Abstract: Apparatus for electrolytically treating containers comprising a cell assembly having a cell wall surrounding a mandrel and a lid cooperating with the mandrel and cell wall to form a cavity for the reception of a container, conduit means for introducing an electrolyte into said cavity, and the conduit means including selectively operable port means for(a) conducting electrolyte through said cavity such that only the outside surface of the container can be electrolytically treated and(b) for conducting electrolyte through said cavity such that only the inside surface of the container can be electrolytically treated and(c) for conducting electrolyte through said cavity such that both the inside and outside surfaces of the container can be simultaneously electrolytically treated.

Abstract: This disclosure relates to a jet soldering apparatus for applying a jet of solder to a side seam of a can body formed in a bodymaker. The soldering apparatus includes a heated metal block having an elongated cavity which terminates in a discharge orifice. Solder wire is fed into the cavity and is heated therein by means of electrical heaters connected to the block. The cavity has an inlet in the form of a bore which substantially corresponds to the diameter of the solder wire so that the solder wire prevents any back flow of molten solder through the inlet. The cavity is also in the form of a bore generally conforming to the diameter of the solder wire and is of a length to make certain that the solder wire is fully melted before it reaches the discharge orifice. Feed means are provided to intermittently feed the solder wire in accordance with the presentation of a can body to the discharge orifice. The feed means include a reciprocating chuck and a staionary chuck which act in unison.
