Patent JO-3125-B1 (JO)
Title: Selective Extraction of Potassium Chloride From Schoenite End Liquor Employing Tartaric Acid As Safe, Benign and Recyclable Extractant
Inventor: PAUL PARIMAL
Filed: 2013-10-03
Granted: 2017-09-20
Abstract: Although U S patent 8,182,784 teaches the recovery of potassium chloride form schoenite ‎end liquor (SEL) using dipicrylamine as extractant, and consequently simplifies the ‎recovery of sulphate of potash (SOP) from kainite mixed salt employing the scheme ‎disclosed in U S patent 7,041,268, the hazards associated with this extractant have ‎thwarted practical utilization of the invention. Many other extractants for potash recovery ‎have been disclosed in the prior art but none has been found suitable so for practical ‎exploitation. It is disclosed herein that the bitartrate ion, and particularly L-bitartrate, ‎precipitates out potassium bitartrate very efficiently from SEL with ca. 90% utilization of ‎the extractant. In contrast, recovery of potassium bi-tartrate from sea bittern directly is ‎relatively much lower. It is further disclosed that this precipitate can be treated with ‎magnesium hydroxide and magnesium chloride to throw out magnesium tartrate with ca. ‎‎90% recovery while yielding a nearly saturated solution of potassium chloride which can ‎be utilize for the reaction with schoenite to obtain SOP. It is further demonstrated that the ‎magnesium tartrate can be treated with an appropriate amount of aqueous HCI and added ‎into a subsequent batch of SEL to throw out potassium bitartrate once again which ‎demonstrates the recyclability of the extractant. The overall loss of tartrate over a cycle ‎was ca. 20% but the dissolved tartrate remaining in the K-depleted SEL and KCI solutions ‎can be precipitated out as calcium tartrate form which tartaric acid can be recovered by ‎known methods, curtailing thereby the Ioss of tartaric acid per kg of KCI to ‎‏>‏‎5 g. it is also ‎demonstrated that through a similar approach, seaweed sap containing ca. 4% KCI can be ‎concentrated to 20-22% KCI, with excellent utilization efficiency of tartaric acid, and this ‎solution can similarly be utilized for SOP preparation. Potassium salts bearing other anions ‎such as sulphate, nitrate. Phosphate and carbonate also be prepared from the isolated ‎potassium bitartrate.‎

This structure improves the frequency characteristics by suppressing the electric field which is generating from the electrodes.

Title: Process for de-inking of waste paper
Inventor: OM TAE-JIN
IPC: D21B1/32
Filed: 1989-11-07
Granted: 1992-12-12
Abstract: Regenerating process of waste  white  paper  (e.g.  no-carbon paper, copying  paper,  thermal  and  pressure  sensitive   paper comprises (1) beating waste paper to maintain the pump composition of waste paper to 8-15 % at 40-80  deg.C,  (2)  adding  a  natural polysaccharide and beating promoter into the beated pulp  and  (3) removing ink from pulp slurry by flotation treatment  method.  The polysaccharide is selected from algin, xylan and starch,  and  the foaming agent is para-nonyl phenol ethoxylate-based surfactant.

Title: Column repair circuit in ic
Inventor: LEE JONG-SOK
IPC: G11C29/04
Filed: 1990-05-18
Granted: 1993-05-06
Abstract: The column repair circuit selects data input/output using  an input/ output selection  circuit  to  eliminate  the  use  of  fuse required for the conventional method, so that a  repair  yield  of SRAM is increased. The circuit comprises an I/O selection unit for detecting false bit and bit bar line  corresponding  to  addresses which operate falsely and for replacing the bit and bit bar  lines by spare bit and bit bar lines and a decoder unit for sending data of selected bit and bit bar lines to data bit  and  data  bit  bar lines.

Title: Process for making fried pork meat coated by wheat powder
Inventor: PYON JONG-KWON
IPC: A23L13/00
Filed: 1990-06-25
Granted: 1992-09-26
Abstract: A instant sweet and sour pork is prepd. by (a) coating  meat, e.g. pork, fish meat, beef, with starch powder, soysauce  and  egg york, (b) frying the coated meat for 2-3 min. in the 180-200 deg.C edible oil for standing for 1-2 min. in atmos., (c)  re-frying  it for 1-2 min., drying, dehydrating  to  obtain  the  re-fryed  meat contg. 15 wt.% or  less  moisture,  (d)  fast-freezing  the  meat, sterilizing with UV light, packing and sterilizing at  high  temp. to obtain the fryed meat for sweet and sour pork, (e) packing  the prepd. fryed meat with sterilized  packed  sauce,  re-packing  and fast-freezing to obtain the final product.  The  obtd.  sweet  and sour pork is preserved for a long time.
