Abstract: The invention relates to a heat transfer device (1) having a sleeve (4) closed on all sides, wherein the sleeve (4) defines a volume in which one insert element (3) or multiple insert elements (3) made of a sintered material is/are arranged to form at least one heat pipe, wherein at least one channel (2) for a heat transfer medium is formed in the sintered material, and the sleeve (4) is at least partially formed from a single-layer or multi-layer film (5, 6).

Abstract: The invention relates to a primer cap for small-caliber ammunition, having an outer metallic cup in which is arranged a priming composition which generates hot combustion gases following initiation. To enable more versatile control of the initiation process in the weapon, it is proposed that a resistance bridge which can be initiated electrically, and an electrically conductive pole piece, are additionally arranged in the primer cap, wherein the first pole of the resistance bridge is connected to the cup and the second pole is connected to the cup and the second pole is connected to the pole piece, which protrudes out of the cup and is electrically insulated from the same.

Abstract: There is described an RF communication device, the device comprising (a) a data memory for storing data, (b) an RF interface (112) for RF communication with an external RF device (130), (c) a host interface (111) for communication with a host device (120), (d) a host access memory unit (214, 215) comprising host interface access control data, the host interface access control data defining host access rules for accessing data in the data memory through the host interface (111), and (e) a host access control unit for, based on the host interface access control data, controlling access to data in the data memory through the host interface (111). There is also described a system and a method.

Abstract: The invention relates to a friction disc (10) with a disc body (5, 9) which has at least one vibration damping element (13), which consists of at least one elastomer or comprises the latter.

Abstract: Disclosed is a bullet and practice cartridge for use on a shooting range having a cylindrical rear part and an ogive region at the nose end. The ogive region has a rear end and a bullet tip. In order that the bullet behaves like a conventional full metal jacket round nose bullet in a soft target, and moreover has a low energy output in the soft target, that the bullet does not deform or splinter in soft materials, and that the bullet does not puncture protective materials of bullet catchers, the bullet is constructed in one piece, the ogive region is closed all round a cavity and the wall thickness of the ogive region decreases constantly from the rear end to the tip.
