Harry A. Webb 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).

  • Continuous compressive preshrinking and drying method
    Patent number: 4446606
    Abstract: After compressive shrinking, moist (15% to 25% moisture by weight of fabric), preshrunk fabric is directed into a drum-type drier in which it is restrained while being dried to a moisture content of say 5% to 14%. Thereafter, the fabric is completely dried in a loop-type drier and additionally preshrunk while the fabric is in a relaxed state.
    Type: Grant
    Filed: October 15, 1980
    Date of Patent: May 8, 1984
    Assignee: Cluett, Peabody & Co., Inc.
    Inventors: Jackson Lawrence, Harry A. Webb, John R. Frederick
  • Method of improved pile appearance in liquid ammonia treated fabric; pretreatment with crease resistant resin
    Patent number: 4425131
    Abstract: The method of pretreating pile fabrics with resin at relatively low percentage levels in order to stabilize the appearance (pile shrinkage and distortion) of the pile as affected by a subsequent treatment with liquid ammonia.

  • Process and apparatus for removal of ammonia in a liquid ammonia fabric treating system
    Patent number: 4189847
    Abstract: A process and apparatus are disclosed for removing ammonia from fabric which has been previously treated with liquid ammonia, by subjecting the fabric to a solution of water saturated with ammonia maintained at a temperature level high enough to vaporize ammonia in the fabric without requiring commercially uneconomical input of heat energy. Subsequent steps remove the remainder of the ammonia and water trapped in the fabric, the system providing essentially complete recovery of all ammonia at substantially reduced heat energy expenditure.
