A surface layer for forming a cylinder barrel wall of a combustion engine block is proposed. The data-gathering client computers poll a central server for a target site to access. The writing apparatus further has a remote tracking arm with two photodiodes suitably mounted thereon to receive the reflected beams. Downstream from the two choke means each control chamber is connected with a venting connection. By means of the method in this invention, SYSLOG messages can be rapidly parsed from the received transport payload by the receiver of the SYSLOG messages. An airtight room is defined between the chipping collecting container and the collecting bag.
