  • Patent number: 4565914
    Abstract: A method and apparatus for demounting a metal plate spot welded to a metal member. In accordance with the method, a hollow electrode rod is placed in opposition to the periphery of a spot weld between the metal plate and the metal member, an electric arc is formed between the electrode rod and the metal plate, the periphery of the spot weld is melted with arc heat, and the resultant molten metal is drawn up through the hollow portion of the electrode rod. The method may be performed with an apparatus having a hollow internal rod which includes an electrode rod retaining portion at a forward tip end thereof. A rod retaining mechanism retains the internal rod for free longitudinal movement in opposite forward and rearward directions, elastically urged in the forward direction. A sliding block is movable in the forward and rearward directions, urged forward by an elastic member. Structure is provided to prevent movement of the sliding block forward of a predetermined forward position.

  • Patent number: 3940592
    Abstract: A pad comprising at least one sheet of material having a thermoplastic resinous composition and a heater actuable to heat and soften the sheet, the pad being for use in alignment of machine equipment, rails, beams, girders, or other constructional elements relative to a horizontal base, vertical or inclined line, or to other constructional elements. In use the pad is placed between the equipment, rail or the like and a support or abutment therefor, and the heater is actuated so as to soften the pad just sufficiently that the weight of object or a force thereon reduces the thickness of the pad an amount equal to the desired movement of the object necessary to achieve the desired alignment.

  • Patent number: 3936661
    Abstract: An electrothermally deformable levelling pad utilizable in padding, levelling or aligning girders, rails or any other constructional or structural elements. The levelling pad comprises at least one thermoplastic plate member and an electric heater for heating the thermoplastic plate member to soften or melt to cause the overall thickness of the pad to reduce to a value sufficient to bring an article or machine to a predetermined level. The plate member is made of a thermoplastic random-copolymerized polyester which comprises an acid component and a glycol component.
