Thermo-magnetic machine with movable temp.-dependent magnetic body - uses two temp-changing mediums to move body under local influence system of magnet system

摘要

The thermo-magnetic machine has a movable enclosed body whose magnetic properties are temp. dependent and a magnet system which the body can locally magnetically influence. There is a first medium that the body can thermo-magnetically influence by bringing the temp. of the body to below or near to that of a thermo-magnetic transition. A second medium can bring the body to a hiqher or lower temp. As a result of the thermal influence of the first medium, and the local influence of the magnet system, the body moves. The thermo-magnetic influencing media act directly on the body and comprise gas and/or liq. and/or solid. The part of the body brought to temp. by the first medium is in proportion to the remaining part which is brought to a higher or lower temp. by the second medium is the inverse of the relationship between the thermal transmission properties of medium to body and vice versa of first and that of the second medium.
