Übersetzung der PatentansprücheTranslation of patent claims 1. Strahlungsheizofen, enthaltend ein Gehäuse, welches in zumindest zwei Teile aufgeteilt ist, die bewegbar so angeordnet sind, daß sie zusammengeführt werden können, um eine zu erhitzende Probe zu umschließen, wobei jedes Teil wenigstens eine im wesentlichen sich längserstreckende Strahlungsheizqueile aufweist, so daß die Probe an zumindest zwei gegenüberliegenden Seiten gleichmäßig erhitzt werden kann.1. A radiant heating furnace comprising a housing divided into at least two parts which are movably arranged to be brought together to enclose a sample to be heated, each part having at least one substantially longitudinally extending radiant heating source so that the sample can be heated evenly on at least two opposite sides. 2. Strahlungsheizofen nach Anspruch 1, bei dem die Heizquelle eine Heizelementeanordnung enthält, die mehrere Lampen, wie Quarz-Halogen-Lampen aufweist, welche so betrieben werden, daß sie einen wesentlichen Teil ihrer Energie im Infrarot-Bereich abstrahlen, und welche entlang der Innenseite eines im allgemeinen länglichen, schalenförmigen Reflektors angeordnet sind, dessen innere Oberfläche so geformt ist, daß sie die Verteilung der Heizquellenelemente kompensiert.2. A radiant heating furnace according to claim 1, wherein the heat source includes a heating element assembly comprising a plurality of lamps, such as quartz halogen lamps, operated to emit a substantial portion of their energy in the infrared region and arranged along the inside of a generally elongated, bowl-shaped reflector, the inner surface of which is shaped to compensate for the distribution of the heat source elements. 3. Strahlungsheizofen nach Anspruch 2, weiterhin enthaltend Steuermittel zum Steuern der Energiezuführung zu den Lampen, um die Verteilung der Energie in verschiedenen Bereichen des Ofens zu variieren.3. A radiant heating furnace according to claim 2, further comprising control means for controlling the power supply to the lamps to vary the distribution of the power in different areas of the furnace. 4. Strahlungsheizofen nach Anspruch 2, bei dem die Lampen in einer Linie entlang des Reflektors angeordnet sind, und bei dem die Enden der "Schalenform" in einer "einspringenden" Form tief gebogen sind, um den "Abfall" in der Leistung an jedem Ende des linearen Bereichs der Lampen zu kompensieren, so daß die maximale Konzentration der Hitze an oder nahe der Vorderöffnung des Reflektors erfolgt.4. A radiant heating furnace as claimed in claim 2, wherein the lamps are arranged in a line along the reflector and wherein the ends of the "cup shape" are deeply bent in a "re-entrant" shape to compensate for the "drop" in power at each end of the linear range of the lamps so that the maximum concentration of heat occurs at or near the front opening of the reflector. 5. Strahlungsheizofen nach Anspruch !,enthaltend eine einzelne "Linearn-Lampe, die in einem länglichen, schalenförmigen Reflektor angeordnet ist, der an jedem Ende geeignet gebogen ist, um die weniger gleichmäßige Energieverteilung in diesem Bereich der Lampe zu kompensieren.5. A radiant heating furnace according to claim 1, comprising a single "Linear n" lamp arranged in an elongated, bowl-shaped reflector which is suitably curved at each end to compensate for the less uniform energy distribution in that region of the lamp. 6. Strahlungsheizofen nach einem der vorstehenden Ansprüche, bei dem das Gehäuse zwei Hälften umfaßt, welche schwenkbar an Haltemitteln so angeordnet sind, daß sie in Anlage aufeinander zu geschwenkt werden können, um einen zu erhitzenden Gegenstand zu umschließen, wobei jede Hälfte ein Paar an einstellbar angeordneten Heizelementanordnungen trägt, welche in Richtung auf das Zentrum des Ofens ausgerichtet sind und weiche relativ so zueinander angeordnet sind, daß bei im Ofen aufgenommenem Gegenstand sie den Gegenstand im wesentlichen umgeben.6. A radiant heating oven according to any preceding claim, wherein the housing comprises two halves pivotally mounted on support means so that they can be pivoted into engagement with one another to enclose an article to be heated, each half carrying a pair of adjustably arranged heating element assemblies which are directed towards the centre of the oven and which are arranged relative to one another so that when an article is received in the oven they substantially surround the article. 7. Strahlungsheizofen nach einem der Ansprüche 1 bis 5, bei dem das Gehäuse vier axial sich erstreckende .Heizelementeanordnungen aufweist, von denen jedes einen Quadranten eines bezogen auf die Heizachse seitlichen Querschnitts durch den Ofen umfaßt und mit einer gleitbaren Halterung versehen ist, die es gestattet, seine Position zumindest in einer radialen Richtung und vorzugsweise auch in einer Umfangsrichtung relativ zur Achse einzustellen.7. Radiant heating furnace according to one of claims 1 to 5, in which the housing has four axially extending heating element arrangements, each of which comprises a quadrant of a lateral cross-section through the furnace with respect to the heating axis and is provided with a slidable support which allows its position to be adjusted at least in a radial direction and preferably also in a circumferential direction relative to the axis. 8. Strahlungsheizofen nach Anspruch 6 oder 7, bei dem die Heizelementeanordnungen so geformt und angeordnet sind, daß sie zusammenwirken, um den zu erhitzenden Gegenstand im wesentlichen einzuschließen, wenn das Gehäuse geschlossen ist, und um den Strahlungsheizleistung an einem einstellbaren Brennpunkt in dem Mittenbereich zu konzentrieren.8. A radiant heating oven according to claim 6 or 7, wherein the heating element assemblies are shaped and arranged to cooperate to substantially enclose the object to be heated when the housing is closed and to concentrate the radiant heating power at an adjustable focal point in the central region. 9. Strahlungsheizofen nach einem der Ansprüche 6 bis 8, bei dem jede Heizelementeanordnung einen Metallkörper enthält, weicher so gestaltet ist, daß er die erforderliche Reflektorform bildet und auch die Innenkanäle für die Zirkulation eines Kühlfluids bildet, so daß eine gesonderte Kühlummantelung nicht erforderlich ist.9. A radiant heating furnace according to any one of claims 6 to 8, wherein each heating element assembly includes a metal body which is designed to form the required reflector shape and also to form the internal channels for the circulation of a cooling fluid, so that a separate cooling jacket is not required.
