Abstract: An atomizing pump for dispensing liquids from a container which has a low profile and is non-throttling. The pump comprises a body, a spring biased piston, a lower valve openable and closable by both pressure in the pump body and by frictional interengagement with the pump piston with an extending upper end of the lower valve, and an upper valve that frictionally and sealingly fits in a lower chamber in the piston, but which can be moved against a spring force and the friction force when pressure in the pump reaches a critical limit, so that the upper valve moves into a larger upper chamber so that liquid can escape from the pump body. The upper valve preferably has an extending stem that contacts the extending upper end of the lower valve during the terminal portion of a downward stroke of the piston and an initial portion of an upward stroke of the piston so that the upper valve can be held open.

Abstract: An apparatus and a method for dispensing hot melt adhesive or other materials. The apparatus includes a container and an outlet. The container has a first material (the material to be dispensed) disposed therein, which changes from a solid state or a state of high viscosity to a state of low viscosity when heated above a predetermined temperature. The container also has a second material disposed therein, which is adapted to be heated above a predetermined temperature when subjected to microwaves for at least a predetermined period of time. The second material is in a heat transfer relationship with the first material. While the dispenser is being subjected to microwaves, the second material converts the microwave energy into heat and transfers the heat to the first material. The first material then changes to a state of low viscosity and can be dispensed from the container through the outlet.

Abstract: A caulking device uses a long flexible tube (40) to connect a belt-worn cartridge housing (50), which accepts standard caulking cartridges, to a hand-held gun (20). The housing contains an electric motor and drive mechanism to force a piston into the cartridge. Caulking is pushed from the cartridge into the flexible tube, through the tube to the gun. The gun contains a trigger-actuated valve which allows caulking to pass into a disposable nozzle from which it is dispensed to the workpiece. A pressure sensor in the housing activates a switching circuit to maintain pressure in the tube.

Abstract: Material dispensing apparatus includes an elongate hopper having a flexible apertured bottom, and an agitator bar mounted for rotation within the hopper having a plurality of circumferentially spaced longitudinally extending rods supported on a rotating stabilizer shaft for material dispensing contact with the apertured bottom. The contact between the longitudinally extending rods and the flexible apertured bottom moves the bottom of the hopper in both an up-and-down and side-to-side direction such that the holes in the bottom change shape and material contained within the hopper is both vibrated and pushed through the apertures in the bottom of the hopper onto a product underlying the hopper. The apparatus is designed to dispense moist pre-sized powder-like materials that tend to agglomerate and adhere together.

In various embodiments of the invention the shrink induced dispenser is used to dispense lubricants, inks, additives, and medications. In heat activated embodiments the inventiuon is capable of integral temperature responsive automatic flow control.

Abstract: A mechanically pressurized system for dispensing a product, including a cap that houses a piston, an actuator attached to the cap so as to form a dispensing head assembly, and an expandable reservoir that is mechanically charged by the piston and dispensing head to hold a product for discharge through the dispensing head. The dispensing system is able to produce an aerosol spray without a chemical propellant.

Abstract: A dispenser for liquids, e.g., ophthalmic liquids, is provided with a restricted up and down movable top that locks in both open and closed positions and that lifts to uncover an aperture and to expose a recessed dispensing tip which is always maintained below the plane of the aperture and that lowers to cover the aperture and conceal the dispensing tip.

Abstract: A manually operated continuous aerosol sprayer which eliminates the need for the use of potentially environmentally dangerous substances. A container is provided to hold a liquid and an inflatable bladder is located inside the liquid container. A pump is provided for filling the bladder with air from the outside atmosphere. The open end of the inflatable bladder is attached to the pump so that it may be readily filled by the pump with the remainder of the inflatable bladder extending into the liquid container. When the bladder is inflated it expands causing the liquid in the container to become pressurized. The pressure from the inflation of the bladder causes the air and the liquid to be forced into a spray chamber where they mix and are forced out a spray nozle as an aerosol spray.

Each tube 2, 35 is surrounded by and integral with a bellows 6, 38 of which the inside is connected permanently to the outside atmosphere, the top end of the bellows being fixed either to housing 3 or to the lower end of the first tube 2. The second tube 35 with its intake flap 32a is controlled outside of the housing 3 by means of the piston 36 of a jack.

Abstract: The dispensing cartridge comprises a storage cylinder and a dispensing piston whose bottom surface is progressively recessed from the piston edge towards an aeration bore. An overflow chamber is disposed around said aeration bore, overflow slots being provided in the wall which forms said aeration bore. Said aeration bore is sealed by a closure whose peg portion extends into said bore and whose head is provided with a surrounding bead which snaps into a corresponding annular groove in the outer wall of said overflow chamber. Such a cartridge prevents a disturbing effect of the material flowing out when the dispensing piston is inserted, and during the aeration procedure.

Abstract: A discharge apparatus for use in bins or hoppers in which a pluraity of rolls are disposed in a lower portion of the bin, and are so arranged to inhibit gravitational flow of material between the spaces defined by adjacent rolls. The rolls include knobs, plates, or the like extending outwardly therefrom, and the rolls may be arranged in a single row, or in multiple rows. When the rolls are rotated, material above the rolls is permitted to flow between the rolls and out of the bin or hopper. The rolls may be horizontal, or inclined, and may be variously shaped, including cylindrical, conical, or other geometrically complimentary shapes.

The hand positioner is for providing pressure contact with the dorsal web of the hand of a user between the thumb and the index finger when the user grips the container and pulls the trigger so that the container and the hand and wrist of a user are held in substantial alignment during spraying operations. The hand positioner includes a bottom wall that is in pressure contact with the dorsal web of the hand of the user during spraying operations.

Abstract: A container-closure assembly comprises a container molded of relatively soft plastic and a closure cap molded of relatively hard plastic and having a top wall and a continuous side wall. Threads are formed on both the finish of the container and inward on the side wall of the cap. The threads on the cap comprise three threaded segments spaced about the inner circumference of the side wall. The segments include an inward upwardly sloping rib, the upper surface of which is formed with a plurality of wedge-shaped teeth. In use, the closure is screwed on to the top of the container finish and the teeth dig onto the underside of the threads on the finish causing the instantaneous elastic deformation of the plastic of the finish to anchor the cap against removal.

Abstract: The invention relates to creating an optical illusion of fluid or water in a display device which shows a solid water stream with undulations that rises, levitates or falls slowly. The illusion can be viewed under certain circumstances in ordinary room lighting. Also, the solid water stream with undulations can simultaneously transform into a set of rising, levitating or falling water droplets. The entire illusion may be examined and even touched by the audience.
