Bascule Bridge
A bascule bridge (also referred to as a drawbridge or a lifting bridge) is a moveable bridge with a counterweight that continuously balances a span, or leaf, throughout its upward swing to provide clearance for boat traffic. It may be single- or double-leafed. The name comes from the French term for balance scale, which employs the same principle. Bascule bridges are the most common type of movable span because they open quickly and require relatively little energy to operate, while providing the possibility for unlimited vertical clearance for marine traffic. History Bascule bridges have been in use since ancient times, but until the adoption of steam power in the 1850s, very long, heavy spans could not be moved quickly enough for practical application. Types There are three types of bascule bridge and the counterweights to the span may be located above or below the bridge deck. The fixed-trunnion (sometimes a "Chicago" bascule) rotates around a large axle that raises the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bascule (horse)
Bascule is the natural round arc a horse's body takes as it goes over a jump. The horse should rise up through its back, stretching its neck forward and down, when it reaches the peak of his jump. Ideally, the withers are the highest point over the fence. This is often described as the horse taking the shape of a dolphin jumping out of the water. Bascule can also refer more generally to the raising of the withers while the horse is in motion. Importance of bascule A horse with bascule is one with a "round" jump, while a horse with poor bascule may jump "flat" with his head in the air and his spine relatively straight. A hollowed back over the fence tends to prevent the animal from lifting his forearms very high, thus preventing the necessary tucking motion of his front legs to jump clear. Most naturally talented jumpers have good bascule. However, there are several very athletic horses that can jump great heights with considerably poor bascule due to sheer power. Some bascule ...

Bascule Light
A bascule light or tipping lantern (Danish:''vippefyr'') was a type of small navigational aid popular in Denmark in the 18th century and before. It consisted of a basket in which wood or coal was set; this was then burned. The basket was affixed to a bascule that allowed it to be manipulated as required. (The bascule – from the French for "seesaw" – refers to the counterbalancing of the lever, which facilitates raising and lowering the basket; when one end is lowered the other is raised.) The ''vippefyr'' system was generally viewed as ineffective, as it produced little light and was usually unreliable. Background In 1560 Frederick II of Denmark ordered the erection of beacons at Skagen, Anholt and Kullen Lighthouse to mark the main route through Danish waters from the North Sea to the Baltic. The current vippefyr at Skagen is a reproduction of the original, which dates back to 1626, preceding Frederick's decree. The design dates to 1624 and Jens Pedersen Groves. The lightho ...

Cecal Bascule
Cecal bascule is a cause of large bowel obstruction where there is folding of the cecum anteriorly over the ascending colon. It is one of two types of cecal volvulus, the other being axial ileocolic. It is caused by rotational torsion of the cecum or ascending colon along its own axis. In cecal bascule, the base of the cecum folds anteriorly over the ascending colon, creating a flap-valve, obstructing emptying of the cecum. The condition can be complicated by necrosis or organ perforation before the diagnosis is made, particularly if the ileocecal valve is competent, preventing retrograde decompression of the cecum into the ileum The ileum () is the final section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear and the terms posterior intestine or distal intestine ma ....{{Cite journal , last1 = Pousada , first1 = L. , title = Cecal bascule: An overlooked diagnosis in t ...

Teeterboard
The teeterboard or Korean plank is an acrobatic apparatus that resembles a playground seesaw. The strongest teeterboards are made of oak (usually 9 feet in length). The board is divided in the middle by a fulcrum made of welded steel. At each end of the board is a square padded area, where a performer stands on an incline before being catapulted into the air. The well-trained flyer performs various aerial somersaults, landing on padded mats, a human pyramid, a specialized landing chair, stilts, or even a Russian bar. The teeterboard is operated by a team of flyers, catchers, spotters and pushers. Some members of the team perform more than one acrobatic role. In the early 1960s the finest teeterboard acts, trained in the Eastern Bloc countries, performed with Ringling Brothers and Barnum & Bailey Circus. Korean-style teeterboard called Neolttwigi is a form of teeterboard where two performers jump vertically in place, landing back on the apparatus instead of dismounting onto a land ...
