Patent number: 11920677Abstract: A system including a gearbox and a hydraulic machine connected by a working fluid circuit. The gearbox including a gearbox housing having first and second gearbox fluid passages integrated into the gearbox housing. The hydraulic machine including a case having first and second hydraulic machine fluid passages, the first and second hydraulic machine fluid passages being integrated into the case. A set of rotating elements enclosed within the case. The first gearbox fluid passage and the first hydraulic machine fluid passage align to form a feed passage to conduct fluid at a first pressure from a first source to the set of rotating elements. The second gearbox fluid passage and the second hydraulic machine fluid passage align to form a charge passage to conduct fluid at a second pressure from a second source to the set of rotating elements. The first pressure being less than the second pressure.Type: GrantFiled: February 1, 2022Date of Patent: March 5, 2024Assignee: Caterpillar Inc.Inventors: Christopher W. Pruess, Aaron B. Crabtree, Jeremiah C Johnson

Publication number: 20130227834Abstract: An electric power generation device includes a genset with an engine coupled to a generator and an enclosure that includes a base having a plurality of bosses protruding upwardly each a respective predetermined height from a surface of the base. A plurality of coil springs is positioned between an upper surface of each of the bosses and a respective mounting member of the genset. The bosses and the mounting members are positioned such that each respective coil spring is approximately equally loaded by the genset.Type: ApplicationFiled: April 8, 2013Publication date: September 5, 2013Applicant: Cummins Power Generation IP, Inc.Inventors: Eric L. Nordstrom, Aaron C. Johnson, Peter G. Van de Walker

Patent number: 8413642Abstract: A genset engine that operates on an open loop EFI system and runs on gaseous fuels is described. The integration of various air sensors, including for example a manifold air temperature (MAT) sensor, a manifold absolute pressure (MAP) sensor, or an air flow sensor(s), can provide optimal engine performance when using gaseous fuels and when starting from a cold state. The sensors employed send data to the electronic control unit (ECU) and such data is used to determine the optimal air-to-fuel ratio (AFR). The ECU actuates the injector and the injector sends the requested amount of gaseous fuel to mix with the air flow to be combusted. This provides the engine with a gaseous fuel and air mixture that is at the requested relative AFR and the engine is able to start and meet performance.Type: GrantFiled: January 28, 2010Date of Patent: April 9, 2013Assignee: Cummins Power Generation, Inc.Inventors: Aaron C. Johnson, Keith M. Schorr, Timothy J. Krattenmaker

Patent number: 8366430Abstract: An improved safety device for a blow molding apparatus is disclosed. The safety device allows the user to trigger or disarm the locking mechanism and return the locking pins to the safe position instead of leaving it in the loaded position. The safety device prevents potential damage to an individual that is accessing the blow molding apparatus.Type: GrantFiled: February 18, 2010Date of Patent: February 5, 2013Assignee: Graham Packaging Company, L.P.Inventors: Aaron C. Johnson, Philip Mutarelli

Patent number: 8115928Abstract: A box inspector for detecting at an inspection station an unacceptable skew in, an item missing from, and/or an unacceptable gap in a box. The box inspector has pairs of aligned emitters and receivers generating a signal when an unacceptable skew is detected, at least two item present sensors corresponding to the number of items adapted to be located in a single row within the box and generating an item absent signal when an item is missing from the box, a gap detect sensor generating an unacceptable gap signal when the gap is larger than a predetermined gap size, and a box present sensor generating a box present signal when a box arrives at the inspection station. A controller receives signals from these components and generates indications when the box is unacceptably skewed, an item is missing from the box, and/or an unacceptable gap exists in the box.Type: GrantFiled: August 20, 2009Date of Patent: February 14, 2012Assignee: Graham Packaging Company, L.P.Inventors: Aaron C. Johnson, Philip Mutarelli

Publication number: 20110179779Abstract: An exhaust system that can improve emissions treatment by reducing certain emissions species. The exhaust system draws air into the exhaust system from an air source, when exhaust pressure decreases to a threshold so that air can enter the exhaust system. The exhaust system is in a genset engine. The air source is a pressurized air source, such as an existing fan of the genset engine. A portion of the air generated by the air source is pulled off so that it flows directly toward the exhaust system, using a one-way valve and conduit that fluidly connects the air source to the exhaust system.Type: ApplicationFiled: January 28, 2010Publication date: July 28, 2011Applicant: CUMMINS POWER GENERATION, INC.Inventors: David T. Falkowski, Deborah A. Klinkert, Luke R. Staples, Jeffrey D. Peterson, Steven M. Swanson, Shimkiri S. Syiem, Michael J. Turbak, Aaron C. Johnson
