Patent KR-950014843-B1 (KR)
Title: Process for the preparation of an impact-resistant thermoplastic resin
Inventor: HEIM PHILIP
IPC: C08F265/06
Filed: 1988-08-20
Granted: 1995-12-16
Abstract: In a first stage of this process, an elastomer latex is prepared in aqueous emulsion in the presence of a nonionic surface-active agent, from at least one ethylenically unsaturated monomer; then, in a second stage, at least one vinyl monomer, insoluble in water or poorly soluble in water, is added to the latex thus obtained. According to the invention, in the second stage at least one polymer or copolymer based on carboxylic acid units and capable of forming an interpolymer complex with the nonionic surface-active agent employed in the first stage is added, and then the pH of the mixture is lowered sufficiently to produce the transfer of the particles of the said latex into the said vinyl monomer(s); and, in a third stage, a suspension or bulk polymerisation is performed on the phase consisting of the said monomer(s) from the second stage and containing the transferred latex particles.

Abstract: The capacitance detecting circuit forecasts the  usable  time and the exhaustion degree of  capacitor  by  measuring  the  inner resistance of capacitor in the case of biasing the  initial  power source  to the  electronic  appartus.  The  inner  resistance  of capacitor is measurecd by intercepting the power source  supplying to the electronic apparatus for  a  period  of  time.  The  signal displaying the remain capacitance of capacitor is generated in the time of the first signal generation. The controller generates  the signal displaying the charging time of capacitor after  generating the second signal. The  displayer  displays  visually  the  remain capacitance of capacitor.

Abstract: The apparatus is for polishing the rubber belt on the paper perforator roller or a rubber roller wound around the circumference of the paper perforator roller so that it can make the perforator efficiently form holes in papers. The apparatus comprises a polisher(10) left/right transfered by a feeding roller and a lower roller(9); a adjustor(11) equipped on shafts(4',6') of a perforation roller(6); a sensor(12) controlling the adjustor(11) by sensing the perforation state of paper surface.

Title: High tenacity nylon-6 fiber
Inventor: LEE SANG-MIN
IPC: D01F6/60
Filed: 1992-07-27
Granted: 1994-12-20
Abstract: The high strength nylon-6 fiber having at least 10.0 g/d tenacity, at least 20.0 % breaking elongation, at most 7.0 % (150 deg.C X 30 min) dry shrinkage ratio, at least 0.056 ave. birefringence ratio, at least 0.45 orientation function in the amorphous region, at least 0.90 orientation function in the crystalline region and at least 40.0 % crystallization degree is produced by melt-spinning a polyamide polymer, cool-solidifying, drawing and taking up the polymer to obtain an undrawn yarn, drawing the yarn and relax heat-treating it at 40-150 deg.C. The nylon-6 fiber has a good heat and fatigue resistance, and is useful as a tyre cord and belt-reinforcing material.

Abstract: The sensing means(p1,t1) installed in the refrigerant emission part of the compressor(1) senses the emitted temperature and pressure of the refrigerant. The sensing means(p2,t2) installed in refrigerant intake part of the compressor(1) sense the temperature and pressure of the refrigerant. The controller(20) controls the circulation of the refrigerant and the whole cooling-warming function together, which is based on the temperature of the refrigerant perceived by the sensing means(p1,t1;p2,t2), maintains the over heating of the compressor(1) on the best temperature with controlling the electric expansion side(12), drives and controls the auxiliary heater(7).
