Method for applying a coating layer to a tubular intraluminal implant, in particular to a vascular support (stent), where the surface of the implant is perforated by a plurality of apertures, and where the coating layer is produced by deposition of material onto the surface of the implant. The implant is first pushed onto a cylindrical holder 4, a sacrificial material, in particular copper, is then deposited onto the surface of the implant until the deposited sacrificial material almost entirely fills the apertures, the coating layer is then deposited onto the surface of the implant provided with sacrificial material, and then the cylindrical holder 4 and the sacrificial material situated in the apertures 3 are removed.

A method is disclosed for operating an actuator having a coil and a displaceably mounted armature driven by a magnetic field generated by the coil, in a measurement operating mode for ascertaining a time at which the armature reaches its stop position after activation of the actuator. The method includes applying to the coil an actuation voltage signal dimensioned such that the expected armature stop time falls in a time window in which a temporally constant voltage is applied to the coil, detecting an intensity profile of the current flowing through the coil within the time window, and determining the armature stop time, based on an evaluation of the detected current intensity profile. A method for operating such an actuator is also disclosed, wherein information about the stop time is obtained in a measurement operating mode and used in a series operating mode for optimized actuation of the actuator.

For an information carrier (1) for magnetically attaching to an object (8) to be marked, according to the invention the information carrier (1) is provided with a contact-breaking surface (4), which is connected to a contact surface (2) of the information carrier (1) at an angle, wherein the contact surface (2) enables the information carrier (1) to magnetically adhere to the object (8) to be marked. By tipping the information carrier (1) onto the contact-breaking surface (4) by means of a corresponding device, the information carrier (1) can be removed from the object (8) to be marked.
摘要:
A system is arranged to remove carbon dioxide (CO2) from a gas stream by bringing the gas stream into contact with a circulating ammoniated solution stream such that CO2 is removed from the gas stream by the ammoniated solution stream. A method of removing non-volatile compounds from the circulating ammoniated solution stream includes: introducing a portion of the circulating ammoniated solution stream into a gas-liquid separating device; and separating the introduced ammoniated solution into an ammonia rich gas phase and a liquid phase comprising the non-volatile compounds; and reintroducing the ammonia rich gas phase into the circulating ammoniated solution stream.

A fluid power valve module has a supply port for fluid and at least one fluid power and more especially pneumatic valve able to be controlled via the control interface of the valve module for control of a fluid power instrumentality by way of power ports on the basis of the supplied fluid. There is a provision such that the valve module comprises at least one switching output integrated in its housing fo output of a switching signal for switching a switching means for influencing and more especially deactivating the instrumentality.
摘要:
A method for operating a printing press, which enables a uniform print quality to be achieved during long periods of operation without replacement of the impression cylinder. The printing press comprises several printing units having impression cylinders and a sheet turning device disposed between the printing units. The circumferential surface of the impression cylinder has an ink-repelling surface. The printing press is used to print sheets, until the ink-repelling surface of the circumferential surface of the impression cylinder has been worn away to an extent that the ink-repelling effect is less than a predetermined threshold value, after which a foil, of which the side facing away from the circumferential surface has an ink-repelling surface, is removably placed on the circumferential surface of the impression cylinder.
