Title: Procede de synthese de donneurs d'oligosaccharide ayant subi une sialylation
Inventor: MEHTA SEEMA
IPC: C07H15/203
Filed: 2000-12-08
Abstract: Cette invention a trait à un procédé de synthèse de thioglycosides aryliques comprenant un reste sialylé de β-D-galactose. Le procédé consiste à préparer par synthèse chimique un thioglycoside arylique non sialylé et à lui faire subir une sialylation à l'aide d'un acide sialique en présence d'une syaliltransférase. On dérive ensuite le thioglycoside arylique sialylé au moyen de techniques classiques afin d'obtenir un dérivé pouvant faire office de donneur lors de synthèses chimiques d'oligosaccharides sialylés. Il est possible, en raison de la réduction du nombre d'opérations chimiques et de purification, de préparer avec un rendement élevé ces thioglycosides aryliques sialylés dérivés. Ces derniers se révèlent des plus utiles comme motifs structuraux aux fins de la synthèse d'oligosaccharides sialylés biologiquement actifs.

Title: Toughened polyamide compositions having improved properties
Inventor: BAGHAII PARVIZ
IPC: C08G69/48
Filed: 1989-12-20
Abstract: ABSTRACT           Toughened polyamide compositions are produced by melt blending a polyamide component and a partially crosslinked elastomeric modifier component containing reactive functionalities.  Generally a multiple phase composition is formed wherein the polyamide constitutes a continuous phase and the elastomeric modifier component constitutes a discontinuous phase having a particle size of at least 1.3 or 1.5 microns and preferably at least 5.0 microns.  The discontinuous elastomeric modifier component is made by adding reactive functionalities to an existing elastomer polymer and partially or semi-crosslinking the same in the presence of free radical initiators such that at least 10 percent gel exists.  The amount of the elastomeric modifier component is generally from about 1 to about 85 percent by weight.  The poly-amide compositions have a wide range of improved proper-ties such as good low temperature (e.g., minus 40°C) impact resistance and good high temperature heat deflec-tion (e.g., 65°C).

Title: Control for flexible probe
Inventor: BRUNS ROBERT W
IPC: H01Q13/02
Filed: 1990-01-24
Abstract: PATENT                    ABSTRACT         An electrically-conductive flexible probe is mounted within a wave guide that receives radio-frequency electromagnetic radiation.  A leading portion of the probe has an orientation that is adjustable between two positions that are angularly displaced with respect to each other by 90°.  A permanent bar magnet is connected to the leading portion of probe, and an electromagnet is mounted adjacent to the bar magnet so as to be capable of being magnetically coupled to the bar magnet.  The electromagnet, is electrically controllable so as to control the magnetic coupling between the bar magnet and the electromagnet, move the bar magnet selectively to one of the two angular positions, and thereby correspondingly move the leading portion of the probe and cause the wave guide to transmit radio-frequency electromagnetic radiation having a selected one of two polarizations in planes that are mutually orthogonal with respect to each other and reflect radio frequency electromagnetic radiation having the other polarization.

Abstract: A hydraulic  rotary  actuating  apparatus  comprises  a  housing  (1),  a stepped piston (2) and a shaft (3).  With the aid of two sets of teeth (5, 8) axial displacement of the piston  (2)  is converted  to rotary motion of the shaft (3).  A first radial bearing (17) is disposed near where the shaft leaves the housing.   A second radial bearing (22)  is formed between the shaft (3) and piston (2).  The piston (2) is in turn supported at the housing (1) by way of a third radial bearing (26) and a fourth radial bearing (30).   This permits rotary actuation with a minimum loss of torque and consequently at a high torque.

Abstract: Packages for stacks of folded paper tissues (10) consist of very thin plastic films. To facilitate the usage, recently tear-off aids are provided, in particular in the region of a front wall (11) of the cuboid package. For opening and reclosing the package, a tear-off tab (22) is defined by perforation lines (23, 24, 25) in the region of the front wall (11), which tear-off tab can be opened and closed again with the aid of a covering adhesive tab (37). 
<??>To increase the serviceability of the film package, the tear-off tab (22), bounded by lateral perforations (23, 24) is narrower than the front wall (11), in particular in such a way that a cutout (32) is formed which is sufficient for the removal of a paper tissue (10). Adjoining the perforations of the tear-off tab (22) in the region of one front edge (26) is a transverse perforation (28, 29) which is opened by lifting the front wall of the package. By this means, a removal opening (21) is produced which extends over the full width. 
<??>In this embodiment of the tear-off aid, a design of the package is advantageous, in which folding flaps of the end wall 16 are separated from one another by punch cuts (43, 44) and can thus be folded in a rectangular shape.

Abstract: An exhaust flap for use in the exhaust section of an aircraft gas turbine engine is built with increased service life and ease of replacement.  The exhaust flap includes convergent nozzle flaps, divergent nozzle flaps, convergent seal flaps and divergent seal flaps.          The exhaust flap comprises a frame assembly with means for mounting in the engine and effecting its movement.       The frame assembly is particularly characterized in having an open frame with at least one rail having a receiving channel.  A removable baseplate dimensioned to slide into the receiving channels and a retainer means for attachment to the frame assembly to securely hold the baseplate in the frame assembly are also provided.          The retainer means is readily removed to permit replacement of the baseplate while the exhaust flap is still mounted in the engine.  The removable baseplate prolongs the service life of the exhaust flap due to a decrease in temperature induced stresses.  Additionally, maintenance costs are substantially reduced by the ability to readily remove and replace a damaged baseplate.

Abstract: Speaker independent recognition of small vocabularies, spoken over the long distance telephone network, is achieved using two types of models, one type for defined vocabulary words (e.g., collect, calling-card, person, third-number and operator), and one type for extraneous input which ranges from non-speech soundsto groups of non-vocabulary words (e.g. 'I want to make a collect call please').  For this type of key word spotting, modifications are made to a connected word speech recognition algorithm based on state-transitional (hidden Markov) models which allow it to recognize words from a pre-defined vocabulary list spoken in an unconstrained fashion.  Statistical models of both the actual vocabulary words and the extraneous speech and background noises are created. A syntax-driven connected word recognition system is then used to find the best sequence of extraneous input and vocabulary word models for matching the actual input speech.

Title: Process and device for continuous cooking of cellulose
Inventor: SILANDER RISTO
IPC: D21C7/00
Filed: 1990-04-26
Abstract: Abstract The invention relates to a process for continuous cooking of cellulose. In the process, wood chips (11) are impregnated (1) with cooking lye (10), after which the wood chips impregna-ted with cooking lye is mixed (27) with spent liquor (18) in order to transfer (12) it into the upper portion of a pressu-rized digester 82). The transfer liquor used for the transfer of the wood chips in the preceding step is separated (26) from the impregnated wood chips in the upper portion of the digester (2) and is recycled (13,14) to the preceding step. After this, the chips are conducted from the digester (2) downwards into the cooking zone (24) and from there on to the washing zone (24), whereby a mixture of spent lye and wash lye, i.e. spent liquor (18) is removed from between the coo-king and washing zones (19) and a portion (21) of the liquor removed from the digester (2) is expansion evaporized (5,6) in order to recover heat in the form of steam (22,23). In or-der to improve the heat consumption of the method and to re-duce the steam consumption, the spent liquor (18) is mixed with the impregnated chips before transferring these into the upper portion of the digester (2), whereas a corresponding portion (21) of the transfer liquor (13) separated from the upper part of the digester (2) is conducted to the expansion evaporation (5,6) and from there on to the chemicals recovery (17). The invention also relates to a device for implementing the above process.
