A method of manufacturing a shoe lining having anti-microbial properties. The method comprises providing a quantity of a thermoplastic resin including an inorganic zinc-based anti-microbial agent admixture having a predetermined microbial inhibition characteristic. This thermoplastic resin is blended with a polyethylene resin to form an anti-microbial feedstock. The anti-microbial feedstock is formed into relatively long, narrow, thin lengths of anti-microbial members. These members are woven into an anti-microbial fabric having predetermined microbial inhibition characteristics. This fabric is cut into a plurality of pieces in accordance with a predetermined pattern and the pieces are joined together thereby constructing the anti-microbial shoe lining.

A semi-continuous process for combusting coke from catalyst particles in a fixed bed is improved by injecting combustion air for the regeneration section to the three places, upper air to the burn zone, middle air to the chlorination zone and lower air to the burn zone. By this method combustion gas is added the halogenation gas loop which circulates chlorination gas around the chlorination zone in substantially closed system. Any gas that leaves the chlorination zone flows into the burn zone from the chlorination zone. Thus, passing additional air to the chlorination zone increases the oxygen concentration of the chloriation gas to that additional oxygen-containing chlorination gas and chlorination gas with a higher oxygen concentration passes into the burn zone from the chlorination zone. This method adds air for coke combustion and improves platinum dispersion in the halogenation zone.

Disclosed is a method for manufacturing flexible containers for use in transportation, storage and handling of flowing materials wherein one edge of a length of flexible sheet material is positioned on a cylindrical mandrel. Next, the edge is affixed to the mandrel with a first length of double-backed adhesive tape and extending the double-backed adhesive tape beyond the width of the sheet material and onto the ends of the mandrel. The mandrel is then rotated to wrap the sheet material about the mandrel to overlap and adhere to the first length of adhesive tape to form the first cylindrical wall. A second length of double-backed adhesive tape is applied on the exterior of the sheet material extending from the first wall. The mandrel is rotated to wrap the material about the first cylindrical wall to overlap and adhere to the second length of adhesive tape to form a second cylindrical wall. The sheet material is severed at the edge of the second wall. The first wall is gathered at one end and is tied. The second wall is gathered at said one end and is tied. An adhesive material is applied to the exterior of said second wall adjacent said first end. A filament is wrapped in a helix about said second wall and adhesively attached to the second wall. A sling is positioned around the exterior of said second wall with the gathered ends of said first and second walls within first and second concentric circular portions on said sling, and with support loops joined to said circular portions and extending along the exterior surface of the second wall. An outer covering is adhesively attached and around the exterior of said sling. According to a second embodiment, the inner and outer walls are formed on said mandrel by positioning first and second concentric cylindrical walls on said mandrel, and thereafter performing the steps of the first embodiment.
