Abstract: A housing mounted to the frame of a panic exit device confines a translatable limb, and a pivotable arm. The limb has a lobe which obstructs the arm to prevent its pivoting and, as a consequence, the arm blocks the latchbolt linkage of the device to prevent unlatching. A rod joined to a time-delayed-operative solenoid is coupled to the limb for displacing the limb from arm-pivoting obstruction, to allow the arm to unblock the latchbolt linkage, whereby the latchbolt can unlatch following the time delayed deenergization of the solenoid. Under normal conditions, the solenoid is energized to prohibit immediate unlatching.

Abstract: An ophthalmic instrument support having a flat floor-supported base and a cabinet extends upward from one end of the base, a post projects upward from the cabinet and the upper end of the post pivotally engages one end of a horizontal frame upon which a table is mounted for limited horizontal movement to permit a pair of spaced instruments thereon selectively to be brought into alignment with the eyes of a patient when seated in a vertically adjustable chair with the patient's lap extending beneath the horizontal frame. The post is adjustable vertically a limited amount to dispose the table and instruments thereon at a desired vertical position according to a doctor's eyes when the doctor is seated upon another chair opposite a patient.
