Abstract: Methods and systems are presented in which one or more heavy-duty straps are positioned in contact with a top and bottom of a door and engaged with a heavy mechanism exerting a static tension greater than 10 newtons. A user can exercise using removable extenders attached to any of several loops at various vertical positions, creating enormous leverage along the strap(s). Supplemental cushioning may be utilized to minimize damage from large kinetic energy imbued upon components of the methods and systems during or after exercise.

Notwithstanding large kinetic energy imbued upon components during or after exercise as described herein, damage may be minimized by supplemental cushioning.

Abstract: A method for forming a threaded dispensing opening for a cylindrical drum container having a generally flat circular closed bottom, a generally flat circular closed top, and a cylindrical side wall comprising the steps of forming an aperture in the drum top and drawing the drum metal adjacent the aperture upwardly to define an upwardly extending annular shoulder. The shoulder is then compressed downwardly to thicken the shoulder and a female threaded portion is formed on the inside of the annular shoulder which is receptive of a threaded closure member.

Abstract: A drum testing apparatus simultaneously tests the bottom chine, sidewall vertical chine, and wall integrity of a typical drum, such as a 55-gallon drum. The apparatus includes a frame for supporting the drum to be tested in a generally upright position. A turntable base is moveably supported by the frame and provides a rotatable surface for supporting and turning the drum at its bottom end portion. A reservoir immerses the drum bottom chine and the top chine during testing and while the turntable base rotates the drum. A liquid spray simultaneously immerses the drum sidewall and the vertical chine during testing and while the drum rotates. A holder including a pair of spaced-apart flanged portions engages respectively the top end portion and the bottom end portion of the drum and preloads the drum end portions to prevent removal of the drum end portions during testing. An air pressure source pressurizes the drum interior during testing.

Abstract: There is provided a method and apparatus for testing drums such as steel drums, wherein the drums are moved automatically into a pre-determined area, and the drums are rotated and oriented, air under pressure is next introduced into the drums, and wherein after an operator observes the drums for leaks, the drums are mechanically lifted from a water filled area. The method and apparatus can be utilized as a dum submerged tester for handling a plurality of drums, or the method and apparatus can be for a single drum submerged tester.
