摘要:
A method for vibration damping and shape control of a suspended metal strip during continuous transport in a processing facility in a steel rolling line or surface treating line in a steel mill, where the method comprises the steps: measuring distance to the strip by a plurality of non-contact sensors; and generating a strip profile from distance measurements; decomposing the strip profile to a combination of mode shapes; determining coefficients for the contribution from each mode shape to the total strip profile; and controlling the strip profile by a plurality of non-contact actuators based on a combination of mode shapes.

A machine for automatic sealing of sterile bottles in a bottle filling plant is proved enabling high capacity. The machine has fluid powered means to axially displace a die forming means between a position above said bottle and a position surrounding a cap in the bottle mouth. Telescopically displaceable means are also provided to close said die forming means radially around the neck of said bottle and, after execution of said sealing, to open said die forming means radially. The machine also includes telescopically displaceable plunger means to apply axial pressure towards the top of the cap pressing it down into the die forming tool against the action of a resilient plug in the mouth of the bottle.
摘要:
A filling device for sterile filling of containers. A flexible temporary storage container is placed in a dosage chamber and exposed to external over-pressure and under-pressure, respectively. The filling goods is sucked into the temporary storage container and pressed out to the final storage container. A device for fine adjustment of the volume of the chamber has the shape of an adjustable membrane. The temporary storage container can be made of two semi-spheres, of which one is rigid and the other flexible. The flexible part forms a membrane having an area equal to the inner area of the rigid semi-sphere. In order to promote natural rolling of the membrane on the inner surface of the rigid semi-sphere, the membrane has reduced wall thickness in a direction towards the margin thereof.
摘要:
A device and a method for visual monitoring and stabilization of an elongated metallic strip during continuous transport of the strip in a transport direction along a predetermined transport path, wherein the strip has been coated with a metallic layer by the strip having continuously passed through a bath of molten metal. The device includes an electromagnetic stabilizing device with at least one first pair of electromagnetic stabilizing means arranged on each side of the predetermined transport path, and a wiping device for wiping off superfluous molten metal from the strip by applying an air current in a line transversely of the transport direction of the strip and across essentially the whole width of the strip. A first image-reading apparatus takes images of the actual position of the strip in relation to the predetermined transport path. A second and third image-reading apparatus take images of the surface of the strip.
摘要:
A control system for regulating the flow of liquid metal in a device for casting a metal. A detector measures a process variable. A control unit evaluates data from the detector. At least one process parameter is automatically varied in order to optimize casting conditions. The detector measures a characteristic of the meniscus at at least two points on the meniscus instantaneously throughout the casting process.

A device for epitaxial growth of objects by Chemical Vapor Deposition on a substrate comprises a susceptor adapted to receive the substrate and members for heating walls of the susceptor surrounding the substrate and thereby the substrate and a gas mixture fed to the substrate for the growth. The device comprises also members for holding the substrate in the path of the gas mixture through the susceptor at a distance from internal walls thereof.
摘要:
A device and a method for stabilizing an elongated metallic strip of a magnetic material when coating the strip with a metallic layer. The strip is transported from the bath in a direction of transport along a predetermined transport path. A wiping device for wiping off superfluous molten metal from the strip applies an air flow in a line across the strip, where the wiping device includes at least one pair of air-knives arranged with one air-knife on each side of the strip. An electromagnetic stabilizing device stabilizes the position of the strip with respect to the predetermined transport path. A sensor detects the position of the strip in relation to the predetermined transport path.
