Abstract
Abstract A system for distributing fibers pneumatically from a source to any of a plurality of distributors and electrical control circuitry for determining which distributors receive fibers in which order. Several electrical control circuits for sequentially checking each of the distributors in a system to determine which of them is demanding fibers and to sequentially satisfy the demands for fibers by opening valves associated with the distributors so that the air stream containing the fibers is drawn into a distributor, wherein the air stream and the fibers are separated, are disclosed. Also disclosed are a number of different distributors suitable for removing fibers from air streams.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
120 words
A method of distributing fibers from at least a single source to a plurality of stations, comprising the steps of: checking, only after one of said stations indicates a demand for fibers, each of said stations in a fixed sequence to determine which of said stations is demanding fibers, halting said checking whenever a given station is determined to be demanding fibers, and entraining said fibers from said source in an air stream connecting said source to a given station, removing said fibers from said air stream at said station determined to be demanding fibers until said station is no longer demanding said fibers, and continuing said checking until each of said stations in said fixed sequence has been checked.
Claim 2
Independent Claim
120 words
A method of distributing fibers from at least a single source to a plurality of stations, comprising the steps of: checking, only after one of said stations indicates a demand for fibers, each of said stations in a fixed sequence to determine which of said stations is demanding fibers, halting said checking whenever a given station is determined to be demanding fibers, and entraining said fibers from said source in an air stream connecting said source to a given station, removing said fibers from said air stream at said station determined to be demanding fibers until said station is no longer demanding said fibers, and continuing said checking until each of said stations in said fixed sequence has been checked.
Claim 3
Dependent Claim
26 words
A method as in claim 1, including the step of preventing the removal of fibers from said air stream at stations which are not demanding fiber.
Claim 4
Dependent Claim
35 words
A method as in claim 1, wherein said air stream is constrained in a pneumatic tube and including the step of purging said tube after all of said stations in said sequence have Been checked.
Claim 5
Dependent Claim
30 words
A method as in claim 1, including the step of delaying said entraining for a given time after said checking of all of said stations in said sequence is completed.
