Abstract: A kit for adapting tungsten-inert-gas welding torches of conventional design to use high amperage current. This comprises an internally and externally screw-threaded tube of highly conductive heat-resistant material which is designed to screw onto a cable housing terminal on the torch body, an insulating gasket which seats against an external shoulder of the torch body, and an insulating sleeve which fits over the internally and externally screw-threaded tube in place on the cable housing terminal, and seats against the gasket. This combination provides gripping means for the operator of the welding torch while dissipating the heat generated by the high operating current.

Abstract: This discloses a system for lifting or conveying granular, pulverized or fluid material from a first location to a second location. A long flexible tube, open at the ends, encloses a highly flexible rotary driven helical coil spring equipped at parallel, spaced-apart positions along its length with a plurality of attachments, called "portable flights", which may comprise a shallow cylindrical cup formed from a pair of semicircular plates. The cups are secured to a succession of rungs in angularly staggered relation along the length of the helical spring, and serve to pick up and convey a substantial quantity of the pulverized, granular or fluid material from an input container, in which the tube is immersed, to a product chute near the top of the tube leading into a collection hopper.

Abstract: Welding torch comprises a combination collet body which functions interchangeably for electric arc welding, of the open arc type using a consumable electrode, or for inert gas shielded welding using a non-consumable electrode. The collet body has a screw-threaded collar at one end which is screwed into the welding head. At the other end, it has a slitted or splined chuck. The slightly enlarged central body portion between the collar and the chuck includes a plurality of gas vents. For open arc welding, a consumable electrode, interposed into the chuck, is secured in place by a constricting metal adapter sleeve which also serves to close the gas vents. For inert gas shielded welding, the consumable electrode and the metal adapter are replaced by a nonconsumable electrode and a ceramic shield open at one end. The open vents permit inert gas to escape under the ceramic shield and surround the nonconsumable electrode during the welding process.
