Title: Satellite television broadcasting receiver
Inventor: KAWAKAMI SHIGERU
IPC: H04N5/60
Filed: 1992-06-15
Granted: 1999-07-27
Abstract: The present invention relates to a satellite television broadcasting station which receives waves from a satellite, selects a broadcasting station and obtains an FM demodulated video signal by passing a selected signal through the band-pass filter. In this satellite television broadcasting receiver, the video signal superposed with a large energy dispersion signal is inputted to the first clamping circuit at a, low level, to eliminate the energy dispersion signal. Thus, a room is provided in the dynamic range of the amplifier at the later stage and the DG and DP of the amplifier at the later stage are maintained at a satisfactory level by the second clamping circuit. As a result, even in the case of a satellite television broadcasting in which the level of the energy dispersion signal superposed on the video signal is large, distortion which occurs due to the nonlinearity of the amplifier can be reduced substantially so that the image can be reproduced on the screen in a satisfactory condition without an interference of flickering.

Title: Microwave heated digesting system for digesting materials to be analyzed
Inventor: HASWELL STEPHEN J
IPC: G01N35/08
Filed: 1992-07-06
Granted: 2004-03-16
Abstract: A continuous flow microwave heated digesting system includes a source of microwave radiation into a chamber, thin walled chemical resistant and microwave transmissive tubing with-in such chamber onto which the microwave radiation impinges to heat contents thereof, and means for passing through such thin walled tubing material to be digested in a digesting medium therefor, so that the material is digested. It has been found that for quick and effective digestions the tubing will often be of an internal diameter in the range of 0.5 to 1 mm. and will be heated for a length in the range of 5 to 50 meters, so the heating time of a sample to be digested will be at least five seconds and normally gill be less than 3 minutes, during which time such digestion will be essentially completed. Means are provided for inserting into a stream of carrier liquid, such as water, a slug, such as a 1 ml. slug, of sample in digesting liquid (acid), which is passed through the tubing (which is coiled inside a microwave chamber), and after completion of digestion is cooled and is passed directly to an atomic absorption spectrometer, where its spectrum is recorded and the analysis of the sample is reported.      The slug of sample in acid.may be added to the system via an injection valve and loop by means of syringe injection or other suitable charging means. Backpressure will be maintained on the system and filtration of any undigested solids will very prefer-ably be effected to prevent any possible blockages of the system.

Title: Hemicellulase supplement to improve the energy efficiency of hemicellulose-containing food and animal feed
Inventor: FODGE DOUGLAS WALTER
IPC: A23L11/00
Filed: 1991-05-29
Granted: 2004-09-28
Abstract: Soil microorganisms are obtained that produce a hemicellulase which is particularly useful in increasing the available energy content of hemicellulosic foodstuffs.      These microorganisms can be cultured per se or can be used as sources of genetic information with which to engineer other microorganisms to produce the enzyme. Thus, commercially useful quantities of native or recombinant hemicellulase can be produced with cultures consisting essentially of microorganisms that produce the enzyme. The hemicellulase, a culture consisting essentially of a microorganism that produces such a hemicellulase, or a fermentation broth comprised of such a culture and hemicellulase can then be employed in a consumable composition containing complex carbohydrates which the enzyme degrades, enhancing the nutritional value of the composition.

Granted: 1997-10-07
Abstract: In a structure for cooling an integrated circuit (IC), a hollow cylindrical member is mounted on a cold plate and receives a heat conductor therein.  The heat conductor is a cylindrical member which is closed by a flat plate at one end thereof.  Silicone gel fills a gap between the hollow cylindrical member and the heat conductor and allows the heat conductor to move due to the elasticity thereof.          When the cold plate is fixed in place on the IC which is mounted on a printed circuit board, the heat conductor moves in matching relation to the height and inclination of the IC.  As a result, the heat conductor and IC are brought into close contact with each other.  A compound intervenes between the heat conductor and the IC to enhance the close contact of the heat conductor and IC.

Title: Valve cage for a rod drawn positive displacement pump
Inventor: IVEY RAY KENNETH
IPC: F04B47/12
Filed: 1994-05-02
Granted: 1997-05-13
Abstract: A valve cage whose tubular side wall has a progressively diminishing thickness between the seat and the stop means, whereby the bore is tapered and upwardly enlarging in that interval. Therefore the flow area between the ball provided in the bore and the side wall increases as the ball ascends. The side wall has ball guide ribs which project inwardly and increase in height at the same rate as the wall thickness diminishes, so that the ribs form a race of constant diameter, for guiding the ball as it moves vertically and preventing it from moving laterally. The ball stop is positioned at the top of the cage and the external thread for connection with the pump barrel is positioned intermediate the ends of the cage. This arrangement enables the seats of the travelling and standing valves to come close together at the bottom of the down stroke of the plunger. At their upper ends, the ball guide ribs join to form a ball stop that has a hemispherical configuration, to better distribute contact between the valve ball and the stop.

Inventor: SURGUY PAUL WILLIAM HERBERT
IPC: G02F1/133
Filed: 1993-10-04
Granted: 2003-05-20
Abstract: A liquid crystal cell comprising a matrix of pixels defined by areas of overlap between members of first and second sets of orthogonal electrodes has its pixels selec-tively set to first and second states by addressing the pix-els in rows. The pixels of a given row are first set to a first state by applying an erase signal (12) to the corresponding row conductor simultaneously with applying bipolar data signals (8, 9) to all the column conductors. Selected pixels of the row are subsequently set to a second state by apply-ing a strobe signal (10) to the row conductor simultane-ously with applying a bipolar data signal (9) to the rele-vant column conductors, another bipolar data signal (8) being applied to the column conductors corresponding to non-selected pixels. The start of the strobe signal coin-cides with the start of the active central portion of the data signals but the strobe signal continues beyond the end of this portion, enabling the addressing rate to be increased.
