摘要： A hot melt adhesive dispensing system that includes a hand held gun and a molten adhesive source, the gun and the source being selectively connectable one with the other in a novel manner to permit charging and recharging of the gun with molten adhesive from the molten adhesive source. The hand gun includes novel charge valve structure adapted to interconnect with novel feed valve structure mounted on the hot melt adhesive source so as to accomplish transfer of a hot melt adhesive charge in molten form, from the source to the gun storage chamber. The adhesive is pressurized within the gun's storage chamber by a novel pressure device at least partially incorporated within the storage chamber, thereby providing the motive force to cause discharge of molten adhesive from the gun's nozzle in response to manual activation of the gun's trigger.

摘要： A hot melt adhesive foam pump system having a first stage pump that meters molten hot melt adhesive into a second stage pump, which in turn mixes gas under pressure into the adhesive so that the gas is driven into solution with the adhesive at an adjustably controllable ratio. The pump is insensitive to changes in adhesive viscosity and pump speed, and provides uniformity of foam density and output flow rate when the adhesive is ejected from a dispenser connected to the pump.

摘要： A gear pump for dispersing a gas into a liquid is provided with mixing means for improving the uniformity of the dispersion. In preferred form, the mixing means comprises a series of fixed, shallow, blind cavities that open to the pumping cavity between the liquid inlet and the outlet, and which are positioned to be "wiped" by the gear teeth as the gears rotate. The alternate connection and disconnection of the intertooth spaces to these cavities as the gears rotate establishes motion or turbulence of the gas/liquid mixture within the intertooth spaces, and surprisingly improves uniformity of the dispersion.

摘要： A hot melt adhesive dispensing system including a hot melt adhesive dispenser, a hot melt adhesive tank, and a hose for coupling hot melt adhesive from the tank to the dispenser. The dispenser, the tank and the hose are heated by electrical heaters to maintain the adhesive in a suitable molten condition for dispensing and for flowing from the tank to the dispenser. When the hot melt adhesive system is first energized, the hose and tank heaters are coupled to a source of electrical power and the temperature at either the tank or the hose is sensed. When the sensed temperature reaches a suitable preselected level, the dispenser heater is then energized by coupling the heater to a source of electrical power. In this way, as the adhesive in the dispenser is heated from a solid to a molten form, it is free to expand into the hose, with the adhesive in the hose adjacent the dispenser having already been heated to a molten state.

摘要： A novel handle structure, and a novel heat exchanger structure, for a hand-held adhesive gun of the type adapted to discharge a heated thermoplastic adhesive through a discharge valve located in the gun's barrel. In preferred form, the novel handle structure is positioned at the aft end of the gun's barrel, and has a longitudinal axis extending rearwardly of the gun's barrel and located at an acute angle relative to the longitudinal axis of the gun's barrel. The gun's handle is positionable about the gun barrel's longitudinal axis between at least two operating locations, one being positioned 180.degree. from the other. A gun control switch is mounted interiorly of the handle, the switch being mechanically operated by the gun's trigger. At least two ports are provided in the handle, one at the foot of the handle and the other adjacent the gun's barrel, the power cord that interconnects with the gun control switch being receivable into the handle through either port depending on the use orientation of the handle. Also in preferred form, the novel heat exchanger includes a heat exchanger core fixed in location within a heater body's bore. The heat exchanger core has spiral threads on the outer surface thereof, and the bore's surface has spiral threads thereon, too. The heat exchanger core's threads are sized relative to the inlet bore's threads such that the core can be threaded into the bore, and such that the threads cooperate to define a spiral path about the core through the bore from one end to the other, thereby defining a spiral heat exchange path through the gun's heater body. This novel heat exchanger is particularly adapted to elevate the temperature of the molten adhesive, just prior to dispensing it, above that temperature level at which the molten adhesive is supplied to the hand gun.

摘要： A device for sensing and controlling liquid level in a reservoir container. The device includes a sensing element in the form of a displacer which enters the liquid through the surface and displaces a predetermined volume. The displacer is located in a surge tank into which the liquid is initially fed and from which it is supplied to the reservoir. The displacer is mounted on an arm of a lever, the displacer being counterbalanced to respond to a liquid level in the surge tank. The lever carries a switch actuating mechanism which is moved in response to a change in the liquid level in the surge tank and which controls actuation of a single acting piston pump air motor to supply liquid to the surge tank.

摘要： An apparatus for dispensing adhesive in an elongated strand or fiber in a controlled, spiral pattern upon a substrate comprises a dispensing device having a nozzle formed with an adhesive delivery passageway and an air delivery passageway both of which terminate at the base of the nozzle. A nozzle attachment in the form of an annular plate is mounted to the base of the nozzle by a cap. The annular plate is formed with a throughbore which receives hot melt adhesive from the adhesive delivery passageway and ejects an adhesive bead through a nozzle tip formed on the outer side of the plate opposite the nozzle. An annular groove formed in the outer side of the plate facilitates drilling of air jet bores therein at an angle relative to the throughbore and adhesive bead ejected therefrom. The air jet bores receive pressurized air from the air delivery passageway in the nozzle and direct jets of pressurized air substantially tangent to the adhesive bead to form an elongated adhesive fiber and to impart a spiral motion to the elongated adhesive fiber so that a compact, spiral pattern is formed for deposition onto a substrate.
