Patent CA-2277192-C (CA)
Title: Nuclear transfer with differentiated fetal and adult donor cells
Inventor: STICE STEVEN L
IPC: A61K35/12
Filed: 1998-01-05
Granted: 2011-03-15
Abstract: An improved method of nuclear transfer involving the transplantation of donor differentiated cell nuclei into enucleated oocytes of the same species as the donor cell is provided. The resultant nuclear transfer units are useful for multiplication of genotypes and transgenic genotypes by the production of fetuses and offspring, and for production of isogenic CICM cells, including human isogenic embryonic or stem cells. Production of genetically engineered or transgenic mammalian embryos, fetuses and offspring is facilitated by the present method since the differentiated cell source of the donor nuclei can be genetically modified and clonally propagated.

Abstract: A snow shoveling machine comprising an engine and an auger housing accommodating therein an auger paddle. The engine is actuated to thereby rotate the auger paddle. The auger housing includes an upper half and a lower half. The upper half is made from resin. The lower half is formed of a sheet of steel. The upper and lower halves are connected to each other through a connecting member. The connecting member serves a function of reinforcing the auger housing. As snow collected by the auger paddle is thrown upwardly into a snow throwing aperture formed in the upper half, some snow fails to enter the aperture. The connecting member serves to allow such snow to fall to the auger paddle.

Abstract: A heat-shrinkable multilayer film comprises (A) a first layer, which is an outer layer, and which comprises polyolefin; (B) a second layer comprising at least one member selected from the group consisting of polyolefin, polystyrene, and polyurethane, wherein the second layer has a thickness of from about 10 to 50 percent, based on a total film thickness; (C) a third layer comprising a polyamide having a melting point of 160 .degree.C and below; and (D) a fourth layer, which is a n outer layer, the fourth layer comprising polyester. The first layer preferably serves as a seal layer in a heat-shrinkable bag. The third layer provides enhanced orientability of the tape from which the film is formed, thereby providing improved total free shrink and lower shrink temperature. The third layer also provides greater optical clarity and permits the presence of a thicker polyamide layer, thereby increasing impact strength and improving the O2-barrier of the film. The high melting polyester of the fourth layer permits at least two bags, having product therein, to be stacked on top of one another and sealed simultaneously, without sticking to one another, thereby doubling the output of a vacuum chamber machine. A bag and a process of making a packaged product are also disclosed.

IPC: B05C3/12
Filed: 1999-05-18
Granted: 2007-07-17
Abstract: The present invention is a device and a method of applying a coating to a we b. The device comprises a feed nozzle (2) coupled to stiffener (11) coupled to a spring (30) coupled to a feed nozzle slide position/force adjuster (17). The feed nozzle (2) comprises a fluid reservoir (12), a feed pipe (6), a metering surface (4), end seals (27) and a back seal (3). The stiffener spring, as the frame deflects and polymer covered rolls deform, permits the rotation of the feed nozzle (2) so a proper geometry is maintained, permitting increased control and a wider film thickness control range for a specific nozzle shape. This device permits greater film thickness control, ability to process at much higher speeds than currently achievable, and a wider range of film thickness. This device permits coatings to be applied at much wider ranges of rheological characteristics. Coatings can be applied at high er percent solids with improved characteristics.

Granted: 2009-02-10
Abstract: A process of fabricating a composite vessel includes the steps of: A) fabricating a thermoplastic liner for the vessel; B) overlaying a layer comprising fiber and a thermoplastic material (preferably by winding commingled filaments, rovings or yarns) onto the thermoplastic liner to obtain a composite intermediate structure (the fiber and thermoplastic material can be heated if desired during the overlaying, e.g. winding, step); C) heating the composite intermediate structure in a mold while applying at least one force thereto tending to urge the composite intermediate structure against and into shape of the interior walls of the mold; D) continuing step C) until the thermoplastic liner and the overlaid layer consolidate to form a composite vessel; E) cooling the mold and composite vessel until the composite vessel is solidified; and F) removing the formed composite vessel from the mold. The at least one force applied during step C) may be obtained by introducing gas pressure into the interior of the composite intermediate structure. Suitable materials for the thermoplastic material include: polyethylene, polypropylene, polybutylene terephthalate and polyethylene terephthalate. The resulting composite vessel exhibits superior mechanical and aesthetic properties.

IPC: A01M1/20
Filed: 1999-11-15
Granted: 2009-09-15
Abstract: Compositions and methods for controlling the population of insects are disclosed. The compositions include a feeding stimulant for a particular insect, an effective amount of a 1-arylpyrazole or nicotinyl insecticide to kill a desired insect, at a concentration which is not typically toxic when applied to a plant in the absence of a feeding stimulant and the insect consumes an ordinary amount of toxin during the course of normal feeding, but is toxic when applied in conjunction with a feeding stimulant which causes the insect to consume more of the toxin than would normally be consumed during normal feeding. The use of normally non-toxic amounts of insecticides allows one to minimize the residual insecticide present on the crops. Also, by using a selective feeding stimulant along with a normally non-lethal concentration of insecticide, beneficial insects which are not attracted to the feeding stimulant are not effectively killed off, and detrimental insects which are attracted to the feeding stimulant are effectively killed off.

Abstract: The invention relates to conductive heaters, and has its objective to provide a material that exhibits a uniform heating effect over the full area of the heater, relatively free from hot and cold spots, a further objective being to maintain the heater pliable. These objectives are met by a conductive material comprising finely divided carbon particles uniformly dispersed in an elastomeric carrier there being carbon particle levels of 20% to 75% by dry weight to carrier levels. Preferably, the carrier is an elastomeric polymer. A further aspect of the invention is a method of forming a compound for an electrically conductive heater comprising stirring fine carbon particles into a polymer base containing an anti-adsorption compound, to achieve carbon particles to polymer levels of 20% by dry weight to 75% by dry weight, and subjecting mixture to high speed stirring for a pre-determined period of time, with the maintenance of the mixture below a predetermined level, to grind the carbon particles to a predetermined final fineness.

Abstract: Cette invention se rapporte à un dispositif de finition utilisé pour former un coin entre deux panneaux de placoplâtre et comportant à cet effet une jointure souple (100) le long d'un axe prédéterminé. Deux ailes (102, 104) sont reliées à cette jointure souple (100) et s'étendent vers l'extérieur dans un sens divergent par rapport à cette jointure souple, afin de former un coin ayant un angle réglable. Chaque aile (102, 104) possède une surface frontale (106), une surface arrière (108) et un bord (204) en position distale par rapport à la jointure souple (100). Ce bord (204) vient en about contre l'un des panneaux de placoplâtre et possède une épaisseur égale à celle du panneau de placoplâtre. Dans une variante, ce bord (204) possède une épaisseur réglable lui permettant de s'adapter aux diverses épaisseurs du panneau de placoplâtre. Une couche d'amorce ou de stratifié adhésif est appliquée sur la surface frontale des ailes, pour que de la peinture puisse adhérer à ladite surface frontale. Ce dispositif de finition est capable de former à la fois des coins intérieurs et des coins extérieurs. Pour former des coins intérieurs, le dispositif de finition se plie le long de la jointure souple (100). Pour former des coins extérieurs, des bandes parallèles à la jointure souple (100) sont retirées de la surface arrière des ailes (102, 104) et le dispositif de finition est plié le long des ouvertures ainsi créées.
