  • Patent number: 5904901
    Abstract: A purpose of this invention is to provide an apparatus which can carry out a deodorization/odor-removal/disinfection work even on a large-scaled matter such as a room etc. effectively and efficiently. A deodorization/odor-removal/disinfection apparatus of this invention is equipped with an ozone generator (1), an ozone blow-off mechanism which blows generated ozone from a blow-off port (12), a device (2) which atomizes aqueous hydrogen peroxide, and an aqueous hydrogen peroxide blow-off mechanism which blows the atomized aqueous hydrogen peroxide from a blow-off port (32). This apparatus generates ozone and at the same time produces aqueous hydrogen peroxide under atomized state, makes the both contact each other and then makes them contact with an object.

    Abstract: A clothing deodorizer for deer hunters. The deodorizer includes a bag in which is placed the clothing to be deodorized of human odor. Within the bag a perforated container holds a granular material which can adsorb the human odor from the clothing. An object which can pulverize the granular material is placed in the container, so that as the bag is tumbled e.g. in a clothes dryer the object grinds the granular material into a powder which comes out through the perforations, contacts the clothing, and adsorbs the human odor exuded by the clothing.

  • Patent number: 5478505
    Abstract: An air-treating article for dispensing a volatilizable material, such as air freshener fragrance, into the atmosphere of an enclosed area, such as an automobile interior. The device includes a housing and a reservoir of the volatilizable material therein, and also includes a dual-configured, articulating attachment clip which enables attachment of the device at a high-air-flow station, such as the forced air vent grille of the automobile, or at a low-air-flow station, such as the sun visor of the vehicle. The device enables use of the consistent delivery rates of a low-density polyethylene membranes while at the same producing a higher delivery rate than normally achieved with such membranes.

  • Patent number: 5447693
    Abstract: A deodorant equipment for an air conditioner includes a heater. A fin covers at least a part of an effective heating area of a surface of the heater. The fin has a radiator portion extending along a longitudinal direction of the heater. A vitreous coating film covers at least a part of an outer surface of the fin. A catalyst layer includes an absorption member and a catalyst. The absorption member absorbs odor components of air. The absorption member releases the odor components when being heated. The catalyst oxidizes and decomposes odor components when being heated.

  • Patent number: 5445798
    Abstract: A microbe propagation preventing apparatus and a microbe propagation preventing method are provided to prevent an ion from decreasing at a time of decomposing ozone generated by gaseous discharge or ionization so as to sufficiently generate air ion, and to sufficiently prevent propagation of microbes adhering to an object by using the air ion without secondary pollution. Further, in the apparatus and the method, a gas containing the ion is supplied into water so as to prevent the microbe propagation in the water. In the apparatus, an ozone decomposing chamber is mounted to be electrically insulated from an air duct. An electrode to remove a positive ion is mounted to obtain only a negative ion, and extend a lifetime of the obtained ion. An ion supplying portion is mounted to supply an ionized gas into a space housing the object in which microbes can be propagated, and return the ionized gas to an ionization chamber.

  • Patent number: 5443798
    Abstract: A separator plate for a chemical oxygen generator candle includes an elongate rigid thermal insulating section; and at least a first conduit section on one side of the rigid section having a multiplicity of gas flow paths for conducting released oxygen from a burning candle longitudinally along the plate for increasing the burning action of the burning portion of the candle and pre-heating the unburned portion of the candle, and for retaining gas to act as a thermal insulator when the candle is not burning. A plurality of such plates are combined to form a separator assembly for surrounding a candle and a number of such separator assemblies are combined to form a multi-candle oxygen generator.

  • Patent number: 5433923
    Abstract: A room humidifier and air purifier withdraws air from ambient room atmosphere into a region having a living plant with its roots in a growing media of highly adsorbent activated carbon and zeolite; passing air preferably downward through such media and back into the air over hot light bulbs which destroy undesirable airborne mold spores. The light bulbs are also used to supply sufficient light for plant growth and aesthetics through indirect lighting on the plant leaves.

  • Patent number: 5429180
    Abstract: A perfume generating device for preventing a reduction in the level of a consciousness by a supply of relaxing-type aromatic agent, and for preventing a reduction in concentration. Different containers for relaxing-type and refreshing-type aromatic agents and valves for selecting one of the agents are provided on a perfume supply conduit. Upon the selection of the relaxing-type aromatic agent, a repetition of cycles are executed such that, after each three cycles of a relaxing-type aromatic agent, a single supply of refreshing-type aromatic agent or stoppage of the supply of the relaxing-type aromatic agent is performed.

  • Patent number: 5422078
    Abstract: An apparatus and method for providing a scent to a compartment comprising a reusable holder having a connecting means and a scented card insertable into the holder. The connecting means can be a clip which is connectable to a louver of an air duct outlet register of a forced air system or to a fan guard of a utility fan. The apparatus can also be modified to attach to an interior surface of a refrigerator and may even be adaptable for use as costume jewelry. The scented card is produced by a process wherein a heat extrudable thermoplastic material is mixed with a chemical blowing agent and at least one fragrance and optionally a coloring agent, the mixture of material and fragrance is heated and extruded to produce a flat fragrant sheet of material which after being trimmed, forms a relatively rigid but flexible card insertable into the holder and removable therefrom.
