Abstract: The present invention relates to a method and an apparatus for removing and recovering organic substances, primarily solvents, from industrial ventilation air contaminated with such substances. The invention is based on the adsorption of solvent in an adsorbent comprising macroporous polymeric particles upon passage of the air through a movable, so-called fluidized bed (2, 3) of the polymeric particles. These particles are fed continuously through the bed under the influence of the air and are then fed continuously into a desorption column (8), in which the solvent is desorbed from the adsorbent, stripped with the aid of heated air and drawn off to a cooler (14).

Abstract: An error-checking system in which two substantially identical modules are checked by comparing the outputs (43, 63) from the chip logic (41, 61) on each modules with each other. One module is designated a master and the other module is designated a checker. The compare logic (46 or 66) is functional only when the module that it is on is designated as the checker. A control bit designates a module as either a master or a checker. A second control bit indicates when in a first state, that a module designated as a master drives the bus, and when in a second state that a module designated as a master and a module designated as a checker alternately drive the bus. Circuitry distinguishes a warm initialization from a cold initialization. A bit in a register causes a module designated as a master to become a checker upon every alternate warm initialization, so that the module alternates between being a master and a checker only each time a warm initialization occurs.
