摘要： A heating chamber (1) for a heating furnace is proposed, with which electrothermal vaporization of impurities from samples can be effected in order to be able to then analyze them spectrometrically. The heating chamber has a wall (3), a sample reception area (5), a nozzle area (7) and two electrical connection areas (9, 11). The heating chamber (1) is specially configured such that an electric current flows through the wall (3) in such a way that a heating capacity caused by it is higher in the nozzle area (7) than in the sample reception area (5). For example, the electrical connection areas (9, 11) may be arranged in a radial direction remoter from the longitudinal axis (8) than a part of the wall (3) surrounding the nozzle area (7), and the heating chamber (1) may be configured, for example by means of a locally constricted area (13), in such a way that the current between the two electrical connection areas (9, 11) is predominantly conducted radially inwards towards the part of the wall (3) surrounding the nozzle area (7). Advantageous heat distribution in the heating chamber (1) achievable thereby may have a positive effect on the analysis of sample impurities.

摘要： A remelting furnace is disclosed. An electrode rod drive with an electrode rod, as well as a retaining ring to retain a high-current cable, are arranged on a platform which is located on a weighing cell. Even though the position of the high-current cable changes during lowering of the electrode rod supporting a consumable electrode, the recorded weight portion of the high-current cable remains the same, which means that ultimately the change in the weight of the consumable electrode can be determined with the weighing cell.

摘要： A furnace for treating granular activated carbon comprises a single vertical column having a pair of electrodes arranged at vertically spaced locations within the column. The electrodes extend across the column and are so constructed that the particulate material can pass with ease through the electrodes. Suitable connectors connect the electrodes to a source of rectified three phase electric power. Pointed prongs are provided below the upper electrode. A valve controls the outlet from the column so that the furnace can operate continuously. A central cone is provided above the outlet to control the flow of granular carbon down the column.

摘要： Disclosed is a mold structure for casting large metallic parts such as ingots so as to avoid the formation of the "shrinkage pipe" which normally develops on the exposed top surface of such castings during their solidification. The structure comprises a cap for placement on a mold which includes a diaphragm having a front surface located to intercept radiation emitted from the top surface of the cooling metal mass and to reemit radiation back thereto, and a means for returning radiation emitted from the back surface of the diaphragm such as an infrared reflector or a stack of baffles. The cap may include means for cooling the reflective surface and suitable ports which allow the interior of the mold and cap to be evacuated. Portions of the mold adjacent its open top may be provided with insulation to prevent heat loss from the metal by conduction. Various means for providing make-up heat to the top surface of the metal mass may also be included in the structure.

摘要： The rotary drum of reactivation apparatus has spaced-apart helical electrodes disposed in mutually interposed helical state and fixed to the inner wall surface of the drum, these electrodes functioning upon rotation of the drum to propel by screw action active carbon from an inlet end to the other outlet end of the drum as electric power is supplied to the electrodes to cause electric discharge therebetween and conduction through the carbon, which is thereby subjected sequentially to drying, firing, and reactivation as a result of electric discharge effect and the resulting joule heat. Flow of excessive current between the electrodes is prevented by a constant-current circuit in the electric power supply system. Steam can be additionally injected against the carbon to promote the reactivation thereof.

摘要： The invention relates to an electric salt bath furnace for reclamation of copper or other nonferrous metal from ferrous or other higher melting scrap containing the same. A standard type or ceramic lined salt bath furnace having electrodes for passage of current through the bath is provided with an additional electrode at the floor of the furnace. Said electrode has a discharge conduit within the same through which the molten metal is withdrawn, emerging therefrom as solid metal. During initiation of the molten metal discharge, the temperature of the entrance end of the conduit is maintained above the melting point of the metal by the heating effect of the current through the floor electrode. During the casting, the current through the floor electrode is discontinued to avoid overheating and the electrode is discontinued to avoid overheating and the electrode can be water cooled, if necessary. Sensors, preferably thermocouples, are arranged in proximity to said floor electrode to measure the temperature and to control heating and cooling of the metal passing through the discharge conduit.
