Abstract: Die Erfindung betrifft ein Verfahren zur Herstellung von SE-Metallen und SE-haltigen Legierungen mit dem Ziel, die bekannten Vorteile metallothermischer Reduktionsverfahren zu nützen und gleichzeitig entscheidende Verbesserungen im verfahrens-technischen Ablauf der Reduktion zu bringen. Außerdem soll erfindungsgemäß erreicht werden, daß sowohl die reinen SE-Metalle als auch deren verschiedene Legierungen, insbesondere die Nd-Fe-B-Legierung nach ein- und demselben Verfahren herstellbar sind. Dieses Ziel wird dadurch erreicht, daß nach dem erfindungsgemäßen Verfahren die Reduktion der SE-Halogenide und/oder SE-Oxide einzeln oder als Gemisch, gegebenenfalls mit Legierungszusätzen aus der Gruppe der Eisenmetalle und anderer Legierungszusätze sowie gegebenenfalls mit Zusätzen von Alkali- und/oder Erdalkalimetallsalzen mittels eines oder mehrerer Erdalkalimetalle, bevorzugt aber Calciummetall, unter einer gegen SE-Metalle, SE-Verbindungen und Erdalkalimetalle inerten Atmosphäre in einem elektrischen Lichtbogenofen im zweiphasigen Ofenbetrieb erfolgt, wobei in diesem zur Erreichung einer möglichst raschen und vollständigen Reduktion auf Grund des entsprechend gewählten Strom-Spannungsverhältnisses eine starke Rührwirkung in der Schmelze durch elektromagnetische Kräfte erzeugt wird.

Abstract: A driving wheel slip control system for a vehicle detects an excessive slip state of at least one of the driving wheels of the vehicle wherein the slip of the driving wheel has a magnitude greater than a predetermined magnitude, and reduces engine output when the excessive slip state is detected, by repeating alternate fuel cut and fuel supply such that fuel supply is stopped for a first predetermined time period, and then effected for a second predetermined time period. During the second predetermined time period the engine is supplied with an amount of fuel smaller than one required for an operating condition of the engine in the excessive slip state. The first and second time period ratio and the fuel amount may depend upon engine parameters e.g. engine rotational speed and/or pressure in intake passage, or slip state. If the excessive slip state has a greater variation in magnitude than a certain value, fuel supply is continuously effected for a third predetermined time period longer than the first predetermined time period or all the time during the excessive slip state. When the driving wheel has left the excessive slip state, engine output is reduced below a value required for an operating condition of the engine.

IPC: C01F7/16

Abstract: Oxide ceramic products which, due to their finely divided character, are particularly suitable for powder-metallurgical moulding even at relatively low calcining temperatures. During the preparation process, organic phases some of which only decompose at elevated temperatures are formed from the corresponding hydroxide mixtures in alcoholic suspension. This prevents the melting of hydroxides having low melting points, as a result of which the powders do not have to be ground nor do they lose their sinterability. As shown by a number of examples, the process is not limited to the production of a few products but can be applied to the entire area of binary and multinary oxide ceramics. Moreover, the process is distinguished by simple process steps which are free of toxic substances.

Abstract: In einem Verfahren zur Gewinnung von p-Xylol mit einer Reinheit von mindestens 99,5 % wird von einem Vorprodukt aus gegangen dessen p-Xylolgehalt mindestens 99% beträgt. Dieses Vorprodukt wird im flüssigen Zustande in eine inerte Flüssigkeit, vorzugsweise Wasser, eingeleitet, deren Temperatur unterhalb des Schmelzpunktes des reinen p-Xylols liegt. Die sich dabei abscheidende Kristallphase wird von der Flüssigkeit abgetrennt und aufgeschmolzen. Die Schmelze besteht dabei aus p-Xylol mit einer Reinheit von mindestens 99,5%. Ausserdem wird hierbei die als Kälteträger verwendete inerte Flüssigkeit mit dem als Einsatzmaterial dienenden Vorprodukt, das einen hohen p-Xylolgehalt aufweist, in einem Mischbehälter unter Rotation zusammengeführt. Anschließend wird das Gemisch durch Filtration bis auf einen Kristallanteil von 3o bis 7o % eingedickt und danach die p-Xylolkristalle in einer Trenneinrichtung abgetrennt. Durch Erwärmung dieser Kristalle in der Trenneinrichtung kann die Reinheit des erzeugten Produktes gesteigert werden.

Abstract: Control device for a movable straw baler (1) with a press plunger (13) which can be driven via an eccentric mechanism in connecting rods (14P), and with a controllable press-channel resistance which can be regulated as a function of a press-pressure signal. The press-pressure signal is determined by position sensors (210, 211) which indicate the position of the abutment carrier (17) of the eccentric mechanism. A control signal for a steering actuator (44) is generated from the difference signal of the press-pressure signals. Further position sensors (42, 43) determining a lateral plunger displacement serve for the steering control and press-pressure control. <IMAGE>

IPC: H01H1/50
Filed: 1989-05-04
Abstract: The invention relates to a temperature-sensitive commutation device for an electronic component, such as a motor for driving window blinds, which is to be protected against excess temperature due to a fault, having a first bimetal switch and a resistor connected in parallel with the latter, so that, after the opening of the bimetal switch due to an excess temperature, the current flows across the resistor, generates heat and the bimetal switch is thus kept open due to the generation of heat of the ohmic resistor, even when the excess temperature which initially triggers the switching process and is brought about by a fault function of the electronic component to be protected falls. To protect the first temperature detector, the invention provides that a further, self-resettable temperature detector (56, 57, 58) is connected in series at least with the resistor (16, 20), said temperature detector having an opening temperature above that of the first detector (64; 12, 13) but substantially below temperatures which bring about irreversible damage to bimetal elements (12, 57), the two detectors (56, 64) being in close thermal contact.
