Title: Continuous treatment with carbon di:oxide of residual lyes - resulting from the treatment of wood or straw
IPC: D21C11/04
Filed: 1977-08-04
Abstract: Improvements in chemical recovery of NaOH and thermal recovery of residual black lyes resulting from the mfr. of cellulose consists of continuously carbonating, at 70-85 degrees C and 0.5 kg/cm2, the residual lyes resulting from the treatment of wood or straw, previously concn. to 40% or 10-15% respectively. The lye, introduced continuously into the upper part of a tower, is dispersed and falls down the tower while O2, introduced at the lower part of the tower, rises. This gives, for the lye from the treatment of straw, a liq. in which silica and part of the lignin ppte. The ppte. is sepd. from the liq. in a rotary filter at ambient temp. and the lye passes to an evapn. stage. The mass of pptd. silica and lignin is treated with a 0.3% alkaline soln. of NaOH to dissolve the lignin, which is then added to the lyes passing to the evapn. stage. The improvements give a simpler evapn. process, an increase in the amt. of lignin obtd. a simpler carbonation appts. and a uniform yield, since the process is continuous.

Title: Internal combustion engine fuel control system
IPC: F02D41/24
Filed: 1978-06-22
Abstract: An internal combustion engine fuel ignition system has feedback from an exhaust gas composition transducer which operates effectively only at normal exhaust temperatures, the transducer having a very high impedance at low temperatures.
