Abstract: A wheeled work machine has a cab that is assembled with side panel assemblies that are each formed from two mating die formed side panel sections so that smoothly curved shapes, and recessed cross sections can be made. When the two panel sections are rigidly joined together, they form strong, bend and torsion resistant box sections for structural members around an operator access opening, as well as around an accessory opening. The inner one of the die formed panel sections includes flanges that extend inwardly toward the center portions of the cab for supporting cross panels such as seat supports, a roof, and a dash board assembly. The side panels and cross members are spot welded together to form a quickly made, smooth appearing, and very strong operator cab.

Abstract: A process and apparatus for rapidly expanding and molding carbon dioxide-impregnated polymer particles is disclosed. The process involves expanding the impregnated particles in a moving stream of pressurized saturated steam or super-heated steam, directing the resulting stream of pre-expanded particles into a mold, and molding the particles into a foamed object. Apparatus suitable for use with the process is also disclosed.

Abstract: A friction or inertial welded cylinder is made of a tube and base member. The base member has an annular groove that is positioned within the cylinder tube and which receives the kerf formed on the interior of the cylinder during welding. The groove height is formed to provide a place to receive the kerf as it curls and to seal material within the groove so foreign materials do not later break loose from the kerf and cause damage to the cylinder assembly in use.
