An adjustable deck positioner includes a vertical member having means for attaching to a deck rim and having a pivot arm bracket; a pivot arm assembly having a pivot arm attached to the pivot arm bracket, wherein the pivot arm may pivot between a substantially vertical position within the pivot arm bracket and an extended position angled away from the vertical member; and a lock pin installed across the pivot arm bracket, for constraining movement of the pivot arm towards the vertical member, thereby setting the angle at which the pivot arm extends from the vertical member.

Method and apparatus for raising a floating roof included in a storage tank whereby a first and a first opposite force are applied between a floor in the storage tank and an internal surface of the floating roof. An additional set of forces are also provided and are constrained according to the first and first opposite force, not only in magnitude, but in position. By constraining these forces to be applied orthogonally to the floating roof, horizontal shear forces can be resisted thus reducing the likelihood of failure of a cribbing unit. By increasing these forces, the roof is raised.

A floating cover sheet of a liquid reservoir is configured to rest on the liquid surface and includes a plurality of elongated sheet panels each defining edges and a lower region. The sheet panels are connected to one another and each of the sheet panels has a buoyant carrier sheet disposed in the lower region thereof. The buoyant carrier sheet is made of plastic and defines a carrier surface. A plurality of panel-shaped solar modules are applied to corresponding ones of the carrier surfaces of the carrier sheets. The solar module has a width less than the width of the corresponding sheet panel so as to define, on each sheet panel, a strip of carrier material free of the solar module corresponding thereto and configured to be walked on and to be slip resistant.

A fermentation method and system which includes providing juice to be fermented into a container. The juice having a cap that is a collection of solid components of grapes. The cap has a permeable consistency and floats in the juice. The method includes moving a portion of the juice from below the cap upward into contact with the cap.

Tank lids include a first coated substrate including a first part having a first thickness, a first elastomer coating the first part, a second coated substrate positioned adjacent to the first coated substrate, the second coated substrate including a second part having a second thickness, and a second elastomer coating the second part. A first seam can be formed between the first and second coated substrates to allow for moisture to pass between the first and second coated substrates so that moisture is allowed to seep away from the top of the tank lid.
