    • A MOTOR VEHICLE INCLUDES A TRANSVERSELY EXTENDING HINGED COWL PANEL ADJACENT THE LOWER EDGE OF THE WINDSHIELD FOR CONCEALING THEREBELOW THE WINDSHIELD WIPER ARMS AND BLADES WHEN PARKED. THE HINGED COVER OR COWL PANEL IS MOVABLE FROM A CLOSED POSITION WHEN THE WIPER ARE PARKED TO AN OPEN POSITION WHEN THE WIPERS ARE OPERATING. A FLUID PRESSURE WINDSHIELD WIPER MOTOR OSCILLATES THE WIPER ARMS AND BLADES THROUGH A LINKAGE TRANSMISSION. THE MOTOR INCLUDES AN AUXILLARY LINEARLY RECIPROCATING DRIVE SHAFT FOR MOVING THE COWL TO OPEN POSITION WHEN THE WIPER MOTOR IS STARTED BEFORE THE ARMS AND BLADES MOVE OUT OF PARKED POSITION AND TO CLOSED POSITION WITH THE WIPER MOTOR IS SWITCHED OFF FOLLOWING MOVEMENT OF THE WIPER ARMS AND BLADES TO A DEPRESSED PARK POSITION. THE LINERALY RECIPROCATING DRIVE SHAFT IS COUPLED TO THE HINGED COWL PANEL THROUGHT A RELEASABLE COUPLING ASSEMBLY WHICH CAN BE UNCOUPLED TO PERMIT MANUAL MOVEMENT OF THE COWL PANEL TO AN EXTREME OPEN DETENT POSITION FOR ACCESS TO THE EQUIPEMENT STOWED THEREBELOW. THE COUPLING ASSEMBLY IS PROVIDED WITH AN INTERMDIATE DETENT POSITION FOR RETURNING THE COWL TO A POSITION TO PERMIT WIPEROPERATION IN CASE OF FAILURE OF THE COWL RETRACTING MECHANISM.

    • A SYSTEM FOR STORING VOLATILE MATERIALS AND DISPOSING OF EXCESS VAPORS AND OVERFLOW INCLUDES A RESERVOIR WHICH MAY BE, FOR EXAMPLE, A GASOLINE TANK FOR AN AUTOBILE, AND FILTERING APPARATUS CONNECTED TO THE RESERVOIR THROUGH A MULTIDIRECTIONAL VALVE ASSEMBLY EMPLOYING A PRESSURE DIFFERENTIAL ACTUATED APERTURED DIPHRAGM HAVING A LIP CIRCUMSCRIBING THE APERTURE WHICH SERVES AS A VALVE ELEMENT SLIDABLE ON A TUBULAR VALVE SEAT. THE VALVE IS SPRING BIASED TO A NEUTRAL POSITION SEALING THE TANK OUTLET AND REMAINS IN THAT POSITION WHEN THE PRESSURE IN THE STORAGE TANK IS SUCH THAT THE TANK CAN CONTAIN THE VAPORS. WHEN AMBIENT CONDITIONS ARE SUCH AS TO CAUSE EXPANSION OF THE FLUID AND THE VAPOR THE DIAPHRAGM AND VALVE MOVE TO AN OPEN POSITION FOR PERMITTING THE VAPOR OR OVERFLOW FLUID TO FLOW THROUGH FILTERING AND DISPOSABLE APPARATUS. IF THE FILTER OR ANY OF THE LINES LEADING THEREFROM BECOME CLOGGED, OR IF PRESSURE INCREASES IN THE TANK AT A RATE WHICH CAUSES AN INCREASE OF PRESSURE ON THE DIAPHRAGM, A SECOND APERTURE IS OPENED TO PERMIT V ENTING TO ATMOSPHERE. IF SUBATMOSPHERIC PRESSURE CONDITIONS EXIST IN THE RESERVOIR THE DIAPHRAGM IS DRAWN TO A POSITION OVERLYING CONDUITS ON THE EXTERNAL WALL OF THE TUBLAR VALVE SEAT TO PERMIT VENTING TO THE ATMOSPHERE FOR PRESSURE EQUALIZATION.
