Title: Gas turbine split ring
Inventor: KATAOKA MASAHITO
IPC: F01D25/12
Filed: 2000-03-01
Abstract: In gas turbine split rings, end faces having bent surfaces are formed in flanges. Adjoining split rings are coupled together with a groove therebetween to form a cylindrical split ring. Notches are formed in the flanges. These notches are sealed by inserting a seal plate into the notches of adjoining split rings. A hole for passing cooling air is drilled obliquely in the flange. Cooling air is allowed to flow out along the direction of rotation (of the turbine) . This cooling air cools the outlet of the groove due to the effect of film cooling. Because of such cooling, high temperature gas is prevented from staying in this area, cooling effect is enhanced, and hence burning of the end portions can be prevented.

Title: Optically based on-line fiber monitoring system with drift compensation
Inventor: BRIEFER DENNIS K
IPC: G01B11/10
Filed: 1998-12-10
Abstract: Optical transmissivity-dependent parameters (90) including yarn denier (20) are monitored on-line in real-time with a preferably microprocessor-controlled high frequency modulated-demodulated optically-based system. A periodically driven LED (100) outputs preferably collimated light signal (120) and is spaced-apart from an array of preferably identical photodetector ("PD") diodes (110A-C) that will track one another. The yarn (20) is spaced between one of the PDs and yarn characteristics can affect PD-received light. A first PD (110A) output feedback to the LED driver to compensate the system against factors affecting LED driver to compensate the system against factors affecting LED transmission and PD light reception. A second PD  (110B) output is coupled to a fraction of the drive signal to enhance dynamic range. This signal is amplified, AC-coupled, sample-and-held during a stable active portion of the LED drive signal to demodulate the relevant signal. The digitized sampled held magnitude enables a CPU to provide denier and other yarn characteristics measurement data. A third PD (110C) helps self-calibrate the system.
Patent CA-2317239-A1 (CA)
Inventor: HICKEY JOHN L
IPC: B05D7/24
Filed: 2000-08-30
Abstract: A method for applying a coating of a low friction material to either or both of a pair of components that are adapted to slidably engage one another, such as a pair of splined members in a slip joint for use in a vehicular driveshaft assembly.  The low friction coating material is preferably formed from a mixture of at least two substances having differing melting temperatures, wherein the first substance (nylon, for example) has a melting temperature that is lower than the melting temperature of the second substance (polytetrafluoroethylene, for example). Initially, the component is heated to a temperature that is greater than the melting temperature of the first substance, but less than the melting temperature of the second substance.  Then, the coating is applied to the heated component by dipping the component into a tank containing the mixture of the first and second substances. The first substance of the coating melts upon contacting the heated component, and adheres to the heated component. Although the second substance of the coating does not melt, the first substance of the coating carries the second substance of the coating and, thus, supports the second substance of the coating relative to the heated component. The low friction coating material can then be cooled and shaped in a die or other mechanism as desired.
