Consistency responsive device

Claim 1

FOR USE IN AN APPARATUS FOR CONTINUOUSLY CONTROLLING THE CONSISTENCY OF A FLUENT MATERIAL CONSISTING OF AN ADMIXTURE OF SOLID MATTER AND A FREELY-FLOWING LIQUID, A CONSISTENCY RESPONSIVE DEVICE COMPRISING, A HOUSING HAVING ALIGNED INGRESS AND EGRESS OPENINGS IN SPACED RELATION ALONG THE LENGTH THEREOF FOR THE PASSAGE OF THE ENTIRETY OF THE FLUENT MATERIAL LENGTHWISE THERETHROUGH, A ROTATIVE TORQUE GENERATING SENSING DEVICE POSITIONED WITHIN THE ENVIRONMENT OF THE FLUENT MATERIAL WITHIN THE HOUSING AND BEING OPERATIVE IN A PLANE ON THE AXIS OF FLOW OF THE FLUENT MATERIAL THROUGH THE HOUSING FOR PRODUCING A COUNTERCLOCKWISE TORQUE PRODUCED BY THE SHEAR FORCE AS THE SENSING DEVICE IS ROTATED CLOCKWISE AND BEING RESPONSIVE TO CHANGES IN THE SHEAR FORCE REQUIRED TO MOTIVATE THE SENSING DEVICE THROUGH THE FLUENT MATERIAL ACCORDINGLY AS ITS CONCENTRATION IS VARIED COMPRISING: MOMENT BALANCING MEANS MOUNTED RELATIVE TO THE HOUSING FOR TRANSLATING THE RESPONSES TO THE CHANGES IN SHEAR FORCE AND BEING INCLUSIVE OF, A GEAR REDUCER MOTOR PIVOTALLY MOUNTED RELATIVE TO THE HOUSING AND HAVING A HORIZONTALLY-DISPOSED OUTPUT SHAFT EXTENDING INTO THE HOUSING AND A DRIVE SHAFT CONNECTED TO SAID OUTPUT SHAFT, SAID DRIVE SHAFT BEING DISPOSED ALONG A SUBSTANTIALLY VERTICAL AXIS WITH THE VERTICAL CENTRAL AXIS OF SAID DRIVE SHAFT AND MOTOR BEING OFFSET FROM THE VERTICAL CENTRAL AXIS OF SAID OUTPUT SHAFT WHEREFORE SAID MOTOR IS FREE TO ROTATE ABOUT THE AXIS OF SAID OUTPUT SHAFT, THE SENSING DEVICE BEING FIXED TO SAID OUTPUT SHAFT AND DRIVEN THEREBY AT A CONSTANT SPEED RATE, SAID MOTOR BEING PIVOTALLY MOVABLE ABOUT SAID OUTPUT SHAFT THEREOF TO DIFFERENT OFFSET POSITIONS ACCORDING TO CHANGES IN THE REQUIRED SHEAR FORCE ALLOWING A CLOCKWISE MOMENT OF RELATIVELY GREAT MAGNITUDE, A PAIR OF TORQUE ARMS FIXED TO SAID MOTOR, ONE OF SAID TORQUE ARMS CARRYING A COUNTER-WEIGHT SLIDABLY ADJUSTABLE TO SELECTED POSITION THEREALONG AND ALLOWING A COUNTER CLOCKWISE MOMENT FOR NORMALLY COUNTERACTING THE TORQUE REQUIRED TO ROTATE THE SENSING DEVICE, A COMPRESSIBLE SPRING MEANS, THE OTHER OF SAID TORQUE ARMS BEING LINKED TO SAID SPRING MEANS FOR ALLOWING A RELATIVELY SMALL CLOCKWISE MOMENT UPON COMPRESSION OF SAID SPRING MEANS, THE SUM OF THE CLOCKWISE MOMENTS OF THE OFFSET POSITIONING OF SAID MOTOR AND THE COMPRESSION OF SAID SPRING MEANS BEING OPPOSED BY THE SUM OF THE COUNTERCLOCKWISE MOMENT OF THE COUNTERWEIGHT OF THE ONE OF SAID TORQUE ARMS AND THE TORQUE PRODUCED BY THE SHEAR OF THE ROTATING SENSING DEVICE; A CONNECTING LINK, THE SAID OTHER OF SAID TORQUE ARMS BEING MECHANICALLY INTERCONNECTED TO SAID CONNECTING LINK.
