For Mozilla and Opera 9, there are also undocumented events known as DOMContentLoaded and DOMFrameContentLoaded which fire when the DOM content is loaded. These are different from "load" as they fire before the loading of related files (e.g., images). However, DOMContentLoaded has been added to the HTML 5 specification. [13]
Ready to fire position. Bolt is locked to barrel, both are fully forward. Recoil of firing forces bolt and barrel fully to the rear, compressing the return springs for both. Bolt is held to rear, while barrel unlocks and returns to battery under spring force. Fired round is ejected. Bolt returns under spring force, loads new round.
Bolt: The part of a repeating, breech-loading firearm that blocks the rear opening of the barrel chamber while the propellant burns, and moves back and forward to facilitate loading/unloading of cartridges from the magazine. The extractor and firing pin are often integral parts of the bolt. Bore rope: A tool used to clean the barrel of a gun.
Remington-Rider Magazine Pistol has a manually-actuated rolling block action to pull a cartridge from a tubular magazine set below the barrel and simultaneously cock the firearm. The block was rolled back into battery, loading the cartridge into the chamber, by spring pressure while the hammer remained in the cocked position.
Such manuals contain various evolutions, such as the twelve or so steps needed to load, ready and fire, and steps for fixing bayonets, forming line (for firing), column (for bayonet charges) or square (for repelling cavalry). A second example is the manual used for training of US Union troops in 1861. [2]
The examination of the cartridge relies on the unique tool marks left by the various parts of the weapon including the firing pin and the ejector in semi and fully automatic firearms. These markings can be compared and matched to known exemplars fired from the same weapon using the same parts.
The actual logic is contained in event-handler routines. These routines handle the events to which the main program will respond. For example, a single left-button mouse-click on a command button in a GUI program may trigger a routine that will open another window, save data to a database or exit the application.
A double set trigger achieves the same result, but uses two triggers: one sets the trigger and the other fires the weapon. Double set triggers can be further classified into two different phases. [6] A double set, single phase trigger can only be operated by first pulling the set trigger, and then pulling the firing trigger.
