Abstract: An open bowl for a vertical turbine pump, includes a bowl body having an inner wall and an outer wall, both walls being of substantially constant optimum thickness, surrounding a vertical axis and connected by diffuser vanes which define hydraulically optimized diffuser passages through the bowl body extending from a bottom end to a top end, the diffuser vanes being radially hollow and providing open paths through the inner and outer walls to a cavity surrounded by the inner wall; a flange at the top end of the outer wall for attachment of a discharge conduit for the pumped fluid; provision on the bottom end of the outer wall for attaching to a flange of a suction bell; further provision on an inner surface at the top of the inner wall for providing sealing engagement with an upper end of a separable substantially cylindrical bearing housing; and provision at the bottom end of the inner wall for attaching to a flange of the bearing housing. The open bowl concept provides a light weight pump which provides better metal flow, solidification control, and cooling during casting by elimination of drastic section thickness variations in the bowl body.

Abstract: An apparatus and a method for pasting of plastic film onto workpieces provides for the workpieces to be carried in sequence over a table and between a roller pair; precut sections of the plastic film being delivered by a conveyor cylinder in synchronized sequence to correspond with the workpieces, and a broad-slit nozzle directs a supply of heated air into the roller gap to effect pasting of each film section to a preselected region of the corresponding workpiece. A temperature sensor above the path of the workpieces after leaving the roller gap and a subsequent table temperature sensor provide signals to a control means, whereby a temperature directly after pasting of a pasted region of the workpiece at which a good pasting is performed is determined as a nominal value, and the supply of heated air to the broad-slit nozzle is regulated in response to the signals.

Title: Process for preparing conjugate vaccines including free protein and the conjugate vaccines, immunogens, and immunogenic reagents produced by this procedure
Inventor: LEES ANDREW
IPC: A61K38/00
Filed: 1998-01-07
Granted: 2012-04-24
Abstract: A process for preparing a protein-polysaccharide conjugate includes racting a protein with a polysaccharide to produce a mixture including a protein-polysaccharide conjugate and free protein. At least one unreacted reagent or low molecular weight component is removed from this mixture, without removing all of the free protein, to provide a purified mixture that contains the protein-polysaccharide conjugate and free protein. This purified mixture can be used as a conjugate vaccine, immunogen, or immunological reagent. Keeping the free protein in the purified mixture with the conjugate saves time and money in the conjugate production process. In another aspect of the invention, the purified mixture of the protein-polysaccharide conjugate and free protein is reacted with a hapten to produce a conjugate mixture including a hapten-protein conjugate and a hapten-protein-polysaccharide conjugate. Alternatively, the hapten-protein conjugate can be prepared first, this conjugate then reacting with a polysaccharide reagent to produce the conjugate mixture. This conjugate mixture can be treated further to remove the free hapten. The conjugate mixture, including the hapten-protein-polysaccharide conjugate and the hapten-protein conjugate, also can be used as a conjugate vaccine, immunogen, or immunological reagent.

Title: Safety limiter for powered vehicles
Inventor: SILVERNAGLE DARIN
IPC: B60K26/02
Filed: 2000-01-24
Granted: 2008-04-01
Abstract: A vehicle control unit is disclosed which can be coupled between a tachometer sensor and an electronic ignition system on a vehicle. The unit is also coupled to a speedometer sensor to measure the vehicle's speed. The vehicle control unit limits the vehicle speed by modifying the tachometer signal from the tachometer sensor and providing the modified tachometer signal to the ignition system. The tachometer signal is a pulse train which is used by the electronic ignition system to determine ignition timing. The vehicle control unit limits both ground speed and engine speed by suppressing pulses from the original tachometer signal to prevent the combustion of fuel and thereby reduce engine power when the ground or engine speeds exceed predetermined limits. The vehicle control unit is microcontroller-based and preferably includes a logging function and an acceleration sensor. The microcontroller is coupled to the acceleration sensor to detect the peak accelerations experienced by the vehicle. The microcontroller stores peak accelerations above a predetermined limit, along with excessive ground and engine speeds, as part of a fault record a nonvolatile memory. The records can be examined by management personnel to identify reckless vehicle operators. Corrective action can then be taken to protect personnel and equipment. A handheld programming unit is also disclosed herein for programming the predetermined limits and for retrieving fault records. The programming unit can display and summarize fault records, and can be used to transport the fault information to a central computer system for archiving and more extensive analysis.

Granted: 2005-05-17
Abstract: Dans certaines maladies auto-immunes et malignes, on a observé une augmentation de l'expression des protéines de fixation du facteur FGF (FGF-BP) sécrétées. On a notamment découvert que les sécrétions de protéines de fixation du FGF par les tumeurs entraînent la mobilisation et l'activation de FGF (facteurs de croissance des fibroblastes) stockés localement, qui peuvent servir comme molécule de transition angiogénique. On a découvert en outre que, chez un modèle animal souffrant de sclérose en plaques, l'exacerbation de la maladie s'accompagne d'une augmentation de la protéine FGF-BP. A l'aide de ribozymes, on peut produire le clivage de l'ARNm de la protéine FGF-BP. Par conséquent, l'administration de ribozymes entraînant le clivage de l'ARNm de FGF-BP en quantités suffisantes pour inhiber le processus morbide déclenché par la protéine FGF-BP, est appropriée.

Abstract: An improved route is provided for producing seeds capable of forming a Brassica napus F1 hybrid via plant breeding wherein the vegetable oil of the seeds exhibits a highly elevated oleic acid (C18:1) content of at least 80 percent by weight (e.g. 80 to 86 percent by weight) and a reduced linolenic acid (C18:3) content of no more than 3 percent by weight (e.g. 1 to 3 percent by weight) based upon the total fatty acid content. The female parent plant (i.e., the seed parent) possesses a homozygous modified FAD-2 gene pair for elevated oleic acid production solely in either the A-genome or the C-genome, and the male parent (i.e., the pollen parent) possesses a homozygous modified FAD-2 gene pair for highly elevated oleic acid production in both the A-genome and the C-genome. Both parent plants also include at least one homozygous modified FAD-3 gene pair for reduced linolenic acid production. An endogenously formed Brassica napus oil is provided that is particularly well suited for use in frying application. Such oil exhibits further stability in view of the low concentration of linolenic acid that concomitantly is produced within the seeds.

Abstract: On décrit un système qui permet à un système de gestion des connaissances actives accessible sur Internet de créer un coordinateur d'agent intelligent. L'architecture permet de fournir des informations n'importe quand et n'importe où à un usager qui nécessite ces informations, dans un format approprié en fonction des caractéristiques de l'usager à ce même instant. La personnalisation des informations est également rendue possible du fait qu'on prend en considération l'historique des interactions de l'usager avec diverses applications et des situations du moment en temps réel telles que  'qui est l'usager en ce moment même, où se trouve l'usager en ce moment même, à quel moment l'usager est en session sur le système''. Un sous-système rapide et à échelle variable de priorisation des informations est également utilisé pour incorporer l'opinion du coordinateur d'agent intelligent, les préférences de l'usager, et l'historique des interactions de l'usager. Ce traitement décharge l'agent d'une grande partie du traitement normal ce qui permet aux agents d'être plus sophistiqués et précis sans compromettre la caractéristique de changement d'échelle du système. En outre, la reconnaissance de la parole et la synthèse de la parole combinées à une représentation animée de l'agent intelligent et à des entrées tactiles assurent une interaction efficace, intuitive et émotionnelle avec le système.
