Patent number: 6827299Abstract: A liquid spray module which can be individually used, or which can be easily mounted in ganged side-by-side relation with a plurality of such modules. Each module includes a spray gun cartridge having liquid passages through the liquid to be sprayed, is directed and one or more air passages through which pressurized air may be directed for assisting in atomization of the liquid and controlling operating movement of a valve needle. Each spray gun cartridge further includes a manifold body having a central bore into which the spray gun cartridge is removably mounted and liquid and air inlet and outlet passages which communicate with the liquid and air spray gun cartridge passages. The spray gun cartridge is removable from the manifold body without disconnection of fluid supply lines to the manifold body and without removal of the manifold body from a ganged mounted array of such spray modules.Type: GrantFiled: January 24, 2003Date of Patent: December 7, 2004Assignee: Spraying Systems Co.Inventors: Ronald R. Scotchmur, Gerald P. Ferrazza

Method and nozzle arrangement for a variable-width lubrication of the rolling-nip of a rolling stand
Publication number: 20040232258Abstract: The invention relates to a method for lubricating rolls, in particular for lubricating a rolling nip in rolling stands for rolled strips. According to the invention, said lubrication takes place using an oil-in-water dispersion whilst maintaining both a predetermined blend characteristic and a volumetric flow of the dispersion. The dispersion is prepared in the form of a homogeneous blend in a mixer (1) using adjustable quantities of water and oil. The dispersion is supplied to various spray zones (Zi) for a distribution (Bi) that is variable in width. Said method for roll lubrication can be improved by the allocation of at least one row of nozzles (Di) to each spray zone (Zi), which has a corresponding spray range width (Bi), each nozzle being controlled by at least one relay valve (Si).Type: ApplicationFiled: June 3, 2004Publication date: November 25, 2004Inventors: Horst Cerv, Heinz Hopfenziz, Jurgen Armenat, Rudolf-Franz Jager, Jurgen Seidel -
Patent number: 6786425Abstract: A device for delivering a controlled dose of a fluid to an outlet from a fluid supply at an operating pressure which includes an actively operable check valve and pressure exerting means to selectively exert first and second pressures on the check valve. When one of the first and second pressures is exerted on the check valve, the valve prevents the passage of fluid at operating pressure through the outlet. When the other pressure is exerted on the check valve, the valve permits the passage of spray fluid at operating pressure. Signal generating means to generate a control signal characteristic of the fluid operating pressure, and control means derive at least one of the said first and second pressures from the control signal.Type: GrantFiled: December 7, 2000Date of Patent: September 7, 2004Inventor: Matthew James Harold Rawlings

Patent number: 6739526Abstract: A coating apparatus for coating a material to be coated with a solution is disclosed, preferably for coating pharmaceuticals. A spray bar having a spray gun receptacle, a solution inlet conduit and an atomizing air conduit is disclosed. The spray gun is positionable in the spray gun receptacle and has a body portion adapted to fit in the receptacle and an insertion portion having a sealable orifice at a spraying end thereof. The body portion has an internal void constructed and arranged to be in fluid communication with the solution inlet conduit and the atomizing air conduit when the spray gun is positioned in the spray gun receptacle and the insertion portion is in an open position. The insertion portion is moveable between an open position defining a passage between the body portion void and the spraying end orifice a closed position sealing the insertion portion against the body portion to close said passage.Type: GrantFiled: March 14, 2002Date of Patent: May 25, 2004Assignee: Thomas Engineering, Inc.Inventor: James T. Wlodarczyk

Patent number: 6736340Abstract: A controlling device for a sprinkler includes multiple seals detachably received in the tube in a watertight manner. Each seal has outlets defined in a top face of the seal and passages defined to respectively communicate with a corresponding one of the outlets. Multiple controlling rods are linearly and movably received in the tube to engage with a bottom face of the seals so as to selectively block the communication between the passage and the outlets such that water inside the tube is controlled to be sprinkled out of the tube.Type: GrantFiled: May 28, 2003Date of Patent: May 18, 2004Inventor: Tzu-Meng Wang

Patent number: 6685104Abstract: Landscape sprinkling systems that incorporate fire sensors, optional moisture sensors, and control electronics that continuously monitor the perimeter of a property for fire and/or smoke, and optionally low soil moisture conditions. When an alarm is detected, the systems automatically turn on selected sprinkler valves to water areas that would be most impacted by a fire or are in need of water. Wireless and wired system embodiments are disclosed.Type: GrantFiled: July 17, 2002Date of Patent: February 3, 2004Inventors: Ardele Y. Float, Kenneth W. Float

Publication number: 20030205223Abstract: The present invention provides a burner tube. The burner tube has a proximal segment, a distal segment, a terminal end, and a plurality of fuel outlet ports. The proximal segment has a union region and is adapted to be connected to a fuel source. The terminal end of the burner tube is connected to the union region such that the terminal end is in fluid communication with the union region. The connection between the terminal end and union region forms a continuous burner tube, or a burner loop for the flow of fuel. An initial flow of fuel diverges in the union region into a first portion and a second portion. The first portion flows through the union region and downstream through the distal segment. The second portion of fuel from the fuel source flows through the union region and downstream through the terminal end.Type: ApplicationFiled: May 6, 2002Publication date: November 6, 2003Inventors: Erich J. Schlosser, Adrian A. Bruno, Mohammed Shoeb
