Abstract: A procedure for locating the true leakage point in a pipeline (1) carrying a wet medium uses an electrically conductive sensor line (3), laid along the pipeline (1), to which an electrical supply source of a measurement apparatus (10) can be connected. Electrical measurement parameters, which correspond to RL and I, are measured at at least two different times, RL being the parallel circuit of the leakage resistance corresponding to the leakage point and all the other additional leakage resistances, and I being the leakage location corresponding to this value RL. The pairs of values of RL, I thus obtained are plotted as points in a cartesian coordinate system having the axes RL and I. At least one straight line is then determined from these points, whose point of intersection I0 with the I axis of the coordinate system indicates the true leakage location. If there are several points of intersection, averaging takes place, preferably in accordance with statistical viewpoints or using the Gaussian least-squares method. <IMAGE>

Abstract: Le système très efficace de clonage génétique de l'invention est particulièrement utile pour le clonage de copies d'ADN complémentaire d'ARNS messagers eukaryotiques et peut diriger l'orientation d'inserts dans des vecteurs composites plasmides avec de grandes capacités de clonage. Le clivage d'un tel vecteur ADN, par l'enzyme SfiI de restriction par exemple, crée deux extensions 3' différentes non symétriques aux extrémités du vecteur ADN. En utilisant un agent de liaison-amorçage et un adaptateur, l'ADN complémentaire est préparé pour avoir deux extrémités collantes différentes qui peuvent être ligaturées sur celles du vecteur. Lorsque les fragments d'ADN complémentaire et les ADNs sont mélangés, les deux molécules peuvent s'assembler sans auto-circularisation due à la spécificité d'appareillage des bases. Ce système offre (1) une grande efficacité de clonage (107-108 clones/g poly (A)+ ARN), (2) un faible fond (plus de 90 % des clones contiennent des inserts), (3) une insertion directionnelle des fragments d'ADN complémentaire dans les vecteurs, (4) la présence d'un seul insert dans chaque clone, (5) une aptitude à recevoir de longs inserts (jusqu'à 10 kb), (6) un mécanisme de récupération de la partie plasmide d'un génome lambda et (7) un protocole direct pour la préparation d'une librairie.

Title: Condensateur a couche et son procede de fabrication

Abstract: Au moins une partie de chacune des couches protectrices (1, 4a, 4b, 5a, 5b, 6a, 6b, 6c, 7, 8a, 8b) disposées à l'extérieur de la partie (2) produisant une capacitance d'un condensateur à couche, se compose d'une couche mince (10) de sulfure de polyphénylène non orientée. La couche mince (10) de sulfure de polyphénylène non orientée ne rétrécit pas même lorsqu'elle est chauffée lors d'une liaison et d'un soudage thermique, et au contraire absorbe les déformations de l'autre partie de la couche, dues au rétrécissement thermique. Par conséquent, on peut garantir une stabilité de liaison à l'intérieur de la couche protectrice ainsi qu'une stabilité dimensionnelle de cette dernière. Il en résulte que la distance thermique non seulement de la couche protectrice mais également du condensateur peut être améliorée, et il devient possible de simplifier le processus de liaison ainsi que d'éliminer l'emploi d'adhésif. Il est également avantageux pour réduire davantage les tailles de condensateurs à couches.

Abstract: L'invention se rapporte à un film à orientation biaxiale qui est composé de polyéthylène à faible densité linéaire ayant une différence de température entre Tmb et Tma d'au moins 3 °C. Tma représente une température crête principale d'une courbe de fusion, quii est obtenue lors de la mesure du point de fusion au moyen d'un calorimètre à balayage différentiel en maintenant un échantillon à 190 °C pendant 30 minutes, en abaissant la température à 20 °C à une vitesse de 100 °C par minute, puis en élevant la température à une vitesse de 10 °C par minute, Tma étant alors égal à 118 U 5 °C. Tmb représente une température crête principale d'une autre courbe de fusion, qu'on obtient de la même façon en maintenant un échantillon à 190 °C pendant 30 minutes, en abaissant la température à 20 °C à une vitesse de 10 °C par minute, puis en élevant la température à une vitesse de 10 °C par minute. Etant donné qu'une telle résine présente d'excellentes caractéristiques de stabilité à l'étirage, elle peut être étirée avec une faible résistance à la traction tout en restant stable, ce qui permet de produire un film orienté ayant d'excellentes propriétés non seulement d'extensibilité et de rétrécissement mais également de reprise élastique.

Abstract: By using multiple external gears (9,11,12,13,14) and internal gears (10), which are engaged with each other, and multiple radial sealing elements (15-22),and axial sealing elements, a pump or motor, which includes multiple equivalent pumps or motors, is made. Each gear included in thus made gear pump or motor is radially hydraulically counterbalanced, even completely hydro-mechanically counterbalanced, loads on bearings being able to become zero. Axial gaps and radial gaps both have been compensated. The pump or motor can stagelessly vary its output. Accordingly, a gear pump or motor with constant output or stagelessly variable output, as well as a relevant stageless hydraulic speed variator, can be made, which will have lower production cost, higher transmission efficiency and higher power density.

Abstract: To prepare finely divided aluminium nitride by reaction of hydroxides of aluminium with carbon in a molar ratio of (1 : 1.5) to (1 : 2.5), the hydroxides are vigorously ground together with carbon, in particular carbon black, using a non-aqueous grinding liquid. After the non-aqueous grinding liquid has been separated off from the suspension, the millbase obtained is calcined by passing nitrogen through it at 400 to 1000 DEG C. The material obtained is next treated with nitrogen at 1400 to 1700 DEG C for 1 to 100 hours with intensive contact before removing the excess carbon present in the reaction product by heating at 500 to 900 DEG C in contact with oxygen-containing gases. …<??>It is also possible to vigorously grind the hydroxides of aluminium and the carbon each separately, using a non-aqueous grinding liquid, and to mix the suspensions obtained.

Abstract: Adjacent buried contacts (11, 12, 13) formed at the principal surface of a well or substrate region (14) of a semiconductor device, each having a doped contact region (29, 30 31) of one conductivity type and a punch-through prevention region (36, 37, 38) of the opposite conductivity type surrounding the lower portion of the doped contact region are provided. The punch-through prevention region may advantageously be of the same conductivity type as the substrate. By performing an extra implant or other impurity introduction step while the mask to etch the contacts through the dielectric layer remains in place, the procedure to provide punch-through protected buried contacts may be easily integrated into current processes without the need for an extra mask. Such a structure and procedure enables buried contacts to be spaced closely together without over-doping the well region (14) in which source-drain regions (40, 42, 44, 46) are also formed thus avoiding a degradation in device performance.

Abstract: In a guiding frame for electrical conductors, in particular for aircraft, comprising individual tubes connected to one another at predetermined points, free ends of the tubes being connectable to the structure of the aircraft, the invention consists in that the guiding frame (1) comprises tube elements and shaped connecting parts, the shaped connecting parts having connection spigots 11 adhesively inserted into the tube elements, on the outer cylindrical surfaces of which spigots wedge-shaped pockets 20 are arranged, and the tube elements and shaped connecting parts consist of a thermoplastic material such as polyether ether ketone. In this case it is particularly advantageous that not only weight advantages are achieved but also lower production costs, which result inter alia from dispensing with an elaborate pretreatment for adhesion. Furthermore, it is advantageous in this case that the occurrence of arc tracking is reduced. <IMAGE>
