The process for electrochemically purifying waste waters comprises passing the waste water through membrane electrolysis cells (2, 16), the separate draining of catholyte and anolyte and their subsequent blending, and the removal of the purified waste waters. According to the invention, the separately drained anolyte and catholyte are obtained in the membrane electrolysis cell (16) using soluble e...

In a ring network (1) messages sent from any one of a group of stations (3) to all the remainder include an acknowledgement field (ACK) holding a count preset to equal the number of expected destination stations. Each destination station that successfully receives the message acknowledges by decreasing the count by 1; acknowledgement is withheld if an error is detected in the message or the statio...

PURPOSE:To automatically combine U-shaped strands by individually disposing strands of different sizes which are independently retained at the prescribed positions, and then moving and combining the strands in the prescribed shape. CONSTITUTION:Strands which are formed in U shape are transferred one by one by a conveying material hanger 12 to a middle stocker 13. The stocker 13 independently retai...
