Patent number: 7005064Abstract: A method and apparatus for remediating wastewater holding areas and the like includes a closed, foraminous dewatering membrane that is positioned adjacent to the wastewater holding area. Sludge and adjacent water on the bottom of the wastewater holding area are pumped in the form of a sludge slurry into the interior of the dewatering membrane. The water is removed from the sludge slurry by allowing gravitational forces to flow water through the dewatering membrane. The dewatering membrane is then opened, and the dewatered sludge is removed for depositing at an appropriate site.Type: GrantFiled: August 16, 2004Date of Patent: February 28, 2006Assignee: Infrastructure AlternativesInventors: Robert A. Keller, William J. Cretens, Kent T. Depuydt, Dana J. Trierweiler, Russell D. Johnson, Dean R. Wickoren

Patent number: 5967762Abstract: A turbocharger includes a main shaft carrying a turbine wheel and an impeller. The shaft is supported in a housing by means of a floating bearing and a ball bearing which is particularly effective in resisting axial loads tending to move the shaft toward the impeller. A preload spring positioned between the stationary race of the ball bearing and a thrust plate fixed to the housing provides a force urging said ball bearing against a shoulder on the main shaft against thrust forces tending to move the shaft toward the turbine wheel.Type: GrantFiled: March 14, 1997Date of Patent: October 19, 1999Assignee: Turbonetics, Inc.Inventors: Robert A. Keller, Hayden D. Austin

Patent number: 5456973Abstract: A monofilament which exhibits improved hydrolytic stability properties as compared to conventional polyester monofilaments is formed from the extrusion of a blend of PPS and at least one polymer selected from the group consisting of PET, a high temperature polyester resin and polyphenylene oxide and possibly, a hydrolytic stabilizing agent. The monofilament is produced without the inclusion of compatibilizers or fillers, even though PPS is known to be incompatible with PET and high temperature polyester resins in most applications. A fabric may be produced having increased resistance to hydrolytic degradation and includes a plurality of woven monofilaments, comprising a blend of PPS with at least one other polymer selected from the group consisting of PET, a high temperature polyester resin and polyphenylene oxide and, a hydrolytic stabilizing agent. Such fabrics have utility as fabrics for the dryer sections of paper machines. Methods for the production of such monofilaments are also provided.Type: GrantFiled: January 26, 1995Date of Patent: October 10, 1995Assignee: Shakespeare CompanyInventors: Larry E. Ballard, Michelle Diaz-Kotti, Robert A. Keller

Patent number: 4916999Abstract: A jack-up type of offshore oil-drilling platform is adapted for rocket launching, wherein the rocket is assembled on a mobile launch pad in a protected on-shore facility then loaded onto the floating jack-up barge for transport to a launch site miles offshore. The barge is jacked up to create a stable, sea-bottom supported structure; a particular feature is the used of a movable cantilever structure on which the rocket and its supporting pad are loaded while in the on-shore facility, then this structure is moved to a central location on the barge, the barge is floated, and the floating barge is towed to the launch site. At the launch site the structure is moved back to a cantilevered position for launch. In this manner the exhaust gasses from the rocket motors can be directed harmlessly into the sea.Type: GrantFiled: October 27, 1988Date of Patent: April 17, 1990Assignee: Rowan Companies, Inc.Inventors: C. R. Palmer, Robert A. Keller, Daniel F. McNease

Patent number: 3931712Abstract: This invention provides a differential pressure-activated control system having non-mechanical, remotely controllable, biasing means. The system comprises a differential pressure sensing means, having opposing first and second pressure sensing portions, a conduit between one portion of the sensing means and a system to be monitored and a second conduit means between a second portion of the pressure sensing means and the system to be monitored; the second conduit comprising in intermediate fluid flow pressure connection, a pressure regulator which limits the maximum pressure, in accordance with a desired predetermined pressure, conducted to the second portion of the pressure sensing means. Such pressure regulator can be remote from the system and from the pressure sensing means and is connected thereto only by non-moving, pressure-connecting means.Type: GrantFiled: October 15, 1974Date of Patent: January 13, 1976Assignee: The Echlin Manufacturing CompanyInventor: Robert A.
