Abstract: Expanding plugs are known which have a threaded bolt with an expanding cone which can be drawn into an expanding sleeve. Expanding plugs of this type can be inserted in a positive-locking manner into drilled holes having an undercut. So that expanding plugs of this type can be fitted without problems, a fastening system is proposed which has a driver, a dog and twist-preventing device which acts on the expanding sleeve of the expanding plug. <IMAGE>
Patent DE-3843163-A1 (DE)
Inventor: MEYER FRIEDHELM DIPL ING
IPC: H02J7/14
Filed: 1988-12-22
Abstract: To ensure an optimal supply of energy to the electrical system from a motor vehicle three-phase alternator, the excitation current is increased above the rated excitation current when the alternator rotates at low speeds, reduced at medium rotational speeds and increased again above the rated excitation current at high rotational speeds. As the temperature in the regulator itself is measured and the regulator is fastened to an alternator component which becomes particularly hot, the moment at which the alternator reaches a maximum permissible temperature can be ascertained in time. The excitation current is then reduced sufficiently for the maximum temperature not to be exceeded.

Title: Protection of motor from overload
Inventor: OGASAWARA HIROMITSU
IPC: H02H7/085
Filed: 1990-10-30
Abstract: Method of protecting an electric motor against overloads, in which the rotational speed of the motor is monitored with respect to a preselected reference value and, if the rotational speed of the motor is lower than the reference value, the voltage applied to the motor is cut off so as to cease the drive to this motor and to protect it against overheating or damage. The rotational speed of the motor is detected in the form of a number of pulses in order to monitor an associated pulse frequency, this pulse frequency being, for example, converted into an output voltage level which constitutes one of the elements for detecting the state of overload of the motor without having recourse to a microcomputer.
