Abstract: In a method for generating an image on a land surface by means of an applicator (11), the applicator (11) is first moved on a first place on the land surface and the position of the applicator (11) is determined. Depending on the thus determined position, a marking substance is then applied to the land surface. Finally, the applicator (11) is moved to another place on the land surface. A device for generating an image on a land surface comprises locating means (8.1, 8.2, 9) for locating a position of the device, application means (11) for applying a marking substance to the land surface and control means (9) for automatically controlling the application means (11) depending on the thus determined position.

Abstract: A one-piece attachment for a general-diffuse miniature reflector has either the lamellae resting upon the rim of the reflector and engaging behind it with formations on the lamellae, or a support ring with handle like elements engaging the rim form behind, the lamellae or blades being connected by trips with the ring so that the lamellae are all integral and in one piece with one another.
