Abstract: The invention is based on a chip catcher for a power tool (26) that generates chips (56), in particular a hand-guided power tool (26), having an inlet region (32) for admitting a flow of air containing a chip/air mixture (52) and for detachably connecting to a chip ejector (16) and having an encompassing housing (48) that is provided for attachment to a safety guard (10). According to the invention, the housing (48) contains an air outlet (36) spatially separate from a chip-collecting region (58) for chips (56). The invention has also proposed a system comprised of the chip catcher (30) and a safety guard (10).

Abstract: A minehunting apparatus is carried by an underwater transporting drone to the mooring cable of a mine. The minehunting apparatus includes a housing and clamping levers pivotably mounted on the housing to close around the mooring cable. Inside the housing are explosives which are detonated by a coded sonar signal. To improve the maneuverability of the transporting drone, the weight of the minehunting apparatus is balanced so that the apparatus has an essentially neutral buoyancy during the transporting process in the water. After the clamping mechanism has clamped itself around the mooring cable, a lighterweight is released to cause the remainder of the minehunting apparatus to float upwardly toward the mine.
