Abstract: A floating closure seal usable in conjunction with a tapered plug in the conical well of a plug valve body. Forming the seal is an elastomeric composition generally enclosing an arcuate span of a relatively thin, flexible base material. On the backside facing a recess in the supporting plug, the seal includes localized elastomeric projections engaging the recess wall. The projections act to distend the seal on its front side into diametral conformity with the proximate body well surface for effecting a sealing relation therewith.

Abstract: A pipe repair clamp affording wide range of circumferential adjustment to accommodate dimensional variations from nominal pipe size. A flexible band is adapted to partially encircle a pipe section on which it can be drawn tight by means of bolt adjustable lug assemblies secured at each end. The band supports a resilient gasket on its inner face while a spanner element is secured by the band ends to bridge the circumferential gap therebetween. Longitudinally secured to the spanner element centrally intermediate the lugs is a spanner bar serving both as an anchor for one end of the lug adjustment bolts and as a base to resist turning moment of the lugs when the latter are tightened during installation of the clamp onto a pipe.
