Firing mechanism

This favorable situation results from the fact that no excessive restriction is placed on the weight, volume, or geometry of the firing mechanism. Consequently, the primers used in these... 

Check the rifle to be sure the safety and firing mechanism operate normally. 

All hydrocarbon fire mechanisms and estimates will be affected by to some extent of flame stability features such as varying fuel composition as lighter constituents are consumed, available ambient oxygen supplies, ventilation patterns, and wind effects. Studies into these effects have generally not progressed to the level where precise estimations can be made without scale model tests or on site measurements. 

In areas notsubjectto freezing, fire, mechanical damage, or blast damage, aboveground piping is acceptable. Mains should be kept outside of areas... 

Time Blasting Fuse Igniter M2 (Weatherproof) (Fig 20) consists of a tube that holds at one end the firing mechanism, while at the other end (base) is placed a percussion primer and a pronged fuse retainer. When the release pin... 

Following are examples of "firing devices" 1) Delay Type Firing Device Ml (Demolition) (Fig 22) consists of a two-part cylindrical case, joined near the center-by a coupling. The half of the case which contains firing mechanism is brass, while the other half contg glass am-... 

The electric detonator is ordinarily used to actuate a booster or booster lead (usually Tetryl). At the time of publication of NOLR 1111, which was 1952, electric detonators were used in Naval mine and torpedo firing mechanisms and to a limited extent in Army fuzes (See also Section 2, Part C, History of Development of Detonators, etc")... 

Fuze, Mine. A fuze designed to initiate a train of fire in a land mine. For initiation of underwater (sea) mine a device known as "Firing Mechanism, Underwater Mine" It is a device contg combustible or explosive components, which can be actuated by an acoustic signal, impact, hydrostatic pressure, and/or magnetic influence (Ref 40a, pp 71... 

Fuze, Rocket. A fuze for initiating a rocket warhead. Some rockets, such as the 12.75-inch Rocket are initiated by firing mechanisms, such as Mkl5ModO... 

Fuze, BD M72 is a delay-action provided for use on 57-mm APC (armor-piercing-capped) projectile M86. It is based on the same principle as the M66A1 and M66, and has a similar firing mechanism as well as the same tracer (C), primer (B) and detonator... 

Fire, 1000-lb, Mk79 Mod 1, with fuzes and igniters located on the sides of the body) 2-56, Fig 2-40 (Bomb, Smoke, PWP or WB, 100-lb, AN-M47A4 with nose fuzes AN-159 or AN-M126A1) 2-58, Fig 2-42 (Bomb, Gas, Nonpersistent, GB, 10-lb, M125A1 with firing mechanism and nose fuze) Note ... 

M) Parachute Recovery Test. This test developed at PicArsn has been used for the recovery of fired mechanical time fuzes for investigation. The method consists... 

The firing mechanism (instead of hydrostatic pistol) was housed in a well at one end of the case. It was probably used on suicide boats (qv) Type 3 120 Kilogram Army Depth Charge (Experimental) was 24V inches long and 15% inches in diameter, filled with 200 lbs of HE (no data). It was fired by a pull igniter instead... 

Influence Sea Mines, were of various shapes, but usually they were cylindrical, like a bomb in appearance. They did not require contact with a ship in order to fire, and hence could be laid on the bottom many feet below the ship. Any physical change which took place in the water around the mine to the ship s passage over it could be utilized to actuate the firing mechanism. However, the most common types were magnetic and acoustic. Any mine without horns or antenna was almost certainly either an influence mine, or else a Controlled Mine, connected by an electric cable to the shore and fired by sending a current thru that cable (p 35)... 

Type 96 Mine was ellipsoid in shape and contd 120 lbs of Type 88 or Type 97 Expl. It was reported to be attached to antisubmarine nets. The firing mechanism of mine was of the tension type which detonated the mine when an enemy s submarine fouled a panel of the net (pp 44—45, Fig 16)... 

JM Mine was moored, pear-shaped, contact mine which had no horns. The jolt received by the pendulum firing mechanism, when a ship struck the mine, closed an electrical contact and fired the detonator. - The mine was filled with ca 110 lbs of a HE ( ) (pp 44-45, Fig 18) Pomegranate Mine was a Vickers antenna mine purchased before WWII. It was spherical, 41 inches in diam, with six chemical horns on the upper hemisphere and two addnl ones welded to the lower hemisphere. An upper antenna and float and/or lower antenna were secured to the mine. No data for HE filler (pp 44 45, Fig 19) Type 3 Mine was the first Japanese attempt to use influence mines, copied from German S Mine. Their cylindrical A1 cases were either 7 or 11 feet long and 21 inches in diam. No data for HE used and the description of the mine given in Ref 1, p 46 is hard to understand Mark 2 Mod 1 Explosive Hook was actually a device for mine sweeping rather than a mine. 

MF+KC103+Sb2Sa, (serving as a propint) and a small lead bullet. The ignition of mixt is caused by the compression of the rim of the case against the breech of the barrel when it.is struck fcy the hammer of the firing mechanism. The pressure of gas developed in the cartridge is sufficient to propel the bullet a few yards... 

Packing, Grenades should be packed separately from bouchens and firing mechanism, each in a separate wooden box or in a separate compartment of the same box. The exception is in the case of grenades loaded with EC Blank Fite Powder which can be packed with firing mechaoism assembled... 

Renovation and Salvage. Similar to regulations outlined under "Trench Mortar Ammunition", with the exception that bouchons and firing mechanisms are not ten ova ted or salvaged unless directed by the proper authority Destruction. For offensive hand grenades and and rifle grenades, not more than 40 grenades shall be packed in close contact with each other in a box and the ensemble placed in a pit, about 4 ft deep, free from stones or other... 

Drawing and cross-sectional view of a typical one-kilogram, Electron homb. Note blunt nose and awkward streamlining. With the exception of the sheet iron tail and firing mechanism, the bomb Is constructed entirely of incendiary materials... 

The term cannon does not include mount, but only barrel(tube), breech mechanism and firing mechanism... 

While efforts were made to improve the firing mechanism of the gun, development work was also being carried out to improve accuracy and reliability. A bullet fired from a smooth bored...
