    Abstract: AN ELECTROHYDRAULIC CONTAINER FORMING DEVICE WHEREIN A THIN STREAM OF CONDUCTIVE FLUID CONSTITUTES A BRIDGE BETWEEN ONE ELECTRODE AND THE OTHER OF THE SHOCK PRODUCING ELECTRODES. THE CONDUCTIVE LIQUID IS PRESSURIZED TO A HIGHER VALUE THAN THE INTERNAL PRESSURE OF THE CONTAINER. IN OPERATION THE CONDUCTIVE LIQUID IS EMITTED UNDER PRESSURE FROM ONE ELECTRODE BY A TIMING CIRCUIT DRIVING A SHEAR TYPE SOLENOID VALVE. A SECOND TIMING CIRCUIT SYNCHRONIZES THE ELECTRICAL DISCHARGE WITH THE ESTABLISHMENT OF A PREFERENTIALLY CONDUCTIVE BRIDGE ACROSS THE ELECTRODE GAP. A SHARP JET PULSE IS GIVEN OFF FROM THE ARC THUS ESTABLISHED AND THIS DEVELOPS PRESSURE INSIDE THE RUBBER DIAPHRAGM TO PRESS IT AGAINST THE CONTAINER WHICH IS THEN PRESSED INTO THE INTERSTICES OF THE DIE TO GIVE A FULLY STYLIZED CONTAINER.

    Abstract: DISCLOSED HEREIN ARE APPARATUS AND METHOD FOR THE ELECTROPNEUMATIC AND ELECTROHYDRAULIC RE-FORMING AND THE LIKE OF MEMBERS SUCH AS, FOR EXAMPLES, CONTAINER BODIES AND THE LIKE. THE FORCE GENERATED FOR PERFORMING THE RE-FORMING IS CREATED THROUGH THE APPLICATION OF ELECTRICAL ENERGY TO A PAIR OF ELECTRODES POSITIONED WITHIN A CHAMBER TO PROVIDE AN ELECTRICAL DISCHARGE WITHIN SUCH CHAMBER. THE ELECTRICAL DISCHARGE CREATES A PLASMA BUBBLE BETWEEN THE ELECTRODES AND SUCH BUBBLE CONTINUES TO GROW AS CONTINUED POWER IS SUPPLIED TO THE ELECTRODES. ALSO DISCLOSED ARE APPARATUS AND METHOD FOR SEVERING AND FLANGING MEMBERS USING SIMILARLY DEVELOPED FORCE. THE FORCE SO CREATED DRIVES THE WALL OF THE MEMBER OR WORK-

    PIECE AGAINST AN ADJACENT DIE TO PERFORM THE DESIRED OPERATION OR OPERATIONS.

    Abstract: An electrohydraulic container forming device wherein a thin stream of conductive fluid constitutes a bridge between one electrode and the other of the shock producing electrodes. The conductive liquid is pressurized to a higher value than the internal pressure of the container. In operation the conductive liquid is emitted under pressure from one electrode by a timing circuit driving a shear type solenoid valve. A second timing circuit synchronizes the electrical discharge with the establishment of a preferentially conductive bridge across the electrode gap. A sharp jet pulse is given off from the arc thus established and this develops pressure inside the rubber diaphragm to press it against the container which is then pressed into the interstices of the die to give a fully stylized container.

    Abstract: Disclosed herein are apparatus and method for the electropneumatic and electrohydraulic reforming and the like of members such as, for example, container bodies and the like. The force generated for performing the reforming is created through the application of electrical energy to a pair of electrodes positioned within a chamber to provide an electrical discharge within such chamber. The electrical discharge creates a plasma bubble between the electrodes and such bubble continues to grow as continued power is supplied to the electrodes. Also disclosed are apparatus and method for severing and flanging members using similarly developed force. The force so created drives the wall of the member or workpiece against an adjacent die to perform the desired operation or operations.

    Abstract: This disclosure relates to a resistance seam welder for welding lapped sheet material, particularly can bodies, and includes means for effecting inert gas flow between roller electrode surfaces and the interface of the lapped can body edge portions, the flow effecting means being in the form of a manifold into which is introduced inert gas while flexible sealing means are provided for sealingly contacting opposite surfaces of the can body edge portions. In one embodiment of the invention the manifold is formed of two hollow bodies having pairs of walls in sealing contact with at least one pair of the walls being flexible to permit the passage of the lapped edges therethrough as the can body blank is moved along an associated horn. In an alternative embodiment the walls are relatively rigid and each carries flexible seals to permit the passage of can body blanks therethrough. In a final embodiment, the manifold is defined by a plurality of radial ports formed in the roller electrodes with each electrode carrying a pair of annular seals for localizing the inert gas at the seam as it is being welded.
