Abstract: A stirling engine which uses a dual pressure shell surrounding the high pressure and temperature engine components. Space between the shells is filled with an incompressible and insulating liquid material, such as a liquid salt. The liquid may have a filler material to prevent excessive movement. The liquid provides a time varying pressure field, driven by the pressure variations in the Stirling engine working fluid, which cancels the pressure differential on heat transfer tubing. The heat transfer tubing is inside of a dome which contains an incompressible, highly thermally conductive liquid, such as Sodium. The combination described allows a Stirling engine to operate at significantly higher temperatures and pressures relative to existing technology.

Abstract: A pass-by insulating glass window unit for replacing single glazing including a sealing assembly sandwiched by glazings having dissimilar plane surface dimensions. One glazing, the exterior glazing, has the plane dimensions of the single glazing it replaces. The other, the interior glazing, and the sealing assembly have plane dimensions slightly smaller than the dimensions of the window opening. The pass-by insulating glass window unit is assembled with each of the four edges of the exterior glazing extending equidistantly outwardly from the aligned edges of the sealing assembly and the interior glazing. The thickness of the sealing assembly is predetermined to provide an enclosed insulating space of optimum insulating value. For use in double hung window sashes, the thickness is chosen to assure passage of the movable window openings, and to position the interior glazing to be in approximate alignment with the plane of the interior surface of the wood sash.
