Abstract: The present invention relates to spring conductors used within modular jack assemblies. The spring conductors electrically connect with conductors residing on a multi-connector plug to connect communication equipment, digital or audio, to a transmission line. The spring conductors maintain connection with the conductors on the plug by a spring force inherent in the spring conductor. The present invention measures this spring force with a probe inserted into the modular jack assembly. The output of the probe being proportional to the spring force.

Abstract: A Torque Tool Calibrating Machine comprising an elongate torque tool engaging transducer including a strain gauge and mounted on a turning axis; an electronic analyzer connected with the gauge and operating to analyze, translate and display the voltage drop across it in torque force units and to emit a control voltage when it operates to display a predetermined maximum units of force, a manually driven gear transmission to turn the transducer including drive and driven gear wheels, a turntable supported on said turning axis and coupled with the transducer, an elongate lever arm projecting radially from the turntable and drivingly coupled with the transmission to selectively rotate the arm, table and transducer clockwise and counterclockwise, and a locking mechanism selectively operable to lock one of the gears against clockwise or counterclockwise rotation and including solenoid-acutated latch units with pawls that engage the gear when the solenoids are energized; a controller circuit connected between the an
