Abstract: The present invention relates to a device for the lashing of containers, which is to be attached between two fastening points, which are secured to one another, with a first clamping device, which can be connected to one of the fastening points and contains a spindle, which extends in the longitudinal direction of the first clamping device and has a spindle/threaded section, a second clamping device, which can be connected to the other of the fastening points, a spindle nut, which has a spindle nut/threaded section, which engages with the spindle/threaded section of the first clamping device, a locking means allocated to the spindle nut. The locking means enables reciprocal rotation of the two clamping devices in at least one direction of rotation corresponding to the tightening of the device, and that it counters the rotation in the opposite direction, and the locking means has at least one pre-tensioning element.

Abstract: A clock filter circuit (20), which serves for filtering the clock of non-isochronous data signals having a selected one of at least two nominal data rates, has an auxiliary clock source (21) that generates an auxiliary clock signal (27) with a pulse repetition rate which is in the range between the at least two predetermined data rates, a delay line (22) connected to the auxiliary clock source (21) for creating a set of mutually delayed copies of the auxiliary clock signal and a multiplexer (23) that switches in a cyclic order between the delayed copies according to predetermined rules, which depend on the selected data rate to generate a filtered clock signal (28). A control circuit determines whether the rate of the filtered clock (28) signal must be increased or decreased as compared to said data signal and controls the multiplexer (23) to delay or advance the cyclical switching accordingly.
