Abstract: A liquid-plug-creating device includes a collection tank or basin into which liquid flows such as the outflow from sanitary appliances. From the outlet at the bottom of the tank a riser extends upwardly at an acute angle to the horizontal. At the opposite end from the tank outlet, the riser terminates in a bend which reverses the direction of flow through the riser into a downwardly extending vertical pipe. A U-shaped piece of pipe with a horizontal outlet is connected to the lower end of the vertical pipe and provides a special form of trap. When the tank and the riser are completely filled with liquid, any additional liquid added exceeding a minimum flow, causes a liquid seal to be formed in the piece of pipe at the lower end of the vertical pipe. The excess flow creates a vacuum in the vertical pipe which sucks the liquid through the riser out of the tank in the manner of a siphon. The liquid immerges from the device in the form of continuous plugs with high kinetic energy content. The device permits the use of small-diameter pipes in house drainage systems while assuring the required self-cleansing effect, even if water-conserving flush toilets are connected to the device. Other fields of application of the device are irrigation and the metering of liquids in batches.

Abstract: In a CCD scanning arrangement, first and second CCD arrays (10, 11) are used to look at spaced apart reading lines, the sensor elements of the two arrays being staggered longitudinally relative to one another by half a pitch of the sensor elements. First and second stylus arrays (14,15) spaced apart by the same distance as the reading lines are connected respectively (via appropriate electronics) to the sensor elements of the first and second CCD arrays (10,11). Thus, in use, as the first and second reading lines in turn scan a document (2), the first and second stylus arrays (14, 15) create a copy. The second line fills in the gaps between the styli of the first writing line, thereby doubling the lines per cm across the copy.

Abstract: Un manchon d'isolation rempli de gaz pour haute tension possede un boitier externe en porcelaine contre les intemperies (10) qui possede un conducteur central allonge (13) s'etendant au travers. L'interieur du boitier en porcelaine est rempli d'hexafluorure de soufre gazeux. L'interieur de la chemise est au moins partiellement rempli avec un module (15, 16) qui reduit le volume libre de gaz et peut etre un module forme d'un materiau fibreux enroule ou une mousse contenant un gaz dielectrique, rigide ou elastique. Les deux reduisent le volume de gaz libre d'hexafluorure de soufre sous pression dans le boitier en porcelaine reduisant ainsi les risques potentiels d'explosion si le boitier venait a casser. Le corps de mousse peut etre un materiau polymere quelconque dans lequel on envoie un gaz quelconque approprie y compris l'hexafluorure de soufre ou freon. La mousse est une mousse a cellules ouvertes et cellules fermees, et dans un mode de realisation les surfaces exterieures d'une mousse a cellule ouverte sont obturees avec un produit obturateur pour empecher le gaz dielectrique de s'echapper. Le module peut contenir des couches d'etagement de capacite (17-22) de maniere a etager ou graduer la contrainte dielectrique sur la surface exterieur du manchon, permettant ainsi d'utiliser un manchon aux dimensions reduites pour le meme travail electrique. Le volume total du manchon, ou l'espace libre entourant le module, peut etre rempli de spheres creuses chargees d'un gaz dielectrique, ou peuvent etre remplis avec des tamis moleculaires charges de gaz. Des procedes utilisant de l'energie micro-ondes sont decrits pour faire mousser le plastique et pour la fabrication des modules.

Abstract: In a wire or band electrode type electric discharge machine an electric spark is generated between the wire or band electrode (2) and a workpiece (12) to machine that workpiece (12). The electrode (2) is fed longitudinally of itself to provide a fresh supply thereof. 
     For automatically restoring operation when the electrode (2) breaks; the machine has a damping mechanism (8) which immediately clamps the broken electrode (2) on the electrode supply side of the workpiece (12) to prevent the electrode (2) falling under its own weight. An electrode feed mechanism (9) is then actuated, first to draw back the broken electrode (2) from the workpiece (12) on the supply side then to guide the end of the broken electrode (12) into a slot or hole (21) machined in the workpiece (12) until the end emerges from the other side of the workpiece (12). An electrode pull-up mechanism (13) grips the emergent end and pulls up the electrode (2) after release by the clamping mechanism (8).

Abstract: Known catalysts for producing a diallyl ester of an aromatic dicarboxylic acid, particularly a diallyl ester of an aromatic symmetrical dicarboxylic acid, by heating an ester of an aromatic dicarboxylic acid with an allyl alcohol to effect ester exchange, suffer from low catalytic activity and a tendency to cause formation of by-products and colouration of the product. These problems can be overcome by effecting reaction in the presence of, as catalysts, both (A) at least one organic tin compound of the formula (I)
     wherein R 1  and R 2  independently represent alkyl of 1 to 8 carbon atoms or phenyl, and X represents two halogen atoms or an oxygen atom, and (B) at least one substance which is an element or compound of an element belonging to group IIa, IIb, IIIa, IVa, IVb or VIII of the periodic table of elements, other than organic tin compounds represented by the general formula (I).

Abstract: Suivant l'invention, un axe d'aimantation facile est créé suivant l'axe longitudinal d'un fil magnétique (1) à forte teneur en cobalt par courbure de ce fil ensuite placé dans un tube creux non magnétique (2) à l'intérieur duquel les deux extrémités du fil viennent en appui. Ce tube est placé suivant l'axe d'une bobine de détection (3). L'application d'un champ magnétique alternativement dans un sens et dans l'autre suivant l'axe longitudinal de l'ensemble crée une variation de flux due au basculement de l'aimantation suivant l'axe facile, les impulsions détectées ayant une grande amplitude et un faible temps de montée. Un tel capteur magnétique est applicable, notamment pour des capteurs de proximité d'éléments en translation ou en rotation, par exemple pour des moteurs.

Abstract: Die Erfindung betrifft ein Verfahren zur Entfernung von Ammoniumnitrat (AN) aus wäßrigen Lösungen. Die bekannten Verfahren arbeiten meist mit der Abtrennung von NH3, wobei dieses zum Teil durch Temperaturerhöhung aus der Lösung ausgetrieben werden muß, oder durch thermische Sprühzersetzung der AN enthaltenden Lösungen oder durch Behandlung der Lösung mit konzentrierter Salpetersäure in Anwesenheit von Chloriden. Hierbei werden meist Temperaturen über 100°C erforderlich, die benötigte Vorrichtung ist aufwendig im Hinblick auf Material- und Raumbedarf und es bilden sich unerwünschte nitrose Gase. Die Erfindung vermeidet diese Nachteile dadurch, daß der das AN enthaltenden, wäßrigen Lösung mindestens eine Stickstoff-Sauerstoff-Verbindung der Form NOx und/oder N2O2x, wobei x = 1 oder 2 bedeutet, in gasförmigem oder flüssigem Zustand oder als in einer wäßrigen Lösung vorliegendes Ion bei einer Temperatur oberhalb Raumtemperatur, jedoch unterhalb des Siedepunktes der AN enthaltenden Lösung bei Normaldruck zugeführt wird. Mit der Erfindung kann das AN bei einer Temperatur unter 100°C zersetzt werden. Als Zersetzungsprodukte entstehen praktisch nur N2 und etwas N2O.
