Abstract: An electrochemical energy storage cell comprising a cell winding received in a casing, wherein the casing is closed at least on one end face by a cover, wherein the cover has a fixing portion for fixing the cover on the casing and a pole portion for contacting a conductor of the cell winding, wherein the fixing portion and the pole portion are connected to one another via a compensating element, wherein the compensating element is formed to be elastic and electrically insulating.

Abstract: An operating system for an individual firearm, such as a rifle, comprises a carriage (14) sliding axially in the compartment of the body of the firearm, an obturator (10) associable to the barrel (2), an elastic element (16), compressible between the carriage (14) and the obturator (10). In the configuration of firearm ready to fire with the bullet in the barrel, the obturator (10) has a free compression stroke (D) for the compression of the elastic element (16) and the barrel (2) has a free firing stroke (C) in relation to the abutment (32) of the operating compartment (8).

Abstract: A thermal barrier (1) for firearms (A) comprising a body (2), optionally substantially cylindrical, made of a ceramic material. The body (2) is shaped and configured for being placed between a respective barrel (C) of a firearm (A) and at least one structure (S) of the firearm (A). The body (2) of the thermal barrier (1) has a first portion (3) suitable for remaining facing the barrel (C) of the respective firearm (A), and a second portion (4) facing the side opposite with respect to the first portion (3), optionally suitable for bearing upon at least one portion of the structure (S) of the firearm (A).

Abstract: An obturator (100) for firearms comprises: a structure (101); a closing head (102), in particular a rotary one, arranged at an end (103) of the cylindrical structure (101); at least a resting surface (104) defined on the closing head (102) to engage the bottom (F) of at least one cartridge (C); at least one through channel (105) extending longitudinally through the cylindrical structure (101) for operatively engaging at least one striker of the firearm. The obturator comprises deformation means (108) associated with the closing head (102) to at least partially deform a firing capsule (109) and/or a bottom of a cartridge (C) loaded on the firearm.
