Title: Fatty-acid-based plastics
Inventor: FRISCHE RAINER
IPC: C08G18/30
Filed: 1990-06-26
Abstract: The present invention relates to plastics that can be obtained by reacting unsaturated and/or hydroxyl-group-containing fatty acids or their esters or mixtures of various such fatty acids and esters with bifunctional ester- and/or amide-forming compounds and, if necessary, subsequently converting any possibly existing ethylenic double bonds, to give difatty acid diamides, difatty acid diesters, difatty acid amide esters, monofatty acid amide amines or monofatty acid amide alcohols as monomer components which contain at least two functional groups suited for linkage to give polymers, in particular ethylenic double bonds, hydroxyl groups, epoxy groups or amino groups, and by linking the said compounds in the known way via a second group of bifunctional compounds that are capable of reacting with these free functional groups to give the desired plastics.

Title: In vitro method and probe for detecting the presence of the ring shaped particle and malignancy in humans and animals
Inventor: GUERRERO ROBERT R
IPC: C12Q1/68
Filed: 1990-08-09
Abstract: Abstract of the Disclosure An in vitro method and probe for determining the presence of the ring shaped particle (RSP) tumor marker and for detecting the presence of malignancy in humans and animals comprises capturing the marker out of a biological fluid containing cancerous cells onto a substrate and detecting the presence of the RSP tumor marker on the substrate as an indicator of the presence of the malignancy. One preferred method involves using an anti-RSP antibody (rspAb) selected from one or more of  the monoclonal,  polyclonal  and affinity purified antibodies to capture the tumor marker from a sample of a biological fluid such as blood serum, sputum, urine, irrigation fluids, etc.. The tumor marker is captured onto a substrate with an rspAb and its presence on the substrate is detected using common detection systems, such as color development techniques.  In one preferred form, the tumor marker is detected on the substrate by reaction with a tRNA-photobiotin-streptavidin-alkaline phosphatase probe.  Another preferred method involves using a transfer ribonucleic acid (tRNA) probe which is specific to the aminoacyl transfer RNA synthetase reactive site on the marker and detecting the presence of the RSP by color development techniques using a tRNA-photobiotin-streptavidin-alkaline  phosphatase probe.

Title: Smoke stack exhaust system
Inventor: HOUSTON CLARENCE H
IPC: B01D47/06
Filed: 1990-10-03
Abstract: ABSTRACT OF THE DISCLOSURE     A water-spray gas-scrubbing device of water-cooled metallic construction for use with a processing facility producing gases containing extractable particulate waste and having a conduit, and a gas-scrubbing chamber in which the combustion gases are washed with water sprays to remove particulate material. The washed gases are vented to the atmosphere and the scrubbing water passes downwardly through a series of metallic mesh filter trays in a filter tower to remove particulate material from that water which is then re-circulated to the scrubbing chamber. The conduit and the combustion chamber are formed as hollow metallic wall structures with inner and outer metallic walls, and cooling water flows continuously through those hollow wall structures to reduce thermal damage thereto.

IPC: B65D83/00
Filed: 1990-10-16
Abstract: A pump is mounted in one end of a cylindrical con-tainer for storing a liquid, for drawing the liquid stored in the cylindrical container and discharging the drawn liq-uid out of the cylindrical container.  A gasket is slidably disposed in the opposite end of the container in keeping the liquid sealed in the cylindrical container.  The gasket is movable toward the pump as the amount of the liquid stored in the cylindrical container is reduced when the liquid is discharged from the cylindrical container by the pump.  The gasket has a slanted surface facing the pump for contact with the liquid stored in the cylindrical container, the slanted surface being inclined progressively toward the sec-ond axial end.  The gasket also has a cylindrical surface defining a communication hole defined axially therethrough and having an inner end opening at the slanted surface.  The communication hole provides communication between the inte-rior and the exterior of the cylindrical container.  A cap comprises a cap body inserted in the communication hole and a flange closing an outer end of the communication hole.  At least either one of the cap body and the cylindrical surface has at least one axial groove.  Air bubbles which may have been trapped in the container when the liquid is charged into the container move along slanted surface into the com-munication hole and then is escaped from the container through the groove.

Title: Ni-cad battery charge rate controller
Inventor: FAULK RICHARD A
IPC: G06F1/26
Filed: 1991-09-27
Abstract: NI-CAD BATTERY CHARGE RATE CONTROLLER              ABSTRACT  OF THE DISCLOSURE     A current limiter placed in the charge path of a battery limits the charge rate that a battery charger can provide to the battery.  The battery temperature, voltage, and current are monitored to determine whether the battery can handle a faster rate of charge than the current limiter allows.  If the battery can handle a higher rate of charge, a transistor configured in parallel with the current limiter is enabled which by-passes the current limiter and allows the battery charger to charge the battery at a higher rate.

Abstract: Abstract of the Disclosure A method and apparatus for determining the position of a ball on a playing field during a game, for example a football in the game of American rules football, is disclosed.  The apparatus includes a guide ramp having a length corresponding to the first down distance, having sighting lasers at each end and a spotting laser that moves along the guide ramp.  At the beginning of a first down series, the guide ramp is moved to and anchored at a position at which one of the sighting lasers projects a mark corresponding to the position of the ball.  If a play then occurs in which the ball is advanced to a location within the first down distance, the spotting laser is moved along the guide ramp until its projected mark corresponds to the position of the ball; if a loss-of-yardage play occurs in which the ball is located outside of the first down distance, the initial sighting laser can be removed from the guide ramp and moved to the ball location, connected to the guide ramp by way of a chain.  A meter may be connected to the spotting laser to measure and display the distance from either or both ends of the guide ramp  (yards advanced, yards to go).
