Abstract: The block based data storage subsystem combines the functions of data storage/retrieval with block based data management functions, including but not limited to: Hierarchical Storage Management (HSM), Live Data Backup, Fault Tolerance, Capacity Planning, Performance Optimization and Dynamic Load Balancing. This system solves many storage management problems with a single technology and is completely independent from, and non intrusive to, the system it attaches to and has resources specifically designed to perform data management functions. The perspective of block data management is a much finer granularity and much simpler than existing data file based technologies.

Abstract: A wire stripper having a two-part hollow body and a group of circular cutters mounted within that body. The two body parts are interconnected for relative movement between an open position and a closed position at which the cutters are engageable with and penetrate into a cable end portion positioned within the body. Locating structure functions to properly position that cable end portion within the body. The cutters are spring biased so as to be movable into and out of a position at which they have maximum penetration in the cable end portion. A cable end stop fixes the axial position of the cable end portion and is movable into an inoperative position in response to the body parts being moved into the closed position. A handle is rotatably connected to the body and includes a releasable retainer which is engageable with the cable to hold the cable against movement relative to the handle.

Abstract: A torque wrench having a reaction bar and an arm extending laterally in the same direction from a work engaging head. The arm is flexed in response to torque applied to the head through the bar and cooperable members on the bar and arm respectively engage as a consequence of that flexing. The member on the bar is a pivoted lever which responds to the aforementioned engagement to swing towards a signal generating position at which it causes a switch to operate to close a circuit contained within a handle part of the bar. The circuit includes audible and visible signal means and those means are energized while the circuit remains closed. The switch is normally urged towards a circuit closed position but is prevented from reaching that position by a blocking member, and the aforementioned pivoted lever renders that blocking member inoperative when the pivoted lever is swung into its signal generating position.
