Patent number: 11612841Abstract: A sensing system for detecting degradation of a machine fluid is disclosed. The sensing system may comprise a tag having electrical contacts. The tag may be configured to transmit a wireless signal when the electrical contacts are in electrical communication. The sensing system may further comprise a dissolvable element separating the electrical contacts and obstructing electrical communication between the electrical contacts. The dissolvable element may be configured to dissolve and allow electrical communication between the electrical contacts when an acid content of the machine fluid reaches a level indicative of the degradation of the machine fluid.Type: GrantFiled: June 18, 2021Date of Patent: March 28, 2023Assignee: Caterpillar Inc.Inventors: Philip C. Spengler, Jeffrey R. Ries, Hind Abi-Akar

Patent number: 7383806Abstract: Carbon deposits on engine components can negatively affect engine performance. An engine of the present disclosure includes at least one carbon deposit resistant engine component attached to an engine housing. The engine component includes at least one relatively high surface tension surface that is a non-contact wear surface and to which a relatively low surface tension coating is attached. The relatively low surface tension coating has a surface tension at least one of equal to and less than 30 dyne/cm.Type: GrantFiled: May 18, 2005Date of Patent: June 10, 2008Assignee: Caterpillar Inc.Inventors: Hind Abi-Akar, Xiangyang Jiang, Jorge R.

Publication number: 20060124283Abstract: Inlet surfaces of a fluid-handling apparatus, such as a heat exchanger, are often prone to corrosion and erosion due to the high velocities of incoming fluid. The present disclosure includes a fluid-handling apparatus with a plurality of wetted surfaces of which a first portion is corrosion-erosion prone and a second portion is non-corrosion-erosion prone. The first portion is coated with a corrosion-erosion coating that is harder than the first portion. Less than all of the wetted surfaces are coated.Type: ApplicationFiled: December 14, 2004Publication date: June 15, 2006Inventors: Hind Abi-Akar, Chris Scolton

Publication number: 20060021303Abstract: An electrical connection element for providing an electrical connection to a porous material may include a first electrically conductive plate disposed on at least a portion of a first side of the porous material. A second electrically conductive plate may be disposed on at least a portion of a second side of the porous material, opposite to the first side. An electrically conductive material may impregnate the porous material in a region between the first and second electrically conductive plates, and an electrical connector may be attached to at least one of the first and second electrically conductive plates.Type: ApplicationFiled: July 30, 2004Publication date: February 2, 2006Inventors: Matthew Williams, Matthew Kiser, Michael Pollard, Jo Costura, Cornelius Opris, Hind Abi-Akar, Robert Meyer
