摘要： A membrane module for selective gas separation includes one or more separation units stacked one on the other, and at least one of interposed frame plates or stack-end frame plates. Each separation unit includes a support plate with a separation gas receiving structure and at least one corresponding gas separating membrane. The frame plates having a gas mixture flow chamber structure. Each separating unit and the frame plates contain (1) gas-mixture connecting channel structures in a first and a second side area formed by overlapping openings in the plates and extending in a stacking direction, which are in fluid connection with the gas mixture flow chamber structures; and (2) separation gas connection channel structures in a third and fourth side area, which are in fluid connection with the separation gas receiving structure or structures.

摘要： An apparatus for regulating welding parameters during laser beam welding includes a camera for detecting the geometry of a melt bath formed during the welding process. The camera is connected with an image-data-processing unit. The welding depth is regulated by the processing unit as a function of the detected melt bath length or melt bath area. The focus position of the laser beam is regulated as a function of the geometric similarity factor, which is calculated as the quotient of the melt bath area and the distance between the geometric centers of gravity of the laser beam keyhole and the melt bath area. Detection and regulation of gaps between the workpieces of height offset between the workpieces and/or lateral offset of the laser beam is also provided for.
