Filed:

Aug 4, 1994

Appl. No.:

8/286382

Inventors:

Hubert J. Booth - Florence SC
Paul H. Steagall - Florence SC
Michael W. Wright - Florence SC

Assignee:

Wellman, Inc. - Johnsonville SC

International Classification:

B07C 5342

US Classification:

209580

Abstract:

Masses of differently optically transmissive materials, such as plastic bottles of different composition or color, are separated using the different transmissivity to separate masses in a moving stream.

Filed:

Jan 8, 1992

Appl. No.:

7/818046

Inventors:

Harry Allen - Lake City SC
Daniel E. McMenamin - Kells, IE
Hubert J. Booth - Florence SC

Assignee:

Wellman, Inc. - Johnsonville SC

International Classification:

B29C 4706
B32B 3130
D01D 534

US Classification:

264171

Abstract:

A method of forming bicomponent fibers in a sheath-core relationship in a spinning pack that incorporates a plurality of adjacent plates that define predetermined flow paths therein for a sheath component and a core component to direct the respective components into the sheath-core relationship. The method comprises maintaining the differential pressure in the spinning pack between the sheath component and the core component low enough to avoid leaks and doglegging, while maintaining the total spinning pack pressure low enough to prevent leaks and doglegging.

International Classification:

B02C 1320
B02C 1900
B02C 2500

US Classification:

241 27

Abstract:

A method of sorting plastic items by measuring the effect an item has on light directed at a stream of items from a light source, then selectively removing items from the stream based on a comparison of the light measured and the light emitted from the detector is provided. The invention also includes an apparatus for separating plastic items which comprises a light source, a detector for measuring the effect an individual item has on light emitted from the detector, and sortation means for selectively removing items from the stream based on a comparison of the light emitted by the light source and that measured at the detector. A method for separating single plastic bottles from engaged interlocked bottle clusters comprising directing an air jet at an item sufficiently forceful to displace a single bottle to a collection means but insufficiently forceful to displace an interlocked bottle cluster is also provided.
