    摘要: The present invention provides an apparatus and method for applying road marking material to a pavement surface. The apparatus includes a vehicle having a holographic sight and at least one road marking material applicator mounted thereon. In accordance with the method, an operator of the vehicle steers the vehicle to a desired position on the pavement surface based upon aiming information observable through the holographic sight.

    摘要: A 2-oxo-5-methyl-5,6-dihalopiperidine is contacted in a high boiling solvent, preferably trichlorobenzene, with a stoichiometric excess, up to 70 mole % excess, of a chlorinating agent, preferably phosphorus oxychloride or phosgene, at an elevated temperature between 80.degree. and 130.degree. C. The solution of 2-chloro-5-methylpyridine so obtained may be used directly for further chlorination to form 2-chloro-5-trichloromethylpyridine with, for example, chlorine gas in the presence of a free radical initiator. This chemical intermediate is useful in the synthesis of certain herbicidal compounds.
