Abstract: An efficient energy accumulation element comprising a compression spring which uses end caps and flexible rope to pre-compress the spring for using in actuators and other devices. The efficient energy accumulation element is independent of external surfaces or end construction of the spring. The accumulation and release of energy happens noiselessly.

Abstract: A portable clothesline system for helping to dry garments, heavy rugs, or blankets featuring a pair of vertical bars positioned parallel to each other and supported by tapered bases and a pair of horizontal bars attached to the top ends of the vertical bars. The horizontal bars are connected via a plurality of wires that extend from one horizontal bar to the other. The wires are secured to the horizontal bars via slots with perforations.

Abstract: A clothesline system comprises at least two separate cables that are independently tensionable through separate cable tensioning devices. The tension devices are attached together to provide for common, parallel movement of the separate cables though the cables are separately passed around separate pulleys at the both ends of the system. The two separate cables add strength to the system. The separate cables are preferably wound in left and right windings to prevent unraveling of the braid of the cable. By providing separate cables, assembly of the system is less complex as the two loops of cable are separate.

Abstract: A clothesline system is provided for automatically applying clothespins to articles to be dried once they are placed on a clothesline. The clothesline system comprises first and second pulleys, which are positioned at a spaced apart distance from each other, as well as a main cable, a secondary cable and a plurality of clothespins. The clothespins are capable of being removably attached to the secondary cable, and are movable between an open and closed position for receiving and gripping articles to be dried to the main cable. The clothesline system further comprises a mechanism for automatically opening and closing the clothespins so that they are able to either selectively grip or release the articles to be dried. Finally, the clothesline system comprises a support system for guiding and supporting the main cable such that the main cable is prevented from sagging beyond an acceptable distance within which the clothespins are capable of being attached to the main cable.
