Abstract: A protection device for a waterbed protects the water bladder and water heater from damage due to overheating when a dangerous condition, such as an insufficient level of water within the bladder or an element of the waterbed surroundings interposed between the bladder and the water heater, arises. The protection device employs a detector in the form of two capacitance plates placed adjacent to the water bladder and connected to a circuit which is operative to prevent power from being supplied to the water heater upon detection of a dangerous condition. The capacitance of the detector plates varies with the level of the water within the bladder and with the presence of a surrounding element between the bladder and heater.

Abstract: The present invention includes a method of enhancing the flavor of synthetic chewing gum base by the addition of a minor amount of cocoa powder to the base itself or to the chewing gum in which the base is used. Whether the cocoa powder is added to the gum base or to the chewing gum, the amount of cocoa powder should be between about 0.3 and 2.4 percent by weight of the gum base. The invention also includes the synthetic chewing gum base or a chewing gum with a synthetic gum base with cocoa powder added in a minor amount to enhance the flavor of the gum base. The synthetic gum base of the present invention is substantially free of natural gum products and includes between about 10 and about 30 percent of a synthetic elastomer; between about 20 and about 70 percent of a synthetic resin; and between about 0.3 and about 2.4 percent cocoa powder.
