[Also in Division C1] Hydrogen chloride gas is produced from aqueous hydrochloric acid, supplied through duct 8, by heating the acid in heat-exchanger 7 and passing it into vessel 18 where it is mixed with concentrated sulphuric acid from tower 9 so that the mixture contains at least 50%, preferably 70 to 90%, by weight H 2 SO 4 , which mixture flows as a film down the tubes of heater 17. The moist HCl gas, produced in vessel 18 and heater 17 is dried in tower 9 by countercurrent contact with concentrated sulphuric acid; and the gas is further dried by intense cooling in heat-exchanger 10. The dried gas is separated from condensate in separator 11. The mixture leaving heater 17 is submitted to flash evaporation in vessel 16 which is maintained under reduced pressure by vapour jet unit 12. The moist HCI vapours produced in vessel 16 flow to condenser 19, and the condensate is returned to the mixing vessel 18. The aqueous sulphuric acid, pumped from vessel 16 through duct 5, is concentrated; and the concentrated acid is returned to vessel 18 through duct 6, heat-exchanger 7, and drying tower 9. Those parts of the apparatus which are contacted with sulphuric acid are made of, or lined with, graphite.

Title: Resistance welder
Inventor: HASHIGUCHI ISAO
IPC: B23K11/31
Filed: 1980-01-11
Abstract: PURPOSE:To obtain a resistance welder that can evade magnetic work when welding a body to be welded, such as a reed switch, working magnetically, by providing a ferromagnetic body at a proper position in a loop surface formed of a loop-shaped current feed path for welding current. CONSTITUTION:A couple of ferromagnetic bodies A are arranged in the surface formed of a loop-shaped current feed path for the welding current of the resistance welder equipped with pressure mechanism head part 1 and current feed weld zone 2, i.e. loop path of base 5, conductive spring 6, upper supporter 7, upper electrode  3, a body to be welded, lower electrode 4, electrode rest 9, and lower supporter 8. As a result, magnetic flux generated with the welding current is absorbed by ferromagnetic bodies A effectively. Further, a magnetic field, particularly, in the vertical direction is shielded to decrease remarkably the intensity of the magnetic field at a welding part. Therefore, reed switch 11, for example, never works magnetically and force applied to switch 11 in welding can be excluded.

IPC: F28F21/00
Filed: 1981-01-08
Abstract: PURPOSE: To contrive to improve the moisture exchange efficiency and to reduce the gas shift rate by a method wherein porous member, which is treated weakly hydrophobically in advance with sizing agent, is impregnated with moisture absorbent and hydrophilic high polymer.  
     CONSTITUTION: The porous member serves as a partition plate 1 in the full heat exchange element. The porous member is treated at first with sizing agent so as to have weak hydrophobic property. After that, the member is dipped in the solution containing the moisture absorbent and hydrophilic high polymer and then picked up from the solution at the state the solution does not entirely pass into the interior of the porous member and dried, resulting in obtaining a moisture permeable and gas impermeable substance consisting of the porous member, the surface layer of which is formed with a dense hydroscopic thin film made of hydrophilic high polymer containing the moisture absorbent. In such a manner as mentioned above, the improvement of the moisture exchange efficiency and the reduction of the gas shift rate are contrived by using the moisture permeable and gas impermeable substance with the dense and hygroscopic thin layer on the surface layer of the porous member as the partition plate.
