  • Patent number: 7430934
    Abstract: This transmission utilizes an adjustable fulcrum to accomplish variable speed and torque conversion. The component utilizes multiple circular eccentric cams fixed to an input shaft at equal rotational intervals to apply vertical movement to an equal number of perpendicular torque converter shafts spanning the distance between the parallel input and clutch shafts. To provide control, yet allow for free horizontal and rotational movement, the torque converter shafts operate through separate sleeves attached to the cams and to a common adjustable fulcrum located between and parallel to the input and clutch shafts. Output ends of the torque converter shafts are attached, in a pinion fashion, to different unidirectional roller clutches mounted on the clutch shaft. These clutches can then, based upon adjustable fulcrum settings, translate modified cam movements into a wide range of rotary output motions with an infinite number of speed and torque ratios.

  • Patent number: 7061742
    Abstract: A manually operated continuous-use desk-top magnetic media eraser/degausser that utilizes elaborately shielded state-of-the-art Rare Earth Magnets to uniformly remove magnetically recorded information from audio and video tapes, PC diskettes, and many other types of magnetic media that can be accommodated by the component's 1.0625 inches high by 4.125 inches wide media transport pathway. The media, as it traverses the pathway, passes through a very strong magnetic field created by two powerful grade N40 (40 MGOe) patented neodymium (NdFeB) permanent magnets placed perpendicular and end-to-end under the center of said pathway. As the recorded media is manually manipulated through the pathway, over the magnets, and out the exit, magnetic information stored on said media is removed by the strong magnetic lines of force present within the protective triple-shielded top, bottom, and side components surrounding the transport pathway.
