US4498294A – Buoyancy Prime Mover With Pressure Control Means – Google Patents

SEMEG. Delirium en el postoperatorio During operation, the pump 68 and cooling unit 46 (with the valve 74) can be used to control the gas pressure within the open space 36 by varying (1) the gas flow from the open space 36 to the compressor 52 and (2) the temperature of the cooling unit 46. This will determine the pressure of the gas within the open space 36 and will directly affect the buoyant forces acting on each bucket 30. The displacement of the pump 68 can be controlled by conventional means including a variable speed electric motor. During the descent, the buckets are filled with liquid or are collapsed into a flat configuration and the buckets need not be driven downward against buoyant forces. 4, an extending member 90 of the liquid entry valve is adapted to engage a cam 92 positioned about each upper sprocket 20. The cam 92 is arcuate-shaped and has the same outer radius as the radius of the upper sprockets 20. The engagement of the extending member 90 with the cam 92 opens the valve 80 and allows liquid to flow into the bucket 30. A similar cam could be positioned about each lower sprocket 24 to engage the displacement of the liquid from the bucket as the bucket is filled with gas.

1 and 2) which engage the upper and lower sprockets 20 and 24. The flat belts 116 can be cogged to provide a positive traction as the sprockets rotate. To avoid this problem, each bucket can be provided with a partition 38 that separates the interior of the bucket into two sections–a primary chamber 40 and a reserve chamber 42 (see FIG. The operation of the present invention and the recirculation of the gas will now be described with reference first to FIG. Dolor muscular zona riñones . 4, an additional embodiment of the present invention is shown having buckets 30 with liquid entry valves 80 in the innermost wall of each bucket relative to the chain 26 and displacement ports 82 along the bottom edge 84 of the bucket. Both the top and bottom shafts should be positioned below the surface of the liquid. According to Archimedes’ principle, this will create a force of buoyance (FB) in the bucket equal to the weight of the displaced liquid.

Note that when these panels are descending, the total unbalanced force that is developed must be great enough to drive the buoyant panels downward against the buoyant force. The buckets are moved downwardly by the action of gravity upon the water which creates an unbalanced force and rotates a series of sprockets and a connected shaft.

As the gas expands, more liquid is displaced so that the buoyant force acting on each bucket constantly increases during the rise. At approximately 120° of rotation, the lowest bucket is totally devoid of gas so that power is being generated inefficiently during the cycle. Therefore, the chains 26 form a continuous loop having two parallel, vertical columns of the buckets evenly spaced on the chain to reduce vibration and to increase power input.

As a result, the bucket speed tends to increase, and the effect is more pronounced as the length of continuous loop of buckets is increased. The Millard apparatus includes buckets at the upper end of the loop which are completely exposed to the atmosphere. The present apparatus and the apparatus of my copending application are directed to this problem of efficient power generation. This reduces horizontal bucket motion and therefore increases the efficiency of the apparatus.

A ridge 88 along the top of the bucket 30 provides a surface for the bucket to join with the bottom edge 84 of a preceding bucket and form an ascending and descending column of joined or nested buckets which move through the liquid with minimum turbulence. The bracing cord is a strong, flexible, non-stretching member that is connected along a bucket side to the top rear surface and the bottom front side of the bucket to keep opposite bucket sides parallel to each other and perpendicular to the bottom edge 84 of each bucket. Therefore, when the gas filled buckets round the upper sprockets 20, liquid is admitted into the buckets at two points–over the bottom edge 84 of the bucket and through the opening 88 in the side of the bucket.

5) is a spring-loaded device that covers an opening 88 in the side of each bucket 30. The valve 88 acts to increase the speed of the liquid-gas displacement as the buckets revolve about the upper sprockets 20. As indicated in FIG. The liquid entry valve 80 (see FIG. Para el dolor muscular por ejercicio . Liquid entry valves are not necessary in the collapsible buckets. 3) and the remainder of the gas passes between the side wall of the bucket A and the inner wall of the enclosure 10 to pass into a bucket B positioned above bucket A. As will be described, the buckets can be rigid or collapsible. The energy used to drive or push the buoyant panels downward decreases the energy produced on the rising side. 5, the valve 80 comprises a plate 94 which covers the opening 88 in the side of the bucket. The bucket pitch also determines the clearance between buckets upon rotation about the sprockets 20 and 24. The nesting configuration restricts the movement of each bucket about the joint connecting the chain and bucket to minimize the horizontal motion of the chain.

The ridge also restricts the twisting effect of the buckets relative to the chain 26 which can be produced as the buckets pass through the liquid. A gas is introduced at a given depth into a body of liquid held within an enclosed container. When the collapsible bucket closes, the bracing cord folds into the bucket. 7. As illustrated, the walls of the collapsible bucket fold inwardly to form a compact structure. The collapsible bucket should be formed of a material that will fold easily and wear well; for example, a polyethylene resin or a reinforced rubber composition. The use of collapsible buckets has several advantages over the use of rigid buckets.

One column moves upwardly as the buoyant forces act on the buckets. The following references constitute the closest prior art of which applicant is aware. Accordingly, there are many devices described in the prior art for the generation of power by harnessing a rising gas in a fluid. The prior art, however, does not disclose the embodiments of the present invention. Bearing housings 18 contain bearings (not shown) to encircle the shaft and permit relatively friction-free shaft rotation. The compressor 52 converts the relatively cool, low pressure gas to a heated, high pressure gas which is forced into a condensing unit 56 comprising a housing 58 containing a coiled tube 60 with associated cooling plates 62. Pomada para dolor muscular . The housing 58 also contains a liquid, within which the tube 60 and plate 62 are immersed, to absorb the heat transferred from the heated gas to the condensing unit 56. The liquid is the same fluid contained in the enclosure 10. Specifically, the liquid is circulated between the enclosure 10 and the condensing unit 56 by conduits 64 and 66–conduit 64 directs the liquid from the enclosure 10 to the condensing unit 56 and conduit 66 returns the heated liquid from the condensing unit to the enclosure.

Gas enters the liquid and rises into the lowest bucket of the wheel to displace a volume of liquid. Fundamental to the present invention is the natural expansion of the gas as it rises in the liquid (due to a continually decreasing liquid pressure). Burwell notes that the top sprocket is above the liquid level. A locking collar 22 fixes the position of each sprocket on the respective shaft. The sprockets 20 and 24 must firmly engage the chain 26 to maintain a sufficient chain tension so that the chain does not slip from the sprocket teeth 28 (see FIG. FIG. 2 is a sectional view taken along the line 2–2 of FIG. The buckets can move in a vertical direction upwards or downwards through the liquid. This gas is captured, retained and fully utilized during its rise in the liquid to make better use of the energy input than does the Fogarty device.

As the gas expands, more liquid is displaced so that the FB acting on each bucket constantly increases during the rise. The liquid condenses on the coils 44 and the associated plates 54 of the cooling unit 46 and falls by gravity into the body of liquid. The constant gas supply is generated in a closed system whereby the gas is released into an open space over the liquid in the enclosed container to be condensed, pressurized and recirculated for reuse in the system.

This would produce additional friction and turbulence as the buckets pass through the liquid. The upper sprockets can be adapted to rotate freely about the top shaft 14, but that would not enable power to be transferred from the top shaft. The buckets of the present invention, however, must be at least partially immersed in the liquid for efficient power production. The ability to displace the gas and fluid rapidly is of fundamental importance to efficient power production. If a container is placed in the path of the rising gas, the gas will enter the container and displace an equal volume of liquid from the container. That limitation of the Baumgartner invention is significant because frictional drives are very inefficient and limited in their ability to transmit torque. A spring 102 is positioned around each shaft 100 and is held in place by a stop nut 104 secured in a fixed position on the threaded end 106 of the shaft 100. A seal or gasket 108 can be placed between the plate 94 and the inside surface of the bucket wall.
