Title: Production of ethylene/alpha-olefin copolymer
Inventor: ARAI KOICHI
IPC: C08F4/60
Filed: 1994-06-20
Abstract: PURPOSE:To prevent the degradation in metallocene catalyst activity in a process for copolymerizing ethylene with an alpha-olefin in the presence of the catalyst at high temp. and pressure by passing an unreacted gas after the polymn. through a fixed-bed adsorption column to remove impurities. CONSTITUTION:Ethylene and a 3C or higher alpha-olefin (e.g. propylene) are each compressed to a given polymn. pressure with a compressor, supplied together with a metallocene catalyst to a reactor, and copolymerized at high temp. and pressure. The resultant ethylene/alpha-olefin copolymer is separated from an unreacted gas with a separator and taken out. The gas is then introduced through a bottom inlet 1 into a fixed-bed adsorption column filled with an adsorbent 2 (e.g. zeolite) to adsorb and remove impurities contained in the gas, taken out through a top outlet 3, and transferred to the suction side of the compressor to be recycled.

Title: Arc drive type variable resistor
Inventor: OKAZAKI MASAYUKI
IPC: H02H9/02
Filed: 1989-05-30
Abstract: PURPOSE:To obtain an arc drive type variable resistor which can increase resistance at high speed by forming an environment of a space where the arc moves by a mixed gas of sulfur hexafluoride and other insulating gas. CONSTITUTION:The title item consists of two column-shaped resistors 1 and 1', main terminals 2 and 2', variable contacts 3 and 3' which are provided at both of them so that they can rotate and are in contact state normally, and a case 4 which stores them. In an arc drive type variable resistor, a mixed gas obtained by mixing sulfur hexafluoride, nitrogen, air, helium, hydrogen, etc., is used as an insulating gas. For example, by mixing the sulfur hexafluoride gas with volume ratio of 10% to the nitrogen, insulating resistance is enhanced by two times or more as compared with the nitrogen. However, arc running time becomes larger by approximately 20%. Thus, as compared with gas containing only sulfur hexafluoride gas, atmosphere with less reduction in insulating resistance can be formed without delaying the running time of arc, thus increasing the resistance rapidly.
