Patent ES-425557-A1 (ES)
Title: Sulfur dioxide scrubbing process
IPC: B01D53/50
Filed: 1974-04-22
Abstract: Sulfur dioxide is scrubbed from stack gases in an absorption device by a sodium-based aqueous scrubbing solution, a portion of which is subsequently and continuously regenerated outside the absorption apparatus by a causticizing reaction with slaked lime. The causticized solution is routed through a settling device wherefrom a portion of the aqueous sediment is returned to the causticizing zone to provide seed crystals which encourage the formation of larger sized solid particles also, a portion of the aqueous sediment from the settling device is continuously mechanically dewatered and then removed from the system. The liquid effluent solution from the settling device is passed to a solids-contacting and reaction device for mixing with sodium carbonate in order to reduce the calcium ion concentration and the solids content of the solution. The underflow of the solids-contacting device is conveyed back to the causticizing zone and the clarified overflow, i.e., the regenerated scrubbing liquor, is conveyed to the absorption apparatus.
Patent ES-426647-A1 (ES)
Title: Band limited fm detector
IPC: H03D3/00
Filed: 1974-05-24
Abstract: The output IF signal of an FM receiver is coupled to a coincidence gate, including a pair of transistors having common connected collectors and emitters, and also used to actuate a timer which provides a positive output pulse for each positive going excursion of the FM signal. The timer output is coupled to a second input of the coincidence gate and the gate provides an output when both of the applied signals are low. This signal is then applied to an inverter to provide a signal which has a relatively high duty cycle and which, after passing through a low pass filter, varies in direct proportion to the frequency of the IF signal.
