This invention refers to innovative water sprays applications to significantly improve coal and quartz dust control around a continuous miner. According to the invention, said interface element and said valve are shaped such that said valve can be attached to said cylinder head via at least a first attachment means extending through at least the interface element. The first position may allow fuel vapor to flow between the fuel tank and the air intake passage and the second position may inhibit the fuel vapor from flowing between the fuel tank and the air intake passage. The tabs, which are inwardly bent, are held against the closed, rear end of the receiver extension by the action spring, whether the spring is fully compressed or only partially compressed. The detection and storage in the image memory of feature signals and the readout of the image signal and associated feature signal from the image memory are performed in parallel. A slot in the tab accommodates receipt of a double knot at one end of the ribbon, while a slot in the spool accommodates receipt of a double knot of the ribbon at the opposite end.
