  • Patent number: 10913018
    Abstract: A filter element for use in a housing of a filter assembly having a cover and a seal therebetween. The housing includes inlet and outlet valves. The filter element comprises a first endcap and a second endcap including an inlet valve actuator. A cylindrical ring of filter media extends axially between the first and second endcaps and surrounds a center tube that defines an outlet having an outlet valve actuator. A sleeve positioned to receive and exert force in a first and second direction surrounds a bias member. Threading the cover to the housing compresses the bias member causing the inlet and outlet valve actuators to actuate the inlet and outlet valves. Removing the cover causes extension of the bias member and the inlet and outlet valve actuators to retreat from the inlet and outlet valves before the seal between the cover and the housing is broken.

  • Patent number: 10239096
    Abstract: This invention relates to an apparatus for processing a baseplate assembly and more specifically to a transfer mechanism and a parts washer for processing baseplate assemblies. The transfer mechanism has a pivot arm that is mounted to a transfer and/or lift mechanism. The pivot arm holds a carrier unit having an abutment plate and a finger. The finger having an extended state and a retracted state relative to the abutment plate. The finger engaging and securing the baseplate assemblies to the carrier unit during the transport of the baseplate assemblies from a welder or tapper to a parts washer. The transfer mechanism picks the baseplate assemblies from the welder or tapper in a horizontally extending alignment and deposits the baseplate assembly in the parts washer in a vertically extending alignment. The parts washer then washes the baseplate assemblies, while the baseplate assemblies remain in a vertically extending alignment.
