A readily mountable metal seal member is made from a profiled metal bar having a cross section approximately in the shape of a keyhole, the thicker portion of which forms the sealing bead of the seal member and the thinner portion serves to mount it in the joint to be sealed. Sections of the thinner portion may be removed over regions to be curved.

Method of making a metal seal for flanged joints and a seal made by said

A pendulum gate valve with a pressure tight housing and inlet and outlet openings arranged on opposite sides of the housing. The drive rod for the pendulum frame is guided throughout its total path by a joint connected to the pendulum frame which can swivel about the shaft of the pendulum frame but can in addition also move independently of the swiveling motion of the pendulum frame. A guide mechanism is provided for the further movement of the joint outside the swiveling range, which forces the joint onto a path that runs substantially parallel to the drive rod. The guide mechanism consists of a thrust rod forming part of the pressing device which urges the gate valve plate against the sealing bearing surface and which is connected to the drive rod. The thrust rod is mounted in a longitudinally movable manner in the pendulum frame and runs parallel to the drive rod in the closed position of the gate valve plate.

A closure fixture has a slide member or valve for radioactive and toxic media, a fixture housing, a housing cover connected to the housing via a first sealing surface and a closure device with a drive mechanism arranged on the housing cover. The housing fixture comprises an additional sealing surface and an assembly cap has an interior configured to receive the housing cover, an enclosure device and is sealingly mountable to the additional sealing surface. The assembly cap comprises at least one manipulating device for transferring the housing cover together with the closure device into the interior of the assembly cap.
