  • MULTI-PIECE CURRENT SHUNT WITH CONDUCTIVE CHANNEL FOR UNIFORM CURRENT FLOW
    Publication number: 20210080488
    Abstract: A shunt is composed of multiple pieces with at least some of the pieces being connected by a conductive channel that provides uniform flow of current. The conductive channel may be a recess, raised portion, stand-alone component, or other channel that directs current to flow from one piece of the shunt to another piece in a uniform manner, resulting in an accurate current reading for the shunt. Further, the shunt may include multiple pieces that are composed of different materials.

  • Incinerator transport trailer and system
    Patent number: 10894499
    Abstract: An incinerator transport trailer has a chassis and an incinerator receiving and supporting cradle pivotally attached to the chassis for movement relative to the chassis between a travel position in which the cradle is positioned parallel to and extends along the chassis and a raised position in which the cradle extends generally perpendicular to the chassis. A first incinerator engagement is attached to the cradle toward a first end of the cradle for back-and-forth movement along a direction extending generally between the first and second ends of the cradle. A second incinerator engagement is attached to the cradle toward a second end of the cradle. The first incinerator engagement is movable to increase or decrease a distance between the first incinerator engagement and the second incinerator engagement to removably secure an incinerator to the cradle.
