A sight glass assembly (10), especially adapted for use with continuous vulcanizing lines and the like wherein visual or optical access is required, constructed so as to provide self-sealing action during assembly and continuously self-cleaning action during use. A chamber (19) having an exit flow aperture (25) adjacent the viewing element (14) is subjected to a pressurized fluid or gas flow, which is discharged across the inner face of the viewing element. The pressurized fluid or gas is supplied externally through a passageway communicating (16) with the chamber.

Self-sealing, self-cleaning sight glass

Apparatus and method for detecting and locating insulation faults in lengths of electrical conductive cable and plexing those lengths of cable into multiplex cable in one operation, wherein the multiplex cable includes either a bare cable and a plurality of insulated cables stranded together or a plurality of insulated cables stranded together.

Cable plexer fault locator

This disclosure relates to a method and apparatus for manufacturing zinc coated steel tubing from zinc coated steel strip. The zinc lost by volatilization during welding of the seam is replaced in a two-stage metallizing process. In the first stage an aluminum alloy is spray atomized onto the tubing. The alloy contains from 0.45 to 0.95 weight percent iron, no more than 0.10 weight percent silicon, and the remainder aluminum with associated trace elements. Thereafter, in the second stage, zinc is spray atomized over the aluminum alloy-coated substrate.

Galvanized tube welded seam repair metallizing process

Metallic tubing is manufactured from galvanized steel strip by forming the strip into tubular shape, welding the edges together and replacing the zinc lost in welding by atomization metallizing the weld zone first with an aluminum alloy containing from more than about 0.30 to about 0.95 weight percent iron and then with zinc.

This disclosure relates to a system for the continuous high speed production of non-metallic (NM) sheath cable from bare and insulated single strand conductors continuously produced in a high-speed tandem wire drawing and insulation operation. An automated material handling system is provided for transporting and conveying wire pack containers from coiling strands where the bare and insulated single strand wires are coiled into the containers to a station where the wires are continuously paid-out overhead from the wire pack containers and brought together in a jacketing line where PVC coating compound is extruded thereon. A sheathed cable is then coiled and packaged in a continuous manner. The depleted wire pack containers are then transported back to the coiling stands to close the material handling loop. The system is controlled by a programmable computer which controls the delivery of wire pack containers to various ones of a plurality of conveyor lines on a demand basis.

Method and apparatus for continuous production of NM cable

A method of and apparatus for automatically coiling predetermined lengths of multi-conductor electrical cable and packaging individually wound coils of cable are disclosed. A plurality of monitoring devices are arranged along the cable feed path to a coiling machine for continuously monitoring a number of selected parameters of the cable for defects and for generating fault signal outputs indicative of a predetermined variation from a standard value of the selected parameters. Successively wound coils are transferred from the coiling machine to a packaging machine where they are individually packaged, sealed and discharged. The fault signal outputs generated by the monitoring devices are transmitted to the packaging machine to automatically and positively identify a package containing a defective coil by disabling the package sealing mechanism. An electrical circuit is provided for discriminating between faults occurring in a coil being wound and faults occurring in a next successive coil to be wound.
