Use a ribbon filament fed into a cylindrical heater; the increased surface area improves both traction and heat transfer. The original patents cover a spring-loaded shutoff valve that might not work nearly as well as described when immersed in viscous goo. IIRC, there's a crosswise plunger shutoff, too. Rather than retracting the filament with the feed motor, lift the feed assembly with a solenoid by a specified amount to depressurize the nozzle. I should have taken better notes; it got overwhelming after a while.
