Patent CA-2308498-A1 (CA)
Inventor: REIST WALTER
IPC: B65H29/02
Filed: 1998-12-09
Abstract: The invention relates to a method and device for buffering with the use of a closed gripper. The invention comprises transport means (20) which are provided with grippers (22), can move along a conveying section (10), and are located in the area of a buffer section (14) of the conveying section (10). Transport means are stored in such a way that the distance between the transporting means (20), said means being successively arranged in the buffer section (14), is essentially determined by the degree of opening of the grippers (22) or by the dimensions of the transport means (20). Said means are also stored in such a way that opened grippers (22) are at least partially closed without exercising a holding function in or before the area of the buffer section (14). To this end, a closing device is placed in an entry area (16) of the buffer section (14) which, for example, can be provided in the form of a closing connecting member (18) and can be displaced along the conveying section (10).

Title: Partial decoding of compressed video sequences
Inventor: WINE CHARLES MARTIN
IPC: H04N7/30
Filed: 1998-12-22
Abstract: Compressed video sequences generated using a (e.g., DCT) transform are partially decoded (202) to recover (204) the low-frequency transform coefficients (e.g., only the DC coefficients) from the encoded bitstream. The low-frequency coefficients are then used to generate blocks of image data that are subjected to motion-compensated inter-frame addition (206) to generate partially decoded images that can be used for subsequent processing, such as histogram analysis (208) for video parsing. The present invention avoids having to perform the computationally expensive inverse transform operations, while still achieving satisfactory results.

Inventor: YEE CHUNGKIN
IPC: A63B24/00
Filed: 2000-09-07
Abstract: An exercise treadmill is disclosed which includes various features to enhance user operation and to reduce maintenance costs. These features include handlebars with an upwardly curved center section and outwardly flared side portions along with pivoting rear legs for the treadmill frame. The control panel features include snap-in user trays and an overlay covering the numerical key pad along with an auxiliary control panel having a subset of user controls that are larger and more easy to use than the same controls on the main control panel. Maintenance enhancing features include the provision for access panels in the treadmill housing and a belt lubrication system that uses a priming pulse to clear the wax spraying nozzle. For injection molded parts such as the control panel, structural strength is enhanced by utilizing gas-assist injection molding to form structural ribs.  Another feature includes pre-glazing the treadmill belt. Sound and vibration are reduced in a treadmill by mounting the treadmill belt drive motor on motor isolation mounts that include resilient members. A further feature is a double sided waxed deck where one side of the deck is covered by a protective tape.

Patent CA-2330409-A1 (CA)
Inventor: JIANG JIAN ER
IPC: D21C3/00
Filed: 2001-01-05
Abstract: The amount of metals that can be removed from comminuted cellulosic fibrous material (such as wood chips) in the production of chemical pulp, prior to bleaching, is enhanced by extracting metals during an early stage of digestion, and prior to the addition of a chelating agent. After the material is steamed and slurried it is impregnated with cooking liquor at a temperature of 90°C or more, and during or after impregnation metals are removed by an extraction (e.g. in a continuous digester), which typically removes about 30% or more of the Mn. Prior to this extraction it is not necessary to introduce chelating agents, and undesirable to do so since they may compete or interfere with the natural removal of metals. After the extraction, such as during the first part of cooking, about 0.05-10 kg/dry ton of material of chelant (such as EDTA) is added, and the chelant combines with released metal ions in the slurry to produce metal complexes.  The metal complexes are substantially removed before bleaching. In this way more than 93% of Mn (and other undesirable metal ions) may be removed prior to bleaching with a minimal amount of chelating agent used.

Abstract: L'invention concerne des récepteurs DS-CDMA, et plus particulièrement le besoin de fournir un filtre accordé sur l'impulsion permettant d'éliminer les interférences entre puces. On utilise un récepteur RAKE CDMA. Au lieu d'appliquer un filtre accordé sur l'impulsion au signal d'entrée comme c'est le cas dans les systèmes selon l'état de la technique, on applique un filtre accordé sur l'impulsion à un bit à la séquence de dispersion, de préférence, à une séquence de bruit pseudoalétoire (PN) interpolée jusqu'à la fréquence de suréchantillonnage requise. Le filtre ayant une entrée à un bit, on peut remplacer les multiplicateurs par des sommateurs qui consomment moins de courant. Contrairement au nombre de multiplicateurs selon l'état de la technique, le nombre de sommateurs n'augmente pas avec la fréquence de suréchantillonnage.

Title: Waste treatment system
Inventor: VAN SLYKE VICTOR
IPC: C02F11/13
Filed: 2001-04-11
Abstract: A method of treating faecal waste material comprises flocculating the waste material, processing, e.g. filtering, the flocculated waste material to extract liquid from solid material, drying the solid material, processing the liquid to extract potassium and ammonia from the liquid, all within 24 hours, and preferably on average within 12 hours, of production of the waste material by animals. Since urea in urine and faeces takes a few hours to break down, the prompt treatment of the waste material is effected while ammonia remains trapped in solution, and consequently a larger portion of the total amount of ammonia in the waste material can be extracted from the liquid filtrate.

Title: Selectively delaying data communications in a wireless communication system to provide voice communications capacity
Inventor: JAWANDA JASTINDER
IPC: H04W28/18
Filed: 1999-10-12
Abstract: A wireless communication system selectively delays serviced data communications to produce a desired level of voice communications capacity.  The system first determines whether the wireless communication system has sufficient voice communications capacity. If it is determined that the wireless communication system has insufficient voice communications capacity, the system determines a data communications delay that is required to provide sufficient voice communications capacity. Based upon its determination, the system then selectively delays some or all of the data communications to create the sufficient voice communications capacity. In one operation, one data communication serviced by the wireless communication system is selectively delayed to create the sufficient voice communications capacity. In another operation, a plurality of data communications serviced by the wireless communication system are selectively delayed to create the sufficient voice communications capacity. When a plurality of data communications being serviced by the wireless communication system, some of the plurality of the data communications serviced by the wireless communication system are delayed by a first delay level and other of the data communications serviced are delayed by a second delay level.
