Title: Concrete with very high compression strength - made using sand consisting of porous roasted clay
IPC: C04B14/12
Filed: 1973-10-19
Abstract: Concrete with high compression strength is obtd. by mixing fine gravel possessing a high compression strength, sand, cement and water, the novelty being the use of a porous ceramic sand such as roasted clay having a grain size of 0.1-5mm and pores of 0.5-15 mu dia. which are larger than the size of the cement grains used. One pref. cement is CPA 400 HTS used with a sand having pores 0.5-2 mu dia. where 65% of the pores are 1-1.5 mu dia. Alternatively, cement CPA 400 is used with sand having pores 1-15 mu dia. where 60% are 5-10 mu dia.; 'Cement Pondu' may also be used with sand having pores of 1-15 mu dia. where 60% are 5-10 mu. The roasted clays are pref. kaolinic or illitic clays or marls. Artificial sand 0.1-5mm size may be used with porphyritic gravel, 5-18mm in size. Very high compression strength can be obtd. and the process is easily carried out on a construction site. Due to the strength, the size of concrete structures can be reduced.

Title: Energy-producing installation, partic. nuclear - including steam generator, turbine, and vapour recycle, incorporates vapour compression and auxiliary superheat
Inventor: PACAULT PIERRE HENRI
IPC: F01K3/26
Filed: 1975-05-23
Abstract: A process and plant for improving an energy-producing installation with vapour recycle, which includes a steam generator fed with heat from a basic source, partic. nuclear, and a turbine fed with steam from the generator, incorporate two operating modes. The first consists of taking live steam from the generator, compressing it mechanically and transferring at least a part of the heat to the working fluid. The second consists of transferring heat from an auxiliary fluid to the working fluid. The auxiliary fluid is heated by an independent source, separate from the basic source. The combination of the two modes results in the superheating of the working fluid before it goes to the turbine and between the two stages of the turbine. The auxiliary fluid may be steam, and the heating may be brought about by a heat accumulator supplied with heat from a fossil combustible or an electrical resistance. The invention combines the two known methods of superheating the steam produced at relatively low pressures from vapour-recycle energy-producing systems, partic. nuclear stations. It therefore takes advantage of the benefits of both methods.

Patent FR-2279306-A1 (FR)
Inventor: KRALL BOGDAN
IPC: H01L21/60
Filed: 1975-06-03
Abstract: A method for joining microminiature components to a carrying structure wherein the height of the electrical connecting structures are adjusted during the joining process. The height of the electrical connecting structures may either be adjusted during the original joining of the component to the carrying structure or it may be done in a two step solder reflow process. In the two step process the component is first joined to the carrying structure and then an additional height is given to the electrical connecting structures which improves the lifetime of the joining terminals. In each of the alternatives, a bridge together with a vaporizable fluid which wets both the bridge and a surface of the component opposite to the surface which carries the connecting structure. At the temperature of melting of the material used in the connecting structure, the fluid evaporates and surface tension pulls the component closer to the bridge which in turn elongates or increases the height of the electrical connecting structures between the carrying structure and the component.
