Title: Process for preparing chlorine by oxidation pf hydrogen chloride
Inventor: PARK KUN-YU
IPC: C01B7/04
Filed: 1993-09-08
Granted: 1996-06-28
Abstract: The catalyst for manufacturing chlorine is made by; (a) mixing the aqueous solution of CrO3 of 6 anions with ethanol; (b) heating and refluxing at above 90 deg.C; (c) calcinating at 400-500 deg.C for 3-10 hrs after seperating and drying the precipitate;(d) molding with 3-10 wt% stearic acid dissolved in chloroform added. Chlorine is prepared by reacting HCl and oxygen at the molar ratio of 4:1-4:4 at 350-375 deg.C under the catalyst Cr2O3.

Abstract: 본 발명은 엘리베이터의 도어 개폐 제어회로에 관한것으로, 이는 엘리베이터가 정지시 도어를 열림 대기 하고 있는 동안에 탑승자가 도어 닫힘 버튼을 누름으로써,엘리베이터 기동 빈도수가 증가하며, 전력소비가 증가하고, 도어 닫힘 버튼이 없을 경우 운전수부 운전과 같은 전용운전 모드가 안되는 종래기술의 문제점을 해소하고자 하는 것이다. 
     이에 따른 본 발명은 하나의 버튼구성과, 이 버튼을 탑승자가 누르면 내부 시켄스로 전용운전 모드 이외의 경우는 도어열림 버튼으로 인식하고, 전용운전 모드에서는 도어 닫힘 버튼으로 인식하여 불간섭 시간내에 도어 닫힘으로 인한 엘리베이터의 기동 빈도수를 줄일 수 있으므로 불필요한 전력소비를 줄이고, 또한 버튼 한개의 조작으로 운전수부 운전과 같은 전용운전 모드의 동작을 병행할수가 있는 성과가 있다.
