Abstract
A heat pipe extends into the path of flow of a viscous fluid, e.g., polymer, for transferring heat from or to the flowing fluid and thereby for solidifying and stopping flow of the fluid or, conversely, for melting the solidified matter for resumed flow thereof. Control may simply increase or decrease the fluid viscosity for varying the rate of flow.
