Patents by Inventor Addison G. Hardee, Jr.

Addison G. Hardee, Jr. has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method of making optical fiber
    Patent number: 5104433
    Abstract: Methods are provided for making an optical fiber transmission medium which includes optical fiber (21) provided with a coating system (31) typically including two layers each of a different coating material. An inner layer (32) of a first coating material is called the primary coating and an outer layer is termed the secondary. In order to achieve desired performance characteristics, performance is related to properties of a coating system. The coating materials have well defined moduli and the second coating material has an elongation which is substantially less than in prior secondary coating materials. Adhesion levels which are optimized rather than maximized are substantially stable with respect to time. Curing of the coating materials may be accomplished simultaneously or in tandem with the application separately of the coating materials.
    Type: Grant
    Filed: May 29, 1990
    Date of Patent: April 14, 1992
    Assignee: AT&T Bell Laboratories
    Inventors: J. Thomas Chapin, Addison G. Hardee, Jr., Lisa M. Larsen-Moss, Charles M. Leshe, Bob J. Overton, John W. Shea, Carl R. Taylor, John M. Turnipseed
