Title: A cage compactor dryer apparatus for treating waste materials
Inventor: LA GIOIA ANTONIO
IPC: F26B23/10
Filed: 1999-03-24
Abstract: A cage like compactor and dryer apparatus comprising a cylindrical body (10) formed by conduits (11) arranged according to its generatrix lines and run through by a heat transfer fluid intended to heat the waste material contained therein (textile or foodstuff wastes, municipal solid wastes). The individual conduits (11) are spaced apart so as to form vapour outflow paths for the water vapour, having longitudinal dimension corresponding to the whole heating length of the cylindrical body (10). Pressure plates (14) form the mobile bases of the cylindrical body (10) in order to generate the needed axial pressure.  Suitable hoops (12) arranged in spaced apart relation constrain said conduits (11) in order to withstand the radial components of the longitudinal forces. The ground connections of the cylindrical body (10), when it is horizontally mounted, are realised by running trolleys (15) aimed at minimising the stresses generated by the temperature variations.

Abstract: La cristallographie aux rayons X peut être utilisée pour sélectionner par criblage des composés qui ne sont pas des ligands connus d'une biomolécule cible, du point de vue de leur capacité à fixer cette biomolécule cible. Le procédé faisant l'objet de cette invention consiste à produire un cristal d'une biomolécule cible; à exposer ce cristal de biomolécule cible à un ou plusieurs échantillons de test; et à obtenir un diagramme de diffraction de cristal aux rayons X pour déterminer la formation d'un complexe ligand/récepteur. La cible est exposée aux échantillons de test soit par cristallisation conjointe d'une biomolécule en présence d'un ou de plusieurs échantillons de test soit par trempage du cristal de la biomolécule dans une solution d'un ou de plusieurs échantillons de test. Dans un second mode de réalisation, des informations structurelles provenant des complexes ligand/récepteur servent à élaborer des ligands ayant un pouvoir de fixation plus serré, ayant une capacité de fixation plus spécifique, ayant une plus forte activité biologique ou ayant un plus grand profil de sécurité. Un troisième mode de réalisation de cette invention consiste à identifier ou à élaborer des fractions biologiquement actives par le procédé de cette invention. Dans un quatrième mode de réalisation, un cristal de biomolécule ayant un site actif facilement accessible est formé par cristallisation conjointe de la biomolécule avec un ligand dégradable et par dégradation de ce ligand.

Title: A method of and device for improving a drainage of aqueous humor within the eye
Inventor: STEGMANN ROBERT
IPC: A61F9/007
Filed: 2001-01-22
Abstract: A method for improving a drainage of aqueous humor in an eye of a living being and a device for maintaining the drainage of aqueous humor are described, wherein a first incision is made in a lamellar section of the sclera to form a first scleral flap which is then folded upwards in the direction of the cornea, thereby creating a first recess in the sclera. A second scleral flap is formed by incising a second lamellar section in the area of the recess and lifted upwardly in the direction of the first sclera flap, thereby creating a second recess and exposing a portion of the Schlemm's canal for permitting injection of a highly viscous medium.      At least one support element is implanted in the lumen of the Schlemm's canal on each of both sides of the second recess and, optionally, in the exposed portion of the Schlemm's canal, whereby each of the support elements is made of a material that is decomposable by the tissue of the Schlemm's canal and/or aqueous humor. For formation of a gap-like opening, the second scleral flap or a portion thereof is detached from the partially aqueous humor-permeable Descemet's membrane in the area of the Schwalbe's line, and the detached portion is held open by several protrusions formed on the support element implanted in the exposed portion of the Schlemm's canal.

Inventor: ARCHAMBAULT JEAN-LUC
IPC: H04J14/02
Filed: 2000-03-22
Abstract: Multiplexer (1300) includes a plurality of conventional 1 x 8 combiners (1310-1 to 1310-10), for example, each having eight inputs receiving a respective one of eight channels. Combiners (1310-1 to 1310-10) can include one or more of the following: dielectric filters, fiber couplers, planar waveguides, arrayed waveguide routers, and appropriate combinations of fiber Bragg gratings and circulators. Combiners (1310-1 to 1310-10) combine the received channels onto corresponding outputs, which are coupled to respective optical attenuators (1312-1 to 1312-9). A series of cascaded combiners, including for example optical filter elements (1314-1 to 1314-9), generally receive optical signal inputs from corresponding optical attenuators (1312-1 to 1314-9), and add these signals to signals input from a preceding optical filter element. In particular, filter element (1314-1) adds channels (.lambda.1 to .lambda.8) received from combiner (1310-1) and channels (.lambda.9 to .lambda.16) output from combiner (1310-2) via attenuator (1312-1). The aggregated channels, channels(.lambda.1 to .lambda.16), are passed to filtering element (1314-2), which adds channels (.lambda.17 to .lambda.24) output from attenuator (1312-2) thereto. In a similar fashion channel groups (.lambda.25 to .lambda.32, .lambda.33 to .lambda.40, .lambda.41 to .lambda.48, .lambda.56 to .lambda.64, and .lambda.72 to .lambda.80) are successively added by filters (1314-3 to 1314-9). The final filtering element stage (1314-9) outputs the entire aggregation of channels, ((.lambda.1 to .lambda.80) onto a single output fiber (1316).

Filed: 1999-12-13
Abstract: A processing system has an instruction processor (IP) (1), register files (3 and 4) for storing data to be processed by the IP (1), such as a thread context, and a register transfer unit (RTU) (5) connected to the register files (3 and 4) and to the IP (1). Register files (3 and 4) may assume different states, readable and settable by both the RTU (5) and the IP (1).  The IP (1) and the RTU (5) assume control of register files (3 and 4) and perform their functions partially in response to states for the register files, and in releasing register files (3 and 4) after processing, set the states. The invention is particularly applicable to multistreamed processors, wherein more register files (3 and 4) than streams may be implemented, allowing for at least one idle register file in which to accomplish background loading and unloading of data. The invention is also particularly applicable to processing systems dealing with real-time phenomena such as data packet processing in network routers.
