Patent number: 5406878Abstract: Transmitting actuating forces from an actuator to a swashplate of an axial piston unit through a pin extending from a lever of the swashplate induces torsional stresses in the lever. The present invention overcomes this problem by securing a lever to a swashplate so that a distal end portion thereof extends into a slot of an actuator. The distal end portion has a cylindrical shaped surface pivotally seated in a mating socket formed in a slide block positioned within the actuator slot. The actuating forces transmitted from the actuator to the lever are thus transmitted in a straight line motion with minimal torsional stresses introduced into the lever.Type: GrantFiled: May 3, 1994Date of Patent: April 18, 1995Assignee: Caterpillar Inc.Inventors: Phillip L. Freeman, James C. Goade, Claude H. Werner

Patent number: 5407296Abstract: A one piece shaft clamp is disclosed having a flange and a tapered shank. The shaft clamp has a central bore that conforms in size and shape to the cress-sectional shape of a shaft. Relatively thin cuts are formed in the clamp through the shank and partially through the flange to form segments. Additional cuts are made in the flange adjacent the thin cuts to form relatively thin beams that resiliently interconnect the segments. The one piece shaft clamp is used in conjunction with a member that is to be secured to the shaft. The member has a tapered bore that mates with the tapered shank of the clamp so that when the shank is forced into the bore, the segments are urged into locking engagement with the shaft.Type: GrantFiled: May 7, 1993Date of Patent: April 18, 1995Assignee: The Whitaker CorporationInventor: Christopher K. Brown

Patent number: 5392594Abstract: An oxygenated organic liquid product and a fuel gas are produced from a portion of synthesis gas comprising hydrogen, carbon monoxide, carbon dioxide, and sulfur-containing compounds in a integrated feed treatment and catalytic reaction system. To prevent catalyst poisoning, the sulfur-containing compounds in the reactor feed are absorbed in a liquid comprising the reactor product, and the resulting sulfur-containing liquid is regenerated by stripping with untreated synthesis gas from the reactor. Stripping offgas is combined with the remaining synthesis gas to provide a fuel gas product. A portion of the regenerated liquid is used as makeup to the absorber and the remainder is withdrawn as a liquid product. The method is particularly useful for integration with a combined cycle coal gasification system utilizing a gas turbine for electric power generation.Type: GrantFiled: February 1, 1993Date of Patent: February 28, 1995Assignee: Air Products and Chemicals, Inc.Inventors: Robert B. Moore, William P. Hegarty, David W. Studer, Edward J. Tirados

Patent number: 5393207Abstract: A centrifugal blood pump features a pump assembly including a cylindrical barrel insertable into a motor stator. The barrel contains a motor rotor which is directly coupled to the pump's impeller. The barrel can be oriented and locked in the motor stator in many different angular orientations. Hemolysis is prevented in spite of high speed operation by reducing the clearance between the impeller and the impeller chamber, rounding the edges of the impeller blades, and providing a deflector to prevent blood from being impelled more than once around the impeller chamber periphery. An efficient releasable locking mechanism is also disclosed, as is a preferred method of assembling the pump assembly with close tolerances.Type: GrantFiled: January 21, 1993Date of Patent: February 28, 1995Assignee: Nimbus, Inc.Inventors: Timothy R. Maher, Pieter W. C. J. le Blanc, Lynn P. Taylor

Patent number: 5393206Abstract: A motor vehicle fuel pump including a tubular steel housing and a roller vane positive displacement pump and an electric motor in the tubular steel housing. The roller vane pump includes a pair of flat side plates, a rotor between the side plates, and a T-shaped sleeve bearing in a plain bore in one of the side plates. A lip at one end of a tubular body of the sleeve bearing has a side defining an annular seat in a plane perpendicular to the tubular body. The tubular body has a shaft bore therethrough and a stepped outer wall including a large diameter part adjacent the annular seat and a small diameter part adjacent the large diameter part. The large diameter part is force fitted in the plain bore until the annular seat engages flush against a flat, outside surface of the side plate. The annular seat positions the longitudinal centerline of the tubular body perpendicular to the outer side plate for optimum alignment with the armature shaft when an end of the latter is disposed in the shaft bore.Type: GrantFiled: June 29, 1994Date of Patent: February 28, 1995Assignee: General Motors CorporationInventors: Robert A. Roth, John G. Fischer
