  • Device for and method of real-time simulation of atmospheric effects on an image
    Patent number: 5663832
    Abstract: The present invention discloses a device for and method of simulating an image in real time under turbulent atmospheric conditions. The present invention is realized by expanding a first laser beam using a microscope-objective and a first lens. The expanded light is then projected onto a first LCLV. Light reflecting from the first LCLV is filtered, focused onto a diaphram, polarized, and directed along a path that is around two meters in length. The light is then split into a first beam and a second beam. The first beam is focused onto an optical fiber bundle which is connected to the first LCLV. One end of the optical fiber bundle is rotated with respect to the other end. The second beam is projected upon a second LCLV. A second laser beam is expanded and projected onto a LCTV. The image is provided to the LCTV. The LCTV image is projected onto, and modulated by the second LCLV.

  • Multi-material ripper tip
    Patent number: 3984910
    Abstract: A multi-material earthworking ripper tip having a leading nose portion comprised of a material having greater wear resistance and strength at elevated temperatures than the material which comprises the rearward shank supporting portion of the tip. In one embodiment, a bi-metallic nose portion is inertial welded to the shank support portion of the tip. In another embodiment powdered tungsten carbide is sintered in situ within a hollow bore of a steel nose portion. Alternately, a solid core of tungsten carbide could be soldered, brazed or press fitted within said hollow bore.
