Abstract
Abstract An arrangement to increase (or decrease) the temperature in sea or lake water within a limited area. The arrangement is constituted by a basin (F, P1-P4, V1-V3, N1-N3 etc.) which is constructed and located in the sea water which temperature is desired increased. The basin shall primarily make the water circulation difficult between the basin and the outer sea so that a temperature difference is achieved, but it is not fully tight to allow a certain circulation. In one model (FIG. 1) the water circulation is uncontrolled with firm and statically arranged elements (YP1-YP3, HP1-HP7, E1-E10). In another model (FIG. 5) the elements of the basin (J1-E10). In another model (FIG. 5) the elements of the basin (J1-J3) are operated with regard to a temperature aimed at. Several more models (FIG. 8, FIG. 9, FIG. 12 etc.) are described.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
135 words
An arrangement to increase or decrease the temperature in sea water within a limited water area, said arrangement being constituted by a basin-like construction built in the sea, the water temperature of which should be increased or decreased, said construction comprising a bottom part rigidly anchored in the bottom of the sea, column-like parts rigidly attached to and supported by said bottom part, said column-like parts to hold partitioning means in place in between, said column-like parts projecting in a vertical direction towards the water surface from said bottom part to form rigid corners of the basin-like construction, said partitioning means structure to hold wall elements which geographically separate the water inside and outside said basin-like construction, said wall elements being water-pervious to provide an exchange of the water inside and outside said basin-like construction.
Claim 2
Dependent Claim
135 words
An arrangement to increase or decrease the temperature in sea water within a limited water area, said arrangement being constituted by a basin-like construction built in the sea, the water temperature of which should be increased or decreased, said construction comprising a bottom part rigidly anchored in the bottom of the sea, column-like parts rigidly attached to and supported by said bottom part, said column-like parts to hold partitioning means in place in between, said column-like parts projecting in a vertical direction towards the water surface from said bottom part to form rigid corners of the basin-like construction, said partitioning means structure to hold wall elements which geographically separate the water inside and outside said basin-like construction, said wall elements being water-pervious to provide an exchange of the water inside and outside said basin-like construction.
Claim 3
Dependent Claim
91 words
An arrangement as claimed in claim 1 wherein said column-like parts are constituted by longitudinal profile elements having a certain cross-section, secured in a vertical direction to said bottom part, said wall elements consisting of porous floatable elements and each of said profile elements having a uniform profile shape throughout its whole length and at least partly enclosing a wall element in order to enable a free movement of the wall element in the longitudinal direction in dependence on the water level and a very limited movement in the lateral direction.
Claim 4
Dependent Claim
42 words
An arrangement as claimed in claim 2 wherein a number of said wall elements are arranged in each section defined by the cross-section of two adjacent profile elements, an expansion element being provided fastened to adjacent wall elements in the same section.
Claim 5
Dependent Claim
63 words
An arrangement as claimed in claim 1, wherein said column-like parts are arranged in a polygon, said wall means each consisting of a frame having a number of directed plates, each of said plates being rotateably secured in said frame to form a jalousie-like arrangement in order to controllably allow the water flow between the inside and the outside of the basin-like construction.
Claim 6
Dependent Claim
88 words
An arrangement as claimed in claim 1, wherein said bottom part is constituted by a scale rigidly anchored to the sea bottom, said column-like parts being integrated with said socle and forming a polygon, said wall means being constituted by a soft water-resistant sheet material provided with openings and by shaft means on the top and the bottom of said column-like parts in order to controllably roll said sheet material up and down and thus adjusting the level of said openings in relation to the sea water layers.
Claim 7
Dependent Claim
69 words
An arrangement as claimed in claim 1, wherein said bottom part is constituted by a rigidly anchored socle on the sea bottom, said column-like parts being integrated with said bottom part and forming a polygon, said wall means being constituted by a net fastened to said column-like parts, said net including controllably operable gate-modules for controlling the water flow between the inside and the outside of the basin-like construction.
Claim 8
Dependent Claim
65 words
An arrangement as claimed in claim 6, wherein at least one of said module gates has been substituted by a propeller means connected to the axis of a motor for controlling the water flow between the inside and the outside of the basin-like constructin, a centrifugal governor being connected to valve means for controlling said water flow independent of the direction of the water flow.
Claim 9
Dependent Claim
23 words
An arrangement as claimed in claim 1, wherein said bottom part is constituted by a foundation provided with a number of evacuation openings.
Claim 10
Dependent Claim
13 words
An arrangement as claimed in claim 8, wherein said evacuation openings are active.
Claim 11
Dependent Claim
13 words
An arrangement as claimed in claim 8, wherein said evacuation openings are passive.
Claim 12
Dependent Claim
73 words
An arrangement as claimed in claim 1, wherein temperature sensing means are provided on the outside of said partitioning means for sensing the temperature of the water outside the basin-like construction, computer means responsive to the sensed water temperature to deliver a control quantity, and control means for said wall elements to control the exchange of water between the outside and the inside of the basin-like construction in dependence of said control quantity.
