  • Patent number: 8591096
    Abstract: A variable height blender system is disclosed that includes an industrial blender carried by a first lift and a second lift for moving the blender up and down into any of various vertical positions. The variable height blender system includes drive controls for independently controlling movement of the first and second lifts, and a synchronizer in communication with at least one of the first and second drive controls for synchronizing the movement of the first and second lifts to maintain the batch blender substantially level. The synchronizer includes a level sensor that senses a tilt of the batch blender with respect to a local gravity vector and sends level reading signals to the synchronizer for use in independently adjusting the speeds of the first and/or second lift.

  • Publication number: 20120260712
    Abstract: A device and method for twisting a work piece about an axis. The device includes first and second linear actuators attached to opposite sides of a shaft. The device also includes a first clamp attached to the shaft and a second clamp aligned with the first clamp along the axis. The first clamp is disposed between the linear actuators and the second clamp. Movement of the first and second linear actuators causes the shaft and first clamp to rotate about the axis while the second clamp remains in a fixed position. The method includes the steps of retaining a work piece within the first and second clamps, activating the first and second linear actuators in opposite directions causing the first clamp to rotate about the axis, and maintaining simultaneously the second clamp in a first position, whereby the work piece is twisted along the axis.

  • Patent number: 8226022
    Abstract: A mixer for mixing and/or blending product, such as granular material, includes a chopper disposed above an agitator assembly. The chopper preferably includes two sets of intersecting chopper blades that rotate in opposing synchronized motion in a zone of fluidized flow of product caused by the agitator assembly. A shroud above the chopper can be used to redirect product sprayed upwardly from the chopper blades back laterally into the zone of fluidized flow of product.
