Claims (1)

<Desc/Clms Page number 2> <Desc / Clms Page number 2> 3. Elektrischer Ofen nach Anspruch 2, dadurch gekennzeichnet, dass der Bettungssand bei seinem Setzen oder Zusammenschütteln auf einem mit dem Ofen verbundenen Vorratsbehälter nachgeschoben wird, um die Bildung von die Heizkörper blosslegenden Hohlräumen zu verhindern. 3. Electric furnace according to claim 2, characterized in that the bedding sand is pushed after it is set or shaken together on a storage container connected to the furnace in order to prevent the formation of cavities that expose the radiators. 4. Elektrischer Ofen nach Anspruch 3, dadurch gekennzeichnet, dass der Vorratsbehälter durch den von Heizkörpern freien oberen Teil des Ofens gebildet wird. 4. Electric furnace according to claim 3, characterized in that the storage container is formed by the upper part of the furnace free of radiators. 5. Elektrischer Ofen nach Anspruch 4, dadurch gekennzeichnet, dass der Ofen aus mehreren, den Bettungssand und die Heizkörper enthaltenen, aufrechtstehenden, rohrartigen Gefässen besteht, die mit ihren oberen Enden in den gemeinsamen Vorratsbehälter münden. 5. Electric furnace according to claim 4, characterized in that the furnace consists of a plurality of upright, tubular vessels containing the bedding sand and the radiators, which open with their upper ends into the common storage container. 6. Elektrischer Ofen nach Anspruch 3, dadurch gekennzeichnet, dass sich der Vorratsbehälter nach unten trichterförmig verjüngt, so dass die Bettungsmasse durch ihr Eigengewicht in die Widerstandsbehälter nachfliesst. 6. Electric furnace according to claim 3, characterized in that the storage container tapers downwards in the shape of a funnel, so that the bedding compound flows into the resistance container by its own weight. 7. Elektrischer. Ofen für explosionsgefährliche Räume, dadurch gekennzeichnet, dass der Luftraum des Ofeninneren mit einem nicht feuergefährlichen Nebenraum in Verbindung steht. 7. Electric. Furnace for explosive rooms, characterized in that the air space of the furnace interior is connected to a non-flammable adjoining room. 8. Elektrischer Ofen nach Anspruch 7, dadurch gekennzeichnet, dass der Luftraum des Ofeninneren unter schwachem Überdruck gehalten wird. EMI2.1 8. Electric furnace according to claim 7, characterized in that the air space of the furnace interior is kept under slight overpressure. EMI2.1
