Abstract: The present invention relates to a screed for a paving machine that includes a flexible smoothing plate, a vertex block a first actuator, and a second actuator. The flexible smoothing plate is provided with a longitudinal length and an outer longitudinal end. The vertex block is located on top of the flexible smoothing plate. The first actuator is connected to the outer longitudinal end and adapted to selectively adjust an elevation of the outer longitudinal end so that the outer longitudinal end of the flexible smoothing plate forms a berm by flexing about the vertex block and extending upward at an angle relative to an inner portion of the flexible smoothing plate. The second actuator is connected to the vertex block and configured to adjust the length of the berm by selectively repositioning the vertex block along the longitudinal length of the flexible smoothing plate.

Abstract: A door system comprises a door panel, a support member, and a pivoting vertical plate. The door panel comprises a plurality of discrete rigid insulation pieces interposed between flexible layers. An outer skin encompasses the rigid insulation pieces and the flexible layers. The door panel is secured to the support member by the outer skin, such that the outer skin bears the weight of the door panel. The vertical plate is secured to a trailing side of the door panel. The vertical plate includes keepers that selectively engage hooks extending from a casing positioned at a doorway. The rigidity of the door panel depends on the pivotal position of the vertical plate relative to a plane defined by the door panel. The door panel provides sufficient flexibility to withstand impacts from objects and vehicles yet also provides sufficient rigidity to insulate a cold environment from a warm environment.
