Patent number: 11351489Abstract: A retrofit no filter no run insert for existing filtration systems manufactured without a no filter no run engine integrity protection feature. The insert is beneficial for a manufacturer that initially does not require the benefit of a no filter no run engine integrity protection feature but later requires such a feature. The insert can be installed into the existing filtration system without any modification to the existing filtration system head. The no filter no run insert prevents the equipment supplied by the filtration system (e.g., an internal combustion engine) from being operated without a filter element. Further, the no filter no run insert prevents the equipment supplied by the filtration system from being operated with an unauthorized or non-genuine replacement filter element. The no filter no run insert safeguards against damage to downstream components of the filtration system and malfunctions of equipment in which the filtration system is used.Type: GrantFiled: July 8, 2020Date of Patent: June 7, 2022Assignee: CUMMINS FILTRATION IP, INC.Inventors: Mark D.

Patent number: 11346093Abstract: Combined Sewer Overflow (CSO) events require certain minimum treatment, before discharge, according to EPA regulations. However, these events are infrequent, and CSO treatment systems remain idle most of the time. Tertiary filtration is typically used to polish off the secondary treated water in order to remove suspended matter, phosphorous, etc. Tertiary systems are usually designed to handle design flows and remain active most of the time. These are two independent unit operations requiring major capital investment and operational expense. According to this invention an interchangeable system is able to switch a tertiary treatment reactor back and forth between two applications ensuring seamless operation, smooth transition and significant cost savings for treatment facilities.Type: GrantFiled: November 21, 2018Date of Patent: May 31, 2022Assignee: Ovivo Inc.Inventors: Hiren Trivedi, Michael Snodgrass
