摘要:
An apparatus for entering sorting information has a plurality of sorting devices, a plurality of terminal devices, and a sorting-data distributing device. Each of the sorting devices photo-electrically recognizes sorting information in an image on a document and sorts the document using the recognized sorting information as sorting data. It supplies unrecognizable sorting data to the distributing device. Each of the terminal devices displays received unrecognized sorting data. An operator recognizes the sorting information corresponding to the displayed unrecognized sorting data and enters the recognized sorting information into the terminal device. The recognized sorting data is supplied to the distributing device. The distributing device is connected between the plurality of sorting devices and the plurality of terminal devices to receive and transfer the unrecognized sorting data to the one of the plurality of terminal devices that currently has the lowest load, and also to receive the recognized sorting data supplied from the terminal device and transfer the recognized sorting data to the sorting device which has supplied the unrecognized sorting data corresponding to the recognized sorting data. The distributing device includes a control unit, a plurality of input sections individually connected to the plurality of sorting devices, and a plurality of output sections individually connected to the plurality of terminal devices.
摘要:
A process for treating a waste water containing uranium and fluorine comprises a neutralizing precipitation step wherein slaked lime is added to the waste water containing uranium and fluorine and precipitate thus formed in separated and removed, and an adsorption step wherein supernatant from the neutralizing precipitation step is contacted with a chelating resin which can selectively adsorb fluorine ions and another chelating resin which can selectively adsorb uranyl ions to thereby adsorb and remove the fluorine and uranyl ions remaining in the supernatant. Eluates of the ions adsorbed by the chelating resins and waste liquors for washing and regeneration of these resins are returned to the neutralizing precipitation step. Prior to the neutralizing precipitation step, a decarbonation step may be provided for decomposing carbonate ions, if they are contained in the waste water to be treated.
摘要:
A resole resin in the form of microspherical particles whose surfaces are partly or entirely covered with a coating of a substantially water-insoluble inorganic salt and which are not larger than 500 .mu.m in size, and a process for producing such resole resin. The resole resin comprises solid particles that are highly heat reactive and can be stored in a stable manner for a prolonged period. The resin particles can be used with good results in all fields of applications (e.g., moldings, laminations and binders) where conventional phenolic resins are used.
摘要:
A process for producing microspherical cured phenolic resin particles having a particle diameter of not more than about 100 .mu.m, which comprises reacting a novolak resin, a phenol and an aldehyde in an aqueous medium in the presence of a basic catalyst and an emulsion stabilizer. Novel microspherical cured phenolic resin particles are produced by this process. The resin particles have excellent impact strength and mechanical properties, a sharp particle size distribution, and a low secondary agglomerate content, and because of these properties, are useful as an excellent modifier or filler for various plastics and rubbers.

摘要:
A spherical ion exchange resin composed of a phenolic resin and a metal hydroxide is disclosed. The metal hydroxide is enclosed and bound with the phenolic resin. A method for producing such an ion exchange resin and a method for selectively adsorbing ions using the same is also disclosed. The ion exchange resin is capable of efficiently recovering ions contained or dissolved in water in trace amounts and, hence, can be applied to any aqueous solution containing ions. For example, it can be used to recover useful substances from sea water and to purify waste waters from nonferrous refineries and nuclear power plants.

摘要:
A process for separately recovering uranium and hydrofluoric acid from a waste liquor containing uranium and fluorine comprises a neutralizing precipitation step wherein a magnesium compound is added to the waste liquor containing uranium and fluorine to form a precipitate and the thus formed precipitate is then separated; a distillation step wherein an aqueous solution of sulfuric acid is added to the precipitate separated in said neutralizing precipitation step to dissolve the precipitate and the thus formed solution is then distilled to recover hydrofluoric acid as a distillate; and a uranium recovery step wherein uranium is recovered from a residue produced by said distillation step.
