    摘要： A slidebolt lock, with slidebolt displacement forces provided by a mechanism outside the lock assembly and acting on the slidebolt, is locked by a blocking member carried by the slidebolt and normally spring biased toward a blocking and locking position. The blocking member engages the lock case and denies the bolt freedom to move in an unlocking direction. The blocking member is forced to a disengaged position by an electromechanical drive, such as a stepper motor driving a cam wheel and cam follower, or a solenoid directly or indirectly acting to force the blocking member to a position within the bolt and disengaging the blocking member from engagement with the lock casing. To simplify the solenoid in one embodiment, upon slidebolt movement toward a withdrawn, unlocked position, the blocking member forms and provides a camming structure to break any residual magnetic seal of the solenoid armature to the solenoid body.

    摘要： A portable sand mold metal treating system having sand cope and sand drag portions, the treating system being attachable to a sand mold metal casting system. The treating system comprises (a) a sand cope portion and a sand drag portion mateable at one or more parting planes, the cope portion containing a tapered entry sprue which extends to the parting plane and contains a slag chamber lying along the parting plane, the drag containing a runner that communicates with the bottom of the slag trap lying along the parting plane, the drag portion containing a sprue well, a reaction chamber having its top lying in the parting plane and overlapping the slag trap to be open thereto, a runner that provides a path for metal flow between the sprue well and one side of the reaction chamber; (b) a mixing channel in the drag portion communicating with an opposite side of the bottom of the slag trap; (c) a tapered secondary sprue extending from the mixing channel to an exterior side of the system to define an outlet port at a level below the reaction chamber; and (d) a flow choke in the secondary sprue for restricting the flow of metal from the mixing channel to ensure adequate mixing and homogenization of the treated metal therein.
