Abstract: Powdered starting material utilized for molding (e.g., rotational molding, injection molding, blow molding), extrusion, and the like can be preheated to reduce the time required to complete the processing of the material. After being preheated to a temperature below a melting temperature of the powder, the powder is transferred to a processing station. For example, in a rotational molding system, the preheated powder is transferred to a mold, where the preheated powder is melted and the mold is rotated such that the molten material adheres to the walls of the mold. After obtaining a desired distribution of the material over the walls of the mold, the temperature of the mold is decreased as rotation of the mold continues. When the article is sufficiently cooled, the article is removed from the mold.

Abstract: An on-board battery recharger is provided for use on a toy-riding vehicle that automatically connects and disconnects the recharger to the battery of the vehicle. A power cord is also provided to connect power from a power source to the on-board recharger via a receptacle. When charging power is supplied to the toy vehicle, an electric switching means connects the battery to the recharger and disconnects the battery from drive motors that propel the toy vehicle. Likewise, when the charging power is removed from connection with the toy vehicle, the electric switching means disconnects the battery from the recharger and reconnects the battery to the drive motors for continued operation of the toy.
