Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
162 words
A continuous type centrifugal separator comprising: rotary means rotating around a predetermined axis; connection means rotatably provided on said rotary means, the rotary axis of said connection means being in parallel with said predetermined axis and being deviated from said predetermined axis in a direction perpendicular to said predetermined axis; centrifugal separation means rotatably provided coaxially with said predetermined axis; supply/discharge means, one end of said supply/discharge means being connected to said centrifugal separation means, said supply/discharge means extending therefrom to a predetermined position of said rotary means and at the predetermined position being rotatably held on said rotary means and the other end extending outside of said separator, passing on said predetermined axis; and rotary driving mechanism means including means for rotating said connection means around said predetermined axis and rotating said connection means on its own axis, and means for rotating said centrifugal separation means at the half speed of said rotary means by the rotations of said connection means.
Claim 2
Dependent Claim
162 words
