    摘要： The invention relates to a novel process for preparing chloromethylpyridines of the general formula (I) ##STR1## in which n represents the numbers 0,1,2 or 3 andX represents halogen,by reacting aminomethylpyridines of the general formula (II) ##STR2## with a nitrosating or diazotizing agent in the presence of a diluent and optionally in the presence of hydrogen chloride at temperatures between -20.degree. C. and +50.degree. C. and then working up in a conventional manner.

    摘要： The title compounds of the formula ##STR1## can be prepared by cyclization of aminomethylenated 2-pentenoic acid derivatives of the formula ##STR2## where R, X, R.sup.1, R.sup.2 and Z have the meaning given in the description,in the presence of acids or ammonia. Preferably, aminomethylenated pentenoic acid derivatives are employed which can be prepared from pentenoic acid derivatives of the formulaR--CH.sub.2 --CH.sub.2 --CH.dbd.CH--Z (III)orR--CH.sub.2 --CH.dbd.CH--CH.sub.2 --Z (IV)with ortho-amides of the formula ##STR3## The meanings of A and B are also given in the description.

    摘要： A recording device is for recording the switch state of an electromagnetic switch device. In at least one embodiment, the recording device includes a housing, in which a plunger is movably mounted. The plunger may be moved between two mechanical end positions, wherein the end positions of the plunger correspond to the switch states of the electromagnetic switch device. A sensor device is arranged in the housing by which it may be recorded in which of the end positions the plunger is and from which a corresponding electrical signal may be emitted. The sensor device is designed to be able to record the position of the plunger without contacting the plunger.
