Abstract: A process to brake a part of a mechanism includes applying a first torque, applying a second torque and braking the part. The mechanism is urged to alternatingly swivel along a path in a first direction from a first position to a second position by a spring connected to the part. The first torque is applied to the part with the spring to swivel the part in a first direction from the first position to the second position. The first torque is defined by a strain-release force of the spring in a tensed position. The second torque is applied to the part with the spring in a second direction opposite the first direction. The second torque is less than the first torque and is defined by the strain-release force of the spring. The part is braked along at least a part of the path. As a result, the motion of the part can be slowed simply and inexpensively.

Abstract: A functioning mechanism for a small caliber automatic weapon includes a translatable and rotatable sear, and a rotatable hammer. The sear includes a hooking element adapted to contact a bearing surface of the hammer to render the hammer immobile. Rotating movement of the sear is controlled by the hammer in such a way as to obtain clean contact between the hooking element and the bearing surface.
