokes of the two pumps, so that a single tappet actuated by the engine camshaft mechanically raises the piston to cause movement thereof to fill the second piston pump chamber while the biassing  spring  of  the  piston  pump pulls  the  diaphragm through the stem against the action of its biasing spring to fill  the first chamber during the pumping  stroke of  the piston pump.

Title: Rf power amplifier
Inventor: FUJITA NORIYUKI
IPC: H03F3/20
Filed: 1992-05-29
Granted: 1996-07-02
Abstract: A radio frequency (RF) amplifier for amplifying an RF signal with a high power efficiency and with a minimum of signal distortions by using a GaAs field effect transistor (FET).  An idling current for class "A" amplification is set in the FET.  An output low pass filter is connected to the drain of the FET and provided with an impedance higher than a high gain impedance, so that the FET and a load may be matched in power during high RF signal operation, i.e., the dynamic impedance of the FET and the impedance of the load may be matched.          A drain bias to the FET is turned on and turned off in synchronism with the ON/OFF of the input RF signal.          The amplifier, therefore, not only performs class "A" amplification with a minimum of signal distortions but also further saves power since it is turned off in the absence of a signal, thereby achieving a higher power efficiency.

Title: Vacuum cleaner
Inventor: PURI KRISHAN KUMAR
IPC: A47L9/14
Filed: 1993-04-30
Granted: 1997-05-06
Abstract: A vacuum cleaner having a body with an inlet opening for dust laden air and an outlet.  An impeller is located between the inlet and the outlet.  A chamber within the body having at least one wall receives a perforate dust receptacle.  The chamber is located up-stream of the impeller.  An inlet passageway extends from the inlet opening into the chamber.  This passageway is directed so that when a perforate dust receptacle is in position in the chamber, the inlet passage has an outlet directed at a wall of the dust receptacle.  Dust laden air entering the receptacle is filtered to remove dust.  The dust laden air, forced against the wall by the impeller, acts to keep the wall free of dust accumulation.

Abstract: Un absorbant de NOx (18) est disposé dans le trajet des gaz d'échappement dans le moteur à combustion interne, et les gaz d'échappement sont adaptés pour s'écouler constamment à travers ledit absorbant (18) lors du fonctionnement du moteur. L'absorbant de NOx absorbe le NOx lorsqu'un rapport air-carburant de gaz d'échappemetn circulant dans ledit absorbant (18) est pauvre et, lorsqu'un rapport air-carburant de gaz d'échappement devient égal au rapport air-carburant théorique ou riche, il évacue le NOx qu'il a absorbé. Sur pratiquement la totalité de la plage de fonctionnement du moteur, un mélange gazeux pauvre est brûlé dans la chambre de combustion (3) et le NOx produit à ce moment-là est absorbé par ledit absorbant (18). Un rapport air-carburant de gaz d'échappement circulant dans l'absorbant de NOx (18) est périodiquement égalisé avec le rapport théorique ou riche, et le NOx ayant été absorbé par l'absorbant (18) est évacué et réduit en même temps.

Title: Recycled polyethylene construction product and method of manufacture
Inventor: BERTRAM EDWARD F
IPC: C08L23/04
Filed: 1993-07-29
Granted: 2006-10-03
Abstract: A cast recycled polyethylene product, optionally containing fibre reinforcement such as scrap polyester, contains oil as a compatibilizer. Typically the oil is derived from recycled containers. The product is made by comminuting containers, adjusting the oil content to the desired range, adding fibre reinforcement if desired, and heating the mix to a temperature sufficient for the polyethylene to commingle with the reinforcement if present, but insufficient to damage the fibers.      Typical cast products include guard rail posts, fence posts, highway median dividers, parking curbs, and the like. These products have the advantage of not being subject to weather damage and loss of structural strength, as is the case with timber and concrete.

Granted: 1999-10-05
Abstract: Defects such as corrosion located on the exterior of a component such as a metal pipe, tank, vessel or support structure which is insulated by a coating or cover, are detected by a low frequency eddy current (LOFEC) system. A magnetizing yoke in the shape of an inverted U is placed on the cover insulating a metal component. An excitation coil is wrapped around the magnetizing yoke for carrying an altering current in order to produce an alternating magnetic field by the magnetized yoke. The alternating magnetic field produced by the magnetized yoke induces an eddy current which runs through the metal component between the legs of the yoke. A pair of magnetic flux sensors are used in differential connection beneath one or more excitation coils which can be articulated to conform to varying pipe diameter. In addition, an absolute signal response can be obtained from one of the receiver coils.      This arrangement allows for the reduction and minimizing of unwanted and extraneous signal responses caused by variations in the component structure while the yoke is scanned about the cover and a positive separation of loss of metal signals (CUI) from artifact signals.      Defects located on the surface of pipes or tanks covered with marine growth can be detected using the DPEC probe with either a signal magnetic flux sensor located beneath the excitation coil or a plurality of magnetic flux sensors differentially connected.

Abstract: A dynamical system analyser (10) incorporates a computer (22) to perform a singular value decom-position of a time series of signals from a nonlinear (possibly chaotic) dynamical system (14). Relatively low-noise singular vectors from the decomposition are loaded into a fi-nite impulse response filter (34).      The time series is formed into Tak-ens' vectors each of which is pro-jected onto each of the singular vec-tors by the filter (34). Each Takens' vector thereby provides the co-ordi-nates of a respective point on a tra-jectory of the system (14) in a phase space. A heuristic processor (44) is used to transform delayed co-ordi-nates by QR decomposition and least squares fitting so that they are fitted to non-delayed co-ordinates.      The heuristic processor (44) gen-erates a mathematical model to implement this transformation, which predicts future system states on the basis of respective current states. A trial system is em-ployed to generate like co-ordinates for transformation in the heuristic processor (44). This produces estimates of the trial sys-tem's future states predicted from the comparison system's model.  Alternatively, divergences between such estimates and actual behaviour may be obtained. As a further alternative, mathematical models derived by the analyser (10) from different dynamical systems may be compared.
