  • Patent number: 5431302
    Abstract: An improved apparatus and method is provided for accurately dispensing a preselected volume of liquid. A flowmeter is provided to generate signals proportional to the flow of liquid through a faucet. A programmed microcomputer receives the flowmeter signals and controls the faucet. The residual volume of liquid (spill), which was dispensed after the faucet was last commanded to close, is stored and averaged with additional, previously stored spill amounts by the microcomputer. The average spill volume is used to anticipate the spill for the forthcoming pour. When the cumulative volume of liquid dispensed is equal to the preselected volume less the anticipated spill volume, the microcomputer signals the faucet to close, resulting in an accurate pour. In a another aspect, an improved beer dispensing head is provided. A spring-loaded conventional tap handle activates a sensor means in the head.

  • Patent number: 4985916
    Abstract: A telephone subscriber interface device provides privacy on a party line. The device provides for revertive calling, break-in, automatic disconnect, selective ringing, automatic number identification, and operates on the central office power supply. The device provides the following features: A connect state for the PLC in which the PLC is connected to the telephone line but in which the PLC is not responsive to other inputs, a ring decoder which detects either divided coded ringing signals or divided ringing signals in a novel manner, means for testing whether a revertive call has been properly terminated, a low power switch so that the PLC can run on telephone line power only without battery backup, and means for resetting the PLC to a ready state in the absence of other inputs.
