Abstract: The invention relates to an apparatus for purifying exhaust gases emitted in CVD processes, especially from installations for the chemical processing of semiconductor substrates for the production of microelectronic components by low-pressure processes, which is characterised by a basic body 1 with an outer wall 2,2' and a concentric inner wall 3,3' having a burner 6 arranged centrally therein and possessing both a combustion-gas feed 7 and an exhaust-gas feed 8, the exhaust gas to be purified being burnt with an oxygen excess in the combustion chamber 4, at the upper end of which there is a spray protection facility 9 which is sprayed from above with a sorption agent 11 from a spray nozzle 10. The sorption agent flowing down discharges not only combustion products from the outer annular space 5, but also solid products from the combustion chamber 4 via the flow-off 14. Special advantages are that both pump-oil residues and toxic constituents from CVD processes can be eliminated simultaneously and effectively, and that the apparatus is of simple and compact construction, is economical to produce and operate and can easily be integrated into existing installations. <IMAGE>

Abstract: A multitool punch holder (12) having a head member (26) coupled to a punch press ram (16) as the press upper turret plate (22) rotates to bring the punch holder (12) into alignment with the ram (16). The punch holder (12) includes a rotary tool carrier (56) carrying a series of punches (80), each able to be selectively rotated into alignment beneath a striker rod (100) slidably mounted in a non rotating body member (30). Stroking of the ram (16) causes an engagement feature (108) to engage the striker rod (100) when the head member (26) telescopes into the body member (30) after axial movement of the holder (12) is arrested by contact with the workpiece (120). The striker rod (100) is then driven to force the coupled individual punch (80) into the workpiece (120). The striker rod (100) is urged to a raised position by an encircling stripper spring (110). A separation spring (42) urges the ram (16) and body member (30) to retracted position with the striker rod (100) out of engagement with the ram engagement feature (108). A detachable striker plate (88) of urethane provides non-marring contact with the workpiece (120).
