Title: Spatially variable filter laser wavelength monitoring/control
Inventor: MIRMAN ILYA
IPC: H04B10/43
Filed: 1998-11-24
Abstract: A feedback controlled laser diode communication device is disclosed that, as is common, has a laser diode that is modulated in response to an input signal to generate an optical signal, encoding the input signal. Spatially variable passband filter material, however, is arranged to receive at least a portion of the optical signal generated by the laser diode, preferably from the rear facet, and at least one detector is used to detect the thus filtered optical signal. Control circuitry then controls a wavelength of the laser diode based upon the response of the detector(s) to thus provide feedback control. As such, the device is particularly applicable to maintaining the tight channel spacings found in wavelength division multiplexed systems.
Patent CA-2310790-A1 (CA)
Inventor: STRAUS DAVID
IPC: A23L27/00
Filed: 2000-06-06
Abstract: The invention relates to a process for preparing cyclodextrin inclusion complexes that increases the efficiency of the complexation so that a higher percentage of the active is recovered as a cyclodextrin inclusion complex. The process involves adding a cyclodextrin to a solvent in a reaction vessel, adding an active to the cyclodextrin solution with stirring, and allowing the mixture to stir for an appropriate amount of time and at a sufficient temperature to form an inclusion complex between the cyclodextrin and the active. A solids content increasing agent such as gum acacia, maltodextrin, modified dextrins, or mixtures thereof, is then added to the solution to increase the total solids content of the solution and the solution is at 25°C and 40°C and relative humidity of 53 percent dried to recover the cyclodextrin-active inclusion complex as a dry powder with the amount of active in the powder ranging from 1 to 20 percent by weight of the complex. The invention also relates to cyclodextrin inclusion complexes prepared by this process.

Patent CA-2313345-A1 (CA)
Title: Tension control system and method for reducing front end and tail end overfill of a continuously hot rolled product
Inventor: SHORE T MICHAEL
IPC: B21B37/52
Filed: 2000-07-04
Abstract: A system for controlling front and tail end gauge of a continuous hot rolled product in a rolling mill includes first and second individually driven roll stands arranged successively along said pass line in advance of a group of roll stands. A controller adjusts the operating speed relationship between the first and second individually driven roll stands to achieve an increased level of tension in the front and tail end segments of the product passing between the first and second individually driven roll stands. The increased level of tension results in the decrease in product cross sectional area sufficient to compensate for the lack of cross sectional area reduction resulting from the absence of interstand tension experienced by said front and tail end segments while being rolled in the group of roll stands. To control the gauge of the front end of the continuous hot rolled product, the controller commands a decrease in the speed of the first roll stand as front end approaches the second individually driven roll stand, which is located adjacent to and downstream of the first individually driven roll stand. The reduction of the speed of the first roll stand below a nominal rolling speed establishes the increased level of tension of the product between the first and second roll stands when the front end enters the second roll stand. When the front end has passed the first roll stand, the controller commands the speed of the first roll stand to return to the nominal roll speed to roll the segment of the product between the front and tail ends. To control the gauge of the tail end of the product, the controller commands a decrease in the speed of the first roll stand as the tail end approaches the second individually driven roll stand.

Filed: 2000-08-02
Abstract: A improved tilt rotor aircraft comprising an airframe, at least one wing member coupled to the airframe, and at least one tilt rotor assembly carried by the at least one wing member. The tilt rotor assembly is actuated by a conversion actuator. The improved tilt rotor aircraft includes a low-height tunable downstop assembly for absorbing oscillatory vibration loads, such as pitch loads and yaw loads. The low-height tunable downstop assembly comprises a pivotable striker assembly having an adjustable stiffness, and a cradle assembly adapted to releasably receive the striker assembly. The striker assembly is attached to the tilt rotor assembly and the cradle assembly is attached to the wing member. A plurality of sensor modules are bonded to the cradle assembly. The sensor modules include a plurality of strain gages arranged to sense shear strain in the cradle assembly. The sensor modules are electrically coupled to sensor circuits and flight control computers. As the conversion actuator pivots the tilt rotor assembly into the airplane mode, the conversion actuator forces the striker assembly into contact with the cradle assembly at a selected preload. The sensor modules directly sense preload induced strain in the cradle assembly and send corresponding signals to the flight control computers via the sensor circuits. If the signals from the sensor modules indicate that the preload is insufficient to maintain stability in the aircraft mode, then a warning signal is sent to the pilot and a control signal is sent to the conversion actuator to increase the preload. Likewise, if the signals from the sensor modules indicate that the preload is too high, a warning signal is sent to the pilot and a control signal is sent to the conversion actuator to decrease the preload.

Title: Appareil et procede de reliure de livre
Inventor: MARSH JEFFREY D
IPC: B42C9/00
Filed: 1999-01-06
Abstract: Cette invention concerne un système qui permet d'effectuer la reliure parfaite d'un corps d'ouvrage (14) à l'intérieur d'une couverture en papier souple. La partie centrale (18) de la couverture possède une taille qui est fonction de l'épaisseur du livre à relier. Un adhésif activable est appliqué sur la surface interne de la partie centrale de la couverture. Le corps d'ouvrage est ensuite inséré dans la couverture de sorte que son dos (S) soit globalement aligné sur l'adhésif. La couverture est ensuite comprimée en force contre le corps d'ouvrage à l'aide d'éléments presseurs (60a, 60b). Un cornet ultrasonique (66) est mis en contact de travail forcé contre la surface externe de la partie centrale de la couverture. On fait résonner ce cornet de manière à transmettre à l'adhésif une énergie ultrasonique qui est suffisante pour le faire fondre. On force ainsi l'adhésif à passer dans les bords des pages du corps d'ouvrage le long du dos, les pages du corps d'ouvrage étant également forcées de pénétrer dans l'adhésif le long de la partie centrale de la couverture. Lorsque l'on interrompt l'émission d'énergie ultrasonique, l'adhésif se solidifie instantanément et relie la couverture au corps d'ouvrage. Cette invention concerne également un procédé de reliure d'un livre.
