Abstract: A method includes manufacturing a sheet-type substrate having a security thread in which a security thread having features spaced apart from one another in the longitudinal direction of the security thread is inserted into the substrate in such a way that it is at least partially embedded in the substrate. At least one of the features is displayed as an image after the embedding of the security thread. The stretch of the embedded security thread in the longitudinal direction is calculated based on the image of the at least one feature, and the region of the substrate in which the calculated stretch of the security thread exceeds a specified maximum stretch is obliterated depending on the calculated stretch.

Abstract: A compressor for generating compressed air in a vehicle includes at least one piston, a cylinder, a crankshaft, a lubricant connection, a lubricant supply channel, and a clutch device by means of which the crankshaft can be connected to or disconnected from a drive device. The lubricant supply channel opens into at least one lubricant outlet in the interior of the compressor directed toward a piston running surface of the cylinder at least in particular rotational positions of the crankshaft.

Abstract: A compressor cylinder head with a cylinder head housing (6) and at least one pressure valve (18) has an associated pressure valve channel (17) in the cylinder head housing (6). The pressure valve channel (17) connects a compression chamber (8) arranged below the compressor cylinder head to a pressure chamber (16) inside the compressor cylinder head. Further, the compressor cylinder head has one or more channel portions with a first coolant channel system (24) inside the cylinder head housing (6), which can be filled with a coolant that flows around the pressure chamber (16). Via a casting method, the cylinder head housing (6) is produced integrally with the first coolant channel system (24) arranged therein, and further coolant channels (34) are arranged on either side of the at least one pressure valve channel (17).

Abstract: The present invention relates to a method for manufacturing a sheet-type substrate having a security thread, especially a banknote paper having a security thread, in which a) a security thread having features spaced apart from one another in the longitudinal direction of the security thread is inserted into the substrate in such a way that it is at least partially embedded in the substrate, b) at least one of the features is displayed as an image after the embedding of the security thread, c) the stretch of the embedded security thread in the longitudinal direction is calculated based on the image of the at least one feature, and d) the region of the substrate in which the calculated stretch of the security thread exceeds a specified maximum stretch is obliterated depending on the calculated stretch.

Abstract: The invention relates to a compressor (1) for generating compressed air in a vehicle, having at least one piston (6, 7), a cylinder (8, 9), a crankshaft (12), a lubricant connection (14) and a lubricant supply channel (13, 15 16, 20, 21), and having a clutch device (3) by means of which the crankshaft (12) of the compressor (1) can be connected to or disconnected from a drive device, wherein the lubricant supply channel (13, 15 16, 20, 21) opens into at least one lubricant outlet (22, 23) provided in the interior of the compressor (1) and directed toward a piston running surface (19) of the cylinder at least in particular rotational positions of the crankshaft (12).

Abstract: The invention relates to a security paper for manufacturing security or value documents, such as banknotes, identification cards and the like, having at least two through openings (12, 16). According to the present invention, a first (12) of the through openings is produced during paper manufacture and exhibits characteristic irregularities in the edge region (14), while a second (16) of the through openings is produced after paper manufacture, by cutting or punching, having a sharply delimited edge region (18).

Abstract: A mounting cylinder (1) for mounting cylindrical embossing tools for embossing rolls for embossing diffraction gratings or holograms includes a mounting shell (3) for mounting the embossing tool and a fixing device for fixing the mounting shell (3) on a shaft (2) and a tempering device for tempering the mounting shell. According to one variant, the embossing tool is expanded by compressed air in order to be slipped onto the mounting shell or removed therefrom, a compressed air channel system (8) with radial compressed air discharge openings (11) extending axially and/or tangentially within the mounting shell (3). According to another variant, the mounting shell is expanded mechanically in order to fix a embossing tool slipped over the mounting shell and simultaneously fix the mounting shell (3) on the shaft (2).
