    Abstract: A cable for telephone or other communication circuits comprises a number of conductor arrays, specifically pairs or quads of helically intertwined conductors, each conductor having a metal core coated with a thermoplastic sheath in which a multiplicity of short cellulose fibers are embedded; the fibers have an average length of about 1 mm and project generally radially from the sheath over the greater part of their length. The fibers of the twisted wires interpenetrate and form a mat in the intervening spaces which swells in the event of water penetration through a defective envelope, thereby limiting the propagation of moisture along the cable.

    Abstract: A method of applying multi-color flocking to a base structure in a predetermined pattern. The base surface has an adhesive applied thereto over an area corresponding to the predetermined pattern, and the base surface is advanced through a series of flocking stations, each of which includes a supply of flocking of a different color and each of which includes a flocking stencil which is perforated with a different portion of the predetermined pattern. At each station, the particular flocking stencil thereat is interposed in spaced relation between the flocking supply and the base surface, and flocking is caused to pass through the perforations in the flocking stencil by an electrical potential.

    Abstract: Application of a resin to a pool surface to provide a colored finish that is ultraviolet resistant. The resin may be a powder that can be melted at a fairly low temperature and applied to the pool surface. A first later of resin may be applied (thermally sprayed) to an epoxy layer that is applied to the pool surface after the epoxy has become tacky and before it has cured to provide better adhesion and cause the resin and the epoxy to blend into a single layer. An additional layer of resin may be applied after the epoxy and the first layer of resin fully cured. After the second layer of resin has cured an additional layer may be applied to provide designs and/or markings. The designs/markings may be produced with tape and/or stencils and the next layer may be applied to the non-covered areas to provide the desired look.
