A grinding shell (4), on which a sprial groove (4") is formed with the inclination of 6-20 deg., consists of twelve arcuate segments which are made of a high manganic steel and detachably mounted on the outer surface of the roller. The griding shell is axially divided by 120 deg and then radially divided into three pieces in order to permit an easy replacement. A belt conveyor or a beam structure with a hoister may be constructed over the griding mill to transport the lumpy material.

Title: Method of preparing celulose acetate fiber having high elongation
Inventor: HAN MIN-SHIK
IPC: D01F2/24
Filed: 1992-10-07
Granted: 1995-02-27
Abstract: The polyurethane chips are dissolved in dimethylformamide till the degree of density of dissolved polyurethane reaches to 12-18 wt.% and the solution is added to the raw spinning solution of acetate filament at the ratio of 8-15 wt.% on the basis of acetate. The mixed raw solution is heated to 62-68 deg.C before spinning and the spun filaments are dried by 85-92 deg.C hot wind to obtain an improved degree of extension as 15-25% compare with that of conventional cellulose acetate fiber.

Title: Fabrication method of an ornamental luminescent device
Inventor: KIM KI-CHOL
Filed: 1992-10-27
Granted: 1995-08-03
Abstract: The lighting apparatus for offering various kinds of lighting effects, has a lamp in the main body (2), a cover (1) having a flower pattern-formed wall for covering the main body. The method is composed of making a special-steel injection mould for offering a certain level of reflecting angle, transparency, and color; machining the mould with a diamond rasp file for maintaining the surface roughness of more than 10,000 mesh; machining the surface with a ceramic grind stone for maintaining the roughness of more than 3,000 mesh; machning the surface with the diamond compound material. The temperature of the mould is respectively +80 deg. at the cover (1) and +60 deg. at the main body (2).
