Abstract: For use with a communication station having a database containing past communication event information pertaining to the station, systems for, and methods of, predicting a future communication event pertaining to the station. In one embodiment, the system includes: (1) correlating logic that analyzes the past communication event information to determine whether a correlation exists in the past communication event information and (2) predicting logic, coupled to the correlating logic, that examines a current communication event pertaining to the station and predicts the future communication event based on the current communication event and the correlation.

Abstract: Polychlorinated biphenyls are removed from oil by extracting the biphenyls into methanol. The mixture of methanol and extracted biphenyls is distilled to separate methanol therefrom, and the methanol is recycled for further use in extraction of biphenyls from oil.

Abstract: This invention is an efficient hand tool for precisely slitting the sheath of insulation on an electrical cable--e.g., a cable two inches in diameter--in a manner facilitating subsequent peeling or stripping of the insulation. The tool includes a rigid frame which is slidably fitted on an end section of the cable. The frame carries a rigidly affixed handle and an opposed, elongated blade-and-handle assembly. The blade-and-handle assembly is pivotally supported by a bracket which is slidably mounted on the frame for movement toward and away from the cable, thus providing an adjustment for the depth of cut. The blade-and-handle assembly is mountable to the bracket in two pivotable positions. With the assembly mounted in the first position, the tool is turned about the cable to slit the insulation circumferentially. With the assembly mounted in the second position, the tool is drawn along the cable to slit the insulation axially.
