Bernardus H A Goddijn: Synchronous motor. U S Philips Corporation, Robert S Smith, June 3, 1980: US04206374 (68 worldwide citation)

A synchronous motor, in particular a stepping motor, with two coaxial stator sections which are each provided with a ring coil and with two circular systems of teeth, which are shifted by half a tooth pitch relative to each other. The two stator sections are shifted by a quarter tooth pitch relative ...

Bernardus H A Goddijn deceased, by Friedrich J de Haan administrator: Mains-voltage discrimination device. U S Philips Corporation, Robert T Mayer, Bernard Franzblau, October 8, 1985: US04546305 (8 worldwide citation)

A supply-voltage discrimination device for adapting a load (8) to a lower or higher alternating-voltage range includes a voltage-dependent resistor (1) thermally coupled to a PTC-resistor (2) and electrically connected in series with said voltage-dependent resistor. The resistors are chosen so that ...
