The support consists of a base (100) and a connector (200) for attaching it to a mobile unit on the X-ray machine. The base and the connector are made in one piece from an injection-moulded plastic which is transparent to X-rays pref. polycarbonate. The surface of the base can carry markings which are also transparent to X-rays, designed to facilitate positioning. The one-piece support can be made...

Reactive metal granules, especially of magnesium and/or magnesium alloys are produced directly from molten metal. The metal is fed under pressure to a granulation nozzle which forces the metal to aquire a circular motion of increasing velocity before it reaches the outlet of the nozzle and disintegrates successively into small fragments and droplets. These fragments and droplets are formed in an i...
