Abstract: A welding wire conveyor device (1) and a method for locking a pivotable roll receiver off the welding wire conveyor device (1). The device includes a drive roll receiver (11) and a pivotable pressure roll receiver (10). The pressure roll receiver (10) is coupled to a pivotable actuation mechanism (20) enabling movement to a pivoted position. The pressure roll receiver (10) may be locked in the pivoted position by a locking device (200).

Abstract: The invention relates to a welding wire conveyor device (1) and to a method for locking a pivotable roll receiver off the welding wire conveyor device (1) which comprises a drive roll receiver (11) and a pivotable pressure roll receiver (10). Said pressure roll receiver (10) can be coupled to a pivotable actuation means (20). Said pressure roll receiver (10) is locked in the pivoted position by means of a locking device (200) when the pivotable actuation means (20) is actuated.

Abstract: An apparatus for electroplating a rotogravure cylinder out of a plating solution is disclosed. The apparatus includes a plating tank adapted to support the cylinder and to contain a plating solution so that the cylinder is at least partially disposed into the plating solution. The apparatus also includes a non-dissolvable anode at least partially disposed within the plating solution. A current source is electrically connected to the non-dissolvable anode and to the cylinder. An ultrasonic system may be provided to introduce wave energy into the plating solution includes at least one transducer element mountable within the tank and a power generator adapted to provide electrical energy to the transducer element. A holding tank having a circulation pump, a mixing system and heating and cooling elements for the plating solution may be provided.

Abstract: The invention relates to a burner head (9) of an electric arc welding or cutting head, with preferably a melting wire electrode, having a contact nozzle (1) and a spring chuck (2) for releasably holding the contact nozzle (1) on the burner head (9). Both of the contact nozzle and the spring chuck (2) have corresponding means to bring about positive locking between the contact nozzle (1) and the spring chuck in the contact nozzle (1) that is supported on the burner head (9).

Abstract: Polypropylene plastic baskets for phosphorized or non-phosphorized copper anode nuggets are suspended, one on each side of a cylinder to be plated, in a bath of plating electrolyte. The tops of the baskets are disposed beneath the surface of the plating solution, the upper portion of the cylinder is above the surface of the electrolyte, lead anode conductor strips extend downwardly along the insides of the rear walls of the baskets, and the front walls of the baskets are perforate.After the cylinder is printed out, it is returned to the plating apparatus and reversely plated to remove the copper. In order to prevent the copper from building up through the perforations in the inner walls of the baskets and to keep reduced-size nuggets from protruding through the basket openings, a porous plastic sheet is disposed over the lower portion of the inner surface of the inner wall of each of the baskets.
