Abstract: A method and apparatus for heating molten steel in a steel making operation is disclosed, and which includes a refractory lined vessel (12) having an open top, a removable cover (30) adapted to overlie the top, and at least one plasma arc torch (34) mounted so as to extend through the cover at an angle of about 60°. The arc gas for the torch includes a substantial percentage of nitrogen, which permits a higher power level as compared to conventionally used argon, and the mass flow rate of the arc gas is maintained at a sufficiently high level to produce a continuous blast of gas which impinges at an angle upon any slag formed on the surface of the molten steel with sufficient force to move the slag and expose the underlying molten steel. As a result, the attachment of the arc to the underlying molten steel is facilitated, and the impingement of the gas contributes to the mixing of the steel to avoid heat stratification.

Abstract: With respect to an AlGaAs material as an example, there is disclosed a compound semiconductor structure in the form of superlattice film with graded Al mole fraction, comprising an alternating deposition of an AlGaAs layer containing Al and a GaAs layer containing no Al, the thickness ratio between a pair of said layers being gradually varied in the direction of thickness throughout successive pairs, forming a compound semiconductor structure with substantially graded Al mole fraction. A process for preparing such a semiconductor structure is also disclosed. When the above film is heat-treated, Al in the AlGaAs layer diffuses into the GaAs layer, yielding a film with more smoothly graded Al mole fraction.

Abstract: The present invention provides a rotary drum filter wherein one or preferably two rotary drum filters (10, 12) are submerged in a tank (18) of liquid to be filtered (16). Each rotary drum filter is comprised of a generally cylindrical tank having a perforated outer wall plate (22) over which is applied a cloth type filter media (28). A suction pipe (46) is included inside the rotary drum filter so that filtered liquid can be drawn into the rotary drum filter through the pressure differential established by the suction pipe. Clean filtered liquid exits the suction pipe to the industrial apparatus with which the filter apparatus is used. A backwash vacuum box (90) extending generally the length of the rotary drum filter media is in contact with a portion of the rotary drum filter media. A partial vacuum is established in the vacuum box such that filtered liquid can be drawn outwardly from the rotary drum filter such that solids accumulated on the filter media are drawn off from the filter media thereby cleaning that section of the filter media. Drive means are provided to rotate the rotary drum filter so that the backwash vacuum box is exposed to the entire circumference of the rotary drum filter upon one complete revolution of the rotary drum filter.

Abstract: A programmable logic array includes a dynamic AND plane, and an OR plane using clocked load devices (M17...M20). The high precharge voltage state in the AND plane places the logic lines in the OR plane (00...03) in a low voltage state during precharge. The OR logic lines may then be pulled to a high level during the decode operation. A single clock having a delay path (AR) may be used to control the precharge and decode operations of the PLA.

Abstract: La présente invention, qui a pour but d'empêcher les dommages causés par le pétrole dans des eaux à ciel ouvert, est fondée sur le principe que la viscosité du pétrole change en fonction de la température. La figure I montre le principe de fonctionnement. Une embarcation de type catamaran est pourvue de deux cylindres (2) maintenus à une température inférieure à l'eau à l'aide d'unités de refroidissement (5). Le pétrole (7) qui flotte dans l'eau entre en contact avec le cylindre (2), se congèle et adhère à la surface du cylindre. Comme le cylindre tourne, le pétrole est transporté à la surface du cylindre jusqu'à atteindre une gouttière de récupération chauffée (8) où il est recueilli. Il est ensuite dirigé depuis la gouttière dans un réservoir collecteur disposé dans l'embarcation. Les dimensions des embarcations, des cylindres et de l'unité de refroidissement peuvent être choisies librement selon les conditions.

Abstract: Procédés et appareils de détermination de la conductivité d'une formation souterraine (120) traversée par un puits (110), en particulier un puits tubé. Des variations de la conductivité du tubage et/ou du placement des électrodes, dues par exemple à des contraintes ou des dilatations thermiques ou à la corrosion sont compensées. La compensation consiste à obtenir des tensions développées en réponse à un courant passant entre des électrodes de courant à espacement relativement serré (124, 126) et à utiliser ces tensions pour compenser les tensions développées en réponse à un courant s'écoulant entre des électrodes de courant (122, 130) plus éloignées. Des modifications sont décrites pour permettre des mesures de la conductivité dans des puits partiellement tubés ou non tubés, ou dans des puits en cours de forage.

Abstract: An impact attenuation device for catching and retarding vehicles in front of obstacles next to a road has transverse frames (1) which are arranged one behind the other at a distance, are each situated on an upright (5) and can be displaced with the latter in the longitudinal direction, so that side plates (4) which are mounted laterally on the transverse frames and overlap in imbricated fashion are pushed one inside the other in the manner of a telescope. The upright (5) is designed as an element (2) having an essentially rhomboid cross- section and deforming plastically upon impact, during which deformation the supported transverse frame (1) is raised against the clamping resistance of guide cables (6) clamping behind the side plates (4) (right in the figure). A clamping device (9), which is arranged on a longitudinal guide rail (10') between the transverse frame (1) and the retaining piece (14) of the upright (5), counters this lifting movement with frictional resistance. <IMAGE>

Abstract: Um den Läuferwiderstand einer Drehfeldmaschine zu bestimmen, wird im Ständer über eine feldorientierte Regelung ein Strom eingeprägt, der in Richtung des Flusses einen harmonischen, über der Nennfrequenz der Maschine liegenden Anteil besitzt. Aus Strom, Läuferlage und einem nachstellbaren Parameterwert für den Läuferwiderstand rechnet ein Strommodell eine feldparallele EMK-Komponente EF1 aus, deren harmonischer Anteil EF1~ isoliert wird. Zusätzlich rechnet aus Strom und Spannung ein Spannungsmodell feldparallele Komponente des EMK-Vektors als Stromkomponenten-Sollwert EF1' und deren harmonischen Anteil EF1 ? aus. Ein Korrekturregler CR1 stellt den Parameter rR des Läuferwiderstandes solange nach, bis die Differenz beider isolierten harmonischen EMK-Anteile verschwindet. Das Testsignal wirkt sich praktisch nicht im Fluß und im Drehmoment der Maschine aus. Gleichzeitig kann auch der Ständerwiderstand rS bzw. die Streuinduktivität xSt ermittelt werden.

Abstract: Known ceiling fans comprise a central shaft which is supported by two (ball)-bearings. This type of fan-designs requires perfect mounting handling and sometimes even high skillness. 
     The claimed ceiling-fan support system in stead is simple in design, less expensive and relative easy to assemble. These features are obtained due to the fact that a specific designed shaft (10) is applied which is supported at one end by a ball-bearing (11) and at its other end by a sliding bearing (12). Moreover the shaft (10) is provided with a disc-like member (8) to which the rotor housing (1) is connected.
