Abstract

606,851. Stoppers. SAVAGE, D. L. Jan. 21, 1946, No. 1988. [Class 125(iii)] [Also in Group XXXVI] The stem 30 of a mushroom valve 31 is spring- loaded to close a circular filling opening 26 in a container of electrolyte or other electrically conducting medium. The opening 26 is surrounded by a concentric wall 27 and a strap 28 which hinged to a clip 29 around the rim of the wall 27 and locked in position over the latter by a releasable catch 28a.
