Abstract: An endotracheal tube having utility in one lung ventilation has a curvature of predetermined radius formed in its distal end so that it is easily introducible into a left bronchus or a right bronchus of a trachea. The curvature is produced by first inserting a straight copper tube into the distal free end of a conventional straight endotracheal tube. The copper tube is then bent into the desired radius of curvature and the distal end of the endotracheal tube is inserted into an oven at a temperature of about one hundred seventy degrees to soften the thermoplastic materials of which the endotracheal tube is made. After the thermoplastic materials have softened and conformed to the curvature of the copper tube, the distal end is allowed to cool and the copper tube is then removed therefrom. When cooled, the distal end of the endotracheal tube maintains its curvature when the copper tube is withdrawn due to the thermoplastic quality of the materials from which the endotracheal tube is made.

Abstract: A single facer for corrugated paperboard of the type using a very large diameter fluted bonding roll and a much smaller diameter fluted corrugating roll which engages the bonding roll to provide a corrugating nip. The small diameter corrugating roll is made to be resilient so that it is capable of inward deflection in the vicinity of the corrugating nip in order to cushion impact as the rolls interengage along the corrugating nip. This cushioning deflection absorbs vibrational movement due to chordal action of the interengaging flutes, and thereby reduces noise levels, roll wear and improves the quality and consistency of corrugation.

Abstract: A method for forming a molded grommet using a device which includes a fixed mold and a movable mold, the latter having three positions. The first is a closed position, wherein the two molds are adjacent each other with a middle plate between them. Second, there is an intermediate position in which the middle plate and movable mold are spaced apart from the fixed mold. Third, there is an open position, wherein the movable mold is spaced further from the fixed mold than the middle plate. A core is fixed to the movable mold and, when in the closed position; the two molds, the core, and the edge of the middle plate define the molding space into which moldable resin is introduced, thereby forming the grommet with the edge within the channel. As the core moves from the intermediate position to the open position, the middle plate is retained in the intermediate position; therefore, the core is pulled out of the grommet through the axial hollow therein.
