Patent CA-2618502-A1 (CA)
Title: Vehicle wheel
Inventor: FUJITA MASAYUKI
IPC: B60B1/06
Filed: 2008-01-24
Abstract: To provide a vehicle wheel having improved drainability of water entering a hollow portion. A rear wheel includes a hub portion, multiple spoke portions and a rim portion. The hub portion is provided with holes formed on an outer peripheral wall to be connected to a hollow portion. Two water-discharge holes are formed in a tip end part of each of the spoke portions and a wall of each of spoke portions is thickened only in the tip end part. The hollow portions of the spoke portions are formed to be connected to the hollow portion. By forming the water-discharge holes, drainability of water entering the hollow portion can be improved. Moreover, by thickening a wall only of the tip end part where the water-discharge holes are formed, stiffness of the spoke portions can be ensured.

Title: Multi-stage receiver for wireless communication
Inventor: JOETTEN CHRISTOPH ARNOLD
IPC: H04B1/707
Filed: 2006-11-30
Abstract: Techniques for receiving a MIMO transmission are described. A receiver processes received data from multiple receive antennas in multiple stages. A  first stage performs front-end filtering/equalization on the received data with a front-end filter to process non on-time signal components in the multiple received signals. A second stage processes the filtered data with one or more combiner matrices to combine on-time signal components for multiple transmitted signals. For a MIMO-CDM transmission, a single front-end filter may be used for all channelization codes, and a different combiner matrix may be used for each channelization code. Partitioning the receiver processing into multiple stages simplifies derivation of the front-end filter and combiner matrices while achieving good performance. The front-end filter and combiner matrices may be updated separately at the same or different rates.

Title: Processing of interference on a radiofrequency signal by power inversion
Inventor: RENARD ALAIN
IPC: H04B15/00
Filed: 2008-05-15
Abstract: The invention relates to a radiofrequency receiver, notably for satellite positioning applications, needing to operate in an environment where interference is dense, notably when it involves pulses transmitted by DME beacons. Below the useful signal suppression threshold, amplitude or power are inverted to improve the dynamic interference response time. Advantageously, the useful signal suppression threshold and the set point power or amplitude are determined by analyzing the amplitude or power probability density function in its part enriched with low amplitude/power samples.
Patent CA-2631855-A1 (CA)
Inventor: REYNOLDS BRUCE
IPC: C10G45/00
Filed: 2006-12-08
Abstract: A new residuum full hydroconversion slurry reactor system has been developed that allows the catalyst, unconverted oil and converted oil to circulate in a continuous mixture throughout an entire reactor with no confinement of the mixture. The mixture is partially separated in between the reactors to remove only the converted oil while permitting the unconverted oil and the slurry catalyst to continue on into the next sequential reactor where a portion of the unconverted oil is converted to lower boiling point hydrocarbons, once again creating a mixture of unconverted oil, converted oil, and slurry catalyst. Further hydroprocessing may occur in additional reactors, fully converting the oil. The oil may alternately be partially converted, leaving a highly concentrated catalyst in unconverted oil which can be recycled directly to the first reactor. Fully converted oil can be subsequently hydrofinished for the nearly complete removal of hetoroatoms such as sulfur and nitrogen.

IPC: F16B37/10
Filed: 2008-05-30
Abstract: A tensioner for tensioning foundation bolts generally used in securing large utility towers is provided. The tensioner generally comprises a hollow outer body through which the foundation bolt can extend. The lower end of the body, which is adapted to abut onto the foundation surface from which the bolt extends, is provided with an opening allowing access to a foundation nut threaded onto the foundation bolt. The upper end of the outer body slidingly receives an inner body with which it defines an annular hydraulic piston, the inner body being configured with a seat portion for receiving and engaging a split nut mounted to the foundation bolt. Upon providing hydraulic fluid to the tensioner, the hydraulic piston urges the split nut, engaged to the foundation bolt, upwardly, thereby tensioning the foundation bolt. The load in the bolt is then maintained by threading down the foundation nut until it abuts onto the foundation surface.

Inventor: GIACOLO ROBERT
IPC: B25G3/00
Filed: 2008-10-31
Abstract: A cleaning implement that includes a connector for connecting a handle to a base block. The connector prevents the handle from rotating relative to the base block and, thus, the connector prevents the handle from unscrewing or otherwise loosening or disconnecting from the base block. The base block can include a headpiece supported between oppositely arranged shoulders, a generally cylindrical flange projecting from the headpiece, and a generally cylindrical opening extending through the cylindrical flange. A slot may be formed in an inner surface of the cylindrical flange. A ferrule that can have a generally dovetail-shaped projection provided on its outer surface can be secured to an end of the handle. The projection and the slot can form a joint when the handle is connected to the base block. This joint substantially prevents the handle from rotating relative to the base block.

IPC: A61M11/00
Filed: 2007-04-20
Abstract: A fluid container of the invention has a container body provided with a shoulder and a sidewall that extend between an upper opening and a lower opening. The fluid container has a spacer provided adjacent to the shoulder of the container body. Further, a slide valve and a bottom cover are placed in the container body. The slide valve is liquid-tightly slidable along the inner surface of the sidewall of the container body and forms a fluid holding container space between itself and the sidewall of the container body. The bottom cover covers the lower opening of the container body. The spacer and the slide valve have a spacer surface and a valve surface, respectively, which face to each other, and the spacer surface and the valve surface are tilted at an angle in the range from 5 degrees to 30 degrees relative to a horizontal plane. Accordingly, an airless fluid dispensing system using the fluid container reliably prevents a small amount of air from remaining in the container body during fluid filling and can dispense a predetermined amount of fluid without unnecessary pumping operation before use.

Title: Process and system for cooking cheese with a substantially invariable energy transfer
Inventor: EJNIK STEVE
IPC: A23C19/00
Filed: 2007-08-30
Abstract: A process for transferring energy to the contents of a vat. An embodiment transfers an amount of heat energy needed to heat cheese curd and whey inside the vat according to a specified time and temperature. An energy substrate, such as steam and/or water, carries heat energy to a vat jacket. The embodiment calculates the total process energy required to be transferred to the vat contents to cook the cheese in accordance with a recipe. The total process energy is a function of the energy input to the vat minus the energy output from the vat. Small losses of energy from the vat to the atmosphere occur. These small losses are accounted for by use of historical efficiency data for each vat. The historical efficiency is continuously monitored and any deviation from the historical efficiency is factored into the energy transfer calculation for subsequent cheese batches.
