  • Patent number: 7066776
    Abstract: Vessel provided with a propeller protruding beyond the hull fitted in a propeller tunnel that extends as far as the stern of the vehicle. The surface area of the propeller tunnel recessed in the hull in a direction perpendicular to the longitudinal axis of the vessel is essentially constant over the length of the cavity. The width of the cavity increases in the upstream direction to the end of the tunnel.

  • Patent number: 6974299
    Abstract: Collection assembly for collecting and stacking articles. The articles are first moved adjacent to one another with the aid of positioning elements. The positioning elements comprise the conveyor belt that extends obliquely with respect to the distribution conveyor and that can be moved over the distribution conveyor to a greater or lesser extent. After bringing the articles into a row on a discharge plate, these are stacked, optionally via a buffer plate, on a lift plate and after the stack has been compressed to some extent this stack is slid into the box in such a way that the products concerned are placed vertically in the box.

  • Patent number: 5605031
    Abstract: A device for packing filled bags in outers comprises means (1, 3) for placing the bags in a row in such a way that they overlap each other, a suction box (8) with suction cups (13, 14) for retaining filled bags, which suction box can be moved between a pick-up position above the means for forming a row and a delivery positon above an outer or device for feeding in an outer, and means (4, 6) for pushing a formed row of bags up against the suction cups of the suction box. The suction box (8) has one or more rows of suction cups (13) having mouths placed relatively high up and one or more rows of suction cups having mouths placed relatively low down. In a tint pick-up position of the suction box, the suction cups having mouths placed high up are positioned directly above the means for forming a row of bags, and in a second pick-up position of the suction box, the suction cups having mouths placed relatively low down are situated directly above the means for forming a row of bags.

  • Patent number: 5022218
    Abstract: A device for filling outers with filled bags comprises a cassette (1) for the accommodation of a number of bags or rows of bags stacked on each other, feed apparatus (10, 11) for filling the cassette with bags from the top, and discharge apparatus (4, 5) for sliding the stack laterally out of the cassette into a tilted outer. For the purpose of simplification and for making the structure less susceptible to faults, the cassette has a fixed position, and a sliding cover plate or deposit plate (8) is placed at the top side of the cassette for supporting a row of bags. Structure (9) is present for sliding the cover plate (8) to and fro between a covering position in which the top side of the cassette is covered and a free position in which the bags can fall into the cassette.

  • Patent number: 4984677
    Abstract: A device for transferring objects, such as filled bags, from a conveyor to a collection device, such as a box, placed below the conveyor comprises two conveyor belts (1, 2) placed adjacent to each other. In the conveying position, the top parts of said conveyor belts together form one conveying face. Each of the conveyor belts (1, 2) is disposed on a tiltable frame (4). In order to make the drive of the conveyor belts (1, 2) extremely simple and to make it possible to adjust the conveyor belts at right angles to their direction of conveyance, the drive comprises a drive pulley (3) acting upon the top part of the belts (1, 2) in the conveying position thereof.

  • Patent number: 4781011
    Abstract: For packing filled bags into boxes an apparatus is provided which includes a receiving plate for collecting bags in a row, and a pusher plate for pushing the row to a position above a box to allow the row to fall into the box. To achieve an accurate positioning of the rows of bags in a box and a high degree of filling of the box a movable cassette is positioned above a waiting box. In order to bridge over the varying distance between the cassette and the receiving plate, a bridging plate extends between the cassette and the receiving plate. Preferably the bridging plate is in the form of a slide plate which is joined to the cassette.

  • Patent number: 4697452
    Abstract: For testing filled closed packages of flexible material for leaktightness use is made of an apparatus provided with conveyor means (2) for feeding packages in line and with means for applying pressure to the packages. The last-mentioned means consist of two pressure belts (4, 5) disposed a short distance apart. In the gap (6) between the pressure belts (4, 5) is situated a pivoting arm (8) or a shoe (20) having a pressure chamber (21), whereby it can be determined whether the portion of the package lying in the gap between the pressure belts is taut. This apparatus is in particular suitable for testing bags having two curved surfaces which are joined together by three or four sealing seams.

  • Patent number: 4398383
    Abstract: An apparatus for packaging product-filled sealed bags in cases includes an inclined plate and an extensible pushing plate operable to arrange a predetermined number of bags fed from an infeed conveyor in a row on the inclined plate. The row is supported thereon by a movable support pivotable from a holding or supporting position to a retracted position in which the row is free to slide downwardly off the inclined plate and onto a retractable bottom plate. The movable support further operates to position each row formed in an upright position on the bottom plate, where a predetermined number of rows are successively accumulated. The accumulated rows are laterally supported on one side by the movable support and on the other side by a cylinder having a supporting back plate at the end. When a predetermined number of rows have been accumulated, the bottom plate is retracted to allow a cylinder-operated pushing plate to push the rows downwardly into an underlying open case.
