Abstract
Abstract The apparatus comprises a revolving cage (4) provided with two plates (20,21) effective to be rotated about the central axis whereof and to receive and hold a product vessel to be processed (33), and two electric motors (13,17) effective to rotate, individually and with a different transmission ratio, the cage driving pulley (10), the operation of either one or the other motor depending on the height of the product vessel (33) with respect to a threshold height.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
291 words
A mixing apparatus having a cage rotatable about its transversal axis, said cage including two plates rotatable about their central axes and adapted to receive and hold a product vessel therebetween, said plates including means for causing said plates to be selectively moved nearer with respect to one another and away from one another, a driven pulley rigid with said cage, said cage being rotated via said driven pulley, a fixed pulley, a belt passing on said fixed pulley, said plates being rotated via said belt passing on said fixed pulley and transmission pulleys on which said belt is slidable, said vessel rotating plate having a shaft, one of said transmission pulleys being rigid with said shaft of said vessel rotating plate, said mixing apparatus comprising two motors for rotating, individually and each with a different transmission ratio, said driven pulley, each of said motors having a shaft, the operation of one of said motors depending on the height of said product vessel with respect to a determined threshold height; a given diameter pulley; two additional pulleys of different diameters, said given diameter pulley and said additional pulleys being respectively mounted on said shafts of said motors; a belt on said given diameter pulley, the pulley of greater diameter of said pulleys of different diameters being coupled to said belt; an additional belt coupling the pulley of smaller diameter of said pulleys of different diameters to said driven pulley; and a photocell system for selectively energizing said motors, said photocell system comprising an electronic relay, an impinging light beam having a horizontal axis and a light detector controlling said relay, said light beam being blockable from impinging on said light detector by said product vessel, as clamped between said rotating plates.
Claim 2
Dependent Claim
291 words
A mixing apparatus having a cage rotatable about its transversal axis, said cage including two plates rotatable about their central axes and adapted to receive and hold a product vessel therebetween, said plates including means for causing said plates to be selectively moved nearer with respect to one another and away from one another, a driven pulley rigid with said cage, said cage being rotated via said driven pulley, a fixed pulley, a belt passing on said fixed pulley, said plates being rotated via said belt passing on said fixed pulley and transmission pulleys on which said belt is slidable, said vessel rotating plate having a shaft, one of said transmission pulleys being rigid with said shaft of said vessel rotating plate, said mixing apparatus comprising two motors for rotating, individually and each with a different transmission ratio, said driven pulley, each of said motors having a shaft, the operation of one of said motors depending on the height of said product vessel with respect to a determined threshold height; a given diameter pulley; two additional pulleys of different diameters, said given diameter pulley and said additional pulleys being respectively mounted on said shafts of said motors; a belt on said given diameter pulley, the pulley of greater diameter of said pulleys of different diameters being coupled to said belt; an additional belt coupling the pulley of smaller diameter of said pulleys of different diameters to said driven pulley; and a photocell system for selectively energizing said motors, said photocell system comprising an electronic relay, an impinging light beam having a horizontal axis and a light detector controlling said relay, said light beam being blockable from impinging on said light detector by said product vessel, as clamped between said rotating plates.
Claim 3
Dependent Claim
62 words
A mixing apparatus as claimed in claim 1, wherein said cage has a central bracket, a top plate and a bottom plate, each of said plates having spaced opposite ends, and a pair of column members coupling said top and bottom plates to each other at the corresponding ends of said plates, said bracket having a shaft coupled to said driven pulley.
Claim 4
Dependent Claim
87 words
A mixing apparatus as claimed in claim 2, further comprising a pair of movable plates, one above said bracket and the other under said bracket, said plates being slidable along said column members, each of said movable plates bearing a corresponding one of said rotatable plates, one of said rotatable plates being idly mounted on the corresponding one of said movable plates and the other of said movable plates having bearings supporting the shaft of the other of said rotatable plates, which is said vessel rotating plate.
Claim 5
Dependent Claim
76 words
A mixing apparatus as claimed in claim 3, wherein each of said column members has two columns, and further comprising a pair of threaded rods each located between the columns of a corresponding one of said column members, each of said threaded rods having opposite pitch threads at the upper and lower parts of said bracket and selectively moving said movable plates toward and away from each other, said bracket being centrally positioned in said cage.
Claim 6
Dependent Claim
62 words
A mixing apparatus as claimed in claim 4, wherein each of said threaded rods has a sprocket keyed at a corresponding end thereof, and further comprising gear pairs engaging corresponding ones of said sprockets and a gear wheel meshing with said gear pairs for rotating said threaded rods, said gear wheel having a drive arm affixed thereto for rotating said gear wheel.
Claim 7
Dependent Claim
34 words
A mixing apparatus as claimed in claim 5, wherein said rotatable plates are movable toward and away from each other via said gear wheel, said gear pairs, said threaded rods and said movable plates.
