Abstract: A water impervious cable construction for aerial, underground, or underwater use which includes at least one central electrical conductor, an overlayer of insulation material such as a plastic, a shield layer formed of a plurality of individual conductors (or the equivalent) which may be spirally wrapped and which shield layer is embedded in a layer of semiconducting material (which may also be a plastic), a layer of overlapped moisture barrier metal foil material, and a further overlayer of insulating material. The cable is manufactured on a substantially conventional cable extrusion line in which the partially manufactured cable (insulated core or cores wrapped with the shield conductors) is introduced into an extruder and a layer of semiconducting material is extruded thereon, wrapped with metal foil tape (which may include an edge located sealant), and introduced into a subsequent extruder to form one or more outer coatings.

Abstract: A method and apparatus for automatically adjusting soluble oil flow rates to control physical properties of continuously rolled rod including a nozzle for spraying the rod with fluid, a tank for providing the fluid to the nozzle, a valve means in series with the tank for regulating the fluid flow to the nozzle, a controller means connected to and for controlling the valve to ensure that the fluid flow reaches a desired predetermined rate, a computer means connected to and providing said controller with the desired predetermined fluid flow rate, a flowmeter in series with the valve means for measuring the actual fluid flow rate to the nozzle and providing this information to the controller means so that, if necessary, the valve means may be adjusted to achieve the desired predetermined fluid flow rate and an historical data generating means for automatically adjusting said desired predetermined fluid flow rate in accordance with actual measurements of at least one physical property of the rod whose value depen
