Title: Device for preparing single crystal
Inventor: FUJII TAKASHI
IPC: F16J12/00
Filed: 1984-06-20
Abstract: PURPOSE:To obtain a titled device capable of exchanging seed crystal while maintaining a starting material of the crystal in a molten state by providing shutters for separating an autoclave into three sections in the pulling direction of the crystal and constructing each sectional chamber so as to be able to adjust the pressure independently while holding the shutters in a closed condition. CONSTITUTION:For example, GaAs melt 3 and B2O3 soln. 4 as a liq. sealing material are formed in a crucible 2 while communicating three chambers A, B, C by opening shutters 91, 92. Then, the crucible 2 is fitted to a supporting shaft 8 and the pressure inside of the autoclave 1 is elevated to about 30atm by gaseous Ar, and a seed crystal 7 is pulled in a hot condition while contacting with the melt 3. If exchange of the crystal is necessary, the crystal 7 is lifted upto a working chamber C by a pulling shaft 6 and the shutters 91 and 92 are closed. Then inert gas is fed to a separating chamber B to elevate the pressure to higher than the pressure of a crucible housing chamber A, then the gas in the chamber C is replaced with inert gas having the same pressure as the atmospheric pressure. The cover 15 is opened and the crystal 7 is exchanged. Accordingly, the exchange of the seed crystal is facilitated, and workability of pulling the crystal and the yield of the crystal are improved.

Title: Treatment of metal-containing waste
Inventor: YOHAN SUBUERU REIRUNESU
IPC: C22B1/00
Filed: 1982-07-21
Abstract: The invention relates to a method for converting metal-containing waste material having substantial quantities of organic constituents, such as plastics, rubber, paper and greases, to a product from which metal can readily be recovered. The waste material is introduced into a reactor vessel arranged for rotation about its longitudinal axis, the vessel being provided with a bottom and a common charge and discharge opening, whereafter the reactor vessel is rotated with its axis inclined to the horizontal plane at an angle of less than 90 DEG . The reactor vessel is maintained during this rotation at a temperature which is sufficiently high to expel organic constituents in the form of a combustible gas for as long as such a gas continues to be generated. The combustible gas is combusted continuously at a location external of the reactor vessel, and the residual content of the reactor vessel is taken out in a molten and/or non-molten state. During at least a part of the expulsion process, air or gas containing free oxygen can be supplied to the reactor vessel through a lance in sub-stoichiometric amount.
