  • Patent number: 7229045
    Abstract: A store control device of an intermediate store carries, on a pivot mounting which is mounted on a chassis capable of travelling along a track, so as to be rotatable about a vertical axis through 360°, a pick-up device for a paper reel which has a continuous track section for holding a carriage loaded with a paper reel and raisable and lowerable claws arranged on both sides thereof. Storage tracks which are in the form of short stub tracks and have carriages and which form storage places for holding paper reels with axes oriented transversely to the track are arranged on both sides of the track. Before storage of a paper reel in the intermediate store, the pivot mounting is rotated so that the winding direction of the stored paper reel corresponds to a required value. The claws can also be formed so as to be longitudinally displaceable on both sides by at least a reel length, in which case only a support surface is provided between them and the storage places are equipped with stationary storage troughs.

  • Publication number: 20060049296
    Abstract: A store control device (6) of an intermediate store carries, on a pivot mounting (19) which is mounted on a chassis (18) capable of travelling along a track (5), so as to be rotatable about a vertical axis through 360°, a pick-up device for a paper reel (4) which has a continuous track section (22) for holding a carriage (8) loaded with a paper reel (4) and raisable and lowerable claws (23b) arranged on both sides thereof. Storage tracks (12) which are in the form of short stub tracks and have carriages and which form storage places (3) for holding paper reels (4) with axes oriented transversely to the track (5) are arranged on both sides of the track (5). Before storage of a paper reel (4) in the intermediate store, the pivot mounting (19) is rotated so that the winding direction of the stored paper reel (4) corresponds to a required value.

  • Patent number: 5830588
    Abstract: The invention relates to a method of producing a magnetic material for use in an ultrahigh density magnetic recording medium and to the medium itself. The method general includes the steps of vaporing a ferromagnetic lanthanide rare earth, growing clusters of the ferromagnetic lanthanide rare earth at a temperature below the temperature at which the ferromagnetic lanthanide rare earth forms locked-moment clusters, filtering superparamagnetic clusters from locked-moment clusters, and collecting the locked-moment clusters. Preferably, the ferromagnetic lanthanide rare earth is a ytterbium rare earth. Advantageously lanthanide alloys, mixtures of lanthanide rare earths and alloys of a mixture of lanthanide rare earths can be used. The filtering employs a gradient magnetic field to separate superparamagnetic clusters from moment-locked clusters. The gradient field magnet separates the superparamagnetic clusters which deflect by a large amount from the locked-moment clusters which deflect by a small amount.
