Title: Procede et appareil de traitement de l'air pollue par des solvants organiques volatiles
Inventor: BIBEAU LOUISE
IPC: B01D53/72
Filed: 1997-07-18
Abstract: Cette invention est reliée à un procédé de traitement par biofiltration d'un flu ide gazeux comprenant des polluants organiques volatiles, tels que solvants organiques volatiles (SOV). Le biofiltre est composé d'un consortium de microorganismes sélectionnés pour leur grande capacité de dégrader les BTEX (benzène, toluène, éthylbenzène, xylènes) et les alcools. Avantageusement, ces microorganismes sont inoculés sur un lit filtrant vertical composé de (i) tourbe granulée; (ii) d'un matériau non-compactable et liant comme le PVA, la gomme de guar, l'acide polyacrylique, le polyacrylamide, un silicate ou du ciment; (iii) un agent tampon pour permettre d'adhésion des microorganismes sur le mélange tourbe/liant; (iv) un matériau retenant l'humidité; et (v) un matériau de finiti on adsorbant les polluants dégradés ayant échappé à une conversion en produits non-polluants, avant la relâche du fluide gazeux dans l'environnement. Le fluide gazeux chargé en polluants est introduit au bas du biofiltre et remonte en traversant le lit filtrant qui en capture les polluants et les convertit en diox ide de carbone et en eau. Le procédé, le biofiltre et le système de traitement permette nt une capacité d'élimination d'environ 165 g/m3.h de toluène pour une charge de 200 g/m3.h. Le système est peu dispendieux, compact, efficace, et facile à opére r.

Patent CA-2218160-A1 (CA)
Inventor: MAO WEIDONG
IPC: H04N21/236
Filed: 1997-10-10
Abstract: A secondary packetized data stream (IS), such as a commercial, is spliced with a primary packetized data stream (MS), such as a network television program. The system does not require decompression of the data in the primary data stream, and is particularly suitable for use at a cable system headend to allow the insertion of commercials from local businesses into a nationally broadcast television program. When a start signal (T_in)is received, a pre-splicing packet (700, 800, 900, 1000) of the primary stream is determined. The pre-splicing packet is the packet closest to the start time which carries an anchor frame (e.g., I or P frame) start code (706, 804, 905, 1003). To prevent a potential discontinuity at the decoder (168), the pre-splicing packet (700, 800, 900, 1000) is processed to discard the anchor frame data, and to insert a number of stuffing bytes (712, 812, 912, 1012) which is equal to the number of bytes discarded into an adaptation field of the pre-splicing packet. To further maintain continuity at the decoder, identifying data of the primary stream such as PID and PSI data, is retrieved and provided to the secondary stream. A number of null packets (430) are inserted into the output stream (OS) at the transition point between the main program and the commercial to prevent a buffer overflow at a decoder (168) which receives the output stream (OS).
