Abstract
A continuous, noncyclic magnetic refrigerator consisting of a liquid nitrogen cryostat having a motor-driven wheel with a pressed, porous rare earth compound as a rim that rotates through two thermally separated inner reservoirs of liquid helium, the first reservoir being at an elevated temperature relative to the second reservoir, two superconducting magnets of different field strengths, the larger of which is situate in the first reservoir and is adjacent to the said rim while the smaller magnet is positioned in the second reservoir adjacent to said rim, and said reservoir or reservoirs having a convection-driver pump to increase circulation of the helium in said second or first and second reservoirs through said porous rim.
