Patent CA-2206297-A1 (CA)
Inventor: MIMNAGH WINSLOW MICHAEL
IPC: G11B7/24097
Filed: 1996-09-24
Abstract: Le support d'informations faisant l'objet de cette invention est du type optiquement inscriptible, tel qu'un disque compact à enregistrement effaçable ou un disque compact inscriptible une seule fois. Les informations peuvent être enregistrées sous la forme d'une piste de motifs sur le support d'informations. Le fabricant prévoit que ce support d'informations contienne ses propres informations, telles que les informations relatives à le puissance d'écriture à utiliser. Il est souhaitable que les motifs aient des dimensions constantes, quelle que soit la vitesse à laquelle elles sont enregistrées. Le processus d'enregistrement par lequel s'effectue l'opération d'enregistrement est par conséquent adapté à la vitesse d'enregistrement. Afin que cette adaptation corresponde audit support d'informations, on prévoit que celui-ci contienne des informations relatives à la vitesse, indiquant le processus d'enregistrement relatif à une vitesse d'enregistrement, par exemple une vitesse de référence (V1-V3), tandis que les paramètres d'enregistrement restants (W1-W3) sont donnés pour une vitesse d'enregistement minimum et/ou maximum à laquelle est enregistré le support d'informations. Le dispositif utilisé lit les informations relatives à la vitesse contenues dans le support d'informations et adapte le processus d'enregistrement à la vitesse d'enregistrement qui doit être utilisée dans ce cas.

Title: Switching power supply apparatus and method
Inventor: SIMPKINS JOSEPH A
IPC: H02M3/335
Filed: 1996-01-22
Abstract: A switching power supply (100) having a power steering clamp (116) is disclosed. The power supply (1()D) may suitably include a pulse width modulator controller which controls a first switch for controlling the flow of energy into and out of a transformer (120). The power steering clamp (116) suitably includes a second switch, clamp diodes, and circuitry for driving the gate of the second switch. The circuitry for driving the gate of the second switch is preferably controlled by the pulse width modulator controller. Use of the power steering clamp (116) permits leakage energy to be rerouted subsequently to the transformer. This feature may improve the efficiency of the circuit and also avoids the need for heat sinks to prevent overheating of circuit components. Such a switching power supply (100) is particularly suitable for use in high density devices, such as a banknote or bill validator.

Title: Method and apparatus for predicting structural integrity by estimating modal damping factor
Inventor: DIMAROGONAS ANDREW D
IPC: G01M7/00
Filed: 1996-05-31
Abstract: The integrity of structures may be determined by either one of two methods. In a first method, an impulse of energy is introduced into the structure (20), such as by striking the structure (20), and the induced vibration is measured and the modal damping factor is calculated, the modal damping factor being directly related to the integrity of the structure (20). In a second method, a continous energy input is provided to the structure (20) for inducing a continous vibration in the structure (20). This continous vibration is measured with a transducer (28) and a modal damping factor is calculated with a computer (32). The computer uses an algorithm to estimate the modal damping factor of the structure by calculating a theoretical response of an idealized system from several assumed parameters and varying those parameters.

Abstract: A brewing apparatus is provided including a housing with a water inlet channel, a heater to heat water delivered through the channel and a water dispenser within the housing for providing a spray of hot water to a brewing pot.  The brewing pot is releasably attachable to the housing and includes a filter receptacle positioned to receive the spray of water and outlet aperture for allowing brewed tea to exit. A filter basket for containing the tea leaves is lodged within the filter receptacle. The basket has a base with a wire mesh screen and an integrally formed non-porous siphon shroud projecting upwardly from a central area of the floor base, the shroud being closed at the top while open at the bottom. A siphoning tube is lodged within the aperture of the filter receptacle and open at both ends. When nested, the siphon shroud surrounds the siphoning tube to create a siphon arrangement for continuously removing tea extract fluid from the filter basket. In an alternate preferred embodiment, the apparatus includes a fluted paper filter with a centered aperture fitting over the siphon shroud for nesting within the filter basket. Tea leaves are placed within the paper filter instead of directly within the basket.

Inventor: RACINE JEAN-PIERRE
IPC: B04B7/18
Filed: 1998-01-30
Abstract: This centrifugal apparatus comprises a primary frusto-conical filter screen rotating about a vertical axis, which is closed at its smaller diameter end and which is surrounded at its larger diameter upper end by a flat horizontal imperforate ring. A secondary cylindrical. filter screen is fixed to and upstands from the periphery of the flat imperforate ring. The solid-liquid mixture is fed to the bottom of the primary filter screen and moves up under centrifugal force, the liquid being filtered and discharged into a surrounding casing. The solids move onto the ring and the liquid is further filtered through the secondary filter screen which retains the solids, being cylindrical. After the desired humidity content of the solids is reached, a scraper is lowered onto the ring to scrape the surface of the same and also the inner surface of the cylindrical secondary filter screen to remove the solids.
