    NOTE ON RELATED APPLICATIONS
    This application is a continuation of US Patent Application No. 12 / 026,006 filed on Feb. 5, 2008, the contents of which are incorporated herein by reference in their entirety.
    BRIEF SUMMARY OF THE INVENTION
    The present invention relates to an apparatus for the production of flying foam moldings and a method for advertising using floating foam moldings.
    For the foam to fly, the total mass of a given volume of foam must be less than that of the air displaced by that volume (Archimedes' principle). It is desirable to have foam with a large bubble size. Large bubble size foam has a percentage of water to surfactant of 86% or less, and an expansion ratio of more than 200. Larger bubbles within the foam contain more gas and therefore have more buoyancy. Dense packed foam, also called low expansion foam, has a small bubble size.
    An example of heavy foam is shaving cream. Heavy foam is not desirable for incorporation in flying foam. Heavy foam does not include enough gas to produce the desired buoyancy effect.
    The gas for producing foam, which is lighter than air, must have special properties in order to produce the buoyancy effect. Ideally, the gas should have a molecular mass of less than about 28.97. The molecular mass is the mass of one molecule of the substance relative to the atomic mass unit u (equal to 1/12 of the mass of the carbon atom 12C). Many chemists use the molecular mass as a synonym for molar mass, which differs only in the unit. As used herein, they are considered synonymous. For example, hydrogen has a molecular mass of about 1 or 1 atomic mass unit (amu); Acetylene has a molecular mass of about 26.0373.
    There are numerous compounds and elements which satisfy the desired conditions for molecular mass. Some examples of suitable gases include, but are not limited to, helium, hydrogen, methane, ammonium, neon, acetylene, hydrogen cyanide, ethylene, carbon monoxide, hydrogen fluoride, diborane, nitrogen, heated ambient air, and mixtures thereof. In addition, the gas may be compressed ambient air mixed with a gas lighter than air. This list is not exhaustive but should only illustrate some suitable gases.
    In addition, heated ambient air may be used to provide the desired buoyancy effect. Charles's law states that the density of gas can be reduced by raising the temperature while maintaining intrinsic pressure. For example, hot air balloons produce high lift to fly. The height of the hot air foam can be regulated by controlling the relative temperature of the extruded foam.
    In a preferred embodiment, a gas which is lighter than air, introduced into a reservoir containing a foam-forming solution. Preferably, the foam-forming solution is a water-based solution comprising at least one surfactant.
    The present invention provides an apparatus for producing floating show moldings. A container containing a foam solution has a 1/17 Austrian Patent Office AT12 461 U1 2012-05-15
    Gas line for introducing the gas into the interior of the solution container. The gas line has a first end and a second end. The first end of the gas line is outside the foam solution tank and is connected to a gas source. The gas flows from the source through the gas line into the foam solution tank and exits at the second end of the gas line into a venting arrangement. The gas entering the room is preferably regulated by a known gas cylinder pressure regulator to less than about 414.103 pascals (60 psi). The second end of the gas inlet has a vent. In a preferred embodiment, the vent nozzle has openings ranging in size from about 1.57 to about 3.17 millimeters (0.062 - 0.125 inches) in diameter. The vent nozzle disperses the gas throughout the foam solution.
    As gas is introduced into the solution chamber, foam is produced on the surface of the solution. As foam is continually being made, the difference in air pressure within the solution container relative to the pressure outside the solution container pushes the foam upwardly toward the openings in an attachment or logo board. The foam is extruded through a stencil-shaped opening which is incorporated into the surface of the solution chamber cap, which is, for example, a logo board. On the solution chamber assembly, a foam mold separator is arranged. In one embodiment, the separator is a cutting blade. The cutting blade is a mechanism which separates an individualized foam molded article from the extrudate or extruded foam molded article and does not necessarily require any degree of sharpness. Once the blade has separated an extruded body, the foam body floats from the top of the chamber into the air.
    Foam produced by conventional surfactants is usually white in color. The present invention also allows the addition of a dye to the foam solution. Any acceptable dye can be added. One type of acceptable dye is commonly used for coloring foods, medicines and cosmetics. These dyes include, but are not limited to, FD & C (Food, Drugs and Cosmetics, United States Federal Food, Drug and Cosmetic Act) Blue # 1 (Brilliant Blue, FCF), FD & C Blue # 2 (Dark Blue, Indigotine), FD & C Green No. 3 (Blue Green Shade, Fast Green FCF), FD & C Red No. 40 (Allura Red AC), FD & C Red No. 3 (Pink Shade, Erythrosine) FD & C Yellow No. 5 (Tartrazine), FD & C Yellow No. 6 (Orange Shading, Tartrazine). The colors may include combinations of the dyes.
    The present invention also includes the ability to produce a combustible foam molding. Flammable foam is made by using a combustible gas, as gas lighter than air. The combustible gases include, but are not limited to, methane, acetylene, ethylene and hydrogen. The combustible foam can be ignited by any known ignition source. The pyrotechnics and fireworks industry uses wireless and chemical firing techniques, including, but not limited to, chromium nickel wire and potassium chlorate. Flammable foam can create a striking visual effect at night, in which the flammable foam is opposed to a dark night sky.
    The present invention further includes the ability to produce a foam molded article which is sensitive to ultraviolet or black light. Foam that illuminates when illuminated with black light can be achieved by adding a black light-sensitive compound to the introduced gas and / or foam solution. Such compounds may include, but are not limited to, quinine, vitamin B-12 and stilbene.
    The present invention further includes the ability to produce luminescent foam in the dark.
    A bioluminescent and / or chemiluminescent compound can be added to the admitted gas and / or the foam solution. Some luminescent compounds may include luminol (5-amino-2,3-dihydro-1,4-phthalazinediones), cyalume (diphenylethanedioate), ruthenium (II) tris (bipyridine ), but are not limited to dichloride, oxalyl chloride and pyrogallol. In addition, luciferases which have bioluminescent properties and are routinely isolated from fireflies, marine animals and bacteria can be used.
    Also included in the present invention is a method of using the flying foam to produce a well-known logo as an advertising medium. There are numerous forms that have become widely known, and identify specific companies and products.
    The present invention also encompasses the use of multiple foam-generating containers which can produce any or a combination of several forms at once, several forms in succession, or several forms which combine in the air.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
    The present invention comprises a flying foam device 5 having a solution tank 10 with an open end 25. At the open end 25, a logo board 60 is arranged, which is attached to a fastening ring 20 releasably attached to the tank 10. The tank 10 has a circumferential vertical side 18, which is substantially perpendicular to a tank bottom 15. The logo board 60 may be removed by releasing the mounting ring 20 to introduce a foam solution into the tank 10.
    The fastening ring 20 further includes a Schneidarmvorrichtung 75, which is mounted in the circumferential direction on the mounting ring 20. The Schneidarmvorrichtung 75 has a cutting arm 40 which is movable about an axis of rotation 50. The rotation axis 50 is connected to a motor 30, which further comprises a timer 80. The motor 30 electronically moves the cutting arm 40 over the upper planar surface of the logo board 60. Further, the cutting arm assembly 75 includes a pair of stop buffer protrusions 110 which limit movement of the cutting arm 40. A limit switch 100 is electronic with the 3/17 Austrian Patent Office AT12 461 U1 2012-05-15
    Motor 30 connected. When the cutting arm 40 contacts the limit switch 100, the direction of the motor 30, and thus the direction of the cutting arm 40, is reversed. The change in the motor direction leads to the reverse movement of the axis of rotation 50 and thus of the cutting arm 40th
    The logo board 60 includes an opening 65 which is shaped as desired to produce an extruded foam molded body 90.
    The tank 10 also includes an inlet 120, which is designed to connect a gas line 160. A vent assembly 70 is mounted in the interior of the tank 10 on the floor 15. The vent assembly 70 includes a vent inlet 72 that is configured to connect to a gas line 160. The vent assembly 70 additionally includes a vent head 71 to disperse the gas throughout the solution contained in the tank 10.
    The embodiment of the present invention shown in Figure 3 may comprise a mixture of two or more gas pressure bottles. A gas pressure cylinder 180 with atmospheric air and a gas line outlet 190 may be combined with a gas cylinder 150 having a gas lighter than air and a gas line outlet 210. Gas line outlets 190 and 210 are connected via a "Y" connection 170 to direct the combined gas into a single gas line 160. The gas pressure bottle 180 has an outlet pressure regulator 130. The gas pressure bottle 150 has an outlet pressure regulator 140. Each regulator 130 and 140 can be independently adjusted to provide a desired mixing composition of the gases from each pressure bottle 180 and 150.
    The gas line 160 passes through the gas line inlet 120, which is installed in the outer wall 18 of the tank 10. The gas line 160 is attached to the mating inlet 72 of the vent assembly 70. Preferably, the mating gas inlet 72 is chamfered as known and the gas conduit 160 is mounted and held in place by the tension applied to the inner walls of the gas conduit 160. The vent assembly 70 has a vent nozzle 71 for distributing the supplied gas into the solution contained within the interior 19 within the tank 10.
    In the embodiment shown in Fig. 4, the foam mold 200 may be a word.
    In use, the fixing ring 20 is detached from the periphery of the upper part of the container wall 18, which has the container opening 25. A solution suitable for the preparation of the foam, such as that described above, is introduced through the container opening 25 into the inner region 19 of the container 10. The mounting ring 20 surrounds the periphery of the logo board 60. The mounting ring 20 with the cutter arm assembly 75 attached thereto is secured over the container openings 25 about the top of the container wall 18.
    In use, the electric motor 30 alternately reciprocates the axis of rotation 50 and the cutting arm 40 attached thereto. The cutting arm 40 reciprocates along the upper planar surface of the logo board 60 and said reciprocating motion is effected by the limit switch 110 disposed on the surface of the logo board 60. The speed of movement and reciprocation of the cutting arm 40 is adjustable by use of the motor-timer mechanism 80.
    In use, the gas flow is introduced through at least one source of compressed gas. The gas may be gas, which is lighter than air, from the gas pressure cylinder 150, or a combination of the gas, which is lighter than air, from the gas pressure cylinder 150 may be mixed with ambient air from the gas pressure cylinder 180. The gas pressure bottle 150 has the metering valve 140 and the gas pressure bottle 180 has the metering valve 130.
    Compressed gas moves through the gas line 160. The gas line 160 enters the container 10 through the inlet 120. The gas line 160 is attached to the gas inlet 72 of the vent assembly 70. The gas leaves the ventilation arrangement 70 via the ventilation nozzle 71. The gas is distributed in the solution which is contained in the interior 19 of the container 10. As the gas mixes with the foam solution 220, foam 230 is created on the surface of the solution 220. Gas pressure is generated by entering into the interior 19 of the container 10 compressed gas. The logo board 60 has an opening 65 which forms an exit to the outside of the container 10. The outside of the container 10 is at about atmospheric pressure. The gas and the generated foam are pushed up by the pressure difference between the inside of the container 10 and the outside atmospheric pressure. The foam 230 moves upwardly from the surface of the foam solution 220, as indicated by the arrow in FIG. The foam is pressed against the underside of the logo board 60 and is extruded through the opening 65 in the logo board 60. The extruded foam over the surface of the logo board 60 is separated by the cutting arm 40 into individual molds 90. The separate mold 90 then floats up and away from the device 5.
    In another embodiment, as shown in FIG. 8, the container 10 has an iris diaphragm 240 which can be opened and closed with an iris diaphragm motor 250. When an iris diaphragm 240 is used, the size of an extruded foam can be varied and would depend on the size of the aperture and the opening duration of the iris diaphragm.
    The iris diaphragm can be configured to partially or completely close. In addition, when the iris diaphragm partially closes, the iris diaphragm may be used in cooperation with the cutting arm as described above.
    In the embodiment having the iris diaphragm 240, the flying foam may have similar shapes of different sizes, which may be either interconnected or individualized.
    In an alternative embodiment, an iris diaphragm may be formed with any possible combination of circular and rectangular openings which interact to change the extruded shape.
    The present invention may also include an electronic and computer controlled iris diaphragm to change the shape of the foam during extrusion and prior to separation of said foam from the device.
    In one embodiment, as shown in Fig. 9, the solution container 10 is disposed within a housing 270. The housing 270 has walls 280 and doors 340 surrounding the container 10. The housings 270 have an upper surface 380 on which a template 60 is positioned over the container 10. The housing 270 has inner wall portions 290 which extend upwardly beyond the upper surface 380. The housing 270 further includes rollers 370 for displacing the housing 270 and the device 5 contained therein. In the embodiment of FIG. 9, the inner wall portions 290 project upwardly about 0.15 to 0.61 meters (6 to 24 inches) beyond the upper surface 380. The inner wall sections 290 deflect wind away from the surface 380. In a windy environment, the wind may sweep over the upper surface 380 and prematurely remove the extruded floating foam body from the openings 65 in the logo board 60. The extruded floating foam mold 90 has a thickness of approximately between 0.05 to 0.5 meters (2 to 20 inches). Wind, which prematurely separates the extruded floating foam molded body 90, would produce molded articles of non-uniform thickness. The desired thickness is determined in part by the complexity of the shape to be extruded.
    A patch panel 300 has paired control valves 310 and 320 which independently regulate the input of gas to the apparatus. The input gas may be a single gas or a mixture of gases as desired. A visual meter 300 monitors the input of the gas. A refill reservoir 350 and a solution line 360 are mounted on the inside of the doors 340 of the housing 270. In one embodiment, a conduit 400 supplies compressed air and a conduit 410 with helium to the apparatus 5. As noted above, a valve or pair of valves 310 and 320 are constructed and arranged to independently regulate more than one gas line to the apparatus 5. A power cord 420 provides the required 5/17
