Abstract
Two sets of heater support members angularly distributed around a central vertical member are radially extendable individually or in groups to position heater elements within a preset distance of the cylindrical walls of any one of a series of pressure vessels having a range of diameters. A convex bottom heater support member is provided for each diameter vessel and is axially telescoped into the central vertical member so that an additional set of heater support members can be installed between the first mentioned two sets of heater support members and the bottom heater support member to accommodate for varying depths of the vessels in the series. Thermocouples are extended from the annealing device by actuators which use a spring or pneumatic pressure to press the thermocouple against the vessel wall with a preset constant force for accurate temperature measurements. The actuators use pneumatic pressure to retract the thermocouples to preclude damage during withdrawal of the annealing device from the vessel.
