In addition, the hairspring would lengthen, decreasing its spring constant.

The hairspring kept the escapement going and the clock thus produced was small enough to keep in a pocket.

The balance would, at least theoretically, actually decrease in size with heating to compensate for the lengthening of the hairspring.

This has allowed for silicon components to be substituted for some parts which are usually made of steel, such as the hairspring.

The escapement still gets deregulated at the moment of the shock, but the hairspring does not get as easily deformed from shocks as before.

In this a stiff mainspring gradually uncoiled, supplying a steady force that kept a much thinner hairspring oscillating steadily.

Regulating Systems 3 The hairspring should be pinned in a grooved plate with a stud having a rounded collar and cap.

Edward Scales from Hairspring Watercress (www.hairspring.org.uk) has several acres of it growing on a natural spring source.

His movement had been smooth and catlike; his face was expressionless, but his muscular frame stood poised on a hairspring.

Ulysse Nardin in cooperation with GFD developed the first hairspring for the balance wheel in polycrystalline diamond.

This oscillation is not exactly a parallel to the balance wheel and hairspring of a clockwork watch, but the fact is that both use oscillations to keep track of passing time.

I stopped the truck and got out and stood on the running board and kicked the snow off the bonnet and if they'd wanted to squeeze the hairspring at this precise moment they could have blown my head off.

Mechanical movements also use a balance wheel together with the balance spring (also known as a hairspring) to control motion of the gear system of the watch in a manner analogous to the pendulum of a pendulum clock.

Pedometers that gauge movement with a flimsy mechanism called a hairspring and that cost less than $15 (like the ones you get with fast-food kids' meals, for example) often wear out within six months and may give you wrong information, according to a recent Real Simple article.

Most notably is the hairspring, which functions as the timing regulator for the escapement and is thus the part most sensitive to any exterior effects, such as magnetism, shocks, temperature, as well as inner effects such as pinning positions (inner collet), terminal curve, and heavy points on the balance wheel.
