Abstract: In a control equipment for an industrial sewing machine, it being possible, via switchgears such as switches, probes, sensors or the like, to switch on or off functions and connection states, by a certain voltage level being applied to an input circuit of the control, the input circuit generating an output signal, it is provided that upon the application of varying input voltages Ue, the output voltages Ua generated are the same in each case.

Abstract: The invention relates to a film-type ignition element, used in particular for igniting the propellant charge of large-caliber ammunition. The invention furthermore relates to a method for producing an ignition element of this type.

Abstract: The invention relates to a method of making pourable, plastic-bound explosive charges or rocket propellants, to which a metal powder having essentially spherically shaped grains is added.

Abstract: An igniting system for a projectile propellant includes a combustible support tube having an outer surface and an inner surface; a plurality of throughgoing apertures provided in the support tube; a free igniting channel coaxially surrounded by the support tube; and an ignition transfer charge formed of a pyrotechnical hard foam layer having a thickness between 1 and 3 mm and being carried on the outer surface of the support tube. The hard foam layer is composed of a large-pore inner layer and two opposite surface layers which are of densely closed structure and between which the inner layer is sandwiched.
