The control device comprises a manually operable switch and a system for controlling the stopping of the motor in a fixed position corresponding to a parking position of a windshield wiper. The system comprises an electrical circuit with at least one sliding contact intended to interact with at least one track having electrically conductive and isolating sectors, a relative rotary movement between the sliding contact and the track being controlled by the motor. One of the elements formed by the sliding contact and the track is intended to be connected to the supply terminal of the motor armature, while the other such element can be grounded during the rotary movement. Said one element is connected to the supply terminal of the motor by means of electrical breaker designed to remain open when the wiper motor is operating normally and close when the manual switch is actuated to control the stopping of the motor.

A reactor for chlorinating rubber has an inlet opening which closely surrounds the rubber material entering the reactor therethrough, and hence any tendency for escape of chlorine is countered by absorption of that chlorine by the entering completely non-chlorinated rubber. The chlorinated rubber emerging from the outlet opening of the chamber is immersed in water before leaving the reactor and hence the outlet is sealed, by the water, against escape of the chlorine treatment gas. The rubber and chlorine displacements through the reactor are counter current to one another.
