Title: Safety device for burner
Inventor: NAKAMURA KAZUHARU
IPC: F23M11/04
Filed: 1985-04-11
Abstract: PURPOSE:To enable both small flame and vertical flame to be detected by a set of sensors in a safety device for a burner utilizing a flame regulating action by a method wherein a second flame electrode is spaced apart from a flame electrode facing against the burner and connected in parallel with AC voltage. CONSTITUTION:When a flame is made small just after ignition or due to an irregular condition during ignition, the flame may not be reached to the electrodes 2 and 3 and a sufficient flame current may not be flowed in the flame electrodes 2 and 3, so that an alarm without flame may be generated. During a normal combustion, only the flame electrode 2 is present in the flame and the flame may not be reached to the second flame electrode 3. Thus, a less flame current is flowed and the AC voltage may cause an electric current to be flowed mainly through the flame electrode 2 so as to indicate a condition that the flame is present. When the flame is raised, the flame electrode 3 is also present in the flame and the flame electric current is flowed in the electrode 3, resulting in that the electric current caused by AC voltage is made as a mean value between the electrodes 2 and 3, the electric current flowing in the electrode 2 is decreased, a condition having no flame is indicated and then an alarm is generated. With this arrangement above, a set of sensors is sufficient for the operation.

Title: Vapor phase polymerization of olefin
Inventor: KATOU AKIFUMI
IPC: C08F2/00
Filed: 1981-05-23
Abstract: PURPOSE: To carry out the titled polymerization stably without formation of lumps or deposition of polymer on the wall, by performing the vapor-phase polymerization reaction under conditions in which the gas flow rate is high, the polymer entrained in the discharged gas is collected in a cyclone and the collected polymer is returned to the polymerization zone.  
     CONSTITUTION: Into the side of the upper portion of a tower type polymerizer 1 is supplied a catalyst from a pipe 11, and into the bottom of the tower is introduced at a high flow rate an olefin-containing gas consisting of a recirculated gas from a pipe 14 and a fresh gas from a pipe 15. The olefin-containing gas having passed a perforated plate 8 floates and fluidizes the olefin polymer and contacts with the catalyst to form a polymer. Here, the rate of gas rising through the tower 1 is at least ten times the minium rate for fluidization. The unreacted gas component discharges from the overhead 12 of the tower. The polymer entrained therein is collected in a cyclone 2 and returned to the polymerizer 1 through a rotary valve 3. The gas component leaving the cyclone is cooled in a cooler 4 and pressurized by a blower 5 and recirculated to the polymerizer 1. The amount of polymer in the polymerizer is kept constant by continuously withdrawing the polymer through valves 6 and 7.
