Abstract: La tension de décharge des étincelles suit un profil descendant (11) pendant au moins une période prédéterminée (B) d'au moins 0,1 ms pendant la combustion normale du mélange air/carburant dans la chambre de combustion d'un moteur à combustion interne. Si la combustion ne se produit pas, la tension s'exerçant sur la bobine d'allumage tombe à zéro le long d'un profil (12) partant d'un point (A') et on peut surveiller l'absence de toute tension de décharge ultérieure à la fin de la période prédéterminée (B), ce qui indique que le carburant non brûlé s'achemine vers le système d'échappement où il peut brûler et provoquer un surchauffage du système d'échappement. Un tel système d'échappement peut contenir un catalyseur, qui risque d'être détruit par un tel surchauffage, ce qu'on évite en utilisant le résultat de l'observation de la tension de décharge pour interrompre l'arrivée de carburant dans le moteur, au moins jusqu'à la prochaine opération d'allumage.

Abstract: A process for co-production of a pitch for the manufacture of HP carbon fibers and a pitch for the manufacture of GP carbon fibers is proposed. The pitch for the manufacture of GP carbon fibers is prepared from the spent fraction not used in the production of an optically anisotropic pitch suitable for the manufacture of HP carbon fibers. The spent fraction has hitherto been discarded as a valueless material. According to the present process, a pitch for the manufacture of so-called ultra HP carbon fibrs with tensile strength of over 400 Kg/mm² and modulus of elasticity of over 60 ton/mm′ and a pitch for the manufacture of GP carbon fibers can be produced simulteneously. Both pitches have very excellent spinnability and when they are spun, they cause no fiber cut-off even at a high spinning rate of, for example, 500 m/min or 700 m/min. One important merit of the process is that the production ratio of ultra HP carbon fibers and GP carbon fibers can easily be changed to accommodate to market's demand. Accordingly, the process has wide flexibility in operation. Of course, the effective utilization of valueless spent fraction can reduce the production costs of not only ultra HP carbon fibers but also GP carbon fibers.

Abstract: Toughened polyamide compositions are produced by melt blending a polyamide component and a partially crosslinked elastomeric modifier component containing reactive functionalities. Generally a multiple phase composition is formed wherein the polyamide constitutes a continuous phase and the elastomeric modifier component constitutes a discontinuous phase having a particle size of at least 1.3 or 1.5 microns and preferably at least 5.0 microns. The discontinuous elastomeric modifier component is made by adding reactive functionalities to an existing elastomer polymer and partially or semi-­crosslinking the same in the presence of free radical initiators such that at least 10 percent gel exists. The amount of the elastomeric modifier component is generally from about 1 to about 85 percent by weight. The poly­amide compositions have a wide range of improved proper­ties such as good low temperature (e.g., minus 40°C) impact resistance and good high temperature heat deflec­tion (e.g., 65°C).
