Abstract: L'invention concerne un procédé de production de soufre élémentaire à partir de sulfure d'hydrogène contenu dans un débit d'entrée de gaz acide, dans lequel on fait réagir le sulfure d'hydrogène et le dioxyde de soufre dans une unité de récupération de soufre uniquement catalytique, comprenant un convertisseur catalytique unique contenant une zone de réaction catalytique Claus. On recycle un gaz enrichi en dioxyde de soufre, récupéré à partir du traitement des gaz résiduaires et on l'introduit dans la zone de réaction catalytique intégré à un mélange gazeux d'alimentation contenant également le débit d'entrée de gaz acide. Les températures à l'intérieur de la zone de réaction catalytique sont modérées efficacement par recyclage des effluents de gaz résiduaires vers le convertisseur, de telle manière que de fortes concentrations en sulfure d'hydrogène dans ledit débit de gaz acide peuvent être tolérées, ce qui assure une flexibilité et une capacité améliorées du processus. L'invention concerne également un procédé de pré-traitement consistant à mettre en contact le gaz acide avec un lavage aqueux acide, et ce afin de réduire la concentration d'hydrocarbures insaturés dans le gaz acide et d'inhiber la désactivation du catalyseur d'oxydation.

Abstract: A harvester with a control system responsive to at least one crop processing variable for automatically controlling forward speed of the harvester includes a crop presence responsive switch connected to an automatic harvester control system. The switch, preferably a proximity switch responsive to movement of the feeder house drum from an empty feeder house limit position, provides a signal in response to crop entering the feeder house for initiating the automatic speed control of the harvester after the header receives the crop and prior to the crop entering the processing structure. The automatic control initiation structure is particularly useful with an automatic combine throughput control and eliminates unstable operation resulting from delayed control initiation. The switch is part of an adjustable down stop mechanism for the feeder house drum.

Abstract: Site-won spoil from an excavation which is a predominantly non-granular cohesive material can be converted into a material suitable for immediate use as a backfill material by a process of mechanically mixing the spoil with between 0 and 30% by weight or volume of added granular material and between 1 and 10% by weight or volume of a powder material comprising 1-5% lime or with the addition of 1-5% cement and/or 1-5% pulverized fly ash. The process works well with clay soils and the range of suitable spoil can be extended by adding cement to the powder material. The proportions in the mixture are chosen in dependence on the clay and moisture content of the spoil. A machine which can be set to mix the ingredients and water in the correct proportions on site is also described.

Title: Anti-tip arrangement for a mobile storage system
Inventor: KEATON WILLIAM R
IPC: B65G1/00
Filed: 2003-02-05
Granted: 2008-03-18
Abstract: An anti-tip arrangement for a mobile system, such as a mobile storage system, in which a movable member is mounted to a rail arrangement. The anti-tip arrangement includes an anti-tip member which is pivotably mounted to the movable member for movement between an operative position and an inoperative position. The anti-tip member has a hook section that is engageable with art engagement surface of the rail arrangement, for preventing tipping of the movable member relative to the rail arrangement. The anti-tip member further includes a retainer section and a tab section that extend in opposite directions from the pivot axis about which the anti-tip member is pivotable. The tab section extends laterally front the pivot axis, and is engageable by a user to enable the user to pivot the anti-tip member to the operative position. The retainer section is offset from the tab section, and is adapted to receive a releasable retainer member, such as a retainer pin, which maintains the anti-tip member in the operative position. The offset of the tab section from the retainer section facilitates the ability of the user to manipulate the anti-tip member for movement to the operative position while engaging the retainer pin with the retainer section.
