摘要： The disclosed method and apparatus measures radial deviations along the axial length of a work roll with a number of axially spaced displacement detectors and at least three axially spaced motion detectors mounted ona detector mount that moves axially along the roll. A calculator responds to the motion detectors to determine errors in the motion of the mount to correct the output of the detectors and sums the deviators to generate overall deviations.

摘要： A multiplexed communication system for automatically setting up a multiplexed call circuit between exchanges upon occurrence of a call only when the multiplexed call circuit is required while otherwise releasing the multiplexed call circuit. The multiplexed communication system includes a plurality of exchanges, each of which includes multiplexing/demultiplexing apparatus for compressing and multiplexing data inputted from first input/output to thereby output the compressed and multiplexed data to second input/output ports and for demultiplexing and expanding data inputted from the second input/output to thereby output the demultiplexed and expanded data to the first input/output port, control information messaging apparatus for messaging control information, first detection apparatus for detecting occurrence of a compressible call, and second detection apparatus for detecting that all the calls connected to the first input/output ports have been released. Upon detection of the compressible call by the first detection apparatus, a circuit is set up between the exchanges through the multiplexing/demultiplexing apparatus while the control information is transferred between the exchanges through the call control information messaging means, to thereby connect the call to the first input/output ports between the exchanges. When it is detected that all the calls connected to the first input/output ports have been released, the circuit between the exchanges is released.
