  • Doctor blade holder and adjustment mechanism
    Patent number: 10661555
    Abstract: A doctor blade holder and adjustment mechanism that may be utilized with a flexographic printing system. The doctor blade holder and adjustment mechanism may utilize a constant displacement of the doctor blade against an anilox roller, rather than a constant force, to reduce ink build up on the back side of the doctor blade, and subsequently, intermittent dropping of the accumulated ink onto the post-shearing side of the anilox roller (“spitting”). The doctor blade holder and adjustment mechanism may provide adjustability of a combination of doctor blade pressure, angle and displacement.

  • Adjustable stride elliptical motion exercise machine with large stride variability and fast adjustment
    Patent number: 9636540
    Abstract: Elliptical exercise machines with a footskate on a reciprocating rail that provides for the ability to alter the horizontal stride of the user utilizing the machine, without significantly altering their vertical stride height on the machine. This is generally performed by altering the angle through which any point on the rail can, and does, move. Such adjustment may be performed by having the rail attached to a swing arm, where the arc of rotation of the swing arm relative to the frame is altered.
