  • Publication number: 20150198549
    Abstract: A foam sensor system includes a flexible bag comprised of a polymeric material and bounding a compartment. A foam sensor assembly is mounted on the flexible bag and includes a foam contact disposed within the compartment of the flexible bag. A ground assembly is mounted on the flexible bag and includes a ground contact disposed within the compartment of the flexible bag, the foam sensor assembly and the ground assembly being configured so that an electrical potential can be applied between the foam contact and the ground contact.

  • Publication number: 20150117142
    Abstract: A fluid mixing system includes a container, such as a flexible bag, bounding a compartment. A flexible drive line is disposed within the compartment, the drive line having a first end rotatably connected to a first end of the container and an opposing second end rotatably connected to a second end of the container. At least one mixing element, such as an impeller, is coupled with the flexible drive line. Rotation of the drive line facilitates rotation of the impeller within the container.

  • Patent number: 8919210
    Abstract: A load cell lockout system includes a lower support, an upper support, and a load cell disposed between the lower support and the upper support. The upper support is movable relative to the lower support between a first position wherein a first load is applied by the upper support to the load cell and a second position wherein either a second load that is lighter than the first load is applied by the upper support to the load cell or no load is applied by the upper support to the load cell. A lockout includes a cam with an eccentric perimeter side edge, the cam being rotatable between a first orientation whereby the upper support is placed in the first position and a second orientation whereby the upper support is placed in the second position.

  • Publication number: 20140076454
    Abstract: A fluid manifold system includes a manifold port assembly having a housing with an inlet port and a plurality of outlet ports formed thereon and a carousel having a plurality of spaced apart fluid paths that extend therethrough from a first end to an opposing second end. The carousel is rotatably coupled with the housing so that when the first end of each fluid path is aligned with the inlet port on the housing, the second end of each fluid path is aligned with a corresponding different one of the plurality of outlet ports. A container is fluid coupled to each outlet port by a fluid line. The inlet port can be selectively coupled with a fluid source while a motor can control rotation of the carousel relative to the housing.
