摘要： A process for removing SO.sub.2 from a fluid containing SO.sub.2 by employing as an absorbent for the SO.sub.2 an admixture of water and a compound represented by Formula I: ##STR1## wherein each R.sup.1, R.sup.2 or R.sup.3 is independently hydrogen; an alkyl group; a carboxylic acid group; a hydroxyalkyl group; an aldehyde group; and alkyl group containing a carboxylic ester, a carboxylic acid or salt, ether, aldehyde, ketone or sulfoxide group; wherein at least one R.sup.1 or R.sup.3 is carboxy methyl group and at least one R.sup.1 or R.sup.3 is hydrogen, preferably at least one R.sup.1 is carboxy methyl and at least one R.sup.3 is hydrogen. The absorbent solution preferably can be thermally regenerated by heating to remove SO.sub.2.

摘要： The 2-piperazinones are made by reacting a 1-cyano-1-hydroxyalkane with ethylenediamine or a substituted ethylenediamine in aqueous solution. The process to make the 2-piperazinones suitable as a regenerable sulfur dioxide absorbing medium requires that the cyano compound be present in at least a molar equivalent amount to the diamine and that the resulting 2-piperazinone product be sparged with an inert gas.

摘要： The invention is an improvement in a process for making cellulosic articles said process involving a separation of cellulosic material from a mixture containing a liquid, metal cations, and cellulosic material. The improvement involves adding to the mixture at least one retaining material which binds at least one metal cation and, in the separation, is retained with the cellulosic material. Suitable retaining agents are either organic or inorganic and include chelate-forming polymers, both synthetic and natural, colloidal suspensions of inorganic compounds, and mixed metal hydroxides. In each case, the metal cations remain in the cellulosic article, e.g. paper, rather going into waste water from which they would otherwise need to be removed.

摘要： Magnesium is separated from magnesium slag containing radioactive thorium and its daughters by solubilizing magnesium from magnesium slurry using carbon dioxide and separating magnesium from magnesium slurry containing thorium and its daughters by filtering. The process concentrates the radioactive thorium and its radioactive daughters from the magnesium slag and reduces the volume of the radioactive waste that requires disposal.

摘要： A vehicle is provided with a seat oriented in a passenger compartment forward of a storage compartment. The seat has a seat back that is pivotally connected to a body of the vehicle. The seat back is pivotable between a seating position and a storage position. A battery is disposed within the storage compartment. A tray is removably connected to the vehicle body in either one of a first and a second position. The tray is elevated from the battery within the storage compartment in the first position. The tray is connected to the vehicle body such that it is contiguous with and forward of the battery in the second position. A flat load floor is formed by the top surface of a housing of the battery together with the tray.
