Abstract: A microporous zirconia whose characteristic is that it has pores with a mean diameter of less than 2 nm. The invention also relates to a process for its preparation, characterised in that it consists in performing a thermohydrolysis of a zirconium salt, separating off the precipitate obtained and calcining it and in that it consists in using at least one anion which is more covalent than the hydroxyl anion before the calcination stage. The zirconia of the invention exhibits a thermal stability of its porosity, and this is particularly advantageous for catalytic applications.

Abstract: Un système hydraulique de freinage à anti-enrayage comprend une soupape d'étranglement (8) dans laquelle est inséré un étranglement dans la conduite du frein en cas de réglage du glissement de freinage. Les pompes (12, 13) refoulent le milieu hydraulique à travers cet étranglement jusqu'aux freins des roues. Le réglage de la pression dans les freins des roues se fait uniquement au moyen d'une soupape d'émission (11) dont la section transversale d'ouverture est sélectionnée de telle sorte que la quantité de milieu hydraulique évacuée par la soupape d'émission (11) soit supérieure à la quantité de milieu hydraulique refoulée par les pompes (12, 13) jusqu'aux freins des roues à travers l'étranglement. Lorsque la soupape d'émission (11) est ouverte, par conséquent, la pression diminue, alors que lorsque la soupape (11) est fermée, la pression augmente dans les freins. L'invention concerne différentes possibilités de commande de la soupape d'étranglement (8).

Abstract: The invention relates to a closure cap (5) having a dispensing opening (6) for containers with flexible walls, which can be pressed together by hand for the dispensing of spray product which is in connection with the dispensing opening (6) by means of a dip tube (7). Upstream of the dispensing opening (6) is an outlet valve (8), which is open when there is positive pressure in the container, whereas an air-admitting opening (9) is assigned an air-admitting valve (10), which is open when there is negative pressure in the container. By virtue of the outlet valve (8) upstream of the dispensing opening (6), the readmission of air to the container and consequently the risk of sucking in through the dispensing opening (6) substances contaminating the container content is prevented. Maintaining the quality of the spray product in the container is ensured by virtue of the air-admitting opening (9), separate from the dispensing opening (6), and the air-admitting valve (10), which opens only when there is negative pressure in the container.

Abstract: The impellers have a plurality of fluidfoil blades (12,14,16) and have camber and twist. The geometric pitch or blade angle increases from the tip (24) of the blade towards their axis of rotation in a manner to provide an over pitched condition so that the pitch ratio of the blades at 40% of the blade radius from the axis is greater than the pitch ratio at the tip. The blades are preferably smoothly tapered and increased in width from the tip towards the axis. The impeller blades are mounted on a hub (18) connected to a drive shaft. The blades may decrease in width where they connect to the hub. The pitch angle at the tip is in the range of 18 DEG  to 30 DEG (preferably about 20 DEG ). The angle at the tip of two diametrically disposed blades of a four blade impeller may have a different blade angle at the tip than the other pair of blades. A pair of impellers may be used. These impellers may be of different diameter and disposed in close proximity so that they are in dependent relationship (preferably spaced apart by less than the diameter of the larger impeller). <IMAGE>

Abstract: A membrane gas separation apparatus, typically for separating air, includes a gas separation all 14 containing an array of membranes in the form of hollow fibres 18. The cell 14 has a first gas port 16 and a second gas port 20. Flow of gas to and from the ports 16 and 20 is controlled by a four-port, two-position valve 12. In one position, the valve 12 admits incoming air to the port 16 and allows product nitrogen to flow out of the port 20. In the other position the roles of the ports 16 and 20 are reversed and hence the direction of flow of the gas is reversed. During prolonged operation, there is a tendency for contaminants to affect disproportionately the feed gas inlet and of the membrane fibres 18. By periodically changing the position of the valve 12, different ends of the membrane fibres 18 are presented to the feed gas, and thus the operating life of the membranes 18 is lengthened. <IMAGE>

Abstract: Controlling turbulence in a medium, caused by injection of energy into the medium at relatively large scale with consequent dissipation of energy at relatively small scale, is achieved by introducing into the medium a broad spectrum stochastic external disturbance. In particular, the method is used to enhance propulsion of a ship, submarine, or aircraft, or flow through a pipe. The disturbance is, in particular, introduced as a substantially white noise signal into a boundary layer so as to disrupt coherence of the flow field in the inertial range.

Abstract: The present invention is directed to a process for sulfating unsaturated alcohols using inexpensive reagents and mild reaction conditions. The process comprises reacting an unsaturated alcohol of the formula R-OH, wherein R is a C8-C22 alkenyl group, with an ether sulfate of the formula R1(OCH2CH2)nOSO3M, wherein R1 is a C¿1?-C18 hydrocarbyl group, n is an integer from 1 to 10, and M is an alkali metal, to form an unsaturated sulfate; said reaction being carried out in the presence of a catalytically effective amount of an acid catalyst. The mole ratio of unsaturated alcohol reactant to ether sulfate ranges from about 0.5:1 to about 2:1. In this process the sulfation occurs primarily at the hydroxyl goup of the unsaturated alcohol, with minimal sulfation at the olefinic moiety of said alcohol.
