Abstract
Abstract A heat energy transfer device including tanks, shielding means, and a drive means. The tanks contain fluid that is highly responsive to temperature variations over a practical temperature range in order to provide vapor pressure to move the fluid to operate the drive means. Each tank is connected to the drive means. Shielding means are connected to each tank in order to provide energy source guidance functions by controlling the movement of the piston engines in relation to the energy source.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
A heat energy device for converting energy supplied by a radiant energy source comprising, a tank including radiant energy exposure absorbing surface, a liquid in the tank that partially fills said tank, a gas in the tank that fills the portion of the tank unfilled by said liquid, drive means connected to said liquid in said tank, said drive means being driven by said liquid moved in response to a variation in pressure in said gas do to a variation in the radiation energy being transferred to and from said tank, and means for shielding said radiant energy exposure absorbing surface to provide a variation in the gas pressure in said tank when there is relative angular movement between the radiant energy source and the tanks.
Claim 2
Dependent Claim
126 words
A heat energy device for converting energy supplied by a radiant energy source comprising, a tank including radiant energy exposure absorbing surface, a liquid in the tank that partially fills said tank, a gas in the tank that fills the portion of the tank unfilled by said liquid, drive means connected to said liquid in said tank, said drive means being driven by said liquid moved in response to a variation in pressure in said gas do to a variation in the radiation energy being transferred to and from said tank, and means for shielding said radiant energy exposure absorbing surface to provide a variation in the gas pressure in said tank when there is relative angular movement between the radiant energy source and the tanks.
Claim 3
Dependent Claim
47 words
A heat energy device for converting energy supplied by a radiant energy source as set forth in Claim 1, wherein, said tank is generally flat, and the angular position of said radiant energy absorbing surface in relation to the radiant energy source provides the means for shielding.
Claim 4
Dependent Claim
46 words
A heat energy device for converting energy supplied by a radiant energy source as set forth in claim 1 wherein, a plurality of said tanks fixed in relation to one another, and a plurality of drive means each of which is connected to a single tank.
Claim 5
Dependent Claim
40 words
A heat energy device for converting energy supplied by a radiant energy source as set forth in claim 3 wherein, said drive means are connected to a platform to orient the platform in relation to the moving radiant energy source.
Claim 6
Dependent Claim
44 words
A heat energy transfer device for converting energy supplied by a radiant energy source as set forth in claim 2 wherein, said shielding means include at least one upwardly projecting member to shield at least one surface of the tanks from the energy source.
Claim 7
Dependent Claim
39 words
A heat energy transfer device as set forth in claim 5 wherein, said shielding means includes a platform projecting outwardly from said upward projecting member to shield a portion of the surface of said tanks from the energy source.
Claim 8
Dependent Claim
18 words
A heat energy transfer device as set forth in claim 6 wherein, each said tank is generally L-shaped.
Claim 9
Dependent Claim
32 words
A heat energy transfer device as set forth in claim 7 wherein, said shielding means are generally T-shaped and include a reflective member connected to the lower surface of the cross member.
