The present invention provides new polymer induction bonding technology. Induction heating technologies are utilized to weld, forge, bond or set polymer materials. The invention provides controlled-temperature induction heating of polymeric materials by mixing ferromagnetic particles in the polymer to be heated. Temperature control is obtained by selecting ferromagnetic particles with a specific Curie temperature. The ferromagnetic particles will heat up in an induction field, through hysteresis losses, until they reach their Curie temperature. At that point, heat generation through hysteresis loss ceases. This invention is applicable to bonding thermoplastic materials, wherein only the area to be heated has ferromagnetic particles in it; bonding of thermoset composites, which have been processed with a layer of thermoplastic material on one side; curing of thermoset adhesives or composite resins; or consolidating thermoplastic composites.

Temperature-controlled induction heating of polymeric materials

The tape cell battery system comprises an elongated strip of flexible tape divided into segmented sections of anode, cathode and fluid electrolyte. The electrolyte is stored in a separated segment sealed from the segment containing the anode and cathode. The tape is advanced through nip rolls to individually break open each sealed segment containing electrolyte such that the electrolyte is caused to flow into a single adjacent segment containing said anode and cathode such that only one battery cell at a time becomes electrochemically active while the other battery cells remain electrochemically dormant.

Tape cell battery system

The galvanic battery of the present invention supplies the anode and/or cathode from an elongated strip of flexible tape preferably interconnected through a strip of inactive material functioning as a leader for said tape and for separating the tape entering the electrochemically active compartment of the battery housing from spent tape exiting the electrochemically active compartment. The battery is preferably constructed to include a supply reel having a rotatable core upon which said strip of tape is wound in a cylindrical configuration with the inner winding of tape extending from said core and being threaded through said electrochemically active compartment before being connected back into the electrochemically inactive compartment and wound as the outer winding around the core of the supply reel.
