  • Patent number: 4790482
    Abstract: The invention relates to a liquid atomizer having a liquid atomizing rotor rotatable about an axis, and designed to feed a liquid into its inlet, along a liquid flow surface of the rotor and through its outlet as an atomized spray. The liquid flow surface is formed by a bent sheet member, fluted or zig-zag in formation, forming a closed figure surrounding the axis, and two generally symmetrically formed sheet portions, and doubler seams on diametrically opposite sides of the sheet portions for counterbalancing during rotor rotation about the axis.

  • Patent number: 4624411
    Abstract: A self-propelled, rotary liquid atomizer having a feed tube and a rotor operably connected at the bottom thereof. The feed tube is hollow and is affixed to the inlet line of a pressurized liquid source. This liquid source is not only atomized but serves as the motor force for the atomizer. A plurality of slits are formed at the bottom of feed tube and they are juxtaposed a plurality of cup-like openings and holes formed in the rotor. As the liquid under pressure is passed through the feed tubes it exits from the slits at the bottom of the feed tube and impinges upon the cup-like openings within the rotor to cause the rotation thereof. This high speed rotation causes the rotor to act as a fly wheel spinning at such high speed that it increases the momentum of the liquid forcing it up and along the walls of the rotor and out through the openings therein. As the liquid reaches the openings at the top of the rotor, it is sheared into fine droplets and sprayed/atomized at 360.degree. around the rotor.

  • Patent number: 4582255
    Abstract: A self-propelled, floating, rotary, liquid atomizer having a feed tube and a free floating rotor operably connected at the bottom thereof. The feed tube is hollow and is affixed to the inlet line of a pressurized liquid source. This liquid source is not only atomized but serves as the motor force for the atomizer as well as lifts the rotor off its support to become free floating. A plurality of slits are formed adjacent the bottom of feed tube and they are juxtaposed a plurality of cup-like openings and holes formed in the rotor. As the liquid under pressure is passed through the feed tubes it exits from the slits at the bottom of the feed tube and impinges upon the upper edges of the cup-like openings within the rotor to cause the rotor to lift from its support coincidental to rotation thereof.

  • Patent number: 4551153
    Abstract: A fuel vapor generator capable of being incorporated within a carburetor having a housing defining a chamber at the bottom thereof. An input line is attached to the lower portion of the housing for introducing a liquid fuel into the chamber and a return line is also attached to the lower portion of the housing for removing any excess liquid from the chamber and returning the excess liquid to the chamber. Located within the chamber is a level regulating system which, by being operably connected to both the inlet and removal lines is capable of regulating the liquid level within the chamber. In addition, an atomizer is located within the chamber in order to spray the liquid fuel in mist form into the upper portion of the housing for vaporization thereof prior to introduction into the Venturi tube of a carburetor.

  • Patent number: 4511084
    Abstract: A top feeding atomizer having a body, and in which the body has an open ended cutout portion at one end thereof and a chamber at the other end thereof. A plurality of longitudinally extending openings interconnect the cutout portion with the chamber. In addition, a plurality of longitudinally extending passageways interconnect the chamber with the outside of the one end of said body. Continued rotation of the body, while liquid is fed into the open end cutout portion, forces the liquid through the interconnecting openings into the chamber and from the chamber up the passageways and out the passageways in a fine globular spray.

  • Patent number: 4465559
    Abstract: An atomization/distillation unit for separating a component from a mixture containing that component having a chamber, a container incorporated within the bottom of the chamber for receiving the mixture, a heater for heating the mixture to a temperature sufficient to vaporize the component but insufficient to vaporize the entire mixture, an atomizer located within the container for spraying said mixture upward in the chamber thereby aiding in further vaporization of the component, and agitator plates operating in conjunction with the atomizer for propelling the vapor upward in the chamber. Cooling coils are located in the top portion of the chamber in order to condense the vaporized component. Once condensed, the distillate is easily removed from the chamber. The atomization/distillation system is effective in combining atomization and distillation in order to maximize recovery of the desired component in a highly energy efficient manner.

  • Patent number: 4432775
    Abstract: An apparatus for separating a substance from a liquid in which the substance is contained having a vacuum chamber, a container within the chamber for receiving the liquid and an atomizer within the container for atomizing the liquid in order to vaporize the substance contained therein. Once vaporized, the substance is withdrawn from the chamber by the vacuum producing means. A small portion of the atomized liquid is continually withdrawn from the chamber as cleansed liquid while the remainder of the atomized liquid is returned to the container for reatomization and future withdrawal. In addition to the above described apparatus, this invention also includes the method of separating a substance from a liquid.

  • Patent number: 4278519
    Abstract: An improved electrode assembly for determining the identification of metals and metal alloys having a test probe and a memory voltage indicator circuit for registering the potential difference (voltage) between the test probe and the metal to be identified. The test probe is made of a durable body having a pair of chambers therein for containing a saturated water solution of potassium chloride. A thin-walled tube is located within one of the chambers and contains therein a conductive wire and a saturated liquid mercury solution of granular calomel and potassium chloride. The voltage indicator circuit is electrically connected between the conductive wire and the metal to be identified. Utilizing the two chamber construction of the test probe substantially eliminates gas lock within the test probe and thereby allows extremely reliable and accurate readings of potential difference between the test probe and metal.

  • Patent number: 4115689
    Abstract: A leveling apparatus used in conjunction with a specimen holder and plastic film window material to accurately and consistently form a flat, bubble free analysis window on the open face of the specimen holder. The specimen holder in the form of a shallow cylindrical cup is slightly overfilled and covered by the plastic film. Placement of the mating leveling apparatus over the film squeezes out trapped air bubbles, levels the exposed face of the specimen, draws the plastic film tight over the exposed face of the specimen, and allows easy installation of a film retaining O-ring to maintain the specimen material in a level state within the holder.
