Abstract: A laminated pouch includes a layer of woven synthetic fabric, a layer of polyfoam and a layer of liner material, the layers being bonded together under heat and pressure. During the molding process selected areas of the laminate material is compressed under substantial heat and pressure to permanently deform the laminate into areas of substantially less thickness than uncompressed areas, the compressed areas being of substantial stiffness. The laminate is also formed with edges, and corners of substantial stiffness. The pouch is formed of two such laminate layers which are trimmed and fastened together at the edges. The resulting pouch retains its shape well and is not significantly deformed by the weight or pressure of its contents.

Abstract: A tubular pipe wrench for removing and replacing pipes in inaccessible locations includes a generally cylindrical head member having an internal passage large enough to pass the pipe to be worked on and having a cross-sectional configuration like a triangle with greatly rounded corners. A jaw member having teeth is loosely fastened in each of the three corners by bolts which pass through slots in the sidewalls of the head member. Concentric with the head member is a sleeve having ports for receiving the bolts and which maintains the relative spacing of the bolts even though they move radially in the slots. When a pipe is inside of the head member, a slight turning of the head member and sleeve in either direction causes the teeth of the jaw members to make contact with the pipe, moving the jaws into a position where they are wedged between the pipe and the flattened cam surfaces on the inside of the head. Further turning of the sleeve and head will turn the pipe.

Abstract: In a brain irradiating system a large number of Cobalt 60 radiation sources are carried in ports in a heavy primary shield. After the normal ten year useful life of such radiation sources, they are often difficult to remove because due to corrosion, etc, the aluminum source holders become fused in their ports. The apparatus herein includes a hollow collet which grasps the head of the source holder surrounded by and, preferably, splined to a mechanical puller which securely holds the collet around the source holder cap. Liquid nitrogen is caused to flow into the hollow collet and against the cap of the source holder, causing the aluminum source holder to shrink more than the surrounding steel of the primary shield. The source holder and the Cobalt 60 source may then be either pulled out or, if threadedly engaged with the primary shield, turned out of its port.
