  • Patent number: 11370609
    Abstract: A store for storing parcels has a main aisle and storage aisles arranged transversely to the main aisle and provided with storage places for the parcels. Beams arranged parallel to the main aisle and fastened to supports bear at least some of the weight forces acting in the storage aisles. A transport unit for transporting parcels is arranged in the main aisle. The transport unit has a first transport mechanism moving along the main aisle and a second transport mechanism that transfers parcels from the transport unit into a storage aisle, takes up parcels from a storage aisle and delivers them to the transport unit. The second transport mechanism has a slide movable transversely to the main aisle. The slide forms a rest for parcels during transfer and take-up. A tiltable platform that supports the slide is provided with a tilt mechanism that tilts the platform relative to the transport unit.

  • Patent number: 11286112
    Abstract: A warehouse has a rack with an aisle and rails fastened to the rack extend along the aisle. The rails are made of rail segments that have a first profile section with a top side running surface. A distribution vehicle is movable along the aisle on the top side running surfaces and transports goods to be stored or retrieved from the rack. A pressure distribution bar is arranged where a first rail segment abuts a second rail segment. The pressure distribution bar has first and second length portions. The first length portion is supported against the first profile section of the first rail segment, the second length portion is supported against the first profile section of the second rail segment. A pressure transmission element has a first end supported from below against the pressure distribution bar and a second end supported against a counter bearing arranged at the rack.

  • Patent number: 4091429
    Abstract: The invention relates to a device for magnetic recording which is provided with a layer of a magnetizable material which is provided on a support and has an easy axis of magnetization which is at least substantially perpendicular to the plane of the layer, which layer is suitable to support magnetic domains having a direction of magnetization which is opposite to the direction of magnetization of the remainder of the layer, the device also comprising a device for producing a magnetization field having a field direction perpendicular to the plane of the layer, said layer being destined to cooperate with a recording medium which is relatively movable with respect to the layer.

  • Patent number: 3944842
    Abstract: A magnetic device comprising a first and a second plate of a magnetic material between which domains are situated. An interaction force occurs between the domains in the two plates. Stable domain positions in a second plate define equally stable domain positions in a first plate. One or both plates can be provided with domain guiding structures. Domain displacement in one plate can control a domain displacement in the other so that a variation in the interaction force is produced.

  • Patent number: 3938111
    Abstract: Magnetic device comprising at least one thin layer of a magnetisable material which has a preferred direction of magnetisation substantially at right angles to the surface of the layer. Magnetic domains are produced by a magnetic field which is situated substantially in the plane of the layer and does not change direction and enables similar domains to be produced. The domains are there after maintained by a field normal to the layer. A domain guide structure may also be provided on the layer to move the domains.
