Abstract: A method of manufacturing a battery is provided. A cathode assembly is provided, including a cathode and a cathode tab. The cathode tab is welded to a positive terminal of the battery. The welding is made in a circular movement.

Abstract: The present invention relates to a toothbrush attachment for an electric toothbrush, having a preferably tube-shaped body part on which an electronic module, such as a transponder, is mounted. The invention further relates to a method for producing such a toothbrush attachment and to a toothbrush having such a toothbrush attachment. According to the invention, the at least one electronic component is welded into the toothbrush attachment. According to the invention, the electronic component is encapsulated in an intermediate space between two body parts of the toothbrush attachment and is closed by at least one weld seam bonding the two body parts to each other. This ensures comprehensive protection of the electronic component by the body parts covering it.

Abstract: A method of manufacturing a battery is provided. A cathode assembly is provided, including a cathode and a cathode tab. The cathode tab is welded to a positive terminal of the battery. The areas to be welded are cleaned prior to welding to remove an oxide layer.

Abstract: The invention pertains to a method for locally heating an object with electromagnetic radiation and substantially simultaneously cooling the immediate vicinity of the object region to be heated by a flowing fluid. The inventive method is characterized in that the flowing fluid and the electromagnetic radiation emitted in the toward the region to be heated are guided along paths that are spatially separated from one another.

Abstract: An electric pressing iron in which a plate-shaped soleplate made of an aluminum material with a low silicon content is bonded to the iron body by a temperature-resistant adhesive, wherein the surface of the soleplate is provided with a hard and wear-resistant aluminum oxide coating. Because the soleplate is made of an aluminum material with a low silicon content, anodizing produces an aluminum oxide coating of a particularly uniform coloring, with a temperature-resistant as well as corrosion- and scratch-resistant ironing surface that affords particular economy of manufacture.
