Title: Preparation of pre-coated aluminum alloy articles
Inventor: KEENER STEVEN G
IPC: B32B15/08
Filed: 1996-05-01
Granted: 2008-01-08
Abstract: An aluminum-alloy article such as a fastener or rivet (40) is prepared by providing an aluminum-alloy article precursor that is not in its final heat-treated state, and in one form is in its solution treated/annealed state. A curable organic coating material is also provided. The method includes anodizing the article precursor, preferably in chromic acid solution and without chemical sealing during anodizing, applying the organic coating material to the aluminum-allo y article precursor, and precipitation heat-treating the coated aluminum article precursor to its final heat-treated state, thereby simultaneously curing the organic coating. If the aluminum alloy temper is of the naturally aging type, it is optionally lightly deformed prior to precipitation treatment aging. The approach may also be applied to articles that are not solution treated/annealed and aged, by first overly deforming the article precursor so that the curing treatment of the coating also partially anneals the article precursor to the final desired deformation state.

Title: Water management system for solid polymer electrolyte fuel cell power plants
Inventor: SCHEFFLER GLENN W
IPC: H01M8/04
Filed: 1996-06-25
Granted: 2001-11-27
Abstract: A simplified solid polymer electrolyte fuel cell power plant utilizes porous conductive separator plates having central passages which are filled with circulating coolant water. The coolant water passes through a heat exchanger which rejects heat generated in the power plant. Water appearing on the cathode side of each cell membrane is pumped into the water circulation passages through the porous oxidant reactant flow field plates by a positive .DELTA.P created between the cathode reactant flow field of each cell and the coolant water circulation passages between each cell. In order to create the desired .DELTA.P, at least one of the reactant gas streams will be referenced to the coolant water loop so as to create a coolant loop pressure which is less than the referenced reactant gas stream pressure. Excess water is removed from the coolant water stream. The system can operate at ambient or at elevated pressures. Each cell in the power plant is individually cooled on demand, and the power plant does not require a separate cooling section or reactant stream humidifying devices.

Granted: 2007-10-30
Abstract: The device is used for rolling an edge of a dough piece. It comprises a first mechanism for making a friction engagement with the edge of the dough piece and a second mechanism for moving the first mechanism inwards relative to the edge of the dough piece so that the edge is forced to roll on itself. For instance, this can be realised by a first plate having a plurality of elongated guiding slots. A plurality of followers are slidably mounted in corresponding slots of the first plate. A dough-engaging finger is connected to each follower. The fingers are located under the first plate and moved relative to the dough piece. The device mechanically rolls the edge or edges of a dough piece to form an elevated peripheral portion that prevents the toppings from falling or flowing out of the dough piece during the preparation or when cooked and served by the customers. It also gives a better appearance to the final products. The device may be used in an industrial food preparation process and replaces the manual forming of the elevated peripheral portion that required a large number of persons. It resolves the problem of having large quality variations from one dough piece to another, since the final result of the manual rolling operation depended in most part on the skills and concentration of each individual.

Title: Prioritized transaction server allocation
Inventor: DONAGHUE NORMAN J JR
IPC: H04Q3/64
Filed: 1999-03-05
Granted: 2006-01-24
Abstract: A facility for distributing transaction servers to process transactions of a number of different types is provided. The transaction types are organized into two or more priority levels ordered from highest to lowest. Each priority level has one or more transaction types. In the facility, a service level goal attribution system attributes a service level goal to each transaction type reflecting the level of service sought for transactions of the transaction type. An identification subsystem identifies transaction servers when they become available to process transactions. In response to each transaction server identified by the identification subsystem, a transaction server distribution subsystem assigns the identified transaction server to process a transaction of a type that needs an additional transaction server to meet its service level goal, and whose priority level is at least as high as that of any other transaction types that need an additional transaction server to meet its service level goal. When the assigned transaction servers complete processing of the transactions to which they are assigned, the identification subsystem reidentifies these transaction servers as again being available to process transactions.

Abstract: A personal floatation device comprises a wide buoyant collar hinged to a thoracic float. The collar has a front portion projecting forwardly under the chin of the wearer to cooperate with the thoracic float to limit forward tilting movements of the wearer's head. The hinge between the collar and the thoracic floater provides for the combination of the buoyancy of the collar and the thoracic float when a wearer fall face down in the water.      The juxtaposition of the collar and the thoracic float contributes to rapidly pivot the wearer's head out of the water. A buoyant flap is articulated to a rear end of the collar so as to be only responsive to backward movements of the wearer's upper body.

Abstract: A syntactical representation is used to generate data describing a hierarchical broadband network and relationships between its elements. The format of the syntactical representation resembles logic programming language clauses. The syntactical representation is used to specify a broadband connection problem to be solved. Data describing physical resources and functionality of a set of network elements is entered into an inference engine which applies an algorithm to its input in order to find a solution to a specified connections planning problem. The algorithm is recursive and uses artificial intelligence techniques such as first fail, hierarchical planning and hill-climbing to guide the inference engine's search for a solution.
