Abstract: The present invention incorporates a conductor contact apparatus, a conductor defect detector, and a relay or equivalent added to the emergency stop circuit of a conductor insulation extruder apparatus in order to detect conductor defects and shut-down the extrusion apparatus before the conductor defect can cause the extruder to become blocked, interrupting normal production operations. The defect detector is especially adapted to detect variations in the cross-sectional area (or apparent cross-sectional area) of a conductor being insulated.

Abstract: A modular drum rack for storing and stacking drums. Two, three, four, or more laterally adjacent modules may be assembled together in a unit, to accommodate an equal number of drums in a single tier. Subsequent tiers can be stacked upon one another to form a drum stacking rack. The modules include openings for receiving fork truck tines to allow the units to be moved by a fork truck. Openings are provided on four sides of the units to permit handling from all directions. Two sets of openings are provided on the front and back of the unit to provide a balanced lift point for the unit with either an even number of drums or an odd number of drums. When the units are empty they are adapted to be interlocked with one another to reduce space requirements for return shipment.

Abstract: A lift attachment for a lift truck or other vehicle or support having a vertically adjustable lift bar. The lift attachment includes a housing with upright side walls which bear against the lift bar, a top flange and a bottom mount block which receives and supports one end of a forwardly extending lift rod for supporting coiled goods. The top flange has an upper catch bar extending downwardly and rearwardly for suspension from the top edge of the lift bar of the truck. A pair of catch plates are adjustably mounted upon the lower end of the side walls and include up-turned rearwardly extending lower catches to retainingly engage the bottom edge of the lift bar.

Abstract: The manual lifter and mover assembly or dolly includes a base and a vertically movable carriage mounted on the base. The base is provided with a pair of wheels and includes a pair of parallel channel members of equal length forming tracks which face the carriage. The carriage has a pair of outer vertical elements and an intermediate vertical element. A lift plate or fork-like element is carried by the lower end of the carriage for engaging and supporting the load. A pair of roller assemblies are carried by each of the outer vertical elements, with the roller assemblies extending into the opposite tracks of the channel members. A manually operated nut and screw jack assembly is interposed between the base and the carriage, with the jack assembly having a pair of telescopically arranged inner and outer tubes. The lower end of the inner tube is secured to the base while the outer tube is secured to the intermediate vertical element of the carriage.
