The valve of the treatment unit includes a housing, a stationary member, a slide member and a rotatable switch member unit and may also be operated in a backflush mode in which water may be directed in the reverse direction through at least one of the water treatment media to regenerate that media.Type: GrantFiled: December 21, 2001Date of Patent: September 28, 2004Inventor: Yiu Chau Chau

Patent number: 6793148Abstract: 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: GrantFiled: August 10, 2002Date of Patent: September 21, 2004Assignee: Ratnik Industries, IncorporatedInventor: H. Ronald Ratnik

Publication number: 20040099753Abstract: A fuel injector (1) for fuel-injection systems of internal combustion engines includes a valve needle (3) cooperating with a valve-seat surface (6) to form a sealing seat; and an armature (20) engaging with the valve needle (3), the armature (20) being axially moveable at the valve needle (3) and being damped, via a damping element (32), which is located in a recess (35) in a downstream-side end face (34) of the armature (20), with respect to a cup-shaped sleeve (31) positioned downstream from the armature (20) and joined to the valve needle (3) in force-locking manner. Furthermore, the fuel injector includes a filter element (25b), the filter element (25b) being positioned downstream from the armature (20) in the cup-shaped sleeve (31).Type: ApplicationFiled: July 25, 2003Publication date: May 27, 2004Inventor: Ferdinand Reiter

Patent number: 6663026Abstract: A fuel injector for controlling fuel flow to an internal combustion engine and a method of setting dynamic calibration for the fuel injector. The fuel injector has a body, a seat, an armature assembly, a resilient member, and a member. The member extends parallel to the longitudinal axis between a first portion and a second portion. The first portion supports the resilient member and engages the body, and the second portion has a filter. The method can be achieved, in part, by providing the member extending between the first portion and the second portion, fixing the filter to the second portion, moving the member along the longitudinal axis with respect to the body; and engaging the first portion with respect to the body such that the first portion supports the resilient member in a predetermined dynamic state.Type: GrantFiled: February 2, 2001Date of Patent: December 16, 2003Inventor: Robert MacFarland

Patent number: 6648247Abstract: A fuel injector and a method of setting dynamic calibration for the fuel injector. The fuel injector has a body, a seat, an armature assembly, a resilient member, and a member. The resilient member biases the armature assembly toward the second position. And the member extends parallel to the longitudinal axis between a first portion and a second portion. The first portion supports the resilient member and engages the body, and the second portion has a filter. The method can be achieved, in part, by providing the member extending between the first portion and the second portion, fixing the filter to the second portion such that the filter extends toward from the first portion, moving the member along the longitudinal axis with respect to the body; and engaging the first portion with respect to the body such that the first portion supports the resilient member in a predetermined dynamic state.Type: GrantFiled: February 2, 2001Date of Patent: November 18, 2003Assignee: Siemens Automotive CorporationInventor: Robert McFarland

Patent number: 6619567Abstract: A structure of flexible water tap with a nozzle having an extension pipe that can be pulled out from the water outgoing pipe to facilitate the rinsing and water supply, wherein the middle of the outgoing water section of the inner nozzle has an axial pipe and a plurality of passages transversally disposed in the middle section of the inner nozzle. Different elements are installed at the two water outgoing positions on the end cover in order to give different ways for the outgoing water. A splitter set is installed by passing through the middle section of the nozzle for producing a transversal displacement such that the entire structure only requires one hand to pull the nozzle from the position of the water outlet of the water tap, changes the flow path as well as the outgoing water condition, and thus attains the effect of convenient rinsing with simple control.Type: GrantFiled: July 15, 2002Date of Patent: September 16, 2003Assignee: Globe Union Industrial Corp.Inventor: Scott Ouyoung

Publication number: 20030155445Abstract: A fuel injector (1) for fuel-injection systems of internal combustion engines has a solenoid coil (10); a valve needle (3) that is mechanically linked to the solenoid coil (10) and acted upon by a restoring spring (23) in a closing direction, in order to actuate a valve-closure member (4) which, together with a valve-seat face (6), forms a sealing seat; and a sleeve (24), which prestresses the restoring spring (23). The sleeve (24) is integrally formed with a filter element (25) to form a one-part, deep-drawn filter sleeve (34), which has through-flow openings (35) for filtering the fuel flowing through the fuel injector (1).Type: ApplicationFiled: April 22, 2003Publication date: August 21, 2003Inventor: Dieter Maier

Patent number: 6607143Abstract: A fuel injector for use with an internal combustion engine. The fuel injector comprises a valve group subassembly and a coil group subassembly. The valve group subassembly includes a tube assembly having a longitudinal axis that extends between a first end and a second end; a seat that is secured at the second end of the tube assembly and that defines an opening; an armature assembly that is disposed within the tube assembly; a member that biases the armature assembly toward the seat; an adjusting tube that is disposed in the tube assembly and that engages the member for adjusting a biasing force of the member; a filter that is disposed at least within the tube assembly; and a first attachment portion. The coil group subassembly includes a solenoid coil that is operable to displace the armature assembly with respect to the seat; and a second attachment portion that is fixedly connected to the first attachment portion.Type: GrantFiled: December 29, 2000Date of Patent: August 19, 2003Assignee: Siemens Automotive CorporationInventors: Michael P. Dallmeyer, Robert McFarland, Bryan Hall, Ross Wood
