Title: Method for preserving food by refreezing
Inventor: MITSUDA HISATERU
IPC: A23L3/36
Filed: 1981-10-17
Granted: 1986-04-16
Abstract: Preservation of frozenfoods comprises; a) forming an ice capsule, in which the food, initially at room temp., is chilled in a freezing medium of - 80 to -100≰C to form a capsule within 15min; b) mildly chilling the food at -25 to -35≰C so that the temp. in the center of the food is 0≰C; c) then quickly chilling at -80 to -100≰C so that the temp. in the center becomes -6≰C or lower; d) storing the food at -18 to -20≰C until consumed. The ice capsule is pref. formed by blowing a freezing gas medium onto food sprayed with an aqueous soln. This method prevents the formation of large ice crystals and does not lead to structural fracture of the prod. over after six months.

Title: Protective capacity control system for a refrigeration system
Inventor: ZINSMEYER THOMAS M
IPC: F25B49/02
Filed: 1985-05-14
Granted: 1990-08-18
Abstract: The control system is for a refrigerator cooling a heattransfer fluid, reducing the output where this is excessive so as to reduce the discrepancy between the actual fluid temp. and a preset desired one. An input unit (19) supplies two different threshold temperatures, fed in manually, below the desired one to a processor (17). Where the actual temp. is between the desired one and the upper threshold one this maintains the refrigerator output. If it falls between the threshold values, the processor reduces refrigerator speed by a first amount, and if below the lower one by a second and greater amount.

Abstract: A self-tuning coin testing apparatus having a coin sensor circuit which produces an output signal indicative of a parameter characteristic of the coins which are tested by the coin sensor and a programmed microprocessor which stores an initial acceptance limit, determines whether the output signal from the coin sensor is indicative of a valid coin, stores a signal based on the output signal for each valid coin, calculates a statistical function based on the stored signal, and finally computes and stores a new acceptance limit based on the stored signals for a predetermined number of previously accepted coins. The statistical function, is preferably weighted so that it is based upon values for only a predetermined number of the most recently accepted coins so that a recent average is maintained.

Inventor: LEE SONG-HO
Filed: 1990-11-17
Granted: 1993-03-26
Abstract: The cosmetic material contains composite  pigment  which  has modified surface to enhance durability, adherance, waterproof, and stability of makeup. Pigment for cosmetic material is coated  with 0.1-5.0 wt.% anion substance  and  thereafter  with  0.1-6.0  wt.% hydrolized ginseng saponine hydroxypropyl trimonium chloride.  The above anion for primary coating layer is sodium or potassium  salt of citric acid, lactic acid, myristic acid, palmitic acid, stearic acid, amino acid, hydro acid and chitosan.
Patent KR-100223131-B1 (KR)
Title: Sustained-release drug dosage unit
Inventor: BRINKER DALE R
IPC: A61K31/505
Filed: 1990-11-29
Granted: 1999-10-15
Abstract: A sustained-release coating composition is described that contains an ethylcellulose and/or a methacrylic methylester together with a plasticizer and a detackifying agent. Sized drug granules are coated with this composition and then mixed with a polymeric composition containing at least one viscosity agent and formed into drug dosage units for the administration and sustained release of the drug in a patient. The sustained-release drug dosage units described produce a continuous, slow release of the drug at a therapeutically effective dosage level when administered to a patient.
