Katherine L. Kilman 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).

  • Dust mop with replaceable electrostatically charged dust collector
    Patent number: 6332234
    Abstract: A dust mop features a dust collector layer made of electrostatically charged nonwoven fabric. The electrostatic charge (a) enables the dust collector to be detachably mounted to the mop head by electrostatic cling; and (b) improves the dust collecting ability of the dust collector.
    Type: Grant
    Filed: May 25, 2001
    Date of Patent: December 25, 2001
    Inventors: Barbara G. Graham, Katherine L. Kilman, Robert L. Graham

  • Electrostatic webs for sewing patterns
    Patent number: 6159325
    Abstract: Electrostatically charged nonwoven webs (fabrics) are used in displays, quilting, toys, and pattern making. The electrostatic charge causes the nonwoven webs to cling to cloth or paper without the need of pins or connectors. In pattern making the charged nonwoven web is detachably secured to a mastern pattern permitting the web to be marked and cut to form a specific sized pattern which is used to cut cloth in a selected size.

  • Electrostatic interfacing, underlining, and applique
    Patent number: 6106760
    Abstract: A thermoplastic fabric for use as a support fabric in interfacing, underlining, and applique carries a persistent electrostatic charge that causes the fabrics in contact therewith to cling thereto in a nonslip relationship. This facilitates sewing of the layers together. The preferred support fabric is a nonwoven fabric such as meltblown and spunbonded fabrics.

  • Electrostatic display device
    Patent number: 5665448
    Abstract: A device for detachably adhering a manipulative to a substrate using electrostatic charges is described. The invention comprises a thermoplastic substrate having imparted thereto a substantially persistent electrostatic charge with paper and/or fabric manipulatives removably adhered thereto by electrostatic attraction. The present invention may be useful for creating visual displays such as display boards, design boards for quilting patterns, sewing patterns, and toys such as dolls and educational games or aides using manipulatives in visual displays. The substrate is preferably made of polyolefin nonwoven webs, particularly polypropylene or polyethylene meltblown webs.
