Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
169 words
A continuous processor for treating material, comprising an elongate, closed tubular chamber means having inlet means at one end thereof for introducing a material into the tubular chamber means and outlet means at the other end of the tubular chamber means for discharging material from the chamber means, powered conveying means in said chamber means for treating material therein and for causing the material to flow from the inlet to the outlet, and adjustable restrictor means in said tubular chamber means between the inlet and outlet thereof for regulating the flow of material through said chamber means, said restrictor means comprising an apertured restrictor plate fixed transversely in said tubular chamber and adjustable gate means adjacent said apertured restrictor plate and movable relative thereto to control the flow of material through said apertured restrictor plate to control the time required for flow of the material through the tubular chamber to thus regulate the extent of the treatment of the material during its movement from the inlet to the outlet.
Claim 2
Dependent Claim
169 words
A continuous processor for treating material, comprising an elongate, closed tubular chamber means having inlet means at one end thereof for introducing a material into the tubular chamber means and outlet means at the other end of the tubular chamber means for discharging material from the chamber means, powered conveying means in said chamber means for treating material therein and for causing the material to flow from the inlet to the outlet, and adjustable restrictor means in said tubular chamber means between the inlet and outlet thereof for regulating the flow of material through said chamber means, said restrictor means comprising an apertured restrictor plate fixed transversely in said tubular chamber and adjustable gate means adjacent said apertured restrictor plate and movable relative thereto to control the flow of material through said apertured restrictor plate to control the time required for flow of the material through the tubular chamber to thus regulate the extent of the treatment of the material during its movement from the inlet to the outlet.
Claim 3
Dependent Claim
33 words
A continuous processor as in claim 1, wherein said powered conveying means includes a plurality of mixing blades mounted on rotatable shaft means in said chamber means for rotation in said chamber means.
Claim 4
Dependent Claim
21 words
A continuous processor as in claim 2, wherein said restrictor means is mounted in said chamber means between adjacent mixing blades.
Claim 5
Dependent Claim
35 words
A continuous processor as in claim 3, wherein adjustment means is connected to said adjustable gate means and extends externally of said chamber means for adjustment of said gate means from outside said chamber means.
Claim 6
Dependent Claim
27 words
A continuous processor as in claim 4, wherein said restrictor plate conforms in size and shape to the cross sectional size and shape of the chamber means.
Claim 7
Dependent Claim
33 words
A continuous processor as in claim 5, wherein a plurality of apertures extend through said restrictor plate; and said gate means includes means adjacent each aperture for adjusting the size of each aperture.
Claim 8
Dependent Claim
40 words
A continuous processor as in claim 6, wherein said chamber means has a substantially figure-eight cross-sectional configuration, said restrictor plate has a corresponding figure-eight configuration, and said gate means includes a pair of adjacent gates connected together for simultaneous movement.
Claim 9
Dependent Claim
61 words
A continuous processor as in claim 7, wherein a pair of shafts extend through the chamber means in parallel side-by-side relationship, a gate rotatably mounted on each shaft, said adjustment means connected to one of said gates for rotating said one gate, and interengaged means on said gates for effecting adjustment of the other gate upon adjustment of said one gate.
Claim 10
Dependent Claim
39 words
A continuous processor as in claim 8, wherein said interengaged means comprises a plurality of gears on a peripheral portion of each gate, rotation of one gate in one direction causing like but opposite rotation of the other gate.
Claim 11
Dependent Claim
47 words
A continuous processor as in claim 9, wherein each gate has a plurality of radially extending vanes thereon in cooperative association with a respective aperture so that rotary movement of said gates causes said vanes to move relative the apertures to control the Size of the apertures.
Claim 12
Dependent Claim
45 words
A continuous processor as in claim 10, wherein said adjustment means includes a link pivotally connected at one end to a peripheral portion of said one gate and pivotally connected at the other end thereof to a reciprocable adjustment rod extending externally of said chamber.
Claim 13
Dependent Claim
31 words
A continuous processor as in claim 11, wherein said adjustment rod is threaded and is threadably received through a stationary nut so that rotation of said rod effects axial movement thereof.
Claim 14
Dependent Claim
23 words
A continuous processor as in claim 12, wherein the apertures are trapezoidal in shape and the vanes on the gates are similarly shaped.
Claim 15
Dependent Claim
129 words
A continuous processor for treating material comprising elongate tubular chamber means, inlet means at one end of said chamber means for introducing a material into the chamber means, outlet means at the other end of the chamber means for discharging material from the chamber means, means in said chamber means for treating material therein and for causing the material to flow from the inlet to the outlet, and adjustable restrictor means in said chamber means between the ends thereof for regulating the flow of material through said chamber means, said restrictor means comprising a restrictor plate fixed transversely in said chamber and having a plurality of apertures therethrough, and adjustable gate means adjacent said restrictor plate, said gate means including means adjacent each aperture for adjusting the size thereof.
Claim 16
Dependent Claim
129 words
A continuous processor for treating material comprising elongate tubular chamber means, inlet means at one end of said chamber means for introducing a material into the chamber means, outlet means at the other end of the chamber means for discharging material from the chamber means, means in said chamber means for treating material therein and for causing the material to flow from the inlet to the outlet, and adjustable restrictor means in said chamber means between the ends thereof for regulating the flow of material through said chamber means, said restrictor means comprising a restrictor plate fixed transversely in said chamber and having a plurality of apertures therethrough, and adjustable gate means adjacent said restrictor plate, said gate means including means adjacent each aperture for adjusting the size thereof.
