Title: Automatic paper feeder
Inventor: HABU TAKESHI
IPC: B65H3/46
Filed: 1980-12-29
Abstract: PURPOSE: To always feed a paper smoothly in a paper feeder including friction drive means for feeding sheet by sheet in contact wit the upper portion of a sheet stack by providing a humidifier for making humid a contact portion of the drive means with the sheet upper surface.  
     CONSTITUTION: In a paper feeder, a turning force of a roller 12a of a feed roller device 12 is transmitted to a pick roller 11 through a belt 13. The pick roller 11 is brought into pressure contact with a sheet surface 8a in such a manner that the frictional force causes the uppermost sheet 8b to be bent between the roller and a finger piece 10. Such a bending forces the sheet 8b to get over the finger piece 10 and be sent out. In such a feeder, humidifier 1 is disposed above the pick roller 11. The humidifer 1 comprises a reservoir 3 for storing humidifying liquid, a porous rubber member 4 mounted on the base of the reservoir, and a through hold 5 for communicating the reservoir 3 with the member 4. Thus, when the roller 11 retreates, the rubber member 4 is brought into pressure contact with the peripheral surface of the roller to supply humidifying liquid, resulting in that the pick roller 11 is kept humid.

Title: Devolatile extrusion method of thermoplastic polymer composition
Inventor: MORIYA MASAHIKO
IPC: B29C48/76
Filed: 1989-07-17
Abstract: PURPOSE:To prevent the polymer in the exit of volatile from being accompanied, while its separation effect is made large by a method in which a part or the whole of the heat amount necessary for the volatilization of the volatile is preliminarily given to polymer composition and the composition is caused to pass through the space formed with a cylinder and a screw at the speed equal to a prescribed speed or lower, whereby the volatile component is taken out. CONSTITUTION:The heating to be achieved in the time while the thermoplastic polymer composition containing volatile is transferred to a devolatile extrusion machine, is carried out until the temperature of said polymer composition reaches about 150-280 deg.C in pressurized state so as not to generate its volatilization. While said polymer composition approaches the feeding port 1 of said composition of the devolatile extrusion machine, a part of the volatile component is vaporized, and said composition becomes the mixture of gas and liquid or the mixture of gas, liquid and solid, and enters the cylinder 6 of the devolatile extrusion machine. The component having already volatilized and the component volatilized here go away from a rear vent 2 through the space formed with the cylinder 6 and a screw 5. The speed of the volatile in the gas passing this space is set at most 50m/sec. When the speed of the volatile exceeds this value, since the polymer is accompanied with said mixture from the rear vent, it is not preferable.
