Abstract: Two universal joint shafts for driving a pair of working shafts of a strip-treating stand are arranged one over the other and adapted to be shortened so as to be uncoupled from said working shafts. For a replacement of one or both working shafts, the unversal joint shafts which are uncoupled from the working shafts and are supported by respective seating structures, which are adjustable in height. To enable an automatic coupling of the universal joint shafts to the working shaft and to permit of the use of interchangeable strip-treating stands, which can only be lifted, the seating structures comprise upwardly facing bearing surfaces, which are adapted to support and to clear said universal joint shafts. Said seating structures are mounted in a carrier, which is adjustable in height and carries also means for adjusting said bearing surfaces in height relative to said carrier only by equal distances in opposite directions.

Abstract: Machines and process for making in a continuous operation a prestressed glass reinforced, thermally insulating panel, structurally stiff, and totally impervious, of indefinite length and with a cross-section shaped as an elongated parallelogram.Steps for manufacture include making the surface of the panel out of a tubular envelope of knitted or woven glass fabric, stretched over a special holding frame, to give it the desired parallelogram shape. Fastened by a continuous knitting process to the opposite faces of the glass fabric envelope, other glass fibers are stretched inside the envelope and arranged according to three principal directions, all of them oblique with respect to the panel faces. The glass fabric envelope is then coated with a plastic resin to make it impervious to gas and covered on one face at least with a metal liner. This liner, made of cryogenic alloy, has its edges upturned and folded, so as to be fastened to the glass reinforced plastic envelope.

Abstract: In the production of V-MOS single transistor memory cells a simplification of the previous technology is disclosed wherein a process is utilized without epitaxial processes and with a minimum of doping processes. First the source and the drain zone of a field effect transistor forming a memory cell are produced and only then is a V-shaped recess formed at the site of these zones. In one embodiment, one re-doped zone is constructed as a flat zone and is produced on both sides adjacent to a second re-doped zone extending deeper into the silicon crystal. The V-shaped recess is then etched in such a way that the two zones are completely separated by the V-shaped recess. The silicon surface in the V-shaped recess is provided with a thin SiO.sub.2 layer and with a gate electrode covering it. Advantageously the gate electrodes of neighboring V-MOS cells are united into a line. This occurs with one of the two zones of the transistor, whereas the other zone remains separate.

This forms a longitudinally extending passage defined on two opposite sides by the two insulating bars and on the other two sides by the two profiles. A tool is displaced through this passage so as plastically and permanently to deform the inner flanges outwardly and into intimate tight contact with the bars.

Abstract: A field effect transistor having a gate on the bottom of a groove in a body of semiconductor material with the source and drain being on a surface at opposite sides of the groove is made by first forming a recess in the surface of the semiconductor body. A metal layer is then coated on the surface of the semiconductor body and on the surfaces of the recess. A layer of a photoresist is then coated over the metal layer. The photoresist is then exposed to a beam of light whose rays extend along a path which is at a very small angle with respect to the surface of the semiconductor body to fully expose a narrow portion of the photoresist layer at one edge of the recess. The fully exposed portion of the photoresist layer is removed to expose a narrow area of the metal layer along the edge of the recess. The exposed portion of the metal layer is then removed and a groove is formed in the portion of the surface of the semiconductor material exposed by removing a portion of the material layer.

Abstract: Home building construction is characterized in a combination sidewall and roof extending from the building base to peak over the length of the building. The combination sidewall and roof provides internally of the home a continuous surface on which a sheet of air-vapor barrier extends from building base to top over insulation material positioned between the rafters.

Each support beam has a barrier sheet affixed to its inside surface prior to installation. The air-vapor barrier overlying the insulation is affixed to the air-vapor barrier on the beam at its top and bottom and is so connected to provide an essentially impervious barrier to moisture laden air within the building.
