US Patent:

43864260, May 31, 1983

Filed:

Nov 3, 1980

Appl. No.:

6/203151

Inventors:

Charles D. Pugh - Burlington NC

Assignee:

Burlington Industries, Inc. - Greensboro NC

International Classification:

H04J 316

US Classification:

370 85

Abstract:

A telemetry system including a number of series connected modules having clock inputs and outputs and reset inputs and outputs, each module coupling an associated digital data sources to a master station via a common data bus. Circuitry is provided in each module whereby a self perpetuating reset signal from the master station and successive clock pulses from the master station actuate and deactuate the modules in sequence to multiplex data from all of the digital data sources onto the common data bus.

Aug 29, 1979

Appl. No.:

6/071027

Inventors:

Joe F. London - Greensboro NC

Assignee:

Burlington Industries, Inc. - Greensboro NC

International Classification:

D02G 116
D02G 336

US Classification:

57 6

Abstract:

A method and apparatus for producing novelty yarn with an unusual configuration. An effect yarn is fed to a novelty yarn jet, and a core yarn is fed to a different yarn port in the same jet, the core yarn being maintained substantially taut. The combined core and effect novelty yarn is taken up from the jet and periodically (preferably pseudo-randomly) a pronounced variation in linear density is provided in the combined yarn. This linear density variation is accomplished by introducing a first fluid pulse into the jet at a first position to form a loop in the effect yarn, which loop extends substantially coincident with a portion of the core yarn, and then utilizing a second fluid pulse at a spaced position from the first pulse to impart a spiraling and/or rotating action to the loop of effect yarn to wind the effect yarn around the core yarn. Separate valves are associated with the fluid ports in the jet, and a numerical controller may be utilized for controlling the operation of the valves to produce the variations in linear density. The final novelty appearance of yarn and fabric from it is generated by backwinding and/or weaving the yarn from the take-up package.

Inventors:

Charles D. Pugh - Raleigh NC

Assignee:

Burlington Industries, Inc. - Greensboro NC

International Classification:

D03D 5134

US Classification:

1393702

Abstract:

Apparatus and method for uniquely identifying which of a plurality of filling yarns used by a loom in a weaving process has broken and caused an automatic stop of the loom. The apparatus is particularly suited for fabrication by modifying known and commonly used loom stop motion systems.
