Abstract: A thermostatically controlled bypass valve for bypassing water away from a hot water valve until the water temperature reaches a desired level at a fixture in use for home or industrial applications. The bypass valve has a valve body with a thermally sensitive actuator disposed between the hot water inlet and discharge ports and the cold water inlet and discharge ports that is thermally responsive to the temperature of the water. A bias spring pushes against the piston on the thermal actuator to close the actuator and open a passage between the cold and hot water sides when water needs to be bypassed. When the water from the hot water heater reaches the desired temperature level at the bypass valve, the bypass valve closes and hot water is made available to the hot water side of the fixture. Until then, the thermal actuator remains open and cold or tepid water is allowed to bypass the hot water side of the fixture.

Abstract: The present invention dispenses hot coffee or other beverage by the cup at a selected temperature, which can be varied from cup-to-cup. The beverage is brewed in a conventional way, and in one embodiment is stored in a conventional holding tank at elevated temperature. The holding tank communicates with two smaller reservoirs. A quantity of beverage is stored in a first reservoir at an elevated temperature, at or above the maximum desired dispensing temperature. A second quantity of beverage is cooled and stored in a second reservoir at a lower temperature, at or below the minimum desired dispensing temperature. When a cup of beverage is to be dispensed, the temperature is selected, and a quantity of beverage is dispensed from each of the reservoirs, proportioned so that the resulting dispensed beverage is at the selected temperature. In another embodiment, the first reservoir is omitted, and beverage from the holding tank provides the elevated temperature beverage for mixing.
