Abstract: To limit the exposure of personnel to radioactivity within the channel head of a steam generator of a nuclear-reactor plant a cartridge sleeve-blank loader for automatically sleeving a plurality of tubes without the intervention of personnel is provided. The cartridge loader includes a turret or drum which carries a plurality of sleeve blanks around its periphery. A lifter engages the bottom of each sleeve bank in its turn at a sleeve insertion position of the turret and inserts the sleeve blank into a tube. Successive sleeve blanks are indexed to the insertion position for insertion into tubes. The sleeve blanks are slightly bowed or curved so that when a sleeve blank is inserted as a sleeve into a tube, the sleeve, since the tube is linear, exerts a restoring force on the wall of a tube which holds the sleeve in the tube when the lifter is retracted. In inserting the sleeve blank, the lifter moves at a low speed until the leading end of the sleeve enters a tube. Then the speed of insertion is increased.

Abstract: A structure such as a wall of a high temperature furnace door is lined with fibrous refractory insulation material which has structural fastening devices embedded therein or interleaved between planks thereof. In one embodiment, plank-like pieces of fibrous refractory material are arranged in a stack extending edgewise with respect to the wall, and sheets of expanded metal are positioned between the refractory planks and are anchored to the wall. The interleaved stack of refractory planks and expanded metal sheets are compressed such that the metal sheets become essentially embedded within the refractory material to securely grip large surface areas of the planks to hold the refractory planks in place. In preferred practice, rods extend through slots formed in the wall and connect with the expanded metal sheets to hold the sheets of expanded metal in place after the interleaved stack has been compressed.

Abstract: A method for forming a sealed coupling between two bodies each body presenting an abutment surface. The respective bodies are arranged so that their respective abutment surfaces are axially adjacent one another, defining a space therebetween in which a deformable gasket is disposed. An axial external force is applied to the bodies for compressing the abutment surfaces together against the gasket to form a seal between the bodies. The bodies are immobilized relative to one another while the external force is being applied to the bodies so that sufficient compression will be maintained by the abutment surfaces to preserve the integrity of the seal when the external axial force is withdrawn. The external axial force is then withdrawn, leaving the two bodies coupled together via the seal.
