Abstract: Methods are provided for at least two teams to play a game with a ball on a playing surface having a plurality of zones and at least two goals. Zones have distinct rules for handling passing, receiving, and shooting of a ball during a game. A goal provides two distinctly defined types of scoring zones through which to score the ball from within a peripheral line of the playing surface. One type of scoring zone is at least one open ring shaped opening, and the other is an arced rectangularly shaped opening. The ball may be scored through either of the scoring zones. Points are awarded differently for scoring in either of the two zones and for throwing or kicking the ball through the two zones. Ball comprises at least two panels having arms attached along a contiguous seam.

Abstract: An improvement in the production of low mineral content fuel by coal liquefaction processes which yield as a primary product a mixture of liquid and solids a part of which are suspended in the liquid whereby the separation of the suspended solids is facilitated by the addition of an effective amount of a suitable chelating agent to the mixture. The chelating agent is optionally added as a solution of the chelating agent in a suitable solvent and desirably is present in an amount from about 100 to about 150% of the stoichiometric amount required to react with the suspended solids in the mixture.
