Abstract: The collator (10) sequentially stitches groups (12) of sheets. The collator (10) includes a support surface which extends past a plurality of hoppers (14) to a stitching station (44). Sheets are sequentally fed from the hoppers (14) to form groups (12) of sheets on the support surface (16). A main conveyor assembly (24) sequentally pushes groups of sheets along the support surface (16) to a reject station (72). Groups of sheets containing more or less than a predetermined number of sheets are rejected at the reject station (72). The groups (12) of sheets containing the predetermined number of sheets are moved to a transfer station (32) where they are engaged by a secondary conveyor assembly (36) which moves them to a stitching station (44). 
<??>At the reject station (72), a ramp (84) is movable between a retracted position and an extended position. When the reject ramp (84) is in the retracted position, it cooperates with the main support surface (16) to support a group (12) of sheets containing the predetermined number of sheets as the group moves to the stitching station (44). When the ramp (84) is in the extended position, it projects upwardly from the support surface (16) to the reject conveyor (94). The main conveyor (24) pushes groups (12) of sheets containing more or less than the predetermined number of sheets up the reject ramp (84) to the reject conveyor (94).

Title: Method for producing silica
IPC: C01F7/54
Filed: 1983-09-29
Granted: 1987-04-29
Abstract: The present invention relates to a method for purifying silica waste obtained in the manufacture of aluminium fluoride from hexafluosilicic acid and aluminium hydroxide, whereby the silica, is subjected to an acidic leaching at a pH below 3 to leach out part of the fluorine and substantially all the aluminium present in said waste, and is thereafter subjected to an alkaline leaching at pH 8.5-11.5 to leach out remaining fluorine present in said waste. The teachings are preferably carried out at elevated temperatures, normally 60-90°C, and for a time sufficient to considerably reduce the contents of aluminium and fluorine, normally 1-3 hrs.The silica obtained is highly reactive and can be used as such or transformed into sodium slicate by a reaction with sodium hydroxide. The contents of fluorine and aluminium can be transferred to a process for the production of cryolite or similar compounds.
