A control system for a plurality of I/O apparatuses used for transferring data between a main memory and an I/O apparatus controlling device through a channel control device. If an error occurs in the data transfer, no response signal is sent to the I/O apparatus controlling device from the channel control device and the absence of the response signal is detected by time supervision in the supervi...

The coil winding (1) consists of a braided wire which consists of a relatively large number of conductor strands which are interleaved with one another in the form of a flexible tube in such a manner that the individual conductor strands change their position on the circumference of the flexible tube to such an extent that they in each case assume every possible position with respect to the flexib...

The sonde comprises a measuring wheel carried by an arm which holds it in contact with the borehole wall and rotates it around the sonde axis so that the measuring wheel follows a helical path on the borehole wall as the sonde is raised in the borehole.
