Abstract: L'invention concerne un procédé de réparation d'un système de transmission à fibre optique ~ multiplexage de longueur d'onde et à signaux solitons, dans lequ el les différentes longueurs d'onde (.lambda.1 à .lambda.n) du multiplex sont choisies de sorte à assurer, sur un intervalle (Z R) donné, un glissement relatif entre les différents canaux sensiblement égal à un multiple du temps bit, comprenant les étapes - d'introduction d'une longueur supplémentaire (13) de fibre optique dans le système de transission et - de compensation (15, 17;, 19) des effets de cette longueur supplémentaire sur le glissement relatif des différents canaux du multiplex. Elle concerne aussi un dispositif de réparation d'un tel système de transmission à fibre optique à multiplexage de longueur d'onde et à signaux solitons. L'invention évite les glissements relatifs des canaux du fait de l'introduction dans le système de transmission d'une longueur supplémentaire de fibre.

IPC: B01J20/285
Filed: 1997-04-04
Abstract: L'invention concerne des macrocycles calixpyrroles, calixpyridinopyrroles et calixpyridines, possédant 4, 5, 6, 7 ou 8 noyaux hétérocycliques, ainsi que leurs synthèses, dérivés, conjugués, multimères et supports solides. Ces macrocycles se sont avérés être des agents de liaison des ions et des molécules neutres efficaces et sélectifs, formant des ensembles supramoléculaires, ainsi que des agents de séparation des ions et des molécules neutres. Ils constituent des porphyrinogènes totalement méso, sans substituant hydrogène dont certaines molécules étaient déjà connues, mais pas les propriétés de liaison anionique ou moléculaire de celles-ci. Le mode de liaison, non covalent, est à l'origine une liaison hydrogène, ce qui donne un nouveau procédé de chromatographie en phase liquide, la chromatographie en phase liquide par liaison hydrogène. Parmi les autres applications utiles des macrocycles cités ici, on trouve le traitement de l'environnement par élimination des ions ou des molécules neutres indésirables, et l'élimination des phosphates en dialyse rénale.

Patent CA-2254168-A1 (CA)
Inventor: LAYNE JAMES L
IPC: B65G45/26
Filed: 1998-11-16
Abstract: An underguard assembly is provided for use with a modular conveyor of a conveyor system.  The underguard is formed of a flexible web that hangs beneath the conveyor to catch debris falling from the sides of or through the conveying surface.  To support the web, a stiffener rod is placed in an elongate pocket formed along each longitudinal edge.  Opposed support assemblies spaced along the sides of the conveyor frame hold the enlarged pocket formed by the stiffener rod.  An adjustment means is provided on each support assembly that allows the web to be easily attached and detached from the conveyor frame.  Further, the support assemblies adjacent the end of the conveyor are modified to support the web beyond the end of the conveyor.  This allows the web of a first modular conveyor to overlap with the web at the start of an adjacent modular conveyor, thereby providing a substantially seamless underguard function for a conveyor system.

Title: Process for the treatment of particulate matter by fluidisation, and vessel with apparatus to carry out the treatment
Inventor: LEE LL-OCK
IPC: C21B13/00
Filed: 1997-05-15
Abstract: In a process for the treatment of particulate matter by fluidisation the particulate matter is held and treated in a fluidised bed reactor (1,1', 1") with the treatment gas flowing from the bottom to the top. To minimise consumption of the treatment gas, and to reduce the entrainement of fines by the treatment gas, particulate matter with a wide ranging grain size distribution and a relative large content of fines is used and the empty pipe flow rate of the treatment gas in the fluidised bed (2) is kept smaller than the flow rate required for the fluidising of the larger particles of the particulate matter. The reduced material is taken via a transport pipe (6) to a melting gasifier (25) where in a melting gasifying zone (26) a reduction gas with CO and H2 content is produced from carbon and oxygen-containing gas which is introduced into the fluidised bed reactor (1") via a feed pipe (27).

Inventor: SPECTOR MAGALY
IPC: H04B10/29
Filed: 1999-06-17
Abstract: A method and apparatus are disclosed for providing optical channel adding/dropping capability within a WDM filter-bypass device. The device comprises an optical filter, an optical switch, and means for receiving a control signal to configure the optical switch. When configured in a filter state, the switch routes the WDM signal through the filter to drop, add or drop and add one or more pre-selected WDM channels. When configured in a bypass state, the WDM signal bypasses the filter. A series of filter-bypass devices may be interconnected to increase the number of optical channels that can be dropped or added.

Inventor: SULZER GERALD M
IPC: C07F9/22
Filed: 1998-01-21
Abstract: A substantially anhydrous mixture which comprises ammonium chloride, the triamide, and ammonia is formed either by adding ammonia to a mixture of the other components or by conducting, in the presence of the ammonia and an organic solvent, a reaction to form the triamide and ammonium chloride as coproducts.

Inventor: SILLEKENS PETER THEODORUS GERA
IPC: C12N15/09
Filed: 1998-02-25
Abstract: The sensitivity and reliability (robustness) of CMV mRNA detection are greatly dependent on the selection of suitable oligonucleotides for amplification, since there is sequence variation among strains of CMV  potentially in every region of the genome. The present invention is concerned with oligonucleotides that can be used as in the amplification and detection of human Cytomegalovirus (HCMV) mRNA.  These novel oligonucleotides show an improved sensitivity and robustness of CMV mRNA detection if compared with known sequences when used in amplification and detection. Furthermore a method for the diagnosis of HCMV disease is provided.

Title: Electrically addressable passive device, method for electrical addressing of the same and uses of the device and the method
Inventor: GUDESEN HANS GUDE
IPC: G11C11/21
Filed: 1998-06-17
Abstract: An electrically addressable passive device for recording, storage and/or processing of data comprises a functional medium in the form of a continuous or patterned structure which may undergo a physical or chemical change of state. The functional medium is realized as a homogenous or stratified structure comprising a least one substantially organic material. The functional medium comprises individually addressable cells which represent a registered or detected value or are assigned a predetermined logical value for the cell. The cell is provided between the anode and cathode in an electrode means which contacts the function medium in the cell and causes an electrical coupling therethrough, whereby the cell directly can be supplied with energy which effects a change in the state of the cell, the functional medium having an overall non-linear impedance characteristic, and said at least one substantially organic material of the functional medium being a polymer material. In the method the addressing comprises operations for i.a. detection and recording as well as further operations for writing, reading and switching of a logical value assigned to the cell, electric energy is applied directly to the functional medium of the cell in order to change its state and hence effect an addressing operation. It can be used in optical detector means, volumetric data storage devices or data processing devices.
