Abstract: An electric plug-in device, which is suitable for plugging into an electric receiving device, has an inner conductor and an insulating body that encloses the inner conductor. The plug-in device includes a retaining element which can be firmly connected indirectly, in particular with the help of a housing wall, or directly to the receiving device; a sliding element which can be moved axially along a longitudinal axis of the inner conductor relative to the retaining element includes the internal conductor and the insulating body. When the plug-in device is plugged into the receiving device, the sliding element protrudes into a receiving portion of the receiving device. A spring device exerts an axially active spring force on the sliding element in the direction of the receiving device when the plug-in device is plugged into the receiving device.

Abstract: A high-voltage feed-through contains a securing flange for securing the high-voltage feed-through to a wall. The securing flange contains a retaining part and a moving part, wherein the moving part is mounted relative to the retaining part such that it can rotate in relation to a longitudinal direction of the high-voltage feed-through. An electrical device contains a fluid-tight housing and the high-voltage feed-through. A device connection part is provided for receiving and contacting the high-voltage feed-through.

Abstract: The compounds of formula I are described ##STR1## wherein Hal is halogen, such as fluorine, chlorine, bromine or iodine;R.sub.1 is hydrogen, C.sub.1 -C.sub.6 alkyl or C.sub.3 -C.sub.7 cycloalkyl;R.sub.2 is hydrogen, C.sub.1 -C.sub.6 alkyl or C.sub.3 -C.sub.7 cycloalkyl, andR.sub.3 is hydrogen or C.sub.1 -C.sub.6 alkyl,for use in a method of controlling fleas in domestic animals, especially in dogs and cats, wherein systemic administration is preferred. The compounds of formula I are administered in an amount effective against fleas via the digestive tract or via the blood of the host animal and thus systemically to the domestic animal, especially the dog or the cat.

Abstract: The invention relates to the use of N-3-(5-trifluoromethylpyridyl-2-oxy)phenyl-N'-benzoylureas of formula I ##STR1## wherein R.sub.1 is hydrogen, C.sub.1 -C.sub.2 alkoxy, C.sub.1 -C.sub.2 alkylthio, C.sub.1 -C.sub.2 alkyl or halogen,R.sub.2, R.sub.3 and R.sub.5 are independently of each other hydrogen or halogen, andR.sub.4 is hydrogen, C.sub.1 -C.sub.2 alkyl or halogen,for controlling helminths, especially nematodes and trematodes, in domestic animals and productive livestock.
