Title: Method for extracting powder in powder preparing apparatus and method for extracting powder in gas phase polymerization reactor
Inventor: HATTORI NORIO
IPC: B01J4/00
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To enable powder to be extracted without clogging in a purge bin or valves by placing a purge bin downstream from a powder preparing apparatus and by placing a plurality of flow regulating valves downstream from the purge bin and by regulating each flow regulating valve to extract powder stepwise. SOLUTION: After the operation of a gas phase polymerization reactor, polyolefin powder is produced in fluidized bed reactor 1 and the powder is discharged to a extraction line 30. A change in the amount of the powder in fluidized bed reactor 1 is detected by a level indicator 45 and inputted regulator 46. The divergences of flow regulating valve 24 and 25 are controlled based on the command signal from a regulator 46, which regulates the discharge from a purge bin 22. This prevents the powder from accumulating in large quantities for a long time in the purge bin and enables the powder to constantly move to thereby prevent the progress of polymerization and aggregation of the powder.

Title: Valve operating portion of cracked gas producing apparatus
Inventor: ISOYAMA MITSUNORI
IPC: C10G9/00
Filed: 1988-03-30
Abstract: PURPOSE:To prevent backflow of cracked gas at the time of switching by providing an interlocking device having an interchange mechanism for permitting operation from a small opening of the second switching valve to full opening after the first switching valve is totally closed at the time of closing the first switching valve. CONSTITUTION:An interlocking device 6 includes an interchange mechanism 10 for permitting operation from a small opening of the second switching valve 5 to full opening after the first switching valve 3 is totally closed at the time of closing the first switching valve 3. By this arrangement, at the time of totally closing the first switching valve 3, the second switching valve 5 becomes a small opening, so that pressure on the upstream side of the first switching valve 3 in a cracked gas collecting path is kept from becoming lower than that on the downstream side. Accordingly, at the time of switching from a cracked gas producing process to an adhering carbon removing process, cracked gas is prevented from flowing back to the downstream side of the cracked gas collecting path.

Abstract: PURPOSE:To enable forward running even at the failed time by guiding line pressure to a drain port for adjusting pressure of a clutch control valve to suppress the pressure adjustment function of the clutch control valve when a brake control valve is placed at a brake releasing point. CONSTITUTION:When a B1 control valve 180, a C1 control valve 200, a linear solenoid valve 240 and a solenoid modulator valve 250 work normally, as long as the B1 control valve 180 is at a brake releasing point, line pressure PL is guided to a drain port 216 for adjusting pressure of the C1 control valve 200 through ports 190, 192.

Filed: 1984-04-19
Abstract: PURPOSE:To increase the effective length of an antenna by setting the element antennas even at inapplicable places and distributing the electronic power to plural antennas from active modules set at places where the element antennas are thinned. CONSTITUTION:Active modules b1-bn are connected to element antennas a1- an respectively. A phase shifter is provided together with a high output amplifier, a low noise amplifier and a transmission/reception switch. An electronic power distribution synthesizer (c) supplies and synthesizes the reception signals of antennas a1-an via active modules b1-bn.
