Abstract
Abstract An improved distributor having a central inlet for receiving a stream of gas entrained particles to be divided into a plurality of effluent streams and including an open-ended standpipe disposed therein to maintain the central orientation of the incoming stream thereby attaining a pattern of recirculation which induces a steady flow and uniform distribution of the effluent streams.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
193 words
In combination with a pneumatic transport system having at least one distributor and means for passing gas entrained particles therethrough, said distributor including an upright cylindrical vessel, an upright open-ended cylindrical member coaxially disposed within said vessel and defining therein an inner passageway of uniform horizontal cross-sectional area throughout, the upright member and vessel being spaced from one another to form an outer annular passageway therebetween, the vessel having a plurality of uniformly spaced outlets opening to said outer passageway and a circular inlet disposed in coaxial and subjacent spaced relation to said upright member, support means connecting the upright member to the vessel, an inverted frusto-conical filler piece disposed within the vessel and defining therein a sloped bottom extending downwardly from below the vessel outlets to the vessel inlet perimeter, conduit means for conveying the gas entrained particles to the distributor, said conduit means terminating at the circular inlet, and the horizontal cross-sectional area of the inner passageway being greater than the horizontal cross-sectional area of the vessel inlet thereby assuring the passing of substantially all of the gas entrained particles through the inner passageway prior to discharge from said vessel outlets.
Claim 2
Dependent Claim
193 words
In combination with a pneumatic transport system having at least one distributor and means for passing gas entrained particles therethrough, said distributor including an upright cylindrical vessel, an upright open-ended cylindrical member coaxially disposed within said vessel and defining therein an inner passageway of uniform horizontal cross-sectional area throughout, the upright member and vessel being spaced from one another to form an outer annular passageway therebetween, the vessel having a plurality of uniformly spaced outlets opening to said outer passageway and a circular inlet disposed in coaxial and subjacent spaced relation to said upright member, support means connecting the upright member to the vessel, an inverted frusto-conical filler piece disposed within the vessel and defining therein a sloped bottom extending downwardly from below the vessel outlets to the vessel inlet perimeter, conduit means for conveying the gas entrained particles to the distributor, said conduit means terminating at the circular inlet, and the horizontal cross-sectional area of the inner passageway being greater than the horizontal cross-sectional area of the vessel inlet thereby assuring the passing of substantially all of the gas entrained particles through the inner passageway prior to discharge from said vessel outlets.
Claim 3
Dependent Claim
27 words
The combination according to claim 1 including the upright member having a lower end face bevelled in a direction parallel to the sloped bottom within said vessel.
Claim 4
Dependent Claim
178 words
In combination with a pneumatic transport system having at least one distributor and means for passing gas entrained particles therethrough, said distributor including an upright vessel, an upright open-ended member coaxially disposed within the vessel and defining an inner passageway therein, an annular filler piece disposed in surrounding and fixed abutting relation to the upright member and comprising frusto-conical end sections convergent toward the respective ends of the upright member, the end sections being interconnected by a cylindrical transition section, the filler piece and vessel being spaced from one another to form an outer passageway therebetween, the vessel having a plurality of spaced outlets opening to the outer passageway and an inlet disposed in subjacent spaced relation to the upright member, said upright member being formed with an inlet facing the vessel inlet, and the upright member inlet having a horizontal cross-sectional area which is greater than the horizontal cross-sectional area of the vessel inlet thereby assuring the passing of substantially all of the gas entrained particles through the inner passageway prior to discharge from said vessel outlets.
Claim 5
Dependent Claim
178 words
In combination with a pneumatic transport system having at least one distributor and means for passing gas entrained particles therethrough, said distributor including an upright vessel, an upright open-ended member coaxially disposed within the vessel and defining an inner passageway therein, an annular filler piece disposed in surrounding and fixed abutting relation to the upright member and comprising frusto-conical end sections convergent toward the respective ends of the upright member, the end sections being interconnected by a cylindrical transition section, the filler piece and vessel being spaced from one another to form an outer passageway therebetween, the vessel having a plurality of spaced outlets opening to the outer passageway and an inlet disposed in subjacent spaced relation to the upright member, said upright member being formed with an inlet facing the vessel inlet, and the upright member inlet having a horizontal cross-sectional area which is greater than the horizontal cross-sectional area of the vessel inlet thereby assuring the passing of substantially all of the gas entrained particles through the inner passageway prior to discharge from said vessel outlets.
Claim 6
Dependent Claim
21 words
The combination according to claim 3 including a plurality of laterally spaced support members connecting the filler piece to said vessel.
