The present invention relates to a holder for a number of drills, which can advantageously be used for coating drill tips. The holders according to the invention make it possible to arrange the drills in the coating unit in such a way that their tips rest on a cylindrical wall and these can be rotated past a coating source at the same minimum distance. The holder comprises a first curved wall with holes, a second curved wall with holes or slits and a third wall which serves as stop for drills inserted in the holes of the first and second wall.

The invention relates to a device and a method for identifying an object O in an opening that can be closed by means of a mobile element (12). Light is fed into at least one fiber-optic light guide (33, 34) from a light source (1, 2), and variations in the received light are detected by means of at least one receiver (Ea, Eb), the fiber-optic light guide being arranged at least partially along the edge of the opening (11). A first fiber-optic light guide sends light transversally to the length thereof, said light being then received by a second fiber-optic light guide transversally to the length thereof. The second fiber-optic light guide (34) is connected to the receiver (Eb). The fiber-optic light guides are arranged on the edge of the opening (11) in such a way that a light field (F) at least partially bridging the opening is produced. At least one light source (1, 2) and at least one receiver (Ea, Eb) are respectively associated with each fiber-optic light guide (33, 34), and a clock circuit is used to alternately feed the light received by the respective receiver into the fiber-optic light guides. Comparison means are used to compare the signals on the receivers in order to identify the object.

摘要:
A method is disclosed for making a forced ventilation apparatus (1) for equalizing a pressure difference between a passenger compartment and surroundings of a motor vehicle. The apparatus (1) includes a frame (2) made of hard plastics and delimiting an aperture (3), and a flat ventilation flap (7) made of an elastomer material and secured to the frame (2). A resilient restoring force counteracts opening movement of the ventilation flap (7) from a closed position in which the ventilation flap (7) rests on the frame (2) and closes the aperture (3) in the frame. The method comprises the step of injection-molding the ventilation flap (7) to the frame (2) in an opened position. To this end, the elastomer material is pressed from a free end of the ventilation flap (7) into a common contact area (8) of the ventilation flap (7) with the frame (2).
