Title: Mattes de fibres de verre et de fibres de cellulose et procede de fabrication
Inventor: DONG DAOJIE
IPC: D21H13/40
Filed: 2000-07-25
Abstract: L'invention concerne un procédé de fabrication de mattes à deux composants, des mattes à deux composants en fibres de verre et en fibres de cellulose, et des procédés de fabrication correspondants. Le procédé de fabrication consiste à traiter une surface de cellulose avec un polymère cationique dans une suspension de cellulose, puis à utiliser un tensioactif pour disperser les fibres de verre dans de l'eau blanche à base de polyacrylamide. En règle générale, la suspension de cellulose et la suspension de fibres de verre sont compatibles, et on les combine pour former une matière à deux composants. Le procédé comporte plusieurs avantages par rapport aux techniques classiques. Premièrement, il est habituel que les produits de coupe à l'état humide soient inutilisables pour la réalisation de mattes à deux composants dans une eau blanche type, à base de tensioactif/polyacrylamide. Deuxièmement, alors que certaines autres fibres (par exemple, fibres de verre) peuvent être utilisées pour la fabrication de mattes à deux composants dans l'eau blanche type susmentionnée, le processus de réalisation est fréquemment interrompu et tend à produire des mattes de qualité très médiocre. Troisièmement, le procédé considéré permet de fabriquer très facilement des mattes à deux composants de haute qualité à la fois uniformes et présentant une structure dense ainsi qu'une faible perméabilité. Enfin, on peut utiliser ce procédé pour fabriquer une variété de produits de coupe à l'état humide compatibles avec les fibres de pâte de bois résineux ou de feuillus.

Title: Small-scale mill and method thereof
Inventor: BOSCH HENRY WILLIAM
IPC: B02C17/20
Filed: 2000-05-31
Abstract: A small-scale or micro media-mill and a method of milling materials or products, especially pharmaceutical products, use a dispersion containing attrition milling media and the product to be milled. The milling media can be polymeric, formed of polystyrene or cross-linked polystyrene, having a nominal diameter of no greater than 500 microns. Other sizes include 200 microns and 50 microns and a mixture of these sizes. The mill has a relatively small vessel (10) having an opening, an agitator (30), a coupling (50), and a motor. The agitator (30) can have a rotor (32) and a shaft (40) extending therefrom. The rotor (32) can be cylindrical or have other configurations, and can have tapered end surfaces. The coupling (50) can close the vessel opening (56), or attaching the coupling to the motor can close the opening. The coupling has an opening through which the rotor shaft (40) extends into the motor. A sealing mechanism (70), such as a mechanical or lip seals the shaft while permitting the rotor shaft to rotate.      The vessel can contain one or more ports for circulating the dispersion, where milling can be made in batches or recirculated through the milling chamber. The media can be retained in the vessel or recirculated along with the process fluid. The rotor is dimensioned so that its outer periphery is spaced with a small gap from an inner surface of the vessel.      The vessel also can have a way of cooling the dispersion.

Title: A packet scheduler and method therefor
Inventor: VILLIER ERIC
IPC: H04L12/56
Filed: 2001-01-15
Abstract: This invention relates to a packet scheduler and method therefor and in particular a scheduler for a Code Division Multiple Access cellular mobile communication system. In packet base systems it is important to schedule transmissions of packets carefully in order to maximise the capacity of the system. The scheduler has means (233) for selecting a candidate set of packets. The candidate set is fed to means (235) for calculating transmit powers required by remote terminals to transmit the packets based on the candidate set. The calculated transmit powers are fed to means (237) for modifying the candidate set in response to the calculated transmit powers and the modified set is fed to means (239) for scheduling the packets of the candidate set for transmission. The scheduler is in particular appropriate for third generation mobile communication systems.

Title: Full scale calibration of analog-to-digital conversion
Inventor: HANDEL PETER
IPC: H03M1/10
Filed: 2001-06-12
Abstract: Methods and arrangements enable ADCs (105) to be calibrated from reference signals with unknown parameters and/or with amplitudes that exceed the dynamic range of the ADCs (105). A given analog reference signal s(t) is supplied to an ADC (105). The output x(k) of the ADC (105) is used by calibration logic (320) to estimate at least one paramater of the reference signal. A FIR filter (455) accepts as input the x(k) signals and outputs and estimate ((k)) as the sampled instances of thes(t) signal. A reconstruction table is created that approximates the analog input signal in the digital domain using the knowledge of the analog input signal waveform type. The actual ADC (105) outputs are compared to the values in the reconstruction table to produce a correction table (350) for calibration. In an alternative embodiment, calibration logic (320) interpolates the output (x(k)) of the ADC (105) to reconstruct clipped portion(s) of the input analog reference signal s(t) when the amplitude of the input analog reference signals s(t) exceeds the full swing of the ADC (105).  The FIR filter can thereafter use the reconstructed signal from the interpolation.
