Abstract: L'invention porte sur des procédés de formation d'un composite fibreux absorbant contenant un matériau absorbant dispersé en bandes longitudinales dans le composite. Lesdits procédés consistent à déposer une pâte fibreuse sur un support poreux (202, 204), de manière à former une toile puis à disposer ou injecter un matériau absorbant dans la toile sur sa largeur pour obtenir une toile (126) présentant des bandes absorbantes longitudinales, ce qui après séchage donne un composite absorbant cannelé. Dans l'une des exécutions, on recourt à un dépôt humide, et dans l'autre, à l'expansion. Lesdits procédés sont de préférence des procédés de formation à deux toiles.

Title: Thrust bearing
Inventor: FERGUSON JAMES HAROLD
IPC: F16C17/04
Filed: 2000-10-26
Abstract: A thrust bearing for a rotating machine has a rotating ring and a bearing shoe for use in a non-filled oil chamber that permits oil flow through the bearing shoe. The oil flows out a leading recessed groove in the bearing shoe and across the bearing shoe surface. This permits for the oil flow to cool the bearing shoe and maintain lubrication between the bearing shoe and the rotating ring. Further, the non-filled oil chamber acts more as an oil collection chamber which provides two distinct advantages. One advantage is a reduction in bearing losses not present due to the elimination of swirling of the oil bath. The other advantage is one of servicing by the ability to inspect the bearings and all oil conduit connections without being encumbered by oil partially covering or surrounding the bearing shoe. The thrust bearing has an oil reservoir located below the non-filled oil chamber into which oil drains from the non-filled oil chamber and an oil cooling and circulating system comprising a pump, heat exchanger and conduit connectors connected to each oil inlet for circulating oil drained into the oil reservoir through the heat exchanger into the flexible hoses and back into the bearing shoes. Further, the thrust bearing shoe has a secondary oil inlet adjacent the leading edge of the bearing shoe providing a safety back-up lubrication source.

Title: Partial delegation of complex olap queries with application to zero suppression condition evaluation
Inventor: LEATHERS BURTON
IPC: G06F16/28
Filed: 2000-12-29
Abstract: The present invention introduces a mechanism to partition the processing work required on data from a variety of proprietary OLAP data sources in such a way that as much as possible of the processing can be carried out by the OLAP data source, thereby improving the efficiency of the delegated portion of the operations, and making more effective use of the overall processing power of the computing facilities. By decomposing the required high level expressions into sub-expressions to be applied to data elements some part of the expressions can be evaluated by the OLAP data source. The results of these sub-expressions are combined by the OLAP data engine to produce the same result as the original full expression. 'Rows' and 'columns' of the original cross-tabulation formed from the data are classified as either simple - meaning the expression can be processed at the OLAP data source or complex - meaning such expressions cannot be computed at the OLAP data source. That segment of the cross- tabulation comprising Simple rows and Simple columns can be processed in terms of the high level operation directly by one or more OLAP data sources.

Abstract: A method for operating a TEM cell to determine the characteristics of a radiation source in a circuit. The circuit is placed in the TEM cell such that the relative orientation of the circuit and the TEM cell is measurable. The TEM cell provides an output signal indicative of the energy radiated by the circuit when the circuit is operated in the TEM cell. The output signal of the TEM cell is measured for at least 6 different relative orientations of the circuit and the TEM cell. The electric and magnetic dipole moments of a radiation source having an orientation and physical dimension associated therewith are determined from the measured output signals. The electric and magnetic dipole moments determined from the measured output values are compared to moments predicted by each of a plurality of antenna types to provide an estimate of the orientation of the radiation source relative to the circuit. In addition, embodiments of the present invention may also measure the output signal of the TEM cell as a function of frequency for at least one of the different relative orientations. This information may be used to determine a physical dimension associated with the radiation source. In one embodiment of the present invention, the measured output signal is evaluated as a harmonic series. In another embodiment of the present invention, the output signal of the TEM cell at a predetermined frequency is measured as a function of time to determine the modulation of the output signal.

Title: Method for early diagnosis of, and determination of prognosis in, cancer
Inventor: CARSON DENNIS A
IPC: C12Q1/68
Filed: 1999-06-21
Abstract: The invention provides a method for diagnosis of, and determining a prognosi s for, cancer causatively associated with derangements of chromosome 9p21. Underlying the invention is the discovery that such derangements have their genesis in deletions occurring centromeric to STS 3.21, most often including  breakpoints in exon 8 and/or between exons 4 and 5 of the gene which codes f or methylthioadenosine phosphorylase. As the cancer and tumor development advance, deletions in 9p21 progress centromerically from the genesis point toward the gene encoding p16. Thus, the method of the invention is performed  by determining whether (a) portions of the 9p21 region including and telomer ic to STS 3.21 are deleted; and (b) portions of the 9p21 region centromeric to STS 3.21 are deleted; wherein a positive finding in step (a) and a negative finding in step (b) are indicative of a cancer in an early stage of tumor development and a positive finding in step (b) is indicative of a cancer in an advanced stage of tumor development.

Abstract: A dog training lead includes first and second sound-producing strips or members. An elastic member is interposed between the first and second strips, and is connected at the opposite ends thereof to and in a coaxial manner with the lead. The elastic member is dimensioned to bias the terminal ends of the first and second strips toward each other to thereby place the central portions of the first and second strips in a first or laterally spaced-apart relationship relative to each other. Upon application of a sharp, corrective pull on the lead by a trainer, the elastic member elongates toward a second position, and this results in the central portions of the first and second strips contacting each other with sufficient speed and force to emit a sharp "snap" sound.

Title: Improved steam generating apparatus and method of controlling the same
Inventor: ALTMAN MITCHELL
IPC: A61H33/06
Filed: 1995-08-04
Abstract: Improved steam generating apparatus in the form of a thin, compact generally-self-contained wall-mountable fixture. The fixture includes an upright front face section of porcelain or the like for being mounted in the wall of a shower or other enclosed steam room. The fixture further includes a frame that is fixed to the rear of the face section and supports a closed steam tank or boiler. A steam line delivers live steam from the boiler into the steam room. An improved steam head delivers the steam safely and with minimum noise. The fixture may also include a mirror and be mounted so that the mirror is face height of a standing user. The mirror is positioned adjacent to the boiler so that heat radiated from the boiler warms the mirror and inhibits it becoming fogged over by the steam in the room. The fixture also includes an electrical control system that is operable by the user from inside the steam room. The control system automatically maintains the user-preselected steam room temperature by regulating the power to the boiler so that steam is generated without interruption and after equilibrium is reached there are no noticeable changes in the room temperature.
