Abstract
Abstract Apparatus for controlling a mixer for dispensing multicomponent material wherein the component materials are supplied substantially continuously in controlled ratio in a substantially concurrent mixing and dispensing cycle, by metering means having transducing means operatively connected thereto. The apparatus includes means to control the supply of a second component in a predetermined ratio to a first component, incorporating transducing means energized at a level to reflect said ratio information and wherein the outputs of transducing means operatively connected to said first and second component metering means may be directly compared as being in the same order of magnitude to a generated control signal to directly control metering of said second component material.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
202 words
In apparatus for dispensing a multicomponent composition provided by the mixing together of at least two components in predetermined ratio in a mixing chamber including means for supplying a first component to said chamber, means for supplying a second component to said chamber, means for metering said first component supplied to said chamber, and means for metering the second component supplied to said chamber, a component ratioing control means comprising: a. means driving said first component supply means at a predetermined value; b. means generating a signal directly proportional to said metered first component; c. means generating a signal directly proportional to the predetermined ratio of said first component to said second component; d. means biasing said second component metering means with said predetermined ratio signal; e. means for generating a signal directly proportional to said ratio biased, metered second component; f. means for directly comparing said first component metering signal and said second component ratio biased metering signal; g. means for generating an error signal directly proportional to the difference between said compared signals; and h. means for driving one of said component supply means responsive to said error signal in a manner which tEnds to reduce said error to zero.
Claim 2
Dependent Claim

In apparatus for dispensing a multicomponent composition provided by the mixing together of at least two components in predetermined ratio in a mixing chamber including means for supplying a first component to said chamber, means for supplying a second component to said chamber, means for metering said first component supplied to said chamber, and means for metering the second component supplied to said chamber, a component ratioing control means comprising: a. means driving said first component supply means at a predetermined value; b. means generating a signal directly proportional to said metered first component; c. means generating a signal directly proportional to the predetermined ratio of said first component to said second component; d. means biasing said second component metering means with said predetermined ratio signal; e. means for generating a signal directly proportional to said ratio biased, metered second component; f. means for directly comparing said first component metering signal and said second component ratio biased metering signal; g. means for generating an error signal directly proportional to the difference between said compared signals; and h. means for driving one of said component supply means responsive to said error signal in a manner which tEnds to reduce said error to zero.
Claim 3
Dependent Claim
34 words
Apparatus according to claim 1 wherein the component drive means responsive to said error signal is driven according to a value representing the sum of said error signal and a predetermined nominal driving value.
Claim 4
Dependent Claim
179 words
A control system for apparatus for mixing and dispensing a multicomponent composition provided by the mixing together of at least two component ingredients in a mixing chamber including means for supplying a first component to said chamber, means for supplying a second component to said chamber, means for metering the first component supplied to said chamber, means for metering the second component supplied to said chamber, said control system comprising: a. transducer means for generating a signal directly proportional to the first component metered; b. transducer means for generating a signal proportional to the second component metered; c. means for generating a signal directly proportional to the ratio of said first component to said second component; d. means for biasing said second transducer means with said predetermined ratio signal; e. means for generating a signal directly proportional to the difference of said first transducer signal and said biased second transducer signal; and f. means for controlling the supply of one of said components responsive to the differential signal in a manner which tends to reduce said difference to zero.
Claim 5
Dependent Claim
179 words
A control system for apparatus for mixing and dispensing a multicomponent composition provided by the mixing together of at least two component ingredients in a mixing chamber including means for supplying a first component to said chamber, means for supplying a second component to said chamber, means for metering the first component supplied to said chamber, means for metering the second component supplied to said chamber, said control system comprising: a. transducer means for generating a signal directly proportional to the first component metered; b. transducer means for generating a signal proportional to the second component metered; c. means for generating a signal directly proportional to the ratio of said first component to said second component; d. means for biasing said second transducer means with said predetermined ratio signal; e. means for generating a signal directly proportional to the difference of said first transducer signal and said biased second transducer signal; and f. means for controlling the supply of one of said components responsive to the differential signal in a manner which tends to reduce said difference to zero.
