An aseptic or sanitary diaphragm valve has a valve body and at least one cylinder-actuated valve mechanism. A chamber is defined between a cylinder head and a plate or disk, which has a central bore or passage. A flexible diaphragm extends across the cylinder below the plate or disk. A piston within a cylinder is connected with a valve member foot portion, with a stem passing from the foot portion, penetrating the diaphragm, and passing through the bor or passage to the piston. A compression spring urges the piston to either its raised or lowered position, and air pressure may be used to lower or to raise the piston and the associated valve foot. An aperture in the cylinder can reveal a compromise of the diaphragms.

ActiveUS20080143989A1Reliable regulationPhotometry using reference valueLaser detailsPulse energyRadiation pulse
The invention is directed to a method and an arrangement for stabilizing the average emitted radiation output of a pulsed radiation source. It is the object of the invention to find a novel possibility for stabilizing the average emitted radiation output of a pulsed radiation source which enables a reliable regulation even when there is no sufficiently reliable manipulated variable for influencing the emitted pulse energy (Ei). According to the invention, this object is met in that the individual pulse energy (Ei) of the current radiation pulse is measured, the deviation of the current individual pulse energy (Ei) from a previously determined target value (E0) is determined, and the pulse interval (Δti+1) preceding the triggering of the next radiation pulse is controlled depending on the magnitude of the deviation between the current individual pulse energy (Ei) and the target value (E0) of the pulse energy.
