Abstract: An overflow prevention dispensing container comprising a portable container having at least one handle means, a nozzle, at least one air vent, at least one liquid fill aperture, and fill aperture cover; a dispensing handle having a valve mechanism; and at least one release; an automatic shutoff sensing means for sensing the level of fluid in a receiving tank and stopping the flow of liquid into the receiving tank when it is full, whereby the container is placed in a position to dispense liquid to the receiving tank, the operator activates the dispensing handle allowing liquid to freely flow into the receiving tank until the apparatus senses the level of the liquid in the receiving tank to be desired level at which time the flow will automatically be stopped.

Abstract: A circuit responsive to an input signal having an unspecified frequency for converting it to a predetermined and constant means frequency, and particularly suitable for incorporation in a modulation measuring instrument, comprises a sampling mixer controlled by a variable frequency oscillator for sampling the input signal to produce an intermediate signal. The mean frequency of the intermediate signal is then compared with a reference representing a predetermined frequency value whereby to produce an error signal, and means responsive to the error signal adjusts the frequency of the oscillator in such a direction as to tend to hold the mean value of the frequency of the intermediate signal at the predetermined frequency value while preserving therein variations in amplitude and/or frequency due to amplitude and/or frequency modulation.
