Patent KR-890001720-B1 (KR)
Title: A vacuum switch
Inventor: YASUOKKA KOICHI
IPC: H01H1/02
Filed: 1985-03-06
Granted: 1989-05-18
Abstract: This switch includes a vacuum vessel, a pair of electrodes within the vessel and two current carrying rods that pass from the electrodes to the outside of the vessel in an airtight manner. The method provides a contact piece on an outer surface of one of the electrodes, that is made of copper chromium alloy.  An electric current is flowed and interupted a predetermined number of times through the electrode to generate arcs that improve the surface condition of the contact piece.  A recrystallised layer of a predetermined thickness is produced on the piece.

Title: Crystallization apparatus for metal stripping
Inventor: UTDGINO GAZHIRO
IPC: B01D9/00
Filed: 1985-03-29
Granted: 1989-03-09
Abstract: The crystallizer is used to convert metal ions into metallic fluoride by mixing and contacting a metal ion containing organic solvent and a fluoride compound stripping solution, and to strip the metal ions.  A cooling zone is provided at the lower part of the crystallizer.  A forced circulating zone having at least one blowout nozzle is provided at the base of the cooling zone.  The forced circulating zone provides the release solution with swing flow.  The forced circulation zone prevents the precipated crystal from adhering to the wall of the crystallizer and from accumulating on the lower part. This allows continuous operation of the crystallizer.

Abstract: In a subscriber dialing number analysis method in a private electronic exchange, a number analysis program previously recognizes a next service function. The subscriber dialing number analysis method puts a "service step table" and a "number analysis middle data", copies a "number plan data" to a "number analysis middle data" when receiving one digit, and determines an analysis completion on the basis of the data. If the analysis is completed, the subscriber dialing number analysis method copies a "donation code" copied as a "middle data" to a "result data". If there is no digit input, the subscriber dialing number analysis method judges and performs a primary service function of a "service step table" and a secondary service function of "special service step table".

Inventor: JONG JIN-HYONG
IPC: E01D18/00
Filed: 1992-05-12
Granted: 1995-03-13
Abstract: The roller device for pushing heavy materials such as the concrete beam or steel beam for bridge structure, has a support frame (2), with a roller guide device on the column (11) of the base (1), and an endless track (3). The device comprises a bearing plate (5) at the frame (2); track guide rollers (6a)(6b) rotating on the bearing plates and having admission angle (θ) of the track (3); cover rings (46a)(46b) fitted on the shaft (42) of the roller (41), with cllarance (C) on the out or side of the roll bearing (43), which protect the roll bearing from penetration of the foreign material.
