Patent number: 4262321Abstract: An aircraft static discharger and mounting structure therefor is disclosed formed of non-metallic conductive material, such as carbon filled nylon, for mounting an aircraft static discharger onto a graphite and/or boron composite aircraft skin. The discharger includes a mounting structure formed as a sub-base having a lower surface provided with downwardly extending conical projections terminating in points which engage the underlying graphite composite surface and form electrical contact therewith, providing for the mounting of the sub-base to the composite surface by conventional non-conductive epoxy. A surface conductive to lightning currents is provided by bonding powdered aluminum to the outer surfaces of the discharger base and the sub-base which, together form a lightning diverter strip formed on the discharger, transfer lightning currents over the surface of the base and sub-base to the underlying aircraft structure.Type: GrantFiled: September 26, 1979Date of Patent: April 14, 1981Assignee: Dayton-Granger, Inc.Inventor: Jay D.

Patent number: 4249226Abstract: An electrically conductive strap to be secured to a shoe to ground static electricity accumulated on the body of the person wearing the shoe. The strap consists of an electrically conductive backing, a metallic strip that hooks over the upper edge of a shoe to secure one end of the strap, a pressure-sensitive adhesive coated over the backing and an open mesh scrim applied onto the adhesive which, prior to the application of pressure on the strap, has one surface extending above the adhesive to form a tack-free surface to permit ease of handling prior to use and positioning along the sides and across the bottom of the shoe. The strap adheres to the bottom of the shoe upon pressing the shoe against the floor. The scrim prevents the adhesive from adhering to the side of the shoe as no pressure is applied in this area. Additionally, the strap has a series of transverse rows of perforations so that segments of the strap can be removed to permit the strap to fit various sizes of shoes.Type: GrantFiled: February 22, 1979Date of Patent: February 3, 1981Assignee: Minnesota Mining and Manufacturing CompanyInventors: Walter M.
