Adjustable induction coil for heating semiconductor rods

Claim 1

An induction heating coil for use in heating a semiconductor rod comprising: an induction coil adapted to encircle said rod and including a current conducting loop forming an outer section of said coil and a plurality of separable inner sections, whereby at least some of said inner sections may be independently separated from association with said rod; said loop formed of a plurality of convolutions of an elongated tube; said inner sections being removably connected with an innermost convolution of said loop, said inner sections being in substantially continuous electrical contact with said innermost convolution of said loop, said inner sections having a radially innermost surface defining a circle for surrounding said rod, said inner sections being separable from each other along a separating line; an insulating space separating one end of said innermost convolution from the other end of said innermost convolution; conduit means within said inner sections for supporting a fluid flow therethrough; and means for connecting the interior of the tube of said innermost convolution with said conduit means.
