  • Method of making iron-base articles having a remelted layer
    Patent number: 4772340
    Abstract: An iron-base article such as a camshaft has a remelted layer of high wear resistance on a cam surface, for example. To make such an iron-base article, molten metal is poured into a mold with a chill set therein to cast an iron-base article having a chilled region formed in contact with said chill. Then, metal powder which provides wear resistance upon being mixed is added to at least a portion of said chilled region. A high level of energy is applied to the portion of the chilled region to heat and remelt the same, and the remelted portion is thereafter cooled to form a remelted layer therein.

  • Method of and apparatus for remelting and hardening a shaft
    Patent number: 4761192
    Abstract: A method of and an apparatus for remelting and hardening an elongate workpiece such as a shaft having a plurality of axially spaced shaft portions to be processed. The shaft is held in a second position, heated, and thereafter transferred to a first position close and parallel to the second position. The shaft is then held in the first position, and the outer surface of one of the shaft portions is remelted and hardened with a torch. Thereafter, the torch is moved parallel to the shaft to remelt and harden the adjacent shaft portions successively.

  • Method of and apparatus for supplying powdery material
    Patent number: 4627990
    Abstract: A method of and an apparatus for supplying a powdery material to a workpiece to be processed thereby. According to the method, the powdery material is discharged from a hopper and metered, and then fed into a tube extending in the vicinity of the workpiece. Ultrasonic vibrations are imparted to the tube to supply the powdery material to a portion to be processed of the workpiece while the amount of the supplied powdery material is being detected. The apparatus includes a hopper for storing the powdery material, the hopper having an outlet, a tube extending from the outlet to a position adjacent to the workpiece for conveying the powdery material therethrough, and an ultrasonic vibrating device mounted on the tube for imparting ultrasonic vibrations to the tube, and a device mounted on the tube for detecting the amount of the powdery material supplied through the tube.
