Patent number: 6294574Abstract: 2,5-Diaryl tetrahydrofurans, 2,5-diaryl tetrahydrothiophenes, 2,4-diaryl tetrahydrofurans, 2,4-diaryl tetrahydrothiophenes, 1,3-diaryl cyclopentanes, 2,4-diaryl pyrrolidines, and 2,5-diaryl pyrrolidines are disclosed that reduce the chemotaxis and respiratory burst leading to the formation of damaging oxygen radicals of polymorphonuclear leukocytes during an inflammatory or immune response. The compounds exhibit this biological activity by acting as PAF receptor antagonists, by inhibiting the enzyme 5-lipoxygenase, or by exhibiting dual activity, i. e., by acting as both a PAF receptor antagonist and inhibitor of 5-lipoxygenase. A method to treat disorders mediated by PAF or leukotrienes is also disclosed, that includes administering an effective amount of one or more of the above-identified compounds or a pharmaceutically acceptable salt thereof, optionally in a pharmaceutically acceptable carrier.Type: GrantFiled: June 6, 1995Date of Patent: September 25, 2001Assignee: Cytomed, Inc.Inventors: Xiong Cai, Sajjat Hussoin, San-Bao Hwang, David Killian, T.

Patent number: 5659987Abstract: A multi-portion label is provided which avoids the need for carbon paper type duplication. The label can therefore be printed on a single sheet of label material, using a laser printer or the like, instead of relying on impact printers or hand printing. The label includes a main portion which is fixed into place on a package surface or the like. The first portion is contiguous with a second portion which is characteristically folded under the first portion when the label is fixed in place. The first and second portions are, for example, manually separable, whereby the second portion can be withdrawn from underneath the first portion, and can serve as a proof of delivery receipt, or the like.Type: GrantFiled: June 26, 1995Date of Patent: August 26, 1997Assignee: Diskdeed Printing Technologies Pty. Ltd.Inventor: Wim Scheggetman

Patent number: 5660481Abstract: A hydrodynamic thrust, journal or combined radial and thrust bearing which may be mounted within a sealed housing assembly which can be, for example, be used to replace rolling element bearings. The bearing can be designed for mounting to either the shaft or housing. If mounted for rotation with the shaft, the bearing pads move relative to a smooth support surface. The bearing includes a bearing pad structure that may change shape and move in any direction (six degrees of freedom) to optimize formation of a converging wedge for hydrodynamic operation, equalization of load on the bearing pads in thrust bearings and to adjust for any shaft misalignment. The bearing pad may be formed so as to contact the shaft in the installed state and to deflect under fluid film pressure. The pad is separated from the support member by a support structure which includes one or more beam-like members. The support structure preferably includes a primary support portion, a secondary support portion and a tertiary support portion.Type: GrantFiled: November 24, 1993Date of Patent: August 26, 1997Inventor: Russell D.

Patent number: 5656563Abstract: A dense, self-sintered silicon carbide/carbon-graphite composite material and a process for producing the composite material is disclosed. The composite material comprises a silicon carbide matrix, between 2 and 30 percent by weight carbon-graphite, and small amounts of sintering aids such as boron and free carbon. The silicon carbide has an average grain size between 2 and 15 .mu.m, and the carbon-graphite has an average grain size between 10 and 75 .mu.m, the average grain size of the carbon-graphite being greater than the average grain size of the silicon-carbide. The composite material has a density of at least 80 percent of theoretical density as determined by the rule of mixtures for a composite material. This density is achieved with minimal microcracking at a high graphite loading with large graphite particles. The composite material exhibits good lubricity and wear characteristics, resulting in improved tribological performance.Type: GrantFiled: June 2, 1995Date of Patent: August 12, 1997Assignee: The Morgan Crucible Company plcInventors: Xin E. Chen, Mark E. Pfaff

Patent number: 5636710Abstract: Restaurants featuring improved efficiency through use of pneumatic systems for delivery of fast food products from a kitchen area to a food delivery area, such as in an out building, can revolutionize the fast food industry. A customer order entry station is located on a first side of the restaurant, and an order unit transmits order entry information to an indicator located adjacent to the kitchen area. A pneumatic dispatch station located adjacent to the kitchen area is connected via a second dispatch unit located in the food delivery area to a pneumatic tube. Upon the taking of a customer's order, the order entry information is acted upon by food service personnel who prepare food products such as sandwiches and load them into the kitchen area dispatch station for transport to the food delivery area. The food products reach the customer who has, by this time, navigated around the restaurant to the out building.Type: GrantFiled: September 15, 1995Date of Patent: June 10, 1997Assignee: Ace Food Services, Inc.Inventors: Charles L.
