  • Patent number: 7886649
    Abstract: A modular weapon system of a preloaded recoilless gun including a barrel provided with a shell, a propellant charge and a countermass. The weapon system is configured in two parts including a first part of the barrel and a second part of the barrel. The first part of the barrel includes the shell and the second part of the barrel includes the propellant charge and countermass. A releasable locking device interconnects the second part of the barrel with the first part of the barrel.

  • Publication number: 20100282054
    Abstract: An arrangement for a weapon including a countermass for reducing the pressure around the weapon. The countermass is enclosed in a container, which is mountable in the barrel of the weapon behind an ammunition part. The container is provided with an openable bottom with break indications. A guiding folding support, configured as an annular element, is arranged adjacent to the openable bottom on the outside of the bottom relative to the countermass container. The annular element is provided with a support member for each openable flap forming part of the bottom. Thereby, the opening area in the bottom of the counter mass container is defined by folding edges, formed in each base region of the flaps in the open state as in contact with its corresponding support member.

  • Patent number: 7353739
    Abstract: An arrangement for a weapon including a countermass for reducing the pressure around the weapon. The countermass is enclosed in a countermass container that can be opened at both ends. The invention aims to bring about a symmetrical opening with favorable recoil in a better way than in previous constructions. This is achieved by the countermass including elements that can bind and retain the liquid symmetrically in a desired geometry over the cross section of the barrel and the cross section of any following expansion part.

  • Patent number: 7191693
    Abstract: An arrangement for a weapon including a countermass for reducing the pressure around the weapon. The countermass is enclosed in a countermass container with an openable cover provided with break indications. The arrangement brings about a symmetrical opening operation with favorable recoil in a better way than in previous constructions. This is achieved by the introduction of a guiding folding support arranged adjacent to the openable cover on the inside of the cover relative to the countermass container.

  • Patent number: 7013593
    Abstract: The invention relates to a holder device configured for fastening to a substantially cylindrical body, such as a gun barrel, for the support of equipment such as a sight. The holder device comprises at least two holder elements, one holder element being configured for secure fixing to the cylindrical body and the other one being arranged such that it is movably coupled to the first-named holder element. According to the invention, the holder elements are arranged such that they are rotatable in relation to each other about a common axis between a first position, the transport position, and a second position, the activated position, and one of the holder elements is axially displaceable along the common axis from a position of equilibrium defined by a spring arrangement. The holder device reduces the transmission of axial recoil motions between the holder elements.

  • Patent number: 5337594
    Abstract: An apparatus is a press line includes presses along a material flow direction for stepwise processing of a workpiece. A transfer device moves each workpiece from one press to the next in the press line. The transfer devices are displaceable transversely of the press line. Further, a carriage is included for each press for transport of tools, the carriage being drivable along tracks. To permit rapid tool change and maximum utilization of the space surrounding the press line, the carriage is provided with a first end portion fitted with equipment for transport of a tool to or from a press, and with a second end portion which carries the transfer device so that this projects cantilevered out from the carriage.

  • Patent number: 4593620
    Abstract: Propellant charge component for use with a projectile (4) for muzzle-loaded weapons. The propellant charge component (5) and the projectile (4) are each capable of being loaded into the weapon separately. The propellant charge component (5) is provided with a piston (14) which is capable under the effect of gases from the propellant charge component (5) of being separated from the propellant charge component (5) in the direction of firing of the projectile until it comes up against a stop organ (17) arranged on the propellant charge component (5), whereby the impact against the stop will impart kinetic energy to the propellant charge component (5) causing it to be ejected from the weapon.
