Patent KR-820000736-B1 (KR)
Title: Assembling apparatus for slide fastener stringer
Inventor: TAKAHASHI K
IPC: A44B19/42
Filed: 1978-12-05
Granted: 1982-05-03
Abstract: Appts. for assembling a pair of slide fastener stringers includes a pair of pulling rollers(5,6) on a drive shaft(22) and contacted by a pair of auxiliary rollers to form two inlet nips, with a binder member(7) fixed at the inlet side to direct the stringers into the nips via guide grooves(11).  A respective probe is freely transversely movable to enter or withdraw from each groove to detect leading fastener elements and to retard the advancement of the leading stringer when its elements are contacted.  A differential transmission retards the roller advancing the leading stringer and simultaneously accelerates the other to longitudinally align mismatched rows of elements.

Title: Low pressure drop pulverizer throat
Inventor: KITTO JR JOHN B
IPC: B02C15/00
Filed: 1980-09-15
Granted: 1985-03-23
Abstract: The throat has an increased curvature radius at the inside and outside walls of the inlet and an increased curvature radius at the outside wall of the outlet, beyond standard engineering practice. The ratio of the radius of curvature of the inside and outside walls of the throat inlet and the outsdie wall of the throat outlet to the radial width of the throat is greater than 0.5 and less than 1.5. Each  vane has a top side with an air foil configuration, resulting in a gradual acceleration of the air flow from the throat inlet to an intermediate portion of the throat and a gradual deceleration of air flow from the intermediate portion to the throat outlet to minimize dribble of solid material downward through the throat.

Title: Apparatus of repetitiously marking continucly cast metallic strip material
Inventor: MARINGER ROBERT EDWARD
IPC: B22D11/00
Filed: 1981-05-04
Granted: 1984-12-21
Abstract: This invention relates to a method for repetitiously marking continuously cast metallic strip material. The material is cooled below the solidification temperature and passes through a nozzle at about 200-10,000 ft/min. The cast metallic strip is cast from a tundish of molten metal with a nozzle, which is placed within 0.12 inch from the surface of the casting material and provides the surface of the cast metallic strip with the initial marks. These marks are made in the surface of the continuously cast metallic strip and can be separated from the surface and converted from the cast metallic strip material. Molten metal is then poured onto the surface of the continuously cast metal.

Abstract: A method of and apparatus for obtaining digital expression of analog signals, in particular signals produced by «reading» (i.e., transducing) head-positioning information recorded on storage media, for example magnetic recording media. Head-positioning signals (36, 38) constitute signals bursts which are processed to obtain pulses whose width is dictated by the amplitude of the detected bursts, and the pulse width in each instance is expressed digitally by using the magnitude of the pulse to drive a counter-timer (61). The resulting count integrally embodies a digitized representation of the initial analog signal burst, which is directly available for further processing by digital means and for storage in digital memory apparatus.

Abstract: Curable copolymer containing the residues of copolymerisation of a fluoro monomer and of an acrylamide derivative, characterised in that:
 a) the fluoro monomer residues originate from the combination of vinylidene fluoride and of another fluoro monomer chosen from tetrafluoroethylene, chlorotrifluoroethylene, hexafluoropropene or of a mixture of at least two of the three monomers
 b) the acrylamide derivative residues originate from a compound of formula:

 with:
 n denoting a number from 0 to 8
 and x denoting a number from 0 to 3. 
<??>This curable copolymer is obtained by copolymerisation in solution in an organic solvent. In solution in a suitable solvent, this copolymer is employed in paints and varnishes.
