Rectilinear Moving Scale Patents (Class 116/259)
  • Patent number: 7596846
    Abstract: A temporary fastener includes a grip length indicator. By machining a flattened area into a body of the temporary fastener, by engraving an scale into the flattened area, and by attaching an indicator dot visible in the groove to a moving part of an internal assembly of the temporary fastener, the grip length of the installed temporary fastener may be read directly on the scale while the temporary fastener applies a clamp-up force to a structure. By using the temporary fastener of the present invention, it is possible to determine a fastener hole length while a temporary fastener is installed. Using the method for determining a fastener grip length of the present invention enables the effective determination of the correct fastener grip length for each particular fastener hole of a large structure, such as an aircraft airframe.

  • Patent number: 4991519
    Abstract: An incinerating furnace which utilizes mineral particles as a hearth bed. Hearth particles are supplied and automatically flow down by gravity into the combustion chamber and onto a movable plane member, such as a rotary table, disposed at the bottom of the furnace. A mixture of used hearth particles and the combustion remainder is removed from the outlet of the furnace as the movable plane member moves and introduced into a receiving tank. Supplemental hearth particles are supplied from a hopper into the combustion chamber and form an oblique hearth bed where incineration takes place.

  • Patent number: 4528859
    Abstract: In a pointer sliding mechanism intended for use in a pushbutton tuner, there is fixed on the base plate of the tuner a pair of pivots, right and left, on which right and left links are pivotably mounted at the front ends thereof; a pointer mount-plate is pivotably mounted to the right and left links at the rear ends thereof so as to couple these links together. On the other hand, there is provided on the base plate of the pushbutton tuner a memory slide which is movable in the direction of the width of the tuner, and a V-shaped link is mounted between the memory slide and one of the links supporting the pointer mount-plate, which V-shaped link is freely openable and closable; the arm of this V-shaped link on the side of the memory slide is pivotably mounted at the central portion thereof to a pivot fixed to the base plate.
