Patent CA-2287197-A1 (CA)
Inventor: REAMES GARY
IPC: B29C70/76
Filed: 1999-10-25
Abstract: The method of the present invention is performed by providing a glass sheet having first and second opposite surfaces merging with each other along a peripheral ground angled surface setting-off with the glass sheet first surface an included angle substantially greater than normal. The glass sheet is placed in a mold having opposing cavity portions which collectively define a cavity including a peripheral edge cavity portion defined in part by a cavity defining surface which lies in the plane of the glass sheet first surface when the mold is closed. The mold is then closed such that the cavity defining surface and the glass sheet round angled surface set-off and angled complementary to the included angle and with the glass sheet per surface abutting the cavity defining surface inboard of the glass sheet ground angled surface. Polymeric/copolymeric synthetic plastic material is injected into the peripheral cavity portion to completely encapsulate the glass sheet periphery with a border, frame or encapsulation having a first exterior surface coplanar with the glass sheet first surface whereby the latter two surfaces are "flush-to-front" and the glass sheet periphery is in undercut interlocked relationship with the injection molded border.

Title: Device and method for controlling powers of orthogonal channel and quasi-orthogonal channel in cdma communication system
Inventor: MOON HI CHAN
IPC: H04W52/24
Filed: 1999-03-26
Abstract: A power control device for a CDMA communication system using different kinds of spreading codes. In the power control device for a base station device, a first channel generator generates a first channel signal by spreading first input data (DATA1) with an orthogonal code and a second channel generator generates a second channel signal by spreading second input data (DATA2) with a quasi-orthogonal code. The second channel signal has a gain higher than that of the first channel signal. A first gain controller (17) controls power of the first channel signal and a second gain controller (18) controls power of the second channel signal. An adder (20) adds the first channel signal to the second channel signal, and a spreader (21) spreads a signal output from the adder with a pseudo-random noise (PN) code. The base station transmits a response request message to a mobile station via the second channel, and retransmits the response request message after increasing a transmission power of the second channel when a response message is not received from the mobile station.

Title: Apparatus and method for monitoring shaft cracking or incipient pinion slip in a geared system
Inventor: SRIBAR ROK
IPC: G06F19/00
Filed: 1999-11-18
Abstract: A diagnostic technique for monitoring shaft cracking or incipient pinion slip involves monitoring a shift in a characteristic natural frequency of an operating system such as a geared system of a locomotive. The technique involves monitoring a shift in the characteristic natural frequency or resonance of a shaft for detecting shaft cracking. The technique also involves monitoring a shift in the characteristic natural frequency of one or more assemblies of the operating system which include a pinion and detecting a shift in the one or more characteristic natural frequencies of the assemblies. A vibration sensor or measurement of current changes of a motor of the operating system can be used to detect vibrations to monitor the characteristic natural frequencies. Torsional oscillations or measurement of current and voltage changes of a motor of the operating system, can also be used to monitor the characteristic natural frequencies.

Patent CA-2292114-A1 (CA)
Inventor: DALY JEFFERY E
IPC: F16J15/34
Filed: 1999-12-13
Abstract: The present invention is a self adjusting, volume balanced, single energizer rigid face seal for rolling cutter drill bits with floating journal bearings. Volume balancing is accomplished by utilizing a floating static seal between the rigid face seal ring and the bearing shaft. This floating static seal ring is moved axially within a annular groove by the volume pulses caused by the axial play of the cutter when in operation. At one end of the annular groove the geometry of the rigid seal ring and bearing shaft are set such that the seal assembly achieves volume balance when the bearing is running on its OD. If the bearing is running on its OD, the floating static seal will move from where ever it is in the annular groove by the volume pulses until it reaches the balance volume position.

Patent CA-2294981-A1 (CA)
Title: Novel formulations of pharmacological agents, methods for the preparation thereof and methods for the use thereof
Inventor: DESAI NEIL P
IPC: A61K31/335
Filed: 1998-06-26
Abstract: In accordance with the present invention, there are provided compositions and methods useful for the in vivo delivery of substantially water insoluble pharmacologically active agents (such as the anticancer drug paclitaxel) in which the pharmacologically active agent is delivered in the form of suspended particles coated with protein (which acts as a stabilizing agent). In particular, protein and pharmacologically active agent in a biocompatible dispersing medium are subjected to high shear, in the absence of any conventional surfactants, and also in the absence of any polymeric core material for the particles. The procedure yields particles with a diameter of less than about 1 micron. The use of specific composition and preparation conditions (e.g., addition of a polar solvent to the organic phase), and careful selection of the proper organic phase and phase fraction, enables the reproducible production of unusually small nanoparticles of less than 200 nm diameter, which can be sterile-filtered. The particulate system produced according to the invention can be converted into a redispersible dry powder comprising nanoparticles of water-insoluble drug coated with a protein, and free protein to which molecules of the pharmacological agent are bound. This results in a unique delivery system, in which part of the pharmacologically active agent is readily bioavailable (in the form of molecules bound to the protein), and part of the agent is present within particles without any polymeric matrix therein.

Title: Stable cosmetic compositions with different ph emulsions
Inventor: MUKHERJEE SURAJIT
IPC: C09K23/00
Filed: 1998-10-06
Abstract: The inventive compositions contain an oil-in-water and a water-in-oil emulsion, each buffered to a specific pH, so that the difference in pH values of the two emulsions is at least two units. The molecular mixing is minimized by selecting suitable oil and oil phase in a water-in-oil emulsion. The change in pH is further minimized by buffering each emulsion. The particular advantage of the inventive compositions is the ability to separate within a single composition, with minimal intermixing, active compounds which require different pH  environments for stability and/or optimum efficacy.
