Patent KR-900006689-B1 (KR)
Title: Method and apparatus for reducing core losses of grain-oriented silicon steel
Inventor: BENTODE JAMES G
IPC: H01F1/16
Filed: 1985-07-26
Granted: 1990-09-17
Abstract: The method is claimed for improving the core loss properties of grain orientated silicon steel by scribing across the steel width transverse to the rolling direction. The scribe lines are imprinted by rolling the steel between rollers, one of which is of steel with triangular projections spaced 2-10 mm apart, to scribe to a depth of 6x10 power -3 mm, the other of a material having shear modulus of elasticity of less than 500 psi for example rubber. The method is useful in processing silicon steel for use in the manufacture of power transformers generators and similar equipment.

Abstract: An apparatus for cutting and shaping a spherical body of a sticky material, comprising an assembly consisting of a number of rotary members (10) for collectively forming an enclosure at the center thereof to cut and shape the material passing through the enclosure. Each of the members has curved side surfaces (Y1, Y2) such that the enclosure is confined through the exposed part of one set of curved side surfaces of the members which pivotally swing to open and close the enclosure. The tip of each of the members follows the exposed curved side surface of the adjacent member to scrape off the material adhering thereto, and each of the members has a uniform thickness that is thick enough to preclude the member from wedging into the material and that decreases towards the tip thereof, so that substantially spherical products can be continuously produced without generating any difficulty caused by the material adhering to the cutting members or by the filling protruding through the coating even when processing very sticky, soft materials. <IMAGE>

Abstract: The two-dimensional discrete-cosine transformer includes first and second buffers for buffering input video signal data, first and second discrete-cosine transformers for two-dimensionally discrete-cosine-transforming the signals buffered by the first and second buffers, and first and second output buffers for buffering the signals transformed by the first and second discrete-cosine-transformers to output it to a data output line, thereby efficiently using a built-in data memory.

Granted: 1994-02-21
Abstract: The device transfers a strip in transversal direction in wet deflashing process for removing flash generated in performing epoxy resin-molding to a lead frame in assembling of semiconductors. The device comprises a first conveyor (20) having a width shorter than length of strip (7); a second conveyors (30) respectively arranged parallelly in opposite direction and having a gap between the conveyors wider than the length of the strip (7); a plurality of grip members (32), for sequentially gripping both ends of the strip (7) supplied from the conveyor (20), being in parallel with the conveyor (30).

Title: Ethylene polymers and process for manufacturing them in gas phase
Inventor: BAILLY JEAN-CLAUDE ANDRE
IPC: C08F4/60
Filed: 1991-08-03
Granted: 1999-06-01
Abstract: Process for the gas phase manufacture of ethylene polymers or ethylene copolymers containing, by weight, more than 80% of ethylene and less than 20% of one or more alpha-olefins containing from 3 to 12 carbon atoms, which comprises   (a) in a first stage, prepolymerizing a particular Ziegler-Natta type catalyst by bringing the said catalyst into contact with (i) at least one alpha-olefin and (ii) a cocatalyst (A) consisting of at least one organometallic compound and, (b) in a second stage, carrying out a gas phase polymerization reaction in a fluidised bed reactor by bringing the prepolymer into contact with ethylene or with a mixture comprising ethylene and at least one alpha-olefin containing from 3 to 12 carbon atoms, in such a proportion that the ethylene represents more than 80% of the total volume of the olefins to be polymerized. f
