Pneumatically controlled dispensing system

Claim 2

A pneumatically controlled dispensing system wherein the strokes of an air-operated fill pump, which is adapted to deliver a predetermined amount of fill material on each directional stroke, are sensed and a flow valve at a fill station is thereby controlled, which dispensing system comprises: (a) air-operated signal means for sensing each stroke of said pump and for producing an air pulse corresponding to each said stroke; (b) Air-operated counter means for counting each said air pulse produced by said signal an air pressure response signal after receiving a predetermined number of said air pulses; (c) flow valve means movable between a first and a second position for directing the flow of fill material delivered thereto from said pump between a first and a second outlet line; and (d) actuator means operated by said response signal of said counter means means for moving said valve means between said first and second positions.

Claim 3

A pneumatically controlled dispensing system in accordance with claim 3 wherein said flow valve means is a three-way bass valve.

Claim 4

A pneumatically controlled dispensing system wherein the strokes of an air-operated fill pump, which is adapted to deliver a predetermined amount of fill material on each directional stroke, are sensed and a flow valve at a fill station is thereby controlled, which dispensing system comprises: (a) air-operated signal means for sensing each stroke of said pump and for producing an air pulse corresponding to each said stroke; (b) a first and a second air-operated counter means for counting each said air pulse produced by said signal means, wherein said first counter produces a first air pressure response signal after receiving a predetermined number of said air pulses and said second counter is adapted to produce a second air pressure response signal spaced from said first air pressure response signal by one-half the number of said predetermined number of said air pulses; (c) flow valve means movable between a first and a second position for directing the flow of fill material delivered thereto from said pump between a first and a second outlet line, and; (d) actuator means operated by said first and second air pressure response signals of said first and second counter means for moving said valve means between said first and and second positions.

Claim 5

A pneumatically controlled dispensing system wherein the strokes of an air-operated fill pump, which is adapted to deliver a predetermined amount of fill material on each directional stroke, are sensed and a flow valve at a fill station is thereby controlled, which dispensing system comprises: (a) air-operated signal means for sensing each stroke of said pump and for producing an air pulse corresponding to each said stroke; (b) a first and a second air-operated counter means for counting each said air pulse produced by said signal means, wherein said first counter produces a first air pressure response signal after receiving a predetermined number of said air pulses and said second counter is adapted to produce a second air pressure response signal spaced from said first air pressure response signal by one-half the number of said predetermined number of said air pulses; (c) flow valve means movable between a first and a second position for directing the flow of fill material delivered thereto from said pump between a first and a second outlet line, and; (d) actuator means operated by said first and second air pressure response signals of said first and second counter means for moving said valve means between said first and and second positions.

Claim 6

A pneumatically controlled dispensing system in accordance with claim 1 wherein said flow valve means is a three-way ball valve.

Claim 7

A pneumatically controlled dispensing system wherein the strokes of an air-operated fill pump, which is adapted to deliver a predetermined amount of fill material on each directional stroke, are sensed and a flow valve at a fill station is thereby controlled, which dispensing system comprises: (a) a first and a second air-operated counter means for sensing and counting each directional stroke of said pump, wherein said pump is operated with air having a pressure greater than required to operated said first and second counter means, and wherein said first counter produces a first air pressure response signal after sensing a predetermined number of said directional strokes and said second counter means is adapted to produce a second air pressure response signal spaced from said first air pressure response signal by one-half the number of said predetermined number of said directional strokes; (b) flow valve means movable between a first and a second position for directing the flow of fill material delivered thereto from said pump between a first and a second outlet line. and (c) actuator means operated by said first and second air pressure response signals of said first and second counter means for moving said valve means between said first and second positions.

Claim 8

A pneumatically controlled dispensing system wherein the strokes of an air-operated fill pump, which is adapted to deliver a predetermined amount of fill material on each directional stroke, are sensed and a flow valve at a fill station is thereby controlled, which dispensing system comprises: (a) a first and a second air-operated counter means for sensing and counting each directional stroke of said pump, wherein said pump is operated with air having a pressure greater than required to operated said first and second counter means, and wherein said first counter produces a first air pressure response signal after sensing a predetermined number of said directional strokes and said second counter means is adapted to produce a second air pressure response signal spaced from said first air pressure response signal by one-half the number of said predetermined number of said directional strokes; (b) flow valve means movable between a first and a second position for directing the flow of fill material delivered thereto from said pump between a first and a second outlet line. and (c) actuator means operated by said first and second air pressure response signals of said first and second counter means for moving said valve means between said first and second positions.
