A filling device including a web-forming station, a filling station, a sampling station, and a retrieval station. The process has an aggregating step of adding an aggregating agent composed of a compound having a divalent or trivalent metal element into a dispersion with fine particles of a binder resin dispersed in an aqueous medium, and an aggregation terminating step of adding an aggregation terminating agent into the dispersion. In another aspect of the present invention, a network of shared end-user computers periodically backs up each individual end-user computer to a central instrumentality, in a novel manner to reduce storage and time requirements. The prefix value is combined with the master key from the processing unit to create a random value that is the seed for a hashing algorithm. The services platform allocates a unique private IP address space to the enterprise network, and translates IP addresses in network communications between enterprise network addresses and corresponding services platform addresses in the allocated unique private address space. As such, the heat built-up within the computer system can be effectively dissipated so as to prolong the service life of the computer.
