A gating system for adding an alloying material to a molten base metal in immediate connection with a casting process. An encoded region designator selects the region that is to be encoded, in the input image, depending on the bit rate of the transmission path. A thermistor bead temperature sensor is encapsulated in a metal housing, which is in turn mounted on a carrier. The fuel injected into the manifold also undergoes intense mixing as it passes through the turbocharger. As the seeds germinate and grow, they grow upwards out of the base component and provide jewelry with living, growing, renewable ornamental materials.
