    Abstract: A nozzle for injecting viscous fluid such as a thermoplastic into a mold cavity of a mold body includes a tip section and a nozzle body secured thereto. The tip section serves as a sprue of the mold body. The mold body includes a core portion, a cover portion and a clamp plate for securing the core portion to the cover portion. The nozzle body having an inlet end, a discharge end, which communicates with the tip section, and a flow passage for viscous fluid extending from the inlet to the discharge end. A valve element is mounted for reciprocation in the nozzle body flow passage to control the flow of viscous fluid through the nozzle body discharge end. At least the tip section of the nozzle body is located in the mold body cover and the nozzle body is substantially positioned between the mold body cover and the clamp plate. The valve element can be a shut-off needle which is disposed for reciprocating movement in the nozzle body flow passage. A shut-off pin can be disposed for reciprocating movement in the non-viscous fluid flow passage of the shut-off needle to control a flow of fluid through the non-viscous fluid flow passage.

    Abstract: Disclosed is a foldable rear top particularly advantageous for use with vehicles having a "fast back" configuration or vehicles having a roll bar or T-top arrangement. The foldable top includes a rigid center panel and a pair of side panels positioned to enclose the rear compartment of the vehicle. The center panel is foldable downwardly pivoting from a position near the rear of the vehicle. The folding mechanism also includes means to simultaneously fold the side panels inwardly underneath the center panel as the top is lowered from the raised position.
