Method For Control Of Yarn Processing Equipment

US Patent:
7349756, Mar 25, 2008
Filed:
Dec 12, 2003
Appl. No.:
10/530932
Inventors:
Gregory James Scott - Hockessin DE, US
Joseph Anthony Perrotto - Landenberg PA, US
Glen Edward Simmonds - Avondale PA, US
Richard Davis Bryson - Elkton MD, US
William Robert Corcoran - Kennett Square PA, US
William Charles Walker - Wilmington DE, US
Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
International Classification:
G06F 19/00
US Classification:
700144, 700142, 19 03, 19 035, 19 039
Abstract:
A method for starting or stopping each of at least two separately controllable roll-sets () used for processing a yarn (Y) in a stretch-break process, each roll-set comrpising at least two rolls, the method is characterized by the step of each roll-set, changing the speed of each roll from an initial condition to a steady state condition in accordance with a predetermined sequence and in coordination with a change in speed of at least one of the other rolls, such that simultaneous complete breakage of a yarn (Y) being processed in a stretch-break process is minimized.

Method For Deleting And Reintroducing Yarns To A Textile Process

US Patent:
5501250, Mar 26, 1996
Filed:
Nov 22, 1994
Appl. No.:
8/345724
Inventors:
Donald W. Edwards - Wilmington DE
Peter Popper - Wilmington DE
David P. Rule - Wilmington DE
William C. Walker - Wilmington DE
Assignee:
E. I. Du Pont de Nemours and Company - Wilmington DE
International Classification:
D03D 4734
US Classification:
139450
Abstract:
Method to delete and reintroduce individual yarns as needed when they are being fed to a textile process by cutting an individual yarn, that is being forwarded to the process, rapidly to prevent producing a disruptive tension change in the process or in other yarns being forwarded to the process to produce an upstream cut end of an individual yarn; holding the upstream cut end of said individual yarn in an elongated condition at a ready position for reintroducing to the process; and reintroducing said yarn at said ready position to the textile process according to the following steps; metering said individual yarn from said source at a controlled rate; passing said cut end of yarn with a first individual yarn forwarding jet for forwarding said cut end from said ready position and maintaining said cut end of yarn in an elongated condition during said metering; directing said elongated, cut end of yarn in a path past an individual yarn cutter; passing for forwarding said elongated cut end of yarn from said cutter and along an individual yarn path, and maintaining said cut end of yarn in an elongated condition during said passing; and converging said elongated, cut end of yarn with a plurality of individual yarn paths for said plurality of yarns for forwarding said yarn to said textile process.

Method Of Making A Helmet

US Patent:
2013028, Oct 31, 2013
Filed:
Jan 13, 2012
Appl. No.:
13/978153
Inventors:
Joseph D. Trentacosta - Wilmington DE, US
William Charles Walker - Wilmington DE, US
Assignee:
E I DU PONT DE NEMOURS AND COMPANY - Wilmington DE
International Classification:
B29C 65/72, A42B 3/00
US Classification:
28167, 702157
Abstract:
This invention relates to a method of making a helmet using a preform subassembly with arms which have an area that matches a perimeter profile of a specified geometric shape. By use of the area matching perform with arms, the thickness of the helmet is more uniform, seams in the preform can be minimized, and the ballistic resistance of the resulting helmet can be increased.

Stretch Break Method And Product

US Patent:
7267871, Sep 11, 2007
Filed:
Jan 5, 2005
Appl. No.:
11/030000
Inventors:
Joseph Anthony Perrotto - Landenberg PA, US
Peter Popper - Wilmington DE, US
Glen Simmonds - Hampstead NC, US
Albert S. Tam - Hockessin DE, US
David Carlton Visser - Wilmington DE, US
William Charles Walker - Wilmington DE, US
Joseph Leonda Jones - New Castle DE, US
Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
International Classification:
D02G 3/00, B32B 19/00
US Classification:
428369, 428359, 428357
Abstract:
A method for stretch breaking fibers to produce a staple yarn and operating a staple fiber spinning machine that enables the production of a plurality of products of lot size smaller than a large denier tow product. The process includes at least two break zones and a consolidation zone downstream from a second break zone to form a staple yarn. The filaments are broken in a second break zone downstream from the first break zone by increasing the speed of the fiber fed into the process.

International Classification:
B32B 7/02, F41H 5/04, F41H 1/02
US Classification:
428221, 156278
Abstract:
An impact resistant composite article has two or more layers of ballistic fabric and ionomer layers disposed between the fabric layers. The ionomer is highly neutralized so that it has essentially no melt flow. A process also for making such a composite article that involves deposition of an aqueous colloid of the ionomer onto the fabric, followed by drying.
