Abstract: A box for shipping fruits, vegetables, etc. is composed of[a] two pairs of substantially square or rectangular generally flat side panels of generally equal shape;[b] the longitudinally upper edges of the panels being turned outwardly and the longitudinal lower edges being turned inwardly so as to mesh with each other upon storage of the boxes in piles,[c] abutting corner sections of each panel being turned outwardly at an obtuse angle along most of their vertical length, the upper ends of the corner portions thus forming an enlarged base when the boxes are piled up upon each other, and[d] a continuous straight channel extending parallel to and above the lower edges of the box adapted to receive a bottom member.

Abstract: A mixture of a fibrous material and a hot-setting binder is formed and subjected to the action of a high-frequency electromagnetic field. The mixture is subsequently cold molded and may then be hot molded. The alternating field slightly heats the binder thereby lowering its viscosity and, in addition, causes the moisture and the binder which are entrapped in the fibers of the fibrous material to be displaced towards the surfaces of the fibers. These effects lead to an improvement in the cold-adhesiveness of the mixture.

Abstract: The nonflowing molding materials are blown into the mold cavity which has a screen defining one surface of the article to be molded. The materials first fill up the remote areas of the cavity as the carrying air vents through the screen. As the cavity fills up to the feeding nozzle, a vent flap in the nozzle body opens up, allowing the carrying air to vent through the screened opening exposed by the flap until the mold is completely filled and the air is cut off.

Abstract: The wall system has various wall elements which can be erected and taken down, to create various kinds of partition walls. Each wall element is composed of two parallel but spaced particle-board panels which are connected and have interposed between a sound-absorbent and heat-retardant material.

Abstract: A mixture of fibrous material and a thermosetting binder is pressed in unheated state at a working station to convert it into a semi-finished body having approximately the shape and size of the desired shaped article, and thereupon the semi-finished body is pressed at the same working station but under application of heat, in order to convert it into the desired shaped article while setting the thermosetting binder.
