1,022,404. Thermal regenerators. BRITISH OXYGEN CO. Ltd. Nov. 30, 1964 [Dec. 5, 1963], No. 48040/63. Heading F4K. Regenerator packing for use at very low temperatures, e.g. below 20‹ K., consists of hollow containers filled with helium or neon gas under pressure. The containers 12 comprise coiled small bore metal capillary tubes closed at each end, the diameter of the coil being just sufficient for it to fit into a regenerator 10, Figs. 1 and 4, (not shown). Fins 13 serve as distance pieces to separate the coils when stacked. The regenerator may also be filled in part with conventional packing in the form of flat coils 15 of corrugated aluminium strip.
