Abstract: The present application provides a primary reflector in a solar collection system. The primary reflector includes a first reflective section that can reflect solar rays onto a first focal line, a second reflective section on the left side of the first reflective section, and a third reflective section on the right side of the first reflective section. The second reflective section can reflect solar rays to the right side of the first focal line. The third reflective section can reflect solar rays to the left side of the first focal line.

Abstract: Procedure for pumping liquid at high temperature through a pipe, characterized in that the liquid at high temperature is pressed, by means of a fluid at low temperature that is inert in relation to the liquid at high temperature, away out of a first reservoir that is mounted on an extremity of the pipe. The liquid at high temperature which is pressed out is taken up in a second reservoir that is mounted on the other extremity of the pipe, while the aforementioned fluid that is in the second reservoir, is let out, after a time the liquid at high temperature is now pressed out of this second reservoir and is taken up again in the first reservoir, and this by means of the aforementioned fluid that is now let out of the first reservoir and is pumped into the second reservoir. The pumping procedure including means to calculate a flow rate through the pipe via temperature and level indicators, taking into account expansion or contraction of the high temperature liquid.

Abstract: Mirror, in particular for the utilization of solar rays, which comprises a core (1), on one side of which is disposed a reflective layer (4) and on the other side of which is disposed a protective covering (2). A separate protective covering (3) is applied to the core (1) between the reflective layer (4) and the core (1). The reflective layer (4) is a foil which is applied to the latter protective covering (3).

Abstract: An evaporating device comprises sets of solar heating units of a type having an insulated oblong room provided at the top with a slit, a mirror structure mounted on said room and a pipe extending through said room. Pipes from the units of a set form together a vapor pipe. Said evaporating device comprises a regulating valve mounted on each end of said vapor pipe. Said evaporating device comprises liquid supply means, which means comprise supply pipes forming branch pipes, a flow-rate regulating valve mounted on each of said branch pipes and an injecting device mounted on said branch pipes and connecting, near to an end of each unit, to the vapor pipe, said injecting device presenting an injecting opening directed axially in said vapor pipe, in the direction of said unit.
