Abstract: A container assembly comprising a container, a closure covering an opening of the container and including a skirt, and a tamper-indicating band overlying the skirt and fastened to the container. The band comprises an array of obliquely slanted score lines spaced apart from one another. The score lines define a plurality of obliquely slanted, fracturable strips. Removal of the closure from the container involves grasping the band and manually twisting, thereby breaking or visibly distorting at least one of the strips.

Abstract: A Darrieus-type vertical axis wind turbine is disclosed which includes a vertically extending rotor tube mounted on a support structure with two or three rotor blades of troposkein configuration on the rotor tube for rotating the tube in response to wind energy and thereby drive a generator to produce electrical power. The turbine includes an erection hinge which permits assembly of the rotor tube and blades at close to ground level followed by upward hinging of the rotor assembly to a vertical position. It also includes a system for automatically lubricating the top bearing upon erection and a system for visually tensioning the guy cables.
