Title: Apparatus and method for formatting access channel of mobile terminal
Inventor: OK YUN CHEOL
IPC: H04B7/26
Filed: 2002-11-12
Abstract: PURPOSE: An access channel format apparatus and method of a mobile communication terminal are provided to enhance a call connection rate by changing a format of an access channel suitably according to a capsule size of the access channel supported in a low-version base station. CONSTITUTION: A controller receives a wireless network(P_REV) through an RF processor(S12) and discriminates whether the wireless network(P_REV) is greater than '6'(S14). If the wireless network(P_REV) is equal to or greater than '6', the controller determines that a wireless network protocol corresponds to IS-95C or greater and selects a smaller one of the received P_REV and a terminal P_REV(Mob_P_REV) stored in a memory(S16) as a P_REV determining the size of an access channel. If the wireless network(P_REV) is smaller than '6', the controller selects a smaller one of a value(P_REV-2) obtained by subtracting 2 from the received wireless network(P_REV) and the terminal P_REV(Mob_P_REV) as a P_REV determining the size of the access channel(S18). The controller determines a MAX_CAP_SZ according to the selected minimum P_REV(IN_USE P_REV) and constitutes an access channel message(S20). The controller transmits an access probe including the access channel message to a base station(S22).

Title: Method for drying paste-like materials
IPC: C02F11/12
Filed: 2001-07-30
Abstract: On drying pasty materials, particularly sewage sludge, the material is compacted in an intermediate drying stage with a dry fraction of 60 to 80%, so that relatively low energy costs are required. The conveying of the material takes place both during pre-drying and after leaving the compactor on one or two air-permeable conveyor belts (3, 4) succeeding one another in the conveying direction and which are enclosed in a common housing (2). Thus, drying before and after compacting is performed under identical method conditions, so that it is possible to produce a simple and therefore inexpensive installation for performing the method. The finished product has advantageous characteristics with regards to density and abrasion resistance, so that dust production is avoided during subsequent handling.
