Patent ID: 7255556

Claim:
Apparatus for delivering heat from a heat-producing operation to a heat-consuming operation separated horizontally one from another, comprising: a powder; means for heating said powder in said heat-producing operation; a duct for conveying heated powder from said heat-producing operation to said heat-consuming operation and means for introducing said heated powder into said duct; means for cooling said powder in said heat-consuming operation; a duct for conveying cooled powder from said heat-consuming operation to said heat-producing operation and means for introducing said cooled powder into said duct; means for vibrating said two ducts, the vibration including a vertical component at a vibrational intensity sufficient to place said heated or cooled powder in a liquid-like state, the pressure of said powder falling in said two ducts; and means for raising the pressure of said powder to compensate for said fall in pressure in said two ducts.
