  • Patent number: 10736503
    Abstract: A method of determining at least one selection parameter for selecting an intraocular lens to be inserted into an eye; the method comprises reading, by a data processing system, data indicative of an axial position of at least a portion of an anterior surface of an at least partially empty capsular bag of the eye, relative to an optical axis of the eye. The method further comprises determining an axial position parameter, which is representative of the axial position of the portion of the anterior surface, depending on the data. The method further comprises determining the at least one selection parameter for selecting the intraocular lens depending on the determined position parameter.

  • Patent number: 10682051
    Abstract: A system for performing a surgical procedure includes an OCT unit for scanning an object region volume with an OCT scanning beam and a control unit for setting the position of the object region volume. A surgical instrument having an effective section is arrangeable in an object region of the object region volume and is localizable in the object region volume with the OCT unit. A computer unit has a first computer program for determining the position of the effective section by processing scan information obtained by scanning the object region volume and a second computer program compares the scan information to reference data and provides a set value for the position of the effective section. The second computer program determines deviation information as to the spatial deviation of the effective section from the set value.

  • Patent number: 8445808
    Abstract: Methods for arc welding unalloyed or low-alloy steels with consumable electrode under protective gas are suggested, in which the protective gas is a mixture comprising at least helium and an active gas as well as a further inert gas. In the general case, the proportion of the active gas in the total volume of the protective gas is to be in the range from more than 0.5% to approximately 1.5% and the proportion of helium in the total volume of the protective gas is to be more than 30%. In case an electrode having a lowered or medium Si content of approximately 0.2% to approximately 0.4% is used, the proportion of the active gas in the total volume of the protective gas is to be approximately 1% to approximately 5%. If an electrode with a low Si content of approximately 0.05% to approximately 0.1% is used, the proportion of the active gas in the total volume of the protective gas is to be approximately 3% to approximately 10%.

  • Publication number: 20090236319
    Abstract: A method for joining at least two objects by a joining means selected from resistance welding, resistance soldering and a magnetically impelled arc, in which the objects are brought into contact with one another in the area to be joined, such that the objects are joined to one another in a particularly stable and/or particularly homogenous fashion and oxidation of the area to be joined is reliably prevented. The respective base metal of the objects is fused at least in the contact area, and in that at least one inert gas and/or at least an inert gas mixture is supplied at least to the contact area of the objects such that the fusing of the respective base metal takes place under an inert gas atmosphere.

  • Publication number: 20090014422
    Abstract: According to the invention a welding device for welding workpieces is provided. The welding device comprises a welding means for making a welding seam on workpieces and a cleaning nozzle in order to emit a cryogenic medium onto the surfaces of the workpieces in the area of their welding seam to be formed. The distance between the welding means and the nozzles is at least 5 cm.

  • Publication number: 20080272098
    Abstract: To refine a method for electric arc joining, in particular for M[etal] P[rotective] G[as] welding and/or for M[etal] P[rotective] G[as] soldering, of at least one object made of metal and/or at least one metal alloy under protective gas using at least one meltable electrode, at least one mixture made of argon, helium, and at least one active gas being supplied as the protective gas, in such a manner that arbitrary electric arc joining technologies, in particular M[etal] P[rotective] G[as] welding and/or M[etal] P[rotective] G[as] soldering, may be performed in parallel and/or in sequence using the supplied protective gas, it is suggested that the protective gas have helium in a range from approximately 25 volume-percent (vol.-%) to approximately 30 vol.-%, carbon dioxide, oxygen, or a carbon dioxide-oxygen mixture in a range from approximately 0.5 vol.-% b to approximately 0.9 vol.-%, and argon in the remaining volume range.

  • Publication number: 20070045237
    Abstract: A method of arc-joining a workpiece with a consumable electrode and with the use of an inert gas shield and a short arc is disclosed. Material is dispensed by the melting electrode to the workpiece while an electronically controlled electrical short circuit is formed. An inert gas is used that consists of 50 to 5000 vpm (0.005 to 0.5 vol. %) of oxygen, carbon dioxide, nitrogen monoxide, nitrogen, dinitrogen monoxide, or of a mixture of these gases, in argon or in an argon/helium mixture.

  • Publication number: 20060243704
    Abstract: A method and apparatus for protective gas welding using at least two consumable electrodes to which at least two different potentials are applied is disclosed. A common weld pool is formed by one leading electrode and at least one trailing electrode. When two electrodes are used, this method is also referred to as tandem welding. A larger electrode diameter is used for the leading electrode in comparison with the trailing electrode. Furthermore, a protective gas mixture consisting of 3 to 40 volume % carbon dioxide and/or oxygen and argon and optionally helium is used.

  • Patent number: 5176761
    Abstract: Surfaces of structural components made of aluminum or aluminum alloys are chemically treated to produce an aluminum oxide coating for improved adhesive bonding to other components or to other surface layers. The oxidizing is accomplished by exposing the surface to be oxidized to a combination bath of an inorganic mineral acid and an oxidation medium for a specific time duration, so that an oxide coating is produced on the surface of the structural components, as a prerequisite for a good adhesion stability of adhesive bonds to be formed after oxidizing.
