Abstract: The protective device possesses elements having an at least partially water-permeable shell made of nonwoven polyester (1) and super-absorbent material disposed therein. The shell forms an expandable, closed interior space. It is resistant to tearing even when wet. When dry, the elements are of light weight and small volume. As soon as they come into contact with water, the super-absorbent material absorbs a considerable amount of water and the elements expand. Consequently, they can be employed for the absorption of water while at the same time forming barriers. Thanks to their low dry weight, they can be transported and deployed rapidly and in large numbers. <IMAGE>

Abstract: The method for manufacturing a flexible material container for transporting and storing products in bulk includes the operations of forming and stitching the container which is to be made, from a flat or tubular rec­tangular sheet (1) of suitable material (fabric and/or plastic.) As of this sheet, by means of a series of folds, a square or rectangular bottom is obtained for the respective container (C1), in terms of the distance between the stitching reference points; this all without effecting any cut upon the corresponding sheet. The bottom may or may not be affected by an intermediateseam, while the container may or may not be affected by side seams. 
     A top feed opening is shaped in the container and the mouth can be open all along the container, or there may be access only through the end areas of the sides, upon the top edge forming a suspension handle being closed.

Abstract: An improved method of presulfiding a hydro­treating catalyst which minimizes sulfur stripping upon start-up of a hydrotreating reactor utilizing such a catalyst. The method comprises the steps of contacting a hydrotreating catalyst with elemental sulfur at a temperature below the melting point of sulfur, thereby forming a sulfur-catalyst mixture, and heating the sulfur-catalyst mixture to a temperature above the melt­ing point of sulfur. Preferably, the sulfur-catalyst mixture is first mixed with a high boiling oil or a hydrocarbon solvent to form a prewet mixture prior to heating at a temperature above the melting point of sulfur.

Abstract: Each of a row of thin film magnetic transducers (12) formed on a substrate, comprises a magnetoresistive (MR) element, and the row is supported on a holder (18) which has an elongate H-shaped slot near one edge to form a beam member upon which the row is mounted. The beam member is capable of being deflected in a substantially quadratic curvature when subjected to pressure from a pressure transducer (22) at the middle of the beam member. The resistance of each of the MR elements is measured (by 28, 30) during lapping, and control signals are generated (by controller 32) to control the pressure transducers to control lapping with proper BALANCE and BOW and to terminate lapping when the desired MR element height is reached.

Abstract: In a flow cylinder with gears mounted in a freely rotatable manner in a measuring chamber, the teeth are counted. Since, on account of the high internal pressure, tight seals would be necessary for a gear shaft directed to the outside, which seals in turn exert high friction forces on the shaft, it is known to make a magnetic pick-up. To this end, a magnetic field conductor is required which normally consists of two magnetically conductive rods. Since these rods, on the side of the gears, have to be at a distance apart determined by the size of the gears, but on the other side have to be at a distance apart determined by the size of a field-plate differential sensor, it has already been proposed to insert pins at an oblique angle. But this involves disadvantages in manufacture. According to the present invention, a plate (12a) of magnetically conductive material is used in which a sleeve (12b) of magnetically non-conductive material sits in which there is a pin (12c) of magnetically conductive material. The wall of the sleeve is thicker at the end facing the gear than at the end facing the field-plate differential sensor. <IMAGE>

Abstract: Dans un moteur à combustion interne à deux temps (2) un passage-réservoir de flux air-carburant (52) est disposé le long du pont d'échappement (34) et entre le piston (4) et la paroi interne (36) du cylindre, pour permettre la lubrification du pont d'échappement (34). Le piston (4) comporte une surface plate (50) usinée sur sa paroi (38) et destinée à former un passage-réservoir d'écoulement s'étendant axialement, qui est fermé à son extrémité supérieure par les segments (40) du piston et à son extrémité inférieure par une partie inférieure (60) de la paroi (38) du piston qui n'est pas usinée et qui se trouve à proximité adjacente de la paroi interne (36) du cylindre. Lorsque le piston (4) se trouve dans sa course d'explosion, la pression du carter moteur force le mélange air-carburant à passer à travers des trous (56, 58) ménagés dans la paroi (38) du piston au niveau de la surface plate (50) et à pénétrer dans le passage-réservoir d'écoulement (52). Si le pont d'échappement (34) s'échauffe et en se dilatant pénètre dans le cylindre (6), le piston (4) n'exercera aucun frottement sur lui.

Abstract: Un système de transmission d'entraînement d'un véhicule à moteur comprend un moteur à combustion (8), une boîte de vitesse (10) et un embrayage (20) à commande électronique. Le papillon des gaz (84) du moteur est actionné par un moteur électrique (92) commandé par la commande électronique (48) ordinairement en réponse à des signaux de demande au papillon des gaz. L'actionnement manuel du levier (16) de changement de vitesse provoque le désenclenchement automatique de l'embrayage. Lorsque l'on passe une nouvelle vitesse l'embrayage (20) se réenclenche automatiquement. Lorsque l'on passe une vitesse supérieure, l'embrayage (20) se désenclenche automatiquement pour abaisser (102) sa capacité de transmission de couple (C) d'un maximum (C1) à une valeur nulle. A mesure que le changement de vitesse progresse, la nouvelle vitesse commence à s'enclencher avec pour résultat de faire chuter la vitesse (B) de l'arbre d'entrée de la boîte de vitesse (14) et du disque (32) récepteur de l'embrayage, à une valeur (Sn). Pendant le déroulement de ce processus, la commande (48) prend entièrement le contrôle du papillon et le ferme. Le désenclenchement de l'embrayage et la fermeture du papillon provoquent la décélération (114) de la vitesse (A) du moteur. Lorsqu'une nouvelle vitesse est totalement engagée au moment (t4), la commande (48) provoque le réenclenchement de l'embrayage à un premier régime relativement élévé (118) à partir d'une valeur nulle jusqu'à une capacité (Ct) de transmission de couple recherchée prédéterminée, puis à un régime plus bas (124).

Abstract: The invention relates to a microfiltration process, in particular for separating beer from a materials flow which is purged during the fermentation process and which takes along the excess yeast produced during the fermentation, wherein the materials flow containing haze substances to be filtered is passed under pressure through at least one microfiltration module with porous membranes carrying a tangential flow and a filtrate is taken off. According to the invention, the materials flow to be filtered is continuously fed to a circulated retentate flow, and a concentrate flow having a substantially constant concentration of haze substances is taken off from the retentate flow. The flow velocity and the flow pressure drop of the retentate flow are measured and the concentration of haze substances in the retentate flow is determined from the measured data according to a function F (v,  DELTA p) which is characteristic of the apparatus and which contains the flow velocity (v) and the flow pressure drop ( DELTA p) as variables. The concentrate flow rate is controlled in accordance with the difference in the concentration of haze substances, resulting from a comparison of actual and set values.
