Abstract: The invention relates to a method for preventing and detecting coolant discharges from complex hydraulic systems. The aim of the invention is to configure such a method in such a way that this method in particular meets requirements for preventing/limiting the development of explosive atmospheres in working areas and for reducing measures from previously otherwise typical requirements for Ex zones. This aim is achieved in that a circuit carrying coolant is divided into small volumes that have stop valves and a relief valve, wherein a leak detection diagnosis can be carried out by means of a pressure sensor that can be integrated.

Abstract: A broadband light source with a sufficiently long coherence length is impinged on the optical cavity. The broadband laser light reflects from the first and second surfaces of the cavity. The two light beams, either reflected or transmitted, are phase shifted from one another by an amount proportional to the optical path length of the cavity and inversely proportional to the wavelength of the light (4?nd/?) The two light beams interfere with each other and form a modulated light beam that has a spectrum approximately like the laser's broadband spectrum multiplied by a cosine with a frequency 4?nd/?. The modulated light beam is coupled to a spectrometer that measures the intensity of the light as a function of wavelength over a range of wavelengths. The Fourier transform of the spectrum contains a peak that is related to the OPL and is located at 2*n*d where n*d is the OPL.

Abstract: A hexapodal machining center comprising a fixed frame (1) and a support (2) which are interconnected via six struts (3) of an adjustable length. The connecting points (T1, T2, T3) of three struts on the support form a first working plane, whereas a further working plane is formed by the connecting points (T4, T5, T6) of the three further struts on the support. The frame connection points (G1, G2, G3, G4, G5, G6) of the struts are also arranged in two separate working planes. The connecting points of the two working planes of the support are superimposed such that the connecting lines of the superimposed pairs of connecting points (T1, T4; T2, T5; T3, T6) extend in parallel with each other. This allows a high degree of movability of the support in all of the six degrees of freedom. In particular, the movability in the three rotational degrees of freedom and the force receiving capacity of the support are optimized.
