Patent number: 10036386Abstract: A scroll compressor includes one or more stage of compression disposed within a compressor housing. One or more of the stages includes a stationary scroll member including a base and a generally spiral wrap extending from the base of the stationary scroll member. One or more of the stages further includes an orbiting, scroll member including a substantially circular base and a substantially spiral wrap extending from the base of the orbiting scroll member. A coupling is disposed between the first scroll member base and the second scroll member base and in surrounding relationship to the first and second scroll member spiral wraps. At least one stabilizing pad is disposed between the first scroll member base and the second scroll member base and in axial thrust force relationship with the coupling to at least partially prevent tipping of the second scroll member.Type: GrantFiled: July 31, 2014Date of Patent: July 31, 2018Assignee: TRANE INTERNATIONAL INC.Inventors: Scott Joseph Smerud, John Robert Sauls, Michael Gerard Benco, Jerry Allen Rood, Rodney Lakowske

Patent number: 9816506Abstract: An oil lubrication system for a multi-stage compressor separates oil from a refrigerant at an intermediate pressure following the first stage of compression and then routes the separated oil at the intermediate pressure to the compressor suction cavity bearings at the intermediate pressure, thus avoiding further compression of oil in subsequent stages of compression. The efficiency of the multi-stage compressor can be increased by not raising the pressure of the oil through the subsequent stages of compression.Type: GrantFiled: July 31, 2014Date of Patent: November 14, 2017Assignee: TRANE INTERNATIONAL INC.Inventors: Jerry Allen Rood, Michael Gerard Benco, Scott Joseph Smerud, John Robert Sauls, Rodney Lakowske

Patent number: 9784376Abstract: A valve assembly for a compressor includes a flow passage defining an inlet, an outlet, and a valve seat located proximate the inlet. The valve assembly also has a valve member that includes a head portion engageable with the valve seat. The head portion has a front face, a rear face located closer to the outlet than the front face, and a side face extending between the front and rear faces. The head portion further has a first convex curvature formed between the front face and the side face. The valve member also includes a collar portion extending toward the outlet from the rear face of the head portion.Type: GrantFiled: July 16, 2014Date of Patent: October 10, 2017Assignee: TRANE INTERNATIONAL INC.Inventors: Yahia Abdelhamid, Scott Joseph Smerud, Scott Michael Branch, John Robert Sauls

Patent number: 9657737Abstract: A scroll compressor includes an orbiting scroll member disposed within a compressor housing. The orbiting scroll member has a substantially circular baseplate and a generally spiral wrap extending from its base. A first seal is disposed proximal to the outer periphery of the orbiting scroll baseplate to provide an external seal between the baseplate and the housing. A second seal is disposed radially inward from the first seal to provide an internal seal between the baseplate and the housing. A space between the internal seal and the external seal defines a balance piston chamber. The balance piston chamber is pressurized via a high or intermediate pressure oil source to reduce thrust loading on the baseplate caused by an axial pressure differential across the baseplate.Type: GrantFiled: July 31, 2014Date of Patent: May 23, 2017Assignee: TRANE INTERNATIONAL INC.Inventors: Scott Joseph Smerud, John Robert Sauls, Michael Gerard Benco, Jerry Allen Rood, Keith Adam Novak, Derrick Lepak, Joseph M. Heger

Patent number: 7674301Abstract: Yarns and fabrics formed from such yarns incorporating an arrangement of discrete zones of variable heat treat history thereby imparting differential dye affinity and structural character at discrete zones along the yarn length are described. The differential dye affinity permits variable shading along the yarn length when the yarn is subjected to a dye bath. Processes and equipment for manufacturing such yarns are also provided.Type: GrantFiled: July 5, 2005Date of Patent: March 9, 2010Inventors: Robert Saul Brown, William M Pascoe

Publication number: 20050245360Abstract: A system and method for simulating a swimming stroke wherein the resistance is supplied by resilient members connected to the user's arms and legs. In one aspect the invention is an exercise system comprising: a bench for supporting a user; means for securing to the user's left arm; means for securing to the user's right arm; means for securing to the user's left leg; means for securing to the user's right leg; and each of the left arm securing means, the right arm securing means, the left leg securing means, and the right leg securing means connected to the bench by at least one resilient member. Preferably the resilient members are connected to a pair of specially adapted gloves and socks. In another aspect, the invention is a method of using the system to simulate a swimming stroke wherein the user's movement is resisted during the entire range of motion.Type: ApplicationFiled: May 3, 2004Publication date: November 3, 2005Inventor: Robert Saul

Patent number: 6364409Abstract: A folding chair includes collapsible rungs in a backrest and seat permitting folding in two directions. Stability is further enhanced by the upholstery which further forces the top rung of the chair downward and the center rung rearward, making the chair rigid in the open position. Siderails and back supports slide freely along the chair's rear legs creating a folding mechanism that folds the seat upwards while also pulling the rear leg upwards in the same direction resulting in greater stability without increasing the height of the folded package.Type: GrantFiled: February 18, 2000Date of Patent: April 2, 2002Assignee: The Coleman Company, Inc.Inventors: Jonathan Robert Saul, Duane Michael Perpich, David Emil Harnadek, David Richard Collins
