Title: Treatment of chromium containing waste liquid
Inventor: TAKAGI TOSHIJI
IPC: C02F1/46
Filed: 1979-10-12
Abstract: PURPOSE: To let a conductive metal powder adsorb reduced trivalent chromium by a method wherein the conductive metal powder is filled in the cathode side of an electrolytic bath and a chromium-containing waste liquid is charged in the cathode side for treatment while electric current is passing.  
     CONSTITUTION: The conductive metal powder 6 such as iron or aluminum is filled in the cathode side 1 of the electrolytic bath. While electric current is passing across the cathode and anode sides, a chromium-containing waste liquid such as chromium plating solution is continuously charged in the cathode side. This causes hexavalent chromium in the waste liquid to be electrolyzed and reduced to trivalent chromium, which is adsorbed by the conductive metal powder 6. The process thus allows an easy and cheap continuous treatment of high-concentration, chromium-containing waste liquid, also permitting reutilization of formed sludge.

Abstract: PURPOSE:To prevent the malfunction of control over a car FM receiver in an intense or weak electric field, by extracting variation in signal meter voltage due to a multipath noise and obtaining a control signal. CONSTITUTION:A BPF is provided between a front end 2 and an IF detecting circuit 3 and as the degree of modulation increases, an AC voltage component increases at the signal memter voltage output of the circuit 3 to generate a multipath noise.

This amplitude-modulated component is made into a DC signal by an amplifier 12 and passed through an inverting circuit 13 to obtain the necessary control signal. This signal is applied to an electronic volume control 4, high-cutting controller 5, and separation controller 6 to control the signal linearly according to its level.
