| 203 | System And Method For Hydraulic Displacement | US12225146 | 2007-02-23 | US20090162145A1 | 2009-06-25 | Terry Fogarty |
| A system and method for hydraulic displacement is described which can provide an improved method for raising or lowering a fluid level. The system and method has direct application to inland waterway transport and in particular to canal locks where canal boats traverse inclines through a series of locks. In addition, the invention can provide the access to a marina, which may be raised up above sea level or behind a sea wall defence. The method enables the formation of an improved hydraulic displacement lock capable of a greater vertical displacement with greatly reduced flow of fluid through the lock. The hydraulic displacement lock comprises an enclosed central channel, having sequential fluid storage tanks connected to the central channel. When the central channel is closed at its lower end, opening and closing connecting channels to the sequential storage tanks allows fluid to flow under the force of gravity into or out of the central channel, thereby raising or lowering the level of fluid. | ||||||
| 204 | Watercraft lock | US11740833 | 2007-04-26 | US07520231B2 | 2009-04-21 | Richard B. Bishop |
| A watercraft transport lock includes a walled structure that can be filled and emptied of water received from two separate bodies of water for the purpose of transporting a boat or other watercraft between the two bodies of water. The system prevents the water of one body from mixing with the water of the other body. This is accomplished by removing the water of the first body of water from within the structure prior to filling the structure with the water from the other body. A boat support may be used to support the boat during the emptying and filling processes. | ||||||
| 205 | CANAL LOCK SYSTEM | US11838407 | 2007-08-14 | US20080038062A1 | 2008-02-14 | Manuel G. Allonca |
| A canal lock system for recirculating water between a reservoir and canal lock that uses air pressure to change the water level in the canal lock. The canal lock system comprises at least one canal lock, at least one reservoir for holding recirculated water connected to the bottom of the at least one canal lock, and at least one air pump connected to the at least one reservoir for pressurizing the at least one reservoir with air to force the water into the at least one lock to thereby change a first water level in the at least one canal lock to a higher second water level, wherein the at least one reservoir maintains a constant volume and wherein the at least one reservoir is depressurized to thereby change the second water level to a lower third water level. | ||||||

| 207 | Boat lift apparatus | US09371321 | 1999-08-10 | US06174106B1 | 2001-01-16 | Richard B. Bishop; Charles L. Bishop |
| The present invention relates to a stationary boat lift comprised of a housing in which a boat is able to enter and exit with little difficulty. The boat lift allows a boat to bypass various barriers in a efficient and safe manner by vertically lifting the boat out of one body of water, translating the boat horizontally over a desired barrier, and then vertically lowering the boat into a second body of water. | ||||||
| 208 | Method and equipment for maintaining ice-free locks | US866066 | 1992-04-09 | US5232309A | 1993-08-03 | Esko Pontynen |
| The method and equipment for keeping locks free of ice utilizes the natural energy resources of the waterway itself. Gravity is utilized to conduct warm water from the depths of the upper waterway via a pipe (1) into the lock where it is distributed by a network of pipes punctuated with holes (3) along the lock floor and around the lock gates. Cooled water is discharged through outlets (6) located in the lower lock gates or lock wall just below the level of the upper waterway. Warm water can effectively be brought to the surface by the use of compressed air conducted to the lock floor either through a special network of pipes or through the existing system (3). The piping may be laid on or under the lock floor. Heatloss can be reduced by insulating the sides of the lock and by fitting the lock with a cover the underside of which is coated with a heat-reflecting material. All the necessary equipment for maintaining an ice-free lock can be installed in both already existing and new locks, thus facilitating inland navigation all year round. | ||||||
| 209 | Pumping system for gates | US253197 | 1988-10-04 | US4877537A | 1989-10-31 | Ichiji Kobayashi; Motohide Sakata |
| A pumping system for gates wherein a sluice body liftably received in the guide grooves formed in the side walls of a water channel mounts a plurality of pumps in parallel with each other, the suction ports and the discharge ports of the pumps being located in the upstream and downstream sides, and a debris collecting device is provided in the water channel upstream the pumps. The suction ports of the pumps are opened towards the bottom of the water channel at a given height, and the debris collecting device is so constructed that it can be liftable over the level of the water channel. At the time of a natural drainage, the sluice body and the debris collection device are lifted to allow free flow of the water through the water channel, while at the time of a forced drainage the sluice body and the debris collecting device are lowered so that debris, etc. flowing in the upstream side of the water channel are first collected by the debris collecting device, and the water is then pumped from the upstream to the downstream sides by the suction thereof through the pit. | ||||||
| 210 | Installation for accelerating navigation of a water ramp and method relating thereto | US69183 | 1979-08-23 | US4275973A | 1981-06-30 | Jean Aubert |
| The installation enables an internal waterway to pass through a changing level by means of a water ramp connecting through a channel two water reaches respectively situated upstream and downstream and including basins for the storage of boats awaiting their turn before entering the water ramp. The upstream reach is provided with a tilting gate for the retention of the water, while a pusher provided with a transverse mask retaining a water-wedge on which the boat to be moved floats is movable along the channel to ensure the transfer of this boat from the downstream reach to the upstream reach and vice versa. The retaining gate for the upstream reach is located at a certain distance beyond the upstream end of the water ramp and a second retractable gate is arranged substantially at the end of the water ramp, these two gates bounding between themselves an intermediate horizontal reach, separating the upstream end of the water ramp and the upstream basin. | ||||||
