Patent CA-2265681-A1 (CA)
Inventor: DENNEY DENYS
IPC: B26D3/28
Filed: 1998-07-23
Abstract: Methods for continuously shaping a compressible or cellular polymer material, such as polyurethane foam, by cutting portions of the material from a surface of one or more slabs of material (180) including (a) compressing one or more slabs of cellular material between a pair of compression rollers (146, 146a) and two moving patterned platforms (132, 132a) interposed between the compression rollers, and (b) transversely cutting the slab or slabs with a blade or blades (76) just as the cellular material emerges from between the compression rollers. At least one of the moving patterned platforms, preferably an endless belt, defines a recess or pattern of recesses. When a slab or slabs of material are fed and compressed between the compression rollers, a portion of the material from one side of the slab or slabs fills the recess or recesses in one of the moving patterned belts. The blade then transversely cuts the cellular material.

Title: Characterization of fluid misting
Inventor: TURCHIN HENRY
IPC: G01N33/28
Filed: 1998-10-29
Abstract: A method and apparatus for measuring a misting property of fluids, the method and apparatus simulating mist generation of fluids in machining processes.  Fluid is supplied to mist generating means in an enclosure and energy input to the fluid by the mist generating means is controlled. Mist laden gas flows from the vicinity of mist generation to a mist concentration measuring means.  Droplets of relatively large mass are removed from the mist prior to the flow of gas reaching the mist concentration measuring means.

Patent CA-2295869-A1 (CA)
Inventor: PICCALUGA PIERRE
IPC: H04R3/04
Filed: 1998-07-06
Abstract: The invention concerns a method which consists in using digital sampling of a live sound recording or of an original sound medium, which is copied then formatted into a multiple reproduction of the original sampling. In order to observe the original time base, the multiple reproduction of copies, leads to the multiple reproduction of the sampling speed of the new digital signal. The quantization parameter can be identical to the original, or be subjected to value scaling, or be in reciprocal value. An apparatus formatting digital audio signal acquires a reference sampling from a digital decoder, then multiplies its data by adjustable independent samplers managed by a common clock. A relay programs the regular and cyclical activities of the samplers, determining a new digital sound signal. Said signal can be smoothed for analog use by fragile transducers. This formatting process adapted for acoustic transducers, can be used for recording and as audio signal software for transferring sound data.

Title: Electro-optic compound waveguide modulator
Inventor: MCCALLION KEVIN J
IPC: G02F1/01
Filed: 1998-01-20
Abstract: An electro-optic modulator is disclosed in the form of a compound waveguide device (10) having a channel waveguide (60, 160, 260) in optical proximity to an elongate waveguide (30) propagating an optical signal therein. The channel waveguide (60, 160, 260) includes a coupling surface through which optical energy is evanescently coupled to or from the optical signal propagating in the elongate waveguide (30). The channel waveguide (60, 160, 260) is shaped to confine distribution of the optical energy therein along axes transverse to the axis of propagation of the optical energy. Transverse diffraction of the optical energy within the channel waveguide (60, 160, 260) is thereby limited.  The channel waveguide (60, 160, 260) is formed from an electro-optically active material, and modulation of the optical signal propagating in the elongate waveguide is effected using the evanescent coupling effect between the two waveguides. In one embodiment, the elongate waveguide (30) is a side-polished fiber-optic waveguide.

Title: A novel method for the integration of foreign dna into eukaryotic genomes
Inventor: GORDON-KAMM WILLIAM J
IPC: C12N15/82
Filed: 1998-11-17
Abstract: Compositions and methods for introducing a DNA of interest into a genomic target site are provided. In particular, the methods and compositions involve the use of a combination of target sites for two site specific recombinases and expression of a chimeric recobminase with dual target site specificity. Thus, the compositions comprise novel site-specific recombinases with specificities to multiple target sites, and nucleotide sequences and expression cassettes encoding these recombinases or target sites. The methods involve transforming a eukaryotic cell having target sites for the novel recombinase with a DNA  of interest that is flanked by corresponding target sites. Expression of the recombinase results in integration of the DNA of interest into the genome of the cell. The compositions and methods of the invention have use in the construction of stably transformed eukaryotic cells, and in particular, plant cells. The methods result in the efficient targeted genomic intergration of DNA by site-specific recombination.
