Abstract: A distributor module for a process plant, in particular an air-separation plant, which can be connected by means of fluid lines to a main-air-compressor arrangement, at least two adsorbers, each of which can be operated in an adsorption phase and a regeneration phase, and a main-heat-exchanger arrangement, comprising a compressor connection, comprising, for each adsorber to be connected, a pair of connections having a first adsorber connection and a second adsorber connection, comprising a first heat-exchanger connection and a second heat-exchanger connection, and comprising a residual-gas connection or a residual-gas outlet; and a valve-and-flap assembly which is designed to act, according to choice, for each pair of connections, in a first state of the pair of connections, or; in a second state of the pair of connections.

Abstract: This description refers to a device for analyzing the most important environmentally relevant substances, such as CO, HC and NO, that are present in vehicle exhaust emissions. It is based on the principle of IR gas absorption. This involves producing measuring signals and a reference signal in a measured optical length (stainless steel tube), with the aid of an infrared source and detector. The production of a ratio then gives a reading and a warning signal is produced whenever a certain limit value is exceeded. The OBM system is made up of modular components, such as a sampling device, exhaust gas processing unit, analyzing device and evaluation unit, which are built into the vehicle. The fluctuating conditions present in the vehicle are compensated for by robust construction and correction of temperature drift by means of production of the first derivation and readjustment of signal strength using an electronically regulated amplification control.
