The mechanism is named after the effect of solar radiation passing through glass and warming a greenhouse, but the way it retains heat is fundamentally different as a greenhouse works by reducing airflow, isolating the warm air inside the structure so that heat is not lost by convection.

Pearls are formed inside the shell of certain mollusks as a defense mechanism against a potentially threatening irritant such as a parasite inside its shell, or an attack from outside, injuring the mantle tissue.

For example, if the user dials " 6 " on a North American phone, electrical contacts wired through the cam mechanism inside the phone will open and close six times as the dial returns to home position, thus sending six pulses to the central office.

For example, railroad wheels have little traction, and friction brakes without an anti-skid mechanism often lead to skids, which increases maintenance costs and leads to a " thump thump " feeling for riders inside.

The mechanism for this effect is due to ribavarin's buildup inside erythrocytes.

Card readers tended to jam when a lace card was inserted, as the resulting card had too little structural strength to avoid buckling inside the mechanism.

The application of tacks is generally discouraged by piano technicians as the tacks can drop off the hammers and lodge in the strings or jam the mechanism, or the fact that placing tacks inside felt hammers renders the felt unvoicable and, therefore, ruins the hammers.

) The pendulum swings back and forth in tempo, while a mechanism inside the metronome produce a clicking sound with each oscillation.

Typically, the bolt consists of a tube of metal inside of which the firing mechanism is housed, and which has at the front or rear of the tube several metal knobs, or " lugs ", which serve to lock the bolt in place.

Due to their lack of speed and their inability to bite or sting, millipedes ' primary defense mechanism is to curl into a tight coil — protecting their delicate legs inside an armored body exterior.

This acid would erode the inside of the gun barrel and the lock mechanism.

Pair production is also the hypothesized mechanism behind the pair instability supernova type of stellar explosion, where pair production suddenly lowers the pressure inside a supergiant star, leading to a partial implosion, and then explosive thermonuclear burning.

The presence of giants tends to increase eccentricities and inclinations ( see Kozai mechanism ) of planetesimals and embryos in the terrestrial planet region ( inside 4 AU in the Solar System ).

The available text says that inside the vessel was a central column that could move along eight tracks ; this is thought to refer to a pendulum, though it is not known exactly how this was linked to a mechanism that would open only one dragon's mouth.

If the temperature inside the furnace exceeds a maximum threshold, a safety mechanism with a thermostat will shut the furnace down.

This may have been known to the ancient Greeks: in the Antikythera mechanism, the saros cycle is represented in a dial arranged as a 4-turn spiral, which also has quadrant divisors on its inside.

The inner tube is encased inside the outer tube and held in place by a locking mechanism.

on the presence of malaria parasites inside lymphatics suggest a mechanism for the recrudescence and chronicity of malaria infection.

This process is supported by a tiny valve mechanism located inside the expander and it will continue until its size is slightly larger than the other breast.

These attachments are stowed inside the handle of the knife through a pivot point mechanism.

There is usually a trigger mechanism built into the base of the spigot, with a long firing pin running up the length of the spigot activating a primer inside the projectile and firing the propellant charge.

This is purely a defense mechanism, to trap a potentially threatening irritant such as a parasite inside its shell, or an attack from outside, injuring the mantle tissue.

One interesting thing is that Buchner hypothesized that yeast cells secrete proteins into their environment in order to ferment sugars, instead of the fermentation occurring inside the yeast cells, which is the actual mechanism.

The Anti-Snap lines act as sacrificial points, meaning that if force is applied to either end of the cylinder it will break away only to the Anti-Snap line, leaving the mechanism inside the door intact-allowing the correct key to still operate the lock.

The original diagram of Su Song's book Xin Yi Xiang Fa Yao ( published 1092 ) showing the Water clock | clepsydra tank, waterwheel, escapement mechanism, chain drive, striking clock jacks, and armillary sphere of his clock tower.

* 1094 – The Chinese mechanical engineer and astronomer Su Song incorporates an escapement mechanism and the world's first known chain drive to operate the armillary sphere, the astronomical clock, and the striking clock jacks of his clock tower in Kaifeng.

The clock tower featured large astronomical instruments of the armillary sphere and celestial globe, both driven by an early intermittently working escapement mechanism ( roughly two centuries before the discrete verge escapement of true mechanical clocks appeared in medieval clockworks ).

The water-powered mechanism of Su Song | Su Song's astronomical clock tower, featuring a clepsydra tank, waterwheel, escapement mechanism, and chain drive to power an armillary sphere and 113 striking clock jacks to sound the hours and to display informative plaques

The same mechanism would be used by Su Song ( 1020 – 1101 ) in 1088 to power his astronomical clock tower, as well as a chain drive.

In Song China, an astronomical clock tower was designed by Su Song and erected at Kaifeng in 1088, featuring a liquid escapement mechanism.

It is believed that sometime in the late 13th century the verge escapement mechanism was applied to tower clocks, creating the first mechanical clock.

Like the earlier water-power employed by Zhang Heng and the later escapement mechanism in the astronomical clock tower engineered and erected by Su Song ( 1020 – 1101 ), Yi Xing's celestial globe employed water-power in order for it to rotate and function properly.

The civic tower ( 1555 ) is 55m high and it has a clock of the 1773 with very interesting counterbalance mechanism.

* All four clock faces on the clock tower being replaced, and the clock mechanism repaired

In December of 1777 Maximilian Joseph rode in his carriage through Munich ; on the ride, as he passed one of the tower clocks, the mechanism broke, and the clock struck 77 times.

The lens is rotated by an elaborate clockwork mechanism that is powered by weights running down the center of the tower which can be wound by a crank at the top.

Su Song was the engineer of a water-driven astronomical clock tower in medieval Kaifeng, which employed the use of an early escapement mechanism.

The escapement mechanism of Su's clock tower had previously been invented by Buddhist monk Yi Xing and government official Liang Lingzan in 725 AD to operate a water-powered armillary sphere, although Su's armillary sphere was the first to be provided with a mechanical clock drive.

Su Song was also strongly influenced by the earlier armillary sphere created by Zhang Sixun ( 976 AD ), who also employed the escapement mechanism and used liquid mercury instead of water in the waterwheel of his astronomical clock tower ( since liquid mercury would not freeze during winter and would not corrode and rust metal components over time ).

A replica now stands 20 metres away from the old clock tower, with the original clock mechanism installed in the new tower.

Both the tower and the clock date from the last decade of the 15th century, though the mechanism of the clock has subsequently been much altered.

The tower was built during 1496 and 1497 and the mechanism of the clock was then built into it under the supervision of the Ranieri.

Once he has reached the top of the tower, Pogo needs to enter a door to trigger the tower's destruction mechanism.

Red track of Big Shot ( ride ) atop Stratosphere Las VegasThe mechanism consists of a central tower around which rows of seats are placed with the riders facing outward away from the tower.
