Application No. 10/320,073
spindle area beyond said lower end of said heat regulating
element through said upper spindle area beyond said upper
end of said heat regulating element.
23. A method for regulating heat generated by a rotary
spindle assembly comprising inputting a temperature signal
generated by a temperature sensor and controlling at least
one fluid source as a function of said temperature signal,
wherein said rotary spindle assembly comprises:
a rotary drive motor;
a rotary spindle coupled to said rotary drive
motor;
a heat regulating element arranged about said
rotary spindle and comprising a regulating element frame
defining a fluid inlet and a fluid outlet and a fluid
conduit extending from said fluid inlet to said fluid
outlet, wherein said fluid source is coupled to said fluid
conduit, said fluid conduit defines a substantially
cylindrical heat regulation void, said heat regulation void
defines an inside diameter selected to accommodate an
outside diameter of said rotary spindle and a
circumferential gas flow path between said rotary spindle
and said fluid conduit, said heat regulating element defines
an open framework arranged about said rotary spindle such
that upper and lower ends of said heat regulating element
are open to said substantially cylindrical heat regulation
void from said lower spindle area to said upper spindle
area; and dimensions of said cylindrical heat regulation
void defined by said heat regulating element are established
so as to permit flow of exhaust gases from said lower
spindle area beyond said lower end of said heat regulating
element through said upper spindle area beyond said upper
end of said heat regulating element; and
