Disclosed is a method for producing a permanently joined plate heat exchanger comprising a plurality of metal heat exchanger plates having a solidus temperature above 1100 C., provided beside each other and forming a plate package with first plate interspaces for a first medium and second plate interspaces for a second medium, wherein the first and second plate interspaces are provided in an alternating order in the plate package. Each heat exchanger plate comprises a heat transfer area and an edge area which extend around the heat transfer area. The heat transfer area comprises a corrugation of elevations and depressions, wherein said corrugation of the plates are provided by pressing the plates. Also disclosed is a plate heat exchanger produced by the method.

Ophthalmic lenses and method of manufacturing ophthalmic lenses that include automated steps are disclosed.

The present invention relates to a method for cutting a polarizing plate using a laser, in which a beam shape of the laser is an elliptical shape and a major axis of the elliptical shape is parallel to a cutting direction, and a polarizing plate cut using the same.

A rotatable connection between a first component and a second component, the rotatable connection comprising: a first connecting piece composed of metal and which is to penetrate the first component over at least the entire thickness of the first component, in which at an end facing the second component, the first connecting piece is welded to the second component.

A cassette for a bicycle may include a plurality of sprocket portions joined together into a single unit. The cassette may include a cavity formed in the large end of the cassette. A related manufacturing method may include joining a first generally planar sprocket portion having a plurality of connector portions extending transverse to the plane of the first sprocket portion, to a second generally planar sprocket portion, e.g., by fusing at least one of the connector portions to the second sprocket portion.

The present invention discloses a method for the controlled guidance of corrosion by the action of a laser beam. This method enables the selective adjustment of the speed of corrosion in each area of a target component and, therefore, the driving of the corrosion towards the areas of interest. With the application of this method, the corrosion process is guided by the laser treatment and becomes predictable and controllable. The method is applicable in all those sectors of activity where it is necessary to control corrosion.

Provided is a neodymium-iron-boron magnet and preparation method thereof. The preparation method includes the following steps: preparing a Fe.sub.aG.sub.b metal sheet, covering the Fe.sub.aG.sub.b metal sheet with a rare earth compound Re.sub.xM.sub.yB.sub.z layer, performing multi-layer stacking on the metal sheet covered with the rare earth compound Re.sub.xM.sub.yB.sub.z layer, and then performing high-temperature diffusion under an extrusion force with certain strength, so as to prepare a neodymium-iron-boron magnet.

A nickel-based braze alloy composition is described, including nickel, about 1 weight % to about 5 weight % boron (B); and about 1 weight % to about 20 weight % germanium (Ge). The composition is free of any silicon. Superalloy articles that contains a crack or other type of void or gap filled with the nickel-based braze alloy composition are also described, along with methods for filling such a gap. Related articles of manufacture and brazing processes to join metal components are also disclosed.

The present invention relates to a cutting tool insert including a carrier body made of maraging steel. The carrier body has at least one rake face, at least one flank face and at least one pocket, wherein the at least one cutting element is situated in the at least one pocket. The cutting element has at least one cutting edge and can be made of any material known in the art of cutting. The cutting tool insert further includes a braze joint joining the carrier body and the at least one cutting element, wherein the braze joint includes Ti and a Ti containing joining layer with a thickness of between 0.03 and 5 m adjoining to the cutting element.
