Patent number: 11846609Abstract: An electric actuator includes a stationary support and a guide system having a single stationary guide joined to the stationary support having an axis. The actuator also includes a stationary assembly secured to the stationary support. A moving assembly is movable relative to the stationary support on the guide, where the moving assembly and the stationary assembly provide at least two sets of interacting magnetic fields disposed about the guide at equal angular intervals. A test specimen support is joined to the moving assembly and disposed on one side of the stationary support so as to move along the axis with movement of the moving assembly, the axis extending through the test specimen support.Type: GrantFiled: October 13, 2020Date of Patent: December 19, 2023Assignee: MTS Systems CorporationInventors: Dmitrii Pokhil, Byron Saari, Charles Groepper, Paul Carroll

Patent number: 10173044Abstract: This document provides fluid handling components. For example, this document relates to taper interface connections such as, but not limited to, luer taper interface connections used to couple fluid handling components in a medical or laboratory setting. In some embodiments, the threaded connection on the male portion of the taper interface is comprised of one or two opposing tabs, rather than a 360° collar like conventional luer lock fittings. As such, the taper interface components provided herein are readily manufacturable with a lower cost than conventional fittings that have a collar. In some embodiments, the taper interface components provided herein are configured for coupling by way of a quick connection technique.Type: GrantFiled: September 17, 2015Date of Patent: January 8, 2019Assignee: TA INSTRUMENTS—WATERS L.L.C.Inventors: Charles Groepper, Aaron M. Owens, Thomas M. Hays
