HIGH POROSITY PARTICULATE BEDS STRUCTURALLY STABILIZED BY EPOXY
The present invention provides a porous thermal regenerator apparatus and method of making a porous thermal regenerator comprised of metallic or intermetallic particles that are held together in a porous three dimensional network by a binding agent (such as epoxy). One aspect of the apparatus is that the porosity of the porous thermal regenerator is greater than the tapped porosity of the particles comprising the porous thermal regenerator; moreover, the high-porosity apparatus is durable, that is, it remains intact when exposed to strong time- varying magnetic forces while immersed in aqueous fluid. This high porosity, when combined with high strength and aqueous heat transfer fluid stability, leads to improved porous thermal regenerators and concomitantly to magnetic refrigerators with improved performance.

The first mode transfers heat from the CHEX to the HHEX. In the second mode of operation, the periodic switching of the valves is suspended to allow unidirectional flow of the HTF through the HHEX, the beds, and the CHEX such that heat is transferred from the HHEX to the CHEX.

A method of testing the integrity of microprogramming within a computer processor employs a test calculation designed to exercise instructions and to reveal errors in those instructions. The problem of testing instructions using the very instructions which may possibly be corrupt is addressed by developing a signature passed from instruction to instruction providing a low likelihood of a false positive outcome. A time-out system is used in the evaluation of the test calculation to capture a wide variety of other pathological operating conditions.
