Title: Compact sewage treatment plant - combining aeration and final clarification tank and sludge thickener in one basin
Inventor: EGGELING HANS
IPC: C02F3/12
Filed: 1976-04-29
Abstract: A sewage treatment plant for small and medium sized communities has a long basin of trapezoidal section divided by partitions into an activated sludge section, a final clarification section and a sludge thickener/silo.

Title: Electronic photographic flash generating circuit - uses discharge lamp, triggering circuit, photodetector switch and thyristors
Inventor: ADAMS JUN JAMES R
IPC: G03B15/05
Filed: 1976-08-07
Abstract: An electronic photographic flash generating circuit which controls the duration of the flash consists basically of a gas discharge tube (FT1) in series with a thyristor (SC R1) both supplied from a high voltage condenser (C1) and triggered by a triggering circuit (16) of known type. A known light detection circuit (18) fires a second thyristor (SCR2) when the reflected light exceeds a chosen threshold and this extinguishes the discharge tube (FT1) and produces a light pulse lasting 1-2 seconds from a light emitting diode, to show that the sequence has occurred correctly. Two alternative forms of the circuit with transistor drives for the light emitting diode (LED1) include a separate supply in one case and the high voltage condenser supply (C1) in the other.
