Abstract: The present invention relates to an adjusting apparatus having an optical aimer that includes a reflector for adjusting parts of a motor vehicle, in particular distance warning radar, headlights, or an axle; having an emitting device that emits a collimated beam; and having a vertical adjusting device for orienting the reflector at a certain angle to a floor of a measuring station forming the contact plane of the vehicle.

Abstract: The present invention relates to an adjusting apparatus having an optical aimer (2) that includes a reflector (2.1) for adjusting parts of a motor vehicle, in particular distance warning radar, headlights, or an axle; having an emitting device (3) that emits a collimated beam (3.4); and having a vertical adjusting device (1) for orienting the reflector (2.1) at a certain angle (&bgr;) to a floor (5) of a measuring station forming the contact plane of the vehicle. An exact vertical alignment or orientation at a certain tilt angle to the floor of the measuring station is achieved by simple measures, in that the emitting device (3) is positioned in a vehicle region remote from the aimer (2), at a specific, defined level (h) of the vehicle above the measuring-station floor (5) and may be adjusted for emitting the beam (3.

Abstract: The device for testing an ignition system of a combustion engine comprises an adjustable load connected in the primary winding of the ignition coil by means of which the stored energy is so long reduced until due to the deficient energy the first ignition slip of the fuel-air-mixture occurs. This reduced energy is compared with the nominal or normal energy required for proper operation of the ignition system and the difference between the two values determines a measure for ignition energy reserve and consequently a measure for the condition of the whole ignition system. The energy reserve is measured selectively always for a part of the ignition system, that means for a cylinder of the engine. For this purpose a selective switch is employed using a scaler fed by pulses derived from the contact breaker and synchronized by a pulse from the part of the cylinder under test produce an output pulse which connects the loading member to the primary winding of the ignition coil.
