Abstract: The present invention relates to a device for transferring exhaust gas between a front and rear carriage of a mobile working machine, in particular a dump truck, separated by an articulated pivot joint, which working machine has a pipe section, which is variable in it length, for conducting exhaust gas, a first flexible hose cooperating with a first end portion of the pipe section for introducing exhaust gas into the pipe section, and a second flexible hose cooperating with a second end portion of the pipe section for discharging exhaust gas from the pipe section. The device is characterized in that a first cardan shaft is provided in the first end portion, the distal end of which is configured to be rigidly attached to a fastening section of the front carriage or the rear carriage of the working machine, and a second cardan shaft is provided in the second end region.

Abstract: An integral sound suppressor for a gun barrel, with the integral sound suppressor including a tubular housing designed for nearly completely or completely encasing the gun barrel along its longitudinal direction with an internal thread disposed inside the housing for mounting the integral sound suppressor on an external thread disposed on the muzzle of the gun barrel. Disposed inside the housing is a deflector system for deflecting the gas generated by firearm discharge, and disposed on the housing is a guide surface which is spaced at a distance from the internal thread along the longitudinal direction of the housing for guiding the integral sound suppressor in the region of the front end of the gun barrel.
