  • Patent number: 4197651
    Abstract: A process for continuously testing the thickness of the enamel coating of electric wires, in which the wire, after enamelling, passes between a fixed and a movable measuring roller. The wire is wrapped around the fixed measuring roller such that its wrap-around angle has a value between 0 and 15 degrees and the fixed and movable measuring rollers are positioned relative to each other such that their respective planes of symmetry are vertically displaced by a value between 0.5 and 2 mm. Using the process according to the invention, the thickness of enamel applied to the wire can be kept constant to about 0.5 .mu.m.

  • Patent number: 4198666
    Abstract: A positioning device for a write/read magnetic head in a magnetic disc data storage device comprising a motor-driven guide disc, with a spiral-shaped guide wall arranged at right angles to the plane of the guide disc, for a guide element in the form of a ball-bearing on a magnetic-head support. Due to the greatly reduced friction it is possible to achieve highly accurate positioning within an extremely brief period of time and with an extremely low power requirement. This device may be used to position the heads in magnetic disc systems for the recording and/or reproduction of analog or digital signals.
