IPC: H04L12/28
Filed: 2008-05-23
Abstract: Middleware is provided as a control plane for WiMAX control messaging. Each ASN in a WiMAX system is associated with a Session Initiation Protocol (SIP) server. A plurality of Functional Entities (FEs) are distributed across the ASNs, wherein each FE (or a group of FEs) associated with a SIP agent. Each FE is operable to control a function associated with a subscriber station (SS). The function controlled by a first FE is transferred to a second FE by employing the SIP agents to establish a SIP session between the first and second FEs. WiMAX control messages are then exchanged over the established session to transfer the SS function from the first FE to the second FE. The first and second FEs may be in the same ASN - the SS mobility is intra-domain - the first and second FEs may be in different ASNs - the SS mobility is inter-domain.

Title: Method and device for the treatment of product gas produced by pressure gasification of solid fuels
Inventor: SCHMITT GERHARD
IPC: F02C3/00
Filed: 2008-05-23
Abstract: The invention relates to a method for the treatment of raw product gas produced by pressure gasification of solid fuels. After cooling to 15 to 45 °C, the following substances are removed by physisorption with cold oxygenate: in a preliminary stage, HCN and NH3; in a first stage, H2S and COS and, if necessary, other sulfurous compounds; and in a second stage CO2. The pure product gas is then conveyed as a reduction gas and/or as a combustion gas to the direct reduction of iron ore. An improvement to the method lies in the fact that the desulfurized product gas is mixed with return gas loaded with CO2 and water vapor diverted from the circulation of the return gas from the direct reduction of iron ore, once the water vapor contained therein has been removed.
