Patent CA-2327634-A1 (CA)
Title: Abrasive particles with metallurgically bonded metal coatings
Inventor: SHERMAN ANDREW J
IPC: C09K3/14
Filed: 2000-12-04
Abstract: An abrasive composite particle comprising a cubic abrasive core particle encapsulated within a deposit of hexagonal metallurgical bond forming material comprising at least about 50 volume percent rhenium, ruthenium, osmium or mixtures thereof. The metallurgical bonds serve to retain the core particle in a matrix/binder very strongly. Metallurgical bonds are formed by the encapsulating material taking into solution, at the interface with the cubic abrasive core particle, some element or compound from the abrasive particle such as, for example, carbon or cubic boron nitride, from the core particle. Chemical bonds are not formed between the abrasive particle and the deposit. Suitable abrasive core particles include diamond, cubic carbides, cubic borides, cubic nitrides, cubic oxides, and the like.  Conventional fabrication procedures such as chemical vapor deposition are employed to form the metallurgical bond forming deposit on the core particle. The composite abrasive particles are useful in forming articles according to conventional powdered metal processing operations. The articles so formed are useful for their hardness as well as their abrasiveness.

Title: Multi-wavelength lasers
Inventor: AHMADVAND NIMA
IPC: H01S3/083
Filed: 2001-05-23
Abstract: In this invention an optical gain element is used where a fraction of the optical output signal is passed through a periodic filter and fed back to the gain medium.  This configuration simply forms a multi-wavelength ring laser. The optical gain element provides the gain medium for the laser and the filter forces the laser to lase on the predetermined wavelengths. The periodic filter can simply be an asymmetric Mach-Zehnder Interferometer (MZI). It is known that asymmetric MZIs have an almost sinusoidal wavelength response where its period is a function of the length difference of the arms of the asymmetric MZI. Therefore, channel spacing may be controlled by changing the arms length difference in an Asymmetric MZI.

Title: Fast readout of multiple digital bit planes for display of greyscale images
Inventor: CROSSLAND WILLIAM ALDEN
IPC: H04N5/66
Filed: 1999-12-16
Abstract: In a method of signal processing for greyscale imaging in which weighted bitplanes corresponding to a greyscale image are stored as binary strings in sequential locations in a memory, in decreasing order of intended duration (weighting), a number of read passes equal to the number of weighted bitplanes are made from the set of stored bitplanes, each pass commencing with the highest order bitplanes and continuing along the stored bitplanes in sequence, the lengths of the sequences being varied and selected such that at the end of the said number of read passes each bit plane has been read out a plurality of times proportional to or equal to its duration (weighting). The method has utility in driving high speed liquid crystal matrix arrays particularly where each bitplane needs to be refreshed. A small ac potential may be applied to the array between writing steps.
