Abstract: In a method for increasing the cover of textile fabrics yarns are used, at least part of which exhibit potential fiber-spreading properties, which can be activated by removing from said yarns, processed into a fabric, the adhesive used for the fiber bonding in the yarn by means of a suitable solvent. The selected number of warp and weft threads per unit area is so small that on the one hand an optimal fiber spreading is obtainable, but on the other hand, after activation of the potential fiber-spreading properties, sufficient cohesion of the fibers in the fabric is retained for further processing of the fabric. After obtaining the desired fiber spreading the fiber bonding, partially lost through the activation, is at least partially restored.

Abstract: Apparatus and method for filling and sealing selected holes in a circuit board with epoxy resin or the like. The board is sandwiched in series between sealing sheets of a thermoplastic material and barrier sheets of a glass fiber or the like to form a laminate stack through which the holes are drilled at selected locations. The stack is disassembled and the board is plated to coat the linings of the drilled holes therein with conductive material, followed by reassembly of the stack together with an overlying resin-carrying sheet such as a glass fiber coated and/or impregnated with epoxy resin. The stack and the resin-carrying sheet are subjected to heat and pressure for causing the sealing sheets to adhere to the board and then for melting the epoxy resin and for forcing it to flow into the holes in the circuit board. After the epoxy resin is cured, the various sheets are stripped from the board leaving the epoxy resin within the holes.

Abstract: An adhesive is provided which comprises a thixotropic binder (24) containing metallic particles (23) of discrete size and specific density concentration. When used to bond faying surfaces (13 and 21/10 and 21) this adhesive is capable of conducting electrical currents on the order of 200,000 amps while withstanding structural loads on the order of 5000 psi. It has particular application in a highly volatile environment such as the skin panel (10) of an aircraft component housing an integral fuel tank (12). Lightning strike currents are thereby conducted in a controlled path (P) adjacent the exterior surfaces (S) of the component as defined by the parts (10, 13, 17 and 21) and arcing inside the fuel tank (12) is avoided.

Abstract: This invention relates to filling material composed of crimped fibers joined together at one end with a high density, and having crimps located in mutually deviating phases, while the other ends of the fibers stay free, and a process for manufacturing such filling material. The filling material exhibits superior bulkiness and thermal insulation, since the recovery force or resiliency of the crimps located in mutually deviating phases causes the fibers to spread sufficiently to contain a large quantity of air among themselves.

Abstract: A technique is described for bonding flexible printed circuitry to a rigid base plane by means of a tacky contact adhesive which is subsequently cured by heating into a nontacky condition. The procedure involves pressing the adhesive on the surface of a rigid support member to which it adheres and subsequently applying a flexible sheet thereto and laminating under moderate pressure. The adhesive is then removed from through holes with a solvent and the resultant assembly subjected to heating to cure the adhesive. It has been found that the use of this procedure permits removal of the solvent without detrimental solvent retention and also avoids the collecting of debris at the edge of the adhesive layer during subsequent processing and use.

Each exterior joint ring is first mounted on a tank section above the end, then such end is caused to abut an opposed end, and then the joint ring is dropped onto stop means prior to the above-mentioned bonding-sealing and resin-introduction steps.
