  • Patent number: 9682488
    Abstract: A trimmer comprises two counter-rotating barrels side-by-side above one cutting reel. When viewed from the front, the left barrel rotates counter-clockwise while the right barrel rotates clockwise. Plant material in the barrels accumulates on the uphill side of each barrel, relative to its rotational direction, as the plant material traverses the rotating barrels. This configuration positions the uphill sides of both barrels proximate to the one reel. The barrel perforations are rifled to assist in moving the plant material through the barrels. Screw jacks are employed to tilt the trimmer; hardware facilitates use of two such trimmers in series.

  • Patent number: 9214336
    Abstract: The surface of a sapphire substrate having a c-plane main surface is patterned by ICP dry etching. The patterned sapphire substrate is thermally treated in a hydrogen or nitrogen atmosphere at a temperature of less than 700° C. or at a temperature of more than 800° C. to 1100° C. An AlN buffer layer is formed by magnetron sputtering on the surface on the patterned side of the sapphire substrate heated at a temperature of 200° C. to less than 700° C. On the buffer layer, a Group III nitride semiconductor layer having a c-plane main surface is formed so as to have a thickness of 1 ?m to 10 ?m by MOCVD.

  • Publication number: 20090188999
    Abstract: A device and method to provide a simplified wash process and controlled disintegration of a soft substance, such as a gel, are disclosed. In use, a block of, e.g., gel matrix is placed in the device and washed with a series of appropriate solutions to remove interfering contaminants. The washing liquid is removed through a deformable narrow opening in the bottom of the device, and, subsequently, the gel block is extruded through the deformable narrow opening, by a physical force, such as centrifugal force, a vacuum or positive pressure from a gas or liquid, etc., resulting in fragmentation of the gel block into a series of particles of similar size. The fragmentation of the gel results from shear forces exerted onto the gel block traveling through the deformable narrow opening in the device.
