Patent number: 10000996Abstract: A flow device includes a flow-through region comprising at least one stage having a pocket configured to create a first pressure drop across the flow-through region in response to flow through the flow-through region in a first direction and a second pressure drop in response to flow through the flow-through region in a second direction. The first pressure drop is less than the second pressure drop under the same flow rates. The flow device has no moving parts to create the difference in pressure drop between the first direction and the second direction, the pocket has a larger cross sectional flow area than a first opening and a second opening fluidically connected to the pocket and a baffle positioned within the pocket having a āUā shape with a concave side of the baffle facing toward the second opening.Type: GrantFiled: April 30, 2015Date of Patent: June 19, 2018Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Ronnie D. Russell, Elmer Richard Peterson

Patent number: 7467664Abstract: A material that reacts to produced hydrocarbons acts as a latch to retain a stored potential energy force. In a specific application, a sliding sleeve valve is held away from a circulating port to allow drilling mud to be circulated out. Later, when the well is put on production, the lock that holds collets in a groove releases as exposure to produced hydrocarbons at a retaining sleeve makes it get soft. This, in turn, allows a spring force to run the collets out of their groove and straddle the circulation port between two o-rings on the shifting sleeve to close the port. The closure of the port directs produced hydrocarbons to screens that had been bypassed when mud was circulated out due to ports being the path of least resistance.Type: GrantFiled: December 22, 2006Date of Patent: December 23, 2008Assignee: Baker Hughes IncorporatedInventors: Travis E. Cochran, Jason M. Visosky, Elmer Richard Peterson

Patent number: 6409219Abstract: A system for preferable use in gravel packing is disclosed which includes a plurality of transport tubes which are mounted outside of gravel pack screens. The multiplicity of shunt tubes cover a particular zone so that the tubes have a varying length to deposit gravel at different portions of the zone. The tops of the tubes are preferably sealed until ready for use and activated by applied pressure. In the preferred embodiment, rupture discs are found at the tops of each of the tubes, set for different pressures so as to open up the transport tubes to the lower most portion of a particular zone and later in sequence to the higher-most portion. The transport tubes are affixed to each section of pipe and are made up when two sections of pipe are made up to alignment marks. When the marks are aligned, the transport tube segments from each pipe section are in an aligned and sealed relation while the tool joint is properly torqued.Type: GrantFiled: November 12, 1999Date of Patent: June 25, 2002Assignee: Baker Hughes IncorporatedInventors: Todd Broome, Benn Voll, Perry Douglas Baycroft, Elmer Richard Peterson, Bobby Edward Hall

Patent number: 4736643Abstract: A blocked jaw clutch assembly (156) having a second positive stop member (200,202) to limit axial movement of a second jaw clutch member (116) away from the first stop member (134) is provided. During initiation of a shifting operation, if the first (164) and second (116) jaw clutch members are not at substantially synchronous rotation, the second stop member will limit axial movement of said first jaw clutch member (108, 164) to a preselect position (FIG. 9B) axially intermediate the neutral axial position (FIG. 9A) and fully engaged axial position (FIG. 9C) thereof.Type: GrantFiled: March 7, 1986Date of Patent: April 12, 1988Assignee: Eaton CorporationInventor: Elmer A.

Patent number: 4735109Abstract: A compound change gear semi-blocked transmission (10) of the splitter type is provided. The transmission comprises a multi-speed main section (12) connected in series with an multi-speed auxiliary section (14). The main section utilizes manually engaged, non-blocked, nonsynchronized jaw clutch assemblies (56, 58, 60) while the auxiliary section utilizes resiliently shifted blocked jaw clutch assemblies (114, 116, 118, 120). The blocked jaw clutch assemblies are provided with ramps (176, 178, 180, 182) which will cause unblocking during a clutching operation if the main section is not engaged.Type: GrantFiled: July 22, 1987Date of Patent: April 5, 1988Assignee: Eaton CorporationInventors: Elmer A. Richards, Russell C. Holmes

Patent number: 4527447Abstract: An automatic mechanical change gear transmission system (10) is provided. The transmisssion (12) is a splitter type comprising a main section (48) connected in series with a blocked splitter type auxiliary section (50). The auxiliary section blockers (172) and clutch members (164) are provided with ramps (218, 220, 222, 224) which will tend to align the blockers and ramps in a nonblocking condition under the influence of biasing spring (178) if the main section is in neutral. A control unit (38) receives input signals and commands transmission shifts in a sequence including shifting the main section into neutral and shifting the auxiliary section to a new ratio during each shift procedure.Type: GrantFiled: December 6, 1982Date of Patent: July 9, 1985Assignee: Eaton CorporationInventor: Elmer A.
