A method of treatment of migraine, cluster headaches and trigeminal neuralgia, radiation or cytotoxic agent induced nausea and vomiting and/or cardiac arrhythmia in mammals, including humans, which method comprises administering an effective amount of a compound of formula (I) or a pharmaceutically acceptable salt thereof: ##STR1## wherein: R.sub.1 is C.sub.1-6 alkyl; R.sub.2 is amino or C.sub.1-7 acylamino; R.sub.3 is halo; one of R.sub.4 and R.sub.5 is hydrogen, C.sub.1-6 alkyl, phenyl or phenyl C.sub.1-3 alkyl, which phenyl moieties may be substituted by one or more substituents selected from C.sub.1-6 alkyl, C.sub.1-6 alkoxy, CF.sub.3 or halogen; the other of R.sub.4 and R.sub.5 is hydrogen or C.sub.1-6 alkyl; p is 0 to 2; and q is 0 to 3.
Device for locking a suction nozzle of a separating sucker on a suction head of a sheet feeder of a sheet-processing machine, the suction head having at least one governor foot, a drive device for moving the governor foot in accordance with a working cycle of the feeder, and a device for vertically moving the nozzle of the separating sucker, includes a bearing support laterally disposed on the suction nozzle, a movably arranged abutment device for supporting the bearing support, when the suction nozzle is in a lifted position, until a trailing edge of a sheet supplied to the feeder has left the vicinity of the suction nozzle of the separating sucker, and a linkage connecting the abutment device articulatingly to the drive device for the governor foot for moving the abutment in accordance with a working cycle of the suction head.
Benzoic acid derivatives of the formula ##STR1## where X is oxygen, sulfur, --NH, --NR.sup.1, --N--CN, --N--OR.sup.1 or --N--NO.sub.2 ; Y is a single bond, --C.dbd.C--, or --NH; R.sup.1 is alkyl, alkenyl, alkynyl, aryl, cycloalkyl, heterocyclo, or (heterocyclo)alkyl; and R.sup.2 is aryl or heterocyclo. The compounds of formula I are useful in the treatment of arrhythmia.
