Abstract: A saw chip collector for use in cutting slots in a work, comprises an enclosure surrounding the saw blade except for an opening at the cutting position, a floating block mounted on the enclosure at the blade cutting position and spring biased against the work for sealing the top of the enclosure against the bottom of the work, an opening in the enclosure at the hub of the saw blade for drawing air into the enclosure, and an output port in the enclosure for flushing out the sawn chips.

Abstract: A process and apparatus for direct extrusion of thermal barrier profiles is disclosed. The process comprises the steps of providing an elongated structural member having a lineal cavity therein with an open portion, driving the elongated member past a filling die while simultaneously guiding the elongated member so as to positively locate the open portion of the lineal cavity with respect to the filling die in order to completely close the cavity at the location of the filling die, continuously extruding thermoplastic along the cavity through a fluid flow passage in the filling die, and removing a lineal portion of the structural member opposite to the open portion of the lineal cavity to form the thermal barrier profile.
