Abstract: ABSTRACT OF THE DISCLOSURE         The invention provides a new high temperature isotopic exchange fuel processing loop for tritium recovery in which tritium is exchanged out of impurities such as tritiated ammonia, methane and water by swamping with Ha and isotopically equilibrating the mixture in a high temperature reactor.  Downstream of the reactor is a Pd/Ag permeator for separation of the hydrogen from the impurities, the separated hydrogen being sent to an isotope separation system for tritium recovery and the residual impurities being recycled.  The process eliminates the need for impurity oxidation and electrolysis of DTO and does not rely on complicated catalytic decomposition reactions.

IPC: G06F3/14
Filed: 1991-09-23
Abstract: Edge  enhancement method and apparatus  for dot matrix devices wherein a group of gradient mask matrices are applied to a "current matrix", wherein a TBAP (To Be Adjusted Pixel) is surrounded by neighboring pixels, to determine if the TBAP is at a location where a change of brightness occurs.  From this matrix operation, a conclusion is derived as to the existence or non-existence of an edge and the direction of the brightness change.   The current matrix and a predetermined number of previously evaluated and yet to be evaluated pixels are then compared to a set of  reference bit patterns which depict possible segment changes  to be corrected.   If the result indicates that the TBAP is on an edge of a changing edge segment, a corresponding code will be generated to modify the TBAP to enhance the smoothness of a segment transition.  In the case of an electrophotographic printing machine, the specific code will change either the location or the size of the TBAP; whereas in the case of a monochrome screen display, the specific code will change the intensity of the TBAP.

Title: Chymosin recovery and purification
Inventor: HEINSOHN HENRY G
IPC: C12N9/00
Filed: 1990-06-13
Abstract: 2058453 9015865 PCTABS00003 This invention provides a method of recovering and purifying chymosin from fermentation used for microbial production of chymosin.  The fermentation mixture is filtered to provide a filtrate containing the chymosin. The filtrate is first prepared by either adjusting it to a low pH, such as about 2 and/or adjusting the salt concentration of the filtrate to at least about 2M. The aqueous filtrate mixture is contacted with a phenyl-sepharose resin, which selectively binds the chymosin from the filtrate. The filtrate remaining after the contact with the phenyl-sepharose resin is discarded, and the phenyl-sepharose resin column is eluted with water or dilute salt solution to obtain substantially pure chymosin in a single elution step.

Filed: 1990-07-18
Abstract: The invention comprises diamines having a 5-t-butyl-1,3-benzene dicarboxylic moiety linked on both sides to phenylene diamine by an amide bond (tBuIPA-diamines). By reacting these diamines with aromatic difunctional acid derivatives amorphous polymers having high glass transition temperatures (Tg) can be prepared. If aliphatic diacid derivatives are used, the resulting polymers have a lower Tg, but have the advantage of melt-processability. The t-BuIPA diamines can also be used in the preparation of polyimides, being reacted with tri- or tetra-carboxylic anhydrides or with imide group-containing acid derivatives.
Patent CA-2060810-A1 (CA)
IPC: F41J1/01
Filed: 1992-02-07
Abstract: The system is for use on outdoor firing ranges. Target cards bearing the printed targets are secured to a 4ft square panel made of Coroplast (trademark), which is extruded twin-walled polypropylene sheet. The sheet is formed with built-in curvature, which is sufficient to render the target panel rigid, even though the material is thin enough that bullets can pass through without punching-out. Because of the curvature, no frame is required to keep the panel rigid. Scoring rings are printed on the face of the panel, together with markings that allow an attendant to align fresh target cards with the scoring rings. Two, or three, plies of Coroplast may be welded/glued face to face, for larger targets.

Abstract: ABSTRACT OF THE DISCLOSURE        A structure and a method for sensing oxides of nitrogen in a gas, for example, the exhaust gas of an internal combustion engine.  The measurement gas along with oxygen provided by a solid state electrochemical oxygen pumping cell is passed through an oxidation catalyst to oxidize and remove any reducing species in the gas, e.g., carbon monoxide, hydrocarbons, and hydrogen.  The oxides of nitrogen are then sensed by a gas sensor which otherwise would respond to both oxides of nitrogen and reducing species in the gas.
