1,078,620. Thermal regenerators. H. BRANDT, and A. KRITZLER [trading as APPARATEBAU ROTHEMUHLE BRANDT & KRITZLER]. Sept. 28, 1965 [Sept. 29, 1964], No. 41184/65. Heading F4K. In a rotary duct type regenerator-in which a peripheral sealing frame (32) is joined to each rotating duct (20) by an expansion member (33) and also by a number of swivel joints (48) for rotating the frame with the duct, and the frame and its sealing strip (36) are held in sealing contact with the regenerator mass by resilient means, the resilient means comprising a plurality of bolts 40 spaced around the periphery of the duct and attached at one end to the frame (32), each bolt having therearound a spring 43 acting between a fixed point on the bolt and a flange 41 on the duct, the bolt being threaded in the frame and rotatable by a tommy-bar 60 to adjust the pressure of the frame on the regenerator mass-the axial movement of bolt 40, during operation of the regenerator, is limited by an adjustable nut 46 co-operating with a slide 57, 54 (also Fig. 7, not shown) inserted in a guide-way 55, 56, the slide having such thickness as to adjust the clearance a between nut 46 and slide 57, 54 to a desired value, e.g. 5A0 mm. The gap between nut 46 and flange 41 is set approximately before starting the regenerator, and when the regenerator has attained stable operating temperatures, the regenerator is stopped for the short time necessary to insert a slide of the correct thickness at each bolt.
