Title: Treatment of oil-containing electrolytic cleaning waste liquid
Inventor: HOKEZU HIROMICHI
IPC: C01B33/12
Filed: 1980-08-29
Abstract: PURPOSE: To treat oil-containing electrolytic cleaning waste liquid, economically, and to reuse the effective components, by introducing CO 2  gas into the liquid to effect the solid-liquid separation, concentrating and calcining the extracted liquid to recover Na 2 CO 3 , and calcining the residue to recover SiO 2 .  
     CONSTITUTION: In the electrolytic cleaning of steel, oil-containing waste liquid is extracted from the line as deterioration progresses, and bubbled with CO 2 -containing gas to precipitate the water-containing silicic acid (SiO 2 .nH 2 O) in the liquid according to the reaction of formula. The soild-liquid separation of the waste liquid with a centrifugal separator, etc. gives the extracted liquid (an aqueous solution of Na 2 CO 3 ) and the residue (oil+H 2 SiO 3 ). The extracted liquid is concentrated and the resulted precipitate is calcined at 300W400°C to recover the solid Na 2 CO 3 . The residue is calcined at ≥1,100°C, and SiO 2  is recovered. The recovered SiO 2  is about several mm in diameter, and can be reused as a part of the sintering raw material, and the recovered Na 2 CO 3  can be used as a part of the slagging agent for the preliminary treatment of molten iron discharged from a blast furnace.

Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To ensure communication with an opposite party without causing trouble on surrounding people in the case of conducting communication with the opposite party through the use of a mobile communication terminal. SOLUTION: While a transmitter side makes dialing to call a receiver side, the receiver side replies to the call. In the case that communication is made with a message between the transmitter side and the receiver side, at first a code number is entered. Then an input display section 3A and a message monitor section 3B confirm the input code number and routine text information corresponding to the code number and transmit the code number to the transmitter side. Upon the receipt of the code number at the transmitter side, corresponding routine text information is read from a message table in a ROM 2 and displayed on the message monitor section 3B.  The transmitter side confirms the message and transmits the reply to the message based on the code number so as to allow the receiver side and the transmitter side to make communication not by voice but by a routine text or illustration information.

Title: Method for detecting leakage of liquid transporting pipe
Inventor: SUDOU SUMIO
IPC: F17D5/02
Filed: 1983-07-04
Abstract: PURPOSE:To save labor and the number of persons in leakage detection, by generating pressure waves in a liquid at a position in a liquid transporting pipe, propagating the pressure waves to the leaking position of the pipe, and capturing the reflected waves generated at the leaking position. CONSTITUTION:Under the state an electromagnetic valve 3 is opened and part of liquid in a pipe 1 flows through a branch pipe 2, the electromagnetic valve 3 is closed. The flow into the branch pipe from the pipe 1 is suddenly stopped. Therefore pressure increase is yielded, and pressure waves are propagated in the pipe 1. The pressure is measured by a pressure detector 4. When the pressure waves reach a leaking position (a), reflected waves are generated. When the reflected waves reach the pressure detector 4, the pressure is measured. Based on the time difference between the passage of the outgoing waves of the pressure waves at the pressure detector and the passage of the reflected waves from the leaking position (a), the distance between the pressure detector 4 and the leaking position (a) can be found. Thus the saving of labor and the number of persons in the leakage detection can be accomplished.

Title: Back washable y type strainer
Inventor: NAGAO SHOZO
IPC: B01D29/62
Filed: 1993-04-26
Abstract: PURPOSE:To prevent a liquid from flowing out to the pump side of a nozzle tip and thereby prolong a replacement period by making controllable the rotation of a porous plate and a screen which are installed on a bottom plate provided on an axial pipe on a drain side from an area outside a strainer. CONSTITUTION:This back washable Y type strainer consists of a main nozzle system 6 formed monolithically with a tip, so that a pump is protected against damage by displacement of a nozzle tip. In addition, the nozzle 6 can be removed from a connection pipe A1 to a Y type strainer 8. Consequently, repair work and nozzle inspection are rendered easily. Further, if a maximum required number of baffle pates 5 are installed at a running water outlet, even when the nozzle tip 7 is of a screw type, the tip 7 does not flow and the pump is prevented from becoming damaged. Further, the frequency of using the porous plate 11 and the screen 12 on the drain side is less than a strainer output part. Therefore, one porous plate and one screen can be used twice by ensuring that the porous plate 11 and the screen 12 can rotate 180 deg. with a bottom plate 13 attached to the former. The strainer 8 can be repaired without removing a blind flange 15 in such a state that water is still circulating through the strainer.
