Abstract: A method of manufacture of large high pressure composite bottles. In accordance with the method, polar caps are placed on the ends of a reusable mandrel, which is then coated with an appropriate mold release and then coated or at least covered with a material which will become the internal protective coating for the finished bottle, and then coated with an impervious liner material. Thereafter, a few layers of windings of high strength resin impregnated filament are put on the mandrel and the resin is cured to make the internal protective coating and liner self-supporting. The resulting thin shell is then cut circumferentially near the middle thereof and the two halves are removed from the mandrel, then rebonded together so that the thin shell may act as a self-supporting mandrel over which the structural shell of the bottle is subsequently wound. This allows the original mandrel to be used over and over again as desired. Various details and variations of the method are disclosed.

Abstract: Motion picture sound film is spliced by cutting the film transversely between the adjacent picture frames, then longitudinally forward between the picture frames and sound stripe to the end point at which the sound relates to the first picture frame adjacent the transverse cut, and then transversely across the sound stripe at said end point. A similar cutting is made at the opposite end of a length of the film to be removed, whereby to provide a pair of mating ends on film portions to be joined. These mating ends are arranged with their mating edges in abutment, the forwardly extended sound stripe of the first cutting fitting into the notch formed by the removal of sound stripe in the second cutting, and the picture frames adjacent the transverse cut being in edge-to-edge abutment. Pressure sensitive transparent tape then is applied across the abutting transverse and longitudinal edges to secure the splice.

Abstract: Sheet material is moved along its length from a supply to a take-up spool and the material is inspected as it is moved. A garment pattern image is projected on and is moved with the material. The operator determines where the material is to be cut either from the length accumulated on the take-up spool or from the image projected on the material, and if a flaw in the material is detected, the operator determines if the flaw should be removed by identifying the pattern part in the garment from the image projected on the material where the flaw will appear. If the flaw is to be removed, the operator cuts the flaw out and splices the cut ends of material together at splice marks in the image projected on the material. The spools loaded with sheet material with this procedure are loaded in a creel, and the ends of the sheets of material from the spools in the creel are aligned in a vertically stacked arrangement and moved to a cutting apparatus where the garment pattern is cut in the stacked sheets of material.
