Abstract: A dispenser for a carbonated beverage bottle that uses the pressure from gases released by the beverage to eject the beverage. A plunger is depressed to unseat a check-ball floating in the beverage in a pick-up tube inside the bottle, the check-ball having been seated by gaseous and/or buoyant pressure in a seal to prevent escape of the gas or beverage. The neck and spout of the plunger are hollow, forming a passageway for the beverage to an opening in the spout. Beverage enters the neck of the plunger through opening in the circumferential wall of the neck when the plunger is depressed. Ribs on the interior wall of the seal are in frictional contact with the neck to prevent escape of the gas and the beverage. A tear-away collar permits stacking of the bottles and provides tamper resistance.

Abstract: A compressed single side band communication system and method in which the audio signal is compressed prior to pre-emphasis and thereafter summed with a pilot tone for further compression prior to transmission. Initially, only the pilot tome is transmitted at full rated power to aid in acquisition of the signal by the receiver. Thereafter, the transmitter ALC is disabled and the pilot tone is attenuated. The receiver adjusts the frequency characteristics of the pilot tone filter and phase lock loop filter in the detector as a function of lock-up. The delay after loss of lock-on in reverting to wide band pilot tone and wideband loop filters is varied as a function of signal strength. The pilot tone may be frequency modulated for tone coded squelch, with the modulating source being located in the return end of the phase lock loop filter. A unique filter is provided to insure acquisition of the pilot tone.
