    摘要: A method of continuously forming a composite structure comprised of a three-dimensional fabric including first and second sheets of fabric which face each other and which are connected by intermediate yarn, the method including providing a continuous supply of three-dimensional fabric; impregnating the three-dimensional fabric with resin which is thermoreactive; mating the three-dimensional fabric with a first outer strip which contacts the first sheet of fabric, and a second outer strip which contacts the second sheet of fabric to form a stratified structure containing the impregnated three-dimensional fabric; feeding the stratified structure along a path in a feed direction X which is straight; heating the stratified structure to at least partially polymerize the resin between the first outer strip and the first sheet of fabric and between the second outer strip and the second sheet of fabric, while the resin impregnating the intermediate yarn of the three-dimensional fabric remains substantially in the plastic state, so that the first and second outer strips adhere respectively to the first and second sheets of fabric; parting the first and second outer strips as the stratified structure is fed in feed direction X to at least partially distend the intermediate yarn of the three-dimensional fabric; and fully solidifying the resin impregnating the three-dimensional fabric.

    摘要: Foraminous plates formed from coiled or parallel tape lengths may be inserted between the tubesheet and a ported casing-end in a hollow-fiber type permeator, to convey effluent from the fiber lumens to the port and to support the tubesheet against the pressure differential between its inner and outer faces. The face of the support plate which the tubesheet will bear against is defined by edges of the tapes, which are held radially or laterally apart by spacing means adapted to permit effluent flow through the plate between the tapes. Either the casing-end or the plate surface bearing against it is grooved.

    摘要: A shaped article is formed of thermoplastic sheeting which consists of a pair of sheets of thermoplastic material spaced apart and interconnected by longitudinally extending ribs. The combination of the sheets and the ribs form elongated passageways in the sheeting. Individual sections of the sheeting have the ends of the passageways sealed closed so that a gaseous medium, such as air, is trapped in the passageways. The sheeting is formed in an extrusion process with one of the sheets having a greater thickness than the other. The individual sections of the sheeting are formed into a shaped article with the sealed character of the passageways being maintained so that the sheets remain in spaced relation in the shaped sections. The difference in thickness between the sheets is selected so that, following the shaping operation, both sheets have substantially the same thickness.
