Abstract: An autoclave for pressure oxidation of a slurried material including at least one sulfide material, and a method. The autoclave includes a pressure vessel for receiving the slurried material. The pressure vessel includes compartments being arranged horizontally one after the another and separated by dividers. Each divider is provided with an upper edge or at least one opening that defines level of the slurried material in the compartment. An inlet is arranged for feeding oxygen-containing gas into the pressure vessel. An agitator arrangement is arranged for agitating the slurried material in at least one of the compartments, the agitator arrangement including at least an upper impeller and a lower impeller, the impellers arranged along a vertically aligned shaft. The upper impeller is arranged at a height above the mid-level of one of the compartments, and the upper impeller is an upward pumping axial or mixed flow impeller.

Abstract: The invention relates to a network part and a method for generating billing data in a mobile communications system employing a wireless application protocol. The network part of the mobile communications system comprises: means for setting up a bi-directional wireless data transmission connection to a subscriber terminal; means for transmitting a service request sent by the subscriber terminal to a contents server providing the service; means for transmitting response data generated in the contents server on the basis of the service request to the subscriber terminal; identifying means for identifying transactions associated with the service from among the service requests and the response data on the basis of the identification of the Internet address of the service referred to in the service request and the response data; and billing means for generating billing data for the service using the transactions identified on the basis of the service's Internet address.
