  • Publication number: 20110311172
    Abstract: The invention relates to a component (1) with an axis (A) consisting of at least a first layer (2) in the form of a tubular body and at least a second layer (3) which is arranged outside and/or inside of the tubular body (2) and which is firmly connected with the first layer (2). To make the element lightly and abrasive resistant simultaneously, the first layer (2) consists of a composite material, wherein the second layer (3) consists of a hard material. Furthermore, the invention relates to a method for the production of such an element.

  • Patent number: 5071264
    Abstract: A radial or axial bearing has plastic casing rings formed as strips whose ends form junctions offset from those of the spring rings and/or race rings received in grooves and beds of the casing rings on which the bearings ride.

  • Patent number: 4103313
    Abstract: A terminable scanning movement of a video tape track with respect to the scanning path of a playback head in a helical scan video recorder is provided with a staircase-type tracking control voltage. During each scanning cycle, in which each increment of the scanning voltage provides a monotonic, unidirectional translation of the tape track with respect to the scanning path by suitably altering the velocity of advance of the tape, the occurrence of a successive minimum and maximum in the resulting variation of detected video amplitude results in the generation of a stop signal. Such signal, which ideally coincides with the maximum amplitude of the detected voltage and thereby the desired registration position between the video tape track and the scanning path, is employed to stop the progression of the staircase voltage and to thereafter store the then-attained value for the maintenance of the tape drive servo at the optimum position.

  • Patent number: 3943565
    Abstract: An arrangement for initiating and terminating a scanning movement of a video tape track with respect to the scanning path of a playback head is described for use in a helical scan video recorder. A disturbance detector is actuated when the detected video pulse envelope exceeds a predetermined amplitude indicative of a minimum displacement of the track from the scanning path. Such actuated detector operates to couple the servo unit of the tape velocity regulator to a tracking controller. The controller initiates a track scanning operation by applying to the tape drive servo a cyclic modulation which is superimposed upon an error signal derived from the detected video envelope.
