Patent number: 10233072Abstract: A diesel exhaust fluid system for use on a diesel-powered machine, including a storage tank adapted to store diesel exhaust fluid, a receiver, and a shut-off valve. The receiver is disposed in selective fluid communication with the storage tank and is adapted to receive diesel exhaust fluid. The shut-off valve is interposed in fluid communication between the storage tank and the receiver and has: a first position wherein diesel exhaust fluid can flow from the receiver to the storage tank, and a second position wherein flow is interrupted from the receiver to the storage tank. The shut-off valve moves from the first position to the second position in response to predetermined accumulation of diesel exhaust fluid in the storage tank.Type: GrantFiled: March 4, 2015Date of Patent: March 19, 2019Assignee: Benecor, Inc.Inventors: Brendan J. Foster, Hendrik F. Stoltz

Patent number: 8847105Abstract: A laser welding pressure unit comprises a housing, a rotating element, and a foot. The housing may attach to a laser head. The rotating element may include an outer ring rotatably coupled to an inner ring, wherein the outer ring is coupled to the housing. The foot may couple to the inner ring such that the foot rotates with respect to the housing. The foot may also be configured to contact an upper surface of a metal sheet and may be oriented such that while the metal sheet is being welded, the foot rotates about a central vertical axis and the laser welding pressure unit is able to move in any direction without the foot breaking contact with the surface.Type: GrantFiled: October 24, 2012Date of Patent: September 30, 2014Assignee: Benecor, Inc.Inventor: Jeffrey Don Johnson

Patent number: 8302842Abstract: A honeycomb core is created from a stack of metal sheets that are welded together using a serpentine weld path. Each sheet in the stack is welded to the sheet underneath. All the odd-numbered sheets, excluding the bottom sheet, are welded using a first serpentine welding pattern that includes a plurality of long welds and a plurality of short welds. All the even-numbered sheets are welded using a second serpentine welding pattern that includes a plurality of long welds and a plurality of short welds, such that the long welds of the second serpentine welding pattern are shifted from the long welds of the first serpentine welding pattern. When a sufficient number of sheets have been welded, the stack is trimmed to remove the short welds. The stack is expanded by pulling the sheets one from another to form the honeycomb core.Type: GrantFiled: September 16, 2009Date of Patent: November 6, 2012Assignee: Benecor, Inc.Inventor: Jeffrey D.
