Abstract: METHOD OF AND APPARATUS FOR MODIFYING A VIDEO SIGNAL      TO INHIBIT RECORDING THEREOF     Abstract of the Disclosure Video signal lines are added to or omitted from the ends of individual fields of a video signal to produce a modified video signal whose field length varies at a slow rate.  The modified video signal can be broadcast and received by conventional television equipment, normal television reception and viewing being not noticeably affected by the variable field length.  However, recording of the modified video signal is inhibited because the field length is not constant.  The modified video signal is produced by directly modifying the scanning of televising equipment, or by storing the lines of the video signal in a store and reading them in a controlled manner therefrom.  A decoder, for producing a constant field length video signal from the modified video signal, is also disclosed.     -i-

Abstract: Abstract of the Disclosure A cold drink vendor in which a circuit employing a programmed microcomputer controls the drink dispensing procedures and can be easily set to vary drink size, amount of ice to be dispensed, carbonation levels of each selection and the mix of the syrup and water for each selection.   The circuit is based on a constant flow rate variable time method of dispensing the beverage.  Initially, switch banks set by a service person are interrogated to determine the size of the drink and amount of ice to be dispensed, and the time cycle to dispense the drink is adjusted accordingly.   Upon the establishment of credit and the actuation of a selection switch, additional switchbanks are interrogated to determine whether the beverage selected is high carbonated, low carbonated or non-carbonated, and to determine when to start the corresponding syrup pump, in accordance with the syrup viscosity, and the drink is dispensed.
