Abstract: An installation for storing and recovering heat energy having a principal application in solar power stations.The heat produced is stored in a storage reservoir when the converted energy demanded is less than the heat energy produced, and recovered in the opposite case, these operations being carried out entirely automatically. The heat transfers are effected through a thermofluid able to flow by streaming over containers of any shape, enclosing a heat storage substance, and disposed loosely or methodically in said storage reservoir.

Abstract: A heliostat comprises a tubular chassis having a triangular base mounted to pivot about a substantially vertical axis and provided with an oblique support mounted at a point of the triangular base in order to pivot about a horizontal axis. A reflecting panel is pivoted on the base and is slidably attached to an oblique bar in order to fix the panel to the base and orientate the latter as regards altitude. Wheels are provided on the base to unable the chassis to travel on a circular track for orientation as regards azimuth. An application for the heliostat is the recovery of solar energy.
