  • Patent number: 4515943
    Abstract: Novel highly pure and stable crystals of .beta.-nicotinamide-adenine-dinucleotide tetrahydrate (NAD) which is triclinic system and has a space group of P1 or P1 and lattice constants: a=8.861 .ANG., b=11.181 .ANG., c=8.630 .ANG., .alpha.=90.82.degree., .beta.=103.40.degree. and .gamma.=109.71.degree.. The crystalline NAD is prepared by cooling a 20 to 60 w/v % aqueous solution of amorphous NAD, which has preferably been treated with a porous weakly basic anion exchange resin to remove impurities, at a temperature of 0.degree. to 20.degree. C. When the crystalline NAD is added to the aqueous solution as seeds, the desired high pure crystalline NAD is prepared without conducting the treatment of amorphous NAD with the porous weakly basic anion exchange resin. A high pure amorphous NAD is obtained from the crystalline NAD by dissolving the crystalline NAD in water and subjecting the aqueous solution to freeze drying or precipitation with a solvent.

  • Patent number: 4431543
    Abstract: Phosphorus, nitrogen and BOD are removed from organic waste liquid containing the same by mixing the organic waste liquid with activated sludge which is substantially free of oxygen, nitric acid and nitrous acid and subjecting the mixture to the action of the activated sludge under anaerobic conditions which forms a mixture of a liquid rich in soluble phosphorus and an activated sludge low in phosphorus. The sludge and liquid are separated. A portion of the liquid is subjected to solid-liquid separation to form a liquid high in phosphorus and a sludge low in phosphorus. This latter sludge is, along with the other portion of the liquid and the sludge from which the liquid has been initially separated are mixed with oxygen, in the presence of nitric acid or nitrous acid and subjected to aerobic biological oxidation. This results in the formation of a liquid low in phosphorus and an activated sludge.

  • Patent number: 4393697
    Abstract: An air flow rate measuring apparatus having an air flow sensor and a temperature sensor which are disposed in a passage for intake air formed in the vicinity of a main air flow guide chamber in an internal combustion engine. The electric characteristics of the air flow sensor vary with the flow rate of air flowing by the sensors. The air flow sensor and temperature sensor have the same shape and the same construction. The temperature sensor is used to compensate the temperature of the air flow sensor so as to maintain the air flow sensor at a predetermined temperature. These sensors are arranged in the same plane that is at right angles to the direction in which said intake air flows. The sensors are extended parallel to each other in symmetrical relationship with respect to the center line in the above-mentioned plane. Conductor support pins to which the sensors are fixed are also arranged symmetrically with respect to the center line in the mentioned plane.
