A method for a user equipment to perform random access to a base station in a wireless communication system that supports multiple uplink and downlink carriers is provided. The banded discharge may include two or more support members and each pair of adjacent support members may be spaced apart a distance W. The sacrificial material 26 is typically a low melting temperature wax and so is removed when the seal arrangement reaches its operating temperature. The processor comprises instructions for accessing the status file over the second network, acquiring the status data from the status file, and processing the status data. Additional embodiments are disclosed. The base of the dosing chamber is disposed with respect to the particulate product feed conduit such that particulate material will not spill over the base into the delivery conduit.
