    • A method of preparing a catalyst comprising aging a silica support in an alkaline solution to produce an alkaline aged silica support, removing at least a portion of the alkaline solution from the alkaline aged silica support to produce a dried silica support, and activating the silica support to produce a catalyst composition, wherein alkaline aging lowers the surface area of the silica support to less than about 50% of the original value and wherein activation of the silica support is carried out in batches of equal to or greater than about 500 lbs for a time period of less than about 8 hours. A method of preparing a polymer comprising alkaline aging a silica support material, adding chromium to the silica support material prior to the alkaline aging, after the alkaline aging, or both to form a chromium-silica support, rapidly activating the chromium-silica support produce an activated olefin polymerization catalyst, contacting the activated olefin polymerization catalyst with at least one monomer in a reaction zone under conditions suitable to produce a polymer, and recovering the polymer

    • A method and apparatus for the continuous production of green ware articles, e.g. lavatory pans (20), from slip are disclosed. Plaster of paris moulds (10) at least partially reinforced with acrylic, fibreglass, polypropylene or carbon fibres pass through first and second microwave drying ovens (8, 16) on a conveyor system (2). In the first oven (8) a green ware article contained in each mould (10) is at least partially dried. In the second oven (16) the empty re-assembled mould (10) is dried prior to being refilled with slip. Also disclosed are a method of fabricating the reinforced moulds and a self-centering clamping cradle with opposed arms hinged at the base, and a releasable latch, for transporting and holding the mould. The cradle is tiltable.
