Abstract: A detachable seal assembly for a pressurized constant process oven through which a flat filament is passed and which seals the oven against the environment surrounding the oven including a resilient aperture formed by opposed flaps which extend from a transverse portion in the direction of movement of the filament to sandwich the filament. Compression is provided to the seal assembly such that the friction of filament movement tends to stretch the flaps to seal the resilient aperture about the filament. The seal assembly includes a clamp to enable ready replacement to minimize process down time during replacement.

Abstract: Apparatus and method for forming long lengths of laminated superconducting tape by passing three foils over idler pulleys, through a solder bath and between pinch rollers having a portion which extend above the solder bath to enable cleaning of the pinch rollers during the formation of the superconducting tape with means to adjust the pressure applied by the pinch rollers, and to adjust the laminated tape takeup tension independently from the foil process tension.
