Abstract: The invention relates to a nozzle for cold gas spraying in which gas and spraying particles are accelerated. According to the invention, the cold gas spraying nozzle is at least partially coated at its inner wall.

Abstract: A cold gas spray gun is disclosed. The spray gun includes a high-pressure gas heater which has a pressure vessel through which gas flows and a heating element situated in the pressure vessel, as well as a mixing chamber in which particles can be admixed with the gas through a particle feed. A Laval nozzle is arranged downstream in the direction of flow of the gas and consists of a convergent section, a nozzle throat and a divergent section. The high-pressure gas heater and/or the mixing chamber is/are at least partially insulated on the inside in the areas of contact with the gas.

Abstract: A process for manufacturing metallic objects such as films, sheet metal or moldings, with a photocatalytically active surface through the application or introduction of photocatalytically active material by means of cold-gas spraying technology is disclosed. To increase the durability of the layer, the spray material contains oxide ceramics and a metallic powder.

Abstract: The invention relates to a miniaturized gas chromatograph and injector for the same. Said micro-GC is compact and simple and economical to construct. Dead volumes are largely avoided in order to achieve reliable and reproducible measured results. Said miniaturized gas chromatograph comprises at least one injector, one separation column and a detector which are combined on a circuit board to give a gas chromatography module. The injector comprises a first sheet with channels, which is provided with a second sheet with channels and which may be displaced relative to the latter, whereby at least one of the sheets provided with a layer of plastic, in particular a chemically inert plastic on the side of the sheet facing the other side.

Abstract: A method and a device for cold gas spraying. According to the invention, energy is supplied to the particles with microwave technology. For that purpose, the nozzle in which the gas jet and particles are accelerated is surrounded by a microwave waveguide and/or a/the microwave waveguide encloses at least in part the spray-free jet between the nozzle outlet and the substrate. Advantageously, one section of the nozzle outlet is made of a ceramic.

Abstract: A passenger cabin of a passenger transport vehicle such as an aircraft includes single passenger seats arranged between an aisle and an outside cabin wall. Each seat is tiltably adjustable between an upright seating configuration and a reclined lying configuration, and is rotatable between a forward-facing orientation facing 0 to 18° relative to the cabin longitudinal axis, and an inwardly-turned orientation facing 50 to 60° relative to the longitudinal axis. The forward-facing orientation is for upright seating during take-off and landing. The inwardly-turned orientation provides additional leg room and sufficient space for the reclined lying configuration. The pitch spacing between seats can be minimized, and total seating capacity is high, while providing substantial space and comfort for each passenger. Screening partitions adjacent to the cabin wall and the aisle provide privacy screening and define a personal space allocated to each seat.

Abstract: A reclinable seat includes a seat bottom with a seat frame, and a backrest with a backrest frame pivotably connected to the seat bottom to be adjustable to an upright seating configuration and a reclined lying configuration. The seat bottom includes a support arrangement having an adjustable firmness. A firmer support is provided in the upright seating configuration, and a softer support is provided in the reclined lying configuration. In the support arrangement, seat support rods extend across the seat bottom and are pivotably supported on the seat frame. A shaft is connected to the backrest frame. Straps are connected to the shaft and to each of the seat support rods while weaving over and under the rods. When the recline angle of the backrest is adjusted, the shaft rotates and either pulls or slackens the straps to pivot the support rods between a firmer orientation and a softer orientation.

Abstract: A passenger cabin of a passenger transport vehicle such as an aircraft includes single passenger seats arranged between an aisle and an outside cabin wall. Each seat is tiltably adjustable between an upright seating configuration and a reclined lying configuration, and is rotatable between a forward-facing orientation facing 0 to 18° relative to the cabin longitudinal axis, and an inwardly-turned orientation facing 50 to 600 relative to the longitudinal axis. The forward-facing orientation is for upright seating during take-off and landing. The inwardly-turned orientation provides additional leg room and sufficient space for the reclined lying configuration. The pitch spacing between seats can be minimized, and total seating capacity is high, while providing substantial space and comfort for each passenger.
