 balance - HighBeam Encyclopedia   (Site not responding. Last check: 2007-11-03)
A spring balance consists of a coiled spring fixed to a support at one end, with a hook at the other to which the body to be weighed is applied.
For example, the analytical balance, a type of equal-arm balance, is used for delicate weighing in quantitative chemical analysis and in preparing pharmaceutical prescriptions; it must be kept in a glass case, since its accuracy is easily affected by dust and moisture.
A so-called torsion balance, which depends on the twisting of a wire or thread, is employed for weighing, but the term is commonly used to indicate a device for measuring minute electrical and magnetic forces.

 Block and tackle sash counter balance - Patent 6467128
Connected to the top shoe is a spring, and a block and tackle pulley assembly is connected between the bottom end of the spring and the bottom shoe, wherein a cord from the pulley assembly extends outward from the bottom shoe for connection to the window sash.
The balance assembly of claim 11, wherein the bottom shoe further includes teeth along at least a portion of an exposed edge thereof, wherein said teeth increase the frictional force between the bottom shoe and the window frame when the exposed edge is adjacent the window frame and affixed thereto.
The balance assembly; of claim 1, wherein the relative length of the channel, the pulley assembly and the spring are such that the spring is maintained in slight extension and produces a compressive force applied to the channel of less than 1.0 lbs.

Spring balances were also invaluable for plank-frame houses, where the absence of wall framing made weight pockets impossible, and in solid brick walls, where spring balances alleviated the need to build openings any wider than necessary for the window proper.
If you are replacing an existing spring balance, remove the screws securing the balance, gently cut the paint seal around the faceplate with a sharp razor knife, then pry out the balance using a screwdriver or awl.
If you are installing a spring balance in place of a rope pulley, remove the old pulley and enlarge the pocket to accept the new balance using a sharp wood chisel.

 The Balance Wheel of a Watch - TimeZone
The balance and spring are known as a "rotary oscillating system." Although we impart meaning to a watch--it "shows" the time or even the moon--as a mechanism it is simply a way to regulate the unwinding of a spring.
Having swung to a fully clockwise position, the balance wheel has "wound" the balance spring, and it is the force of the spring unwinding that reverses the direction of and propels the balance in the opposite direction, to the fully counter-clockwise position.
Thus, when steel springs were all that were available, it was seen that a rise in temperature caused an increase in the thickness of the balance spring, an increase in the height and length of the spring, and a reduction in the "modulus" (elasticity) of the spring.

This mechanism was made of a bimetallic strip acting on the length of the balance spring to automatically shorten or lengthen it as a function of temperature change.
The expansion of the balance and the lengthening of the balance spring also produce a small loss which is compensated for by increasing the thickness and height of the balance spring.
The result was a semicircular bimetallic balance in two parts whose outer rim was made of brass and inner rim made of steel, both equipped with a screw to permit any necessary modification.

 Spring scale - Wikipedia, the free encyclopedia
A spring scale (or spring balance) is a weighing scale often used to measure force, such as the force of gravity, exerted on a mass or the force of a person's grip or the force exerted by a towing vehicle.
Many spring scales are marked right on their face "Not Legal for Trade" or words of similar import.
Some spring scales can be calibrated for the accurate measurement of mass in the location in which they are used.
