At least two ignition capacitors are provided for igniting an ignition pill of a motor vehicle passenger protection system. The at least two ignition capacitors are at first connected in parallel, at the beginning of an ignition process, and are connected in series only after a given time interval has elapsed from the beginning of the ignition process. This ensures that the ignition current flowing through the ignition pill is always sufficiently strong and at the same time avoids initial energy losses.

Methods and compositions useful for inducing a cyctotoxic t-lymphocyte (ctl)in a human or domesticated or agriculturally important animal. The method includes the steps of providing the antigen to which the ctl response is desired and providing an antigen formulation which comprises, consists, or consists essentially of two or more of a stabilizing detergent, a micelle-forming agent, and an oil. This antigen formulation is preferably lacking in an immunostimulating peptide component, or has sufficiently low levels of such a component that the desired ctl response is not diminished. The formulation is provided as a stable oil-in-water emulsion.

Disclosed are benzopyran dyes of formula (I), wherein n is 1 or 2; X1 is oxygen or imino; X2 is cyano or carbamoyl; R?1 and R2? are C?1?-C13 alkyl, where the sum of the carbon atoms in R?1 and R2? must be at least 10, and R3 is hydrogen, C?1?-C6-alkyl, C1-C6 alkoxy, halogen, cyano, nitro, carbamoyl, C1-C4 mono- or dialkyl carbamoyl, sulfamoyl or C1-C4 mono- or dialkyl sulfamoyl. Disclosed also are iminocoumarins as their intermediates and the use of the new dyes for dyeing or printing synthetic materials.
