  • Patent number: 8176652
    Abstract: An apparatus and method for a water removing roller device for removing excess water from the hide of a cattle, which uses pliable urethane roller stacks that can be attached by an arm structure. The roller structure can be mounted on a hinge to an arm thereby allowing the structure to swivel. The arm can be attached to a stationery device with a hinge, which is also allowed to swivel. A tension device, for example, a spring or a hydraulic cylinder can be attached to the back of the arm and connected to the stationery device to provide enough tension on the structure to keep the rollers in contact with the cattle hide, thereby pressing out the water allowing it to run off prior the blood plasma saving section.

  • Publication number: 20080256823
    Abstract: A process for changing the properties of the wood in timber by applying varying pressure progressively along the length of the timber. The timber is caused to contract to facilitate the removal of wood water along the grain of the timber, to bend or straighten the timber, to assist the timber in contracting to its strunk state or to a state of increased density and to facilitate gluing of the processed timber. To facilitate the process timber can be heated by micro or radio waves, by direct heat or an electrical current can be applied to the timber. The heating means is generally also applied progressively along the length of the limber. The planes of pressure contact as applied to timber surfaces are not parallel to each other.

  • Patent number: 6004468
    Abstract: An apparatus for processing a solid-liquid material comprises a housing formed with a series of interconnected chambers defined by chamber walls with at least two drums mounted in series within the chambers. Each chamber receives one of the at least two drums for rotatable movement therein. Each chamber and the associated drum are dimensioned to define a region therebetween to retain the solid-liquid material. The regions of adjacent chambers communicate with each other to define a continuous passage from drum to drum through the apparatus. An inlet in the housing admits the solid-liquid material to the passage, and an outlet permits extraction of a processed solid-liquid material from the passage. Each drum rotates in a direction opposite to the adjacent drum to advance the solid-liquid material through the passage from drum to adjacent drum in a sinuous path such that the curvature of the solid-liquid material changes when passing from drum to adjacent drum.
