ABSTRACT:
A thermoplastic control complex for releasably securably bonding and debonding distinct elements together is provided. An elongated exothermic electrical conductor having a predetermined resistivity for each lengthwise unit thereof is provided with a thermoplastic resin selectively positioned along the length thereof. The complex is disposable between two distinct elements so that the thermoplastic resin is selectively transformed from a non-sticky substantially solid state to a substantially liquid state in response to a current being flowed through the exothermic conductor, whereby the thermoplastic resin, in the liquid state, effects wetting of the distinct elements for effecting subsequent releasable securable bonding of the elements together.
