Timer
A timer is a specialized type of clock. A timer can be used to control the sequence of an event or process. Timers can be mechanical, electromechanical, digital, or even software, since most computers have clocks.
Mechanical Timers
Early mechanical timers used typical clockwork mechanisms, such as a escapement and spring to regulate their speed. Inaccurate, cheap mechanisms use a flat beater that spins against air resistance. Mechanical egg-timers are usually of this type.
More accurate mechanisms resemble small alarm clocks. The chief advantage of these is that they require no battery, and can be stored for long periods of time. The most widely-known application is to control explosives.
Electromechanical timers
Electromechanical timers have two common types. A thermal type has a metal finger made of two metals with different rates of thermal expansion (steel and bronze are common). An electric current flows through this finger, and heats it. One side expands less than the other, and an electrical contact on the end of the finger moves away from an electrical switch contact, or makes a contact (both types exist). The most common use of this type is now in the "flasher" units that flash turn signals in automobiles, or sometimes in christmas lights.
Another type of electromechanical timer (a cam timer) uses a small synchronous AC motor turning a cam against a comb of switch contacts. The AC motor is turned at an accurate rate by the alternating current, which power companies carefully regulate. Gears slow this motor down to the desired rate, and turn the cam. The most common application of this timer now is in washers, driers and dish-washers. This type of timer often has a friction clutch between the gear train and the cam, so that the cam can be turned to reset the time.
Electromechanical timers survive in these applications because mechanical switch contacts are still less expensive than the semiconductor devices needed
One Timer
A one timer (or one-time) is an ice hockey shot that occurs when a player meets a teammate's pass with an immediate slapshot, without any attempt to control the puck on his stick. An effective one timer requires precise timing on the part of both players involved, especially the shooter. This play often results in a good chance at a goal. The effectiveness of the one timer comes in the speed of the puck after it is slapshot, and also in the sudden change of the puck's direction.

Dear phizzics; There is no such thing as "time" in and of itself, Heisenberg got it murphy's-law-wrong : momentum(M)is not a determinant of the quantum area(h), it is a RESULT of balanced dW=dPv or delta matter wavelength equals delta particle velocity; and t=dKE=m=(W not=to P), and not-t=PE=M=(W=P). Consider the oxymoron "delta momentum" : delta means rate of change, momentum means no change of state(newton's first law), so how, with HONESTY, do you say : rate of change of...no change of state? Then consider "rest mass", another oxymoron. If its at REST then nothing is changing, but "mass" means that you have MEASURED some object(weight/accel/decel)which means a CHANGE of state. So, you see that both Heisenberg and Einstein got it wrong with their oxymorons...and De Broglie got something RIGHT : matter waves, the true source of "time". There is a simple graph that shows how it all works. W=P

software timers ?
imagine some application scheduler (high priority thread) which keeps list of running (started) timers and calls hooks supplied by the application when timer expires http://cvs.sourceforge.net/viewcvs.py/larytet/emLIB/AOS/aosTimer.h?rev=1.1&view=markup
Sunbeam (Car)
Sunbeam was a marque registered by John Marston Co. Ltd of Wolverhampton, England in 1888. The company first made bicycles, then motorcycles and cars from the late 18th century to ca. 1936, and applied the marque to all three forms of transportation. A Sunbeam was the first British car to win a Grand Prix race, and set a number of land speed records. Sunbeam was combined with the French Talbot-Darracq to form Sunbeam-Talbot-Darracq in 1920, and was purchased by the Rootes Group in 1935. Rootes did not use the Sunbeam name until the 1935 launch of the new Sunbeam-Talbot marque. These cars were rebadged Hillman and Humber models with unique body work. The Talbot name was dropped in 1954 for the Sunbeam Alpine sports car and later Rapier and Alpine-derived Tiger. It was sometimes used in place of its sister Hillman marque in Europe.
The last Sunbeam was the 1976 Rapier, when Chrysler, who had purchased Rootes, disbanded the marque. A subcompact hatchback, the Chrysler Sunbeam, resurrected the name from 1978 to the early 1980s.
