摘要:
The invention provides a composite wrapping and shielding tape for use in cable manufacture. Embodiments of the composite tape comprise a single tape configuration to separate and shield individual pairs of insulated conductors housed within a cable such as a high-speed data communications cable. The single tape configurations of the invention are multifolded and assembled from foil/film laminates to form a plurality of longitudinal channels or grooves to accommodate one or more pairs of insulated conductors and a variety of cable designs. During cable manufacture, one or more pairs of insulated conductors is wrapped within a continuous shield provided by each longitudinal channel or groove, thereby separating and shielding each pair of insulated conductors and, hence, isolating or at least substantially reducing crosstalk between pairs of insulated conductors contained within the cable. The invention also provides methods for making a multifolded composite tape. The invention further provides a communications cable comprising a multifolded composite tape to separate and shield insulated conductors.

The current invention is a dryer lint removal system and device that is easily and safe to use. It has a 4 inch elbow that connects to the dryer and is connected to a 4 duct tee. The duct tee is connected to a draft blocker, a flex hose and then to a blowout nozzle. The other side of the tee is connected to a standard exhaust hose. A blower is inserted into the blowout nozzle creating a strong air flow, along with the dryer airflow, pulls the lint from the dryer and also out of the exhaust duct works.

A flat cable for use with a mass termination connector having a plurality of regularly spaced terminal elements. The flat cable includes a laminated carrier film and a plurality of discrete conductors held in regularly spaced parallel relationship by the carrier film to match the terminal element spacing of the connector. Each conductor has an insulating jacket made of a thermoplastic material. The carrier film includes an attachment layer of thermoplastic insulatioln having a melting temperature similar to that of the jacket material, and a dimensional stabilization layer made of an insulative material having a melting temperature higher than those of the attachment layer and the jacket material and displaying dimensional stability at the melting temperatures of the attachment layer and jacket material. The jackets of the conductor are fused to the attachment layer, and the attachment layer is held by the stabilization layer. The carrier film can be longitudinally discontinuous to form first cable sections where the conductors are held parallel for ease of termination, and second cable sections where the conductors are not held to increase flexibility and reduce weight. The cable can also be formed into a round configuration to provide advantages during routing, and locating indicia can be applied to the outside surface.
