Patent number: 7810466Abstract: A compound bracket system (400) for an internal combustion engine (100) includes a first bracket (112) that is rigidly connected to a crankcase (102) of the internal combustion engine (100). The first bracket (112) forms at least one mounting pad (310) that is arranged to connect to and support a first engine component (114). A second bracket (120) is connected to the crankcase (102) through at least one additional engine component (110). The second bracket (120) forms a component cavity (208) that is arranged to accept and support a second engine component (118). The first bracket (112) forms an interconnection pad (314), and the second component forms a strut (216) having a mounting tab (218). The mounting tab (218) is advantageously connected to the interconnection tab (314) with a fastener (422), thus increasing the rigidity of the second bracket (120) as mounted on the engine (100).Type: GrantFiled: March 16, 2007Date of Patent: October 12, 2010Assignee: International Engine Intellectual Property Company, LLCInventors: Erich R.

Patent number: 5364439Abstract: An integrated system of non-condensable gas (NCG) and condensate treatment allows geothermal power plant condensate and non-condensable gas effluent streams containing H.sub.2 S and ammonia to be commercially useful for more than for cooling tower makeup. In the preferred embodiment, the pH of the condensate is increased by adding ammonia and the pH increased stream is contacted with NCG to scrub and oxidize the H.sub.2 S constituent of the NCG. By reducing the pH, the condensate or aqueous stream mixture can also be used to further transfer ammonia from the non-condensable gas stream to the aqueous stream, enriching the stream for use as a fertilizer/irrigation water mixture. If other commercial uses are desired for the mixture and/or oxidized NCG streams, they can be resin treated to remove the ammonia constituent. With the ammonia and H.sub.2 S constituents decreased, the condensate may be used for a variety of applications and the NCG can be injected or used as a commercial feed stream.Type: GrantFiled: April 29, 1992Date of Patent: November 15, 1994Assignee: Union Oil Company of CaliforniaInventors: Darrell L. Gallup, Kevin R. Kitz, Manuel E. Obando, Donald M. Fenton, Paul A. Peaden, Dennis L. Saunders, Brian J. Kelly

Patent number: 4932371Abstract: An engine control system is disclosed for reducing the hydrocarbon content in exhaust gas from a crankcase scavenged, two-stroke engine in the operating range near idle, with light operator induced engine loading. As operator demand for engine output power is increased, the control system increases the fuel per cylinder delivered to the engine, while restricting the supplied mass of air per cylinder to a value less than or equal to that flowing at unloaded engine idle.Type: GrantFiled: August 14, 1989Date of Patent: June 12, 1990Assignee: General Motors CorporationInventors: William C. Albertson, Donald M. Fenton, Paul E. Reinke, Steven D. Stiles

Patent number: 4496534Abstract: A method is provided for reconditioning a hydrogen sulfide removal system, such as a Stretford process system in which elemental sulfur is formed, after the system has become contaminated with sulfur-feeding bacteria to an extent that operation thereof is substantially impaired. The method includes adding a bactericide to the washing solution employed in the system to destroy the bacteria and adding a surfactant to the solution to remove dead bacteria from the surfaces of particulate sulfur formed in the system so that the particles can agglomerate in the intended manner to enable sulfur removal from the solution.Type: GrantFiled: December 6, 1982Date of Patent: January 29, 1985Assignee: Union Oil Company of CaliforniaInventors: Dennis D. Delaney, Donald M. Fenton
