Abstract: Live loaded valve stem packing wherein grafoil packing is molded into a metal cap that prevents extrusion of the packing, and has live loading built into the metal cap. This metal cap can be conventional flat spring materials (17-7PH S.S. or 302 S.S.) or a Shape Memory Alloy (commonly known as SMA materials, e.g. Ni—Ti (Nickel-Titanium alloy) or Fe—Si—Mn (Iron-Silicon-Manganese alloy). The cap is designed with a singular hump, entirely along its top surface. On this hump there are two slots through the hump, 180 degrees apart, for ease of removing the packing. Upon assembly of the packing box, the hump is elastically flattened out due to axial loading through the fasteners. As the packing consolidates during service (optionally if the cap is SMA, during temperature increases) the hump deflects to maintain a relatively constant or enhanced axial load on the packing to enhance sealing, even during a fire.

Abstract: A fuel dispensing system compensates for varying fuel source flow rate requirements based on fuel dispenser feedback signals. A pumping system pumps fuel from one or more fuel sources to one or more fuel dispensers through associated conduits. When actively dispensing fuel, each fuel dispenser monitors its actual fuel discharge rate and adjusts an integral flow control device to maintain a nominal fuel discharge rate. When an active fuel dispenser fails to achieve its nominal fuel discharge rate, it indicates this condition to the pumping system via its dispenser feedback signal. In response, the pumping system increases its pumping rate until the fuel dispenser achieves its nominal fuel discharge rate. Other active fuel dispensers adjust their flow control devices as needed to maintain their nominal fuel discharge rate in response to the adjusted pumping rate.

Abstract: A hose coupling apparatus for removably coupling a hose to a discharge opening of a spray unit includes an elongate hose retainer having a plug end and a stem end. The hose retainer defines a longitudinal fluid passageway extending therethrough from the plug end to the stem end. The plug end is configured for being received within the discharge opening of the spray unit. The stem end is configured for being coupled to the hose. At least one locking tab is disposed intermediate the plug end and the stem end. Each of the at least one locking tab is configured for being disposed within a corresponding slot defined by a neck which surrounds the discharge opening of the spray unit, thereby precluding rotation of the hose retainer relative to the neck. A hose nut defines a hose bore therethrough. The hose bore is configured for receiving the hose such that the hose nut is slidable over the hose.

Abstract: The piezoelectric element laminate 20 which expands due to application of a voltage is disposed between a diaphragm valve 11 applied with elastic force in a valve opening direction and a valve spring mechanism 25, a distortion amount a of the piezoelectric element laminate 20 in expansion is set to be larger than an opening/closing stroke b of the diaphragm valve 11, and a spring seat 28 separates from a second stopper 30 due to a difference c between the distortion amount a and the opening/closing stroke b. As a result, when the piezoelectric element laminate 20 expands to seat the diaphragm valve 11 on a valve seat 10, the valve spring 29 is compressed and repulsing force of the valve spring 29 acts on the diaphragm valve 11 through the piezoelectric element laminate 20 and the diaphragm valve 11 is pressed against the valve seat 10 by the repulsing force.

Abstract: A dispensing apparatus for dispensing a product from a container under pressure of a propellant by means of a composite piston (138). The apparatus has a valve (104) operated by means of an actuator (108) and a lever (166). The actuator co-operates with the valve and lever by means of a screw thread arrangement (110), such that turning actuator relative to the lever varies the flow rate of product out of the apparatus. The valve is a hollow cylindrical tube (104) which is open at one end and closed at the second end, either permanently or by means of a flap valve (112) which allows insertion of the product. A number of ports (116) are arranged around the circumference of the tube (104) adjacent to the second end to allow product to flow through the valve when the lever is operated.

Abstract: A two-component resin or adhesive dispensing system comprises a pair of activator and resin or adhesive metering pumps and a drive motor. The drive motor is a hydraulic drive motor driven by means of a hydraulic pump which, in turn, is driven by means of an air motor coupled thereto. The metering pumps are separately and independently driven by the hydraulic drive motor through means of sprocket and chain drive systems, and the metering pumps are mounted upon adjustably movable mounting brackets such that their relative disposition may be readily altered so as to accommodate different sized sprocket members which will then alter the drive output of the metering pumps in order to change the ratio of the amount of activator material dispensed with respect to the amount of resin or adhesive material dispensed.

The actuator has a top surface and a periphery. The actuator defines an outlet, an inlet cavity, and an internal discharge passage extending between the outlet and the inlet cavity. The inlet cavity has a configuration and size for sealingly receiving the end of the discharge tube in a friction-fit engagement. A shell surrounds the periphery of the actuator. The shell has an open top providing access to the top surface of the actuator and has a notch adjacent the outlet to permit the discharge of product from the outlet as the actuator is depressed relative to the shell. A plurality of tabs each extends from the actuator to the shell. Each tab is connected to the shell with a frangible web to hold the actuator at an initial, as-molded position relative to the shell.

Abstract: A method and apparatus for dispensing multi-component foamable fluid plastic materials such as polyurethane foams. The apparatus includes a mixing chamber defined by an axial passage in a support body structure. The mixing chamber receives reactant fluids for mixing then allows the fluids to exit through an opening at one end of the axial passage. Two fluid inlet openings in a wall of the axial passage admit reactant fluid into the mixing chamber. Two mixing chamber fluid inlets formed in the support body structure communicate reactant fluid sources with the mixing chamber through the inlet openings. When retracted, a valve needle in the axial passage exposes the inlet openings to admit reactant fluids into the mixing chamber. When advanced, the needle closes off the inlet openings and pushes the mixed fluids from the mixing chamber. The valve needle includes three parallel helical grooves that help purge the mixing chamber of unreacted and reacted fluids.

Abstract: A mixing valve assembly is provided for a container structure. The mixing valve assembly includes a valve stem having an inlet within the container structure and an outlet external of the container structure. The valve stem is movable between a first depressed position wherein the composition is retained in the container structure and a second position wherein the composition exits the container structure through the outlet of the valve stem. A generally concave biasing structure extends from the valve stem and urges the valve stem toward the first position.

Abstract: An actuator for aerosol spray cans utilizing a toe, as a pivot point, to engage the inside recess on the cup rim bead of the can (the bead which surrounds the spray nozzle) and a heel portion that extends against the valve stem mount. The body and handle of the actuator extend from the toe and heel upward and over the spray nozzle of the can with the handle being positioned approximately perpendicular to the direction of the spray exhaust of the can. Spray action is initiated by depressing the handle of the actuator with forefinger or thumb, causing the toe of the actuator to act as a pivot in the inside recess of the cup rim bead and the heel to slide against the valve stem mount. A protrusion on the body of the actuator depresses the aerosol spray nozzle creating a spray exhaust. The end of the actuator handle is formed to insert into the spray can cap and is used as a pry for removing the cap from the can.
