Title: Rapid melting of stored solidified oil
Inventor: HATANO TOORU
IPC: B65D88/74
Filed: 1978-09-29
Abstract: PURPOSE: To prevent the environmental pollution by the charging and discharging of solidified oil in storage tank, and to improve the earthquake-resistance of the tank, by melting the crude or fuel oil stored in a tank from the part adjacent to the heater, and carrying out the rapid melting by the convection of the molten oil.  
     CONSTITUTION: When the heaters 2, 2', etc. are heated, the solidified oil near the heaters is molten by the heat conduction. Since the solidified oil 4' surrounded by the molten oil 5 has larger specific gravity than the molten oil, it decends to the direction of the white arrows. At the same time, the molten oil ascends to the direction of the small arrows, which increases the convection at the interface between the solid and the liquid, and strengthens the contact of the solidified oil to the surface of the heaters 2. The level of the oil is controlled by a thermometer, etc., and when the solidified oil 4' is completely molten, it is discharged from an outlet 3.

Title: Trimming treatment apparatus
Inventor: MATSUDA MASAHIRO
IPC: B29C37/02
Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To automatically cut a lug part in its lateral direction and to enhance workability by providing a lug part press means in the vicinity of a duct so as to press a lug part to a lug part cutting blade. SOLUTION: An air cylinder 20 is operated to allow a lug part cutting blade 21 to advance toward a lug part 14. Since a lug part press means 22 is operated to strongly press the lug part 14 to the lug part cutting blade 21 through a lug part press plate, the lug part 14 can be certainly cut in its lateral direction and it is unnecessary to cut the lug part 14 by the manual work of a worker and workability is enhanced. The lug part cutting blade 21 is attached to the opening part 15b of a duct 15. Since the lug part 14 cut by the lug part cutting blade 21 is drawn under negative pressure to be rapidly sucked into the duct 15, the lug part 14 is prevented from being wound around trimming roll 5. Work originally unnecessary such as the stop or re-rising of an apparatus is eliminated and workability is enhanced.
