Abstract: When scarfing the end portion of a plate-like material with irregular deformations or undulations, such as distortions, undulations and warps, the undulations are successively corrected flat and the flattened end portion is scarfed by a rotary cutter to form a highly precise scarfed surface. When the end portion of the plate-like material 3 is scarfed by the rotary cutter 5, the pressing member 11 presses, while the cutting operation proceeds, at least a part of the surface of at least that portion of the plate-like material 3 which is to be cut away as a chip 17 at a position near the blades 5b of the rotary cutter on a downstream side of the rotary cutter with respect to a rotary cutter movement direction, the surface of the plate-like material 3 pressed by the pressing member 11 being opposite the other surface held in contact with the cutter receiving table 7.

Inventor: BIRKETT NEIL
IPC: H03D3/24
Filed: 1999-10-04
Abstract: A digital demodulator which coherently demodulates a low-IF or zero-IF complex signal using a complex-valued phase-locked loop (CPPL). The CPPL includes a numerical controlled oscillator, four multipliers and two combiners to provide independent phase/frequency and amplitude outputs. The CPLL exhibits in first order PLL dynamics without a loop filter in the feedback loop to the NCO. However a filter with one or more poles may be included in the feedback circuit to exhibit 2 nd or higher order PLL dynamics. The CPLL allows coherent demodulation of extremely low FM modulation indexes whereby the incoming frequency drift may be larger than the frequency deviation. It can also be used to coherently demodulate signals which have combined amplitude and phase characteristics.

Abstract: La présente invention concerne de nouveaux procédés de fabrication et d'utilisation de composés et d'ensembles de nouveaux .alpha.-cétoamides, et les ensembles et les composés fabriqués selon ces procédés. Ces nouveaux composés sont des inhibiteurs potentiels d'enzymes protéolytiques, en particulier de cystéine protéases telles que la cruzaïne. L'application de ces nouveaux procédés a conduit à l'identification d'un certain nombre de nouveaux inhibiteurs, parmi un ensemble d'environ 38000 dérivés de .alpha.-cétoamide à activité spécifique contre trois cystéine protéases: la cruzaïne, la papaïne et la cathepsine B. Ces composés et d'autres composés identifiés par les procédés ci-dessus peuvent être utilisés, par exemple, dans la mise au point d'agents pharmaceutiques pour le traitement de maladies (par exemple, la maladie de Chagas) associées à ces protéases. Du fait que les composés concernés ont une activité spécifique pour la cruzaïne, la papaïne et la cathepsine B, lesdits procédés peuvent également être utilisés pour identifier des inhibiteurs d'autre protéases.

Patent CA-2289756-A1 (CA)
Inventor: CHEN JUN
IPC: B01J20/26
Filed: 1998-05-08
Abstract: A superporous hydrogel composite is formed by polymerizing one or more ethylenically-unsaturated monomers, and a multiolefinic cross-linking agent, in the presence of particles of a disintegrant and a blowing agent. The disintegrant, which rapidly absorbs water, serves to greatly increase the mechanical strength of the superporous hydrogel and significantly shortens the time required to absorb water and swell. Superporous hydrogel composites prepared by this method have an average pore size in the range of 10 µm to 3,000 µm. Preferred particles of disintegrant include natural and synthetic charged polymers, such as cross-linked sodium carboxymethylcellulose, cross-linked sodium starch glycolate, and cross-linked polyvinylpyrrolidone. The blowing agent is preferably a compound that releases gas bubbles upon acidification, such as NaHCO3. Improved hydrogel composites formed without a blowing agent are also provided.

Patent CA-2305655-A1 (CA)
Inventor: EBENSPERGER CHRISTOPH
IPC: A61K35/76
Filed: 1999-05-25
Abstract: The invention relates to vectors for cancer therapy which as a result of genetic differences between normal and transformed cells selectively eliminate the latter. This is made possible by integrating a sequence-specific recombinase into a viral or non-viral expression vector, whose expression is controlled by a transcription factor which has mutated in tumour cells and is therefore inactive, as well as by a suicide gene which is flanked by at least one recombinase-specific target sequence. Through the transcription-factor-mediated activation of the sequence-specific recombinase the vector is eliminated from untransformed cells together with the suicide gene. The vector is, however, not eliminated from tumour cells in which the transcription factor is not active and expresses the suicide gene in said cells. After contact with a corresponding prodrug these cells are selectively killed off.
