Abstract: DPP:dl Al 6/24/80 23538 OXYGEN REDUCTION SYSTEM AND CONDENSER APPARATUS WITH AUTOMATIC DEFROST                            Abstract A closed loop oxygen reduced gas recirculation system for an industrial dryer includes high volume primary and low volume secondary gas recirculation paths with a condenser apparatus in the secondary path for removing water and solvent.  A natural gas burner produces both oxygen reduced gas for the system and the required energy for the dryer.  An optional condenser apparatus removes water vapor from the oxygen reduced gas output of the burner prior to its reaching the dryer.  The condenser apparatus may include a first heat exchanger and a pair of parallel alternately operating downstream output heat exchangers, such as refrig-eration coils.  The first heat exchanger condenses most of the water vapor from the dryer gas and vaporized solvent is condensed in one of the output heat exchangers while the other is being defrosted.  Sensors detect frost buildup in the operating output heat exchanger and actuate an automatic defrost control which causes dampers to switch and direct exhaust gas to the previously nonoperating output heat exchanger while the previously operating heat exchanger is defrosted, as by a hot defrost gas.  Also, the heat ex-changers may be of the counterflow type connected such that the cooled exhaust gas is fed back through the heat ex-changers in reverse order to act as the cooling fluid.  A defrost fluid may be delivered to the nonoperating heat exchanger during defrosting.

Abstract: ABSTRACT OF THE DISCLOSURE           A worn conical tubular mold, exhibiting irreparable surface flaws or defects at the inner tubular wall of the mold at the location of the former region of the molten bath level existing in the tubular mold when the same was previously used during continuous casting, is formed or reformed through the use of an explosive forming technique with the aid of a cali-bration arbor or mandril so as to possess a new reversed taper.          As a result, the surface flaw or defect now is located at the region of what becomes the new strand outlet of the reformed tubular mold and unimpaired, fissure-free mold wall material comes to lie at the region of the tubular mold where there will appear the new molten bath level when the reformed tubular mold then is again used for casting purposes.

Throughbolts fit through the slots in the band, holes in the force bars and the holes in the spacing member, so that upon tightening of the bolts the ends of the band clamp are forced outward, thus exerting a compressive stress on the tubular member.
