Title: Microwave diode oscillator
Inventor: LI HSIU Y
IPC: H03B/
Filed: 1987-07-22
Granted: 1991-10-22
Abstract: MICROWAVE DIODE OSCILLATOR                  ABSTRACT OF THE DISCLOSURE The four-diode bridge is positioned within the cavity of a Gunn diode oscillator.  A subharmonic signal is applied to the diode bridge and the diode bridge couples an odd harmonic of the injected signal into the cavity.  The cavity is thus caused to resonate at the odd harmonic of the injected signal.  The injected signal can be changed using a frequency synthesizer in order to provide a microwave oscillator with multiple-channel operation.  The diode bridge provides a feedback signal indicative of the phase of the cavity oscillation. The feedback signal is applied to a varactor which pretunes the Gunn diode oscillator and thereby provides phase-locked control.

Granted: 1991-11-19
Abstract: ABSTRACT            A  relative  position navigation  system and method installed in a first participant for computing  the  relative  position,  in  range  and azimuth, of at least one other participant in the system  without  using  azimuth-sensing  apparatus.          The system includes ranging apparatus for determin-ing the distance between the first participant and the other selected participant for at least three selected points in time.   A processor determines the change in position of the first participant relative to the second participant during the time periods between the first and second,  and second and  third  points  in  time,  and  computes  the "synthetic" (rather than measured) azimuth coordi-nate of the selected other participant relative to the first participant at the third point in time as a function of the distance and change in relative position data obtained by the system.         The method includes the steps of deter-mining the distance between the two participants at three times, determining the change in position of the first participant relative to the second over the resulting two time intervals and computing the non-ambiguous solution for the relative position as a function of the distances and changes in relative position.

Title: Conversion of pyrethroid isomers to more active species
Inventor: AGER JOHN W
IPC: C07C255/57
Filed: 1988-05-24
Granted: 1993-03-16
Abstract: ABSTRACT:     Crystallizable pyrethroid isomers or enantiomer pairs are converted to more pesticidally active isomers by contacting a hydrocarbon slurry of the starting isomers with a base and a catalyst, the catalyst being substantially soluble in the slurry and selected from a quaternary ammonium compound, a quaternary phosphonium compound and a crown ether, agitating the slurry while maintaining a temperature effective for conversion, and recovering the resulting isomers.  The tendency to form benzoin ester by-product is reduced by including in the slurry a weak base, an aldehyde scavenger such as a metabisulfite, and/or a tetraalkyl(C1-C5)ammonium halide catalyst dissolved in an aprotic solvent such as an organic nitrile.  The process typically is effective for enriching cypermethrin, cyfluthrin and (cyano)(3-phen-oxyphenyl)methyl 3-(2,2-dibromoethenyl)-2,2-dimeth-ylcyclopropanecarboxylate in the more active species.

Abstract: The invention relates to a keyboard comprised of two transverse arrays of conductors defining a number of cross-points at each of which a key is positioned.  The depression of a key causes the conductors at the corresponding cross-points to be electrically connected. A scanning device is connected to each of the conductors and adapted during a scanning operation to apply a high or low potential to all the conductors of the two arrays and subsequently sequentially to apply a potential of the opposite type to each conductor of one array and to monitor the potential of the conductors of the other array such that if the potential of a conductor of the other array changes, this indicates that the key at the corresponding cross-point is depressed.  The scanning device is connected directly to each of the conductors of the arrays and the keyboard to each of the conductors of the arrays.  The keyboard is further comprised of at least one indicating device connected to one of the conductors for indicating a condition of the keyboard.

Abstract: In an image sensing apparatus such as a video camera, an evaluating value for exposure control and determination of a gamma correction value is computed in response to a video signal obtained by an image sensing device for each of a plurality of sampling areas set on an image sensed picture.  When an evaluating value exceeding an allowable range with respect to a predetermined reference value is included in the evaluating values, it is determined that an abnormal luminance portion exists in the corresponding sampling area, so that weighting of the evaluating value is decreased, whereby the effect of such an area on exposure adjustment is restrained.  In addition, the picture contrast is computed from the ratio of the maximum value to the minimum value of the evaluating values, whereby the most suitable gamma correction value is determined based on this picture contrast.

Title: Apparatus for exposing the reinforcing bars of reinforced concrete pillars
Inventor: BERCZES ZSOLT
IPC: E04G23/08
Filed: 1989-04-06
Granted: 1993-07-20
Abstract: ABSTRACT OF THE DISCLOSURE         The crushing tools are designed as rocker-like  chisels having cutting edges.  These chisels are pivotably supported at a frame  such to pivot around a horizontal axis.  These chisel-like crushing tools are operated by a piston-cylinder unit  which extends almost vertically and is pivotably mounted to the box-shaped frame.  Accordingly, the apparatus can be designed with a small width.  Furthermore, The rocker-like  design of the crushing tools allows due to the various lengths of the lever arms  an increase of the forces without necessitating an exchanging of the piston-cylinder units. Furthermore, an adjusting of the apparatus   to pillars of varying thickness  is made merely by an exchanging of the crushing tools having dimensions of cutting edges which are selected in accordance with the prevailing distances between the reinforcing bars.
