Abstract: A method for qualifying a local loop for DSL service identifies the loop on an individual basis with respect to a plurality of other loops, while determining a qualification result based on descriptive data and a different data source as dictated by the state of the description data. The method includes determining an end to end path that individually identifies the loop, gathering descriptive data, and determining the qualification result. The qualification result is based on the descriptive data and further based on the different data sources dictated by the state of the set of loop description data.

Abstract: A ball check valve including a housing and a ball element movably positioned in the housing. An insert member is located at an inlet port of the housing, and an elastomeric element is molded directly onto the insert member and is positioned facing toward an outlet port of the housing for engagement with the ball element. A ball seat is ground into the elastomeric element at a precise angle matching a tangential angle of contact with the ball element such that engagement of the ball element with the ball seat forms a seal preventing fluid flow from the outlet port through the inlet port.

Abstract: A desk storage system for efficiently organizing various office implements using modular components assembled in one of a plurality of configurations according to user preference. The desk storage system includes modular components attachable to one another by connectors mounted on the periphery of the modular components. The connectors enable lateral and, selectively, angular tilt adjustment of adjacent modular components. A strong, rigid shelf is also provided for supporting the modular components, while also allowing the lateral and angular tilt adjustment of the modular components. The system further includes stacked trays selectively adjustable relative to one another. The trays are stacked using stacking brackets readily engageable between paper trays, while providing a strong, rigid connection.

Abstract: A window construction having fixed and movable frames and an associated latch assembly. The latch assembly includes a latch housing, a latch member reciprocable within said housing and a cam lock. The cam lock is rotatably mounted within the housing and has a first position wherein the cam lock urges a latch member into a locked position and a second position wherein the latch member may be moved to an unlocked position. The cam lock is preferably composed of a resilient, resinous material and has a cantilevered portion which engages a portion of the latch member. A special tool or key of predetermined configuration may be required to rotate the cam member. Among other uses, the latch may be employed in connection with double hung windows which are adapted to be tilted inwardly for cleaning. In such use the windows may be subjected to sliding movement regardless of the latch position, but tilting movement may be accomplished only when the latch assembly is in a locked position.
