Abstract: A propellant charge, a priming cap including the propellant charge and a weapons training system including the priming cap are characterized in that the propellant charge contains a soft friction agent. The propellant charge can contain at least one impact-sensitive explosive substance as a heavy-metal-free priming compound, and the soft friction agent can be marble, calcite, dolomite, soft carbonates and/or mixtures thereof.

Abstract: An apparatus for determining a thickness of a layer of fat of an organism, the apparatus comprising a plurality of electromagnetic radiation sources adapted for illuminating the layer of fat with a plurality of pulses of electromagnetic radiation, at least one electromagnetic radiation detector adapted for detecting detection signals indicative of the pulses of electromagnetic radiation after transmission through the layer of fat, and a determining unit adapted for determining a plurality of values of the thickness of the layer of fat based on an analysis of a plurality of ratios between the detection signals, wherein only those values are used for calculating an average thickness of the layer of fat which values result in deviations from the average thickness of less than a predetermined threshold value.

Abstract: The metering apparatus for small volumes of liquid in the milliliter and microliter range comprises a piston/cylinder system driven by a direct-current motor. The piston stroke is measured by means of an optical path-length measuring system. For this purpose, a slide-rule pulse scale provided with a regular line grid is affixed to the piston. The light from a light transmitter passes through the slide-rule pulse scale and a stationary scanning plate which likewise is provided with a regular line grid, and to a light receiver. The pulses of the light receiver are digitalized in a pulse conditioning circuit and fed to a counter adapted to be preset by means of a coding switch. The counter position acts upon a braking and rotative-speed regulating circuit in such a way that regardless of the preset desired value of the rotative speed the speed of rotation of the motor is reduced to a small value as the final value is approached.
