International Classification:

F16B 3922

US Classification:

411301, 411903, 1984801-4811

Abstract:

A method and apparatus for applying coatings to a portion of the internal bore or threads of a fastener or similar article having an opening on at least one end is provided. A 360Â coating with material is provided using centrifugal force to assist in direction the material to a desired surface, which does not require use of a pressurized air stream in order to propell the coating material toward the walls of the article desired to be coated.

Appl. No.:

11/588201

Inventors:

Gerald Snow - Almont MI, US
Charles Stempien - Wolverine Lake MI, US

International Classification:

A47J 36/02

US Classification:

228101000

Abstract:

A coated welding tip and nozzle assembly is disclosed. The tip and the nozzle are coated with a coating composition comprising titanium dioxide. The coating provides resistance to adhesion and accumulation of weld spatter on the nozzle and tip and facilitates weld spatter removal. The coating also protects against thermal damage of the nozzle by providing a thermal barrier.

Appl. No.:

12/124832

Inventors:

Gerald F. SNOW - Almont MI, US
Charles M. Stempien - Wolverine Lake MI, US

International Classification:

F16B 41/00
F16B 19/08

US Classification:

411258, 411361, 470 28, 427284

Abstract:

A fastening device such as a rivet collar that includes a retention element is disclosed. The retention element enhances the retention of a fastener within the fastening device by frictionally engaging the fastener. The retention element comprises a heat resistant base polymer, such as a reactive hot melt, an ethylene acrylic acid copolymer, or a polyethylene polymer blend, that does not melt or become tacky even at high temperatures, and therefore has high stability even under extreme storage conditions. Also disclosed is a method of forming such retention element on a fastening device.

Assignee:

ND Industries, Inc. - Troy MI

International Classification:

B05D 312
B05D 500
B05D 5324
B01H 302

US Classification:

118676

Abstract:

A method and apparatus for the application for one or more deposits of material to a succession of discrete articles such as fasteners as is provided. The method and apparatus of the present invention deposits a droplet or extended bead of thermoplastic or thermoset material onto the surface of a part that is urged into a postion once it solidifies to extends above the surface of the part to create assembly resistance when the part is assembled into or over another part.

Assignee:

ND Industries, Inc. - Troy MI

International Classification:

B05D 102
B05D 722

US Classification:

427 8

Abstract:

An apparatus for providing a barrier coating on a portion of discrete objects such as fasteners utilizing a liquid coating material is provided. The present invention introduces either a plurality of loose or interconnected parts onto a magnetized conveyor system and optically senses when parts are present. When parts are sensed, the sensor triggers a discrete shot of liquid coating material such as a fluorocarbon to be deposited onto a predetermined portion of each part. These parts can then be transferred to a second magnetized conveyor system that supports an opposite surface of the parts than the first conveyor. The invention can also remove excess coating material and also be provided with dryers or heaters to fix the coating material to the parts if necessary.
