Title: Deashing method in pretreatment of coal to be charged into coke oven
Inventor: NAKAGAWA ASAYUKI
IPC: C10B57/08
Filed: 1995-04-11
Abstract: PURPOSE: To attain a reduced ash content by sending a part of preheated coal to a combustion heating oven, introducing the coal into the lower part of a preheating tower together with combustion gas, preheating the coal by mixing the same with the dry coal present in the tower, and then removing coal particles not larger than a specific size. CONSTITUTION: Wet coal is sent from a hopper 1 to a drying tower 2, where the coal is dried to a water content of about 2-3% with a hot gas. The dry coal is separated from the carrier gas in a cyclone 3, and sent to a preheating tower 4. The gas separated is sent to a combustion heating oven 6 through a pipe 12 and heated. The preheated coal whose water content has been reduced to approximately 0% in the tower 4 is separated in a cyclone 5 from fine coal particles having a particle size of 250μm or smaller and from the carrier gas. The preheated coal is sent to a coke oven through a pipe 13. The carrier gas separated is circulated to the drying tower 2 through a pipe 9 and used for drying wet coal. 5-15wt.% of the preheated coal is taken out somewhere in the pipe 13, sent to the outlet of the oven 6, and sent to a lower part of the tower 4 together with a combustion gas. Thus, preheated coal reduced in ash content is obtained.

Title: Sound-proof device for stationary induction equipment
Inventor: SOKAI KATSUJI
IPC: H01F27/33
Filed: 1979-07-04
Abstract: PURPOSE:To suppress production of a standing wave against acoustic waves of all frequencies between a sound-shieldig plate and the outer wall surface of the stationary induction equipment by disposing obliquely the sound-shielding plate with respect to the outer wall surface of the stationary induction equipment. CONSTITUTION:The side wall 2b of a sound-shielding plate is disposed obliquely with respect to the outer box surface of a statioary induction equipment forming a vertical plane. Angles thetai and thetar of the shielding plate 2b with respect to the normal represent the incident angle and the reflecting angle of an acoustic wave with respect to the side wall 2b of the sound-shielding plate, and there is a relationship of a formula thetai=thetar. When the acoustic wave is accordingly incident obliquely with respect to the sound-shielding plate as shown, the propagating direction of the reflected sound becomes different from the route of the incident sound. Therefore, the propagating distance of the acoustic wave reaching the confronting surfaces becomes different every time the acoustic wave is reflected between the two wall surfaces having oblique angle with each other. It can largely suppress the production of a standing wave for the acoustic waves of all frequencies between the two wall surfaces without superimposing the original sound in phase with repetivively reflecting sounds by the above principle.

IPC: B23K9/12
Filed: 1978-07-14
Abstract: PURPOSE: To perform sensing or welding accurately, by defining the length of consumable electrode projecting from the torch, in the device using the welding torch commonly as the weld line sensor.  
     CONSTITUTION: For instance, the outer peripheral edge of a work mounting jig 105 is taken as the reference position, and a control box 400 changes a switch 204 to a power source for detection 206. Controlling the mounting jig and an arm 107 in the directions of X-, Y-, and Z-axes, a torch 109 is brought close to the reference position. The spark generated between a consumable electrode 209 at the tip of the torch and the mounting jig is detected by a current sensor 207, and the detected signal is inputted into the control box 400. Thus, the error of the length of the electrode projecting from the torch between the predetermined reference value and the actual value is obtained. According to this obtained difference, for instance, an electrode supply means 201 is controlled to send out the electrode, and the sending is stopped depending on the detection output of energization state. Thus, the projected length of the electrode is always kept constant, so that the sensing of weld line can be accurately done.
