Filed: 1972-08-04
Granted: 1983-01-13
Abstract: The support system consists of a stationary track guide section (1) and a support magnet (2) which is fixed to the vehicle. The magnet (2) carries the main field exciter winding (3) in an iron section and has current carrying conductors (41,42) arranged in slots in the longitudinal face of the poles (22). These conductors may be separate or formed as one control winding. The track guide section (1), which is made of insulated laminations for high speed travel and high flux cross section, may be made in its simplest form with a rectangular shape. By insetting the control winding (4) in the faces (21) of the poles (22) of the support magnet the forces are exercised predominantly on the surfaces of the iron. Thus by the additional winding on the support magnet the side guiding of the vehicle can be effected without the expense of adding guide rails.PS.

Filed: 1980-05-23
Granted: 1989-06-15
Abstract: Data converter for a speech synthesizer system wherein encoded formant parameters as stored in a memory are decoded and transformed or converted to reflection coefficients in real time by means of a circuit implementing a Taylor series type approximation. The reflection coefficients are then quantized and input to a speech synthesizer which utilizes quantized reflection coefficients to synthesize speech. The use of the coded formant frequency speech data which inherently contains more speech intelligence than reflection coefficient speech data enables a speech synthesizer system which utilizes quantized reflection coefficients to operate at a significantly lower bit rate than would otherwise be possible where reflection coefficients are employed as the speech data stored in the memory.

Title: Verfahren zur Abtrennung von Aktinoidenionen aus wäßrigen, basischen, carbonathaltigen Lösungen

Granted: 1986-01-09
Abstract: Die Erfindung betrifft ein Verfahren zur Abtrennung von Aktinoidenionen aus wäßrigen, basischen, carbonathaltigen oder carbonat- und degradationsprodukthaltigen Lösungen unter Verwendung von basischen Ionenaustauschern. Die Abtrennung des Uranyltricarbonatokomplexes aus einer wäßrigen basischen Lösung kann durch Adsorption des Urankomplexes an stark basischen Anionenaustauschern durchgeführt werden, bringt jedoch Nachteile mit sich, wie z.B. eine verhältnismäßig niedrige Kapazität des Ionenaustauschers und eine verhältnismäßig schlechte Elutionscharakteristik. Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu schaffen, das sowohl bei der Adsorption des Uranylcarbonatokomplexes als auch bei der Desorption die Nachteile der bekannten Verfahren vermeidet und in bezug auf die Wirksamkeit diese übertrifft, weniger empfindlich auf Konzentrationsänderungen der CO ↓3 ↑2 ↑--Ionen reagiert und trotzdem einfach und leicht durchführbar ist. Dies wird dadurch erreicht, daß die Aktinoidenionen an einem schwach basischen Anionenaustauscher aus einer mit zu einem überwiegenden Teil tertiären und zu einem geringen Teil quaternären Aminogruppen versehenen Polyalken-Matrix sorbiert und nach Abtrennen des beladenen Ionenaustauschers aus der Lösung mit Salpetersäure von diesem wieder eluiert werden.

Durch Drehen des Behälters mittels eines Getriebemotors (17) wird eine gleichmäßige Verteilung der unterschiedlichen großen Kalksteinstücke erreicht. Da zudem die für einen Brennzyklus erforderliche Brenngutmaschine auf zwei Behälter (8, 9) aufgeteilt werden kann, sind die zu bewegenden Gewichte bei kleinen Hüben wesentlich geringer als bei bekannten Beschickungsanlagen.
