A lightweight solar concentrator of the reflecting parabolic or trough type is realized via a thin reflecting film, an inflatable structural housing and tensioned fibers. The reflector element itself is a thin, flexible, specularly-reflecting sheet or film. The film is maintained in the parabolic trough shape by means of a plurality of tensioned fibers arranged to be parallel to the longitudinal axis of the parabola. Fiber ends are terminated in two spaced anchorplates, each containing a plurality of holes, which lie on a desired parabolic contour. In a preferred embodiment, these fibers are arrayed in pairs with one fiber contacting the front side of the reflecting film and the other contacting the back side of the reflecting film. The reflective surface is thereby slidably captured between arrays of fibers, which control the shape, and position of the reflective film. Gas pressure in the inflatable housing generates fiber tension to achieve a truer parabolic shape. A plurality of bridges and or retention clips may be employed in certain embodiments to maintain the position of the reflective surface relative to the fibers.

A method for intermittently applying thin-film coatings is realized, by which a coating of extremely thin film reduced to 20 μm or less in thickness is deposited intermittently with high productivity and at the same time, the trailing coating edge of the thin film is formed in a highly accurate shape having good linearity. This is achieved as follows. A band-shaped substrate (1) traveling in one direction is kept looped over a stationary reference-roller (4) and a movable actuation roller (7), and is brought into contact with an application roller (19) which carries a coating agent (18) on its circumferential surface and rotates in a direction opposite to the direction of travel of the substrate (1). The actuation roller (7) is moved to come into or out of contact with the substrate (1) with a predetermined timing. A tension roller (8) is also controllably moved to come into or out of contact with the substrate (1), following the actuation roller (7) coming into or out of contact with the substrate (1), so that the tension applied to the substrate (1) is kept constant all the time.

The present invention relates to a ratcheting unit enabling for securing cargo particularly for tightness in order to secure a load of cargo quickly and safely. Typically these ratcheting straps feature a first end with one length of strap secured to the first end via a bolt, and the other length of strap is fed through a ratcheting cylinder. The ratchet allows the user to hook the straps on the distal ends to a secure anchor point, i.e. the side of a trailer. The straps are pulled taught, the loose strap is fed through the ratcheting cylinder and the ratchet handle is used to tighten the slack in the strap, bringing the strap to a higher tension than what one could easily achieve without the aid of a ratchet to hold the tension and provide leverage for taking in further slack.

A meshless foil stencil frame removes all the components of mesh mounted frames and associated issues and mechanically attaches the foil to an aluminum frame by way of pre-cut tabs. Tension is applied by either pulling on all four sides of the frame and then placing a spacer at each corner to maintain the displacement of each frame member or locking the corners and placing a displacement insert between frame and foil. This displacement in turn applies pressure on a foil which is held firm at each of the four edges and therefore creates tension on the foil.

An arrangement of fenders nested together for compact storage, the fenders including two or more cylindrical bodies having a cavity accessed through the fender top, the fenders being similar shape but graduated in size such that the cavity of a larger fender tensionally receives the next smaller sized fender, the outer diameter of the smaller fender equal to the inner diameter of the larger fender cavity. A fender has a rigid inner core surrounded by a compressible shell made of foam or similar material. The inner core has attachment points for a rope or line. The smallest nesting fender in the set has a cavity diameter sized to fit a commercially-available, off-the-shelf fender. The fenders may be separated and deployed at individual locations on a vessel, or kept together and deployed as a single fender capable of absorbing a greater impact than any of the fenders individually would absorb.
