Patent number: 6776360Abstract: A gun-like spray device having a spray nozzle assembly at the discharge end and a reciprocatably movable valve needle for controlling the liquid flow through the discharge nozzle assembly. The nozzle assembly includes an orifice member which defines a liquid discharge orifice and a rigid valve seat for centering and precisely locating the valve needle in a closed position. An annular resilient sealing member is secured within the orifice member for engaging and creating a liquid seal about the valve needle separate and apart from the rigid seat when the valve needle is in a closed position. The spray nozzle assembly may be used with spray devices having different sized valve needles and includes a first rigid valve seat downstream of the resilient sealing member for receiving a relatively small diameter valve needle and a second rigid valve seat upstream of the resilient sealing member for receiving a relatively large diameter valve needle.Type: GrantFiled: June 26, 2001Date of Patent: August 17, 2004Assignee: Spraying Systems Co.Inventors: James Haruch, Gerald P.

Patent number: 6766864Abstract: The invention relates to a method and a device for distributing liquid media, in particular extinguishing fluids. The aim of the invention is to provide a method and a device of the aforementioned type which can be used to produce a fine mist of small droplets and a jet spray of large droplets at separate moments, at approximately the same operating pressure of the extinguishing fluid, depending on the outbreak and the development of the fire, whilst at the same time minimising water consumption, reducing water damage caused during a fire and increasing cost-effectiveness, by creating a modular system which can be universally installed. To achieve this, the intensity of the vortex and the proportion of fine or large droplets in the spray cone is adjusted by regulating the quantity and speed of the flow during the distribution of the extinguishing fluid in at least two sub-streams and by combining said sub-streams with at least one additional sub-stream.Type: GrantFiled: October 15, 2002Date of Patent: July 27, 2004Inventors: Torsten Clauss, Andreas Schmidt, Wassili Jansen

Patent number: 6758375Abstract: The improved container for storing and dispensing liquids has a baffle which resists spilling and pours more smoothly than prior containers. The baffle may be located between the mouth opening and the interior of the container chamber. When the improved container is tilted for pouring, such that the liquid level inside the container chamber is higher than the liquid level at the mouth opening, no liquid pours out of the container. The liquid starts to flow out of the mouth opening only after the container is tilted beyond a predetermined start-to-pour angle. The start-to-pour angle is reached when the container is tilted to allow the outside air to enter the container chamber. The baffled container may have an optional notch on the baffle to reduce glugging and to result in a smoother pour. The improved container can be manufactured in a simple one-step blow molding process.Type: GrantFiled: January 9, 2002Date of Patent: July 6, 2004Inventor: I-Chung Ho

Patent number: 6755355Abstract: A coal gasification nozzle is disclosed having a barrier, integral with the face of the injector, that fits into a groove of a heat shield attached to the nozzle face. The barrier prevents oxidative corrosion of the shield, and subsequent damage to the underlying face of the feed injector, by preventing diffusion of corrosive species to the threaded ring by which the heat shield is attached to the face of the nozzle. The life of the injector, and thus the length of any single gasification campaign, is thereby extended.Type: GrantFiled: April 18, 2002Date of Patent: June 29, 2004Assignee: Eastman Chemical CompanyInventor: Gary Scott Whittaker

Patent number: 6752323Abstract: A hot melt high temperature material application system with application device pressure monitoring and heated recirculating manifold uses high temperature pressure transducers with each application device such as spray guns to monitor hot melt material application. A material supply line fitting has a calibrated orifice at the interface with a device manifold associated with each application device. In another embodiment, the calibrated orifice is located in a fluid passageway of the device manifold. The calibrated orifice corresponds in size to the opening of a nozzle of the application device. Heated recirculating manifolds are combined with hot melt material supply systems to provide uniform pressure to multiple application devices, and to recirculate material back through the supply system. Each recirculating manifold includes a heater, pressure regulator, and a recirculation path. The manifolds may be directly or remotely connected to one or more hot melt material supply systems.Type: GrantFiled: August 23, 2001Date of Patent: June 22, 2004Assignee: Nordson CorporationInventors: John P.
