Abstract: A method for connecting a screw and a rotary tool in a rotationally fixed manner, wherein the drive surfaces of the driving profiles have a constant inclination relative to their profile axis, which is the same for all drive surfaces of both components. In the component with the outer driving profile, the drive surfaces are all concave or all convex, and in the component with the inner driving profile, the drive surfaces are curved complementary to the drive surfaces of the outer driving profile, in such a way that, in the plugged-together state, the drive surfaces of the two components, viewed in the circumferential direction, come into surface contact/engagement with one another on both sides of the apex of the concave/convex curvature. The driving profiles are designed in such a way that they do not come into contact with each other in the transition regions located between the drive surfaces.

Abstract: A bracket system creates a cost-effective way to build large clear spans in shipping container structures. The system efficiently joins four shipping containers along the longitudinal corner edges, with the containers set adjacent one another, to create a compound beam made by combining or coupling both top rails of the two lower containers and bottom rails of the top containers. A single T-bracket mounts onto pre-installed angle brackets on the raised containers, and a fastener is set through the lower plate to the T-bar joining the lower containers. The bracket system may be iterative and used to combine multiple pairs, or single, containers on top of or beside the initial set.
