Title: Roof tiles as solar collectors
IPC: F24J2/04
Filed: 1984-02-11
Abstract: For most house-owners, solar collectors are too expensive, and disfigure the roofs. They disfigure our very beautiful tiled roofs. As a remedy, it is proposed according to the invention that the roof tiles contain cavities through which metal pipes can be laid. If water is passed through these, it takes up the heat which is stored by the roof tiles. In order to facilitate the storage of heat, solar roof tiles must be compact, and be compressed as hard as possible. For laid tiles, and laid solar roof tiles, the pipes are preferably to face from above to below, as following the longitudinal direction of the solar roof tiles. Optimum colouring to trap the solar radiation is important. A layer of air between the roof tiles, the solar roof tiles, and the glazing or glass surface situated above them protect against heat losses. Constituent materials of the solar roof tiles convert UV rays etc. into heat, for better utilisation of the solar radiation. The solar roof tiles are to be flat.

Title: Fuel plate for assembling light-water reactor cores, and process for the manufacture thereof
Inventor: SPALTHOFF WERNER DR
IPC: G21C21/02
Filed: 1984-10-06
Abstract: The invention relates to a fuel plate for assembling cores of light water-cooled nuclear reactors and a manufacturing process for the fuel plate. The object of the invention is to ensure, in the case of a fuel plate having a cladding made of a zirconium alloy and a fuel layer which comprises uranium dioxide as a nuclear fuel-containing material, a firm union between fuel layer and cladding and thus effective heat removal from the nuclear fuel, so that no significant overheating with respect to the cooling water, resulting in the detrimental release of fission gas, can take place in said fuel. When the plates are manufactured, the fuel layer is applied by means of a spray process on to the inside of the cladding present as sections, and the sections are then welded together. The spray process, in its application according to the invention, essentially comprises injecting the ceramic or metallic fuel layer material in powdered form into a plasma beam, where it heats up in fractions of a millisecond and in the partly fused or fused state is flung on to the substrate to be coated, where it solidifies virtually at the moment of impact. The plasma gases used are preferred noble gases.
