Abstract
Abstract A fluid distribution manifold for the division of a segmented fluid stream into a plurality of similarly configured segmented fluid streams is provided and comprises a manifold body forming a manifold chamber, a fluid stream inlet, and a plurality of fluid stream distribution outlets to flow the similarly configured fluid streams from the distribution chamber. The volume of said manifold chamber is no greater, and preferably substantially less, than the volume of the smallest of said fluid stream segments to thus insure substantial manifold chamber washout to prevent contamination of a succeeding fluid stream segment by the residue of a preceding fluid stream segment, and provide for accurate division of said segmented fluid stream into said plurality of similarly configured segmented fluid streams.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
157 words
A fluid distribution manifold for dividing a first fluid stream which comprises successive fluid segments of a plurality of different fluids including a cleansing fluid, the smallest segment having a volume at least as great as a predetermined volume, into a plurality of similarly segmented streams comprising, means forming a fluid distribution chamber, fluid inlet means to flow said first fluid stream to said fluid distribution chamber, said fluid inlet means comprising a fluid inlet probe in the form of a needle which is arranged generally axially of said fluid distribution chamber, fluid outlet means including a plurality of fluid distribution outlets in the form of radially disposed arms to flow said similarly configured fluid streams from said distribution chamber, said fluid distribution chamber having a volume which is not greater than said predetermined volume, whereby said fluid distribution chamber will be substantially filled by each of said fluid segments to insure substantial washout of said chamber.
Claim 2
Dependent Claim
157 words
A fluid distribution manifold for dividing a first fluid stream which comprises successive fluid segments of a plurality of different fluids including a cleansing fluid, the smallest segment having a volume at least as great as a predetermined volume, into a plurality of similarly segmented streams comprising, means forming a fluid distribution chamber, fluid inlet means to flow said first fluid stream to said fluid distribution chamber, said fluid inlet means comprising a fluid inlet probe in the form of a needle which is arranged generally axially of said fluid distribution chamber, fluid outlet means including a plurality of fluid distribution outlets in the form of radially disposed arms to flow said similarly configured fluid streams from said distribution chamber, said fluid distribution chamber having a volume which is not greater than said predetermined volume, whereby said fluid distribution chamber will be substantially filled by each of said fluid segments to insure substantial washout of said chamber.
Claim 3
Dependent Claim
19 words
