Abstract: An apparatus and method for enhancing the transfer of heat in a fluid within a reservoir. The interposition of heat exchangers between a primary heating arrangement and an auxiliary heating arrangement results in greater utilization efficiency in heat transfer to the fluid within the container. A predetermined arrangement of heat exchangers within the reservoir containing the same is also disclosed.

Abstract: A connection arrangement for connection of vertically and/or horizontally arranged containers. Each of the containers provides bosses or projections over a collinear pair of which is placed a separate plate. The plate provides matched polygonal apertures to receive the projections. Each of the projections provides an aperture there through to receive a retainer pin or bolt. The pin or bolt abuts the plate when engaged. The arrangement greatly expedites the separation of the containers when desired. The user needs only tap out the retainer pin and pull off the plate. This obviates the use of fasteners which can freeze, rust or become otherwise inoperative or cumbersome.

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.

Abstract: A liner system and method for installing the liner. The liner is composed of a synthetic material (HDPE or LLDPE). The liner has a base and walls and an undersurface. The undersurface includes integral therewith a plurality of discrete and independent radially disposed in spaced relation stabilizing members. The stabilizing members are exposed when the walls of the liner are positioned in a substantially vertical orientation relative to the base. This exposes the stabilizing members. The container may then be positioned in segments on top of the stabilizing members with the walls of the liner adjacent a wall of the container. In this manner, the container structure is fabricated about the liner. The advantages in this system relate to the maintenance of tension of the liner and the avoidance of having to position a large disc like structure over the top and within a cylindrical receptacle or container.
