Patent KR-850001754-B1 (KR)
Title: Mat and massage by the air
Inventor: MASSUMURA MISSUMA
IPC: A61H7/00
Filed: 1982-10-14
Granted: 1985-12-09
Abstract: This device is composed of a massage mat with some air pockets, an air supply source, admission tubes and exhaust tubes. The air pockets stand in a line and the air passages around the longitudinal, central part are narrow and so the amt. of compressed air in the passages is smaller than that in other places. The compressed air is provided or deflated in order. As air is supplied, the effect of centripetal wave massage or centrifugal wave massage is obtained. This device is used to treat acrofrigidus, insomnia, headache, etc.

Title: Method and apparatus for controlling motor-driven let-off motion for looms
Inventor: SAINEN TSUDOMU
IPC: H02P1/16
Filed: 1984-02-17
Granted: 1987-08-22
Abstract: Motor-driven let-off motion control gives increased tension detection and stabilizes restarting characteristics.  Control of motor-driven let-off motion comprises sampling the rippled variations in the tension of warp uarns each time the main shaft of a loom makes one revolution.  A composite PI(proportionalintegral) control mode is effected on the average of the sampled values for the quick detection of tension variations.  While the loom is at rest, the integrated values of the sampled tensions in the PI control mode are stored in preparation for achieving stable characteristies when the loom is to be set in motion again.  A PI output is kept at a certain ratio with respect to a fundamental speed for ideal tension compensation which will not be relatively varied even when the diameter of the warp cils is reduced.

Title: Device for twisting wires
Inventor: PETTER REMAN
IPC: B21F15/04
Filed: 1989-05-22
Granted: 1997-12-29
Abstract: The wire twisting device has a twisted bar (1) with a binding hook (4) which is set in rotation when a gripping part is pulled. The binding hook can be swivelled about an axis (5) and is held in the normal position by a locking slide (7) engaging in indentations (6) in the binding hook. When pulling the wire loop around the binding hook, a latch (13) is lifted, by which means the locking slide and thus the binding hook are unlocked and swivelled, by which means it can slide out of the wire loop. 
<??>A device of this type allows a constant and optimum twisting of the wire without the risk of it tearing and permits the automatic pulling out of the binding hook in the same pulling movement. 
<??>The formed wire for tying reinforced iron bars is constructed as a single wire hoop (17) with a welding point (23). By this means, on the one hand its manufacture is simplified and material is saved and, on the other hand, a firm tying is guaranteed.

Granted: 1998-10-15
Abstract: Abrasive particles and articles made from cubic boron nitride derived from coated hexagonal boron nitride which is substantially free of oxides and volatile contaminants. Polycrystalline CBN is prepared from HBN by removing oxide from the surface of HBN particles to form HBN particles having a substantially oxide-free surface. The HBN particles having a substantially oxide-free surface are coated with an agent which is capable of preventing re-oxidation of the surface of the HBN particles to form coated HBN particles in a substantially oxide-free state. The coated HBN particles in a substantially oxide-free state are then converted to a polycrystalline CBN by direct conversion of HBN to CBN. Coating agents include metals, metal carbides, metal nitrides and metal borides. A preferred coating agent is titanium carbide.
