Patent CA-2271625-A1 (CA)
Inventor: KOCH GEORG
IPC: B01J38/00
Filed: 1998-06-08
Abstract: The invention relates to a method for renewed activation of honeycomb-shaped catalyst elements for denitrating flue gases from fossil fuel-fired boiler plants, specially coal-fired boiler plants in large power stations. According to the invention, each catalyst element is mechanically cleaned using oil and water-free compressed air before mounting. Subsequently, each element is subjected to wet chemical cleaning using fully desalinated water and dried with oil and water-free compressed air. The inventive method enables the activity of used catalyst elements to be increased from less than 50 % to more 83 % of original activity.

Title: Dispositifs pour augmenter la securite de vol dans les transports aeriens
Inventor: GIGEL TUICA
IPC: B64D25/00
Filed: 1999-06-01
Abstract: En raison de catastrophes aériennes qui ont eu lieu dernièrement, j'ai étudié  la possibilité de trouver une solution pour augmenter la sécurité de vol et de faire diminuer les écrasements dans les transports aériens, commerciale, indifférent de la cause de défectueusement: (électrique, mécanique, train d'atterrissage), sauf l'explosion et le feu.   Cette solution (dispositifs) que j'ai trouvée est facilement adaptable pour tous les modèles d'avions, est indépendante de la partie technique d'un avion. Dans ce cas, l'avion peut se déposer au sol en toute sûreté, indifférent des conditions. J'ai découvert que ces inconvénients peuvent faire diminuer les écrasements dans les transports aériens, par l'installation d'un "turbopropulseur d'air", procédé dans lequel se produit l'air, fournissant l'énergie de sustentation, transformée ensuite en pression de l'air soufflé, dans un ensemble des conduites fixes. L'entraînement d'air permet d'assurer la sustentation et de ralentir (freiner) la vitesse de vol, en tenant compte de la sustentation assurée par les ailes (des forces aérodynamiques:  éléments constitutifs). "TURBOPROPULSEUR D'AIR"fonctionne seulement si un automatisme donne un signal de démarrage et là aussi l'automatisme va permettre de transférer l'alimentation (à l'aide de l'inversor de source automatique) du côté du réseau de fonctionnement du turbopropulseur d'air. Pour une courte période de temps, le système normal opérera avec la source ("système") d'urgence, afin de s'assurer que le système d'urgence a vraiment retrouvé sa fiabilité. Après cette période de temps, les moteurs du réseau normal s'arrêterons automatiquement (s'il s'avérait qu'un défaut, côté "source" normale, apparaisse). En effet, l'ensemble destiné à imposer est capable de contrôler l'atterrissage et va opérer automatiquement, en fonction des besoins (défaut), indépendant de la partie technique d'un avion, de façon précise - remplaçant immédiatement et adéquatement la source normale d'utilisation, de manière que l'installation ne présente aucun danger, permettant de fournir un système sécuritaire et efficace. De nos jours, des équipements qui nous permettent d'améliorer la fiabilité des systèmes d'urgence sont utilisés. L'emploi de l'ordinateur, de micro-processeurs, de synchronisateurs et d'équilibreurs de charge électronique, l'inverseur automatique, ainsi que que de régulateurs électroniques, permettent de garantir aux utilisateurs des systèmes d'urgence, en remplaçant adéquatement la source normale d'utilisation, en dedans de 15 à 25 secondes. Dans les conditions normales, en utilisant ce système, il peut accomplir ses fonctions en permettant "le décollage et l' atterrissage fiable des avions".

Title: Photochemical singlet oxygen generators having enhanced singlet oxygen yields
Inventor: INGRAM DAVID WILLIAM
IPC: D06L4/75
Filed: 1998-01-22
Abstract: The invention relates to photochemical singlet oxygen generators useful as bleaching agents or anti-microbial agents in laundry detergent compositions or in hard surface cleaning compositions. The singlet oxygen generators described herein have enhanced singlet oxygen generation due to aromatic moieties tethered to the molecules, said aromatic moieties absorbing ultra violet radiation then re-emitting the radiation as fluorescence at a wavelength absorbable by the singlet oxygen producing photosensitizer unit. The increase in the number of photons having an absorbable wavelength provides an increase in the production of singlet oxygen.

Title: Method and apparatus for providing alarm security receiver with dialed number and caller i.d.
Inventor: DUBBLESTEIN DEAN
IPC: H04M1/57
Filed: 1999-08-27
Abstract: An ISDN or other enhanced bulk delivery telephone signal is processed by a channel bank receiver to preferrably produce a plain old telephone signal output having dialed number and caller I.D. as lead information. This signal is advantageously used by a security station receiver to distinguish different calling alarm panels which may not be uniquely identified by their own address. This information also allows more effective processing of telephone signals received by the security station.

Patent CA-2294471-A1 (CA)
Title: Method and arrangement for locking in a yig-tuned oscillator
Inventor: SCHEFFOLD BRUNO
IPC: H03L7/099
Filed: 1998-04-09
Abstract: The object of the invention is to provide a lock-in process and device for a YIG-tuned oscillator which takes into account ageing and hysteresis of the YIG-tuned oscillator. This object is attained in that during a predetermined frequency change, the frequency of the YIG-tuned oscillator (1) is preset by means of a microprocessor (17) that progressively changes the current (ISP) in the main tuning coil (13) of the YIG-tuned oscillator (1) by an iterative capture routine, until the capture range (.DELTA.FM) of the switched-on frequency-locked loop, which changes with the coil current (ISP), includes the new operating frequency (fSET). The switched-on frequency-locked loop then pulls the oscillator frequency into the capture range of the PLL and the PLL  locks-in the oscillator frequency to the new operating frequency (fSET). The microprocessor (17) interrupts the capture routine when a PLL-LOCK detector (11) announces to the microprocessor (17) that the new operating frequency (fSET) has been successfully locked-in. The invention is used in a process for locking-in a phase-locked loop (PLL) to a YIG-tuned oscillator whose frequency is brought into the PLL capture range by a frequency-locked loop equipped with a frequency discriminator. When the PLL is locked-in, the frequency-locked loop can be switched off.

Title: Method and apparatus for external band selection of a digital microwave radio
Inventor: GRENON JEAN-FRANCOIS
IPC: H04B1/40
Filed: 1998-07-17
Abstract: The system and method of the present invention facilitates the selection of a portion of an operating bandwidth and frequency of a digital microwave radio. The components include a transceiver module (400) mounted to a mounting plate (402) having waveguide ports (404, 405). The input and output of the receiver and transmitter portions of the transceiver module (400) occur through the two waveguide ports (404, 405) of the plate. A diplexer (406) inserted within the slot of an interface (410) is externally mounted in relation to the mounting plate (402) and to transceiver module (400). The microwave energy from the transceiver module (400) is coupled through the mounting plate (402), diplexer (406), interface (410) and antenna (420). Because of the external mounting arrangement of the diplexer (406), interface (410), selecting an operating portion of the available bandwidth may occur after complete manufacture of the digital microwave radio.
