  • Liquid dispensing apparatus and method by sensing the type of liquid vapors in the receiver
    Patent number: 5209275
    Abstract: The invention relates to a liquid dispensing apparatus which includes a detecting element for detecting the liquid from the vaporized gas surrounding the remaining liquid in a storage tank to be supplied, where the detecting element is disposed at the output end of a liquid supply line, and a discriminator for discriminating the signals and information obtained from such a detecting element. The discriminator generates a lock signal to be fed to a locking means for allowing suspension of the supply of liquid based on a signal generated in the discriminator and fed to the locking means. The detection element includes a first electrode, a second electrode, a gas-sensing member connected to the first electrode and connected to the second electrode, which gas-sensing member is formed of a resin material including a conducting material which furnishes an impedance change upon contacting the vaporized gas of the liquid to be detected.

  • Floating oil leak detector
    Patent number: 4549171
    Abstract: Oil floating on the surface of a body of water can be detected by the floating sensor of this invention which comprises a float having a central opening vertically therethrough and containing an electrical sensor, the lead wire connected to the sensor extending downwardly through the opening, forming a U-bend and extending upwardly through the opening to alarm means. A weight at the U-bend provides for automatic height adjustment of the detector as the surface of the body of water raises or lowers.
