Title: Composition for producing phosphine-containing gas
Inventor: HORN FEJA FRANZISKUS DR
IPC: A23B9/18
Filed: 1996-06-07
Abstract: A metal phosphide composition is disclosed for generating a mixture of phosphine and diluent gas(es), presented ready for use in a hydrolysis process or apparatus in the form of a free-flowing particulate metal phosphide material composed of loose particles of said metal phosphide essentially free of metal phosphide dust, essentially free of hydrolysis retarding agents and essentially free of hydrophobic substances in the form of coatings or hydrophobising additives. In use the hydrolysable metal phosphide, preferably magnesium phosphide, is released directly into liquid water under an atmosphere of gas inert to phosphine. The generated mixture of phosphine and inert carrier gas, e.g. CO2, can be used as such or is diluted into a gas mixing chamber with air to a concentration below the ignitability limit before being used in fumigation. The composition is manufactured by reacting a finely divided metal, selected from the group consisting of aluminium, calcium and magnesium with yellow phosphorus in an inert gas atmosphere and in the presence of a catalyst. Throughout the reaction batch and throughout the process, once reacting has commenced, a temperature is maintained within the range of 350°C to 550°C. The metal phosphide is withdrawn as a particulate free-flowing material and is packaged ready for use in phosphine generation in such free-flowing condition, essentially free of dust, essentially free of hydrolysis retarding agents and essentially free of hyrophobising substance in the form of coating or hydrophobising additives, in a gastight container.

Title: Hydrogenation of unsaturated fats, fatty acids or fatty acid esters
Inventor: TACKE THOMAS DR
IPC: B01J23/42
Filed: 1995-02-09
Abstract: A process is disclosed for continuously hydrogenating unsaturated fats, fatty acids or fatty acid esters on a shaped catalyst in a solid bed.

Patent CA-2183903-A1 (CA)
Inventor: PARSONS DAVID ROY
IPC: B08B15/04
Filed: 1996-08-22
Abstract: The process of grinding, sanding and polishing generates dust which causes health hazards and unclean environments. To control the spreading of dust, manufacturers of grinding, sanding and burnishing equipment have adapted vacuum systems to their products to reduce the spreading of dust. This invention, however, confines the dust emitted by the process to the immediate area surrounding the dust generating tool and traps the dust in a filter. The apparatus easily attaches to the dust generating tool through a fastener strip (VELCRO or button snaps) and is flexible enough to adapt to the contour of the tool but rigid enough to house and support the filter. The apparatus can be easily removed from the tool for cleaning of the filter.

Title: Method and apparatus for load balancing among multiple compressors
Inventor: STAROSELSKY SERGE
IPC: F04D15/00
Filed: 1996-08-26
Abstract: Balancing the load between series compressors is not trivial. An approach os disclosed to balance loads for compression systems which have the characteristicthat the surge parameters, S, change in the same direction with rotational speedduring the balancing process. Load balancing control involves equalizing the pressure ratio, rotational speed, or power (or functions of these) when the compressors are operating far from surge. Then, as surge is approached, all compressors are controlled, such that they arrive at their surge control lines simultaneously.

Abstract: The cup-holder is provided with a number of cells for receipt of a cup. Each cell has a side limit which diverges upwardly and is defined by inter-connected alternatively inwardly and outwardly curved walls. The inwardly curved wall is formed of flexible material which deforms resiliently outwardly as the cup is inserted into the cell to frictionally secure the cup therein. Each inwardly curved wall has a continuous inner surface free of any openings therein save and except for a slit formed adjacent to its intersection with the lower wall and, optionally, a vertically-extending line of weakness. The line of weakness is formed by a cut into but not through the latter said wall. The slit and line of weakness are provided to facilitate deformation of the curved wall.

Title: Method of selection of a population or subpopulation of a sample
Inventor: COULTER WALLACE H
IPC: G01N33/543
Filed: 1995-04-11
Abstract: A separation procedure for separating a selected desired or undesired population from a biological sample utilizing relatively heavy, dense particles and gravity sedimentation. The particles have one or more reactants bound thereto which are specific to and will bind with the selected population. The particles preferably are mixed with the sample by repeatedly causing the particles to settle through a substantial portion of the sample to bind to the selected population. The particles with the bound selected population then are allowed to preferentially settle in the sample and the supernatant including the non-selected population is separated from the particles with the selected population bound thereto. The particles can be heated for sterilization and endotoxin removal.

Abstract: La présente invention concerne des virus d'insectes capables de tuer au moins un insecte nuisible cible plus rapidement que les virus précédemment connus. L'invention concerne également la séquence ADN responsable de ce phénotype d'accélération létale. On obtient une meilleure vitesse létale lorsque le virus de la présente invention contient également un gène <u>egt</u> non fonctionnel permettant de réduire le phénomène d'alimentation de la larve infectée, de bloquer sa croissance et de faciliter l'accélération létale de l'insecte infecté. Un virus d'insecte à accélération létale choisi comme exemple spécifique est le brin V-8 du AcMNPV. Le phénotype d'accélération est situé sur un fragment <u>Mlu</u>I à <u>Esp</u>I des unités 1.93 à 3.27 de la carte du génome du AcMNPV, et sa séquence est fournie ici avec le SEQ ID NO:.... V8vEGTDEL est le dérivé inactivé par <u>egt</u> du V8 du AcMNPV; la combinaison de l'accroissement de la virulence du génotype du V-8, par exemple, avec l'inactivation du gène codant l'ecdystéroïde glycosyle transférase procure d'autres améliorations (telles qu'une meilleure diminution du délai létal après infection). En outre, un tel baculovirus à déficience Egt peut encore être modifié pour exprimer une protéine affectant l'ecdysis. L'invention concerne également des procédés de production de virus d'infection à accélération létale, des compositions insecticides améliorées et des procédés améliorés de lutte contre les insectes.

Title: Contrast enhancement by spatial histogram analysis
Inventor: SCHULTZ JOHN C
IPC: G06T5/00
Filed: 1995-09-18
Abstract: A method for automatic analysis and enhancement of digitized images to identify the area of interest (AOI) from background areas divides a digitized image into a number of regions, and calculates histograms of gray scale or density for each region. An image of the regions in histogram space is created according to a selected sequence of the regions, chosen to preserve spatial proximity. This image is then processed by peak detection to identify features grouped spatially and by similarity of histograms. From this the AOI is identified, and the contrast enhancement is applied to the original image, according to the characteristics of the output device. The method is particularly adapted for enhancing medical X-ray images, for output to viewing devices.

Title: Refrigerator mullion
Inventor: BANICEVIC NEDO
IPC: F25D23/08
Filed: 1997-05-29
Abstract: A refrigerator cabinet has an outer metallic shell into which is inserted a one-piece plastic interior liner having a fresh food compartment separated by a mullion wall from the freezer compartment. The mullion wall is part of the interior liner. A metallic reinforcing mullion strap extends between side walls of the exterior cabinet shell to reinforce the side walls and prevent buckling. The mullion strap extends through an open space between the fresh food compartment and freezer compartment on the interior liner. The mullion strap does not touch the interior liner and is surrounded by thermally insulating foam whereby heat loss through the mullion strap from the refrigerator compartment is reduced. Further, the mullion wall of the interior liner is covered by a plastic mullion cap which protects the mullion wall of theinterior liner from stresses associated with door closure and includes a decorative mullion cover in which a heater is provided to compensate for sweating associate with heat loss through the mullion cap to ambient. By using a plastic mullion cap, heat loss is significantly less than using a metal mullion bar directly exposed to ambient.
