Patent number: 6783087Abstract: An injector has an orifice plate formed with plural orifices. At a radially outward position of the orifice plate is disposed a wall at least partially. It is preferable that the wall be disposed at a lower position in the direction of gravity. In the wall is formed a guide hole toward an area on the orifice plate where a strong negative pressure is developed. A portion of fuel injected from the injector adheres as adhered fuel to the orifice plate or the wall. Under the action of a negative pressure on the orifice plate the guide hole sucks in the adhered fuel and returns it onto the surface of the orifice plate. The adhered fuel flows from the wall onto the surface of the orifice plate and again joins a fuel jet injected from the orifices. By utilizing a negative pressure developed near the plural orifices, the adhered fuel can be recovered and again injected. Consequently, it is possible to decrease the amount of adhered fuel.Type: GrantFiled: April 9, 2002Date of Patent: August 31, 2004Assignees: Nippon Soken, Inc., Denso CorporationInventors: Fumiaki Aoki, Nobuo Imatake, Kimitaka Saito, Kenji Kanehara, Akinori Harada

Patent number: 6702203Abstract: The present invention relates to a dual spray gun for painting and cleaning, and more particularly, to a combined tin and pipe dual spray gun for painting and cleaning, which can be used separately and independently, increasing working radius at will, and can be used in unitized construction, depending on the working environments. The present invention includes a T-shaped main body, which is connected with an air blow-gun at a back end, and connected to a blow head at a front end. A pipe is secured on a vertical sucking tap hole. A tank is connected on a tip end of the pipe to construct a combined tin and pipe structure. The tank can be connected on the T-shaped main body directly to construct a tin structure or the pipe can be connected on the T-shaped main body to construct a pipe structure. So the three structures can meet necessities of any working environment so that the working radius is extended infinitely.Type: GrantFiled: February 4, 2002Date of Patent: March 9, 2004Inventor: Wuu-Cheau Jou

Publication number: 20040035947Abstract: A method and apparatus for producing man-made snow without using either compressed air or high-speed fans. The method makes use of a special water nozzle that is designed to provide a high volume spray of water particles that, owing to their size distribution (having a median size of between about 100 and 200 microns) in the spray, are readily susceptible to conversion to ice crystals as they settle to earth under favorable ambient conditions. Preferably, water applied to the nozzle is seeded with artificial nucleation sites so that water particles in a spray containing such sites are more susceptible to conversion to ice crystals as the particles settle to earth.Type: ApplicationFiled: August 10, 2002Publication date: February 26, 2004Inventor: H.

Patent number: 6695686Abstract: The present invention relates to a method and a device for generating a two-phase gas-particle jet for treating surfaces by means of particles, in particular CO2 dry ice particles (22), using a two-phase gas-particle jet. To this end, the CO2 dry ice particles (22) are fed with a, tangential flow to a blasting chamber (30) in such a manner that the CO2 dry ice particles (22) are forced into a rotational movement about an axis of flow (50), the angular velocity of this rotational movement then being increased in the direction of flow by means of a blasting nozzle (40), so that maximum speeds occur in the blasting-nozzle outlet (42). The two-phase gas-particle jet emerging from the blasting-nozzle outlet (42) is formed in such a way that the solid-phase CO2 dry ice particles (22) are arranged in a uniform ring shape with an enlarged external diameter. The invention achieves in particular a considerable rise in the surface power when cleaning surfaces by means of CO2 dry ice particles (22).Type: GrantFiled: December 4, 2000Date of Patent: February 24, 2004Assignee: L'Air Liquide Societe Anonyme a Directoire et Conseil de Surveillance pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Hans Frohlich, Sabine Gebhardt, Berthold Trampusch

Patent number: 6691928Abstract: A high efficiency method for atomizing a liquid fuel. A liquid fuel is caused to flow into and through a pre-atomization chamber. A first portion of a pressurized atomizing fluid is introduced into the liquid fuel flowing through the chamber so as to at least partially atomize the fuel and provide a first admixture containing atomized fuel and atomizing fluid. The first admixture is delivered from the chamber and caused to flow into and through a first elongated port in an atomizing tip connected to the chamber. A second portion of pressurized atomizing fluid is directed into and caused to flow through a second elongated port in the tip. The first admixture from the first port is introduced into the second port and caused to become intimately intermixed with the second portion of pressurized atomizing fluid so as to further atomize the fuel and provide a second admixture comprising atomized fuel and atomizing fluid.Type: GrantFiled: March 14, 2002Date of Patent: February 17, 2004Assignee: John Zink Company, LLCInventors: I-Ping Chung, Christoph Strupp

Publication number: 20040026535Abstract: A liquid two part cleaning composition for hard surfaces, and a two chamber bottle for dispensing the cleaner are disclosed. The cleaner includes a first basic liquid and a second acidic liquid. At least one of the liquids includes a surfactant system. At least one of the liquids includes a foam inhibitor. When the first and second liquid are dispensed on a surface, carbon dioxide gas released instantaneously creates a quickly breaking foam on the surface. The bottle has horizontal orientation of the first and second chamber that assures a user's thumb is on the front wall and a user's fingers are on the rear wall of the bottle when dispensing. The horizontal orientation provides an ergonomically advantageous wide range of motion. The positioning of a user's thumb on the front wall of the bottle allows for design adjustments in the bottle to achieve equal dispensing from both chambers.Type: ApplicationFiled: August 9, 2002Publication date: February 12, 2004Inventors: Simon M.

Publication number: 20040026528Abstract: A fluid spray is provided by apparatus (12) which includes jet spray (13) means for producing at least two jets of fluid (10,11). The jets of fluid at least partially intersect to thereby provide a predetermined spray pattern of fluid, preferably fan shaped. The jets of fluid (10,11), from nozzles, can be directed towards a vehicle windscreen or headlamp.Type: ApplicationFiled: June 20, 2003Publication date: February 12, 2004Inventor: Martyn Jenkins

Patent number: 6666385Abstract: The plural component striping spray system and method involves mixing two spray components by pumping them under pressure from heated supply systems and converting them into a fine spray within a spray gun where they mix by impingement before being blown out through a common spray tip orifice. The initiation and termination of spray from the spray tip is controlled by a shutoff needle, and the design of the mixing chamber, needle and spray tip are such that no mixed material is allowed to stay in the spray gun to cure and freeze up the gun. When the components are a resin and a catalyst, pure catalyst is the first and last material sprayed from the spray gun. The system includes a recirculation system which can become operative when the operation of the spray gun is terminated.Type: GrantFiled: August 11, 2000Date of Patent: December 23, 2003Inventors: John Gonitzke, David E.

Patent number: 6637731Abstract: A diffuser for use in a pressurized feed system. The diffuser introduces a carbonic acid solution into water to be treated. The carbonic acid solution within the diffuser is maintained at an elevated pressure. As the carbonic acid solution passes to the exterior of the diffuser, the pressure drop causes an effective mixing of the carbonic acid solution and the water. The carbonic acid solution mixes with the water and the pH of the water is reduced.Type: GrantFiled: October 11, 2002Date of Patent: October 28, 2003Assignee: Tomco2 Equipment CompanyInventor: Tommy J.
