  • Apparatus for detecting metallic particles in a flow of dielectric medium
    Patent number: 4004216
    Abstract: An apparatus for detecting the presence of metallic particles in a flow of dielectric material is based upon the principle of measuring the frequency shift of an oscillator upon passage of such a particle through the self induction coil forming part of said oscillator. Special arrangements are provided for rendering the magnetic field as uniformly as possible within the coil so that the magnitude of the signal is not subject to significant fluctuations whether the particle passes through the center of the self-induction coil or not.
    Type: Grant

  • Method and device for testing a chain link mechanism
    Patent number: 3972221
    Abstract: A device for testing an endless chain-link mechanism comprises a disc, mounted to a DC-servomotor, which is resiliently urged against the rollers which serve to support the chain-link. The current of the motor is recorded in function of time and the significant part which is a measure of the resistance to rotation is determined. When this value exceeds a predetermined one, the roller is considered to be defective. Auxiliary circuits for signal processing may be provided, if desired.
