This document discloses apparatus for applying an insulating jacket to an advancing electrical conductor and includes a tubular enclosure for suspending said jacketed conductor in the presence of a treatment agent. The enclosure includes a stationary chamber and a telescoping tube to allow opening and closing of the upstream end of it. The telescoping tube is pressed axially against a pivotally supported extruder head.

Apparatus for insulating and treating electrical conductors

This invention relates to a device for regulating the water level in apparatus for treating an insulated electrical conductor, which device comprises two or more gates actuated by a control signal for filling and emptying the apparatus, a first control circuit having a broad range of adjustment, a second control circuit having a narrow range of adjustment, and an inverter, each circuit in turn comprising a first transmitter for producing a measuring signal, a second transmitter for transmitting a reference signal, and a comparator for producing a control signal and transmitting same to the inverter, the inverter supplying the control signal from the comparator of the first or of the second circuit to the gates.

Water-level regulating device

This invention relates to a downstream closure device for apparatus used in treating large-diameter insulated electrical conductors, the device comprising a main exit gasket, a movable plug, an auxiliary exit gasket borne by the plug, and means for controlling the movement of the plug.
