IPC: B01D35/06
Filed: 1977-12-23
Abstract: PURPOSE:For improving magnetic material washing efficiency, to reduce the magnetic field of a filter medium almost to zero upon washing by transferring a magnetic blow-out circuit breaker for ferromagnetic material to the position where a  magnetizer is prevented to apply magnetic field on a said filter medium. CONSTITUTION:For washing an increased amount of the magnetic material captured and separated by a filter medium 1, a magnetic blow-out circuit breaker 5 is transferred the position where magnetization is prevented, and a pump 12 is actuated with valves 16-18 closed and valves 19-22 opened. Then, the back-washing water from a back-washing water tank 13 flows into said filter medium 1 through said valve 19, a pump 12, said valve 20 and a flow passage 2. At the same time, back-washing air is fed to said filter medium 1 through an air feed pipe 15 with an  air outlet 15a. Then, the magnetic field of said filter medium 1 is reduced almost to zero by said magnetic blow-out circuit breaker 5 since said magnetic field passes through said magnetic blow-out circuit breaker 5 from a magnetizer 4.

Filed: 1978-12-13
Abstract: PURPOSE:To obtain a low-cost time delay signal generator circuit featuring a long time limit by including the 1st and 2nd sag-tension oscillator circuits and then setting the turn-on voltage of the former than that of the latter. CONSTITUTION:The 1st sag-tension oscillator circuit is formed with SCR8 plus capacitor 6 and resistances 1-3; and SCR9 forms the 2nd sag-tension oscillator circuit along with capacitor 7 plus resistances 4 and 5. The capacity of capacitor 7 is set larger than that of capacitor 6. Now with application of voltage V from point P, capacitor 6 is charged, and the voltage at point (a) becomes V4 after the T0 second. Then SCR8 is turned on to charge capacitor 7, and capacitor 6 has the voltage drop. Thus the voltage at point (c) becomes to V1 along with that at point (a). The larger the capacity of capacitor 7 than that of capacitor 6, the closer becomes V1 and the larger the time delay effect becomes each. When the voltage of capacitor 6 lowers down to V1, SCR8 is turned off with capacitor 6 charged. And capacitor 7 is kept at V1, and capacitor 7 is boosted up to V2 as described before when capacitor 6 becomes to V4. This action is repeated until the operating voltage VO of SCR9 is exceeded after the T1 second, thus obtaining the time delay signal at point (d).
