  • Patent number: 5647055
    Abstract: A heated water apparatus which includes a reservoir for retaining a quantity of heated water and a controller for controlling the heated water apparatus. A controllable heater is coupled to the controller and the reservoir for controllably heating the water retained in the reservoir. A water sensor is coupled to the reservoir and to the controller for detecting the presence and absence of a desired quantity of water in the reservoir and providing a signal to the controller. The controller controls a water source which controllably admits water to the reservoir. The controller also controls an outlet valve coupled to the reservoir. The controller operates the inlet valve and the outlet valve to control the flow of water through the outlet valve in response to the presence and absence of water in the reservoir. When the water level is too low, the controller cycles the outlet valve for specific periods of time in order to allow the water level of the reservoir to catch up.

  • Patent number: 5611261
    Abstract: A spent beverage brewing substance disposal device for use with a beverage brewing apparatus. The disposal device is connected to the beverage brewing apparatus for receiving a slurry of spent beverage brewing substance and liquid. The disposal device includes a housing having a delivery port communicating with a drain conduit of the beverage brewing apparatus for receiving the slurry therethrough. A foraminous structure is retained in the housing and positioned for receiving the slurry. The foraminous structure allows a liquid portion to drain therethrough while retaining the solid or particulate matter of the slurry. A pressurizing apparatus is coupled to the housing of the disposal device so as to pressurize the interior chamber defined by the housing to expedite the separation of the liquid portion from the solid portion. Liquid which is drained from the slurry passes through the foraminous structure and into a drain.
