Title: A bond coating containing metallic compounds for a superalloy article
Inventor: RICKERBY DAVID STAFFORD
IPC: C23C14/06
Filed: 1996-11-30
Abstract: A multi-layer thermal barrier coating 42 for a superalloy article 40 comprises a metallic matrix coating 44 containing particles 46, a MCrAIY alloy bond coating 48 on the metallic matrix coating 44, a thin oxide layer 50 on the MCrAIY alloy bond coating 48 and a columnar grain ceramic thermal barrier coating 52. The metallic matrix coating 44 comprises a 80wt% nickel 20wt% chromium alloy. The particles 46 comprise suitable metallic compounds e.g. carbides, oxides, borides and nitrides which are selected such that they will react with harmful transition metal elements, for example titanium, tantalum and hafnium, in the superalloy substrate. One suitable compound is chromium carbide because the harmful transition metal elements will take part in an exchange reaction with the chromium in the chromium carbide to form a stable carbide of the harmful transition metal element. This reduces the amount of harmful elements in the superalloy reaching the oxide layer 50 and increases the service life of the thermal barrier coating 42 . In another embodiment the particles may be dispersed in the MCrAIY alloy bond coating which then constitutes the metallic matrix coating. On top of the matrix bond coating there may be disposed a platinum-group metal enriched aluminium containing alloy layer and then a layer of an aluminide of the platinum-group metal. The matrix coating may be applied by spraying.

Title: Active matrix display
Inventor: GILMOUR SANDRA
IPC: G09G3/36
Filed: 1997-04-30
Abstract: An active matrix light modulator, such as a thresholdless antiferroelectric active matrix liquid crystal display, comprises an active matrix of control elements 18 disposed at intersections of data lines and scan lines, and an array 10 of pixels which are selectively addressable by data and scan signals applied to the control elements 18 by a data driver 12 and a scan driver 14. Such addressing is controlled so that a voltage is applied to each pixel during a corresponding addressing frame by the application of data and scan signals to an associated one of the control elements 18 in order to select the optical level of the pixel for each frame, and bipolar switching is applied to control the voltage applied to the pixel during successive subframes such that, when one optical level is selected for the frame, a positive voltage is applied to the pixel during one subframe of the frame and a negative voltage of equal magnitude but opposite polarity is applied to the pixel during another subframe of the frame and, when another optical level is selected for the frame, an intermediate voltage (preferably zero voltage) is applied to the pixel during both of the subframes of the frame, so as to provide DC balancing within the frame. Because of such DC balancing within each frame, the required grey level within each frame is accurately reproduced and is substantially independent of the previous state of the pixel.

Title: Blow pin assembly for a rotary blow moulding machine
Inventor: WEBER LAWRENCE H
IPC: B29C49/04
Filed: 1999-03-15
Abstract: A blow pin assembly 34 for a rotary blow molding machine 10 having a carrousel 16 that supports a number of molds 24 located about the circumference of the carrousel 16. Each mold 24 includes a separate blow pin assembly 39 mounted on the mold clamp 28. The blow pin assemblies 34 each includes a base 42, a carriage 44 supported by the base 42, a sub-base 48 supported by the carriage 44, and a blow pin 36 mounted to the sub-base 48 for movement therewith. The carriage 44 moves the sub-base 48 and blow pin 36 linearly along a first path from a home position, in which the blow pin 36 is retracted away from the mold opening 26a, to an alignment position, in which the blow pin 36 is located directly above the mold opening 26a. The sub-base 48 then moves the blow pin 36 in a direction perpendicular to the first path from the alignment position into a mold-engaging position, in which the blow pin 36 is inserted into the mold opening 26a. This sequential, orthogonally-related motion allows the blow pin 36 to be retracted away from the mold opening 26a during the parison extrusion operation, yet permits the blow pin 36 to enter the mold opening 26a along a linear path that is coincident with the central axis CL of the mold 24. This motion permits pre-blowing of the blow pin 36 and helps minimize the opportunity for the blow pin 36 to catch and fold over the upper edge of the parison. The blow pin assembly can include a pair of stop members 86a, 86b (86a - figure 3 not shown) that positively engage each other when the blow pin 36 has reached its alignment position.

Title: Wideband optical service channel for wavelength division multiplexed networks
Inventor: BARNARD CHRIS
IPC: H04J14/02
Filed: 1999-07-13
Abstract: A method is described for wavelength-division multiplexed optical fiber networks whereby an unused portion of the optical spectrum is used to transmit OAM and P information internodally. An extra port of one or more of the optical multiplexers and demultiplexers accesses the unused portion of the optical spectrum. The method for the optical service channel avoids the requirement for ancillary filters so that adding and dropping the service channel does not increase the loss experienced in the wavelength-multiplexed signals.
