Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
325 words
A system for cyclically varying the heights of liquid columns confined in tubes, said system comprising an enclosure, a tank in said enclosure, a liquid in said tank, said liquid having a free surface exposed to air at a given static pressure, two banks of tubes partly immersed in said liquid, said tube banks being located at opposite ends of said tank, two identical manifolds, one above each of said tube banks and open to the interior of said tubes, a source of static pressure lower than that exerted above the free surface of said liquid and located midway between said manifolds, a four ported control valve located close to said source of lower static pressure, two of said ports being respectively connected to said two manifolds, a third port being open to the air space above said tank and the forth port being connected to the source of lower static pressure, four suitably shaped compartments in said control valve, four internal passages between said compartments, a suitable control blade in said control valve, said blade being capable of moving between two extreme positions each corresponding to a different pairing between the four ports, suitable motor means to switch said blade between two dwell positions coinciding with said extreme positions, said switching occurring cyclically and said blade establishing an air flow path between a manifold and the air space above the tank when said blade is in the dwell position of the first half of a cycle, and between same manifold and the source of lower static pressure when said blade is in the dwell position of the second half of the cycle, the other manifold being placed in simultaneously opposite conditions, said cyclic switching of the blade causing simultaneously opposite motions of said liquid in said two banks of tubes and generating waves in said tank and, motor speed control means for obtaining a cyclic operation adapted to the end use of said system.
Claim 2
Independent Claim
325 words
A system for cyclically varying the heights of liquid columns confined in tubes, said system comprising an enclosure, a tank in said enclosure, a liquid in said tank, said liquid having a free surface exposed to air at a given static pressure, two banks of tubes partly immersed in said liquid, said tube banks being located at opposite ends of said tank, two identical manifolds, one above each of said tube banks and open to the interior of said tubes, a source of static pressure lower than that exerted above the free surface of said liquid and located midway between said manifolds, a four ported control valve located close to said source of lower static pressure, two of said ports being respectively connected to said two manifolds, a third port being open to the air space above said tank and the forth port being connected to the source of lower static pressure, four suitably shaped compartments in said control valve, four internal passages between said compartments, a suitable control blade in said control valve, said blade being capable of moving between two extreme positions each corresponding to a different pairing between the four ports, suitable motor means to switch said blade between two dwell positions coinciding with said extreme positions, said switching occurring cyclically and said blade establishing an air flow path between a manifold and the air space above the tank when said blade is in the dwell position of the first half of a cycle, and between same manifold and the source of lower static pressure when said blade is in the dwell position of the second half of the cycle, the other manifold being placed in simultaneously opposite conditions, said cyclic switching of the blade causing simultaneously opposite motions of said liquid in said two banks of tubes and generating waves in said tank and, motor speed control means for obtaining a cyclic operation adapted to the end use of said system.
Claim 3
Dependent Claim
26 words
A system as defined in claim 1 wherein the blade drive motor speed and the magnitude of the lower static pressure could be altered at will.
Claim 4
Dependent Claim
81 words
A system as defined in claim 1 wherein the source of lower static pressure comprises converging-diverging passages between solid walls, a primary fluid flowing through said passages and creating static pressure variations along said passages, wall apertures when the passages have their minimum cross sections, said apertures being subjected to a lower static pressure than that exerted in the air space above the tank when the flow of primary fluid is sufficiently fast and, a duct communicating with all said apertures.
Claim 5
Dependent Claim
14 words
A system as defined in claim 3 wherein the pRimary fluid is atmospheric air.
Claim 6
Dependent Claim
195 words
A system as defined in claim 4 and adapted for heating purposes, wherein the converging-diverging passages are created with several aerodynamically shaped blades positioned at regular intervals above each other and secured to an upright hollow column located in the atmosphere and provided with a wind vane in a perpendicular plane to the blades'' length, said column being vertically and rotatably mounted at the top of a tall structure erected above the tank containing enclosure and provided with servicing means, wherein the duct communicating with all said apertures consists of said hollow column, wherein the control valve is located at the base of the hollow column and one of its ports communicates with said column''s interior via a rotary joint, wherein the tank contains many baffles and several ducts immersed in the liquid, said ducts confining the flow of a heat transport fluid which is suitably circulated in said enclosure, wherein the blade drive motor speed is chosen to produce cyclic motions of the liquid in said tubes, motions which lead to a maximum of friction between said liquid and the solid walls and, wherein the tank containing enclosure and the tank are thermally insulated.
Claim 7
Dependent Claim
181 words
A system as defined in claim 4 and adapted for heating purposes, wherein the converging-diverging passages are created with several horizontal hollow disks having symmetrical convex surfaces, said disks being positioned at regular intervals above each other and secured to a central hollow column located in the atmosphere and mounted vertically at the top of a tall structure erected above the tank containing enclosure and provided with servicing means, wherein the duct communicating with all said apertures consists of said hollow column, wherein the control valve is located at the base of the hollow column and one of its ports communicates directly with said column''s interior, wherein the tank contains many baffles and several ducts immersed in the liquid, said ducts confining the flow of a heat transport fluid which is suitably circulated in said enclosure, wherein the blade drive motor speed is chosen to produce cyclic motions of the liquid in said tubes, motions which lead to a maximum of friction between said liquid and the solid walls and, wherein the tank containing enclosure and the tank are thermally insulated.
Claim 8
Dependent Claim
220 words
A system as defined in claim 5, wherein the tank containing enclosure has a living space with a thermally insulated floor separating it from the tank, wherein the tall structure contains a short hollow column secured to the roof of said enclosure, a tall hollow column hinged to said short column and provided with a top platform for supporting the column blades assembly, two pipes descending within said hollow columns and containing flexible portions at the column hinge section, each said pipe originating from a control valve port, said pipes continuing along the ceiling of the heated enclosure until each of them joins its respective manifold located along opposite ceiling-wall intersections, wherein the heat transport fluid is outside air admitted into the ducts immersed in the tank, delivered heated and in controlled quantity to the living space and eventually exhausted through the base of said short column, the bore of both said columns, openings at the upper end of said tall column and through a properly oriented side opening in a cap secured to and rotating with the column blades assembly and, wherein the servicing means consist of an auxiliary column erected above said enclosure and equipped with a winch whose cable guided by a pulley located at the top of said auxiliary column, is attached to said tall column.
