Patent number: 11583790Abstract: An anti-counterfeiting mechanism for a filter element to specifically, and preferably uniquely, identify a filter with a conductive pattern or path of conductive materials preferably either embedded (thin film circuit) under the surface, or over molded on, a portion of the filter. The conductive materials are preferably positioned at the filter end cap. The resistance of the filter element is an identifier that is preferably associated with the OEM manufacturer's labeling (such as product number) and/or other branding of the component. This electrical resistance signature permits rapid identification of counterfeit filters.Type: GrantFiled: March 18, 2021Date of Patent: February 21, 2023Assignee: CUMMINS FILTRATION IP, INC.Inventors: Mark V. Holzmann, J. Bruce Schelkopf

Patent number: 9000611Abstract: One embodiment of the present application is directed to a protection technique for an electric power generation system. In one or more implementations, an electric power generator, generator control circuitry, electrical output sensors to provide one or more corresponding signals, electrical switching equipment to selectively couple the generator to an electrical load, and electric power feeder or branch circuit conductors, to route electric power from the generator to the switching equipment, are provided. The control circuitry is responsive to the sensor signals to determine if a shutdown condition exists as a function of a protection profile determined for the system. This profile may account for damage thresholds of the generator, the feeder or branch circuit conductors, the electrical switching equipment for each of a number of different combinations of level and duration of electrical output as represented by the sensor signals.Type: GrantFiled: April 20, 2009Date of Patent: April 7, 2015Assignee: Cummins Power Generation IP, Inc.Inventors: Rick A. Lorenz, J. Bruce Schelkopf

Patent number: 8852443Abstract: Various “no filter, no run” fuel filtration designs are described that include a variable restriction orifice (VRO) designed to vary the amount of fluid, for example fuel, that reaches a fluid outlet. The VRO has a fully open position at which a maximum non-zero fluid flow is permitted, and a fully closed position at which a limited amount of fluid can flow to the outlet. In the case of diesel fuel, the amount of fuel flow permitted at the fully closed position provides lubrication of downstream fuel system components, for example the fuel pump, but is insufficient to permit engine operation.Type: GrantFiled: September 12, 2007Date of Patent: October 7, 2014Assignee: Cummins Filtration IP, Inc.Inventors: Todd Forrest, J. Bruce Schelkopf, Ted S. Loftis, Barry Verdegan, Wassem Abdalla, Mark Wieczorek, Gérard Malgorn, Charles W. Hawkins, Chad Thomas, Joe Saxon, Mark Johnson, Naren Shaam

Patent number: 8105484Abstract: According to one representative embodiment, a fluid storage device for storing a first fluid in a second fluid storage container fillable with a second fluid includes a first fluid storage container, a first fluid inlet coupled to the first fluid storage container, and a first fluid outlet coupled to the first fluid storage container. The first fluid storage container is flexible. The first fluid inlet is communicable in fluid receiving communication with a first fluid source. The first fluid in the first fluid storage container is caused to drain from the first fluid outlet based on at least one of a first fluid level, a first fluid storage container pressure, a second fluid storage container pressure, the second fluid storage container filling with the second fluid, the first fluid outlet being opened for first fluid egress, and a first fluid outlet pressure.Type: GrantFiled: December 19, 2008Date of Patent: January 31, 2012Assignee: Cummins Filtration IP, Inc.Inventors: Gerard Malgorn, Arnaud Le Ven, Emmanuel Page, Jean-Yves Picard, J.
