48、ctuate the igniter and open the main fuel safety shutoff valve. d. When the flame-sensing device does not sense the main flame within 15 seconds after the main fuel valve opens, the device shall lock the burner out to prevent automatic recycling. When this occurs, a manual restart sh...
Fortifications must be designed with large factors of safety. However, maximum prob- able penetrations and effects must be kept in mind, so that works may be strong enough to resist the fire that can be brought against them without an unnecessary expenditure of labor and material. 36. ...

or may be booby-trapped with anti-lift devices. The second mine neutralization technique, demolition, is achieved with high explosives like C-4 or TNT. Unfortunately, this approach has significant hindrance such as safety, cost, effective destruction, storage, transportation, and training. Furthermor...

An additional safety mechanism is provided to prevent final arming of the fuse assembly 32 until a launch setback is sensed as the projectile 10 leaves the rifle muzzle. The arming interlock setback pin 90 is biased against the slider pin 88 by the setback spring 92. The slider pin 88 biase...
reduce overall processing costs since the components of the iron-based alloy system are relatively easier and less expensive to manufacture compared with cobalt-based materials. This also eliminates some safety concerns associated with the fabrication of cemented tungsten carbide components containing cobalt...
