  • Patent number: 4717554
    Abstract: Fluorine or fluorine compounds dissolved at low concentrations in water are efficiently separated by use of hydrated rare earth oxides or insoluble hydrated rare earth salts, particularly hydrous rare earth fluorides or hydrous rare earth phosphates, as the adsorbent. By bringing fluorine dissolved water of pH 2-7 into contact with said adsorbent, fluorine is adsorbed on the adsorbent, and the adsorbed fluorine can be desorbed by contact with an alkali solution of pH 10 to 14 to regenrate said adsorbent. Also, by addition of a precipitating agent for fluorine to the desorbed solution, fluorine compounds can be separated by precipitation and the filtrate can be reused as the regenerating solution for the adsorbent.

  • Patent number: 4666883
    Abstract: Borate ions dissolved at low concentration in water are separated efficiently with the use of a hydroxide or hydrous oxide of a rare earth element as the adsorbent. By contacting a borate ion-containing water with the absorbent, borate ions are separated by adsorption, and the adsorbent having adsorbed borate ions is desorbed and the regenerated for reuse with a desorbing solution adjusted to pH about 2 to about 4 or pH about 12 to about 14.

  • Patent number: 4411793
    Abstract: In a process for the separation of elements by chromatography in which a front zone and a rear zone are present in front of and in rear of an adsorption band of elements, a high column efficiency can be attained by developing the adsorption band of elements without causing the entry of a main eluent having a relatively high concentration into the front zone. According to the present invention, elements can be separated into individual species not only in a high state of purity but also in a high state of concentration, so that the productivity of elements may be extremely increased as compared with that of conventional methods. In addition, according to the present invention, the amount of eluent employed is remarkably small as compared with that in conventional methods. Therefore, the present invention is very advantageous for the separation of elements from an industrial standpoint.

  • Patent number: 4240376
    Abstract: Aquatic animals can be kept in a living condition over a long period of time, without feeding them, by placing the aquatic animals, at a large density of more than 200 kg/m.sup.3 in environmental water; maintaining the temperature of the environmental water in a lowest possible range in which it is possible for the aquatic animals to exist; controlling the concentrations of ammonia compounds, water-soluble organic compounds and carbonic acid radical in the environmental water so that their levels do not exceed 20 ppm, 150 ppm and 1,000 ppm, respectively; and regulating the concentration of molecular oxygen dissolved in the environmental water so that it is 3 ppm or more.

  • Patent number: 3967373
    Abstract: A net-shaped outer blade for reciprocating type electric shaver having an improved new pattern of hair inlet holes is provided. In a metal lamina as the outer blade body, a number of hair inlet holes including slit-shaped and round-shaped types is formed between adjacent ones of a plurality of ribs which are spaced at a proper interval with continuously varying spacing. The length dimension of the hair inlet holes is varied thus depending on the varying spacing between the ribs, and their lengthwise direction is made the same with each other. The area of the respective holes is advantageously made substantially equal to one another.
