Patent FR-2284167-A1 (FR)
IPC: G21C1/00
Filed: 1975-09-04
Abstract: An integrated pressurized-water reactor and steam generator is disclosed, particularly for ship propulsion and smaller stationary installations, in which circulating pumps of primary coolant loops are arranged in the upper part of a vertical pressure vessel close to the vessel's removable head. An annular steam generator is arranged centrally within the vessel, and above the outer periphery of a reactor core in the vessel's lower portion, and is suspended via a separate hollow ring supported by the vessel's upper portion and in which the impellers of the circulating pumps are arranged. The primary cooling water flows upwardly through the reactor core and the heat exchanger to the pumps located above, and from there, through a separate ring passage outside of the heat exchanger housing and core downward to again flow upwardly through the reactor core. Secondary steam and primary feed water nozzles can be disassembled sideways, so that although normally connecting with internal parts, all internals can be removed upwardly from the pressure vessel so that the pressure vessel can be checked everywhere. In the event of a failure of the circulating pumps, the afterheat given off by the reactor core after being shut down, is transmitted to the heat exchanger through natural thermal circulation of the water in the vessel.

Title: Heat engine water leaks detection system - uses compressed air and rotating bobbin to deflect rubber seals
IPC: G01M3/06
Filed: 1977-05-05

Du métal est alors déposé sur la structure et éliminé sélectivement par la technique de décollement. Certaines portions métalliques 22C viennent en contact avec le substrat, d'autres 22A sont isolés. En répétant cette opération, ce procédé permet d'obtenir des structures de circuits intégrés avec de fortes épaisseurs d'oxyde.

Title: Heat pump drawing energy from atmosphere - has glass covered absorber with temp. responsive control to regulate refrigerant flow through gap
IPC: F24S10/75
Filed: 1977-09-02
Abstract: A refrigerant circulated in a heat pump passes through an evaporator which has a large black absorber surface. When bright sunshine coincides with low air temperatures, the absorber is covered by a sheet of glass which is transparent to solar radiation but not to low temperature radiation. A suitable insulator prevents conduction or convection from the absorber surface to the atmosphere through the glass. At high ambient temperatures, a good conducting medium is introduced between the cover and the absorber so that the heat of the air is used to evaporate the refrigerant. The change from one heat source to the other is effected automatically in accordance with the ambient temperature.
