Patent CA-2265726-A1 (CA)
Inventor: DONER JOHN R
IPC: H04W16/12
Filed: 1997-09-12
Abstract: L'invention concerne un plan d'affectation de fréquences pour un système de communication sans fil. Ce plan permet de s'adapter pour répondre à la demande croissante et peut ainsi passer d'un plan de réutilisation de faible densité à douze cellules à un plan de réutilisation de grande efficacité à trois cellules. Le spectre radio disponible est d'abord divisé en trois plages et chaque plage est ensuite divisée en quatre groupes. Les fréquences de chaque plage sont affectées de manière séquentielle aux quatre groupes. Ces groupes sont ensuite identifiés comme groupes pairs et groupes impairs. Les groupes à douze cellules sont disposés en formes rectangulaires avec une largeur de quatre cellules par une hauteur de trois cellules. Un premier ensemble de trois cellules dans la partie supérieure gauche est affecté à l'utilisation d'un premier groupe de fréquence à indice pair. Un deuxième groupe de trois cellules situé ans la partie gauche inférieure est affecté à l'utilisation d'un deuxième groupe de fréquence à indice pair. Un troisième et un quatrième groupe de cellules associés aux positions supérieure droite et inférieure droite sont affectés aux premier et deuxième groupes de fréquences à indice impair. Lorsque la densité du trafic augmente, les cellules sont divisées en six secteurs, chaque secteur étant affecté au groupe de fréquences pair ou impair pour atteindre un facteur de réutilisation de six. La sectorisation d'un schéma de réutilisation de fréquences toutes les trois cellules est ensuite mise en oeuvre en remplaçant les affectations de fréquences obtenues dans la colonne de trois cellules située le plus à gauche par une colonne centrale non adjacente d'un groupe de cellules situé le plus à gauche. Afin de mettre en oeuvre ce programme de réutilisation de fréquences toutes les trois cellules, dans la colonne de cellules située le plus à droite, des affectations de fréquences paire et impaires sont remplacées de la même manière entre la colonne située le plus à gauche et la colonne centrale non adjacente du groupe de cellules vers la droite.

Title: Method and apparatus for the manufacturing of paint rollers
Inventor: HANSEN GOERAN
IPC: B05C17/02
Filed: 1997-10-15
Abstract: The invention relates to a method and a device for the manufacture of paint rollers by winding a textile fabric (3) onto a plastic tube (2) along a spiral-shaped line. According to the invention, a number of tube elements (6), having a length suitable for a paint roller, are slipped onto a revolving mandrel (1). The tube elements are clamped together so as to engage one another and so as to allow them to be rotated together with the mandrel (1). The mandrel is rotated at the same time as the fabric is wound on and attached to the tube elements, after which the fabric is cut at the joints (8) between the tube elements. Due to the invention, the cutting can be performed in the same machine without the risk of damaging the mandrel. As the cutting is made through the fabric only, this entails much less knife wear and is less energy-consuming. Preferably, the tube elements have a toothing at their axial ends for mechanical interconnection at the joints between the tube elements and with the mandrel (1).

IPC: B65B9/20
Filed: 1997-12-11
Abstract: A liquid product carrying plastic film pouch (10) having a straw (12) free-floating in the liquid product (11) is described. The liquid product (11) contained within the inner chamber (13) of the pouch occupies from about 60 % to about 90 % of the volume of the inner chamber (13) of the pouch and a portion of air from the remaining volume is evacuated in sufficient quantity to permit the side walls (14, 15) of the pouch to be collapsed against one another when the pouch is grasped by the hand of a user person. By collapsing the side walls (14, 15) together the straw (12) located within the liquid can be grasped and manipulated to puncture the plastic film pouch (1) to extend a portion (12') of the straw (12) exteriorly of the pouch whereby to extract liquid therefrom. The pouch (10) is made of a multilayer resin film having an inner sealant layer (26) formed of a linear low density ethylene-octene copolymer or very low density ethylene copolymer (octene or other copolymers) such that when the straw punctures the film, the inner sealant layer (26) forms a membrane about the straw which exhibits a self-sealing behavior so as to prevent leakage in the punctured region as liquid is extracted from the pouch (10) through the straw (12). The machine and method of fabrication is also disclosed.

Title: Data processing apparatus and method
Inventor: GARDNER PAUL ANTON RICHARDSON
IPC: G06F9/44
Filed: 1999-06-03
Abstract: A method for evaluating an expression comprises issuing parallel requests to acquire a plurality of operands. If, upon receipt of a first subset of the operands, it is determined that a second subset of the operands is no longer required in respect of a particular time span, the request for the second subset cancelled for that particular time span. If one operand contains an error indication for a particular time span, the method continues with the request for the other operand for that particular time span, and returns an "error" for that particular time span only if the request for the other operand is not cancelled.

Title: Epitopes of the protein pre-m/m of the dengue virus, synthetic peptides
Inventor: REYES ACOSTA OSVALDO
IPC: A61K38/00
Filed: 1998-01-13
Abstract: The present invention relates to five synthetic peptides pertaining to the protein pre-M/M of the dengue-2 virus corresponding to the amino acid sequence 2-31, 45-67, 57-92, 69-93 and 103-124. The immune response to the peptides was evaluated in rats. Recombinant fusion proteins including regions of pre-M/M were constructed. The presence of epitopes for B cells of rats and human beings in the peptides of the protein pre-M/M of the dengue virus was verified. the peptides 3-31 and 103-124 induced neutralizing antibodies against the four serotypes of the dengue virus. The studies of lymphoproliferation with the peptides 57-92 and 3-31 demonstrated crossed recognition of T cells which are peptido-specific to the virus. The rats tested with the dengue-2 virus have demonstrated a protection induced by the peptides 3-31, 57-92 and 69-93. Thus, the presence of sequential epitopes in the protein pre-M/M of the dengue-2 virus and the possible relevance of the same in the immune response against said flavivirus is demonstrated.     The Spanish text is not needed.

Title: Device for carrying out lateral-flow assays involving more than one analyte
Inventor: BROCK DAVID A
IPC: G01N33/543
Filed: 1999-11-22
Abstract: Disclosed is an improvement to a dry assay device for determining the concentration of a first analyte in a sample of body fluid and a second analyte in the same sample of body fluid. The device involves the use of a strip of an absorbent material through which the sample of body fluid flows and wherein the first analyte is determined colorimetrically in a first region of the strip and the second analyte is determined by an immunoassay which takes place in a second region of the strip located downstream from the first region. The improvement involves placing the strip in a hollow casing having a top and a bottom and which is so constructed that when the top and bottom of the casing are mated there is formed a U shaped, body fluid impervious barrier around the first region of the strip to prevent the sample of body fluid from flowing in any direction other than in the direction of the second region of the strip.

Title: Fumonisin detoxification compositions and methods
Inventor: DUVICK JONATHAN
IPC: C12N9/00
Filed: 1998-07-07
Abstract: Methods for identifying organisms capable of degrading fumonisin. Fumonisin can be incorporated into culture medium for selection of organisms resistant to fumonisin and/or capable of growing on fumonisin as a sole carbon source.  Using this method, several organisms have been identified. These organisms can be used to isolate the enzymes and the genes responsible for conferring fumonisin-resistance. The gene can be cloned and inserted into a suitable expression vector so that the protein can be further characterized.  Additionally, the DNA encoding for fumonisin degrading enzymes can be used to transform plant cells normally susceptible to Fusarium or other toxin-producing fungus infections. Plants can be regenerated from the transformed plant cells. In this way, a transgenic plant can be produced with the capability of degrading fumonisin, as well as with the capability of producing the degrading enzymes. Methods for detoxification in grain, grain processing, silage, food crops and in animal feed and rumen microbes are also disclosed.
