Abstract
Abstract An apparatus for dividing a flowing multicomponent viscous stream into a plurality of sectors, each having the same weight percentage of each component as in the stream, includes a body member having an entrance and a plurality of exits connected by a plurality of passages. The passages, at one end, all intersect with the axis of the entrance at a common point and are equispaced from each other around the entrance axis.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
170 words
An apparatus for dividing a flowing viscous stream into a plurality of identical sectors and recombining some of said sectors into a single stream comprising: a body member having a circular entrance and a plurality of exits connected by a plurality of passages within said body member, there being more passages than exits, said entrance having a longitudinal axis, one end of each passage terminating at a common point on said axis in said entrance, the other end of each passage being connected to an exit, one of said exits being coaxial with said entrance, said passages in said entrance having equal crosssectional areas and being both equispaced angularly from each other around said axis and equiangularly inclined away from said axis in the direction of flow to divide said entrance into identical sectors extending from said axis to the inner periphery of said entrance, there being more than one passage connected to said exit coaxial with said entrance and only one passage connected to each of the other exits.
Claim 2
Independent Claim
170 words
An apparatus for dividing a flowing viscous stream into a plurality of identical sectors and recombining some of said sectors into a single stream comprising: a body member having a circular entrance and a plurality of exits connected by a plurality of passages within said body member, there being more passages than exits, said entrance having a longitudinal axis, one end of each passage terminating at a common point on said axis in said entrance, the other end of each passage being connected to an exit, one of said exits being coaxial with said entrance, said passages in said entrance having equal crosssectional areas and being both equispaced angularly from each other around said axis and equiangularly inclined away from said axis in the direction of flow to divide said entrance into identical sectors extending from said axis to the inner periphery of said entrance, there being more than one passage connected to said exit coaxial with said entrance and only one passage connected to each of the other exits.
Claim 3
Dependent Claim
43 words
The apparatus as defined in claim 1, there being a single entrance, five exits and eight passages, four of said exits diverging from said axis, the remaining exit being coaxial with said entrance, four of said passages being connected to said remaining exit.
