    摘要: A process for phosphating metal surfaces by treatment with an acidic zinc- and phosphathe-containing solution which does not require rinsing. The metal substrate is contacted with a phosphating solution containing 2 to 25 g/l of zinc ions, 2 to 25 g/l of manganese ions and 50 to 300 g/l of phosphate ions. The solution has a pH value of 1 to 3.6, a free acid content of 0 to 100 points, a total acid content of 40 to 400 points and a ratio of free acid to total acid of 1:4 to 1:20.

    摘要: In a method for measuring the transmit time of light, in particular for cameras, a first light signal which is clocked by a first clock controller (16) is input into a light system (14) by a light transmitter (12) and is reflected back to a receiver photodiode (13) by means of a reflective objective (O). The photodiode (13) determines a reception signal as a result of the first light signal. By virtue of the fact that a further light signal which is clocked by a further clock controller (17) is input into the photodiode (13) at an angle with respect to the first light signal and is mixed at the photodiode (13) with the first light signal to form a common reception signal (S13), that the common reception signal (S13) is filtered with a filter (25) whose frequency response corresponds to the frequency of the clock difference in order to form a filter signal, in that the clock signal of the first clock controller (16) and of the further clock controller (17) are also mixed in a mixer (30) in order to form a mixed signal and in that the phase shift between the mixed signal of the clock controllers (16, 17) and the filter signal is used to determine the transit time of light, a method for measuring the transit time of light is provided which can operate in particular with cameras even with relatively inexpensive components and relatively low-frequency amplifiers.
