IPC: A61B19/00
Filed: 1997-02-28
Granted: 2002-12-03
Abstract: A hand sanitizing apparatus (10) which uses at least two electrostatic emitters (71-73, 81-83) to dispense germicidal fluid to substantially all the surfaces of a user's hands when both hands are placed in proximity to the electrostatic emitters (71-73, 81-83). The apparatus (10) comprises a frame (11) on which are mounted electrostatic emitters (71-73, 81-83) in preferably two cells (12, 13) which separate spray directed at one hand from spray directed at the other hand, a reservoir (60) of germicidal fluid (50, 51) in fluid communication with the electrostatic emitters (71-73, 81-83), a power source (20) adapted to supply electrostatic energy to the electrostatic emitters (71-73, 81-83), and a dispensing cycle actuator (21) which is operated by the user to distribute electrostatic energy from the power source (20) to the electrostatic emitters (71-73, 81-83) so that a predetermined quantity of germicidal fluid (50, 51) is directed from each electrostatic emitter (71-73, 81-83) towards each of the user's hands during the dispensing cycle. In one embodiment each hand is sprayed with an opposite charge. In another embodiment each hand is sprayed by multiple electrostatic emitters (71-83, 81-83) having opposite charges. In still another embodiment the electrostatic emitter (71-73, 81-83) directed at each hand is pulsed such that each pulse has an opposite charge. In yet another embodiment the user is grounded so that opposite charges are unnecessary.

Abstract: Known turn-to-turn windings with overlapping, sinuous conductor strands either only insufficiently use the slot space or are difficult to produce. In addition, no uniform distribution of the current intensity is achieved in the winding head space. The disclosed multiple-phase conductor layers are made of identical conductor strands located in the slot space at the same distance from the air gap surface. The conductor layers superimposed in the slots supplement each other in the use of the winding head space in that they lead the current in opposite directions across the width of the slot. A uniform distribution of the current intensity and a high space utilisation are achieved in that the layered winding heads are offset relative to the layers in the slot in the direction of the slot depth by half the height of a layer. Each conductor strand occupies two winding head layers when crossing the winding heads, the layers being exchanged at about the centre of the connection section at the outside of the winding heads. Alternating second conductor layers in succession are directly interconnected. Engines and generators equipped with space-optimised turn-to-turn windings are characterised by a high effectiveness and power density.

Granted: 2003-04-08
Abstract: A system and method for the automated maintenance of a computer system. A scheduler periodically activates sensors. When activated, the sensors gather  information about various aspects of the computer system. The sensors store this information in a knowledge database. The knowledge database also contai ns cases, questions, and actions. The cases describe potential computer problem s and solutions. The questions are used to diagnose the problems, while the actions describe steps that can be taken to solve the diagnosed problems. If  the information gathered by the sensors indicates a problem with the compute r system, then the sensors activate an artificial intelligence engine. The engine uses the information in the knowledge database to evaluate certain cases. If information necessary to evaluate a case is not in the knowledge database, then the engine activates a sensor to gather the information. As t he cases are evaluated, the confidence levels of certain other cases, questions , and actions increase. If the confidence level of a case or question rises above a predetermined threshold, then the engine evaluates that case or question. If the confidence level of an action rises above the threshold, th en that action represents the likely solution to the problem. Accordingly, the engine activatesa sensor to perform the action. If no case, question, or action rises above the threshold, then the knowledge database does not conta in enough information to solve the problem. In such a case, the engine saves th e state of the computer system and knowledge database. Then, a human expert ca n update the database with the knowledge necessary to solve the problem.</SDOA B>

Title: Toolboxes and tool cases with pivotable component holder
Inventor: VASUDEVA KAILASH C
IPC: B25H3/06
Filed: 1998-08-05
Granted: 2004-11-02
Abstract: A tool container, such as a toolbox or gift case, has at least one pivotable component holder (10) pivotally mounted therein for pivoting movement between a storage position and an access position. The pivotable component holders are biased towards the access position when the lid (2) is open.      The tool container brings an element (24) directly or indirectly into contact with at least one of the pivotable component holders to rotate it to the storage position when the lid closes, with no direct connection between the lid and the pivotable component holders. Where there are multiple pivotable component holders, they may be ganged together, for example via a gang bar (18).      Instead of rotation of the pivotable component holders being triggered by lid closure, such rotation could be triggered by removal or storage of the tool (88) for which the components are intended. Pivotable holder components may be manipulated manually between storage and access positions when the lid is open and movement may be independent of the lid position.

Abstract: Cette invention porte sur des gels hydrolytiquement dégradables de structures de poly(éthylène) glycol réticulées. L'ajout d'eau provoque le gonflement de ces structures réticulées qui se transforment en hydrogels. On peut préparer les hydrogels en faisant réagir deux dérivés différents de PEG contenant des fractions fonctionnelles aux extrémités de la chaîne qui réagissent entre elles de façon à former de nouvelles liaisons entre des chaînes polymères. On sélectionne les dérivés de PEG pour former dans la structure réticulée des liaisons covalentes hydrolytiquement dégradables. La dégradation hydrolytique peut produire la dissolution des composants du gel et la libération régulée des molécules piégées, y compris les médicaments. Il est possible d'éviter l'utilisation des réactifs autres que le PEG. Il est possible de réguler la vitesse de l'hydrolyse en faisant varier les atomes adjacents aux groupes fonctionnels hydrolytiquement dégradables de façon à effectuer une régulation précise de l'administration des médicaments in vivo.

Title: Thrust bearing
Inventor: FERGUSON JAMES HAROLD
IPC: F16C17/04
Filed: 2000-10-26
Granted: 2008-12-30
Abstract: A thrust bearing for a rotating machine has a rotating ring and a bearing shoe for use in a non-filled oil chamber that permits oil flow through the bearing shoe. The oil flows out a leading recessed groove in the bearing shoe and across the bearing shoe surface. This permits for the oil flow to cool the bearing shoe and maintain lubrication between the bearing shoe and the rotating ring. Further, the non-filled oil chamber acts more as an oil collection chamber which provides two distinct advantages. One advantage is a reduction in bearing losses not present due to the elimination of swirling of the oil bath. The other advantage is one of servicing by the ability to inspect the bearings and all oil conduit connections without being encumbered by oil partially covering or surrounding the bearing shoe. The thrust bearing has an oil reservoir located below the non-filled oil chamber into which oil drains from the non-filled oil chamber and an oil cooling and circulating system comprising a pump, heat exchanger and conduit connectors connected to each oil inlet for circulating oil drained into the oil reservoir through the heat exchanger into the flexible hoses and back into the bearing shoes. Further, the thrust bearing shoe has a secondary oil inlet adjacent the leading edge of the bearing shoe providing a safety back-up lubrication source.

Abstract: The profiled surface is used as an abradable (1) in flow machines. In these machines blade tips (2) move over the profiled abradable in a predetermined direction (v). In so doing they produce a partial surface, an abraded surface (10), which is formed by material ablation. The profiling of the surface is formed by ribs (15) which surround chamber-like depressions (11). A rib direction can in each case be associated with the ribs. The abradable (1) forms a pattern which is built up of strip-like elements (5) and the elements of which lie in the directions of the ribs on connection lines (45) between corner points (41, 42; 43, 44) of a reference grid (40). Largely at each location of the abraded surface (10) - i.e. at least at more than 80 - 95% of the abraded surface - the rib direction differs from the direction of movement (v) of the blade tips (2).   For at least two thirds of the abraded surface the direction of movement deviates from the rib direction by more than 30°, preferably more than 45°. The strip-like elements (5) of the abraded surface can be curved as well as discrete and/or partly connected strips.
