Abstract: A method for determining and/or monitoring the state of a protective cover, includes the steps of a) obtaining a first state value of at least one characteristic physical, mechanical and/or chemical property of the protective cover at a first point in time; and b) obtaining a second state value of the at least one characteristic property of the protective cover at a second point in time, which is to subsequent to the first point in time; and c) comparing the obtained state values; and d) determining the state of the protective cover based on the comparison performed in step c).

Abstract: A safety system has a valve block (10) to which at least one gas safety valve (12, 14) is connected in a detachable manner. At least one controllable valve (50, 52, 58) is in or at the valve block (10). At least one pressure accumulator (42) holds a gaseous pressure medium and is connected to the valve block (10) in a detachable manner. A gas-conveying connection routed at least partially within the valve block (10) between the connected pressure accumulator (42) and the connected gas safety valves (12, 14) can be opened or blocked by the valve (50, 52, 58).

Abstract: A drilling-milling device comprising a housing; a drive shaft; a spindle; and a brake. The drive shaft and the spindle being coupled to one another by a gear mechanism, and the brake being coupled to the spindle and a braking torque of the brake being transmitted to the housing.

Abstract: A safety system comprising a valve block (10) to which at least one gas safety valve (12, 14) is connected in a preferably detachable manner, having at least one controllable valve (50, 52, 58) in or at the valve block (10) and having at least one pressure accumulator (42) holding a gaseous pressure medium, which pressure accumulator is connected to the valve block (10) in a likewise detachable manner, is characterized in that a gas-conveying connection routed at least partially within the valve block (10) between the connected pressure accumulator (42) and the connected gas safety valves (12, 14) can be opened or blocked by means of the valve (50, 52, 58).

Abstract: The invention relates to a protective cover comprising a plurality of protective cover segments (1), which can be moved telescopically against one another and which have a covering leg (2) and a supporting leg (3), and comprising a connecting element or bellows (4). When the protective cover is telescopically extended, an elastic restoring element produces a torque (M) and transfers said torque to the supporting leg (3). The invention is characterized in that the elastic restoring element is an integral component of the connecting element (4) in that the connecting element (4) has flexural rigidity and is connected to the supporting leg (3) in a planar manner along a height portion (h) of the supporting leg (3). Owing to the invention, an additional elastic restoring element and the attachment thereof to the supporting leg are no longer necessary.

Abstract: A device for keyway broaching is provided with a housing, a drive shaft, a broaching carriage received and supported in the housing, a tool support connected to the broaching carriage, and a crank drive that couples the drive shaft and the broaching carriage with each other. The broaching carriage, when driven by the drive shaft, performs an oscillating movement comprising a cutting movement and a return stroke. A sleeve is arranged between the housing and the broaching carriage. A first seal is provided between the housing and the sleeve and/or between the sleeve and the broaching carriage. The tool support is connected to the broaching carriage with a rocking lever interposed between the tool support and the broaching carriage. The drive shaft has a control section that controls a relative movement between the rocking lever and the broaching carriage.

Abstract: The invention relates to a protective covering comprising a plurality of substantially L-shaped protective covering segments (2, 16) comprising a cover leg (3, 17) and a support leg (4, 18) which are arranged relative to one another in such a way that they are telescopically slidable with respect to one another, wherein the cover legs (3, 17) of adjacent protective covering segments (2, 16) each come to bear on one another thus forming an overall substantially closed surface, and comprising at least one band-shaped or web-shaped flexible connecting element (5, 31) which connects the support legs (4, 18) of the protective covering segments (2, 16) with each other so as to at least transfer a tensile force.

Abstract: A fuel injection device (10) for internal combustion engines, in particular a common rail injector, includes a housing (12). A high-pressure fuel connection is also provided, as is a fuel return connection (16). The latter includes a plug part (20) for connection to a fuel return line. To make the fuel injection device (10) easier to assemble, it is proposed that the fuel return connection (16) includes a socket part (18), which is secured in fuelproof fashion in a fuel return opening (20) in the housing (12) and onto which the plug part (20) is placed in fuelproof fashion.
