Abstract: L'invention concerne des procédés de synthèse de matériaux zéolitiques à grand pore associés de manière structurelle à la zéolite Béta et caractérisés par le pH relativement bas du milieu de synthèse et par l'utilisation d'anions F?-¿ comme agent de minéralisation. L'invention concerne en outre les matériaux ainsi obtenus caractérisés par leur très haute stabilité thermique, leur faible concentration de défauts SiO?-¿ ou SiOH, leur large plage de composition chimique, leur grand pore et caractérisés en ce que leur calcination permet d'obtenir la forme acide sans avoir recours à des processus d'échange cationique. Ces matériaux, quoiqu'ils soient associés à la zéolite Béta, présentent parfois des différences considérables par rapport à celle-ci. L'invention concerne aussi l'utilisation du matériau obtenu lors de processus catalytiques de transformation d'hydrocarbures et lors de processus d'oxydation. Le procédé consiste à chauffer à une température allant de 363 à 473K un mélange réactionnel contenant une source d'au moins un élément tétravalent (T(IV), éventuellement une source d'un élément T(III), éventuellement H¿2?O¿2?, un cation organique structurant, une source d'anions F?-¿ et de l'eau, la présence de cations alcalins n'étant pas nécessaire.

Patent CA-2295184-A1 (CA)
Inventor: NESS RONALD JAMES
IPC: F21S9/02
Filed: 1998-06-08
Abstract: A night light device provides a low level illumination using electro-luminescent lighting (30D) which is automatically fumed on when motion near the device is detected by the device and if ambient lighting level is low. When the ambient light level is above a specified level so that it is possible to see without artificial light, the device is inactive. A high intensity lighting feature (30F) allows the device to be used as a flashlight in emergencies since the device is fastened to a wall in such a way that it is easily and quickly removed. The front face (10A) of the device provides a downwardly directed surface (10A-1) for projecting light toward the floor, and sideways directed surfaces (10A-2, 10A-3) for projecting light to each side. Spherical Fresnel lenses (30B-1) enable the device to detect motion over a 180 degree azimuth. The case (10) of the device may have phosphorescent doping so as to provide a dim illumination even when the device is not energized.

Title: Optical recording medium
Inventor: KASAMI YUTAKA
IPC: G11B7/125
Filed: 2000-02-16
Abstract: A phase change optical recording medium which enables optimum direct overwrite even under high speed high density conditions without degrading repetition durability or storage stability of recorded signals. To this end, the phase change optical recording medium has a recording layer formed at least of a phase change material and is recorded and/or reproduced with a laser light beam having a wavelength ranging between 380 nm and 420 nm. A ratio Ac/Aa, where Ac is the absorption rate of said recording layer in a crystalline state and Aa is the absorption rate of said recording layer in an amorphous state, is not less than 0.9, and a crystallization promoting layer promoting the crystallization of the phase change material is contacted with at least one surface of the recording layer. By exploiting the absorption rate control and the crystallization promotion in combination, it is possible to positively compensate the difference between the physical properties of the crystal phase and those of the amorphous phase to realize optimum direct overwrite.

Patent CA-2307250-A1 (CA)
Inventor: PAIAM REZA
IPC: G02B6/26
Filed: 2000-04-27
Abstract: This invention discloses an optical waveguide having a hybrid core. A first waveguide having a glass core is coupled to a polymer waveguide disposed adjacent and parallel thereto. The refractive index of the polymer is varied by applying heat to the region. In the absence of applied heat the device acts as an MMI coupler and when heat is applied, the refractive index difference of the glass and the polymer increases yielding a suppressed MMI. By the application of sufficient heat, the refractive index of the polymer can approach the cladding the device acts as a simple glass waveguide.  Other embodiments disclose the application of a voltage to an EO polymer or physically compressing a polymer region to effect an refractive index change within the polymer.

Patent CA-2317973-A1 (CA)
Inventor: SAYEED ZULFIQUAR
IPC: H04L27/26
Filed: 2000-09-08
Abstract: A terrestrial repeater is disclosed for use in a satellite transmission syst em that may also include a plurality of satellites. The terrestrial repeaters are implemented as  OFDM transmitters to minimize the channel impairments caused by multi-pa th propagation. The OFDM terrestrial repeaters differentially encode the transmitted signal over frequency, as opposed to time, in order to avoid channel phase distortion. The OFDM receiver allocates two unmodulated sub-carriers as pilot bins and there by provides two sub-carriers as a reference within each OFDM symbol. At the OFD M receiver, the two unmodulated pilot bins contain no phase information and provide a reference for the differential demodulation performed by the OFDM receiver. The OFDM transmitter operates in two modes, namely, a normal mode and a transmitter identifier information (TII) mode. The TII mode contains all of the function s of the normal mode, and also transmits a repeater identification signal with the customer data, using the inactive OFDM sub-carriers (bins). In a normal mode, the OFDM transmitter optionally fills unused (inactive) sub-carriers with zeroes and in a TII mod e, the OFDM transmitter uses at least some of the unused (inactive) sub-carriers to transmit the transmitter identifier information (TII). The predefined TII value is mapped  onto a set of complex symbols. The TII signal facilitates the receiver test equipment in associating the received signal with the terrestrial repeater(s) that generate the TII signa l.

Patent CA-2320564-A1 (CA)
Inventor: HOWARD MATTHEW E
IPC: G09G3/34
Filed: 2000-09-22
Abstract: The invention is an electric reusable paper sheet that uses a pattern of conductive charge-retaining islands on the outward-facing side of the first of two thin layers used to encapsulate a Electric reusable paper substrate which interact with conductive areas in the encapsulating sheet. The second encapsulating layer may also coated with a conductive material, or made of a conductive material, and may or may not be patterned. The Electric reusable paper substrate and two encapsulating layers comprise a sheet of Gyricon electric reusable paper on which images can be written and erased repeatedly. The patterned charge-retaining islands of the first encapsulating layer receive electric charges from an external charge-transfer device. After the charge-transfer device is removed, the conductive, charge-retaining islands hold electric charge, creating an electric field in the electric reusable paper sufficient to cause an image change.
