Abstract: A micro dispense valve arrangement for accurately dispensing minute quantities of a fluid. The valve arrangement interfaces an enclosed interior region under pressure with an exterior region of less pressure through an orifice opening. The orifice wall is tapered from interior to exterior to bound a frustoconical region constricting toward the exterior to accommodate a magnetizable pellet or ball. The ball is held in its seated position against the orifice wall by permanent magnets imbedded in the wall. An AC coil surrounding the orifice opening acts when energized to cause the ball to move between its seated or closed position and a non-magnetizable screen in its open position. The frequency and duration of applied positive and negative pulses driving the coil act to control the on/off fluid flow duty cycle of the valve.

Abstract: A solenoid driver circuit for a solenoid-operated fluid dispenser in which a valve is operable to dispense a fluid under the control of the solenoid. The driver circuit receives externally applied turn-on and turn-off signals and energizes the solenoid in response to these signals. The driver circuit is responsive to a turn-on signal to couple a pull-in voltage across the solenoid to pull in a solenoid valve armature. The driver circuit is also operable to sense the level of current in the solenoid. When the solenoid current reaches a preset peak current level, the pull-in voltage is removed from the solenoid and replaced by a hold-in voltage. When the hold-in voltage is applied to the solenoid, the driver circuit is operable to control the level of the hold-in voltage in order to maintain a preselected hold-in current in the solenoid. The driver circuit controls the solenoid current so that it makes a gradual transition from the peak solenoid current level to a steady state hold-in current level.

Abstract: An improved ice dispensing mechanism for an ice hopper is characterized by a door or gate which is moved by a variable force to cover and uncover an opening in the hopper. A lever is pivotally mounted at one end and connected at an opposite end with the door, and a solenoid plunger is coupled through a spring with a medial portion of the lever, such that actuation of the solenoid retracts the plunger to extend the spring in one embodiment, and to compress the spring in another, to exert a variable force on the lever to pivot the lever and open the door. Should the door be stuck closed because of ice pressure, by virtue of the spring minimum retraction forces are initially encountered by the plunger when the solenoid is initially energized and the plunger fully extended. This enables the plunger to move into the solenoid, whereupon increased forces are exerted on the plunger by the solenoid, and therefore on the spring, to free the door.

Abstract: A valve arrangement for a liquid flavoring additive under pressure, particularly a non-homogeneous liquid such as high pulp orange juice concentrate, utilizes a fluid pressure to assist in terminating discharge of the liquid flavoring. The fluid pressure may be achieved by utilizing the same compressed air utilized to force the liquid flavoring through the valve structure. Suitable controls, such as a three-way valve, may be utilized to apply the pressurized air to a diaphragm on which a valve member is carried when the valve is to be closed to preclude discharge of the liquid flavoring additive, and to remove the pressure on the diaphragm, such as by venting it to air, when it is desired to permit discharge of the liquid flavoring.

Abstract: In a beverage dispenser of the type having a diluent mixed with a syrup to produce the beverage to be dispensed, provision is made for utilizing a relatively high flow rate. To achieve the relatively high flow rate, a depressurizing system utilizing a vortex chamber is located at the output end of the valve arrangement. The flow path of the diluent through the valve arrangement before the depressurizing system is designed to minimize pressure drops. Diluent leaving the depressurizing system has its velocity decreased by a diffusing structure before being passed for mixing with the syrup. The diffusing system also decreases the swirl imparted to the diluent in the depressurizing system.

Abstract: A pivoting permanent-magnet armature of an electromagnet forming part of a controller to limit the flow of an intravenous solution through a casette to a patient. The electromagnet may have an E-frame with the permanent magnet pivoting between two positions about a point lying on the extension of the electromagnet's middle leg. In one position, one pole of the permanent magent contacts one side leg of the E-frame to open the casette inlet and maintain the outlet in a closed configuration. In the other position, the permanent magnet's other pole contacts the other side of the E-frame to close the inlet, open the outlet, and allow fluid to flow to the patient. A gap should remain between the permanent magnet and the E-frame's middle leg to avoid their grinding together and a concomitant increase of friction due to the presence of resulting particles. Preventing contact between the permanent magnet and the electromagnet's middle leg also avoids the formation of the magnetic shunt between the two at that point.

Abstract: The specification of the present invention discloses an automatic bottle cap that may be applied to an opened receptacle. The valve used in this cap automatically opens when the receptacle is tipped for pouring and closes when the receptacle returns to the upright position. The device uses two permanent magnets positioned such that a net unbalanced force exists between them which is used to open or close the valve. The movement of one magnet within the structure causes the direction of the net unbalanced force to be reversed causing the second magnet and associated valve stem to move and open or close the valve.

Abstract: A ladle for the pouring of a heated molten material such as iron or the like includes a ladle body defining a chamber for holding a heated molten material. There is a bottom pour opening in the chamber and a stopper rod is movable between open and closed positions relative to the pour opening to control the flow of molten material therethrough. An arm is pivotally supported on the side of the ladle and in turn is pivotally connected to the stopper rod. An air cylinder is attached to the arm for causing movement thereof to thereby effect movement of the stopper rod between the described open and closed positions. There is an adjustable rod positioned between the air cylinder causing movement of the pivotal arm and the point of pivotal attachment of the arm to the ladle to thereby control the length of travel of the stopper rod and thus the degree to which the pour opening is exposed by the stopper rod.

Abstract: Valving apparatus designed for use in a remote-controlled beer-dispensing system. The apparatus includes a valve having a plunger selectively movable between opened and closed conditions, and a shiftable lever for controlling the position of the plunger. A pneumatic ram is coupled to the lever through a clevis. Upon supply of a pressurized gas to the ram, the clevis impacts the lever, shifting the latter to produce movement of the plunger from its closed to its opened condition. Upon exhaust of gas from the ram, a spring contained in the ram initiates return movement of the lever to produce movement of the plunger from its opened toward its closed condition, primarily under the influence of the spring. The upstream portion of the plunger has a surface which is exposed to and actable on by fluid flowing through the valve--this surface cooperating with the spring to complete movement of the plunger from its opened toward its closed condition.

Abstract: A dispensing valve mechanism which includes means for automatically maintaning a constant flow of fluid through a flow channel under varying fluid source pressure utilizes a piston movable within a chamber in response to fluid pressure to regulate the available flow area of a single outlet port in the chamber. The piston is sized to permit fluid flow around the periphery of the piston, and may have an axial flow path therethrough to serve as the primary flow path through the valve mechanism. A spring yieldably opposes axial movement of the piston that would tend to decrease the effective area of the chamber outlet port. An adjustment screw is carred in the valve body for adjusting the force exerted by the spring. The valve is particularly suited for use in liquid dispensing apparatus. The valve mechanism is operated by a pivoted arm which includes a projection thereof that engages an electrical switch which causes a solenoid to open the valve.

Abstract: A needle valve nozzle is employed in a hot melt adhesive gun used to apply thermoplastic adhesive. Actuation of a trigger mechanism supplies pressurized gas to a nozzle chamber which urges the nozzle in an outward direction to an open position, the needle remaining stationary during operation of the nozzle. Deactuation of the trigger mechanism stops the flow of pressurized gas to the chamber and a vent allows the pressurized gas to flow from the chamber, permitting a spring-biasing mechanism to return the nozzle to a closed position. Pressure on the adhesive can also be employed to urge the nozzle to an open position.
