Abstract: The invention provides a novel thermoplastic molding process useful in the manufacture of hollow, deformable thermoplastic articles such as hollow doll heads. In the process of the instant invention, a parison is formed at a first injection station and is transferred to a blow mold station. At the blow mold station, the parison is transformed into a hollow, deformable thermoplastic article through application of a vacuum and gas injection. Articles made by the process of the instant invention have a highly realistic appearance and texture.
Abstract: The invention provides a propulsion, braking and anti-rollback control assembly for use in manually propelled vehicles such as wheelchairs. In one embodiment, the invention provides a wheelchair with a control lever assembly and related force conveyance connecter that propel, brake and steer the wheelchair in a mechanically advantageous way while minimizing rollback. A seat-activated auxiliary braking system is also provided. Additionally, the invention provides a selective anti-rollback disengagement system that facilitates selective rollback.
