Abstract: A valve is interposed between spaced valve seats of a conduit having end portions communicating with the ends of an internal combustion engine valve cover. The conduit has a vent port located between the valve seats. The valve, which is responsible to inertia and centrifugal forces, is disposed in the conduit between the valve seats for shutting off one or the other ends of said conduit to prevent the loss of upper engine lubricants from the valve cover during rapid acceleration, deceleration or sharp cornering of a vehicle driven by the engine.

Abstract: A valved stopper insertable into the inlet passage of a urine bottle permits only unidirectional flow into the bottle to prevent accidental spillage. The stopper has a generally tubular body which retains a valve member. The valve member is free to move in the tube under gravitational influence. When the urine bottle is tilted or inverted the valve member moves toward the inlet opening and sealingly engages the inner surface of the tube to block off flow from the bottle.

Abstract: An interceptor apparatus actuated by seismic and other vibrations comprising a substantially vertically movable rod, a weight capable of engagement with the rod and a plurality of pivotable support arms supporting the weight within a housing and held in a mechanically balanced state in entirety. When the apparatus undergoes seismic or other vibrations, the mechanical balance is lost, whereupon the weight is released from the support arms and is allowed to fall together with the vertically movable rod due to the gravitational forces, thereby effecting the switching of a related fluid circuit or electric circuit.

Abstract: An improved carburetor for vehicle engines of the down draft type having a suction duct connected to an intake manifold, a float chamber storing a predetermined constant quantity of engine fuel and arranged on one side of the suction duct in the transverse direction of a vehicle equipped with the carburetor, and a vertically extending fuel passage connected at one end to the float chamber and at the other end to a main fuel nozzle opening into the suction duct, the carburetor being capable of holding the fuel contained in the fuel passage at all times at a predetermined constant level for highly stabilized fuel supply to the engine irrespective of lateral or longitudinal inclinations of the fuel surface in the float chamber occurring under conditions of acceleration, deceleration or turning of the vehicle.

Abstract: A liquid dispensing nozzle of the automatic shut-off type has the trigger, which holds the valve actuating means in an open position, or its retaining means formed to flex when subjected to a force beyond that exerted by the valve actuating means when it is in any set flow position so that the trigger is automatically released from its retaining means if the nozzle should be accidentally removed from the fill pipe, for example.

Abstract: Vibration sensing and responding apparatus which includes a concave spherical surface and a ball disposed on said surface. Spring loaded means extends through said surface and is retained in position by said ball. Should the ball be displaced by horizontal vibration of the surface or be displaced by a mechanism responding to vertical vibration, the spring loaded means will move upwardly and in so doing actuate a device coupled thereto.

Abstract: A tilt responsive shut-off valve in a fuel line of a motor vehicle to shut-off fuel flow from a supply tank to a carburetor when the vehicle is upset in any direction. The valve includes an inlet passage, shut-off passage and outlet passage connected between the valve inlet and valve outlet. The shut-off passage includes dual ball members cooperating with a valve seat and each other to shut off fuel flow when the vehicle is upset beyond a predetermined amount. Under normal operating conditions, a sealing ball, biased toward a closed position, is held away from its associated valve seat face by a counterbiasing ball thereby permitting fuel flow through the valve.

Abstract: An outlet pipe passes through the wall of an inlet pipe and communicates therewith. At the intersection of the two pipes, a flat valve seat is formed. A spring-loaded valve presses down against the valve seat to isolate the two pipes when unlocked, leaving the seat unobstructed and the pipes in communication when in a locked position. A catch normally supports the valve against the pressure of the spring, but pivots out of the way to allow the valve to close against the seat, in response to an electrical signal obtained from a battery placed in series with a mercury switch. A solenoid, actuated by the closing of the switch, moves the catch to its unlocked position.

Abstract: An automotive fuel system which has a fuel tank, a fuel pump, a fuel metering device for metering fuel flow to an associated fuel-consuming engine, and a fuel reservoir (such as, for example, a carburetor fuel bowl), has a valving assembly interposed generally between the outlet of the fuel pump and the fuel reservoir with such assembly being responsive to, for example, the associated vehicle experiencing a crash impact or a roll-over condition whereupon such valving assembly becomes effective to prevent the further flow of fuel from the fuel pump into the fuel reservoir.

Abstract: A roll over valve construction having a housing provided with an inlet and an outlet separated by a valve seat. A pair of balls are carried by the housing so that one thereof can move to close the valve seat when the valve construction is rotated from its normal position to a certain other rotational position thereof, the pair of balls normally being held away from the valve seat by gravity when the valve construction is between the normal position thereof and the certain position thereof. A larger ball member is carried by the housing for preventing the first pair of balls from moving to close the valve seat when the valve construction is between the normal position and the certain position thereof even though the valve construction is being subjected to shocks, impacts, bouncing, etc. that would normally cause one of the pair of balls to move to close the valve seat.

Abstract: A compact vehicle crash cushion assembly including, within a single receptacle, a source of pressurized fluid, an inertia-type actuator for releasing fluid from the source and an inflatable bag. The inertia member is held in a cocked position by ball detents. Movement of the member starts withdrawal of a sear pin from engagement with a spring-biased hammer which results in a special cutting member piercing a diaphragm in the source of pressurized fluid causing the fluid to be released to inflate the bag.

Abstract: An arrangement for the switching on-and-off of a pressurized medium flow and, more particularly a pressurized medium flow which is conducted to a valve through a pressure medium conduit, and then further conducted from there to a withdrawing or extracting location. The valve is supported on a holder so as to be supportable thereon between two end positions, and is so constructed as to block the pressurized medium flow in one of the end positions and to release it in the other end position, and including actuating means which are coupled with the valve which, upon actuation, will displace the valve in a context of positional change thereof.

Abstract: A gasoline powered motor vehicle is provided with a tilt rsponsive shut-off valve in its fuel line to shut-off gasoline flow from the fuel tank to the carburetor when the vehicle is tilted. The valve includes a tee shaped shut-off passage having a first branch and a second branch connected in series between the valve inlet and the valve outlet. A tilt responsive ball valve in the first branch shuts off gasoline flow when the vehicle is tilted in one direction, and another tilt responsive ball valve in the second branch shuts off fluid flow when the vehicle is tilted in the other direction. Each of the ball valves includes a ball cavity for storing the ball when the vehicle is in an upright position and a reduced diameter restrictive passage leading from the ball cavity to retain the ball in a deactuated position under normal operating conditions by providing a combination mechanical and fluid barrier.

Abstract: An acceleration responsive device usable as a shut-off valve for a fluid conduit having a pair of reactant masses which are loosely interlocked together, the masses mounted within a housing. Upon the housing receiving a shock force of predetermined magnitude, the masses are caused to move from an in-line interlocked position to a misaligned interlocked position. The masses are connected to a latching means which when in the misaligned position is activated to move an actuation means to close the fluid conduit.

Abstract: A hydraulic valving mechanism for controlling an object in a normally level position such that upon a shifting of the same from level an actuating mechanism is driven to return the object to the desired level, such valving mechanism including a valve housing with control ports therein with a gravity responsive member therein to open and close selected ones of the ports depending upon the direction the same is shifted from level with the ports being interconnected to a main control valve for shifting of the same to direct fluid to the proper side of the actuating mechanism to return the object to its normal, level position.

Abstract: A fluid flow shut-off device has a number of valves which upon lateral tilting movement of the device selectively move to block flow, regardless of the direction of tilting movement.
