    Abstract: A method of joining the abutting ends of tubes together in a manner that provides a weld having good pulling, bending and thickness reduction capabilities. The method comprising the steps of providing the tube ends with complementary angle cuts, the angle of each cut being less than 90* with respect to the axes of the tubing; placing and maintaining the cut ends of the tubes in mating, abutting relationship, the abutting ends providing an interface therebetween that is disposed at the same angle, with respect to the tubes axes, as that of the angle cuts; disposing said interface adjacent a welding head; and welding the tubes together along the mating, abutting ends.

    Abstract: A hollow ball bat having a tubular bat body provided with a handle portion, a barrel portion and a connecting portion. A tubular paperboard dampening element secured to the interior surface of the barrel portion and having an external surface in engagement with the barrel portion interior surface. Such engagement may include about 30 to 75 percent of the barrel interior surface. The paperboard tube may be provided with corrugations on its exterior surface and may have a length of about 3.5 to 9 inches. The ball bat has an end closure closing the barrel portion and the dampening member is secured to the end closure. In a preferred form, the end closure is an end plug having a reduced diameter lower portion which extends into the dampening member.

    Abstract: A method for closing and/or sealing an open top container without subjecting the container to objectionable axial compressive forces. A closure having a skirt which forms a downwardly opening annular recess or groove and having a bead at the end of the skirt, is constrained against movement while the mouth of the container is moved upwardly into the groove. An inwardly acting compressive force then crimps the closure against the neck of the container, either by embedding the bead in the wall of the container or by gripping the wall of the container above the closure bead or by both. One form of apparatus for carrying out the method is illustrated in the drawings.
