Abstract: A protector module (30) for protecting the conductors of a telephone loop cludes a pair of protector assemblies (40-40') which are supported within a common housing (32). A gas tube voltage protection subassembly (42) of each protector assembly is connected electrically to a grounding subassembly (44) for causing current associated with excessive voltage surges to be conducted to ground. A first electrode includes a portion which extends through annular dielectric and metallic members and an opening of an open-ended metallic container (93) to engage a shunting element (62) of a current protection subassembly (41). The superimposed annular members are held in engagement with the first electrode at a substantially constant pressure by axial forces applied by turned-in portions (109--109) of a side wall of the metallic container. The shunting element is supported at one end of the line pin in an initial position by a fusible material.

Abstract: The invention relates to the monitoring of the filling effectiveness during the filling operation of a waterproof or filled telecommunications cable on a manufacturing line, and includes measuring the capacitance change per unit length of an outer pair of insulated conductors in the cable, measuring the capacitance change per unit length of an inner pair of insulated conductors in the cable, determining any deviations in the measured capacitance changes and utilizing such deviations by feedback control to eliminate further deviation, as well as determining the point of deviation along the cable length.
