Patent ES-376030-A1 (ES)
Title: Control system for electric vehicles
IPC: B60L3/10
Filed: 1970-01-29
Abstract: Four DC traction motors are serially connected to one another and divided into two groups. Upon the occurrence of a slip, a difference between voltages across the two motor groups is detected and applied to a current regulator along with a current flowing through the motors and a current pattern for normally determining that current. Then a magnitude of current fed back to the motor current is determined and the motor current decreases until the slip terminates. After the slip has terminated, the normal operation is performed.

Title: Compact corona charging device
IPC: G03G15/02
Filed: 1977-01-19
Abstract: A corona discharge device including a corona discharge electrode in contact or closely spaced from a conductive shield electrode, the discharge electrode comprising a conductive wire coated with a relatively thick dielectric material so as to prevent the flow of conduction current therethrough.
