Abstract: A method for removing aqueous sulfuric acid from solids is presented. By providing an organic solvent inert, and insoluble, to aqueous sulfuric acid and subjecting solids, containing aqueous sulfuric acid, to the insoluble solvent results in a lower phase of aqueous sulfuric acid and an upper phase of solids contained within the solvent. Each phase is then separated from the solvent. The organic solvent must be of density less than the aqueous sulfuric acid and of density greater than the solids. The upper phase of the solids are sugars or lignins created from hydrolysis of a biomass. The lower phase of aqueous sulfuric acid, freed from the solids, contains about 70% sulfuric acid and is available for recycle for hydrolysis of a biomass. Thereby aqueous sulfuric acid is recovered from solids containing aqueous sulfuric acid, and solids substantially devoid of sulfuric acid, are formed.

Abstract: A method and apparatus for easily and inexpensively coupling slides together. A spring that couples to one slide engages an opening in an adjoining slide to latch the two slides together in a fully extended position. The spring includes a protrusion that is angled on one side and that is abruptly raised on the other side. The two slides are easily coupled by engaging angled edges of the two slides and moving the slides together. As the protrusion reaches the opening, the force of the spring causes the protrusion to enter the opening such that the slides are in the latched position. Continued movement causes the angled side of the protrusion to contact the side of the opening and moves the protrusion out of the opening, allowing the second slide to be moved into the unextended position. Thereby slides are easily coupled together without the use of any tools. In addition, the slides are easily uncoupled by deforming the spring and moving the slides lengthwise.
