    摘要: A carton having a bottom, end and side walls, and a two part top, the top having slots receiving locking tabs on the side walls for maintaining an interlocking slotted relationship therebetween. The bottom, side and end walls and top parts are integral, formed of one piece of material with the top parts and end walls wider than the width of the bottom, so as to overlie and be supported by the side walls.

    摘要: In a method of removing carbonyl sulfide from propylene by hydrolysis over a catalyst comprising platinum sulfide on alumina, the improvement comprising regenerating the catalyst by contacting the catalyst with a solvent for polypropylene under conditions such that any polypropylene on the catalyst will be readily dissolved. Specifically, the propylene is passed through, successively, a C.sub.3 -splitter, a heater, the platinum sulfide catalyst bed, and a topping still where resulting H.sub.2 S and CO.sub.2 are separated from the purified propylene. A preferred solvent is liquid propylene.

    摘要: A rim seal is provided for a floating roof tank to fill the space between the floating roof and circumferential wall of the tank. The seal is a compressible toroid of approximately the diameter of the tank and has a cross-sectional diameter greater than the largest opening between the floating roof and the circumferential wall or an existing seal and the circumferential wall. An inner tube is provided which encapsulates the toroid; an outer tube is provided which is elastic and encapsulates the inner tube. Slits in the outer tube adjacent to the circumferential wall are disposed substantially circumferentially with respect to the toroid.
