Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
152 words
Blending apparatus, comprising: a. a stationary member having a first surface b. a rotary member having a second surface opposed to said first surface; c. a first plurality of vanes extending from said first surface toward said second surface; d. second and third pluralities of vanes extending from said second surface toward said first surface, said second and third pluralities of vanes being positioned on said second surface so that said first plurality of vanes interleave between said second and third pluralities of vanes during rotation of said rotary member; e. at least some of said vanes being inclined to provide a pumping action in a direction toward said second set of vanes when said rotary member is rotating; f. means for supplying a viscous fluid to said third plurality of vanes; g. means for withdrawing said fluid from said second plurality of vanes; h. and means for rotating said rotary member.
Claim 2
Dependent Claim
152 words
Blending apparatus, comprising: a. a stationary member having a first surface b. a rotary member having a second surface opposed to said first surface; c. a first plurality of vanes extending from said first surface toward said second surface; d. second and third pluralities of vanes extending from said second surface toward said first surface, said second and third pluralities of vanes being positioned on said second surface so that said first plurality of vanes interleave between said second and third pluralities of vanes during rotation of said rotary member; e. at least some of said vanes being inclined to provide a pumping action in a direction toward said second set of vanes when said rotary member is rotating; f. means for supplying a viscous fluid to said third plurality of vanes; g. means for withdrawing said fluid from said second plurality of vanes; h. and means for rotating said rotary member.
Claim 3
Dependent Claim
21 words
The apparatus defined in claim 1, wherein at least some of said vanes are inclined to provide a centripetal pumping action.
Claim 4
Dependent Claim
44 words
The apparatus defined in claim 1, wherein said second surface is on one side of said rotary member, and further comprising means, on the side of said rotating member, opposite said first surface, for pumping said viscous fluid to said third plurality of vanes.
