The bitting code is used in conjunction with a key's Depth and Spacing Number to completely determine all relevant information regarding the key's geometry. [1] Each number in the bitting code corresponds to a cut on the key blade. For example, a bitting code of 11111 with Depth and Spacing Number 46 specifies a Kwikset key with five shallow cuts.

[ 3 ] Due to its importance during World war II footage, Arriflex 35 cameras were later used in the Nuremberg Trials .The original Arriflex 35 had three Arri standard mounts on a rotating turret.
