  Annular structure meant for pieces of real jewelry and cheap jewelry, particularly for rings - Patent 5483808
The annular structure according to claim 1, characterized in that the external and internal annular elements are provided with cooperating locking means for a removable locking of said elements in a superposed position of the external annular element on the internal annular element and/or in an exposed position of this latter element.
The annular extension is meant for being kept beside the external annular element in the position in which this element is superposed on the internal annular element, and this annular extension may have any suitable size and shape which may be substantially the same as, or complementary to the external annular element.
To expose the internal annular element 2, the internal annular element 2 of a smaller diameter is axially shifted laterally outwardly by the external annular element 1 and extends therefrom by at least a part of its axial extent.

 Annular Cutters Offer Holemaking Benefits
The annular cutting concept differs from other drilling tools in that it is a hollow tool and provides multiple cutting edges rather than the typical two edges found on the majority of conventional drills.
Annular cutters, in part because of the number of teeth and partly because they do not rely on the geometry for running straight, are particularly advantageous for such unique capabilities as oblique entry, entry in concave and convex surfaces.
Other applications where annular cutters excel are in making radius notches at the edge of steel plates (drilling half of a hole), or to radius the end of tubing for miter joints, drilling overlapping holes, and “inverse” drilling, meaning the slug is not removed, but left as a post on the part.

 Annular - LoveToKnow 1911
An annulated cross is one with the points ending in an "annulet" (an heraldic ring, supposed to be taken from a coat of mail), while the annulet in architecture is a small fillet round a column, which encircles the lower part of the Doric capital immediately above the neck or trachelium.
The word "annulus" (for "ring") is itself used technically in geometry, astronomy, andc., and the adjective "annular" corresponds.
An annular eclipse is an eclipse of the sun in which the visible part of the latter completely encircles the dark body of the moon; for this to happen, the centres of the sun and moon, and the point on the earth where the observer is situated, must be collinear.

 Differential Diagnosis of Annular Lesions - July 15, 2001 - American Family Physician
Granuloma annulare is characterized by nonscaly, annular plaques with indurated borders, typically on the extremities.
Granuloma annulare is an idiopathic, self-limited cutaneous condition that is common in adults and children.
It is believed that erythema annulare centrifugum represents a cutaneous manifestation of a hypersensitivity reaction to a myriad of underlying conditions, including: infection by dermatophytes, bacteria and viruses; malignancy; and immunologic disorders.

 APSA :: Resources for Parents : Annular Pancrease   (Site not responding. Last check: 2007-10-31)
An annular pancreas (arrows) surrounding the duodenum and cavity a blockage.
Annular pancreas is a cause of severe blockage of the first part of the small intestine in the fetus and may produce increased amniotic fluid in the mother.
When annular pancreas is found, an intestinal bypass should be done around the annular blockage without disturbing the annular pancreas itself because of the risk of injuring the pancreatic tube within it, which could result in a chronic leak of pancreas enzymes and fluid.

 Annular Pore
NTPase activity in the nuclear envelope seems to be associated with the annular part of nuclear pore complexes (permanent component) and with RNP particles translocated through nuclear pores or attached to the surface of nuclei (transitional component).
The annular and rod-like images were also observed when various steps in the ghost isolation procedure, such as the use of detergents, 0.5 M MgCl2 and polylysine attachment of the ghosts to electron-microscope grids, were circumvented.
The annular and rod-like images are connected into linear and polygonal arrays by strands (15-30 nm in width) that are sensitive to DNase I and DNase II but resistant to nuclease S1.

 Annular hurricane - Wikipedia, the free encyclopedia
An annular hurricane is a tropical cyclone in the Atlantic or Eastern Pacific oceans that features a large, symmetric eye surrounded by a thick ring of intense convection.
Most annular hurricanes have peak intensities of greater than 85 knots (98 mph, 157 km/h) and more than 85% of their theoretical maximum potential intensity.
In terms of the Dvorak technique, annular hurricanes weaken very slowly after their peak (on average, less than 0.5 T after one day from their peak intensities).

 Annular Solar Eclipse of 2003 May 31
An annular eclipse (Latin "annulus") is one where the Moon is too small to cover the Sun completely, and leaves a proportion of the Sun showing.
Annular eclipses can pass unnoticed because the remaining part of the Sun is so bright the environment is not noticeably dimmed.
Annular eclipses occur with a slightly higher frequency than total solar eclipses, and are quite rare in small islands such as Britain.

 The Annular Port Air Gun
The Annular Port Air Gun is a new design for a marine air gun that provides significant improvements in both the operating efficiency and acoustic output of marine seismic source arrays.
The principal feature of the Annular Port Air Gun design is an annulus containing the air chamber and shuttle valve surrounding a hollow passage through which air supply hoses and electrical control cables are routed.
The improvement in peak output is attributable to the increased surface area of the toroidal-shaped bubble compared to the spherically shaped bubble generated by a conventional 4-port air gun.

 Eclipse Expedition to Costa Rica 2001   (Site not responding. Last check: 2007-10-31)
Losing the ring phase of an annular eclipse is not nearly as bad as missing a totality, actually: Especially with a ring as thick as the one just now eluding us, it´s just a specially shaped partiality.
With annularity missed, it was time to head for La Casona, but there was actually no need to rush: The construction site was just a few kilometers away from the dormitory, and it would take the Sun another half hour to finally outrun the lower edge of the cloud bank.
On June 10, 2002 an annular eclipse will be visible (weather permitting, of course) precisely at sunset from the West Coast of the Mexican mainland - and, it being the Saros successor of the famous near-total U.S. eclipse of 1984, the ring will be extremely narrow.

 Center for Advanced Nuclear Energy Systems (CANES) | Research | High Performance Fuel Design for Next Generation PWRs   (Site not responding. Last check: 2007-10-31)
The annular fertile-free Pu loaded and highly uprated core appears to be feasible, but power uprates in these cores is restricted to less than 50% because of relatively high power peaking and a potential for slightly positive MTC at BOC.
The conclusions is that fabrication of annular fuel elements can be done by commercial fabrication techniques, at reasonable costs, and should not be an inhibiting factor in the commercial introduction of annular fuel to improve the performance of existing light water reactors.
For the currently operating Generation II power plants, annular fuel provides a means to significantly upgrade the power output (50% or more) using the same nuclear island with new reactor internals, steam generators and circulation pumps, and a new incremental balance of plant to handle the increased power production.

 Making a condenser annular ring for a phase contrast objective
Sourcing the correct annular ring plates for the condenser is tricky if not impossible for older microscopes.
Although each annular ring has to be precisely matched to a given objective for phase contrast to work, it is possible to make a missing ring to a sufficient accuracy; especially if it's for a medium to high power objective i.e.
The annular ring plate made using a slide-ringing table is shown below, alongside the maker's plates for the other objectives.

 Annular Solar Eclipse
The sun's chromosphere and several prominences are seen on the left hand side of the solar disk.
Partial solar eclipses take place when the orbits of the sun and moon intersect but only part of the sun is covered by the moon.
Annular eclipses occur when the moon and sun align exactly, but the moon does not completely cover the full disk of the sun because its apparent size is not as large as the apparent size of the sun.
