Abstract:
Methods and systems are described for communication of data over a communications bus at high speed and high pin efficiency, with good resilience to common mode and other noise. Pin efficiencies of 100% may be achieved even for bus widths of four or fewer wires. Information to be transmitted is encoded as words of a vector signaling code, each word comprising multiple values transmitted as a group over the communications bus. Subsets of the vector signaling code have distinct group characteristics, which are discernable on transmission and are used to facilitate decoding on reception.

Abstract:
A dual fluid spray nozzle (20) adapted to produce a finely atomized spray of a liquid includes a body (30) which encloses a first atomization chamber (36, 36'), a nozzle tip (70, 70'), and a plate (60, 60', 60'') disposed between the first atomization chamber and the nozzle tip so as to define a second atomization chamber (55, 55'). The plate defines a plurality of passages (61, 61', 61'') through which liquid passes from the first atomization chamber into the second atomization chamber and is further atomized. The nozzle may include a plurality of plates (60', 60''; 80', 80'') and more than two atomization chambers (36', 36'', 55'). In such embodiments, each plate has a reduced total cross-sectional area of passages relative to the preceding plate.
Abstract:
An improvement to methods for heat treating flue gas cleaning residues (1) and residues from the industrial process generating said flue gases. For this purpose, the method comprises a physicochemical treatment step (2, 7), a heat treatment step (13) and a step involving treating gases generated by said heat treatment (19, 22, 28). These three steps are closely overlapped and combined both to minimise the volatilisation of volatile compounds during heat treatment and to remove separately the elements that cannot effectively be immobilised in the treated residue matrix during said heat treatment. The physicochemical treatment step may advantageously be combined with the wet cleaning step that may be included in the industrial process flue gas cleaning step. The method is particularly suitable for melting/vitrifying fly ash, agglomerating the finest fly ash, and destroying organic compounds such as dioxins and furans.
Abstract:
A method of wet cleaning of gases containing condensable organic pollutants in which the organic pollutants are immobilized in the scrubbing liquid by an intermediate phase in this liquid, then destroyed generally by oxydation within said liquid. Application in the collection and destruction of dioxines and furans found in particular in incineration gases.
Abstract:
Improved methods for wet cleaning gases to remove barely soluble gaseous pollutants such as mercury metal or nitrogen monoxide. A potent oxidising agent is used to oxidise the pollutants on the surface of the droplets dispersed throughout the gases to be cleaned. The resulting oxidised pollutants have increased solubility and may be transferred into a scrubbing liquid.
Abstract:
Vector signaling codes providing guaranteed numbers of transitions per unit transmission interval are described, along with methods and systems for their generation and use. The described architecture may include multiple communications sub-systems, each having its own communications wire group or sub-channel, clock-embedded signaling code, pre- and post-processing stages to guarantee the desired code transition density, and global encoding and decoding stages to first distribute data elements among the sub-systems, and then to reconstitute the received data from its received sub-system elements.
Abstract:
Selon ce procédé, on sépare (en 2) au moins une partie des poussières initialement présentes dans ces fumées, on dirige (par 102) les fumées ainsi dépoussiérées vers un laveur acide (5), dans lequel on les met en contact avec un liquide de lavage acide (114), et on soumet les poussières séparées à une lixiviation forcée (en 6), au moyen de ce liquide de lavage acide. Avant de les admettre dans le laveur acide (5), on trempe (en 1) les fumées dépoussiérées, entre 50 et 80°C, au moyen d'une suspension (105) d'un produit pulvérulent, apte à adsorber le mercure, possédant une concentration comprise en 0,5 et 5 g/l, de manière à éliminer entre 50 et 100%, de préférence entre 65 et 99%, du mercure initialement présent dans les fumées dépoussiérées.
Abstract:
The invention aims at improving the treatment of solid waste materials by saline blowoff generated by wet gas cleaning methods. For this purpose the method comprises a step of neutralizing the blowoff, a step of concentrating the blowoff and a step of incorporating this concentrated blowoff in the solid waste materials to be stabilised and in additives and hydraulic binders so as to obtain a conglomerate producing a stabilised solid waste material that can be directly disposed of. These three steps are closely imbricated and can be combined together. The invention uses two waste materials to be treated, one solid, the other liquid (the blowoff) to make one stabilised waste material. The method is useful for treating fly ash from household refuse incineration plants equipped with a wet flue gas cleaning system by the liquid blowoff thereof
Abstract:
Systems and methods for operating gas cleaning devices (20) utilize vibration generators (22, 24, 26) wherein the systems include sensors (30, 32, 34) and programs for monitoring and predicting resonant conditions of different surface zones (A, B, C) in order to vary the frequency and amplitude of vibrations to establish optimum resonant conditions on such surface zones (A, B, C) and thereby optimize cleaning and operation of such gas cleaning devices (20).
