Title: Paper corrugation machine guide structure - presses paper continuously against bottom corrugation roller in front of pressure roller
IPC: B31F1/28
Filed: 1977-06-17
Abstract: The self-adjusting guide structure is for a single-pass paper-corrugation machine, having top and bottom corrugation rollers between which the paper etc. is guided. Adhesive rollers move to and from the bottom roller to apply adhesive to the crests of the corrugations as the paper passes round it, and a pressure roller presses a cladding sheet against the crests to which the adhesive has been applied. A number of guides are arranged alongside each other (40), so as to press the paper (10) against the bottom corrugation roller (14) before it passes between the latter and the pressure roller (18). Pressure is generated by a gravity-operated component.

Title: Improved wet scrubbing method and apparatus for removing sulfur oxides from combustion effluents
Inventor: KLINGSPOR S JONAS
IPC: B01F33/40
Filed: 1995-06-07
Abstract: Sulfur oxides (SOx) are scrubbed from combustion effluents with aqueous limestone slurries single-loop, open-tower countercurrent limestone wet scrubbers. Effluent flow rates are greatly increased while L/G values and reaction tank (150) residence times are decreased. Improved entrainment eliminator design, nozzle (112) placement and spacing, and the use of a hydrocyclone (181) to separate and recycle smaller particles of limestone from the byproduct gypsum, facilitate these advantages. Limestone is reduced to very fine particles, e.g. about 8 mu  or less with more than 99 %  of the particle by weight less than 44 mu , and introduced into a scrubbing slurry which is contacted with SOx-laden effluent. Reactivity of the scrubbing slurry is maintained, even at reduced pH, by continuously operating a hydrocyclone to assure a molar ratio of calcium-containing to sulfur-containing compounds of greater than about 1.3 to 1 while keeping both a low chloride and low non-reactive solids content. The hydrocyclone removes large particles of calcium sulfate and provides a recycle stream (184) of fine calcium carbonate and non-reactive solids which is bled off as necessary to maintain both the desired low chloride and non-reactive solids levels.
