    摘要: A hydrostatic fan drive for internal combustion engines is disclosed, having a primary unit that can be driven by the internal combustion engine, and having a fan motor by means of which a blower fan can be driven. A hydraulic reservoir is disposed at a high-pressure line connecting the primary unit to the fan motor. A hybrid fan drive for internal combustion engines is thus provided, allowing fan operation even if the internal combustion engine is switched off. An increased maximal available power of the internal combustion engine is available in transition, despite the fan operation, because the fan motor can be supplied with pressurized media by the hydraulic reservoir in such cases (in transition).

    摘要: The invention relates to a method for controlling a hydrostatic drive having at least one first hydraulic consumer and one second hydraulic consumer. The two hydraulic consumers are driven by a common drive machine. First of all, a first power requirement of the first hydraulic consumer is determined (20). Proceeding from the determined first power requirement, the free power which is available as a result of the common drive machine is determined (21). This available free power of the common drive machine is scaled onto a possible actuating path of a control transmitter for the working hydraulics (22). A position of the control transmitter for actuating the second hydraulic consumer is determined (23) and a power requirement is assigned on the basis of the scaled available free power. An operating point of the common drive machine is fixed from the first power requirement and the second power requirement (24).

    摘要: The method of producing monocrystalline or multicrystalline blanks, especially silicon blanks, by using a vertical-gradient-freeze method, includes providing a crucible with a rectangular or square-shaped cross section and a heating jacket disposed around the crucible, which has a number of flat heating elements with a meandering course disposed on side faces of the crucible. The heating jacket generates an inhomogeneous temperature profile corresponding to a temperature gradient in the center of the crucible. The flat heating elements preferably comprise parallel heating webs, whose heat output is set by varying the conductor cross section. To avoid local overheating in corner areas of the crucible, constrictions of the cross section are provided at inversion zones of the meandering courses of the webs. The flat heating elements can be formed from a plurality of interconnected individual segments.

    摘要: The method provides CaF2 single crystals with low scattering, small refractive index differences and few small angle grain boundaries, which can be tempered at elevated temperatures. In the method a CaF2 starting material is heat-treated for at least five hours at temperatures between 1000° C. and 1250° C. and then sublimed at a sublimation temperature of at least 1100° C. in a vacuum of at most 5*10−4 mbar to form a vapor. The vapor is condensed at a condensation temperature of at least 500° C., which is at least 20° C. below the sublimitation temperature, to form a condensate. Then a melt formed from the condensate is cooled in a controlled manner to obtain the single crystal, which is subsequently tempered. The method is preferably performed with a CaF2 starting material including waste material and cuttings from previously used melts.

    摘要: The invention relates to a device and a method for the production of monocrystalline or multicrystalline materials using the vertical-gradient-freeze method, in particular silicon for applications in photovoltaics. According to the invention a low amount of wastage is achieved in that the cross section of the crucible is polygonal, in particular rectangular or square-shaped. Disposed around the circumference of the crucible there is a flat or planar heating element, in particular a jacket heater, which generates an inhomogeneous temperature profile. This corresponds to the temperature gradient formed in the centre of the crucible. The heat output of the flat heating element decreases going from the top end to the bottom end of the crucible. The flat heating element comprises a plurality of parallel heating webs, extending in a vertical or horizontal meandering course. The heat output from the webs is set by varying the conductor cross section. To avoid local overheating in corner areas of the crucible, constrictions of the cross section are provided at inversion zones of the meandering courses of the webs. The flat heating element can be formed from a plurality of interconnected individual segments.
