Abstract: Un procédé et un dispositif permettent de décontaminer et de détoxiquer des matières, notamment des céréales et d'autres graines alimentaires et/ou fourragères. Les matières ou les céréales sont exposées à un traitement aux ultra-sons dans un milieu aqueux. On a découvert qu'un tel traitement entraîne de manière surprenante une décontamination ou détoxication efficace du produit, sans que l'apparence, le goût ou la valeur nutritive du produit décontaminé, surtout des produits céréaliers, ne soient affectés.

Abstract: A valve device which can reliably seal water even after a long continuous use. It has a valve seat made of a hard ceramic having a fluid passage and a valve body made of a self-lubricating polyphenylene sulfide resin and slidably put on the valve seat. Inlet passages are formed in the valve body. The surface of the valve body to be brought into sliding contact with the valve seat is lapped into a flat or crowned smooth surface after swelling the valve body with liquid. Otherwise, the valve seat and the valve body are made of synthetic resins that show no adhesion to each other. The base and the valve seat may be integrally formed. Also, elastic packings may be provided on the end face of the base so as to protrude into the bottom openings of the inlet passages. Small-dimater flanged rings are fixed in position by the elastic packings.

Abstract: A folded, magnifying, front projection arrangement for video displays includes a video image source, such as a flat panel display unit out of the user's field of view, projects its image onto a concave mirror also out of the user's field of view. The video image source is maintained off-axis with respect to the optic axis of the concave mirror and at a distance from the concave mirror between one and two times the distance from the concave mirror to its principal focal surface, which would be the principal focal plane if the concave mirror were a spherical or a parabolic mirror. The concave mirror, in turn, reflects and focuses the light from the video image source onto a projection screen, within the user's field of view, resulting in a magnified image. The distortion of the projected image that would otherwise result from off axis projection is compensated for by maintaining the plane of the video image source at a non-perpendicular angle to the optic axis of the mirror. As a result, the image formed on the projection screen is undistorted and in focus across its full width and breadth. Since the projection screen is not an active element, a small aperture, or hole, can easily be cut through it so that a video camera, for capturing the image of the viewer of the screen, may be positioned behind it.  The image resulting from such camera placement provides good eye contact to a remote party viewing the image.
Patent CA-2110106-C (CA)
Inventor: ROEHRICH ROLAND LOUIS
IPC: F25B19/00
Filed: 1993-11-26
Granted: 2003-01-21
Abstract: Methods and apparatus for controlling a condi-tioned space to a predetermined set point temperature, utilizing a supply of cryogen. Cryogen is drawn from the supply in a flow path to provide a cooling made via a heat exchanger disposed in the flow path. A vapor motor in the flow path, downstream from the heat exchanger, drives a fan which moves air between the conditioned space and the heat exchanger. Heat is applied to the cryogen downstream from the heat exchanger, after all cooling modes have been performed, to provide the desired fan horsepower, without interfering with a coating cycle. A by-pass flow path selectively directs cryogen directly to the vapor motor, by-passing the heat exchanger, to provide air circulation in the conditioned space when the temperature of the conditioned space is satisfied.

Title: Image coding method and apparatus therefor
Inventor: JEON JONG-GU
IPC: H04N19/91
Filed: 1994-10-14
Granted: 1999-07-20
Abstract: An image coding method includes the steps of producing a complexity normalizing value of respective macro blocks based on a complexity in a space domain with regard to an input image, producing a zero coefficient sum by performing a discrete cosine transform operation on the input image and counting the discrete cosine transform coefficients from -1 to +1, producing a zero coefficient normalizing value for respective macro blocks in accordance with the zero coefficient sum; producing a transient weight for respective macro blocks in accordance with the zero coefficient sum and a predetermined compression ratio, and summing the complexity normalizing value, the zero coefficient normalizing value and the transient weight so as to produce the scale factor. The quantization step size of the discrete cosine transform coefficients is controlled in a macro block unit in accordance with the scale factor. Thus, image frames having various complexities can be encoded at a constant bit rate with no deterioration of the image.
