    摘要： The present invention relates to a process for purifying monomers, by evaporating at least a portion of the monomers present in a starting composition and then condensing it, which is characterized in that at least a portion of the starting composition is evaporated in a short-path evaporator, the mass flow density of the vapors {dot over (m)} being selected according to the relation (I) m . ≤ 1800 ⁢ kg · K mbar · m 2 · h · kg kmol · p i · ( M ~ T ) 0.5 ( I ) in which {tilde over (M)} is the average molar mass of the vapors in the short-path evaporator in kg/kmol T is the temperature of the vapors in K pi is the pressure in the short-path evaporator in mbar {dot over (m)} is the mass flow density of the vapors in kg/(m2·h). A further aspect of the present invention is a plant for performing the process.

    摘要： The present invention relates to a process for purifying unsaturated compounds, said purification being performed in a plant which comprises at least two evaporators which are connected in such a way that a portion of the unsaturated compound is circulated, the vapours condensed in the first evaporator being isolated and the vapours condensed in the second evaporator being introduced into the first evaporator, which is characterized in that the mass flow with which the condensed vapours are isolated from the mixture to be purified in the first evaporator is less than the mass flow with which the condensed vapours from the second evaporator are introduced into the first evaporator.The present invention further describes a plant for performing the process, which comprises at least three evaporators which are connected to one another such that the residue of the first evaporator remaining in the liquid phase can be passed into the second evaporator, the condensed vapours of the second evaporator can be passed into the first evaporator and the residue of the second evaporator remaining in the liquid phase can be passed into the third evaporator, and the condensed vapours of the third evaporator can be passed into the second evaporator.

    摘要： A circuit arrangement, especially for supplying an electromagnetic holding brake with a clocked supply voltage, includes a module for controlled provision of a clocked supply voltage for free-wheeling operation of the holding brake. The module has a switching unit for switching off the supply voltage for braking operation. A free-wheeling diode and a suppressor diode are connected in parallel to an inductance of the holding brake, with the free-wheeling diode being effective in free-wheeling operation only and the suppressor diode being effective in braking operation only.
