Abstract: A washing solution for the absorption of carbon dioxide is provided. A method for separating carbon dioxide out of a flue gas of an incineration plant is also provided, wherein at least one alkali metal oxide is added as an oxidation agent for nitrites to a washing solution having an amine-containing absorption agent, the flue gas is brought into contact with the washing solution prepared in this manner and the contained carbon dioxide is absorbed, and wherein the washing solution is then heat-treated and the carbon dioxide is desorbed. A corresponding washing solution having an amine-containing absorption agent and having at least one alkali metal oxide as an oxidation agent for nitrites is also provided.

Abstract: The invention relates to an apparatus (1, 101, 201) for electrochemically coating a workpiece (22), including a coating reservoir (2, 102, 202) with a charge opening (5) and a supply reservoir (3, 103, 203), wherein the two reservoirs are in communication through a passage opening (4, 104, 204). The apparatus has at least one electrode (11) and one counter electrode (14). In order to prevent contamination of a coating liquid (20, 120, 220) during an electrochemical deposition process, the apparatus can be switched between a coating position and a rest position by rotating the supply and the coating reservoirs about at least one common axis (A, A?, A?) so that the center of gravity of the volume of the coating reservoir (2, 102, 202) in the coating position is lower in relation to the center of gravity of the volume of the supply reservoir (3, 103, 203) than in the rest position. The invention further relates to a method for coating workpieces.

Abstract: A rotary floor machine having a base, a pole handle, a pole structure, a handlebar, a trigger bar, and a lock-out device. The pole handle is pivotally secured to the base and is movable between a vertical position and a rear angular position. The pole structure is secured to the pole handle. The handlebar is secured to the pole structure so as to be substantially perpendicular to the pole handle. The trigger bar controls the starting and stopping of the rotary floor machine and is mounted to the handlebar so as to be movable between proximate and distal positions relative to the handlebar. The trigger bar starts the rotary floor machine when in the proximate position and stops the rotary floor machine when in the distal position. The lock-out device has an element that is movable between a blocking position and an un-blocking position in response to movement of the pole handle between the vertical position and the rear angular position.

Abstract: A wall capable of rapid assembly and dismantling is disclosed, which includes a plurality of detachable boards, each of which are connected to at least one other of such detachable boards on an adjacent facing side. Coupling elements for connecting each of the plurality of detachable boards to another of such board are included, each of which permit at least a part of the facing sides of the plurality of detachable boards, which extend in a vertical direction, an infinitely variable swiveling action about an axis extending parallel to the facing sides of the plurality of detachable boards. The coupling elements extend perpendicularly to a swiveling axis and in the direction of the swiveling axis and are fastened edgeways laying flat to each of two detachable boards which are adjacent one another. The coupling elements act as a spacing piece along the facing side of each of the detachable boards and extend perpendicular to the swiveling axis.

Abstract: A wet/dry vacuum cleaner which has a rotatable air directional valve and a piping arrangement whereby the air can be either directed into the tank for pumping out a recovered liquid solution or admitted directly to the tank through an internal flapper valve and expelled around the periphery of the vacuum when functioning as a dry vacuum cleaner.
