Abstract: A meter is disclosed for measuring the dielectric constant of a particulate material, particularly grain, as a function of its moisture content. The meter includes a test cell for containing a sample of the particulate material to be tested. A single oscillator includes a variable frequency tuned circuit for varying the frequency of the single oscillator output. The tuned circuit includes a test cell capacitor using a sample of material to be tested as a dielectric, a calibrated variable standard capacitor and a variable trimming capacitor. An indicator is coupled to the calibrated variable standard capacitor to display a value representing the capacitance setting of the calibrated variable standard capacitor. A frequency monitor compares the output frequency of the oscillator with a selected frequency and a null display displays the difference between the output frequency of the oscillator and the selected frequency.

Abstract: An apparatus for the activation of a remote device having a transmitter to generate and transmit user-set special coded signals. The transmitter has a function selector switch to select modes of operation for the transmitter. Included is also a receiver to receive the user-set special coded signals, and the receiver also has a function selector switch to select modes of operation for the receiver. The function selector switch selects the following modes of operation for the transmitter: (a) a “transmit/fire” mode that enables a fire signal to be transmitted to the receiver; (b) a “wake-up” mode that enables a set-up receiver mode for immediate firing; (c) a program mode for low power transmission of programmed codes; and (d) a “test” and operational mode that enables an operational test of the apparatus with no firing output.
