1. A programmable portion controlled liquid dispensing valve, comprising:
- at least one selection switch for selecting the dispensing of a programmed liquid volume,control means for controlling the dispensing of the programmed volume in response to the operating of the selection switch, the control means having a dispensing mode for dispensing the programmed liquid volume and a programming magnetically operable mode for permitting the changing of the programmed liquid volume to a different liquid volume value, andmode switch means for switching the control means between the dispensing mode and the programming mode, the mode switch means responsive to a magnetic field so that the mode switch means is operable without requiring any direct physical contact therewith.

Abstract
A method and apparatus for dispensing beverage with programmable electronic portion control of one or more serving sizes has the steps of and apparatus for placing a discrete magnet adjacent the electronic control, the control having a reed switch which changes state under influence of the field of the magnet and switches the control from a normal select and dispense mode to an alternative hold and program mode.

6. A programmable portion controlled liquid dispensing valve, comprising:
-
at least one selection switch for selecting the dispensing of a programmed liquid volume, control means for controlling the dispensing of the programmed volume in response to the operating of the selection switch, the control means having a dispensing mode for dispensing the programmed liquid volume and a programming mode for permitting the changing of the programmed liquid volume to a different liquid volume value, and magnetically operable mode switch means for switching the control means between the dispensing mode and the programming mode, the mode switch means responsive to a magnetic field so that the mode switch means is operable without requiring any direct physical contact therewith, and the valve having an outer housing and the mode switch means located within the housing and the housing being formed at least in part of a magnetically transparent material to permit operating of the mode switch means by the magnetic field. - View Dependent Claims (7, 8, 9)

10. A method of programming a programmable portion controlled liquid dispensing valve, the valve having at least one selection switch for selecting the dispensing of a programmed liquid volume, and having control means for controlling the dispensing of the programmed volume in response to the operating of the at least one selection switch, the control means having a dispensing mode for dispensing the programmed liquid volume and a programming mode for permitting the changing of the programmed liquid volume to a different liquid volume value, and the valve further including mode switch means for switching the control means between the dispensing mode and the programming mode, the mode switch means responsive to a magnetic field so that the mode switch means is operable without requiring direct physical contact therewith, the method comprising the steps of:
- providing a magnetic field of sufficient strength in the vicinity of the mode switch means for operating thereof for placing the control means in the programming mode, operating the at least one selection switch for a desired length of time for creating a new programmed dispensing volume, and magnetically affecting the mode switch means for returning the control means to the dispensing mode.
