Patent number: 7779818Abstract: A system and method is provided for automatically priming a fuel system by bleeding/purging air or vapor therefrom. The system includes a bleed valve configured to automatically move between three positions in response to the pressure of the fuel in the system. When fuel pressure is in a first pressure range, the bleed valve automatically moves to a first-closed position for preventing fuel from draining to the fuel tank and thereby drawing air into the fuel system. When the fuel pressure moves to a second, higher pressure range, the bleed valve automatically moves to an open position for bleeding air out of the fuel system and into the tank, thereby priming the fuel system. When the fuel pressure moves to a third, still higher pressure range, the bleed valve automatically moves to a second-closed position so as to not interfere with the regulation of the pressure regulating valve.Type: GrantFiled: February 6, 2008Date of Patent: August 24, 2010Assignee: Caterpillar Inc.Inventors: Douglas E. Wilson, Mark A. McElroy, John A. Ward, Nathan T. Kelly, Lloyd A. Hendrix

Patent number: 6279555Abstract: Air laden with oil and blow-by gases is evacuated from an engine compartment such as a crankcase. The air is cleaned by removing oil and may be reused for engine combustion by routing it through a turbocharger inlet. The reclaimed oil may be returned to an oil pan for reuse in engine lubrication.Type: GrantFiled: August 31, 2000Date of Patent: August 28, 2001Assignee: Caterpillar Inc.Inventors: Thomas J. Crowell, Douglas E. Wilson

Patent number: 5908207Abstract: The book holder is mounted on a stand. The book is held on the book holder by four clamps. Upper wooden post (24) is mounted on lower wooden post (25) and is free to rotate. As shown the wooden feet (26) and (27) are fastened to lower post (25) by means of the round steel nut (28), threaded stud (30), and wingnut (29). The stand can be quickly and easily assembled and dissassembled by one screw and wingnut holding it together. The wooden wingnut wrench shown is used to turn wingnut (29) and all other wingnuts on the book holder.Type: GrantFiled: April 14, 1997Date of Patent: June 1, 1999Assignee: Douglas E.

Patent number: 5553360Abstract: A wedge socket assembly having a wedge socket, a pin for connecting objects to the wedge socket, a wedge, and a bolt for holding the wedge in the wedge socket. The wedge socket has an elongated, hollow basket of substantially rectangular cross-section. The hollow basket has a large opening at a first end, a small opening at a second end, and an interior cross-section tapering from said large opening to said small opening. Connected to the basket are a pair of jaws extending from opposite sides of the first end, and the jaws each have an opening therethrough aligned with one another, with the pin inserted through the openings and retained by a cotter pin. The wedge has a first wedge portion with a large end and a small end, and is of substantially the same shape as the interior of the basket.Type: GrantFiled: May 19, 1995Date of Patent: September 10, 1996Assignee: The Crosby Group, Inc.Inventors: Charles E. Lucas, Douglas E. Wilson
