Inventor: QUARDERER G
IPC: B01J23/90
Filed: 1978-04-06
Granted: 1980-10-25
Abstract: In the hydrogenation of a slurry of coal in recycle oil in the presence of 110 ppm Mo(as emulsified aq. ammonium heptamolybdate), the bulk of the solids in the heavy-oil slurry was sepd. from the remainder of the slurry by heating the slurry to 110≰C and centrifuging the hot slurry. The underflow from centrifuge amounted to 9.53% of the total material fed to the centifuge. The centrifuge removed ash and iron from the underflow oil more efficiently than it removed Mo.

Abstract: The green light-emitting  fluorescent  material  composed  of (Y1-x-yGdxTby)3Al5O12 [0.05mole <= × <= 0.98mol; 0.07mol <= y <= 0.085mol  is produced by mixing 292.99-298.06 g of  yttrium  oxide (Y2O3), 38.062- 46.22 g of gadolinium  oxide  (GdO3),  28.04  g  of terbium oxide (TbO4) and 254.9 g of aluminium oxide  (Al2O3)  with magnesium fluoride  (MgF2),  barium  fluoride  (BaF2) or barium chloride (BaCl) as a flux, and firing  the  mixture  in  the  heat resistant container at 1450-1550 deg.C for 2-3 hr. The fluorescent material is useful for a braun tube of a color TV.

Abstract: On a two-bar knitting machine, the rows of stitches are alternately and successively formed by opposite zones of needles of the two bars, with the initial formation - by means of crossed needles of two first, spaced zones of needles - of at least one row of closure stitches (ACDB), followed by the formation of helical rows of stitches (Po and P) of gradually increasing dimensions to form shaped toes and then tubular portions for the legs (T); then the formation of at least one closure row in the zone (Z) of the crutch with crossed needles, and subsequently the formation of tubular fabric for the body (Co), with all the needles of the said first two zones and of the crutch zone, with final belt (MM-NN) <IMAGE>

Title: A spinning nozzle of synthetic filament for artificial furs
Inventor: KANG TAE-HYON
IPC: D01D4/02
Filed: 1990-03-06
Granted: 1992-10-01
Abstract: Spinneret plate (1) for making synthetic fiber for artificial fur has  orifices  (2),(3),(4)  with  different  cross  sectional shapes, e.g. hollow, irregular, that is star-like  or  cross-like, round or trilobal, aligned for the outer  part,  middle  part  and inner part respectively with the alignment number ratio 1:1-2:1-3. Monodenier and hollowness ratio of hollow  cross  sectional  fiber from extrusion orifice (2) are 30-60 denier, 10-30 % respectively. Monodenier and irregularity ration of irregular fiber from orifice (3) are 30-60 denier and 30-50 %, while  monodenier  of  round  or trilobal fiber from (4) is 1-5 denier.
