Clutch Take-up Patents (Class 40/498)
  • Patent number: 8904683
    Abstract: A device for successively changing elongated flexible objects from an active viewable position to a non-active, non-viewable position includes a rotatable drum to which the flexible objects are attached, a motor driving the rotatable drum in opposing rotational directions, and a controller unit controlling motor speed and direction. A balancing spring is preloaded when the flexible objects are unwound from the drum, providing a lifting force when the flexible objects are wound up on the drum. By using a freewheeling clutch, preloading only occurs in one rotational direction, the balancing spring freewheeling in the other direction, taking no load. Utilizing a magnetically interactive identification strip the device gains highly accurate information on the position of the flexible elongated objects. By pre-attaching the flexible elongated objects on each other and providing the identification strip on the designated carrier flexible object exchanging the set of flexible elongated objects is made very simple.

  • Patent number: 6381888
    Abstract: A device for successively changing elongated flexible sheets or similar flexible objects from an active position to non-active positions includes a drum, relative to which the sheets or similar flexible objects are fixed. The drum is rotatable in two opposing rotational directions. The rotational directions of the drum are controlled by a timing device in relation to the rotational speed of the motor so that rotation takes place in a first direction for such a time that the sheet located in the active position becomes wound up onto the drum and that a second sheet, located in the first rotational direction after the first sheet, is carried to a position from which the second sheet is unwound from the drum to the active position, upon rotation of the drum in the other rotational direction. Thereafter the drum is rotated in the other rotational direction for such a time that the second sheet becomes unwound from the drum.

  • Patent number: 6190489
    Abstract: A lamination method, which is a method in which a dry resist film, formed by providing a color resist layer on a base film, is cut based upon the length of a substrate in the feeding direction, and press-bonded onto the substrate, and then the color resist layer is transferred onto the substrate by separating the base film, is provided with the following steps: in the cutting process, cutting the film so that the rear end of the dry resist film, after the press-bonding, extrudes from the rear end of the substrate by a predetermined width; and cutting the dry resist film again at a position inside the rear end of the substrate prior to separating the base film after the dry resist film has been press-bonded so as to eliminate the portion of the dry resist film extruding from the substrate.

  • Patent number: 4102070
    Abstract: A display device is provided with a plurality of flip display cards which are pivotally carried by a rotatable card holder. A release tab is positioned above the card holder so as to engage the edge of one card whereby the information on the front of said one card can be viewed. The preceding card is supported on abutments on the card holder so that information on the back of said preceding card can be viewed simultaneously with the information on the front of said one card. The card holder is turned step-by-step so as to urge the one card past a first viewing position whereupon the card falls down onto the abutments for viewing in the second viewing position as the next card is moved into said first viewing position. The card holder has structure for pivotally carrying display cards, abutments for supporting display cards and indexing detents for providing the step-by-step advance of the display cards.
