Inventor: MELI FAUSTO
IPC: H04B10/2519
Filed: 1997-03-10
Abstract: A method of selectively compensating for the chromatic dispersion   of   optical   signals   in   an   optical telecommunication  network,  comprising  the  steps  of transmitting at least two signals over a common portion of said network, separating at least one of the signals from the remaining signals at at least one point of the network,  conpensating for the chromatic dispersion of this  signal  and  recombining  said  signal  with  the remaining signals at said one point of the network. Preferably this method further comprises the steps of detecting  the  chromatic  dispersion  of  each  of  the signals  at at  least  one  point  of  the  network, identifying,  among  the  signals,  the  signals  to  be compensated,  for which the detected dispersion value does not fall within a range of predetermined values and compensating for the dispersion of said signals so as to make  them  fall  within  this  range  of  predetermined values.

Title: Moisture separator for digester gases and landfill gases and raw natural gases
Inventor: HLYNSKY JULIAN S
IPC: B04C5/14
Filed: 1997-03-24
Abstract: Two versions of centrifugal type separators capable of removing moisture from digester gases, landfill gases and raw natural gases are described. An upright housing has a cylindrical upper region (of a circular cross-section) and a conical lower region which tapers downwardly. A tangential inlet is located in an upper region of the housing. A gas outlet is located centrally in a top end of the housing. An outlet to remove separated liquid is provided at the bottom of the housing. There is a trap system that preferably includes a liquid holding tank for providing a positive water seal in order to prevent explosive gases from escaping through the liquid outlet. One version of separator is suitable for a high pressure gas stream, ie. 3.0 psig or higher, while the second version is suitable for lower pressure gas streams, i.e. from 6 inches to 30 inches of water.

Abstract: A device for temporarily holding a bottle capsule during a sealing operation. facilitate part of the domestic wine bottling operation. The device allows an intended user to temporarily keep a conventional secondary closure such as a capsule over the neck of a bottle such as a wine bottle regardless of the orientation of the bottle while the neck of the bottle is being inserted into a volume of hot liquid without the need for the user's hand to contact the hot liquid thus allowing for a simple domestic heat shrinking operation. The device has a grasping section, the grasping section being configured and sized so as to extend substantially along at least a portion of the body of the bottle. The device also has a spacing section extending integrally from the grasping section. The spacing section is configured and sized so as to extend substantially tangentially along the tapering section of the bottle .

Title: Improved acid gas emission control
Inventor: MYCOCK JOHN C
IPC: B01D53/83
Filed: 1995-11-02
Abstract: An apparatus and process is provided for scrubbing sulphur oxide gas from combustion flue gas with wet limestone particles. The process is carried out in a moving bed reactor (21) having louvered inlet (13) and outlet (14) sides which permit the flue gas to pass through the reactor while the limestone particles move downward. The high velocity of the flue gas passing through the reactor causes some of the scrubbing particles to be ejected through the outlet side of the reactor. Problems associated with the ejection of the scrubbing particles are avoided by providing a slot alongside the outlet side of the reactor. The slot is sized so that the flue gas passing therethrough will have insufficient velocity to entrain the ejected particles therein. Consequently, the particles will fall to the bottom of the slot where they can be recovered and recycled.

There is also provided a communications cable having more than two twisted pairs.  The insulating materials include polyolefins such as polyethylene, and fluorinated polymers such as fluorinated ethylene-propylene.  The insulating material may be used as either a solid or foamed material covering the conductor.  These insulated wires may be used in the transmission of electronic signals in a plenum-rated communications cable.

Title: Method for predicting the response to treatment with bcg of superficial bladder carcinoma
Inventor: SHAPIRO AMOS
IPC: C12Q1/68
Filed: 1997-05-23
Abstract: The invention relates to a method and kit for the prediction of the response of a patient suffering from superficial bladder carcinoma to treatment with bacillus Calmette-Guérin (BCG), by calculating the inducibility of the Interleukin-2 (IL-2) gene of the patient in a sample of peripheral blood mononuclear (PBM) cells from the patient receiving BCG.  The method includes the steps of culturing at least two aliquots of PBM from the patient where the cells in a first aliquot are cultured in the presence of an inducing agent for inducing expression of the IL-2 gene and the cells in the second aliquot are cultured in the absence of the inducing agent.  The extent of expression of the IL-2 gene is quantitatively determined for each aliquot.  The ratio of the extent of the expression of the IL-2 gene in the first aliquot to the extent of the expression of the IL-2 gene in the second aliquot is calculated, the ratio providing a measure of the inducibility of the IL-2 gene. The inducibility is in a direct relationship with the probability of entering remission, relapse or persistence of bladder carcinoma in the patient.  Patients with a ratio below about 1.5 can be treated either with a cytokine preparation, a second course of treatment with the BCG or a second course of treatment with the BCG in combination with a cytokine preparation to improve response.

Les techniques visant à modifier la surface des nanoparticules comprennent une technique de lyophilisation permettant de produire un enrobage adsorbé physiquement et une dérivation avec époxy permettant de fonctionnaliser la surface des nanoparticules de sorte qu'elles puissent lier de façon covalente des molécules importantes. Ces nanoparticules peuvent également comprendre des copolymères multiséquencés à activation et/ou terminaison époxyde ou hydroxy, présentant des segments hydrophobes qui peuvent être des segments de polycaprolactone ou hydrophiles. Elles conviennent à l'administration locale intravasculaire d'inhibiteurs des muscles lisses et d'agents antithrombogènes dans le cadre d'une intervention de sondage vasculaire ou cardiaque, telle qu'une procédure d'angioplastie à ballonnet; à une application directe sur des tissus et/ou des cellules dans le cadre de la thérapie génique, par exemple l'apport de gènes ou de segments de gènes ostéotropes dans les cellules osseuses souches; ou à l'administration par voie orale, dans une capsule entéro-soluble destinée à l'apport de vaccins à base de protéines/peptides.

Title: Bicomponent fibers having distinct crystalline and amorphous polymer domains and methods of making the same
Inventor: BRISTOW JAMES R
IPC: D01F8/12
Filed: 1997-06-17
Abstract: Novel bicomponent fibers have a polyamide domain and an amorphous non-fiber-forming polymer domain which is embedded entirely within, and thereby completely surrounded by, the polyamide domain. The preferred bicomponent fibers have a sheath-core structure wherein the polyamide domain constitutes the sheath and the amorphous non-fiber-forming polymer constitutes the core. Surprisingly, even though the core is formed of a non-fiber-forming polymer, the bicomponent fibers exhibit properties which are comparable in many respects to fibers formed from 100% polyamide. Preferably, the fibers are concentric sheath-core bicomponent fibers having a nylon sheath and a core formed from polystyrene, polyisobutene and poly(methyl methacrylate). Polystyrene, and particularly atactic polystyrene, is preferred as the amorphous polymer domain.
