Abstract: The present invention discloses a method for setting a disc-shaped diamond or other precious stone that provides increased stability and resistance to breakage, thus protecting the precious stone and minimizing the possibility that the setting may break or fail. The setting is accomplished by holding the disc-shaped stone onto an article of jewelry via a cap located on a distal end of a rod that extends through the center of the disc-shaped stone and is welded at a proximal end to a face of the article of jewelry. The disc-shaped stone is thus secured between the cap and the article of jewelry such that it is in contact with each, thereby preventing axial movement along the rod. These settings as described may be disposed at as many positions about an article of jewelry as so desired.

Abstract: This invention relates to a control system for heat supply as hot water from nuclear power plants equipped with condensation units. This leads to the increased efficiency of the nuclear power plant on the basis of heat extraction from the turbine and its utilization for district heating with hot water as agent. The system requires a turbine nonadjustable bleeding through which a steam flow is extracted. A flow nozzle for steam flow measurement is provided on the steam transport line, a pressure transducer which sends a signal to a comparing and control unit which receives also a signal from another pressure transducer located on the turbine first stage. The comparing and control unit actuates the motorized steam and condensate valves, performing the turbine protection in case that the steam flow extracted at the nonadjustable bleeding exceeds the allowed limit.
