Abstract: Devices, systems and methods to prevent damage to power and communication conductors located in cold occurring regions, with an elongated cylindrical tubular assembly of closed cell foam within a braided/woven layer that can be sealed to provide longitudinal strength and a snag resistant durable and flexible outer coating. The assembly along with communication and power lines is pulled through new power and communication ducts and conduits and in retrofitting existing power and communication ducts, so that the assembly reduces the volume spacing in the ducts/conduits that can be damaged by water intrusion which expands during freeze conditions.

Abstract: Provided is a method for manufacturing a fishing net formed from a plastic net that can be handled by winding or folding although the net has plastic rigidity. The fishing net is manufactured by (1) a step of preparing a multifilament yarn formed by bundling a plurality of core-sheath type composite filaments, in each of which a core component is made of polyethylene terephthalate and a sheath component is made of polyolefin, (2) a step of preparing a yarn thread obtained by paralleling a plurality of the multifilament yarns, (3) a step of twisting or braiding four yarn threads 11, 12, 13, 14 to obtain a net constructed with strands 1 and intersections 2, (4) a step of heat-treating the net under without pressure to melt the sheath component of the yarn threads 11, 12, 13, 14 constituting the strands 1 and the intersections 2, followed by solidifying, thus obtaining a plastic net, and (5) a step of forming the fishing net using the plastic net.

Abstract: An animal, bird, and repellent formulation and method for warding off deer, geese, birds and insects from shrubs, grass, water, walks, parking lots in around buildings and the like. The formulation is a mixture of water, rosemary oil, mint oil, cedar oil, kaolin clay, a thickener, preservative, white distilled vinegar and dried eggs. This formulation can be applied to a support medium, such as crushed eggshells, nutshells, or corncobs and then disbursed over the surface to be protected. The mixture can also be formed into a viscous composition and sprayed over the area. Additionally, this mixture can be applied to stagnate water to kill mosquito larvae or on a variety of surfaces to repel insects such as flies, spiders, beetles, ants and so forth.

Abstract: Aquaculture net (30) having a bottom net (31) and side walls (32), said bottom net (31) configured of four or more mesh parts (34) of a chain link fence, said chain link fence comprising a wire direction (33) and a flexible direction, wherein the wire direction of each mesh part (34) is perpendicular to the outer side (36) of said mesh part, said outer side corresponding to the circumference of said bottom net, and wherein the outer sides of said mesh parts are knotted. The invention also provides a method for manufacturing such an aquaculture net.

Abstract: Elevator rope arrangement in which the elevator car and counterweight, travelling along guide rails in an elevator shaft, are supported by suspension ropes, which are attached to the top part of the elevator car and passed via at least one diverting pulley to the counterweight. Separate hoisting ropes are attached to the lower part of the elevator car and passed to lower part of the counterweight via at least one diverting pulley. The hoisting rope is a substantially thin rope made of synthetic fiber and having a sheath made of plastic material.

Abstract: An antimicrobial, cut-resistant composite yarn which has a core member including at least one cut-resistant strand, a cover member including at least one strand wrapped around and enclosing the core member, wherein at least one strand in either the core member or the cover member is treated with and incorporates an antimicrobial compound. The yarn can be used to fabricate cut-resistant garments, such as gloves, worn by meat cutters and others who work with knives, saws and other sharp implements. The antimicrobial effect reduces bacteria, mold and fungi growth on the garments between washings.

Abstract: A rope including a heat sensitive component which is subject to a visible change in appearance, such as a color change, when exposed to a selected elevated temperature resulting from a strain-related heat release from the rope. The heat sensitive coating may be contained in a coating over a fiber of the rope or a rope strand, or may be incorporated in sheath located over the load-bearing core of the rope.

Abstract: A cut-resistant tarpaulin has a waterproof coating bonded to a cut-resistant woven fabric. The fabric has a leno or gauze weave. The fabric has warp yarns and weft yarns of braided fibers. The fibers have an initial modulus greater than 400 grams per denier.

Abstract: An asbestos-free rope packing comprising at least 3 strands of a twisted, ceramic fiber-containing paper wherein:(a) each of said strands contains at least one carrier insert;(b) said twisted ceramic fiber-containing paper contains about 3-9 wt. % of a suitable bonding agent;(c) said paper has a thickness of about 0.0015 to 0.045 inches; and(d) said paper has a width of about 0.50 to 4.0 inches.Also, a process for forming the rope packing from twisted strands of a ceramic fiber-containing paper is provided.

Abstract: In making synthetic rope or cable, a plurality of filaments are brought in parallelism into a core and compacted by a plurality of ribbons or tapes wound about the core under tension in opposite directions to form a uniform jacket that is torsionally stable. An outer sheath which may be urethane or other plastic material is applied to the jacket under sufficient pressure to penetrate the jacket but not the core, and then the urethane is cured. The rope or cable of the invention has a core of substantially parallel filaments free to move within the jacket of ribbons wound about the core and penetrated with the urethane or other plastic material. The method affords many advantages in speed of manufacture and cost, and provides a rope or cable of greater tensile strength and flexibility than other rope or cable constructions.

Abstract: A cable structure having a stranded inner conductor and an insulating layer over the conductor is formed by feeding a tape of semiconducting material onto the wire as it enters an extruder head. The tape is not spirally wound on the conductor but rather is fed longitudinally along with the wire into the extruder head so as to dispose the tape about the wire and beneath the insulation layer extruded thereon. The product formed has a good concentricity and the tape element conforms generally to the stranded wire to provide a minimum thickness of the tape composition to permit the cable to function effectively at medium voltage. The tape employed is preferably a semiconducting tape which can serve to distribute the electrical stresses emanating from the conductor when it is at high voltage. The tape may be formed of a crosslinkable material and the outer insulation may also be crosslinkable.

Abstract: An improved synthetic twine and method of manufacturing same are disclosed. The synthetic twine comprises at least one longitudinally extending oriented synthetic ribbon which has been fibrillated to provide a net-like structure having fine fibril stems connected by finer fibril branches, and a synthetic binder in thin band form made of a material compatible with the synthetic ribbon. The synthetic binder is spirally wrapped around and fused to the synthetic ribbon. The method of making a twine comprises the steps of providing at least one longitudinally extending ribbon, orienting the synthetic ribbon and fibrillating the synthetic ribbon to provide a net-like structure having fine fibril stems connected by finer fibril branches. Thereafter, a synthetic binder in thin bank form is spirally wrapped and fused around the synthetic ribbon which has been oriented and fibrillated.
