Abstract: Une tuyère de poussée pour avions munis de moteurs à réaction, notamment pour commander le vecteur de poussée latérale, comprend au moins deux volets (8, 12) actionnés par des organes d'ajustement similaires à des leviers montés à leur extrémité en amont du courant. Les volets sont agencés entre des parois (22, 23) essentiellement parallèles à l'axe de la tuyère d'un logement rectangulaire de la tuyère, de manière à pivoter simultanément autour d'axes de rotation transversaux à l'axe (20) de la tuyère avec des angles de rotation différents. On obtient ainsi avec un profil uniformément convergent de la tuyère une section transversale entre les volets (8, 12) qui est plus étroite du côté sortie. La première extrémité des organes d'ajustement (28, 29) similaires à des leviers enclenche les extrémités des volets en aval du courant et leurs deuxièmes extrémités sont mutuellement couplées de manière mobile de façon à se déplacer dans une voie de guidage (30) courbée de manière à produire des angles de rotation différents toujours pour chaque volet. Une ou plusieurs sections transversales plus étroites peuvent être maintenues constantes ou peuvent être modifiées en fonction de l'angle de déviation du jet.

Abstract: Selon un procédé électrochimique de quantification de populations de bactéries entières vivantes, on filtre les bactéries, puis on utilise le filtrat en association avec une unité de mesure électrochimique (15) afin de déterminer la densité de comptage des bactéries. Selon un procédé d'écoulement, on utilise la moyenne des signaux pendant la période prédéterminée de durée du test, en conjonction avec une constante, afin de quantifier la population de bactéries. Selon un procédé de déviation, on transmet un réactif par une ligne de déviation (18) jusqu'à l'unité de mesure électrochimique (15) et on soustrait le signal obtenu du signal généré par le filtrat, une constante étant utilisée pour mettre en corrélation le reste ainsi obtenu avec la numération des bactéries. Selon un procédé à concentrations variables, on utilise une concentration variable de bactéries dans un même fluide afin de quantifier des populations de bactéries. Selon un procédé à échantillon récupéré, ou soumet le filtrat à un deuxième test après un intervalle de temps prédéterminé, ce qui permet de compenser la présence éventuelle de contaminants.

Filed: 1991-02-07
Abstract: The previously known process for manufacturing an ultrasonic transducer with a piezoelectric transducer element which is connected to an acoustic coupling layer which is composed, as a single uniform body, of oscillatory elastomer, has several disadvantages. Thus, for example the quality of the coupling layer itself cannot be tested but rather only the finished transducer so that if the coupling layer has inadequate properties in the case of a negative test result the entire transducer must be rejected. In addition, a complex device has hitherto been used for manufacture. The object of simplifying and improving the abovementioned process for manufacturing ultrasonic transducers whilst avoiding the stated disadvantages is achieved in that initially a preform made of elastomer (2) with centring contours (4) is produced and in a further process step the transducer element (1) is inserted into the elastomer body (2) accompanied by centring by means of the centring contours (4) and is connected to the coupling layer (3) of said body. <IMAGE>

Abstract: A device for shaping human hair in which the possibly pre-dampened hair is wound in sections onto rollers (10) and a liquid or consistent, i.e. a creme or gel perming preparation is applied to the rollers and allowed to act on the hair rollers (10) for a preset period with the supply of heat energy. The perming agent is then washed out and, if necessary after additional treatment with a liquid fixer which is subsequently rinsed off, the rollers (10) are removed from the hair. The rollers (10) are heated within a preset temperature range after the hair sections have been wound on and the perming preparation has been applied, by the brief supply of energy. The heat energy stored in the rollers (10) is then transferred from the rollers (10) to the wound hair which has been treated with the perming preparation. <IMAGE>

Abstract: An acoustic fuel (or other liquid, powder or solid) sensor (50), is disclosed. The sensor measures the volume of fuel in a container (62), of known size. The air (64), within the container is excited by an acoustic transducer (56). The transducer is driven by a frequency scanning source, and the frequency response of the air cavity within the container is monitored. This frequency response is then processed to determine the volume of air in the container, and the fuel volume is determined to be the total container volume less the air volume. In one embodiment, a tube (52), connects the transducer through an orifice (54), to the air volume, and the frequency response is observed to determine the resonant frequency of the air cavity within the container. The volume of the air cavity is then determined from the resonant frequency. The volume of the fuel is then determined from the tank volume minus the volume of the air cavity.

Abstract: A flexible clay liner (12) in roll form for use on steep slopes. The liner includes a layer of geotextiles (22,24). The geotextiles (22,24) are stitched together in rows (14) of stitches (17) which extend along the length of the liner (12).
