Title: Method and apparatus for managing relationships among objects in a distributed object environment
Inventor: MARTIN BRUCE E
IPC: G06F9/44
Filed: 1996-03-20
Abstract: A method and apparatus for managing relationships among objects in a distributed object environment includes a method and apparatus for determining whether two or more object references refer to identical objects; a method and apparatus for providing a unique identifier for an object; a method and apparatus for checking role types for the formation of relationships; and a method and apparatus for caching role and object locations in roles in a relationship. In the method and apparatus for determining whether two or more object references refer to the same object, a unique object identifier is compared to determine if the objects referred to by the object references are identical. The unique identifier is provided by concatenating information identifying the machine address of the process that created the object in addition to the process ID, the time of creation and a process counter. In the method and apparatus for checking role types, information including the number of roles and is passed to a relationship factory which determines whether the number, types and cardinality of the roles passed to the factory are consistent with the relationship object to be created. The method and apparatus also includes caching of object references and roles for objects related to a given object in that object's role. The methods and apparatus of the invention thus provide valuable tools for managing relationship among objects in a distributed object environment efficiently.

Abstract: Le moteur à explosion avec des pistons rotatifs a dans sa boîtier plusieurs cavités hébergeant chacune un piston rotatif d'une forme spéciale. Des doubles-manivelles chacune ayant la longueur variable relient entre eux les pistons rotatifs deux par deux. Le couple moteur cumulé de tous les pistons rotatifs est transmis à l'arbre moteur par l'inermédiaire d'une manivelle de longueur variable dont il est relié. Chaque piston rotatif tourne librement dans sa cavité en combinant le mouvement de glissage avec le mouvement de roulement ainsi que, comme résultat, à chaque rotation complète du piston rotatif l'arbre moteur exécute trois rotations complètes en sens inverse sans utilisé dans ce but des pignons ou d'autres mécanismes. Ce moteur a un petit gabarit par rapport à d'autres moteurs de même capacité, un petit nombre de pièces en mouvement, un bon rendement de conversion de l'énergie et un bon équilibrage. Il offre la possibilité d'avoir beaucoup de ses pièces fabriquées en matériaux céramiques ou métalo-ceramiques.

Inventor: COLLE KARLA SCHALL
IPC: F17D1/16
Filed: 1995-09-05
Abstract: A method for inhibiting the formation of clathrate hydrates in a fluid having hydrate forming constituents is disclosed. More specifically, the method can be used in treating a petroleum fluid stream such as natural gas conveyed in a pipe to inhibit the formation of a hydrate restriction in the pipe. The hydrate inhibitors used for practicing the method are substantially water soluble polymers formed from a cyclic imino ether. Such polymers may be ring closed cyclic imino ether ("CIE") polymers, ring opened CIE polymers, or combinations thereof. Some examples of ring opened CIE polymers include various N-acyl polyalkyleneimines produced by cationic polymerization, such as N-acyl substituted polyethyleneimine, N-acyl substituted polypropyleneimine, N-acyl substituted polybutyleneimine, N-acyl substituted polypentyleneimine and copolymers thereof. Ring closed CIE polymers may be derived from free radical or anionic polymerization of 2-alkenyl-2-oxazolines, 2-alkenyl-2-oxazines, and other cyclic imino ethers having an alkene functional group. Also, such ring closed and ring opened CIE polymers can be copolymerized with other substantially water soluble polymers or used in various ratios with other substantially water soluble polymers and copolymers. Preferably, a solvent such as water, brine, alcohol, or mixtures thereof is used to produce an inhibitor solution or mixture to facilitate treatment of the petroleum fluid stream.
