Abstract: PCT No. PCT/EP98/03907 Sec. 371 Date Feb. 14, 2000 Sec. 102(e) Date Feb. 14, 2000 PCT Filed Jun. 26, 1998 PCT Pub. No. WO99/02568 PCT Pub. Date Jan. 21, 1999Samples of commercial cellulose having high crystallinity (>80%) and a degree of polymerization of approximately 1500 were pretreated enzymatically under various conditions with commercial endoglucanases, before the chemical conversion to substituted cellulose derivatives was carried out. The enzymatically pretreated cellulose samples exhibited a significantly higher substitution, up to 222% higher, in comparison with control samples which had been treated with buffer without enzyme. The increase in substitution during the chemical reaction could be observed in the presence of various amounts of alkali, but fell as the amounts of alkali decreased. At the same degree of substitution of the cellulose derivative, the use of cellulose pretreated with endoglucanase significantly reduced the amount of alkali required by 60%, as compared with the use of cellulose pretreated only with buffer. Furthermore, by reducing the amount of water used in the reaction mixture in the chemical reaction, it was possible further to increase the substitution of enzymatically pretreated cellulose.

Abstract: PURPOSE: An adsorbent for purification of livestock wastewater is provided which outstandingly treats nitrogen and phosphorous, does not cause secondary contamination, and in which filtering effects according to pH or temperature change of wastewater flown in are not varied, and a staircase type wastewater treatment system using the adsorbent is provided. CONSTITUTION: The staircase type wastewater treatment system for purification of livestock wastewater is characterized in that livestock wastewater is purified as it is sequentially passing through staircase type six stage adsorption tanks, chip shaped adsorbent coated with a composition comprising oyster shells, ocher, bentonite, charcoal powder and chitosan solution for adsorption reinforcement is received in first and second stage adsorption tanks so that filtering effect is obtained in the first stage while nitrogen compounds and floating matter are promptly adsorbed by reverse osmosis effect in the second stage, ball shaped adsorbent coated with a composition comprising oyster shells, ocher, bentonite and charcoal powder is received in the third to fifth stage adsorption tanks so that filtering effect is obtained in the third and fifth stages while remaining contaminants are easily adsorbed by self reverse osmosis effect in the fourth stage, and a filtering layer of hard charcoal, bamboo charcoal or activated carbon is formed in the lower inner part of the six stage adsorption tank while a filtering layer of washed veinstone or sand is supplied onto the above filtering layer in the state that the latter is stacked on the former so that livestock wastewater finally passes through the two layers.

Title: The high efficiency optical fiber cooling unit
Inventor: BAE SANG JUN
IPC: G02B6/00
Filed: 2001-03-06
Abstract: PURPOSE: A high-efficiency optical fiber cooling apparatus is provide to improve the cooling efficiency by keeping a cooling gas inside the cooling apparatus and increasing the density of the refrigerant gas. CONSTITUTION: A refrigerant gas pump(8) sprays a refrigerant gas from an upper portion of a cooling apparatus(4) toward an inside thereof. A refrigerant gas input unit(9) supplies the refrigerant gas from an external of the cooling apparatus(4) to the refrigerant gas pump(8). A diffuser(10) is composed of a space of expanded section so as to buffer an outflow of the refrigerant gas. A refrigerant gas supplying unit(6) for cooling the optical fiber by continuously supplying the refrigerant gas to an inside of the cooling apparatus(4), is formed on the center of a wall of the cooling apparatus(4).
