Patent CA-2333051-A1 (CA)
Inventor: WERDINIG HELMUT
IPC: B07B1/18
Filed: 1999-05-17
Abstract: The aim of the invention is to provide a sure and trouble-free sieving of a solid material (R) using a sieving device (1) having an arrangement which is as simple as possible. To this end, a spiral (10) formed by a rod (8) which is wound in a helicoidal manner, or a plurality of such rods (8) are provided as a sieving device. Said rod(s) (8) can rotate around a longitudinal axis (3).  For sieving, the solid material (R) is introduced into the inner space (11) formed by the rod (8), preferably with the assistance of an aligning device (2) for longitudinally extended solid material parts (16). The spirals (10) comprise, in particular, a bend so that the lodged solid materials (R) can automatically detach themselves. The sieving device (1) is especially suited for sieving pyrolysis residual material.

Title: Scheduling of bursty data streams over a fixed capacity channel
Inventor: LECHLEIDER JOSEPH WILLIAM
IPC: H04L12/56
Filed: 1999-06-22
Abstract: Techniques whereby a transmitter/receiver pair are cooperatively arranged to  buffer incoming data to both the transmitter and the receiver. The transmitt er and receiver of the pair are coupled, generically, by pre-existing channel which has a known, fixed capacity. The transmitter/receiver pair exploits whatever delay is permissible, as determined by end-users of the data, for t he data stream or streams that are using the channel for the purpose of accommodating periods of excessive instantaneous aggregate data transfer demands. The matched transmitter/receiver pair thereby permits (i) the transmission of a variable rate stream over a channel with capacity less tha n the peak rate of the stream, or (ii) the multiplexing of variable and/or fix ed rate data streams.

Title: Raman amplified optical system with reduction of four-wave mixing effects
Inventor: STENTZ ANDREW JOHN
IPC: H04B10/17
Filed: 2001-02-13
Abstract: A transmission fiber for use in a Raman amplified optical communication system is formed to exhibit certain characteristics that limit modulation instability and four-wave mixing in the amplification region, thus reducing the noise component present in the transmission system. In particular, the group-velocity dispersion (denoted as D and measured in terms of ps/nm-km) is restricted to be either non-positive or greater than +1.5ps/nm-km in the pump wavelength range of interest (a typical pump wavelength range being 1430-1465nm). Preferably, the magnitude of the dispersion is kept below a value of 10 ps/nm-km in the signal wavelength range of interest (e.g., the "C" band or "L" band). Four-wave mixing is reduced by ensuring that the zero-dispersion frequency of the transmission fiber is not centered between the pump frequency and a frequency experiencing Raman gain.

Title: A simple implementation of turbo decoder
Inventor: JIN GARY QU
IPC: H03M13/41
Filed: 2001-02-28
Abstract: A method and apparatus for decoding convolutional codes used in error-correcting circuitry for digital data communication. To increase the speed and precision of the decoding process, the branch and/or state metrics are normalized during the soft decision calculations, whereby the dynamic range of the decoder is better utilized. Another aspect of the invention relates to decreasing the time and memory required to calculate the log-likelihood ratio by sending some of the soft decision values directly to a calculator without first storing them in memory.

Title: Plie a combustible a membrane electrolyte polymere
Inventor: ROSENMAYER VOLKER
IPC: H01M8/0239
Filed: 1999-09-02
Abstract: Avec toutes les structures de diffusion de gaz connues jusqu'ici, il est impossible de garantir un équilibrage du bilan hydrique de la pile à combustible, une protection contre le dessèchement, ainsi qu'une prévention de la formation de dépôts d'eau, tout en obtenant une répartition régulière des gaz de réaction. Avec la structure de diffusion de gaz selon l'invention, on obtient, grâce à un système stratifié, un gradient de la perméabilité aux gaz, perpendiculairement à la membrane. Grâce à cette structure, à une température de service appropriée et avec une stoïchiométrie appropriée des réactifs, on est assuré d'obtenir une humidification constante et optimale de la membrane par l'eau formée, en chaque point. On peut donc renoncer à l'utilisation de systèmes d'humidification supplémentaires.

Title: Automated material distribution control for stretch blow molded articles
Inventor: ROBERTS EDDY
IPC: B29C49/78
Filed: 2001-05-09
Abstract: A method for inspecting the material distribution of a sequence of stretch blow molded containers or other articles in a continuous production process, by providing injection molded parisons, each parison having at least one indicator, typically two or more indicators, for detecting material distribution at a predetermined position along the axial extent of the parison. Each of the parisons is subjected to a heating stage in the continuous production process, generally by exposure to infrared heating. Each heated parison is then subjected to a blow molding process, which can be a stretch blow molding process, so that each material distribution indicator is transformed to a corresponding position along the axial extent of the blow molded article. A detector is positioned to detect the location of each indicator on each blow molded article from a given mold in the production process. A computation is then made to determine for each blow molded article a material distribution outcome or profile based on the detected locations of each indicator. This information on material distribution is them matched to a prescribed profile for the particular container design and any discrepancy beyond some preset tolerance value is employed to reject the out of tolerance item from the production line, and to modify a step of the manufacturing process such as the infrared heating pattern.

Title: Locking mechanism for movable subframe of semi-trailers
Inventor: HESS TIMOTHY V
IPC: B62D53/06
Filed: 2000-01-07
Abstract: A locking mechanism for a movable subframe of a semi-trailer includes at least a pair of transversely spaced pins (49, 59). Each pin is extendable into and retractable from an opening formed in its respective longitudinally extending main member (11) of the subframe and a selected aligned one of a plurality of openings formed in its respective longitudinally extending rail of the trailer main frame. An elastomeric bladder (131) is disposed between the pins and is operatively connected to one or more cables (154) and/or linkage members which in tum are operatively connected to the pins. When the bladder is voided of air and is in its collapsed state, sufficient slack exists in the bladder, cables and/or linkage members to enable the bias force of a coil spring (56) disposed about each of the pins to independently cause the pins to extend through their respective aligned openings to lock the subframe in a selected longitudinal position with respect to the trailer main frame. When air is introduced into the bladder, it distends or elongates and in tum shortens the length of the portions of the bladder, cables and/or linkage members which are in transverse alignment with the pins, to impart a linear retraction force on the pins which overcomes the bias force of the springs to independently retract each of the pins from its respective main frame opening enabling repositioning of the subframe beneath the trailer frame.
