Enovid was first marketed in the U.S. in 1957 not for birth control but to help with disturbances of menstruation (see Enovid brochure above). The U.S. Food & Drug Administration mandated a warning on the label that it would prevent ovulation. And women quickly learned that this pill would prevent pregnancy.
A solenoid valve is an electromechanically operated valve. The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports.olenoid valves are also characterized by how they operate. A small solenoid can generate a limited force. If that force is sufficient to open and close the valve, then a direct acting solenoid valve is possible.
