Title: Welding current control method for resistance welding machine
Inventor: WATANABE MASAO
IPC: B23K11/24
Filed: 1980-02-22
Abstract: PURPOSE: To decrease a change rate for the compensation of welding current against source voltage fluctuations by phase-controlling the welding current from a welding power source in such a manner as to be proportional to the multiplied voltage obtained from the differential voltage between a mean voltage detection value of an actual welding power source and a reference value of a welding power source voltage and the voltage corresponding to a welding current set value.  
     CONSTITUTION: The turbulent flow obtained by rectifying the source voltage v obtained from a welding power source 10 with a rectifier 12 is applied to a compared-difference amplifying integrator 26, which in turn compares and operates this with the predetermined reference voltage E 0  applied from a reference voltage setter 28 in terms of mean value. The integrator 26 is inputted with the voltage v and the voltage E 0  and forms the output voltage having the value corresponding to 2E 0 -V (effective value) through averaging and subtraction operation. Next, this output voltage is sent to a multiplier 30, which multiplies this by the voltage Ei corresponding to the welding current set value instructed by a welding current instructing circuit 32. On the other hand, the arcing pulse applied from a transfer pulse generator 34 arcs the phase control element of a switching circuit 22 whereby the phase controlling of the current fed from the power source 10 to a welding transformer 24 is accomplished.

Title: Condensation of organic sludge
Inventor: KITAGAWA TSUTOMU
IPC: C02F11/14
Filed: 1980-02-22
Abstract: PURPOSE: To facilitate floatation and condensation with a high efficiency, by adjusting sludge slurry at pH2W3, adding hydrogen peroxide to the sludge slurry, blending the mixture, and leaving the mixture to stand alone.  
     CONSTITUTION: At first, the pH value of sludge slurry is adjusted at pH4 or lower, preferably 2W3, by addition of an acid such as sulfuric acid or hydrochloric acid. This pH adjustment has a catalytic effect on the oxidation-reduction reaction by which hydrogen peroxide being added in the second step will be decomposed to oxygen and water. In the second step, hydrogen peroxide is added to the sludge slurry, and the mixture is blended. The addition amount of the hydrogen peroxide is 1.0% or more, preferably 1.0W5%, based on the solids. If the addition amount is lower than 1.0%, floatation and condensation effect would be poor. Thus, the hydrogen peroxide is effectively decomposed by the first and second steps. Air bubbles generated by the decomposition are very fine and effective in adhesions, grasping and separation of very fine solid grains.
