A method and an apparatus are disclosed for detecting a first substance within a second substance, preferably for localizing diamonds in kimberlite rocks. The first substance, e.g. the diamonds, have a very long spin-lattice relaxation time (T1) in the order of hours. For rapidly detecting the first substance, the build-up of magnetization of a predetermined kind of nuclei, e.g. 13C, being abundan...

A photovoltaic generator device for producing an output sufficient to turn on a MOS-gated device consists of a plurality of planar photogenerators connected in series. Each of the photovoltaic generators is contained on its own respective insulated tub. The insulated tubs are formed by wafer bonding a junction-containing wafer to a handle wafer with a dielectric isolation layer between them. The i...

The filtering device eliminates the problems which occur with similar known devices. It is built entirely in easily bonded thermoplastic materials which are resistant to attack by acids and practically indestructible. Furthermore, its maintenance is simplified by the fact that the filter drum 2 is easy to extract without removing the butterfly valve 6 which permits self- washing, but solely by mea...
