Abstract: A metrology device includes a sound sample holder and an optical system. The sound sample holder is provided for applying sound waves to a first substrate stack surface of the substrate stack. The optical system include a source, a lens field, a beam splitter, and a detector. The source is provided for outputting electromagnetic radiation, which is split into at least one first beam path and one second beam path. The lens field is provided for applying the first beam path to a substrate stack measuring surface of the substrate stack. The beam splitter is provided for forming an interference radiation made up of the first and second beam paths of the electromagnetic radiation. The detector is provided for detecting the interference radiation.

Abstract: A cam phaser including a stator that is driven by a crank shaft of an internal combustion engine; and a rotor that is connectable torque proof with a cam shaft of the internal combustion engine and that includes plural blades that protrude radially outward from a rotor hub, wherein operating chambers arranged between the stator and the rotor are divided into pressure cavities by the blades, wherein the stator and the rotor are configured as sintered components, wherein displacement recesses are provided on axially configured faces of the stator and/or of the rotor wherein material is configured to flow into the displacement recesses during a deforming finishing of the faces.

Abstract: The invention relates to a planar seal, in particular, a cylinder head gasket for an internal combustion engine, comprising several through openings, and several media through openings, whereby a web with at least one bead is formed between individual through openings and at least one stopper element is provided radially adjacent to the bead, for each through opening. A through drilling is provided in the web region, through the bead for the passage of media.

Abstract: A planar seal, in particular, a cylinder head gasket for an internal combustion engine, is provided with several through openings forming a web between the same, several screw and media through openings, at least one bead in the region of each through opening and each web which are contiguous, whereby at least one through drilling is provided on the web side and embodied such that the beads on the through opening side pass to both sides of the through drilling in the direction of the web and are connected to the beads running through the web in the region of the web.

Abstract: The invention relates to a flat gasket, in particular a cylinder-head gasket for internal combustion engines, comprising at least one support element, in particular a metallic element, which is provided with at least one passage on the combustion chamber side. According to the invention, the passage is surrounded by a concentric stopper element and at least one concentric elastic half-bead that is inserted into a metallic functional layer. The half-bead lies in a direct force fit against the stopper element, the latter having a greater thickness than that of the support element.

Abstract: The present invention relates to the use of a substance that inhibits the Y2 receptor of neuropeptide Y for the preparation of a pharmaceutical composition for treatment of alcoholism. It also relates to a pharmaceutical composition comprising at least one substance with activity against alcohol consumption.

Abstract: A metal cylinder head gasket includes a spacer plate; a sealing layer superposed on the spacer plate; an opening in the spacer plate and the sealing layer for surrounding a combustion chamber of an internal-combustion engine and a full bead provided in the sealing layer and surrounding the opening. The full bead has a crest, and first and second bead feet situated radially inward and, respectively, radially outward of the crest. An annular overlay surrounds the opening and is positioned between the spacer plate and the sealing layer and is in engagement with the full bead. The annular overlay has a radially inner edge face in alignment with the opening edges; and a radially outer edge face situated between the crest and the second bead foot. The sealing layer further has a half bead surrounding the full bead and being spaced radially outward from the second bead foot.

Abstract: A flat metal sealing gasket is made as follows: on an unhardened spring steel plate having an aperture and a bead surrounding the aperture, a sinterable powder is deposited along the bead in a desired shape and thickness. Thereafter a sufficiently high temperature is applied to the deposited sinterable powder to effect sintering or melting of the powder to provide a pressure-resistant overlay on the plate and to simultaneously effect a hardening of the plate.
