摘要： An apparatus and method for removing polymer solids from a slurry loop reactor. A discharge conduit having a longitudinal axis and an end section for removing polymer solids from the slurry loop reactor is provided. The discharge conduit is attached to the slurry loop reactor so that the longitudinal axis and at least a portion of an outer wall of the slurry loop reactor form an angle of less than about 90 degrees. The end section includes a first edge and a second edge that extends past at least a portion of an inner wall of the slurry loop reactor into a liquid reactor slurry. Polymer solids contained within the liquid reactor slurry are concentrated on the second edge so that an average polymer solids concentration in the discharge slurry is greater than an average polymer solids concentration of the liquid reactor slurry within the slurry loop reactor.

摘要： A method of reducing stray light contribution of a display system is described. Light rays are directed to at least one pixel of the display system and the light rays are modulated to form modulated light. In addition, the modulated light is directed to display optics, and the reflected light is directed away from the display optics.

摘要： A light source arrangement has a first light source, a second light source and a dichroic mirror. The dichroic mirror is disposed with the first and second light sources and configured to reflect a predetermined portion of the light emitted from the first light source and to transmit the remaining portion. The dichroic mirror is also configured to reflect light emitted from the second light source so that it propagates in the same direction as the remaining portion of the light from the first light source which is transmitted through the dichroic mirror.
