Abstract:
A system for separating pieces of plastic bag from ground yard debris and the like, e.g., asphalt shingles. A conveyor conveys the debris material along a conveyor path and an agitator bounces the conveyor to cause the lighter plastic to reposition to the top of the material on the conveyor. A suction tube end is positioned over the debris material following agitation to draw the plastic off the top of the material. The tube end is selectively adjustable to enable discriminate suction effect to draw off a maximum amount of plastic and a minimal amount of nonplastic recyclable debris.
Abstract:
A method for characterizing the performance of an electrostatic chuck prior to installing the chuck in the vacuum chamber of a semiconductor processing system in a production line. One or more characteristics of the electrostatic chuck are measured and compared with the known characteristics of a reference chuck. The comparison indicates the performance of the chuck and projects the performance of the chuck in an actual operating environment. The characteristics that are measured include the chuck impedance, the current-voltage characteristic of the chuck, the local plasma density proximate the support surface of the chuck, and the cooling or heating rate of the chuck.

Abstract:
A beam coupler alignment system for a fiber laser system is disclosed. The system includes a focus adjust collimator assembly having an inner and outer housing assembly portion. The inner assembly includes a coupler housing assembly and a modified lens housing received within and adjustable relative to via a mechanism configured and arranged to apply an asymmetric binding force in a predictable and repeatable manner. A lever assembly contacts the lens housing and exerts an off-center (asymmetric) force relative to coupler housing assembly creating a friction bind eliminating X and Y axis movement yet allowing Z axis movement with minimal effort. The assembly may further include an alignment mechanism configured and arranged to optically align an input collimator unit and an output collimator unit of a complex fiber laser system about a common optical axis using the proposed assembly.

Abstract:
A shock absorber for an end of a steel or cast-iron container for the transport of spent-fuel elements is in the form of a casing with a recess receiving the end of the container and having, in turn, a stepped-pyramid element which decreases in wall thickness from the region surrounding the container end of a free end of the stepped pyramid.
