Patent number: 10914304Abstract: A pneumatic timing valve includes a spool and seal system having a first seal cartridge and a spool. The first seal cartridge has an annular body with radial ports. The spool is positioned within the first seal cartridge and movable between a first and second position. The spool has a central bore and radial ports that intersect the central bore. The radial ports of the spool complement the radial ports of the seal cartridge. The seal cartridge radial ports, the spool radial ports, and the central bore of the spool define fluid flow passages.Type: GrantFiled: April 28, 2016Date of Patent: February 9, 2021Assignee: Graco Minnesota Inc.Inventors: Jacob K. Krech, Corey D. Meyer, David J. Allie, Daniel J. Rogers, Derek R. Shaw, John R. Ingebrand, Joseph A. Daniski

Patent number: 8299373Abstract: The outer case of the display module 10 is constructed of static dissipative polypropylene components that house a circuit board 16 and display 14. When the display module 10 utilizes the hand held pendant option a front cover 18 is used. This front cover 18 provides a viewing window 20 to the display 14 and a flat surface to attach the membrane 22. When the display module 10 is to be mounted inside of an enclosure, the front cover is replaced by a flat plate 28 that then provides the viewing window 30 and flat surface membrane 32 requirements. The rear portion 12 of the display module 10 is used with either option and contains the necessary features to allow for either the front cover 18 or the flat plate 28 to be attached.Type: GrantFiled: June 12, 2008Date of Patent: October 30, 2012Inventors: Derek R. Shaw, John C. Holman, Christopher M. Lange, Nicholas D. Long, Greg T. Mrozek, Michael L. Kashmark
