Patent CA-2371470-A1 (CA)
Title: High thrust turbocharger rotor with ball bearings
Inventor: HEILENBACH JAMES W
IPC: F02C7/06
Filed: 2002-02-11
Abstract: An improved turbocharger for railway locomotive sized engines includes, in a preferred embodiment, first and second axially spaced ball bearings supporting a rotor with the first bearing being a hybrid ceramic ball bearing mounted to accept both radial and axial loads acting on the shaft at the compressor end. The first bearing is mounted on a reduced diameter portion of the shaft, providing reduced bearing diameter to acceptably limit centrifugal loading of ceramic balls in the bearing against a surrounding bearing race.  The first bearing has dual rows of ceramic ball bearings mounted to share all axial thrust loads on the shaft. The second bearing is also a ball bearing.   Lubrication of the bearings is preferably by direct impingement on the inner race to minimize oil churning causing heating and power loss. Additional features and advantages are disclosed.

Inventor: SCOTT MICHAEL R
IPC: A61P31/04
Filed: 2000-05-24
Abstract: A method of sterilizing objects as well as the sterilized objects obtained from the method are disclosed. The method involves contacting an object such as a medical device to be reused with polycationic dendrimer under conditions which result in rendering a conformationally altered protein (e.g. a prion) non-infectious. A disinfecting agent or surgical scrub composition which comprises the dendrimers is also disclosed as are gelatin capsules treated with polycationic dendrimers.

Title: Gas recovery apparatus, method and cycle having a three chamber evacuation phase for improved natural gas production and down-hole liquid management
Inventor: REITZ DONALD D
IPC: E21B43/12
Filed: 2002-03-14
Abstract: Natural gas produced from a well by executing a multiple-phase gas recovery cycle which includes a phase during which a relatively lower evacuation pressure is applied within the entire well bore to assist in accumulating liquids at a well bottom. The relatively lower evacuation pressure augments the national earth formation pressure to produce natural gas and liquid more rapidly. The phases of the gas recovery cycle are also coordinated with the phase in which the relatively lower evacuation pressure is applied throughout the well to facilitate a greater natural gas production rate.
Patent CA-2378541-A1 (CA)
Title: Using of stokes law cement slurries for improved well cementation
Inventor: HABERMAN JOHN P
IPC: C09K8/46
Filed: 2002-04-04
Abstract: A method for providing lower than normal API Class cement slurries for use in oil well cementing is disclosed. Rather than the use of any conventional density extenders for hydraulic cement, such as bentonite, only plain water is added to the selected normal API Class slurry to extend its density. The use of cement retarders, cement accelerators, or friction reducers for these purposes, but not for density extension, is contemplated also.

IPC: H04B10/291
Filed: 2000-07-19
Abstract: A demultiplexer in a dispersion compensation system of the invention separat es an optical signal in a 1520-1620 nm band propagating through a first common transmission path into two bands, i.e., C band (1520-1565 nm) and L band (15 65- 162O nm). The demultiplexer then sends the optical signal in the C band and the optical signal in the L band to a first branch path and a second branch path, respectively. A first dispersion compensation device is provided in th e first common transmission path to compensate for dispersion in the C and L bands. A second dispersion compensation device is provided in the second branch path to compensate for dispersion in the L band if the dispersion compensation by the first dispersion compensation device is insufficient. It  is thus possible to sufficiently compensate for the dispersion of an optical  transmission path in a wide signal band.

Inventor: SWERIDUK CHRISTOPHER A
IPC: A61K9/20
Filed: 2000-09-26
Abstract: The present invention provides a method for preparing a spray-dried, compressible granular formulation for preparing pharmaceutical tablets in which essentially water-insoluble, acidic, amphoteric, and basic pharmaceutically active agents are converted to more water-soluble salts which are granulated with hydrolyzed cellulose, drug-containing slurries, the resulting granulations, capsules containing granulations, and pharmaceutical tablets compressed from such granules. In these formulation there is employed from 1% to 85% by weight of the pharmaceutically active agent and its salt form, from 5% to 99% of hydrolyzed cellulose, based on the dry weight of the granulation, and optionally, conventional granulation and/or tableting additives such as surfactants, disintegrants, and antiadherents/flow aids.  Said tablets have singificantly increased dissolution of the pharmaceutically active agent at the pH of the gastorintestinal tract in comparison with the unconverted free pharmaceutically active agent.

Title: Lateral steady acceleration simulation system for railway vehicle
Inventor: HASHIMOTO ATSUSHI
IPC: G01M7/02
Filed: 2001-06-25
Abstract: To provide a lateral steady acceleration simulation system for railway vehicle, which is capable of simulating a situation in which lateral steady acceleration is applied to a railway vehicle for a long period of time, while having a compact structure. In a riding quality simulation system of the invention, a control unit activates each of actuators (40), thereby making a simulated passenger room (10) roll. Then, the simulated passenger room (10) is gradually inclined, while a component force, along an inclined plane, of gravitational acceleration g, that is, a first reproductive acceleration G1 is generated depending on an angle of inclination .theta.. In this manner, a person riding on the simulated passenger room (10) bodily senses the first reproductive acceleration G1 by the roll. At the same time, the control unit moves the simulated passenger room 10, by means of a laterally moving device, in either of the left or right direction with acceleration G.  In this manner, the person riding on the simulated passenger room (10) bodily senses a second reproductive acceleration G2. As a result, the person riding on the simulated passenger room (10) bodily senses a combination of the first and second reproductive accelerations G1 and G2 as lateral steady acceleration on a railway.

Title: Polymeric compositions and articles with anisotropic light scattering and methods of making and using
Inventor: ZHOU ZHIMING
IPC: C09J7/38
Filed: 2001-12-18
Abstract: A polymeric composition includes a first polymeric material, for example, an adhesive material, and a second polymeric material disposed as a plurality of elongated structures within the first polymeric material. Each elongated structure has a major axis and the major axes are substantially aligned. The first polymeric material has an index of refraction that differs by at least 0.01 from an index of refraction of the second polymeric material. In some instances, a pressure sensitive adhesive material is selected as the first polymeric material. The orientation of the elongated structures and the difference in indices of refraction results in the polymeric composition scattering light asymmetrically. The polymeric composition is optionally disposed on a substrate and can be used, for example, to extract light from a light guide or to asymmetrically alter the viewing angle of a display.

Title: Self-ligating orthodontic brackets having a safety locking feature for ligation cover
Inventor: ABELS NORBERT
IPC: A61C7/28
Filed: 2001-09-11
Abstract: Self ligating orthodontic brackets include a bracket base, a ligation cover and a special safety locking feature that prevents inadvertent unlocking of the cover. This feature is provided by a ligation cover (150) hingedly attached to the base (144) by a film hinge (162), and a trapezoidal locking tongue (154) that is slidably received within a corresponding angled key way.  The movement of the locking tongue is restrained (154) in response to flexation by the cover (150). An arch wire (147) shortens the length of the cover (150) by causing it to bulge upward in the middle relative to the base (144). The surfaces (157, 159) defining the angled key way restrict movement of the locking tongue (154) so that it is necessarily pulled more tightly into the angled key way, resulting in a tighter locking connection between the cover (150) and the base (144).
