Abstract: A mechanism for holding a barrel in a mortar unit having a ring calibrated in relation to the diameter of the barrel is disclosed. The ring has a tightening mechanism for locking or releasing the ring and the barrel of the mortar. The ring also has a mechanism for avoiding an involuntary release between the barrel and the ring resulting from firing vibrations. Such a mechanism makes it possible to change the firing angle exclusively by manipulating the tightening mechanism without the need for disassembling or handling the ring-barrel assembly.The tightening mechanism is made up of a shoe guided in the ring and movable radially to the barrel by a cam activated by a tightening lever.The mechanism for avoiding an involuntary loosening is made of several pressure washers which press against the shoe. They exert a pressure which can be be regulated by a screw. Several springs are mounted in the screws of the pressure washers and counteract the firing vibrations.

Abstract: A door blocking device comprises a bar, which extends along the edge of the door jamb, and a formed section for housing the bar, which formed section is fast with said edge and so shaped as to allow the bar to move, with only a small amount of friction, under the control of an actuating member, between a door blocking position and a door releasing position. The bar is equipped with means for returning it to the blocking position, and the actuating member drives it against the returning force in order to bring it in the releasing position. The blocking bar is equipped with a locking device comprising an elongated flat rod which, by a pivoting movement under the action of return springs, takes up a slanted position behind the bar and locks it in the door-blocking position. The bar actuating member can drive said bar back to the releasing position after controlling the retraction of the flat rod by means of a bent lever pivoting through the bar.
