Patent EP-0333716-A1 (EP)
Inventor: OYER MICHAEL W
IPC: B64D45/00
Filed: 1987-09-24
Abstract: Un système de sécurité pour aéronef comprend une unité de commande centrale (10), plusieurs contrôleurs (14) de groupement de signaux disposés à distance et plusieurs détecteurs d'intrusion (16) associés à chaque contrôleur de groupement et commandés par lui. Un bus à deux fils (12) transporte l'énergie provenant de l'unité de commande centrale en vue de faire fonctionner chacun des contrôleurs de groupement ainsi que les détecteurs et transporte des signaux de données dans les deux directions entre l'unité de commande centrale et les contrôleurs de groupement. Le bus à deux fils permet de réduire le poids et le coût de l'installation. Ledit système comprend un mode de calibrage initial, dans lequel les informations à caractères provenant des détecteurs et les paramètres des détecteurs sont envoyés en provenance de l'unité de commande centrale vers chaque contrôleur de groupement. L'intensité des signaux provenant de chaque détecteur est ensuite mesurée et stockée dans l'unité de commande centrale. Durant cette dernière opération, les intensités des signaux de détecteur sont mesurées et comparées aux valeurs initiales. Si une anomalie est détectée, une correction appropriée est entreprise. Une correction consiste à faire varier l'énergie transmise jusqu'au moment où l'intensité des signaux du détecteur se situe dans une plage prescrite.

Abstract: The present invention relates to a method for purifying calcium nitrate melt/solution separated from the mixture obtained by dissolution of rock phosphate with nitric acid. The melt contains fluorine and phosphorus as main contamin­ants. The mol-ratio phosphorus/fluorine in the crude calcium nitrate melt/solution is adjusted to 3.5>P/F>0.3, possibly by extra addition of a phosphorus compound, and the mixture is then neutralized by ammonia to pH = 5-6. The precipitate thereby formed is removed while the filtrate, which is a purified nitrate of lime melt, is evaporated and further processed. The purification can be carried out in two stages, with a P/F-ratio in the first stage of 0.3-3 and 1-3.5 in the second stage. Phosphoric acid or a phosphoric acid containing solution is used as phosphorus compound.

Abstract: The invention relates to an automatic door or window installation with at least one driven sliding wing. It serves as a replacement installation for exchanging a corresponding old installation to be replaced in a carrier structure anchored in place. To exchange an old installation of this type, work involving a high outlay is necessary at the present time, so that the new drive can be inserted into the carrier structure installed in place. The invention makes a simple and cost-effective conversion possible, in that the replacement installation is fastened in the slide rail of the old installation. This means that, for the conversion, the old installation is firstly removed from the fixed carrier structure, the carrier structure 6 together with the slide rail 27 of the old installation remaining installed in place. The replacement installation is then fastened to the slide rail 27, especially by hooking and clamping by the use of a separate coupling adaptor 20 which has a fastening profile 31 engaging into the slide rail 27. <IMAGE>
