At the start of the firing sequence, the bolt is held to the rear. Pulling the trigger permits the bolt to move forward, stripping a cartridge from the magazine, chambering, firing, extracting and ejecting it. A closed bolt gun starts the firing squence with a round already chambered, and the bolt closed on the cartridge. The M3 Greasegun was an open bolt, the Thompson SMG a closed bolt.
The MP5, without question. It's a closed bolt design, vs. the Type 100's open bolt design, with matching rates of fire. On single shot mode, the Type 100 would probably have better range, though.
Hugo Schmeisser headed the design team from Haenel which developed the MP43/Sturmgewehr44. However, it was not solely the work of Schmeisser, or even the Haenel company, alone - the original design was an open bolt, striker fired design, and it was actually the competing Walther design from which the closed bolt method of operation was taken.
The bolt is in the closed (forward) position when the weapon fires, as opposed to an open bolt, in which the bolt is in the open (rearward) position when the weapon fires. Rifles are typically closed bolt weapons, whereas belt fed machine guns usually fire from the open bolt (one exception to this is the belt fed machine guns based on the HK91/93 platform, such as the HK11 and HK21).
an open bolt gun is simply a gun that fires from an open bolt, the only time the bolt is closed is during the firing and when the firing is stopped the bolt remains open. many open bolt guns have an integral firing pin machined directly on the bolt examples of open bolt guns: uzi mac Thompson 1928
Which would be better in lighting a house a closed or an open circuit ?\
Open ear hearing aids have better sound quality based on reviews. I would personally only use the open ear design.
eyes open :)
A closed interior design which sepertates each worker in a office

It depends on the phototransistor's design. Most are normally open until you shine light on them.
You can only be absolutely certain if the bolt is open and no cartridge is seen in the chamber. If it has a magazine the magazine must also be empty to avoid the gun automatically loading when the bolt is closed.
