Digital indicating installation for motor vehicles

A method and apparatus for effecting an automated exchange of a tool in hobbing machines. At least a pair of gripping devices are mounted on a shaft for relative sliding movement therealong and for selective locking engagement with the shaft so that a rotation of the shaft will effect a rotary movement of a selected one of the gripping devices. The rotary movement of the selected gripping device is between a storage position and a working position. The gripping device is capable of holding a tool which is to be exchanged for a worn out tool. The other gripping device is generally empty and is first moved into the working position to extract the worn out tool from the milling spindle. Thereafter, the gripping devices are shifted to bring the appropriate device having a new tool therein into a position so that it can be rotated with the shaft to bring the new tool into the working position and inserted onto the milling spindle.

In order to test at least one of the operating and capacitating conditions of an automotive vehicle, plural parallel circuits are included in a test circuit associated with sensors for each condition to be tested. These parallel circuits contain at least one pilot lamp and at least one switching unit. The switching unit may have simple switch contacts or may contain an electronic switching element. During normal operating conditions, the switching units are closed to provide a conductive path therethrough. During non-normal operating conditions and/or capacity conditions, the switching units open. For testing any condition, an individual test switch, which energizes each pilot lamp in the plural parallel circuits, is connected in series with the switching contacts and/or the conductive electronic switching elements of the switch units and with the pilot lamps in the plural circuits.
