Abstract: Selon un procédé de détermination de l'impédance en court-circuit d'une installation d'alimentation en énergie électrique à contrôler, on calcule les coefficients d'une matrice de système Xi ou d'une matrice de système Xu1 d'un modèle présélectionné d'installation d'alimentation en énergie électrique, en tenant compte de la fréquence du réseau de l'installation à contrôler et de la succession présélectionnée dans le temps de valeurs d'analyse d'une valeur de mesure proportionnelle au courant dans l'installation et d'une valeur de mesure proportionnelle à la tension dans l'installation. A partir des vecteurs présélectionnés de paramètres betai(O) ou betau1(O), on détermine les vecteurs des paramètres sur la base des valeurs respectives d'analyse des valeurs de mesure et de la matrice de système respective Xi ou Xu1 par évaluation récursive, avec un vecteur prédéterminé d'erreur le plus réduit possible, puis on en déduit l'impédance en court-circuit. Afin d'éviter lors de la détermination de l'impédance en court-circuit des erreurs provoquées par l'influence d'un arc électrique pendant un court-circuit, la matrice de système Xu1 est calculée selon ce procédé en détectant et en tenant compte du signe de chaque valeur d'analyse (yi(k)) de la valeur de mesure (i(tk)); un élément supplémentaire de prise en compte d'un arc électrique en cas de court-circuit est en outre utilisé lors du calcul du vecteur de paramètre betau1.

Filed: 1991-10-31
Abstract: On décrit une enveloppe en papier (1) pour cigarette à bout filtre destinée à la préparation des cigarettes par le consommateur lui-même. L'enveloppe en papier (1) pour cigarette à bout filtre présente une section filtre (2) et une section enveloppe (3) proprement dite reliée à la première et présentant une extrémité ouverte éloignée de la section filtre où il est possible d'introduire un produit pouvant être fumé, en l'occurence une quantité de tabac (5). Selon l'idée de base de l'invention, l'ouverture (4) est coupée dans un plan incliné (S) par rapport au plan perpendiculaire à l'axe longitudinal de l'enveloppe, ce qui facilite l'introduction des produits pouvant être fumés. La forme raccourcie de la section enveloppe donne un filtre à emboîter (10) qui peut ensuite être monté sur des cigarettes sans filtre (15). Ce type de filtre à emboîter peut en outre être monté sur des cigarettes se présentant déjà sous la forme de cigarettes à bout filtre (20), un espacement axial (24) étant prévu de préférence entre les deux bouts filtre, ce qui améliore sensiblement le filtrage des substances nocives. Dans le cadre de l'invention, ce principe du double filtrage peut également être prévu initialement au stade de la fabrication sur des cigarettes à bout filtre pour produire des cigarettes à double filtre.

Abstract: Described is a method for preparing a catalyst support material, comprising commercially available silica, by utilizing a fluorine-containing acid. The novel method is utilized to produce a novel composition that has unique physical properties different from those of typical commercially available silica materials. The novel support material has significantly improved values for crush strength and as good or better pore volume than comparable catalyst support materials. Due to these improved physical properties, the novel composition is more durable and longer lived. Furthermore, the greater pore volume of the novel composition provides for enhanced catalytic activity when the formed silica material is utilized as a catalyst support.

Abstract: A radio frequency amplifier comprises a differential amplifier having a pair of differential first and second transistors (1,2) and a first and a second load resistor (4,5); an emitter grounded amplifier having a third transistor (6) and a third load resistor (7); and a reference voltage generator having a constant-current source formed by a fourth transistor (8) and a fourth load resistor (9). The emitter grounded amplifier receives a high frequency input signal and outputs a single signal output. One input node of the differential amplifier receives the output from the emitter grounded amplifier and the other input node receives a reference voltage from the reference voltage generator. The third and fourth transistors (6,8) form a current-mirror circuit. The DC bias voltages of the two input nodes of the differential amplifier are set to have the same value by an appropriate selection of the ratio between the currents (I6,I8) flowing in the third and fourth transistors (6,8) and also the ratio between the resistance values (R7,R9) of the third and fourth load resistors (7,9). This arrangement enables to divide a high frequency input signal into a single signal output and differential signal outputs.
