Abstract: One example of this application provides the only portable hard cover (hot tub cover) on the market. One example of this application provides 2 caps per molding (instead of one cap). These are big advantages for consumer and reducing manufacturing cost. Different variations have been presented here, as well. In one application, we introduce a new hinge (and the related system) for the hot tub cover. In one example, the cover is too heavy. To remedy this, we have developed a spring lever that can be used for hard covers of various sizes and weights, because we can put different strength springs inside, to compensate for the weight differences, in different situations. This is much safer and easier for the user.

Abstract: A cover suitable for use on a liquid containing reservoir. The cover is composed of an envelope of porous material. The envelope is subdivided into discrete independent compartments. The compartments each have access to the internal volume for purposes of receiving a charge of hollow spheres. A centrally disposed collection member is positioned at the intersection of the independent compartments. This position is effectively the centre of mass of the cover once charged with spheres and permits expedited positioning and adjustment of the cover on the surface of the liquid container. The independent compartments facilitate controlled consolidation of the spheres therein and allow for simple positioning and removal of the cover which was challenging with prior art arrangements. The latter typically had to be folded or rolled causing manipulation difficulties and causing potentially hazardous situations during manipulation.
