    • A device for a moving body, to measure the speed of the moving body over a surface having local irregular features, having sources to illuminate local areas of the surface under a leading and a trailing photo-electric converter on the moving body which produce two sequences of electrical signals which correspond to the irregular feature of the surface at two points running in common with the body, that are spaced one from the other in the direction of movement. A delay unit with an adjustable delay for the signal output of the leading converter, a multiplication circuit for multiplying the delayed signals of the leading converter by the undelayed signals of the trailing converter, a low pass filter connected to the output of the multiplication circuit, a control circuit for adjusting the delay of the delay unit to a value which corresponds to a timely coincidence of the two consecutive signals obtained from the same point at the two inputs to the multiplication circuit, and an indicating device which on the basis of the delay time and the spacing of the two points indicates at any time the relative velocity of the moving body, so characterized that a filter is interposed in the connection between each photo-electric converter and the multiplication circuit, the frequency characteristics of which are different and so chosen that the valves obtained at the output of the low pass filter go through zero, when the delay time of the delay unit is equal to the time required to cover the said distance at the instant of the measurement.

    • A circuit for monitoring the readiness for functioning of at least one DC operated signal lamp, the circuit comprising a pulse generator for supplying test pulses through a logic system to a switching transistor; the signal lamp being operated by the switching transistor when a signal voltage is applied to the transistor through the logic system. An indicating circuit is connected to the pulse generator and the transistor to provide a fault indication if a voltage, which does not correspond to the switching state of the transistor determined by the test pulse, occurs on the connection between the lamp and the transistor during each test pulse.
