Abstract: L'invention concerne une méthode qui est à la fois simple, économique et très efficace pour compléter la finition d'un panneau de type "moulé" présentant une surface plane sur laquelle une feuille de recouvrement est appliquée et collée, ce panneau présentant au moins une première arête rectiligne de hauteur donnée, sur laquelle la feuille de recouvrement se trouve également appliquée etcollée, et au moins une seconde arête rectiligne, qui est adjacente à la première mais qui est non recouverte par la feuille de recouvrement. Selon cette méthode,on se procure un bout droit de matériau rigide de longueur au moins égale à celle de la seconde arête, ce bout droit ayant une surface plane de largeur constante et une hauteur identique à celle de la première arête, sur lesquelles une feuille de recouvrement analogue à celle recouvrant le panneau est également appliquée et collée. Ce bout droit peut être un rebut d'un panneau analogue. On coupe alors à l'aide d'un gabarit une encoche dans le panneau sur toute la longueur de la seconde arête, en suivant une première ligne de coupe s'étendant à angle depuis le point de rencontre des première et seconde arètes, puis en suivant une seconde ligne de coupe parallèle à la seconde arête, ladite première ligne de coupe ayant une longueur choisie avec précision de façon à ce que l'encoche ainsi coupée soit de largeur égale à celle du bout droit que l'on s'est procuré. On coupe ensuite à l'aide d'un autre gabarit le bout droit de façon à ce que, d'une part, la longueur de celui-ci, du côté de sa hauteur recouverte, soit précisément égale à celle de laseconde arête et que, d'autre part, ce bout droit ait une extrémité coupée en retrait depuis la hauteur recouverte de celui-ci selon le même angle que la première ligne de coupe. Enfin, on applique et fixe le bout droit coupé dans l'encoche faite dans le panneau de façon à ce que l'extrémité coupée de ce bout droit soit adjacente à la première ligne de coupe de l'encoche et à ce que les surfaces recouvertes du panneau et du bout droit soient coplanaires, ceci donnant à la seconde arête du panneau un aspect identique à celui de la première arête. Cette méthode est notamment utilisable pour la finition de comptoir de cuisine.

Patent CA-2118915-A1 (CA)
Title: Process for reducing frequency interlacing during acoustic or optical signal transmission and/or recording
Inventor: EDLER BERND
IPC: G10L19/032
Filed: 1992-10-06
Abstract: The intention relates to a method for reducing frequency crosstalk in the trans-mission of digitized audio signals. Frequency crosstalk must always be expected if the subdivision of the input signal takes place on partial bands in series-connected stages. In the method according to the invention signals from partial bands in which spectral components of specific frequencies occur as signal components and signals from partial bands in which said spectral components occur as crosstalk components in the stop range undergo a weighted summation. Following transmission, the partial band signals undergo an inverse operation to the weighted summation. The method operates independently of the chosen encoding process and is consequently universally usable.

Title: Method and apparatus for effecting gas-liquid contact
Inventor: SMITH JAMES W
IPC: B01D53/78
Filed: 1993-04-05
Abstract: Components, usually but not exclu-sively gaseous components, are removed in a liquid medium from gas streams and chemi-cally converted into an insoluble phase or physically removed. Specifically, hydrogen sulfide may be removed from gas streams by oxidation in aqueous chelated transition me-tal solution in a modified agitated flotation cell. The same principle may be employed with other procedures in which a gaseous phase is dispersed in a liquid phase to effect an interaction between components present in such phases, for example, to treat or strip or react a component of the liquid phase. A gas-liquid contact apparatus, which may be a combined chemical reactor and solid pro-duct separation device, also is described. In order to effect efficient mass transfer and rapid reaction, gas bubbles containing hy-drogen sulfide and oxygen are formed by ro-tating an impeller at a blade tip velocity of at least about 350 in/sec. to achieve the re-quired shear. To assist in the reaction, a surrounding shroud has a plurality of openings, generally of aspect ratio of approximate-ly 1, of equal diameter and arranged in uniform pattern, such as to provide a gas flow therethrough less than about 0.02 lb/min/ opening in the shroud. In general, the gas velocity index of gas through the openings in the shroud is at least about 18 per second per opening, preferably at least about 24 per second per opening. Each of the openings has an area correspoding to an equivalent diameter less than about one inch.

Abstract: A data communication system is provided for use with a cellular system containing an array of cells and a cellular transmitter/receiver located within each cell of the array. Each cellular transmitter/receiver is adapted for transmitting and receiving voice and/or data communication over predetermined channelized frequencies associated with the particular cell in which the cellular transmitter/receiver is located. In accordance with the invention a base data transmission station is located in each cell and is adapted for transmitting a single data stream across a plurality of channels, each of which channels is adapted to carry a single stream of information. Each base data transmitting station does not transmit on the predetermined channels that are assigned to the particular cell in which the base data transmitting station is located (i.e., those channels are "notched"). In one embodiment used channels that are carrying streams of information in adjacent cells are detected and the base data transmission station does not transmit over the frequencies of the used channels (i.e., the used channels are "notched"). In this manner, the single data stream transmitted by the base data transmitting station is transmitted over all of the channels of the cellular array except for the channels that are notched. The base data transmitting station also transmits a notching pattern, which is continuously updated, to mobile transmitters within the cell. The notching pattern comprises information concerning the channels in the cell that are notched and information concerning used channels of adjacent cells that are notched. The mobile transmitters in the cell will transmit a single data stream over all of the plurality of channels of the cellular array except for the notched channels.
