Abstract: A strip of easily magnetizable material of low remanence, having magnetic properties equal to or better than those of the core of the magnetic heads on a revolving headwheel of a video tape machine is provided as a magnetic shunt for each head, disposed in the neighborhood of the core gap, but spaced therefrom at a distance much greater than the gap width, for reducing the spread of stray flux when the head is used for recording and intercepting stray flux from other heads when the head is in the playback mode. Among the many ways in which the shunt can be provided are individual bridge strip mounted on the headwheel to bridge over each head laterally, a horseshoe-shaped strip covering the annular gap in which the headwheel revolves for the portions of that gap over which the tape passes, but spaced away from the tape, and strips mounted on the stationary guide drums or embedded in the headwheel periphery.

Abstract: A device for sealed attachment of substantially flat-surfaced cover strips, especially of sheet metal, for single- or double-curve roof surfaces of buildings, with top and bottom clamping members, which can be braced for the side attachment of adjacent cover strips by opposing bolts and which can be attached to a supporting frame. The clamping members have flat clamping surfaces to contact the substantially flat-surfaced cover strips and have clamping bolts that extend through openings on the lengthwise edge of at least one of any two adjacent cover strips. Cover rails are attached to the top clamping members and pass therethrough and are clamped by means of crosspieces which feather out to the side, which on their lengthwise edge carry sealing strips pressed against the outsides of adjacent cover strips.

Abstract: A traveling undercarriage for a mobile container or the like, comprising a substantially rectangular-shaped frame having two parallel main supports extending transversely with respect to the direction of displacement of the undercarriage and connected at their ends with one another. Rollers are attached at transverse supports connected with the main supports. The transverse supports carrying the rollers or rolls are detachably secured by connection elements with the main supports. Attachment elements are provided which are suspendible at the main supports and at which there are secured transverse walls of the container.
