Abstract: An apparatus reduces the insertion-required force in a coil inserting apparatus. A coil and an insulating material piece are automatically inserted into the groove of a stator core by the operation of a coil pusher. A current flows from a piezo-electric element accommodated within the coil pusher, when insertion resistance applied upon the coil pusher has increased, through the relay solenoid valve to drive a hydraulic cylinder thereby raising the coil wrapping jig. When the insertion pressure has suddenly increased, the current stops to keep fundamentally the coil wrapping jig synchronous to the motion of the coil pusher.

Abstract: In automatic firearms having a caliber in the range of about 20 to 40 mm, so-called "jammed shell casings" are occasionally encountered due to the high cadences during the extraction and ejection of the empty cartridge casings, so that the returning breech mechanism tends to lose the cartridge, and the ejector plunger no longer fully impacts against the casing to be ejected. In order to avoid this drawback a recess arranged in the breech head concentrically to the firing pin is provided along its periphery opposite an extractor claw with at least one projection to assist in the centering and retention of the cartridge casing and which can be adapted to the respective type of breech mechanism. The projection is formed by cutting or non-cutting working. Preferably, two or more such projections are formed which then, together with the extractor claw, form a type of "three-point support" for the cartridge casing during the extraction.
