Patent number: 10094702Abstract: A weight determining system is for use with non-singulated and non-spaced arrangements of items on a conveyor system. The system includes an array of load cells, a scanning apparatus, and processors. Each of the items bears upon one or more of the load cells. Each of the load cells bears one or more of the items, and generates load data associated with them. The scanning apparatus generates scan data for the arrangements of the items on the conveyor. Based on the scan data, the processors: apportion the load data from each load cell to the items bearing on it; allocate to each item the load data apportioned from the various load cells; and determine a weight for each item. Also disclosed are a corresponding weight determining method, as well as a computer readable medium containing executable instructions to encode the processors to perform as aforesaid.Type: GrantFiled: September 28, 2015Date of Patent: October 9, 2018Assignee: PUROLATOR INC.Inventors: James Cameron Laird, Andrew Silerio Vicencio, Kirk Edward Serjeantson, Theodore Pribytkov

Patent number: 9095795Abstract: An anti-drainback valve contains a locking mechanism for securing the valve into to a filter assembly. The locking mechanism is made up of at least two keys that extend from the valve into beyond a cap of the filter assembly in order to secure the valve within the filter assembly. When multiple keys are employed, such keys may be equally spaced around the circumference of the cap. Manufacturing costs are kept minimal as minimal material is required and a two part mold may be employed during manufacturing.Type: GrantFiled: February 27, 2008Date of Patent: August 4, 2015Assignee: MANN+HUMMEL Purolator Filters LLCInventors: Rajan Ahuja, L.

Publication number: 20150129470Abstract: A fluid filter includes a filtering medium and a relief valve. The relief valve includes an opening and is disposed between opposite longitudinal ends of the filtering medium. The filtering medium may include a plurality of pleats, and the relief valve may couple planar surfaces of two pleats. The opening of the relief valve may be directly connected to an outlet of the fluid filter, so that flow of fluid through the opening bypasses the filtering medium.Type: ApplicationFiled: November 13, 2013Publication date: May 14, 2015Applicant: Mann+Hummel Purolator Filters LLCInventor: Timothy A.

Patent number: 8943997Abstract: An apparatus for transferring adhesive material to portions of filter elements that are displaced relative to the apparatus includes a dispenser from which heated adhesive material is discharged, a transfer arrangement that receives discharged adhesive material and transfers the discharged adhesive material to the portions of the elements as they are displaced, and a cooling arrangement. The cooling arrangement cooperates with the transfer arrangement to cool the discharged adhesive material while the adhesive material is carried by the transfer arrangement to the adhesive material receiving portions of the elements. A process by which adhesive material is transferred to adhesive material receiving portions of the filter elements, as well as an air line panel filter produced by that process, are also discussed.Type: GrantFiled: December 12, 2007Date of Patent: February 3, 2015Assignee: Mann+Hummel Purolator Filters LLCInventor: James Steven Whitehurst

Patent number: 8918205Abstract: An adjustable speed control system includes a reader, databases, processors and a conveyor controller. The databases store data concerning conveyor stops and failed attempts by the reader to identify conveyed items. Based on the failed attempts and the conveyor stops, the processors calculate an optimal speed of the conveyor. The controller adjusts the conveyor speed towards the optimal speed to increase the conveyed items successfully identified by the reader. Also disclosed are a corresponding method and computer readable medium on which is stored instructions to, upon execution, adjustably control the conveyor speed.Type: GrantFiled: December 2, 2011Date of Patent: December 23, 2014Assignee: Purolator Inc.Inventors: Kirk Edward Serjeantson, Andrew Silerio Vicencio, Cameron James Laird, Adam Stevenson

Patent number: 8652327Abstract: A fluid filter providing several degrees of filtering is designed to be receivable in a filter container that is closable by a cover. The filter itself includes both an annular main filter element, through which fluid to be filtered can pass radially to undergo primary filtration, and a supplemental filter element, to which fluid discharged from the main filter element passes to provide supplemental filtration additional to the primary filtration. The main filter element, the supplemental filter element, or both may be oblong or circular in cross section. At least one of a pair of end caps disposed on opposed ends of the main filter element carries the supplemental filter element as well as one end of the main filter element. That end cap may or may not be permanently secured to the one filter element end.Type: GrantFiled: September 14, 2010Date of Patent: February 18, 2014Assignee: MANN+HUMMEL Purolator Filters LLCInventor: Daniel Lucas
