Patent number: 5996906Abstract: The present invention is an apparatus and method to reduce unwanted spraying of fluids from hose nozzles. In the preferred embodiment of the invention, a hole filled cover is attached over an open end of the nozzle of the hose.

If the nozzle moves to a position where unwanted spray is likely to take place, the cover deflects over the liquid stream causing it to be disbursed or scattered rather than sprayed over a long distance. The invention finds particular application in the prevention of spraying of water from the high pressure cleaning nozzle in swimming pool cleaners onto nearby objects or persons.Type: GrantFiled: January 5, 1998Date of Patent: December 7, 1999Inventor: J.

Patent number: 5810261Abstract: A zero velocity head nozzle for effecting aerated discharge of water is disclosed which produces constant maximized zero velocity aerated water flow from a high pressure source. Two hollow, opposed and non-perforate hemispherical chambers are separated by a discharge gap at an equator separating the opposed hemispherical chambers. High pressure water inflow is introduced at the pole of one hemisphere, impacts the opposite pole of the opposed hemisphere, and thereafter sets up a generally toroidal energy dissipating flow path between the opposed hemispherical sections. At the same time, the underside of the hemisphere opposed to the input defines a convenient aeration input to the energy dissipating toroidal flow path. As a direct consequence, water flowing in the toroidal flow path is visibly entrained with miniature bubbles. Outflow of water intermixed with the bubbles occurs at the discharge gap between the opposed hemispherical sections with only a slight upward flow occurring toward the input.Type: GrantFiled: September 30, 1996Date of Patent: September 22, 1998Inventor: George A. Winters

Patent number: 5694898Abstract: The injector comprises a body (1) with a tip (2) exhibiting at least one calibrated outlet hole for jets of fuel as well as a skirt (25) for dispersing the fuel received in the form of jets, the skirt (25) being tubular and extending the body (1) to which it is fixed by its upstream part (14), and its downstream part (26) is formed, at least toward the downstream end, by at least one lateral wall thinned to a bevel (28) of thickness decreasing toward the downstream end as far as its downstream free edge in the form of a thinned blade (29). For preference, a concave notch turned toward the downstream end is formed in the free edge of each bevel, and each jet (J1, J2) of fuel from the two-hole injector strikes a region (30) on the internal face of a lateral wall of the skirt.Application to injectors, particularly multi-hole injectors, for automobile engines.Type: GrantFiled: November 27, 1995Date of Patent: December 9, 1997Assignee: Magnetic Marelli FranceInventors: Michael Pontoppidan, Bruno Covin, Jean Christopher Lucas, Christophe Preterre

Patent number: 5616067Abstract: In an apparatus for cleaning a workpiece with abrasive CO.sub.2 particles, a CO.sub.2 nozzle receives and expels liquid CO.sub.2 through at least one orifice sized for at least partially converting the liquid into CO.sub.2 particles. The CO.sub.2 particles are injected into a converging-diverging nozzle at a location adjacent to the throat section thereof. Pressurized air is directed into the converging section of the nozzle upstream from the throat section. The pressurized air accelerates the CO.sub.2 particles which are focused by the diverging section of the nozzle for impacting the pressure-sensitive surface of the workpiece to be cleaned.Type: GrantFiled: January 16, 1996Date of Patent: April 1, 1997Assignee: Ford Motor CompanyInventor: Lakhi N.

Patent number: 5516043Abstract: An ultrasonic atomizer device comprises an elongate body member having a proximal end and a distal end, the elongate body member being provided at least along a distal segment with a longitudinally extending liquid guide channel. The body member is further provided at its distal end with a radially enlarged head and at least one orifice communicating with the channel at a distal end thereof, the orifice extending to an atomizing surface disposed externally to the body in a recess on a proximal side of the head. The body is also provided with means for forming an operative connection with a source of ultrasonic vibrations.Type: GrantFiled: June 30, 1994Date of Patent: May 14, 1996Assignee: Misonix Inc.Inventors: Ronald R. Manna, Vaclav Podany, David Ng, Thomas H. Costa, Vernon Zeitz, deceased

Patent number: 5392989Abstract: An improved nozzle assembly for dispensing liquid is disclosed. In a first embodiment of the invention, the liquid dispenser comprises a nozzle assembly with an expansive cavity at its dispensing end. When the flow of liquid in the dispenser is halted, a pocket of liquid formed inside the cavity ties the liquid in the nozzle to the liquid in a drop formed at the tip of the nozzle. Thus, when "suck-back" is applied, the drop is pulled into the cavity and up the nozzle, leaving at most a very small and stable amount of liquid inside the cavity. In a second embodiment of the invention, an inner nozzle tube extends beyond the end of an outer nozzle tube, creating an external annular recess which captures and holds a drop of liquid over the end of the nozzle. After suck-back, the drop is pulled up into the nozzle, leaving a small, stable amount of liquid in the annular recess.Type: GrantFiled: May 24, 1994Date of Patent: February 28, 1995Assignee: Semiconductor Systems, Inc.Inventor: Roy E. Hurtig

Patent number: 5344079Abstract: A foaming nozzle mounted in front of a spray nozzle of a sprayer so that a liquid detergent may be sprayed in a foamed state onto a window glass or tile for cleaning. The foaming nozzle has its mouth shaped so that a mixed cluster of the mist and foam from the foaming nozzle is injected in a band, elliptical, rectangular or triangular shape and at a wide angle. A predetermined relationship between a spray port and the foaming nozzle allows the mist spin-injected at a high swirling speed to be partially mixed with the foam. The foam is formed by the impingement of the mist upon an inner face of the mouth of the foaming nozzle. The mixture may be injected at a wide angle. The foaming nozzle can be composed of first and second nozzles wherein the second foaming nozzle is of a circular cylinder and hingedly mounted to the first foaming cylinder. The user can selectively inject either a mist-foam mixed cluster having the band section or a foam cluster having a circular section.Type: GrantFiled: May 20, 1992Date of Patent: September 6, 1994Assignee: Yoshino Kogyosho Co., Ltd.Inventors: Takaharu Tasaki, Tadao Saito

Patent number: 5335860Abstract: Described is a preferred rotary spray chamber device for conditioning an aerosol. The device has chamber walls defining an internal chamber and an inlet opening into the internal chamber. The inlet opening is located such that an aerosol directed into the chamber through the inlet opening tangentially contacts chamber wall areas adapted to impart a rotary motion to the aerosol within the chamber. An impact member extends inwardly into the chamber from a chamber wall location such that the member is impacted by the aerosol in its rotary motion so as to remove large droplets and thus form a conditioned aerosol. An exit opening is defined by the chamber walls through which the conditioned aerosol can exit the chamber, and a drain opening is also defined by the chamber walls through which liquid removed from the aerosol and collected in the chamber can exit the chamber.Type: GrantFiled: January 8, 1993Date of Patent: August 9, 1994Assignee: Indiana University FoundationInventors: Gary M. Hieftje, Min Wu
