Three Rings
In Tolkien's mythology, the Three Rings are magical artefacts forged by the Elves of Eregion. After the One Ring, they are the most powerful of the twenty Rings of Power. The Three Rings were made by Celebrimbor after Sauron, in the guise of ''Annatar'', had left Eregion. These were free of Sauron's influence, as he did not have a hand in their making. However, they were still forged by Celebrimbor with the arts taught to him by Sauron and thus were still bound to the One Ring. Upon perceiving Sauron's intent, the Elves hid the Three from him. They were taken from Middle-earth to the blessed realm of Valinor at the end of the Third Age, after the destruction of the One Ring. Commentators have observed that the Three Rings enabled the Elves to halt the passage of time within their realms, especially in Lothlórien where Galadriel wielded Nenya. Others have noted that their power was benevolent, in sharp contrast to the One Ring, and could be used to protect and to heal; and tha ...

3-ring Release System
The 3-ring release system is a parachute component that is widely used by sport skydivers and military freefall parachutists to attach the two risers of a main parachute to the harness that bears the load under the parachute. Invented in its original large ring form by Bill Booth, and subsequently scaled down for thinner Type 17 webbing risers the three-ring system allows a skydiver to quickly cut-away a malfunctioning main parachute with a single motion. Skydivers usually need to do this quickly during emergencies in which they need to deploy a reserve parachute. The three-ring system is simple, inexpensive, reliable, and requires fewer operations than earlier parachute release systems while reducing the physical force needed. The large bottom ring is securely attached to the skydiver's harness, the middle ring is securely attached to the end of the parachute riser, and the small ring is securely attached to the parachute riser above the middle ring. The middle ring is passed thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Borromean Rings
In mathematics, the Borromean rings are three simple closed curves in three-dimensional space that are topologically linked and cannot be separated from each other, but that break apart into two unknotted and unlinked loops when any one of the three is cut or removed. Most commonly, these rings are drawn as three circles in the plane, in the pattern of a Venn diagram, alternatingly crossing over and under each other at the points where they cross. Other triples of curves are said to form the Borromean rings as long as they are topologically equivalent to the curves depicted in this drawing. The Borromean rings are named after the Italian House of Borromeo, who used the circular form of these rings as a coat of arms, but designs based on the Borromean rings have been used in many cultures, including by the Norsemen and in Japan. They have been used in Christian symbolism as a sign of the Trinity, and in modern commerce as the logo of Ballantine beer, giving them the alternative ...

Heterocyclic Compounds, 3-ring
A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). Heterocyclic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of these heterocycles. Examples of heterocyclic compounds include all of the nucleic acids, the majority of drugs, most biomass (cellulose and related materials), and many natural and synthetic dyes. More than half of known compounds are heterocycles. 59% of US FDA-approved drugs contain nitrogen heterocycles. Classification The study of heterocyclic chemistry focuses especially on unsaturated derivatives, and the preponderance of work and applications involves unstrained 5- and 6-membered rings. Included are pyridine, thiophene, pyrrole, and furan. Another large class of heterocycles refers to those fused to benzene rings. For example, the fused benzene derivatives of pyridine, thiophene, pyrrole, and furan are quin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tricyclic
Tricyclics are chemical compounds that contain three interconnected rings of atoms. Many compounds have a tricyclic structure, but in pharmacology, the term has traditionally been reserved to describe heterocyclic drugs. Among these are antidepressants, antipsychotics, anticonvulsants, and antihistamines (as antiallergens, anti-motion sickness drugs, antipruritics, and hypnotics/sedatives) of the dibenzazepine, dibenzocycloheptene, dibenzothiazepine, dibenzothiepin, phenothiazine, and thioxanthene chemical classes, and others. History * Promethazine and other first generation antihistamines with a tricyclic structure were discovered in the 1940s. * Chlorpromazine, derived from promethazine originally as a sedative, was found to have neuroleptic properties in the early 1950s, and was the first typical antipsychotic. * Imipramine, originally investigated as an antipsychotic, was discovered in the early 1950s, and was the first tricyclic antidepressant. * Carbamazepine was disco ...

Three-ring Binder
Ring binders (loose leaf binders, looseleaf binders, or sometimes called files in Britain) are large folders that contain file folders or hole punched papers. These binders come in various sizes and can accommodate an array of paper sizes. These are held in the binder by circular or D-shaped retainers, onto which the contents are threaded. The rings themselves come in a variety of sizes, including , though other sizes are also available. The rings are usually spring-loaded, but can also be secured by lever arch mechanisms or other securing systems. The binders themselves are typically made from plastic with metal rings. Early designs were patented during the early 1890s to the early 1900s. History American Henry Tillinghast Sisson invented the three ring binder, receivinpatent no. 23506on April 5, 1859. German Friedrich Soennecken invented ring binders in 1886 in Bonn. He also registered a patent on November 14, 1886, for his ''Papierlocher für Sammelmappen'' ("paper hole ...

Three-ring Circus
A circus is a company of performers who put on diverse entertainment shows that may include clowns, acrobats, trained animals, trapeze acts, musicians, dancers, hoopers, tightrope walkers, jugglers, magicians, ventriloquists, and unicyclists as well as other object manipulation and stunt-oriented artists. The term ''circus'' also describes the performance which has followed various formats through its 250-year modern history. Although not the inventor of the medium, Philip Astley is credited as the father of the modern circus. In 1768, Astley, a skilled equestrian, began performing exhibitions of trick horse riding in an open field called Ha'Penny Hatch on the south side of the Thames River, England. In 1770, he hired acrobats, tightrope walkers, jugglers and a clown to fill in the pauses between the equestrian demonstrations and thus chanced on the format which was later named a "circus". Performances developed significantly over the next fifty years, with large-scale th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
