Patent number: 9482360Abstract: A solenoid valve assembly includes an armature having a longitudinal axis and an ovular cross-section, the armature being moveable along the longitudinal axis from a first position to a second position, and a bobbin including a solenoid coil configured to electromagnetically move the armature when energized. The bobbin defines a recess also having an ovular cross section for receiving the armature and restricting lateral movement of the armature, thereby providing a linear actuation path for the armature along the longitudinal axis. A flux coupler and a flux bracket form a magnetic circuit with the bobbin to electromagnetically move the armature. The flux bracket has a pole piece with a commensurate ovular cross-section that limits the movement of the armature along the longitudinal axis, thereby determining a stroke length of the armature. During manufacture, the flux bracket, and therefore the pole piece, are moved relative to the flux coupler to set the stroke length.Type: GrantFiled: July 14, 2014Date of Patent: November 1, 2016Assignee: Parker-Hannifin CorporationInventors: Daniel L Bantz, Nick J Difazzio, Matthew R Kearsley, Leonard E Prais, Scott J Snyder, Thomas Theilmeier, Yong Wang, Donald S.

Patent number: 9470215Abstract: Provided is a liquid handling device for use in a liquid handling system including a plurality of the liquid handling devices assembled in side-by-side relationship at a center-to-center spacing of X. The device includes a barrel, plunger, motive device and electronics assembled together in an envelope having a front portion including at least the barrel and plunger, and a rear portion including at least a portion of the electronics. The rear portion has a thickness greater than X but no greater than 2X, and the front portion has a thickness no greater than X and is laterally offset relative to a center plane of the envelope, whereby the liquid handling device can be assembled with another reversely oriented liquid handling device at a center-to-center spacing of X and a total combined width no greater than 2X.Type: GrantFiled: June 6, 2011Date of Patent: October 18, 2016Assignee: Parker-Hannifin CorporationInventors: Daniel L. Bantz, Paul M. Grippo, Donald S. McNeil, Kenneth D. Wynn, Angela Tseng

Patent number: 8158083Abstract: A system for dispensing microdrops of reagent in small, precisely metered quantities maintains the fluid reagent to be dispensed in a reservoir under a controlled pressure. The reagent is dispensed through multiple nozzles connected to solenoid-actuated valves that control the flow of the reagent from the reservoir to the nozzles. Each valve is connected to one of the nozzles and electrical pulses are supplied separately to each of the valves to separately control the opening and closing of each valve to dispense predetermined quantities of the reagent through each nozzle at predetermined times.Type: GrantFiled: July 8, 2008Date of Patent: April 17, 2012Assignee: PerkinElmer Health Sciences, Inc.Inventors: Robert E. Krug, William Austhof, Dennis Makowski, Daniel L. Bantz, Marek Turewica

Publication number: 20080314412Abstract: A self-cleaning injection port assembly that uses a movable wash chamber closure device (26) for opening and closing an injection needle entry passage (34) of an injection port wash chamber. For sample injection, the wash chamber closure device (26) can be moved clear of the path along which the injection needle passes through the wash chamber into the injection port, thereby enabling insertion of the injection needle into the injection port. For washing, the wash chamber closure device (26) is moved to a position closing the entry passage (34) of the injection port wash, after which cleaning fluid may be circulated through the injection port for cleaning.Type: ApplicationFiled: December 4, 2006Publication date: December 25, 2008Inventors: Paul M. Grippo, Daniel L. Bantz, Frank Sylva, Thomas R. Londo
