Title: Production of polyethylene resin film by t-die process
Inventor: MATSUMOTO YOSHIO
IPC: B29C48/08
Filed: 1980-06-10
Abstract: PURPOSE:To reduce a resin loss which migh be caused by incontinent flow, by substituting a polyethylene resin in a T die with a polypropylene resin during the interruption of a membrane-producing operation. CONSTITUTION:A polyethylene resin in a T die is substituted with a polypropylene resin, when a membrane-producing operation is interrupted. Because the polypropylene resin contains a lot of tertiary carbon, the breakdown of molecular chains easily occurs at a high temperature, and the polypropylene resin reduces its molecular weight with heat deterioration. Consequently, the polypropylene resin has the characteristic that the viscosity of its melt is lowered at a high temperature, resulting in the enhancement of the fluidity. As a result, the polypropylene resin maintains the sufficient fluidity even when the interior of the die is kept at a high temperature during the interruption of a membrane-producing operation. Therefore, the substitution of the polypropylene resin in the die with the polyethylene resin can be facilitated well when the operation is restarted.

IPC: B65G53/16
Filed: 1978-06-29
Abstract: PURPOSE: To reduce the transfer speed of grains in a pneumatic grain carrier, by introducing gas in a spiral carrier tube and giving spinning movement to grains for upward transfer.  
     CONSTITUTION: Grains filled in a grain hopper 1 is sent through a feed tube 3 to a spiral carrier tube 4, being accompanied by carrier gas from a gas tube. The angle of inclination of the spiral tube 4 is preferably selected within a range of from 3 to 20 degrees, depending upon the conditions of grains to be carried.
