  • Patent number: 6755565
    Abstract: A mixing system for mixing material includes a mixer having a housing, an arm in operable cooperation with the housing, wherein the arm is constructed and arranged to rotate about a first axis of rotation, and a basket constructed and arranged to rotate about a second axis of rotation in the opposite direction while the arm is rotating. A holder is removably received within the basket. A material container receives the material to be mixed, and the container is received within a lower half of the holder.

  • Patent number: 6565239
    Abstract: A luminaire flush with a horizontal surface and comprising a housing, an optical window, a light source, and an optical element. The housing has an internal cavity disposed beneath the horizontal surface and defines an opening disposed adjacent the horizontal surface. The optical window, substantially flat and transparent, has a surface that overlays the housing opening. The light source, disposed within the housing cavity, provides a spatial light distribution pattern which defines an optical axis that is disposed substantially perpendicular relative to the optical window surface. The optical element, also disposed within the housing cavity, redistributes light rays emitted by the light source along preselected angles relative to the horizontal surface.

  • Patent number: 6543911
    Abstract: A highly efficient luminaire. The luminaire includes a light source that emits light. The emitted light is redirected by a light transformer having a curved circular reflective interior surface, the reflective interior surface reflecting the light in a predetermined pattern. A substantial amount of light being may be reflected close to an axis coincident with a radial line defining a radius of the circular reflective interior surface. Additionally, a substantial amount of light may be reflected in a pattern with low divergency or parallel with an axis of the light transformer. The light is transmitted to the exterior of the luminaire by an optical window.
