Title: Television receiver with auxilliary input connector for video signals of a separated y-c format
Inventor: SENDELWECK GENE KARL
IPC: H04N9/87
Filed: 1990-04-12
Granted: 2000-07-25
Abstract: An auxiliary video input terminal (S-terminal) couples luminance amd chrominance input signals to respective inputs of peaking circuits in the display processor of a receiver.      The chrominance input signal is subjected to pre-distortion (de-peaking) to correct for sideband amplitude distortion in the chrominance peaking filter of the receiver thereby preventing color distortion in displayed images. The luminance signal is subjected to additional peaking at a frequency greater than the characteristic peaking frequency of the luminance peaking filter thereby enhancing the sharpness of wideband luminance input signals displayed by the receiver.

Title: Fire control valve with pivotal latch
Inventor: GRAY CHARLES H JR
IPC: A62C2/04
Filed: 1990-12-31
Granted: 1997-06-03
Abstract: A  valve  installed  in  the  flow  line  of  a flammable or other hazardous flowable material which is normally  open  but  will  be  automatically  closed  to interrupt the flow of flammable or hazardous material to a discharge point in the event of a hazardous condition occurring.  The valve is held in an open position by a fusible link which retains a pivotal latch in engagement with a spring biased valve to retain the valve in open position.

Granted: 2003-08-05
Abstract: An electronic device and method are disclosed for effecting both nerve fiber and body tissue stimulation.      Nerve fiber stimulation is primarily effected by application of pulses, and preferably by application of biphasic pulse pairs the pulses of which are spaced from one another in a pattern such that nerve fiber stimulation applied through plural active electrodes enhances pain suppression. Body tissue treatment is primarily effected by application of a net DC charge, and preferably by application of biphasic pulses that includes a greater number of either negative or positive pulses so that a net DC charge results. The DC charge level is maintained at a substantially constant selected value regardless of pulse variations within established broad limits, and the DC charge level is adjustable between operational modes, as needed.

Title: Dehalogenation of organohalogen-containing compounds
Inventor: HARDMAN DAVID J
IPC: C12P1/00
Filed: 1992-04-16
Granted: 2000-09-19
Abstract: Enzymatic dehalogenation of undesirable nitrogen-free organohalogen compounds is carried out by adding a dehalogenase to an aqueous composition comprising a nitrogen-free organohalogen compound and a nitrogen-containing cationic polymer. The enzymatic dehalogenation of the nitrogen-free organohalogen compound is achieved without any substantial effect upon the nitrogen-free organohalogen compound. The dehalogenation method may be carried out via continuous, batch, or semi-continuous processes.      The composition is especially useful as a paper wet strengthening formulation, and is useful in commercial papermaking processes. The resulting paper product comprises a residue of a microorganism.  Preferably the enzyme is obtained from a biocatalyst, still more preferably from a microorganism. Batch-enrichment of a culture of a dehalogenase-containing microorganism provides a composition capable of substantially eliminating the presence of nitrogen-free organohalogen compounds, which are considered to be pollutants. Cell concentrations of greater than 5 x 10 7 cells/ml are provided.

Abstract: An environmentally controlled toilet designed to neutralize and confine contaminating agents such as bacteria, odors, va pors and other airborne particles inside the bowl by generating and maintaining a cyclone-type air circulation inside the bowl. A bowl (70) with a housing (20), and an air-trapping cavity (76) created inside the bowl (70) by a bowl-skirt (73), confines the con-taminating agents during toilet use and improves the efficiency of the air circulation. Sanitizer and odor conditioner cartridges (31) are employed to neutralize the contaminating agents by releasing sanitizing and odor conditioning agents into the air flow circulated inside the bowl (70). A toilet seat (82) having an ergonomic design has a protective skirt (87) that accommodates a hy-gienic-shield (100). A solution to body heat loss and noise contamination during toilet use is also addressed. The invention is ret-rofitable to existing toilets, and is applicable to portable toilet systems including children's training toilets.

Granted: 1997-10-07
Abstract: A duplicated transmission system in which two optical wavelengths are utilized on each of a pair of optical links with one optical wavelength communicating data and the other optical wavelength communicating a signal designating an active optical link of the pair. Each of the optical links is terminated on a transmit unit and a receive unit. The two transmit units determine which of the optical links is the active optical link, and each of the transmit units then transmits a signal on the second wavelength of the terminated optical link indicating this decision. The second wavelength of the active optical link designates that it isactive, and the second wavelength of the standby optical link designates that it is the standby optical link. Upon reception of the information on the second wavelengths, the receive units both select the active optical link.
