Abstract: An improved water heater is proved, particularly for marine use, wherein a heated liquid, such as engine coolant, flows to a heat exchanger in a water tank to heat the water therein. The improvement comprises a check valve assembly in the engine coolant line to control the flow of coolant to the heat exchanger, and thereby control the temperature of the water. As the water temperature increases, the check valve moves towards a closed position to reduce and ultimately stop the flow of heated engine coolant to the heat exchanger. As the water temperature decreases, the poppet valve moves toward and open position, so as to increase the flow of engine coolant to the heat exchanger, and thereby further heat the water. The water temperature is sensed by a wax actuator within the check valve which expands in response to increased water temperatures and contracts in response to decreased water temperatures.

Abstract: The present invention relates to a portable adhesive dispensing appliance with adjustable duty cycle. Rather than applying power continuously to the heating element, the element power is intermittently switched over to a variable duty cycle. Savings are gained in three areas: extended life of the element; less heat lost to thermal radiation; and less adhesive waste due to dripping and overheating. The duty cycle may be adjusted manually or automatically based on the temperature of the adhesive in the melt chamber. Additionally, the voltage and/or current to the heating element may be adjusted, either manually or automatically, for more rapid recovery during high usage periods. Higher throughput is achieved by sensing the temperature, comparing the temperature to a desired temperature, and then increasing the duty cycle by either or both one of increasing the frequency of duty pulses and/or lengthening the duration of the duty pulses.
