The Gatling gun's operation centered on a cyclic multi-barrel design which facilitated cooling and synchronized the firing / reloading sequence.

* An externally actuated machine gun uses an external power source, such as an electric motor or even a hand crank to move its mechanism through the firing sequence.

The firing sequence ( known as ripple firing ) required firing the first retro, followed by the second retro five seconds later ( while the first was still firing ).

The ignition sequence was symmetrical, with each cylinder firing 120 ° after the previous cylinder resulting in smooth power delivery.

This diagram shows the operating sequence of a Medusa propulsion spacecraft ( 1 ) Starting at moment of bomb / pulse unit firing, ( 2 ) As the bomb's explosion pulse reaches the parachute canopy, ( 3 ) Pushes the canopy, accelerating it away from the bomb explosion as the spacecraft plays out the main tether with the winch, braking as it extends, starting to accelerate the spacecraft, ( 4 ) And finally winches the tether back in.

The entire reloading sequence was a more complex procedure than later designs, however, as the firing pin had to be independently primed and activated, and the lever was only used to move the bolt.

At the same time, a large test stand capable of measuring more than eight million pounds of thrust was converted from a former Saturn F-1 large engine test stand to the first vertical large solid rocket booster test stand in the nation, capable of holding the booster in an upright position during the entire firing sequence and measuring its massive thrust.

Ablation mechanism firing sequence.

The ignition firing sequence begins with the points ( or contact breaker ) closed.

It was the first field gun to include a hydro-pneumatic recoil mechanism, which kept the gun's trail and wheels perfectly still during the firing sequence.

Captain Sainte-Claire Deville also designed important additional features, such as a device for piercing the fuzes of shrapnel shells automatically during the firing sequence ( an " automatic fuze-setter "), thus selecting the desired bursting distance.

# Load each chamber in sequence ( original ), setting the hammer in the safety notch when finished ; or ( safe and prudent method ) load one chamber, skip the next, load the remaining four chambers, close the loading gate, draw the hammer to full cock and lower fully, making sure that the firing pin is over the empty chamber.

Upon detection, the SDF-1 began an automatic firing sequence that the crew could not stop that destroyed two Zentradi scout ships.

There were other purposes: the close-order drill was a particular cadence count for the complex sequence of loading and firing a musket.

The firing sequence was staggered so all the bombs would land at about the same time.

Confidence in the design was regained in August, however, when the same stage, S-IVB-201, performed flawlessly on a full-duration firing of 452 seconds, which was the first engine test sequence to be controlled entirely by computers.

With the assistance of other characters revealed by audio chapters, the fictional protagonists break into a secure military installation and manage to deactivate a Forerunner device which is implied to begin the firing sequence of the Halo installations.

Though the Master Chief and Arbiter form a tenuous alliance with the Flood to stop the activation of all the Halo rings, as soon as the firing sequence is stopped Gravemind turns on the humans.

* Animation of a M1911 firing sequence

Controlled by a computer, the synchronizer can dictate the timing of each frame of the CCD camera's sequence in conjunction with the firing of the laser to within 1 ns precision.

When the Arbiter tries to stop the firing, Tartarus forces Keyes to insert the Index, initiating Halo's firing sequence.

One must first detect a fleeting mobile or moving target, decide that it is worthy of destruction, select the missile to be fired against the target, compute ballistics for the flight, and prepare the missile for firing.

While clay is still pressed in mold, press three equally spaced holes 1/4'' '' deep, using pencil eraser, in bottom of clay to allow for proper drying and firing.

As a finale is appended a close-up of one of the band taking aim and firing his revolver straight at the audience.

No Union soldiers were observed to have ever gotten behind Johnston during the fatal charge, while it is known that many Confederates were firing at the Union lines while Johnston charged well in advance of his soldiers.

* 1941 – Corporal Josef Jakobs is executed by firing squad at the Tower of London at 7: 12 am, making him the last person to be executed at the Tower for treason.

Turret stabilization is an important capability because it enables firing on the move and prevents crew fatigue.

For example a target acquisition element can send a message with target details which is automatically routed through the tactical and technical fire control elements to deliver firing data to the gun's laying system and the gun automatically laid.

The process to produce firing data this is sometimes called technical fire control.

A possible example of actual use of two guns firing at the same time is " Dual wield ", practiced by Russian special forces.

While this does bear some similarity with the classic posture of cowboys firing their twin revolvers from the hip, in games this posture is almost never reflected, with almost all game characters firing twin guns at shoulder level, straight-armed.

Counter-Strike is a notable exception, in that the player models are seen externally to fire akimbo Berettas from the hip, but appear to be firing from shoulder level from the first-person perspective.

When alcohol consumption is stopped too abruptly, the person's nervous system suffers from uncontrolled synapse firing.

A bomber is a military aircraft designed to attack ground and sea targets, by dropping bombs on them, firing torpedoes at them, or – in recent years – by launching cruise missiles at them.

Jim is given the task of exploding the bombs, which he does by firing pistol shots into them.

In this capacity they establish policies and make decisions on issues such as whether there is dividend and how much it is, stock options distributed to employees, and the hiring / firing and compensation of upper management.

While firing a higher quantity of smaller bullets makes it easier to hit a target ( and is therefore good for beginner marksmen ), it offers very little to more advanced marksmen.

The term cannon is also used for autocannon, a modern repeating weapon firing explosive projectiles.

The earliest known depiction of a gun is a sculpture from a cave in Sichuan, dating to the 12th century that portrays a figure carrying a vase-shaped bombard, firing flames and a ball.

The same basic engine block can be used with different crankshafts, however, to alter the firing order ; for instance, the 90 ° V6 engine configuration, in older days sometimes derived by using six cylinders of a V8 engine with what is basically a shortened version of the V8 crankshaft, produces an engine with an inherent pulsation in the power flow due to the " missing " two cylinders.

In double trigger designs, it is often possible to pull both triggers at once, firing both barrels simultaneously, though this is generally not recommended as it doubles the recoil, battering both shooter and shotgun.

* 1896 – Filipino patriot and reform advocate José Rizal is executed by a Spanish firing squad in Manila, Philippines.

Davros now has a mechanical hand which is capable of firing electricity.
