Abstract: The invention relates to a coating lance for a plasma process, the lance comprising a plasma shaft, a plasma neck, and a plasma head, the plasma shaft comprising a longitudinal channel, which extends in an axial direction along an axis from a first shaft end to a second shaft end, the plasma neck comprising a shaft boss and a head boss and at least one neck channel, which extends from the shaft boss to the head boss, and the shaft boss being arranged on the second shaft end in such a way that the longitudinal channel leads into the at least one neck channel, the plasma head comprising a neck boss, a plasma opening, and at least one head channel, which extends from the neck boss to the plasma opening, and the neck boss of the plasma head being arranged on the head boss of the plasma neck in such a way that the at least one neck channel leads into the head channel.

Abstract: A rotary feedthrough for the feedthrough of a powder-gas mixture from a stationary machine part into a rotating machine part, with a seal in the form of two flat circular-ring-shaped sliding seal surfaces arranged one on the other in a sliding manner, which sliding seal surfaces are arranged concentric to the axis of rotation of the rotating machine part and which can be moved apart from each other in the axial direction, so that they form a gap, wherein the seal is embedded in a purge chamber having at least one gas inlet and at least one gas outlet.

Abstract: Method for coating components by thermal spraying, wherein not the entire surface of the component is to be coated and wherein those parts of the surface that are not to be coated are covered by masking before coating and wherein the covering is made by a paste processes at least in the areas of critical mask boundaries, i.e. by way of a paste dispensed from at least one nozzle, wherein the paste is a curable paste and curing is photo induced and preferably made by way of UV radiation, characterized in that the masking utilizes a partial masking step and a complementary masking step, the complementary masking step being performed at least in the area of critical mask boundaries and the partial masking step being performed in an area spaced from the area of critical mask boundary and the method of partial masking is not a paste process.

Abstract: The invention relates to a coating lance for a plasma process, the lance comprising a plasma shaft, a plasma neck, and a plasma head, the plasma shaft comprising a longitudinal channel, which extends in an axial direction along an axis from a first shaft end to a second shaft end, the plasma neck comprising a shaft boss and a head boss and at least one neck channel, which extends from the shaft boss to the head boss, and the shaft boss being arranged on the second shaft end in such a way that the longitudinal channel leads into the at least one neck channel, the plasma head comprising a neck boss, a plasma opening, and at least one head channel, which extends from the neck boss to the plasma opening, and the neck boss of the plasma head being arranged on the head boss of the plasma neck in such a way that the at least one neck channel leads into the head channel.

Abstract: The invention relates to a coating method for coating a curved surface (1), in particular a concave inner surface (1) of a bore wall or a cylinder wall (2), by means of a powdery coating material (3) by using a thermal spraying device, in particular a plasma spraying device (4) or a HVOF spraying device. A gun (6) is provided on a gun shaft (5) of the thermal spraying device (4) for generating a coating jet (7) from the powdery coating material (3) by means of an arc and the gun (6) is rotated about a shaft axis (A) of the gun shaft (5) at a predetermined rotation frequency (N), wherein the coating jet (7) for applying a coating (8) to the curved surface (1) is directed at least partially radially away from the shaft axis (A) towards the curved surface (1).

Abstract: The present invention relates to a method for coating components by thermal spraying, wherein not the entire surface of the component is to be coated and wherein those parts of the surface that are not to be coated are covered by masking before coating, characterized in that the covering is made by means of paste processes at least in the areas of critical mask boundaries, i.e. by means of a paste dispensed from at least one nozzle.

Abstract: The present invention relates to a novel composition comprising danielone and derivatives thereof as well as to the use of such compositions in skin lightening. More particularly, the present invention relates to danielone and derivatives thereof for use in topical compositions for smoothening skin color irregularities, for reducing melanin formation in the human skin, for lightening/brightening human skin and/or for treatment of pigmentation disorders which comprises topically administering an effective amount of danielone and derivatives thereof to the appropriate skin area of a person in need of such beautifying agent, or treatment.

Abstract: Cosmetic composition which can be applied topically, comprising at least one compound of the general formula (I) in which R1 is H, C1-C20-alkyl, cycloalkyl or aryl-C1-C4-alkyl, n is 1-4, X is —O—, —NH— or —NR2— and R2H or C1-C20-alkyl; and at least one compound corresponding to the above formula (I) but in which XR1 with X having the possible meaning of —NH— is the residue of an alpha-amino acid; use of these compounds and of the composition for stimulating the synthesis of the proteins of the basement membrane; and also both those compounds of the formula (I) in which X is —NR2— and both R1 and R2 are different from H, and the compounds corresponding to formula (I) but in which XR1 with X having the possible meaning of —NH— is the residue of an alpha-amino acid, as such.

Abstract: Topical composition for use especially as a skin lightener, characterized in that it contains an effective amount of at least one compound of general formula (I) or a mixture of such compounds and/or an acid addition salt thereof: in which X is NH or a direct bond and n is 2, 3 or 4, preferably 2 or 3, and its use for lightening skin colour, for depigmenting liver spots and for evening out non-uniformities in skin colouration. The invention further relates to dermatologically effective compositions containing at least one disulfide of general formula (I) and at least one additional skin care ingredient.
