Title: Procede et dispositif permettant de limiter la formation de tartre et/ou la corrosion dans des systemes d'acheminement de liquides
Inventor: MIECZNIK BERT
IPC: B01J39/02

Granted: 2009-01-27
Abstract: La présente invention concerne un procédé et un dispositif permettant de limiter la formation de tartre et/ou la corrosion dans des systèmes servant à acheminer des liquides ou étant en contact avec des liquides. Selon l'invention, ceci est obtenu sans réduire la teneur en agents de dureté du liquide dans son ensemble, sans remplacer les agents de dureté présents dans le liquide par d'autres cations tels que les ions hydronium, sodium ou potassium, et sans avoir à ajouter des produits chimiques inhibant le liquide contre la formation de tartre, tels que les phosphates. A cet effet, la formation de tartre est limitée grâce à un décalage ciblé de la répartition molaire des agents de dureté, en particulier des fractions de répartition des agents de dureté individuels magnésium d'une part, et calcium, strontium et baryum d'autre part. Selon le procédé de l'invention, les fractions des agents de duretés calcium, strontium et baryum présents dans le liquide sont remplacées par des fractions de l'agent de dureté magnésium. Ledit procédé permet, en plus d'une réduction efficace de la formation de tartre, d'inhiber les phénomènes de corrosion qui se déroulent dans les systèmes servant à acheminer des liquides ou étant en contact avec des liquides, et ainsi de réduire l'ampleur de ces phénomènes.

Abstract: A VPN device clustering system connects two or more VPN devices on one side of a virtual private network to a similarly clustered system of two or more VPN  devices on the other side of a virtual private network. The VPN device clustering system typically includes a plurality of clustering units for redundancy that avoids difficulties that arise with a single point of failure.  For example two clustering units may be used in an active-passive high-availability configuration. A VPN device cluster creator creates or configures a VPN device cluster. To create a VPN device cluster, an administrator assigns to the cluster a logical Internet protocol (IP) address IPvpn and specifies VPN devices that are members of the cluster.

Abstract: Video encoding and decoding processes provide compression and decompression of digitized video signals representing display motion in video sequences of multiple image frames. The encoder process utilizes object- or feature-based video compression to improve the accuracy and versatility of encoding interframe motion and interframe image features. Video information is compressed relative to objects or features of arbitrary configurations, rather than fixed, regular arrays of pixels as in conventional video compression methods. This reduces the error components and thereby improves the compression efficiency and accuracy. The decoder process decompresses the encoded video information to reconstruct the objects or features of arbitrary configurations.

Abstract: A vehicle article carrier adapted for use with outer body surfaces of a vehicle that are curved or non-parallel to one another. The article carrier includes a pair of non-linear slats that are secured in spaced apart relation to one another on the outer body surfaces. A crass bar supporting assembly has a pair of connecting members that support a cross bar at its outermost ends. The connecting members are secured to slider members, and the slider members are adapted to be secured to the slats. The connecting members are secured to the outermost ends of the cross bar and each have bores that enable the outermost ends to be gradually received therewithin as the cross bar is moved along portions of the slats where the distance between the slats decreases; thus effectively shortening the cross bar. Conversely, this coupling enables the length of the cross bar to be effectively lengthened to accommodate increases in the distance between the slats. Each connecting member further includes a slider having a curved face portion which couples to an associated one of the slats and which further helps to prevent jamming of the cross bar as it is moved along the curved or non-parallel slats.

Title: Turbomolecular pump
Inventor: BLUMENTHAL ROLAND
IPC: F04D19/04
Filed: 2002-03-15
Granted: 2010-08-03
Abstract: A turbomolecular pump (10) comprises a stator, a pump rotor, a motor (28) for driving the pump rotor and a control device (42). The control device (42) controls the motor output as to prevent the motor output from exceeding a permissible motor maximum output. Stator-side temperature sensors (32-38), which are provided for measuring the stator temperature, are arranged on the turbomolecular pump (10). The control device (42) comprises a maximum output determining device (50), that establishes the permissible motor maximum output according to the measured stator temperature. The permissible motor maximum output is thus not set to a constant value, but is always determined according to the stator temperature. This results in the power of the motor being fully exploited as long as the measured stator temperature is less than a maximum value.
