Title: Method for chromaticgraphic separation of fructose/dextrosf solutione
Inventor: LEISER R
IPC: C13K3/00
Filed: 1978-01-24
Granted: 1982-05-11
Abstract: Tight packing of an adsorbent in a sepn. column with a chamber >=1.83 m wide comprises firstly mixing the adsorbent with an excess of a conc. reagent which causes the adsorbent to contract reversibly in its presence. The adsorbent is then packed in the contracted state, into the chamber of the sepn. column and effectively enclosed. The excess reagent is then removed to cause the adsorbent to swell so that the chamber becomes fully and uniformly packed with the adsorbent particles. The process is esp. useful for preparing technical scale ion exchange units contg. e.g. Ca salts of cross linked ring-sulphonated polystyrene esin adsorbents used in the sepn. of mixed fructose- and dextrose sugar solns.

Title: Process for the production of pig iron using cyclone
Inventor: PAPST GERO
IPC: C21B13/14
Filed: 1986-01-21
Granted: 1993-08-05
Abstract: A process for the production of pig iron from fine ore is described, in which initially the fine ore undergoes prereduction to a degree of metallization of preferably 65 to 75%. The sponge iron obtained is then melted down and under goes a final reduction. This process takes place in a melting cyclone 2, to which the sponge iron is supplied by means of a central opening 1 and into which are tangetially blown via a lateral opening 3 a carbon carrier, an oxygen-containing gas and optionally fluxes. As a result of the angular momentum produced, the sponge iron particles are deflected to the side and melted and finally reduced by the combustion gases of the carbon carrier. The molten iron collects in an iron bath 8. The gas produced in the melting cyclone is cooled from approximately 1500 DEG  C. to approximately 800 DEG  C. in a waste heat system 10, as well as by admixing cooling gas supplied via a line 11 and is then used for the prereduction of the iron ore.

Abstract: The method of manufacturing  anti-abrasive  protection  layer wherein, using a sputtering equipment having a sputtering chamber, a shutoff valve, a  cotrol  valve,  a  vacuum  pump,  a  substrate holder, and a target, a substrate  on  which  a  heating  resistor layer and wiring layer are formed  is  mounted  on  the  substrate holder, the shutoff valve conected to inert gas and active gas  is opened, the control valve connected to  inert  gas  is  opened  to inject inert gas, the substrate is grounded, RF power  is  applied to the target to form a first protection layer,  and  the  control valve connected to active gas is  gradually  opened  to  gradually inject active gas and to coat a second  protection  layer  on  the first protection layer, thereby simplifying manufacturing process.

Title: Ceramic materials
Inventor: PARK YONG-U
IPC: C04B35/26
Filed: 1990-07-14
Granted: 1995-01-27
Abstract: The ceramic material is composed of 5-94 wt.% of a high frequency loss material (A), 6-95 wt.% of a siliceous inorganic material (B), and 1-95 wt.% of a binder or 1-45 wt.% of an electroconductive material (C). The material (A) is pref. a crushed industrial waste i.e. magnetic, dielectric or electroconductive material. The ceramic material is produced by mixing 55 wt.% Mn-Zn ferrite powder with 45 wt.% cordierite powder, crushing the mixt. at about 1300 deg.C for 4 hr, adding 17 wt.% polypropylene resin to 83 wt.% crushed powder, and heat-blending the mixt. The ceramic material is used as an electromagnetic wave absorption material, heat storage material and heat generation material.
