Abstract
Abstract A method of dispensing at a tap an effervescent liquid from a keg-like supply comprises the steps of generally continuously monitoring the weight of the supply and generating an output corresponding thereto, collecting at the tap the liquid that overflows from a vessel into which it is being dispensed, weighing the collected overflow liquid and generating an output corresponding to this weight, comparing the outputs and calculating the difference therebetween, and periodically recording the difference.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
148 words
A method of dispensing at a tap an effervescent liquid from a keg-like supply, the method comprising the steps of: monitoring the initial weight of said keg-like supply of effervescent liquid; dispensing said supply into at least one vessel having a preset volume; generally continuously monitoring the weight of the supply after the dispensing into said at least one vessel and generating an output corresponding thereto; collecting at the tap any liquid that overflows from a vessel into which it is being dispensed; weighing the collected overflow liquid and generating an output corresponding to this weight; comparing the outputs and calculating the difference therebetween; periodically recording the difference comparing said difference with respect to the initial weight and number of vessels filled; and generating a problem signal when said difference deviates from said initial weight less the calculated weight of liquid dispensed into the number of vessels filled.
Claim 2
Independent Claim
148 words
A method of dispensing at a tap an effervescent liquid from a keg-like supply, the method comprising the steps of: monitoring the initial weight of said keg-like supply of effervescent liquid; dispensing said supply into at least one vessel having a preset volume; generally continuously monitoring the weight of the supply after the dispensing into said at least one vessel and generating an output corresponding thereto; collecting at the tap any liquid that overflows from a vessel into which it is being dispensed; weighing the collected overflow liquid and generating an output corresponding to this weight; comparing the outputs and calculating the difference therebetween; periodically recording the difference comparing said difference with respect to the initial weight and number of vessels filled; and generating a problem signal when said difference deviates from said initial weight less the calculated weight of liquid dispensed into the number of vessels filled.
Claim 3
Dependent Claim
21 words
The dispensing method defined in claim 1, further comprising the step of: recording the weight outputs whenever the supply is changed.
Claim 4
Dependent Claim
28 words
The dispensing method defined in claim 1, further comprising the step of: recording the weight of each supply and of the overflow liquid at each tap shift change.
Claim 5
Dependent Claim
25 words
The dispensing method defined in claim 1, further comprising the steps of: recording all of the weight outputs whenever power to the unit is interrupted.
Claim 6
Dependent Claim
39 words
The dispensing method defined in claim 1, further comprising the steps of: monitoring the temperature of the beer of the supply, and generating a problem signal when the supply temperature is outside a predetermined safe range for that beer.
Claim 7
Dependent Claim
34 words
The dispensing method defined in claim 1, further comprising the step of: diverting the overflow liquid and not weighing it except when the liquid is being dispensed and for a predetermined short time thereafter.
