Granted: 1986-02-26
Abstract: Stock feed was prepd. from a leather waste which was processed by an acidtreatment. Thus, 100kg of leather wastes were percolated through a soln. of 500g of white clay for 3hr. to give activated leather. After removing the white clay by dehydrogenation, the activated leather was treated with a soln. of 0.5% H2SO4 or lactic acid, and then dehydrated in a compressosr to remove the impurities (sulfur compds., chromium, etc.) of the leather. After adding oil and fat, the acid-treated leathers were fried 1 hr at 150≰C in a vacuum- cooker. The oil, fat, and soluble impurities, contaminating the leather, were extracted with a nucleic acidsolvent and evaporated by heating with steam to give fried leather. These leathers were dried by passing through hot-air of 100-120 ≰C and pulverized to give a finely powdered prepn.

At least one of the bending platens (24) is deformable and includes an actuator (32) for deforming the platens from a planar shape to a bent shape to bend the heated glass sheet. Said one platen (24) includes quench openings (42) that move with said platen during the deformation of the platen and subsequently supply quenching gas to temper the bent glass sheet (22).
