A horizontal beam above a door or a window is commonly refered to as a "lintel."
Intake fan and exhaust fan or an open door and window are all creating ventilation. In other words putting fresh air into a room and removing bad air is ventilating a room. Hope this helps.
On Plugdoors, When unbolted by Cabin Crew the door drops inwards... They door is made small in height but gates folding inwards on the top and bottom of the door, Then the door is made smaller with width by being twisted to a 25* angle and pushed out through the hole then swung like a normal house or bedroom door till it is fully opened and laying on the aircrafts skin!
They use Hydraulic fluid that is pressurized by the opening of the door to control gears speed to allow for a steady closing of the door . Most have valve adjustments that increase or decrease the pressure to allow the door to speed up or slow down.
First, if the key is only slightly jammed, wiggling and jiggling it might work it loose. However, I am assuming that if you are asking this question, the key must be good and jammed. If that is the case, the only way I know of is the following; however, it involves destroying the key and therefore, you should be prepared to obtain a new key from a locksmith. First, hopefully the door is unlocked, or open. If it is closed and locked, you will have to try the following. Remove the hinge pins from the door by tapping them out with a hammer and a centre punch, nail, or other pointed metal instrument. Once the hinge pins are out, try pulling the door away from the frame from the hinge side. You should then be able to remove the door from the frame even if the deadbolt is locked. (Note: This assumes you are on the side of the door where the hinge pins are visible. If not, you will have to access the other side of the door via a window into the room. Good luck!) Once you have gotten the door open by these means (if necessary), remove the doorknob, then the escutcheon plates (face plates with the keyhole in them). This will expose the hole drilled in the door for the keyhole, and the lock case itself. Now take a pair of locking pliers ("Vise Grips") and grab onto the shank of the key as close to the lock case as possible. Work the pliers back and forth until the key breaks off. Hopefully, the break will occur as close to the lock case as possible. Now, remove the screws from the edge of the door which hold the lock case in place. You should now be able to slide the lock case out of the door. Unscrew the cover from the lock assembly and extract the broken piece of key, being careful not to disturb any of the tumblers (levers), springs, etc. Good Luck!
"Mild steel" is low-carbon steel. It is the cheapest, most common and and most versatile form of steel, and is more malleable than high-carbon steels. It would be used in door handles because it is cheap and easily shaped.
The horizontal beam above a door or window is sometimes called a lintel. This part of the door or window is a portion of the frame in most cases.
a lintel, or a lintel beam.
A bressummer beam carries loads from above but has no window or door below it. Therefore its allowable deflection (long term or short loads) can be greater. A lintel on the other hand has a window or door below it and requires less deflection to ensure that the operation of the window/door is not compromised.
