  • Patent number: 5123893
    Abstract: A passive paper stacker for a printer is disclosed which is able to stack a series of pages of a Z-fold paper web, each page having a length L and a width W. The stacker includes a tray that extends from a surface of the printer. The paper web, as it exits from the printer intersects that surface. A ramp is provided to receive the paper web and has both proximal and distal ends, the proximal end receiving the paper web as it exits from the printer and the distal end positioned closer to the tray than the proximal end and at a distance from the printer surface that is at least equal to L/2. First and second sets of chains define a paper web fall path from the distal end of the ramp to the base. The first set of chains are positioned between the distal end of the ramp and the printer surface and the second set of chains are positioned so as to place the distal end of the ramp between the second set of chains and the printer surface. A basket is positioned on the tray and receives the paper web.

  • Patent number: 4977843
    Abstract: Self locking apparatus for quick and convenient tensioning of the luff of a sail of a sailboard. In a first embodiment, the tack of the sail is attached to the mastbase close to the hull of the sailboard and the head of the sail is attached to the apparatus of the invention. The invention includes a cap for placement over and receiving the top of the sailboard mast, a lever pivotally engaging the cap; and an adjustment strap connecting the head of the sail to a cross bar on the lever. The lever brings the strap in a self locking position over center for tensioning the luff of the sail. In a second embodiment, the head of the sail is attached in conventional manner to the top of the mast and the lever is positioned by means of a sleeve to the bottom of the mast. Once again, the lever rotates to an over-center self-locking position for tensioning the luff of the sail.
