A polyurethane covered golf ball is made by allowing the polyurethane cover stock material to partially cure in an open mold and subsequently molding a golf ball product. The molding is done by first molding a smooth-surfaced golf ball product in a smooth-walled fixed-pin mold and then, in a second molding step, using a compression mold to impart dimples onto the smooth-surfaced golf ball product. Between the two molding steps an intermediate curing step is employed. The initial curing time is an open mold and the intermediate curing time between the two molding steps is minimized through the use of a sufficient amount of catalyst, by keeping the smooth mold at an elevated temperature, or by using the fast-reacting chemical components.

A cabling media which is suitable for data transmission with relatively low crosstalk includes a plurality of metallic conductors-pairs, each pair including two plastic insulated metallic conductors which are twisted together The characterization of the twisting is important and relates to parameters such as twist length as well as core strand length/lay More specifically, particular combinations of twist lengths and core strand length/lay are purposely selected for each insulated pair of the cable in order to achieve performance capabilities that significantly surpass those required under TIA/EIA-568A In one particular embodiment of this invention, a cable comprises as its transmission media, four twisted pair of individually insulated conductors with each of the insulated conductors including a metallic conductor and an insulation cover which encloses the metallic conductor The twisting together of the conductors of each pair is characterized as specifically set out herein and the plurality of transmission media are enclosed in a sheath system which in a most simplistic embodiment may be a single jacket made of a plastic material As a result of the particular twist scheme employed for the conductor pairs, operational performance of the resulting cable is improved Also, the cable of this invention is relatively easy to connect and is relatively easy to manufacture and install

Local area network cabling arrangement

An ignition cable which applies ignition current from a power source to a spark plug of a spark ignited internal combustion engine while attenuating radio frequency currents. An inner elongated electrically conductive metallic core made of a high permeability material has an electrically semiconductive layer disposed thereabout and in intimate contact therewith. Insulation surrounds the semiconductive layer. Direct current is effectively and preferentially conducted by the inner core to provide ignition current, while high frequency currents are crowded by the skin effect into the semiconductive layer, where they are damped by the resistance thereof.

This electrostatic shielding tape is a metal strip of low resistance and low reactance folded longitudinally over the length of an insulated power cable having a semi-conducting insulation shield surrounding its insulation. The longitudinally folded metallic tape has its edges free to permit expansion of the insulation and insulation shield, located directly under it, without significant deformation of the insulation and the insulation shield. When the tape is of a metal requiring a thin corrosion-protective coating, the coating on the side adjacent to the insulation shield is preferably semi-conducting to accept charging current from the insulation shield. It is a feature that the metal of the electrostatic shield is in electrical communication with the insulation shield. .Iadd.

A composite fuel and vapor tube having increased heat resistance with a composite wall having a relatively thin nylon liner, a metal strip about the liner and having a longitudinal seam, the tube being encased within a polyethylene jacket. The line thus formed has increased resistance to heat, abrasion and various fuels, is bendable and is capable of maintaining its shape after bending or forming operations.

This filling compound for communication cables has a thixotropic promoting material added to petroleum to increase the temperature to which the filling compound can be heated before it will flow and drip from the cable. Colloidal silica in percentages of 6%, and substantially less than 6% raises the drip point of petrolatum to an unexpected degree, as high as 80 DEG C; and at the same time leaves the filler material soft enough to permit installation of the cables at temperatures as low as -30 DEG C.
