Title: Ionotropic gel lacking a gelling ionic entity, process for the preparation of such a gel and use thereof especially in a process for producing a sparkling wine
Inventor: RINN JEAN-CHARLES
IPC: C12G1/06
Filed: 1992-02-25
Abstract: IN THE    CANADIAN     PATENT AND TRADEMARK OFFICE     ABSTRACT OF THE DISCLOSURE         The  invention  relates  to  an  ionotropic  gel forming especially a fermentation biocatalyst.        This gel, in particular in the form of beads, is prepared from a material which can be  ionically gelled by means of an ionic gelling entity,  and is deficient  in  ionic  gelling  entity and  thus  has  an affinity for ions, in particular cations such as the calcium ion and the potassium ion.  In an advantageous embodiment,  this gel contains cells of yeasts or of fermentation microorganisms.        The invention is advantageous within the frame-work of the bottle fermentation process for wine, in particular champagne wine, for avoiding the crystalline precipitations  and  reducing  the  cloudiness  of  the sparkling wines obtained, and also within the framework of processes for the removal of heavy metals, enzymic processes or processes for the recognition, binding or purification of organic materials such as proteins or amino acids.

Title: Self calibrating dual range a/d converter
Inventor: BERNSTEIN LAWRENCE J
IPC: H03M1/14
Filed: 1992-06-08
Abstract: A dual range A/D converter includes a gain matching circuit (60) for balancing the upper end of the transfer curves of the level-dependent dual A/D signal paths of the converter so as to control crossover between the paths. One path (high gain path B) is provided with signal gain that is a nominal multiple of gain applied to the other path (low gain path A). A digital comparator (62) compares the digital code word output of flash A/D converters (12, 10) included in the respective paths, with the output from the high gain path being scaled down to correspond to the output from the low gain path. If a difference is detected, the upper ladder reference of the flash converter (10) in the low gain path (A) is adjusted until the respective gain difference becomes substantially an exact multiple. When this matching is combined with black level correction, which equalizes the lower end of the transfer curves, a fully self-calibrating dual range A/D converter is obtained.

Abstract: A method and apparatus is provided for dynamic distribution of a communication channel load of sectorized-antennae or omni-directional antennae of cell sites in a cellular radio communication system. The channel load is distributed by narrowing an antenna (102) beamwidth of an overloaded sector of a cell site (100) and widening an antenna (104) beamwidth of an adjacent sector of the cell site (100). In an alternative embodiment, the channel load is distributed by reducing power of an antenna (124) of a cell site (120) which is adjacent to an overloaded cell site (100). Alternatively, the channel load is distributed by increasing power of an antenna (118) of a cell site (116) which is adjacent to an overloaded cell site (100). Subsequent to the channel load distribution, each of the subscriber units in the overloaded (100) and adjacent cell sites (116, 120) are handed off to the particular cell site which is best able to service the subscriber units.

IPC: G02B3/00
Filed: 1993-07-08
Abstract: A method is provided for producing a light emitting device having a chip with a front surface, a rear surface, an electrode formed on the front surface, a narrow emanating region near the front surface, and a spherical lens fixed to the rear surface for converging light beams. The method includes the steps of grinding a rear surface of a wafer until the thickness of the wafer is reduced to a value d2, wherein the d2 is determined from the equation d2=d1-r, wherein d1 is the distance between the centre of the spherical lens and the centre of the emanating region and r is the radius of the spherical lens. Another electrode is formed on the near surface of the wafer in a form which allows light to emanate therethrough. The wafer with a flat rear surface is divided into a plurality of individual device chips, each chip having an emanating region and electrodes. A device chip is mounted on a workpiece at the rear surface of the device chip. A current is supplied to the device chip for emitting light through the rear surface of the device chip. The pattern of the emanating region is observed by a TV camera which is connected to a computer. The centre of the emanating region is determined in a two-dimensional coordinate which is defined on the rear surface of the device chip. The coordinates of the centre of the emanating region is memorized. Adhesive is supplied on the rear surface of the device chip. A spherical lens is carried to a spot of the memorized coordinates above the centre of the emanating region. The adhesive is then hardened to fix the lens on the rear surface of the device chip without a gap between the lens and the rear surface of the device chip.
