The gasket comprises a knitted core of monofilament synthetic polymer yarns, and a circular warp knitted sheath over the monofilament knitted core, with the sheath being sufficiently conductive to provide shielding from electromagnetic interference over a wide range of frequencies. | InventorsApplicationNo. 294737 filed on 08/23/1994US Classes:277/652, Distinct sheath or covering277/920SEAL INCLUDING ELECTROMAGNETIC SHIELDING FEATUREExaminersPrimary: Cummings, Scott W.Attorney, Agent or FirmUS Patent ReferencesRe33256, 2462334, 2674644, 2755079, 2761203, 3206536, 3247312, 3566064, 3578764, 3812316, 3842628, 4037009, Conductive elastomeric elementsIssued on: 07/19/1977 Inventor: Severinsen4065138, Metal mesh strip and embedded fin gasket for shielding against electromagnetic interference Issued on: 12/27/1977 Inventor: Severinsen4123830, Slide fastener stringer Issued on: 11/07/1978 Inventor: Matsuda , et al.4375009, Shielded electrical cable Issued on: 02/22/1983 Inventor: Fearnside , et al.4639545, Recoverable article for screening Issued on: 01/27/1987 Inventor: Pithouse , et al.4652695, Mesh-covered core strip for high frequency RFI/EMI radiation shielding Issued on: 03/24/1987 Inventor: Busby4684762, Shielding fabric Issued on: 08/04/1987 Inventor: Gladfelter4705916, EMI gasket retaining mechanism for electronic equipment Issued on: 11/10/1987 Inventor: Wadhera , et al.4731500, Electrical shielding tape and method of making same Issued on: 03/15/1988 Inventor: Otsuka4781039, Circular knit with warp knit structure and method of making same Issued on: 11/01/1988 Inventor: Ribarev , et al.4785136, Electromagnetic interference shielding cover Issued on: 11/15/1988 Inventor: Mollet , et al.4822060, Woven tubular gasket with continuous integral attachment means Issued on: 04/18/1989 Inventor: Moyer , et al.4838043, Circular warp knit composite cord Issued on: 06/13/1989 Inventor: Jencks4857668, Multi-function gasket Issued on: 08/15/1989 Inventor: Buonanno4863789, Electromagnetic wave shielding laminate Issued on: 09/05/1989 Inventor: Arai4900877, Shielding and sealing gaskets Issued on: 02/13/1990 Inventor: Dubrow, et al.4921751, Conductive fabric and a method for the manufacture of the conductive fabric, and a conductive sheet and film made using the conductive fabric Issued on: 05/01/1990 Inventor: Wakahara, et al.4931326, Reinforced flexible plastic tubing and methods of manufacture Issued on: 06/05/1990 Inventor: Weil4966637, Method for manufacturing an electromagnetic shielding gasket Issued on: 10/30/1990 Inventor: Laborie4977759, Circular warp knitting machine Issued on: 12/18/1990 Inventor: Jencks4986033, Gaskets and gasket-like devices with fasteners Issued on: 01/22/1991 Inventor: Weil5006666, Electromagnetic shielding gasket Issued on: 04/09/1991 Inventor: Laborie5028739, EMI/REI shielding gasket Issued on: 07/02/1991 Inventor: Keyser, et al.5045635, Conductive gasket with flame and abrasion resistant conductive coating Issued on: 09/03/1991 Inventor: Kaplo, et al.5105056, Electromagentic shielding with discontinuous adhesive Issued on: 04/14/1992 Inventor: Hoge, Jr., et al.5142101, Electromagnetic-shielding gasket Issued on: 08/25/1992 Inventor: Matsuzaki, et al.5188813, Metal fabrics Issued on: 02/23/1993 Inventor: Fairey, et al.5202536, EMI shielding seal with partial conductive sheath Issued on: 04/13/1993 Inventor: Buonanno5386345Electromagnetic shielding mesh Issued on: 01/31/1995 Inventor: Matsuzaki, et al.
