Abstract: An aerosol tilt valve has an integrated molded hollow stem shaft and molded conical stem cup. An upper outer circumferential edge of the stem cup normally fully seals, except when the valve is tilted, against a gasket surrounding the stem shaft. The outer lower wall of the stem shaft and the inner wall of the stem cup define an annular space. At least one molded metering orifice below the upper edge of the stem cup extends from the annular space through the stem shaft. The stem shaft is molded with a molded annular recess about the lower shaft end and with the at least one molded metering orifice. The molded stem shaft is inserted in a mold cavity. A lower portion of an annular shield blocks the metering orifice, and together with the mold cavity and lower part of the stem shaft, defines the stem cup shape. The stem cup is molded having an annular projection extending into the annular recess to form a strong and fully integrated stem cup and stem shaft functioning essentially as one piece.

Abstract: An aerosol valve assembly, lacking a return spring and dip tube, has a valve housing and a valve body with a lower portion, an intermediate portion and a valve stem. A gasket in a stem groove seals one or more orifice openings into the valve stem except on valve actuation. The valve housing has a lower wall with a central opening for the valve body lower portion to enter to stabilize the vertically acting valve; and, a plurality of product delivery openings positioned about the central opening. A stroke-limiting surface on the valve body prevents the gasket from completely escaping the stem groove on valve actuation. When valve actuation ceases, the valve is returned to closed position by the gasket acting against the stem groove, and the product acting against the valve body bottom portion and the lower surface of the valve body intermediate portion.

Abstract: A method of forming a hole to a final specified dimension in a fiber reinforced wheel for a motor vehicle, and a fiber reinforced wheel with such a hole. Stud mounting holes, or a hub hole or a valve hole, are drilled through the wheel to an internal dimension larger than the final specified dimension, to sever and expose fiber ends in the wheel surrounding the hole. Thermoset resin with coupling and curing agents is applied to the hole internal surfaces by brushing or spraying, and is thereafter cured, and atomically and mechanically bonded to the internal hole surfaces with exposed fiber ends to form a thin smooth permanent protective layer on the hole internal surfaces defining the hole at final specified dimension. The hole may have frustoconical, spherical radius, and/or cylindrical portions.

Abstract: A dual receptacle aerosol sprayer with a thin, flexible plastic outer receptacle for product and a substantially rigid inner receptacle for propellant seated within the outer receptacle. A closure closes the inner receptacle and contains a valve assembly. Primary propellant and secondary product valves in the valve assembly control flow from the inner and outer receptacles up propellant and product valve stem bores into an actuator having an aspirating nozzle insert with a Venturi constriction. A conduit extends from the valve assembly through the inner receptacle and into the outer receptacle. To avoid propellant overloading and rupture of the outer receptacle, a one-way tertiary valve downstream of the secondary product valve closes on clogging of the actuator discharge outlet to prevent, during actuation, misdirected propellant flow from the actuator and through the stem product bore and the secondary product valve, from entering the outer product-containing receptacle.
