<p>A method of forming a mantle - support tube subassembly by supporting a fabric sock of organic material impregnated with a metal compound on a fixture that carries a support tube so that the closed end of the sock is a predetermined distance from the end of the support tube with the skirt of the sock overlying the support tube. The fabric sock is then heated to convert the metal compound to a refractory metal oxide and to decompose and remove the organic material from the sock and to shrink the sock until the skirt of the sock is shrink-secured against the outer 20 surface of the support tube to form the mantle - support tube subassembly.</p> |
