A method and an apparatus for designing generalized tables. The method and the apparatus are described by a collection of processes for performing operations such as creating a generalized table, deleting a generalized table, drawing a rule, stretching or shrinking a rule, shifting a set of rules, deleting a rule, aligning a rule, unaligning a rule, combining cells, dividing a cell, creating a region, and deleting a region.

Apparatus and method for designing a form structure using column and row

A method of rotationally molding blends of polymers of good flow to produce articles of high impact resistance, high stress crack resistance, smooth surfaces, and the absence of excessive warpage in which the blend is placed in a rotational mold which is then biaxially rotated about two perpendicular axes while heating the mold and contents and then cooling the mold and contents to about room temperature while maintaining this biaxial rotation followed by removing the resulting article. The disclosure also includes the rotationally molded shaped structures resulting from this method with these structures having high impact resistance, high stress crack resistance, smooth surfaces and the absence of excessive warpage.

Method of rotationally molding plastic articles

A three component blend of polymers comprising a polyethylene homopolymer or ethylene-alkene copolymer with an ethylene-vinyl acetate copolymer and either an ethylene-propylene copolymer or an ethylene-propylene-diene terpolymer. These three component blends are particularly suitable for rotational molding of shaped structures as they have synergistic properties of environmental stress crack resistance and high impact strength of the finished products. The disclosure also includes shaped structures comprising these blends.
