Abstract: This invention is a novel method for fabricating leak-tight tubular articles which have an interior flow channel whose contour must conform very closely with design specifications but which are composed of metal which tends to warp if welded.The method comprises designing two longitudinal half-sections of the article, the half-sections being contoured internally to cooperatively form the desired flow passageway. Each half-section is designed with a pair of opposed side flanges extending between the end flanges and integral therewith. The half-sections are positioned with their various flanges in confronting relation and with elongated metal gaskets extending between the confronting flanges for the length of the array. The gaskets are a deformable metal which is fusion-weldable to the end flanges. The mating side flanges are joined mechanically to deform the gaskets and provide a longitudinally sealed assembly.

Abstract: A rotatable disc comprising a plurality of generally parallel plates tightly joined together for rotation about a hub. Each plate is provided with a plurality of angularly spaced lands projecting from a face thereof, the lands of each plate interposed in alternating relationship between the lands of the next adjacent plate. In this manner, circumferential displacement of adjacent sectors in any one plate is prevented in the event that a crack develops therein. Each plate is redundantly sized such that, in event of structural failure of one plate, the remaining plates can support a proportionate share of the load of the failed plate. In one embodiment, the plates are prevented from separating laterally through the inclusion of generally radially extending splines which are inserted to interlock cooperating, circumferentially adjacent lands.

Abstract: Very light weight containers are made of synthetic resin reinforced by fiber material, such as glass fibers or carbon fibers, by first manufacturing a hollow dimensionally precise core having the shape of the container and including access openings at each end of the container. The composite material is then applied to the prefabricated core and after the setting of the composite material the core is either completely or partially removed by chemical means, which are pumped through the inside of the container to etch away the core, which is, for example, made of aluminum. A very controlled and precise core removal may be accomplished in this manner.

A woven roving of predetermined size is formed to provide a skin. Additionally a layer of spacer material is formed which includes a plurality of voids. The roving is attached to the spacer material to form a laminate. The laminate is formed to the insidewalls of the preform mold and then the preform mold is filled with a plurality of hollow balls. A thin layer of resin is poured into the preform mold to connect the balls. The composite is removed from the preform mold and placed into the casting mold after spacer material is attached to the exposed end portions of the composite. A syntatic foam resin is added to the casting mold interior so as to fill all spaces between the balls and all voids in the spacer material. The syntatic foam resin is then cured and the mold parts are removed thereby producing a module.

Abstract: A method of continuously processing two bands of material into profiled rails, inserting insulating material adjacent their lateral longitudinal borders, and then connecting their lateral longitudinal borders through the insulating material. Initial corrugations are formed in each of the bands, and the bands are simultaneously passed between rotating pairs of forming rolls. The initial corrugations formed in the bands are increased so that the length of each enveloping line of each part of each band is longer than the enveloping line contemplated for the corresponding part. The longitudinal border of one of the rails is provided with projections, and the border of the other rail is provided with openings. Finally, the longitudinal border provided with projections is bent around the other longitudinal border, and its projections are forced through the strip of insulating material into the openings of the other longitudinal border.

Abstract: A catalytic reactor is made by providing a generally cylindrical catalytic substrate of oval transverse section and clamping the same between paired housing shells to form a housing of oval section spaced from the substrate by means of a pair of wire mesh ropes seated within a corresponding pair of grooves extending around the periphery of the substrate at axially spaced locations. Each rope is compacted from a matrix of multiple layers of resilient stainless steel knitted wire and is interlocked with the housing by means of a pair of inwardly opening channels of the housing spaced axially by an inwardly projecting rib of the housing. The grooves in the substrate are pressed radially into the latter while the same is in a plastic uncured condition, thereby to compact and reinforce the grooves to withstand the localized compressional force of the ropes seated therein after the substrate is cured and hardened and clamped between the housing shells.
