  • Windshield wiper sharpening device
    Patent number: 5359776
    Abstract: A device is provided for restoring the cleaning properties of worn vehicle windshield wiper blades. A notch in the body of the hand-held device accepts the working edge of the windshield wiper blade. A sharp steel blade recessed in the notch is thus placed in transverse contact with the working edge of the windshield wiper blade. As the device is drawn along the length of the windshield wiper blade, wiper blade material is removed as needed to restore its original sharp cross-section and smoothness, and hence, its cleaning ability.

  • Hot box detector bearing discriminator circuit
    Patent number: 4113211
    Abstract: An improved circuit is provided for differentiating between roller bearings and friction bearings in a railroad hot box detector system. The improved circuit integrates the waveform generated by a bearing scanner and compares that to the integral of a pre-selected portion of the waveform. By this method of comparison, irregularities in the system due to noise are obviated.
