Infrared Patents (Class 159/DIG6)
  • Patent number: 5900124
    Abstract: A method of concentrating chemicals for semiconductor devices, which includes the steps of heating a sample container by using a high-energy light source, vaporizing the chemicals by injecting a high-temperature gas into the sample container through an injection opening in the sample container and discharging the vaporized chemicals by the pressure of the gas through a gas outlet formed on the sample container. An apparatus of concentrating chemicals for semiconductor devices includes a sample container having a sample-supply window, a gas-injection opening and a gas outlet. A high-energy light source heats the sample container and a gas-supply source supplies the gas through a gas-injection opening in the sample container. A gas-heating device located between the sample container and the gas-supply source heats the gas provided by the gas-supply source.

  • Patent number: 5468350
    Abstract: The apparatus includes a container for accommodating water to be treated and evaporating the water. Container is attached with water supply for supplying the water to be treated into the container. The water to be treated in container is heated by a heater. Vapor evaporated from the inside of container is cooled by a cooler. Distilled water output from cooler is irradiated with ultraviolet light by a ultraviolet light irradiator. An organic decomposed substance contained in the distilled water irradiated with the ultraviolet light is removed by organic decomposed substance removal device, and ultrapure water is obtained.

  • Patent number: 4906330
    Abstract: Hardening-shop wastewaters can be removed without salt incrustations and without creating harmful exhaust steam during the evaporation of the wastewaters only if the heat is supplied across the free liquid surface to temperatures of C. to C. and a flow of air is conducted across the free liquid surface.

  • Patent number: 4800252
    Abstract: An apparatus for heating liquid media, especially for the heating of used oil during its reprocessing by cracking distillation, includes at least one infrared irradiation element located in a vertical cracking vessel. The irradiation elements are separated from the oil to be heated by spaced infrared permeable tubes of quartz glass having cooled intermediate spaces therebetween. The spaced tubes allow the infrared energy to pass unobstracted into the vessel and the intermediate spaces therebetween prevent heat transfer by convection or conduction to the oil. The cracking of the used oil is thus carried out without the formation of undesirable deposits of bituminous substances within the vessel, and especially upon the irradiation elements.

  • Patent number: 3995298
    Abstract: An apparatus of small dimensions may be used to operate the water contained in the processing baths of automatic processing machines. The solid residue may be collected and sent to silver recovery plants, whereas the evaporated water serves to heat the drying station of the processing machine whereinafter it may be fed to the washing station. In so doing, a considerable amount of wash water is recovered and no chemical compounds are discharged to the sewer through which pollution of surface waters is practically eliminated.

  • Patent number: 3970511
    Abstract: Dilute solutions of corrosive products, such as sulphuric or phosphoric acid, are concentrated by pre-concentrating the dilute solution and then introducing the pre-concentrated solution into a tunnel in which it flows in a thin layer over successive cascades while being heated, preferably by indirect radiant heating. An installation for carrying out the process is also described.

  • Patent number: 3960725
    Abstract: Sludge containing metal hydroxide is first subject to a separation treatment where solid particles are removed, and then dewatered to obtain a greater concentration of the metal hydroxide. The dewatered sludge attains a thixotropic character whereupon it is applied to a carrier in a film-like manner. The film is heated and then sintered so as to achieve a metal oxide that is harmless and easily handable. The separation and dewatering steps of the process are carried out in a first apparatus having a suction drum surrounded by a filtering cloth that removes the water contained in the sludge and transfers it to a second apparatus having a rotating carrier for receiving on the circumference thereof the metal hydroxide in a film form, whereupon the film is heated during rotation of the carrier and sent to a sintering apparatus for conversion to a metal oxide in a granular or powder form.
