Abstract: PURPOSE:To improve the efficiency of continuous pickling and to reduce the size of a pickling equipment by jetting a liq. from stationary scale breakers under high pressure on the upper stream side of a pickling tank so as to break scale sticking to a material to be pickled in directions intersecting each other. CONSTITUTION:When a steel strip 1 is continuously pickled, two pairs of stationary jet scale breakers 7a, 7b and 8a, 8b are arranged on the upper stream side of a pickling tank (not shown). The two pairs are preferably fixed at about 20-70 deg. angle in the opposite directions. While the steel strip 1 is passed under about 2-10kg/mm<2> tension, a liq. such as water or an acid soln. is jetted from the scale breakers 7a... under about 20-100kg/cm<2> pressure. Liq. films of about 0.3-1.5mm thickness are formed on the surfaces of the steel strip 1 to protect the strip and scale sticking to the strip is broken by the pressure of the liq. At the same time, strains are produced in directions intersecting each other to crack the surface scale finely and quadrilaterally. Thus, the steel strip 1 is efficiently pickled.

Title: Regenerating method for dehumidifying adsorbent and discrimination device of regenerating time for executing said method
Inventor: SUNAZAKI SHINICHIROU
IPC: G01N25/56
Filed: 1980-05-29
Abstract: PURPOSE: To enable simple discrimination of time for completion of regeneration of adsorbent by utilizing the fact that when air for regeneration is blown into a layer of heated adsorbent, the time of temperature drop of the adsorbent becomes longer when remaining moisture in the adsorbent becomes fewer.  
     CONSTITUTION: Air to be dehumidified is sucked by a pump and passed to a container 2 from an inlet/outlet port 4. It is then dehumidified with an adsorbent 3, and dried air is discharged from an inlet/outlet port 5. When dehumidification is completed, the adsorbent 3 is heated by energizing a heater 6 to vaporize moisture contained in the adsorbent 3. When air for regeneration is blown into the container 2 from the inlet/outlet port 5 under this condition, the vapor is discharged from the inlet/outlet port 4 with air. In this case, if there is much remaining moisture in the adsorbent 3, the time of temperature drop of the adsorbent is short due to evaporation, and heating by the heater and blowing of air are repeated unitl the time of temperature drop becomes longer than the reference time for regeneration.

Title: Detection for harmful foreign matter of gas insulating apparatus
Inventor: NODA TERUO
IPC: G01N29/11
Filed: 1982-05-04
Abstract: PURPOSE:To perform a reliabile detection without the movement of harmful foreign matters to a low-electric field part or the dielectric breakdown due to their motion when an applied voltage is raised. CONSTITUTION:When an AC voltage is applied to an apparatus, a force F acts upon a foreign matter 11 in its electric field space against gravity, and the foreign matter 11 is floated up. When the applied voltage is an AC voltage (v) of a commercial frequency and the height of floating-up at a time t1 is denoted as h1 in this case, a height h2 of floating-up a time t2 is lower than the height h1 if the applied voltage is a high frequency voltage having the same crest value v0. The locus of the height h1 or h2 to a time (t) is a curve A in case of application of the commercial frequency voltage and is a curve B in case of application of the high frequency voltage, and the direction of the force F applied to the foreign matter is changed in every half cycle of the voltage waveform by the applied voltage, and therefore, the height h2 of floating-up of the foreign matter in case of application of the high frequency voltage is lower than the height h1 of floating-up in case of application of the commercial frequency voltage. Consequently, by making the applied voltage high-frequency, the voltage is raised to perform a safe and high-precision detection on a basis of ultrasonic waves generated by the motion of the foreign matter.
