摘要： At least one reinforcing member is introduced into a pressure chamber and, from thence, into an extrusion zone through an entry port communicating between the two. Simultaneously, heated extrudent is delivered, from an extruder, to points around the reinforcing member in the extrusion zone where it encompasses the reinforcing member. Continued pressure from the extruder forces extrudent and the encompassed reinforcing member through a die in the front or downstream end of the extrusion zone. Upon emerging from the die the extrudent cools and sets around the encompassed reinforcing member and a reinforced extruded article is the result. The pressure chamber is utilized to prevent extrudent from escaping from the extrusion zone through the entry port provided for the introduction of the reinforcing member. This invention is useful in that it provides a method for incorporating reinforcing members into extruded articles.

摘要： Mechanism for extruding large cross-section articles consisting of a substantially conventional extruder and die arrangement combined with a series of accumulators interposed in communication between, and receiving and temporarily storing extrudant being pumped thereinto from the extruder at relatively low pressure for positioning the extrudant over a much wider die than normal. Hydraulically-operated rams force the extrudant from the accumulators into the die at relatively high pressure for its extrusion into a large scale item.

摘要： A collapsible aircargo container is disclosed which is particularly adapted for aircraft transportation. The container is secured at its lower edges to a pallet on which the products rest within the container. The latter is formed of a double walled airtight rubberized material having a passageway between the walls to receive air under pressure. One or more spring loaded air valves are inserted in the material of the container and communicate with the compartment formed between the double walls. A frame member is also provided, made of a double walled material, to provide an entrance to the interior of the container. The frame, when charged with air under pressure, will stand upright to support the container material and, when devoid of air, can be moved around hinges to be against the pallet. Adjustable straps of webbing material are secured to the outer surface of the container and the frame member so as firmly to secure the contained product to the pallet and to be protected by the container. After the products have been stowed within the container, the pressure of air in the double walls of the container and frame member is reduced to cause the container material to hug or settle down onto the aggregate contour of the products. The container and frame member can be collapsed by complete removal of air pressure when not in use, to occupy a space no greater than the physical dimensions, i.e. thickness and size of the container material and the attached pallet.
