    Abstract: For the continuous melting of silicon granulate for a band drawing method, a melt reservoir in communication with the melt crucible based on the principle of communicating vessels, is provided in the form of a thermally insulated, annular crucible in whose center axis a rotary plate to be centrifugally accelerated is arranged, the speed thereof being continuously varied. Two pipe parts connected to one another at an angle between approximately 45.degree. to about 90.degree. are secured on the rotary plate, the one, vertical pipe part thereof serving as admission in the rotational axis and the other pipe part thereof forming the acceleration path for the granulate particles in the direction toward the annular melt crucible. On the basis of this arrangement, a uniform delivery and melting of the granulate particles in the melt surface is achieved and, thus, a continuous silicon band drawing with uniform layer thickness is enabled. The arrangement is used in the manufacture of silicon bands for solar cells.

    Abstract: An apparatus for melting solids which is particularly designed to melt tar billets without overheating and thus causing pyrolysis of the solid tar. The apparatus in its principal embodiment utilizes a solid horizontal plate having a plurality of parallel ridges separated by parallel fluid conducting channels, the plate being heated from beneath by a special burner arrangement and causes the tar to melt and then drain into a collector trough rather than remain adjacent the heating surface. The apparatus utilizes vertical feed tar billets which are forced against the melting plate under action of gravity with or without auxillary pressure applying means, and a specialized burner, manifold and stack structure provide for proper removal of burned gases while allowing the easy loading of the vertically stacked tar billets.

    Abstract: A high temperature reactor is fitted with a plasma gun at an anode chamber and is provided with a graphite cathode. The reactor is cooled by means of pipes in the refractory lining of the reactor, and rests on essentially horizontal bearings. The charge to be melted e.g. oxides or oxide mixtures is fed from above at an angle .alpha. at most 90.degree. to the main axis of the reactor in the direction of the plasma stream, and the molten product is tapped off at an exit port which is also close to the entry port of the plasma stream so that the plasma stream covers and therefore heats the area around the exit port.

    Abstract: A process and apparatus for treating materials, such as solid, particulate material, wherein the particulate material is introduced into a heat transfer medium, the density of such medium being different from that of the particulate material and the temperature of such medium being higher than that of the particulate material when so introduced. The particulate material, the individual particles of which are preferably introduced separately, travels through the medium and becomes heated thereby to a generally flowable state. The flowable particles of the particulate material thereupon leave the fluid and coalesce to form a flowable mass thereof external to the heat transfer medium.
