Abstract: A liquid dispensing system and methods including color-coded visual indicia to assist an operator in the proper selection of the components and in the configuration of those components in the system during setup, maintenance and diagnostics. Color-coded indicia is also provided to assist an operator in the proper selection of a solenoid for use in a particular application. Various components of the liquid dispensing system, such as the melter unit, controller, hoses, electrical cordsets and solenoid, include visually identifiable color-coded indicia on the surfaces of the components, such as color-coded rings, bands and characters, to assist the operator in the component selection and configuration processes.

Abstract: A method and apparatus for coating telephone cable or other continuous lengths of cylindrical objects with a continuous coating of molten thermoplastic sealant material. The cable or cylindrical object is passed through an annular array of nozzles operative to apply multiple beads of molten thermoplastic material to the surface of the cable or object. A liquid impervious casing is then placed over the bead coated cable while the beads are still in a molten state. The casing compresses the beads and forms them into a continuous coating of thermoplastic material surrounding the cable or object and contained within the liquid impervious casing.
