Abstract: The invention relates to a light curing appliance, in particular a dental light curing appliance (10), with a light source and with a light emission element such as an optical waveguide (12), of which the light output end is intended in particular to be directed towards a material that is to be polymerized. It is provided with one or more control devices (16) for switching on the light source during a polymerization cycle, and with one or more sensors (20) or sensor combinations connected to the control devices (16). The sensor (20) is designed as a location sensor and/or as a motion sensor (20) which detects a movement of the light curing appliance (10), designed as a hand-held appliance, and sends signals reproducing the motion to the control devices (16).

Abstract: The invention relates to a dental restoration production device, comprising a curable dental restoration material (20) and a radiation-curing device by means of which the curable dental restoration material (20) can be cured using light radiation, UV radiation and/or heat radiation in order to produce a dental restoration part (22), and comprising an add-on (24) or attachment to the radiation-curing device, which faces said dental restoration material (20) or can be directed thereto, wherein said attachment or add-on (24) has a molding surface that corresponds to the target shape of the surface (52) of the dental restoration material (20) and forms a negative mold (54) therefor on the region facing the radiation-curing device.

Abstract: The invention relates to a compressed air tank for utility vehicles, comprising a tubular or cylindrical jacket sealed at both ends by way of welded outer bases. At least one outer base and/or the jacket is provided with a hole. A sleeve is welded onto the hole. At least the inside of the compressed air tank is provided with an inner coating. The contact surfaces between the jacket and the outer bases are adapted such that the contact surfaces abut one another and such that the contact surfaces can be welded together without using any weld material through laser welding. The sleeve is welded onto the hole by way of laser welding or CD welding. The inner coating of the tank is manufactured by powder coating.

Abstract: A container for operating media of motor vehicles which is chemically stable both in respect of the fuel carried and in respect of additives.

Abstract: A gasket is provided that is suitable for use in connection with a cylinder head. The gasket includes a first outer plate including a compensating portion, a second outer plate including a compensating portion, and a compensating plate positioned between said first and second outer plates. Preferably, at least one of said first and second outer plates includes a bead positioned outside of, and in close proximity to, said compensation portion of said plate. The compensating plate includes a compensating element and an edge portion. In a preferred embodiment, the area between the compensating portions of said first and second outer plates defines a compensating area and said compensating element is positioned within said compensating area. If desired, the gasket may also include a spacer plate.
