  • Patent number: 5366619
    Abstract: A germfree drinking water dispenser includes a reservoir for receiving and reserving drinking water such as mineral water and an ozone injecting device. The ozone injecting device includes a compact ozone generator and an injection opening which is opened into the reservoir. Ozone generated by the ozone generator is injected, by e.g. a blower, through the injection opening into the drinking water at the reservoir. The ozone injecting device is activated only for a short necessary period of time when the dispenser is out of service. So that, after the drinking water in the reservoir is fully sterilized, a sufficient period of time is allowed to lapse for any ozone remaining in the water to dissolve until the next first use of the dispenser.

  • Patent number: 5137756
    Abstract: Apparatus is provided for carrying out a varnish impregnation method wherein a sheet-like base material is sequentially passed through a low-viscosity liquid storage region storing a low-viscosity liquid such as a solvent, a thermal syphon region, and a varnish storage region storing a varnish, the thermal syphon region being positioned between the low-viscosity liquid storage region and varnish storage region and communicating with both regions at air tight seals closed by liquid surfaces, and heating the base material in the thermal syphon region to vaporize the low-viscosity liquid impregnated in the base material. When the base material passes through the low-viscosity liquid, air contained in the base material is replaced with the low-viscosity liquid and discharged outside the apparatus. The low-viscosity liquid impregnated in the material is vaporized in the thermal syphon region.

  • Patent number: 5104698
    Abstract: A method and apparatus for impregnating a fibrous base material with a varnish liquid, wherein the so-impregnated base material is substantially air free. A base material is passed under the surface of and through a supply of low-viscosity liquid such as to impregnate the base material with the low-viscosity liquid and displace air from the base material so as to provide a substantially air-free base material. The air-free base material is passed through an entrance for and into a syphon. An inert gas is supplied to the syphon so as to maintain an inert gas atmosphere therein sufficient to maintain the air-free condition of the base material. The air-free base material is then passed through an exit of the syphon and under the surface of and through a supply of varnish liquid sufficiently to displace the low-viscosity liquid from the air-free base material and impregnate the air-free base material with the varnish liquid.

  • Patent number: 4650647
    Abstract: An apparatus for removing acid constituents such as HCl and/or SO.sub.x from the waste-gas generated by furnaces,incinerators and the like wherein the calcium-containing powder material is blown into a waste-gas duct to form a lean fluidized flow until it reaches a vertical moving bed filter having two louvered walls between which granular packings are filled. The process for removing the acid constituents is accomplished by chemisorption which occurs first in the duct and then in the filter bed. A recycled use of the powder is preferred. The filtered waste-gas is further purified by an electrostatic precipitator. The use of a moving bed filter permits the use of a greater amount of calciumaceous powder relative to the acid gases without increasing the electrical load on the electrostatic precipitator.
