Abstract
Abstract A draft beer circuit for a series of rapidly intermittent pours, in which a flow pressure control valve is introduced between the beer keg and the spigot, adjacent the spigot, to effectively isolate the downstream portion of the beer circuit below the pressure control valve from the upstream portion, except during conditions of flow. The pressure of the fluid at the spigot is thereby maintained at flow pressure rather than spigot pressure, so that all timed pours are of constant volume.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
116 words
Apparatus for automatic controlled dispensing of successive pours of draft beer, subject to foaming as it is dispensed comprising, in combination; a source of draft beer under pressure, a flow line connecting with said source a spigot valve connected with said flow line, a flow pressure control valve positioned in said flow line adjacent said spigot valve, power means for operating said flow pressure control valve and said spigot valve, timer means operatively connected with said power means, adapted to operate successively intermittently said spigot valve and said flow pressure control valve substantially simultaneously, and switch means operatively connected with said timer means whereby the operator may initiate and terminate the cycle of said successive pours.
Claim 2
Dependent Claim
116 words

Claim 3
Dependent Claim
45 words
Apparatus for automatic controlled dispensing of successive pours of draft beer according to claim 1 in which said timer means includes control means for varying the time period during which said spigot valve and said flow pressure control valve remain open and remain closed, respectively.
Claim 4
Dependent Claim
35 words
Apparatus for automatic controlled dispensing of successive pours of draft beer according to claim 1 in which a receiver is positioned in said flow line intermediate said spigot valve and said flow pressure control valve.
Claim 5
Dependent Claim
35 words
Apparatus for automatic controlled dispensing of successive pours of draft beer according to claim 2 in which a receiver is positioned in said flow line intermediate said spigot valve and said flow pressure control valve.
