Abstract: The invention relates to miniature electric motors, more particularly to monophase synchronous motors of the type the motor of which includes two pole pieces respectively polarized positively and negatively by the current circulating in an energizing coil, these pole pieces having each N teeth and defining a gap in which is placed a thin, disc-shaped rotor of hard magnetic material. The rotor comprises two annular coaxial portions magnetized with respectively N and N/2 pairs of alternately positive and negative poles.These motors can be adapted to step-by-step working under constant sign pulse feed and are particularly suitable for use in cases where size and power consumption must be reduced to a minimum, such as in electric clockwork movements.

Abstract: This invention relates to a pedestrian protection device for motor vehicles which comprises essentially a hinged member adapted to be raised to an operative position from a normally lower inoperative position on the motor vehicle.More particularly, this hinged member constitutes a kind of transverse beam or barrier having side flanges provided with two series of connecting means associated with a pair of trunnions permitting the rotation of said beam and secured to said side flanges. The second series of connecting means provides an operative connection between the beam and the thrust rod of a cylinder and piston unit having its cylinder pivoted to the vehicle body. The essential purpose of this device is to protect pedestrians against the dangers of running into a car.
