Inventor: KOENIG JACQUES
IPC: C01B21/26
Filed: 1997-09-26
Abstract: Provided is a process having an increased production capacity for nitric acid, which moves can be operated safely and efficiently.  The process comprises forming a reaction mixtures by mixing air, ammonia, oxygen and an inert cooling fluid, preferably water, and then reacting the ammonia with oxygen in a reaction zone to form nitric oxide.  The amount of inert cooling fluid in the reaction mixture is sufficient to control the temperature of the mixture and maintain the ammonia percentage below the lower explosion limit for the mixture.   The nitric oxide produced in the reaction zone is then oxidized to nitrogen dioxide and its dimer, with additional oxygen being introduced into the process for oxidizing the nitric oxide.  The nitrogen dioxide and its dimer is then reacted with water to form the nitric acid.  The dual injection of oxygen into the ammonia reaction mixture and into the nitric oxide oxidizing step, together with the use of the inert cooling fluid in the ammonia reaction mixture, has been found to provide increased nitric acid production while allowing one to respect the constraints of good product bleaching, avoid catalyst loss due to volatilization, and operate under conditions below the lower explosion limit of the ammonia mixture.

Title: Ultra-high-speed semiconductor optical modulator with traveling-wave electrode
Inventor: KAWANO KENJI
IPC: G02F1/017
Filed: 1997-10-15
Abstract: A wideband semiconductor electro-absorption optical modulator including a semiconductor core shorter in absorption-peak wavelength than a wavelength of optical signal, and an electrode for applying an electric signal to absorb the optical signal by shifting the absorption-peak wavelength to a long wavelength region when a voltage is applied, wherein an electric signal input port and an electric signal output port are disposed so that the electrode is constructed in the form of a traveling-wave electrode, and a total thickness of non-doped layers including the semiconductor core is reduced to decrease a driving voltage.  Degradation of optical modulation bandwidth and reflection characteristics of the electric signal caused by mismatching of characteristic impedance to an outer circuit are reduced by decreasing an interaction length of the electric signal and the optical signal.  Further, mismatching of characteristic impedance is corrected by adjusting a doping concentration of a p-type or n-type doped layer located above or beneath the semiconductor core.
Patent CA-2219040-A1 (CA)
Inventor: SVENSSON KJELL
IPC: H02J5/00
Filed: 1997-11-13
Abstract: A system for transmitting power over a direct voltage network. A first power station connects one alternating voltage network to the direct voltage network. The first power station includes a converter for bidirectionally transferring power between the direct voltage network and the alternating voltage network. The converter maintains constant value of voltage on the network, or operates in a second alternative mode of controlling constant current between the alternating voltage network and the direct voltage network. When the voltage on the direct voltage network drops below a reference value, a second power station connected to the direct voltage network and to a remaining alternating voltage network takes over the voltage regulation function. The second power station prior to taking over the voltage regulating function was in a current regulating function. In this way, when the first station reaches its limits of voltage regulation, the second station is enabled to take over the voltage regulating function switching out of a current regulating function.

Title: Dielectric resonator device
Inventor: ISE TOMOYUKI
IPC: H01P7/06
Filed: 1997-12-10
Abstract: A dielectric resonator device has a dielectric member.          Electrodes are respectively formed on the upper and lower surfaces of the dielectric member.  The dielectric resonator device resonates at a mode having electric field components in a direction perpendicular to the upper and lower surface of the dielectric member.  The electrodes formed on the dielectric member are each formed of a thin film multi layered electrode produced by alternately laminating thin film electrode layers and thin film dielectric layers.  Each thin film dielectric layer which is sandwiched between the thin film multi layered electrode layers serves as a dielectric resonator.          Accordingly, the thin film multi layered electrode acts as a laminated structure of a plurality of dielectric resonators.  Thus, a current distributes over the plurality of thin film electrode layers, thereby alleviating the current concentration on the surface of the dielectric member.  As a consequence, conduction losses of the overall resonator unit are reduced.

Abstract: An active feed loader for a paintball gun. The active feed loader includes a generally horizontal interior passageway or channel having a first end in communication with an interior space of the housing where paintball are housed. A rotatable paddle positioned in the interior space forces paintballs out of the housing and through the interior passageway or channel until they drop through an opening therein into a vertical outfeed tube where they form a paintball stack. When the paintball gun is fired, the paintball stack. is depleted until a sensor detects the absence of a paintball at a specified location within the outfeed tube. Upon detecting the absence, the sensor activates a motor which rotates the paddle to force paintball through the interior passageway and into the outfeed tube where they replenish the paintball stack. When the stack is fully replenished, the sensor will detects the presence of a paintball at the specified location and deactivate the motor, thereby stopping the paddle. If the loader includes a channel an elongated top wall of a directional plug prevents paintballs from dropping into a open top end thereof.
