  • Patent number: 8070024
    Abstract: A nozzle for dispensing a liquid contained in a receptacle, the nozzle including a rigid body provided with a dispensing channel including a dispensing orifice emerging in the front wall of the body, the nozzle also including an elastically deformable sleeve that is disposed in a non-adherent fashion and in clamping contact around at least part of the periphery of the rigid body, the sleeve being provided with at least one front lip that is disposed opposite the dispensing orifice, the lip being arranged so as, by application of the dispensing pressure of the liquid on it, to be reversibly movable between a stable closed state and stressed opening state of the orifice, in which the attachment of the sleeve on the rigid body is achieved in combination by a first attachment for retaining the axial movement of the rear part of the sleeve relative to the rigid body and by a second attachment for retaining the axial movement of another part of the sleeve relative to the rigid body.

  • Publication number: 20080237272
    Abstract: The invention concerns a nozzle for dispensing a liquid contained in a receptacle, said nozzle comprising a rigid body provided with a dispensing channel comprising a dispensing orifice emerging in the front wall of said body, said nozzle also comprising an elastically deformable sleeve that is disposed in a non-adherent fashion and in clamping contact around at least part of the periphery of the rigid body, said sleeve being provided with at least one front lip that is disposed opposite the dispensing orifice, said lip being arranged so as, by application of the dispensing pressure of the liquid on it, to be reversibly movable between a stable closed state and stressed opening state of said orifice, in which the attachment of said sleeve on said rigid body is achieved in combination by a first means of retaining the axial movement of the rear part of said sleeve relative to said rigid body and by a second means of retaining the axial movement of another part of said sleeve relative to said rigid body.

  • Patent number: 4708049
    Abstract: The invention is directed to an automatic firearm apparatus of the type including a feed system and a rotatable drum driven in rotation by an outer motor, wherein the drum includes a closed contour breech drive ramp. The apparatus includes two follower members cooperating with the ramp, each rigidly mounted on a breech to impart to the breech a reciprocating movement between a feed position, in which it is separate from its respective cartridge chamber, and a firing position, in which it closes the cartridge chamber. The feed system includes a feed mechanism rotating continuously and two distribution mechanisms rotating intermittently. Each of the distribution mechanisms are arranged to receive ammunition from the feed mechanism when stopped and, when rotating thereafter, to supply this ammunition to its respective breech while the latter is in its feed position.

  • Patent number: 4704945
    Abstract: The field of the invention is that of percussion devices used in automatic weapons.The invention consists of integrating the firing pin 12 with carrier piece 1 during the locking phase and then with the movable bolt head 7 during the recoil phase. The integration means consists of levers 17 pivoting on the firing pin about shaft 18 and bearing on surfaces 23 and 26 on the movable bolt head and counterpin 14, respectively.The invention finds its applications in the field of weaponry and, more particularly, in small- and medium-caliber weapons.

  • Patent number: 4612843
    Abstract: A dual ammunition feed for automatic weapons includes a positioning device for the ammunition wherein a central positioning sprocket unit interacts with two feed sprocket units in two separate feed casings to allow for loading with two different types of ammunition. The feed casings are tiltable into and out of engagement with the positioning device, the tilting of a particular feed casing into engagement with the positioning device being followed by the simultaneous disengagement of the other feed casing from the positioning device. The tilting of a particular feed casing into engagement further results in the coupling of the engaged feed casing's feed sprocket unit with a reducing transmission driven by an external motor, and in a change in the rotational direction of the central positioning sprocket unit such that the central positioning sprocket unit always rotates in an opposite direction from that of the feed sprocket unit of the particular feed casing which is engaged.
