This disclosure relates to a plasma generation device particularly adapted to an electrothermal-chemical propulsion system. The device comprises a membranous conductive substance having structural compositions which enable the formation of a continuous and volumetrically distributed, segmentally varied plasma arc. The membranous substance is versatile and operates, inter alia, as a fuse wire, plasma incubator, plasma container, plasma distributor, plasma infusion and permeation media as well as a fuel container.

Annular plasma injector

A wellhead seal assembly for sealing between first and second pipe members comprises an annular elastomeric body having, in cross-section, a generally rectangular shape comprising a first flat radial surface, a second flat radial surface, an inner circumferential surface and an outer circumferential surface; said inner circumferential surface comprises a generally convex portion that extends from an imaginary plane connecting the inner circumferential edge of each of said first radial surface and said second radial surface; said seal assembly further comprises at least one annular, non-metallic spring member in said elastomeric body positioned generally tangentially to the intersection of either of said radial surfaces with said inner circumferential surface.
