Device for sealing electromagnetic waves
First Claim
1. A resilient electromagnetic shielding device comprising:
- a plurality of conductive wire coils canted along a centerline thereof;
means for preloading said plurality of coils in a manner causing coil spacing along the circumference of adjoining coils to be less along a seal-load portion thereof than along other coil portions on the circumference of adjoining coils, said coil spacing along the seal-load portion being selected to limit the passage of electromagnetic energy with a wavelength greater than a selected value.

Abstract
A resilient electromagnetic shielding gasket utilizes a plurality of conductive wire coils which are loaded in a manner so that coil spacing may be selectively adjusted at specific areas along the circumference thereof in order to provide an electromagnetic shield. Other portions along the circumference of the gasket provide sufficient biasing capability to take up for variations that may occur due to torquing, eccentricities, irregularities and other variables and thereby imminent contact between mating surfaces under load. The spacing along a seal-load portion of the gasket is selected to limit the passage of electromagnetic energy with a wavelength greater than a selected value.

36. A resilient electromagnetic shielding device comprising:
-
a plurality of conductive coil means, interconnected and canted along a centerline thereof, for causing the gasket to exert a generally constant force over a selected range of deflection of the gasket in response to loading thereof; means, orienting said plurality of coil means at a turn angle for controlling the magnitude of the generally constant force within the selected range of deflection and for causing coil spacing along the circumference of adjoining coils to be less along a seal-load portion thereof than along other coil portions on the circumference of adjoining coils, said coil spacing along the seal-load portion being selected to limit the passage of electromagnetic energy with a wavelength greater than a selected value, said turn angle being greater than zero degrees and less than 90 degrees. - View Dependent Claims (37, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 56)
