45869189, May 6, 1986

Filed:

Oct 1, 1984

Appl. No.:

6/656646

Inventors:

Paul M. Cole - Wilmington DE

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

B04B 502

US Classification:

494 20

Abstract:

A centrifuge rotor is characterized by the provision of a force transmitting arrangement operably associated with a sample container or a sample container support housing assembly for transmitting centrifugal force imposed on the sample container to a stress confining enclosure at locations other than the location at which the enclosure is directly loaded.

Filed:

Mar 29, 1978

Appl. No.:

5/891400

Inventors:

Paul M. Cole - Wilmington DE

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

D04H 304

US Classification:

28100

Abstract:

A restrained web of orthogonal strands is formed by first traversing the strands according to the disclosure of U. S. Pat. No. 4,016,631 in a diagonal pattern with V-shaped reversals between two rows of strand-restraining elements along the selvedge of the web and then converting the diagonal pattern to an orthogonal pattern by forming an extended loop in each strand along the selvedge.

Appl. No.:

6/656644

Inventors:

Paul M. Cole - Wilmington DE

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

B04B 502

US Classification:

494 20

Abstract:

A sample container for a swinging bucket centrifuge rotor is characterized by a planar pivot surface that is adapted to engage in a supported relationship with each of a pair of knife-like pivot edges. The edges engage the surface along an interrupted line contact that intersects the axis of the container.

Appl. No.:

6/668420

Inventors:

Paul M. Cole - Wilmington DE

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

B04B 502

US Classification:

494 20

Abstract:

A centrifuge rotor is provided in which an array of loops is circumferentially provided about the exterior of the hub. The loops have openings therein which receive a hook-like appurtenance mounted on a sample container and support the same for pivotal rotation from first to second position. The loops are resiliently mounted to the hub such that increased centrifugal force is accommodated by radially outward deflection of loops. The loops may be torsioned to untwist as the carrier pivots from the first to the second position.

International Classification:

D04H 304
D04H 305

US Classification:

28101

Abstract:

A method of traversing a strand between two spaced rows of strand-restraining elements moving together in the same direction in the same plane to form a web is implemented by a pair of strand-engaging members associated with each row of strand-restraining elements for slideably engaging the strand and moving it in alternate traverses toward one and then the other row while forming a loop in the strand during each traverse. The loop is brought into a plane parallel to the plane of the rows of strand-restraining elements and beyond the rows. Means are provided for disengaging the loop from the strand-engaging members and depositing the loop around the strand-restraining elements.

International Classification:

B04B 502

US Classification:

494 20

Abstract:

A centrifuge rotor which a central hub is characterized by a flexible carrier formed from a plurality of fibers arranged in a predetermined textile structure. The carrier has a socket formed at the radially outer end thereof by the interconnection of the fibers. The socket may receive a vessel therein.

Inventors:

Paul M. Cole - Wilmington DE

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

B04B 502

US Classification:

494 20

Abstract:

A top loading swinging bucket centrifuge rotor is characterized by the provision of a sample container knife edge pivot element which engages the sample container along a substantially line contact as the container pivots from an initial to a second position. The container may be inserted into the rotor such that any diametrical dimension thereof is aligned with the line contact, thus avoiding the necessity of orienting the container with respect to the rotor. A guide slot for guiding the motion of the container is disposed radially inwardly of the pivot elements.

International Classification:

B65H 1732

US Classification:

226 97

Abstract:

A hydrojet for propelling textile yarn at high speeds to a collector includes a source of high pressure water issuing from an orifice to form a jet stream, which is aligned to contact yarn passing through a slotted engager guide located directly above a tube through which the yarn is propelled by the jet stream. The angle of the jet stream with respect to the axis of the tube is about 6. degree.
