Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
131 words
Measuring device for beverage-tapping apparatus having a feed line from a source of supply of the beverage and connected to said feed line, a measuring chamber, a volume measuring device with a meter connected thereto, and a value and valve outlet downstream of the measuring chamber, light sensing means positioned upstream of the measuring chamber adapted to distinguish foam from compact liquid, said volume measuring device having at least one rotating means which revolves proportionately to the beverage flow, said rotating means acting on impulse sender means which sends at least one impulse to electronic gate means with each rotation, said gate means being adapted to also receive a signal from the sensing means and then act upon said meter with impulses to be counted only when compact liquid is present.
Claim 2
Dependent Claim
131 words
Measuring device for beverage-tapping apparatus having a feed line from a source of supply of the beverage and connected to said feed line, a measuring chamber, a volume measuring device with a meter connected thereto, and a value and valve outlet downstream of the measuring chamber, light sensing means positioned upstream of the measuring chamber adapted to distinguish foam from compact liquid, said volume measuring device having at least one rotating means which revolves proportionately to the beverage flow, said rotating means acting on impulse sender means which sends at least one impulse to electronic gate means with each rotation, said gate means being adapted to also receive a signal from the sensing means and then act upon said meter with impulses to be counted only when compact liquid is present.
Claim 3
Dependent Claim
12 words
Measuring device of claim 1 wherein the sensing means is a photocell.
Claim 4
Dependent Claim
18 words
Measuring device of claim 2 wherein an infrared lamp as a source light is associated with the photocell.
Claim 5
Dependent Claim
26 words
Measuring device of claim 1 wherein said rotating means is a substantially cylindrical measuring chamber in which a rotating piston carrying an impulse center is positioned.
Claim 6
Dependent Claim
55 words
Measuring device of claim 1 wherein the measuring chamber is cylindrical with a centrally arranged carrier element around which a cylindrical piston rotates, a wandering hollow area being formed between the inside of said measuring chamber and the outside of said piston whereby a measured liquid volume is transported from an inlet to an outlet.
Claim 7
Dependent Claim
41 words
Measuring device of claim 5 wherein the measuring chamber inlet and outlet are separated by a wall and are periodically swept over during movement of the piston by the piston-cross-section area, said separation wall passing through a slit in the piston.
Claim 8
Dependent Claim
24 words
Measuring device of claim 1 wherein a permanent magnet is carried by the rotating means and a Hall-probe is positioned outside the measuring chamber.
Claim 9
Dependent Claim
27 words
Measuring device of claim 1 wherein the volume measuring device, the meter and the sensing means are built into a filling installation shaped like a tapping valve.
