Abstract: Flexible foot apparatuses and methods of using the same are disclosed. In one aspect a flexible foot apparatus is disclosed which can attach to and/or frictionally engage a standard crutch tip. The apparatus can include upper, lower, and intermediate body portions. The intermediate body portion can pivot during crutch assisted walking and can have a diameter smaller than diameters of the upper and lower body portions. The pivoting motion of crutch assisted walking can increase the amount of surface area available to engage a floor by pressing a bottom surface of the apparatus against the floor. Thus, stability at the crutch to floor interface can be improved.

Abstract: Improved process for fluidifying flocculated aqueous suspensions of red muds in the production of alumina from bauxite by the Bayer process, which consists:in dissolving bauxite using sodium hydroxide;then, in decanting and in washing the red muds formed in order to separate them from the alumina in successive vats, while recycling the washing waters upstream;and finally, in eliminating the red muds thus treated;and in which a flocculant (F) consisting of a polyacrylamide of molecular weight greater than ten million is introduced into the suspension of one of the successive vats;wherein a dispersing agent (D) formed by an anionic acrylic acid polymer of molecular weight lower than fifty thousand is added simultaneously with said flocculant (F) to the suspension in the same vat.
