Title: Feeder for welding wire
Inventor: YOSHIZUMI SHIYUUZOU
IPC: B23K9/12
Filed: 1978-02-14
Abstract: PURPOSE: To reduce the friction resistance and to lengthen the conduit liner, by installing the vibrating roller between the conduit liner for guiding the welding wire to the welding gun and the wire feed roller, on purpose to give a vibration perpendicularly to the direction of progress of the wire, and by giving the tension together with the pushing action to the wire.  
     CONSTITUTION: The wire 5 is held between the feed roller 2 and the push roller 3, and also, between vibrating rollers 7, 7, and is fed to the welding gun 6; while this wire 5 is being fed, a vibration is given to this wire 5 by the magnet 10 through the vibrating roller 7 approximately perpendicularly to the direction of wire feed. In accordance with this, a vibration perpendicular to the direction of progress of the wire 5 is given to the wire 5, which is also given the parallel vibration. At first, if the vibrating roller 7 shifts from the balanced condition (a), the wire 5 is placed under a condition (b) that the wire 5 is being pulled opposite to the direction of progress. Next, if the vibrating roller 7 returns to the balanced condition, the wire 5 comes to the pushed state; hereby, the friction resistance of the wire 5 is reduced, so that the length of the conduit wire can be lengthened.

IPC: B65G53/66
Filed: 1982-02-03
Abstract: PURPOSE:To continuously maintain a normal feed flow in a gas transport device of pulverized coal to a blast furnace tuyere part or the like, by calculating a deviation  from a target value only when an actual feed amount separated from a target value  uncontrolled band at each prescribed time is measured and suppressing an uncontinuous  feed flow of pulverized coal on the basis of said deviation. CONSTITUTION:A feed quantity of pulverized coal (Ta-Tc) in an applicable designated  tank is introduced to a pulverized coal feed controller 109 from a feed amout calculating device 108 by an applicable tank designated signal (S23a-S23c) of pulverized coal feed start from a controller CPU, if separated from an uncontrolled band + or -alpha of a  separately introduced target feed amount AO from a target feed amount (or blow  amount) setter 110, a deviation from the amount AO is calculated each time to correctively multiply a control sensitivity constant less than 1. A variable amount of tank internal pressure corresponding to this correction value is calculated to correctively  change a preset pressure of tank pressure. On the basis of the above, an opening of  pressure regulating valves 111a-111c is feedback controlled in such a manner that a  detected pressure value (P1-P3) from pressure detectors (Pa-Pc) becomes a correctively changed preset value of tank internal pressure, and a stably normal feed flow of  pulverized coal is continuously maintained.

Title: Prevention of diffusion of floating substance on water surface
Inventor: NAKANISHI YASUROU
IPC: E02B15/06
Filed: 1977-02-18
Abstract: PURPOSE: To prevent the diffusion of floating substances on water surface by a method in which a perforated tube is sunk under a water area with floating substances, and air is supplied continuously into the tube to form an air bubble zone under the water and at the same time to form a rising-up part on water surface above the tube.  
     CONSTITUTION: A tube 1 provided with a great number of desired diameter-holes bored at regular intervals is sunk under water 3 along the peripheral part of a water area where floating substances, e.g., dust, oil, etc., are present on the water surface. And, one end of the tube 1 is connected to a compressor 8 on a ship 11, for example, and then air is continuously supplied into the tube 1, whereupon the air blows out in the form of bubbles 4' from the holes 2 into the water to form an air bubble zone 4 consisting of ascending air bubble groups and at the same time to form a rising-up part 6 on the water surface. Thus, the diffusion of floating substances in water can be prevented by means of a diffusion-preventing wall 7 formed by the air bubble zone 4 and the rising-up part 6 on the water surface.
