Apparatus and method for the electro-acoustical measurement of the angle ection of passing projectiles at air-tow-targets, wherein at least three acoustical sensors are equidistantly positioned on a fixed sensor ring which is supported by the tow-target, wherein the arrival times of the waves of the projectiles are electronically measured by means of the several sensors.

Apparatus and method for the electro acoustical measurement of the

An apparatus for mixing a first liquid component with at least one additional liquid component. A fluid flow-through measuring device in the form of a gear pulser is connected to a supply line for a first component and generates a number of electrical pulses corresponding to the flow volume. A geared feed pump connected to the supply line for each additional component is driven by an electric stepping motor. A current supply circuit for each stepping motor operates to maintain an adjusted mixing ratio in response to pulses generated by said flowthrough measuring device.
