Abstract: PURPOSE: To control adhesion of scale simply and economically by applying electric current to sea water supplied, through positive and negative electrodes installed on the sea water supply system of the conversion equipment of an immersed tube type vacuum evaporation system.  
     CONSTITUTION: Sea water 11 is supplied to the lower part of a casing 1 through a condensation tube 3 and a supply tube 8. Since the pressure in the casing is reduced, if warm water 10 is let flow in an evaporation heat transmission tube 2, sea water in contact with the tube 2 boils vigorously. The water vapor thus generated goes up to the upper part of the casing, cooled by the tube 3 and condenses. The condensed liquid 12 is collected in a condensing tray 4 and taken out from an outlet 5. Necessary number of pair of positive and negative electrodes 13, 14 are installed at a place where it comes in contact with the condensed sea water 11 near the tube 2, that is, the bottom of the casing. When weak current is applied between the electrode 13, 14, the sea water 11 is subjected to weak electrolysis and pH of the sea water near the electrode 14 becomes about 10. Then, hardly soluble flocks consisting of Mg(OH) 2 , CaCO 3  etc. are formed and condensed and adhesion to the tube 2 can be controlled.

Abstract: PURPOSE:To produce an arc spot at the end of an electrode axis during the starting, and prevent any rise of reignition voltage by winding an inner coil around the electrode axis, and winding an outer coil only around the outer end of the inner coil. CONSTITUTION:An electrode 3 for an emission tube of a metal halide lamp is formed by winding an inner coil 42 around the end of an electrode axis 40 made of a tungsten bar or the like, winding an outer coil 43 only around the outer end part of the inner coil 4, and making an easily dischargable matter such as sodium oxide to be held over the coils 42 and 43. Owing to the above constitution, the sectional area and the thermal capacity of the outer end of an electrode coil part 41 is larger than those of the inner end of the part 41, and the temperature of the inner end of the part 41 rises earlier than that of the outer end of the part 41. Consequently, an arc spot can be produced at the inner end of the electrode axis 40 during the starting, and any suppression of light can be prevented by preventing the rise of reignition voltage.

IPC: C21C5/56
Filed: 1983-03-04
Abstract: PURPOSE:To transfer smoothly the preliminarily reduced ore of a high temp. which is partially reduced in a preliminary reduction furnace by using double pipes consisting of an inside pipe of which the diameter can be changed by external pressure and an outside pipe which is held airtightly from the inside pipe for the transfer tube which conducts said ore into a vertical furnace. CONSTITUTION:A transfer pipe 13 consists of an inside pipe 14 and an outside pipe 15. The pipe 14 is cut over the entire length in the longitudinal direction thereof and, for example, cut ends 14a, 14b are tightly superposed to form an approximately circular section. Said pipe is aerially supported in the pipe 15 by means of an oscillating bar 16 and a spacer 18. The inside of the pipe 15 is airtightly maintained by a sealing material 19. An oscillator 17 is oscillated at prescribed intensity in the pipe 13 having such construction, by which the oscillation having the intensity conforming to said intensity can be applied through the bar 16 on the pipe 14. The stagnation and sintering of the ore powder in the pipe 13 are thus averted by oscillating adequately the pipe 13 or expanding and contracting the pipe 14 during transfer of the above-described ore or combining both, by which the smooth transfer of the powder is accomplished.
