Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
145 words
An apparatus for rotating a plurality of reaction vessels in an inclined posture, comprising: a first plate fastened on a shaft inclined to a horizontal plane and rotatable by a first driving means; a plurality of vessel holders disposed on a concentric circular line on said first plate and held rotatably thereon with their axes of rotation parallel to said shaft; a second plate supported rotatably on said shaft and rotatable by a second driving means at a speed independent of the speed of rotation of said first plate, said second plate being associated with said first plate in such a manner that rotation of said second plate causes rotation of said vessel holders about their said axes of rotation and a base fixing the shaft in such a manner that the reaction vessel holders may be inclined at an angle to the horizontal plane.
Claim 2
Independent Claim
145 words
An apparatus for rotating a plurality of reaction vessels in an inclined posture, comprising: a first plate fastened on a shaft inclined to a horizontal plane and rotatable by a first driving means; a plurality of vessel holders disposed on a concentric circular line on said first plate and held rotatably thereon with their axes of rotation parallel to said shaft; a second plate supported rotatably on said shaft and rotatable by a second driving means at a speed independent of the speed of rotation of said first plate, said second plate being associated with said first plate in such a manner that rotation of said second plate causes rotation of said vessel holders about their said axes of rotation and a base fixing the shaft in such a manner that the reaction vessel holders may be inclined at an angle to the horizontal plane.
Claim 3
Dependent Claim
65 words
The apparatus for rotating reaction vessels in an inclined posture according to claim 1, wherein said first and second plates are circular, said first and second driving means each comprises a motor and a gear train, and an outer periphery of said second circular plate contacts outer peripheries of said vessel holders whereby rotation of said second circular plate causes rotation of said vessel holders.
Claim 4
Dependent Claim
24 words
The apparatus for rotating reaction vessels in an inclined posture according to claim 1, wherein an angle of inclination of said shaft is adjustable.
Claim 5
Dependent Claim
31 words
The apparatus for rotating reaction vessels in an inclined posture according to claim 1, wherein said driving means is adapted to rotate said reaction vessel holders at 10 to 100 rpm.
Claim 6
Dependent Claim
32 words
The apparatus for rotating reaction vessels in an inclined posture according to claim 4, wherein said second driving means is adapted to rotate said reaction vessel holders at 25 to 55 rpm.
Claim 7
Dependent Claim
34 words
The apparatus for rotating reaction vessels in an inclined posture according to claim 1, 4 or 5, wherein the shaft is inclined at an angle of below 45° with respect to the horizontal plane.
Claim 8
Dependent Claim
32 words
The apparatus for rotating reaction vessels in an inclined posture according to claim 6, wherein the shaft is inclined at an angle of 10° to 20° with respect to the horizontal plane.
Claim 9
Dependent Claim
70 words
The apparatus for rotating reaction vessels in an inclined posture according to claim 1, wherein the reaction vessel holder comprises a first portion for holding a reaction vessel, a second portion for slidably fitting the reaction vessel holder to the first plate, and a third portion which is brought into contact with said second plate, said first and third portion being located on opposite sides of the first plate respectively.
Claim 10
Dependent Claim
30 words
The apparatus for rotating reaction vessels in an inclined posture according to claim 1 or 8, further comprising an adjuster for controlling the rotation speed of the reaction vessel holders.
Claim 11
Dependent Claim
27 words
The apparatus for rotating reaction vessels in an inclined posture according to claim 9, further comprising an adjuster for controlling the rotation speed of the first plate.
Claim 12
Independent Claim
238 words
An apparatus for rotating reaction vessels in an inclined posture comprising: a first plate; a shaft for rotatably supporting said first plate, said shaft being rotated by a first electric motor via a reduction gear at a predetermined speed; a plurality of holes provided on an edge portion of the first plate in an equally spaced relationship; a plurality of reaction vessel holders fitted into the holes, said reaction vessel holders having a first portion located over the first plate so as to hold a reaction vessel, a fitting portion adapted to fit the reaction vessel holder through the hole, and a contact portion is located under the first plate; a second plate which is rotatably supported by the shaft, one side face of which is provided with a first gear which is adapted to engage with a corresponding second gear provided on the side face of the contact portion of each reaction vessel holder; a third gear secured to the rear face of the second plate, said second plate being rotated by means of a second motor via a reduction gear, a fourth gear engaging with the third gear and the reduction gear, and the third gear for rotating the reaction vessel holders via the second plate at a predetermined speed; and a base fixing the shaft in such a manner that the reaction vessel holders may be inclined at a predetermined angle to a horizontal plane.
Claim 13
Independent Claim
238 words
An apparatus for rotating reaction vessels in an inclined posture comprising: a first plate; a shaft for rotatably supporting said first plate, said shaft being rotated by a first electric motor via a reduction gear at a predetermined speed; a plurality of holes provided on an edge portion of the first plate in an equally spaced relationship; a plurality of reaction vessel holders fitted into the holes, said reaction vessel holders having a first portion located over the first plate so as to hold a reaction vessel, a fitting portion adapted to fit the reaction vessel holder through the hole, and a contact portion is located under the first plate; a second plate which is rotatably supported by the shaft, one side face of which is provided with a first gear which is adapted to engage with a corresponding second gear provided on the side face of the contact portion of each reaction vessel holder; a third gear secured to the rear face of the second plate, said second plate being rotated by means of a second motor via a reduction gear, a fourth gear engaging with the third gear and the reduction gear, and the third gear for rotating the reaction vessel holders via the second plate at a predetermined speed; and a base fixing the shaft in such a manner that the reaction vessel holders may be inclined at a predetermined angle to a horizontal plane.
