Title: Compressor
Inventor: KWON GI-BONG
IPC: F04B37/00
Filed: 1985-12-30
Granted: 1988-04-19
Abstract: The compressor is provided within its sealed casing with an eccentric rotary disc type drive means that enables to install a plurality of compression chambers within a cylinder and make discharges in as many times as the number of the compression chambers with one rotation of the crankshaft linked to a motor drive. The increase of the discharge amount results in reduction of discharge pulses for a better compression effect and enables to diversify the compressor into many other types without a change in volume of the sealed casing.

Granted: 1998-07-01
Abstract: Aromatic compounds are alkylated with C20-C1300 olefinic oligomers by contacting the oligomers and aromatic compounds with an acidic catalyst to produce novel alkylated aromatic hydrocarbon compositions useful as lubricant basestock and additives. The olefinic oligomers used as alkylating agents are prepared from 1-alkene oligomerization in contact with a reduced chromium oxide catalyst on silica support. In one embodiment, the aromatic compounds are alkylated with a mono-olefinic HVI-PAO dimer which is prepared as a product or by-product from 1-alkene oligomerization using reduced chromium oxide on solid support. The alkylated aromatic hydrocarbons retain the unique features of the alkylating olefinic oligomer and exhibit high viscosity index and low pour point. The novel alkylaromatic compositions show improved thermal stability; also, the compositions are useful as lubricant additives for improved antiwear properties, antioxidant and other properties.

Title: New plasmid peat 8 and method for preparation of alpha-antitrysin
Inventor: LEE MYONG-HUI
IPC: C12N15/57

Granted: 1993-12-24
Abstract: A genomic gene  encoding  of  human  alpha-1-antitrypsin  was cloned into a plasmid pET8C. E.coli BL21 (DE3) was transformed  by the recombinant plasmids and a transformant (KCTC 0009BP) carrying the recombinant plasmid pEAT8 was screened. The  transformant  was cultured in a M9ZB medium at 37 deg.C and IPTG (0.04 mM) was added to the culture at OD600 = 0.7. After incubation at 40 deg.C for 3 hrs, the cell pellet was recovered  by  centrifugation.  The  cell pellet was treated by sonication and  the  precipitate  containing alpha-1- antitrypsin   was   recovered   by   centrifugation.   The precipitate was dissolved in a buffer containing 8M area  and  the alpha-1-antitrypsin was purified by  DEAE-Sephacel  chromatography and Mono-Q chromatography of FPLC.

Title: Method for purification of korean type hcv antigen khcv ub-core 14 protein
Inventor: JO JUNG-MYONG
IPC: C12N15/51
Filed: 1991-08-06
Granted: 1993-12-24
Abstract: A recombinant strain E.  coli  W3110  (ATCC  68642)  carrying recombinant vector ptrpH-UB-CORE 14 was cultured in  a  LB  medium containing ampicillin (50 μg/ml) and tryptophan (200 μg/ml) for 12 hrs.  The  preculture  was  inoculated  to  M9  medium  containing ampicillin (40 μg/ml) and cultured for 6  hrs  farhter.  The  cell pellet was recovered by centrifugation and treated  with  lysozyme and sonication. The supernatant was  recovered  by  centrifugation and added with 8M urea. After stirring for  12  hrs  at  4  deg.C, sodium nitrate solution (final conc. 10 mM) was added and  stirred for 1 hr. The supernatant was recovered by centrifugation and  the specific antigen KHCV UB-CORE 14 was purified from the supernatant by CM-Sepharose ion-exchange chromatography, S-200 gel  filtration chromatography and Mono-S ion-exchange chromatography of FPLC.

Title: Apparatus and method for biological treatment of waste water
Inventor: KIM HAK-SONG
IPC: C02F3/00
Filed: 1991-08-16
Granted: 1994-09-28
Abstract: The toxic pollutant is decomposed by microbes with reactor installing hydrophobic tube of screw-shape. The apparatus comprises: hydrophobic tube (10) of screw-shape is installed by coiling on wall of reactor, and controlling feeding velocity of volatile toxic pollutant according to the volume of reservoir (12). The material of 10 is silicone or rubber.
