Title: Process for preparation of nylon-46 fiber
Inventor: PARK JONG-TAE
IPC: D01F6/60
Filed: 1991-12-05
Granted: 1993-11-30
Abstract: The method for melt-spinning the nylon-46  polymer  having  a repeat unit of more than 90 mol% of ?-NH-(CH2)4-NH-CO-(CH2)4-CO-?, and a melting  point  (MP)  of  more  than  285  deg.C  comprises: spinning  the  polymer  under  the  condition  that  the  relative viscosity of the polymer (RV), measured by 1 g/dl conc. of 96 wt.% of sulfuric acid solvent at 25 deg.C is 3.5-4.0, spinning temp. is MP+10 - MP+50 deg.C, and the starying time from the  molten  state in the extruder and just after the extrusion is 3.5-8.0 min.;  and passing the extruded filaments through the heater, whose length is 50-300 mm, and temperature is  controlled  at  T  (spinning  temp; deg.C) - T+50 deg.C, so that the extruded filaments  are  quenched and solidified.

Title: Method of signaling the time-out situation on real-time os
Inventor: CHON SONG-IK
IPC: G06F15/00
Filed: 1991-12-17
Granted: 1994-08-25
Abstract: The timeout signal transmitting and receiving method includes the steps of: initializing a timer; permitting an interrupt of the timer and performing a standby state; calling an interrupt service routine when the interrupt occurs; if there is a timeout transmitting/receiving request from the user, generating a periodic signal transmitting and receiving request with respect to a periodic signal, and generating the timeout signal with respect to a nonperiodic signal; and if the timeout signal transmitting request is received, processing the timeout transmitting request, thereby raising the reliability.

Title: Cold rolling oil with lubricous and clean property
Inventor: HAN SOK-YONG
IPC: C10M169/04
Filed: 1991-12-31
Granted: 1994-12-26
Abstract: The cold rolling oil is consists of animal/vegetable oil and aliphatic ester that a number of carbon of poly alcohol selected among penta erythriol and sorbitol and neopentyl glycol and trimethyol propane is 14-24. The extreme rolling oil is made from acid phosphoric ester and organosulforous compound of which formulation is 1:4 - 1:10 as weight ratio. The cold rolling oil of foil sheet is manufactured by adding 7-10 % of an extreme rolling oil based on weight of total rolling oil. After rolling, the foil sheet of high quality without stain can be made without electrolytic degreasing process.

Title: Regioselective substitutions in cyclodextrins
Inventor: PITHA JOSEF
IPC: C08B37/16
Filed: 1990-03-30
Granted: 1998-11-16
Abstract: A process for preparing regiospecifically hydroxyalkylated  alpha -, beta - or  gamma -cyclodextrins wherein the substitution is either directed toward hydroxyls 2 or 2,3 of the glucose units with little substitution on hydroxyl 6 or toward hydroxyls 6 and with little substitution on the secondary hydroxyls. The regiospecificity is obtained through the proper control of basicity of the reaction mixtures which are comprised of epoxide and cyclodextrins and a suitable solvent.
