Granted: 1985-11-06
Abstract: An audio signal on a 1MHz frequency modulated carrier is bandpass filtered, demodulated, and lowpass filtered to eliminate the carrier component.  Two rotating heads spaced at 180≰feed a preamplifier circuit via a circuit switching their outputs synchronously with rotation.  The signals are alternately joined to produce a continuous signal.  The demodulated audio feeds into a previous value holding circuit, storing a signal representing the present value immediately before the switching circuit selects a reproducing head output from one of the preamplifiers.

Title: Process for producing steel in a converter from pig iron and ferrous scrap
Inventor: KREIJGER PIETER J
IPC: C21C5/46
Filed: 1983-03-25
Granted: 1989-06-23
Abstract: The production of steel by the oxygen blowing of molten pig iron is improved by blowing oxygen into the melt via a first orifice while passing inert gas through an orifice in the base of a converter during at least part of the oxygen blowing cycle. During at least part of the time when oxygen is being blown in via the first orifice a second orifice is additionally used for oxygen blowing.  At least once during the oxygen blowing cycle carbon is introduced into the reaction from above.  The method allows enhanced quantities of scrap to be introduced into the melt without excessive losses of iron or manganese due to oxidation.

Title: Watch with lateral positioning means of the clockwork-movement in the case
Inventor: KAELIN LAURENT
IPC: G04B37/18
Filed: 1990-04-30
Granted: 1999-05-01
Abstract: The watch (1) in accordance with the invention comprises positioning means for the movement in the case. The positioning means comprise two blind holes (30) arranged in the case (6) and two centering elements (32), these latter having a first part driven into the blind holes and a second part (36) projecting from the case and cooperating with openings (38) provided in the movement.

Title: Dryer composition and producing method thereof
Inventor: PARK KI-SHIK
IPC: B01D53/28
Filed: 1990-05-12
Granted: 1992-09-09
Abstract: Drying agent is prepared by  (a)  granulating  the  secondary agglomerates which are mixed with  inorganic  sludge  produced  by surface treatment of aluminum, and fine powder of natural zeolite, and (b) heating or vaccum drying them at 120-300  deg.C  for  more than 1 hr. The mixing ratio of sluge to zeolite is 90:10, and  the drying agent consists of SiO2 60-80 wt.%, Al2O3 5.0-30 wt.%, Fe2O3 0.5-5.0 wt.%, CaO 1.0-5.0 wt.%, and MgO 0.5-5.0 wt.%.

Title: A metal coordination complex
Inventor: STEVENS JAMES C
IPC: C08F4/44
Filed: 1990-08-30
Granted: 1999-06-15
Abstract: One or more addition polymerizable monomers are polymerized by catalysts comprising a metal monocyclopentadienyl coordination complex and an activating cocatalyst to form novel polymers, including atactic amorphous poly(alpha-olefins), elastic polyethylenes and pseudo-random copolymers.

Abstract: 염화 폴리비닐 클로라이드(CPVC)는 폴리비닐 클로라이드(PVC)로부터 제조된다. 폴리비닐 알코올을 사용하여 제조된 PVC 로부터 만들어지는 저분자량 CPVC 화합물은 색깔을 띈다. 폴리 비닐 알코올대신 셀룰로즈 에테르의 존재하에 만들어진 PVC로부터 제조되는 저분자량 CPVC 화합물은 DE값이 0인 매우 담색의 화합물이다. 그러나 폴리비닐 알코올의 존재하에 만들어진 PVC 로부터 제조되는 화합물은 비교적 짙은 색을 가진다(DE 18.5). 염화비닐의 중합에서 폴리비닐 알코올은 메톡실 치환 및 4-35 의 히드록시프로필 치환을 갖는 히드록시프로필 메틸셀룰로즈 에테르로 대체될 수 있다.

Title: Automatic focus control method and circuit
Inventor: JANG SONG-IK
IPC: H04N5/225
Filed: 1991-02-21
Granted: 1994-08-31
Abstract: The automatically focusing method and circuit includes the steps of defining a focusing area from which a signal proportional with contrast is extracted, generating a sampling clock pulse for sampling a video signal corresponding to the focusing area, sampling the video signal with the pulse, generating digital difference signal, generating a digital weight signal by a nonlinear weight curve, taking the digital weight signal as a focusing value, and moving a focusing lens so that the focusing value becomes maximum, thereby enabling rapid and accurate focusing.
