Abstract: A rotary energy generating device includes an output shaft, a rotor coupled to the output shaft, and a plurality of paddles coupled to the rotor, with each paddle being moved between vertical and horizontal positions as the rotor is rotated. A chamber housing includes inlet and output pairs. A respective open chamber area is defined between each inlet and outlet pair based on a given rotation direction of the rotor, with each respective open chamber area configured to receive the paddles in the vertical position as the rotor rotates in the given rotation direction. A respective slotted chamber area is defined between each outlet and inlet pair based on the given rotation direction of the rotor, with each respective slotted chamber area configured to receive the paddles in the horizontal position as the rotor rotates in the given rotation direction.

Abstract: A jewelry ring display apparatus includes a platform having upper and lower surfaces with an opening extending therebetween. A first end line attachment is on the lower surface, and a second end line attachment is on the lower surface and positioned so that the opening is between the first and second end line attachments. A line has a first end to be held by the first end line attachment, and a second end to be passed through the opening and inserted through and around a ring to be displayed on the upper surface. The second end of the line is to be passed back through the opening and is to be held by the second end line attachment. The line is under tension when extending between the first and second end line attachments so that the ring can be held in a stationary position with respect to the upper surface of the platform.
