Abstract: This invention provides a graft delivery system and methods for its use comprising a prosthetic graft (12) secured to an expandable anchoring member, such as a stent (13), by a butt-joint attachment means (21 ) to minimize the system's profile. The delivery system employs a catheter (11) with a relatively small diameter shaft (14) for flexibility and a relatively large diameter (14) delivery base (17) for supporting expansion of the anchoring member. The butt-joint attachment mean s comprises any means suitable to secure the graft to the anchoring member when deployed within the patient's vasculature and allows t he anchoring member and graft to expand during deployment. In a preferred embodiment, the delivery system is configured so that the expansion of the anchoring member pulls the distal end of the graft over the proximal end of the anchoring member and the final expansion of the anchoring member seals the distal end of the graft (12) between the proximal end of the anchoring member and the vessel (20). O ne preferred method of use is to deploy a second anchoring member (31) coaxially within the already deployed first anchoring member and graft assembly, overlapping at least the distal end of the graft in order to further secure the graft and minimize flow by.

Title: Gas flow and lubrication of a scroll compressor
Inventor: SIMMONS BILL P
IPC: F04C29/02
Filed: 1996-01-30
Granted: 2001-05-29
Abstract: The flow, use, interaction and separation of lubricant and gas flowing through the suction pressure portion of a low-side refrigeration scroll compressor is managed by the use of a drive motor mounting sleeve and a multi-ported frame.  The mounting sleeve and frame provide for the direction of oil to surfaces within the low side of the compressor shell which require lubrication as well as the conduct of suction gas to the scroll compression mechanism in a manner which cools the compressor drive motor yet which maintains the respective flows of oil and suction gas sufficiently separate to ensure that excessive amounts of oil are not conducted out of the compressor in the gas which is compressed thereby. Lubrication is enhanced by the use of a vent passage which opens into a relatively lower pressure region within the suction pressure portion of the compressor shell. The vent induces lift and assists in the delivery of oil, upward and through a gallery in the compressor's drive shaft, to the various surfaces in the upper portion of the compressor which require lubrication.

Abstract: An optimistic distributed simulation method applicable to event-driven simulation that requires only a single rollback announcement per straggler message, with no need for other simulation processes to announce their roll backs. The method is accomplished by maintaining transitive dependency information between the simulation processes in the form of a simulation vector. The present invention eliminates the need for output queues and also the possibility of multiple roll backs per simulation process and avalanche of anti-messages. Alternatives to reduce blocking and minimize the size of the simulation vectors are also disclosed thereby reducing the overhead requirements for systems with large numbers of logical processes.
