Abstract: A dashpot solenoid is provided having a thin-walled well with a support ring around an accurately sized and shaped slightly reduced mouth portion and an adjustable air metering orifice at the bottom or opposite end. A plunger coated with a polyfluoro hydrocarbon is sized and shaped to fit within the well such that the clearance between the plunger and the mouth portion of the well provide a functionally airtight sliding fit. In operation the plunger is drawn into the well and air captured therein is permitted to escape through the adjustable metering orifice at a rate which damps the plunger motion.

Abstract: A bistable electromagnetic actuator has an armature maintained in one stable position magnetically, by means of a permanent magnet, and in a second stable position by means of a spring. Either position may be assumed by energization of a coil with current of the appropriate polarity or by application of mechanical force. A magnetic shunt maintains flux through the permanent magnet during energization of the coil.
