Abstract: L'invention concerne un emballage destiné à recevoir un support d'informations en forme de disque, notamment un disque compact, comportant un support de disque (1) plat d'une épaisseur de 2 à 4 mm, un revêtement (2) habillant ce support, ainsi qu'un élément de fermeture (3). Le revêtement (2) est de préférence constitué de papier ou de carton et le support de disque (1) ainsi que l'élément de fermeture (3) sont réalisés d'une seule pièce par injection en plastique généralement transparent ou teinté, c'est-à-dire que jusqu'à la première ouverture de l'emballage, ils constituent une seule et même pièce injectée en plastique. Pour prendre en compte l'importance croissante de la nécessité d'un emballage plat et léger mais néanmoins indéformable et peu onéreux, l'élément de fermeture (3) est solidarisé avec le bord libre du revêtement (2). Ainsi, outre une fabrication simple et économique, une protection contre les influences extérieures, inhérente à la fabrication, est également garantie.

Abstract: The present invention provides a method of denitrating exhaust gas, which can control the NOx removal efficiency of exhaust gas at 90 % or higher while suppressing the release of unreacted ammonia to 0.1 ppm or less. The method carries out denitration of exhaust gas for removing nitrogen oxides with catalytic reduction by introducing a nitrogen-oxide-containing gas into a catalyst-filled reaction chamber and adding ammonia as reducing agent in an excessive amount to the same chamber. The method comprises the steps of: introducing exhaust gas and ammonia into a first denitrating catalyst layer disposed on the most upstream side in the gas stream to remove nitrogen oxides; supplying the gas into a first ammonia decomposing catalyst layer disposed on the downstream side of the first denitrating catalyst layer to control the ammonia content to be suitable for the subsequent denitrating process, the first ammonia decomposing catalyst layer having ability to oxidatively decompose unreacted ammonia into nitrogen and nitrogen oxides; then supplying the gas into a second denitrating catalyst layer disposed on the downstream side of the first ammonia decomposing catalyst layer; thereafter supplying the gas into a second ammonia decomposing catalyst layer disposed on the most downstream side to remove the residual ammonia, the second ammonia decomposing catalyst layer being provided with a catalyst which can oxidatively decompose the residual ammonia into nitrogen and nitrogen oxides or a catalyst which can oxidatively decompose the residual ammonia into nitrogen oxides.

Abstract: Each base station in a cellular telephone system includes a signal strength measurement device operable to tune to and make signal strength measurements on not only the frequencies allocated to other cells, but also on its own allocated frequencies. Measurements are made by the device on those of its own frequencies having idle traffic channels to obtain an indication of injected uplink interference. An interference penalty is then assessed against the measured uplink interference for those frequencies having more than a threshold number of idle traffic channels. The adjusted measurements for the frequencies allocated to the cell are then sorted in relative order of idle traffic channel (adjusted) measured uplink interference from a least (adjusted) interfered frequency to a most (adjusted) interfered frequency. An idle traffic channel is then selected for assignment at either call set-up or hand-off from the least (adjusted) interfered frequency.

Abstract: Disclosed are a method and apparatus for making substantially spherical, homogenous petroleum resid pellets having a size range between 0.1 and 10 mm, a penetration of essentially 0, a softening point temperature from about 200° to about 400°F, a residual water content of from 0.1 to 10 weight percent, and a sulfur content less than 10 weight percent. The process includes feeding the material in a molten state to a rotating prilling head to discharge the material into free space at an upper end of a pelletizing vessel having a diameter larger than a throw-away diameter of the discharged material, allowing the discharged material to break apart, form into substantially spherical liquid pellets, and fall downwardly into a liquid spray and/or bath to solidify the pellets. The apparatus has an upright pelletizing vessel with an upper prilling zone, a sphere-forming zone below the prilling zone, a cooling zone below the sphere-forming zone, a bath below the cooling zone, and a prilling head in the prilling zone rotatable along a vertical axis and having a plurality of discharge orifices for throwing molten material radially outwardly. A vertical height of the sphere-forming zone is sufficient to allow material discharged from the prilling head to form substantially spherical liquid pellets. Nozzles are provided for spraying water inwardly into the cooling zone to cool and at least partially solidify the liquid pellets to be collected in the bath. Also disclosed is pretreatment of a soft resid (softening point temperature below 200°F) by air oxidation to produce a hard resid suitable for feed to the prilling head.
