Title: Manufacturing apparatus for synthetic hydrochloric acid
Inventor: INAGAWA TSUTOMU
IPC: F28D3/00
Filed: 1980-07-07
Abstract: PURPOSE: To improve the operational efficiency by attaching an absorption and cooling tower composed of multitube type heat exchangers each made of impermeable graphite to the bottom of a combustion tower and combining the exchangers in series with a connecting tube sheet in-between.  
     CONSTITUTION: An absorbing liq. fed from an inlet 4 flows down along the inner wall of a combustion tower 1 while absorbing part of synthetic gaseous hydrogen chloride sprayed from the nozzle 2 of a burner. The liq. is accmulated once at the bottom part of the tower, and it overflows into each V-notched pipe 10 and flows down along the inside of each heat exchanger tube 6 of the 1st-stage multitube type heat exchanger 5 of an absorption and cooling tower while wetting the wall. The liq. reaches a flow regulating cavity part 12, gathers temporarily and drops through the space continuously. As a result, when the liq. drops into each through hole of the 2nd-stage connecting tube sheet, the inside is covered with a uniform liq. film again, and the liq. flows down along the inside of each heat exchanger tube of the 2nd-stage multitube type heat exchanger 5' while wetting the wall normally.

Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To prevent registering dislocation during printing by providing an elastic member for urging a swing device in the reverse direction to the swing direction thus far in its both swing end limits. SOLUTION: During rotation in a swing start and end of a gripper claw device 25, a tortion bar 35 regulated in its rotation to the frame via a holder 40 by its one end is distorted in the rotation direction of the gripper claw device 25, distortion urging force in the reverse direction to the rotation direction of the gripper claw device 25 is accumulated to be maximum at the swing terminal end. Accordingly, the gripper claw device 25 is made slow in its speed by urging force as being near the swing terminal end, so that an axial torque applied on the swing shaft 2 is reduced, and the occurrence of oscillation is restrained at the time of stopping at the swing terminal end.  This is such that since the gripper claw device 25 turns around at the swing terminal end and an axial torque applied to the swing shaft 2 is reduced even in the swing start end at the insertion plate tip end part of a paper feeder for gripping the paper end by the gripper claw 31 of the gripper claw device 25, the occurrence of oscillation is restrained even at stoppage at the swing start end.
