Title: Appareil et methode d'affichage de signaux video numeriques comprimes enregistres a haute definition
Inventor: KNAUER SCOTT C
IPC: H04N19/50
Filed: 1993-01-04
Abstract: L'invention est un appareil qui produit sous la forme de données numériques une représentation d'un signal d'imagerie vidéo à haute définition comprimé, de telle façon qu'un magnétoscope courant utilisant les technologies électriques et mécaniques actuelles peut être adapté pour lire ces données afin de les afficher dans des modes spéciaux tels que l'avance rapide, l'affichage en sens inverse et l'arrêt sur l'image. Pour minimiser les pertes de données quand le magnétoscope utilise l'un de ces modes spéciaux, la représentation du signal d'imagerie à haute définition est décodée par l'appareil de l'invention pour produire les créneaux temporels disponibles dans la chaîne de données. Ces créneaux sont alors remplis avec des données qui sont une duplication des données les plus importantes parmi les données transmises originellement qui occupent alors les autres créneaux temporels de la chaîne de données. Cette duplication des données accroît la probabilité de lecture des données d'imagerie importantes par le magnétoscope quand celui-ci utilise un mode spécial. Pour accélérer le retour à la normale après la perte de synchronisation, l'appareil utilise un fragment de l'image originelle qui est incorporé dans chaque section ou tranche de l'image transmise. Quand la synchronisation est rétablie, l'image vidéo à haute définition est construite à partir de l'image contenue dans les tranches.

Title: Cartridge of hollow fiber membrane wafers and module containing stacked cartridges
Inventor: PEDERSEN STEVEN K
IPC: B01D63/04
Filed: 1993-03-02
Abstract: CARTRIDGE OF HOLLOW FIBER MEMBRANE WAFERS AND MODULE CONTAINING STACKED CARTRIDGES                 ABSTRACT OF THE DISCLOSURE A tubular module is disclosed for use as a membrane device, comprising, a shell with fluid couplings removably affixed to each of its ends and at least one non-disassemb-lable cartridge operably held within the shell. The cart-ridge is constructed from plural wafers sequentially co-axially aligned, each wafer consisting essentially of a generally planar frame and an array of hollow fibers of selectively permeable material adhesively held by their ends in opposed portions of the border of the frame, with-out potting the ends. Several cartridges may be coaxially "ganged" to provide a "stack" with the required filtration area. The cartridges may be removably disposed in the shell, or secured therein so that the entire module may be discarded when its efficiency is unacceptably low. The wafers are adhesively secured to define a fluid-tight conduit with open ends through which a feedstream is flowed transversely over the fibers. The bores of the fibers are in open fluid communication with the permeate zone in the shell. A frame of a wafer may be provided with longitud-inal, laterally spaced apart grooves in its upper surface and the fibers trained in the grooves. A cartridge may be made by precoating a first frame with adhesive, embedding the fibers in the adhesive, initially curing the adhesive and then placing a second frame over the partially cured adhesive; and, repeating the steps. Alternatively, the second frame may be positioned over the embedded fibers on the first frame and the adhesive then cured. The arrays lie in a plane substantially orthogonal to the direction of flow of a feedstream to be treated, and fibers of one array are staggered relative to those in a successive array.

Patent CA-2093830-A1 (CA)
Title: Process and device for continuous extraction and analysis of fluid using membrane
Inventor: PAWLISZYN JANUSZ
IPC: B01D61/24
Filed: 1993-04-13
Abstract: A process and a device for the continuous extraction and analysis of chemical substances from solute fluid using membrane is characterized by passing solute fluid 14 through housing 20 on one side of a semipermeable structure 19 and simultaneously passing extracting fluid 11 through the housing on the other side of the semipermeable membrane structure. Substances passing from solute fluid through the semipermeable membrane structure into the extracting fluid are delivered by the extracting fluid as carrier, into a sorbing phase 27. Cooling 28 and heating 24 of the sorbing phase allows substances to be concentrated and detected by detector 50 and to be continuously monitored. Extracting fluid may be a gas or a pressurized dense gas. Extraction using pressurized dense gas and membrane is achieved by maintaining the pressure of the solute fluid and the pressurized dense gas within a high pressure housing substantially equal. Previously, solute fluids were analyzed using batch processes with liquid-liquid extraction, extraction cartridges or purge and trap. Continuous extraction and analysis using membranes eliminates the use of organic solvents and provides inexpensive and continuous monitoring of volatile, semi volatile, non-volatile and polar compounds in water and other fluids.

Patent CA-2108769-A1 (CA)
Inventor: REITINGER GOTTFRIED
IPC: H02K11/04
Filed: 1992-04-23
Abstract: 2108769 9220134 PCTABS00017 The aim of the invention is to obtain a tubular turbine synchronous generator of cost-effective design and improved reliability. A tubular turbine synchronous generator has a stator (1) and a rotor (2) arranged in a tubular turbine housing (3). The tubular turbine housing (3) is sealed on the side facing the oncoming driving water (4) by the dome (5) of the tubular turbine. The generator is cooled by an intermediate circuit (6). This cooling efect is exploited to cool the rectifier elements (7). The rectifier elements are disposed with their respective cooling bodies in the dome (5) of the tubular turbine, around which the driving water (4) flows, i.e., directly on the intermediate circuit (6) of the generator cooling system. The cooling bodies for the rectifier elements (7) are thereby indirectly cooled by the driving water (4). The invention makes it possible for the first time to produce a tubular turbine synchronous generator which has no fans and therefore no rotating parts for the excitation. In the calculation of the profitability, costs for purchase of the fans as well as those for losses and maintenance can be neglected. In addition, there are fewer switch cabinets that require maintenance.
