Title: Treatment of steelmaking dust
Inventor: MATSUI KOJI
IPC: C22B5/10
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To recover useful metals from a steelmaking dust collected from a waste gas and to treat an activated carbon-contg. material to which harmful substances in the waste gas are adsorbed by using the activated carbon-contg. material as a reducing agent to which harmful substances in the waste gas produced in the steelmaking process are adsorbed. SOLUTION: In the direct sucking line 31, the waste gas after preheating is treated in a combustion tower 32 to decompose and oxidize the oil content, CO or the like, and cooled in a cooler 33 to collect the steelmaking dust in a dust collecting device 34. An activated carbon is blown into the waste gas to adsorb dioxins or the like, which are collected as the activated carbon-contg. material by the dust collecting device 35 in the downstream side. Leaked gas from an arc furnace 11 and a preheating device 21 is connected to an indirect sucking line 41, and joined with the waste gas in the direct sucking line 31. The joined flow is introduced by a main sucking fan 42 into a dust collecting device 43. An activated carbon-contg. material and cokes are added to the steelmaking dust to produce pellets.  The pellets are introduced into a rotary furnace where metal oxides in the pellets is reduced into metals. At the same time, dioxins or the like in the activated carbon-contg. material are decomposed and changed into harmless.

Title: Slope distortion detecting method for warp-woof composition of silk cloth
Inventor: TSUCHIDA ISAMU
IPC: D06H3/12
Filed: 1978-10-09
Abstract: PURPOSE: To secure an assured and continuous detection for the slope distortion of the warp-woof composition of the silk cloth under transfer of the silk cloth by adding the light transmitter possessing a pair of bent light transmssion parts, the photoelectric element and others to the moire image measuring device.  
     CONSTITUTION: The light is projected to the surface of woven silk cloth 6 from light source 6 while cloth 6 is trnaferred toward arrow x and close to the front surface of measuring device 1. As a result, moire image 7 shifting toward arrow y is formed by development on the surface of device 1 according to the arrangement of the warp and woof of cloth 6. Image 7 is then projected to light transmitter 2, and the projection light passes through a pair of bent transmission parts A and B of transmitter 2 to be received at photoelectric elements 3 and 4 respectively. In this case, the slope distortion is detected for the warp and woof composition of cloth 6 by the difference of the degree of the brightness between the transmission light measured through elements 3 and 4. In such way, the slope distortion can be detected in an accurate and continuous way under transfer of the silk cloth.
