Title: Method for producing pig iron
Inventor: VULETIC BOGDAN
IPC: C21B13/14
Filed: 2000-11-16
Granted: 2003-06-11
Abstract: In a method for producing pig iron, iron ore is reduced to sponge iron in a reduction shaft (1) and this sponge iron is then introduced into the head of a melting gasifier (3). In the latter, the sponge iron is melted with the aid of a gasification agent, also introduced into the head of the melting gasifier, and an oxygenous gas to form liquid pig iron, a reduction gas being produced simultaneously. The latter is led out of the head of the melting gasifier and supplied to the reduction shaft to reduce the iron oxide. The operation of the melting gasifier is controlled in such a way that a reduction gas is produced of such a composition and in such an amount that the sponge iron introduced into the melting gasifier has a high degree of metallisation. The operation of the melting gasifier is additionally controlled by iron oxide being introduced into it, said iron oxide reducing the degree of metallisation of the iron carriers introduced altogether into the melting gasifier in relation to that of the sponge iron.

Abstract: An apparatus is described for reducing coherent signal interference between at least two bit streams framed with a common clock signal. The apparatus includes an internal clock signal generated from the common clock signal and a Manchester encoder for encoding the internal clock signal with a unique signature. Also included is a logic AND-gate for combining one bit stream of the two bit streams with the encoded clock signal to produce an encoded output signal. When the encoded output signal is combined with another of the two bit streams during transmission, individual bits of the combined bit streams are identifiable at a receiving end. The receiving end decodes the combined bit streams and properly discriminates between ONEs and ZEROs.

Abstract: In a multi-carrier system, the carriers (f0 ... f511, f512 ... f1023, ..., f3584 ... f4095) are grouped in subsets (SUBSET1; SUBSET2; ...; SUBSET8). A constellation information transmitting arrangement (BiGi_TA), for instance located in the multi-carrier receiver (RX), produces for each carrier subset (SUBSET1; SUBSET2; ...; SUBSET8) a limited set of parameter values (B1, G1; B2, G2; ...; B8, G8) and transmits these sets of parameter values (B1, G1; B2, G2; ...; B8, G8) to a constellation information receiving arrangement (BiGi_RA), for instance located in the multi-carrier transmitter (TX). Through interpolation of the limited set of parameter values (B1, G1; B2, G2; ...; B8, G8) the latter constellation information receiving arrangement (BiGi_RA) determines the constellation where each carrier (f0 ... f511, f512 ... f1023, ..., f3584 ... f4095) of a carrier subset (SUBSET1; SUBSET2; ...; SUBSET8) will be modulated with.

Title: Detecting inclusions in transparent sheets
Inventor: STEVENS HARRIE JAMES
IPC: G01N15/02
Filed: 2001-03-29
Granted: 2004-01-11
Abstract: This light scattering technique for size measurement is based on the fact that an illuminated particle (inclusion) serves as a secondary radiation source in a manner which is related to its size. This technique allows for detection of inclusions in the interior of transparent solid media, such as bulk glass. When illuminated with a beam of monochromatic light such as a laser beam as the primary light source, the angular distribution of the scattered intensity originated from the inclusion in the micron to submicron range, is a function of intensity, wavelength and index of refraction. A lens and light trap block the primary light for reaching a detector. The light trap, however, allows the secondary scattered light to reach the detector.

Abstract: The present invention relates to a line inversion type liquid crystal display and a driving method thereof. A plurality of pixels arranged in a matrix, a plurality of data lines extending in a row direction and a plurality of gate lines extending in a column direction are disposed in a liquid crystal panel of the liquid crystal display. The pixel has a liquid crystal capacitor for performing display operation and a switching element turned on in response to a gate-on voltage to apply a data signal to the liquid crystal capacitor. A gate driver sequentially provides the gate-on pulses to the gate lines based on gate control signals from a timing controller, and a data driver sequentially applies the data signals with polarity inversion, corresponding to color signals from the timing controller based on the data control signal from the timing controller. The polarity of the data signals is inverted by the unit of at least two pixel rows. Since the width of the gate-on pulse applied to the first pixel row with polarity inversion is larger than that of other gate-on pulses, a charging ratio of the first pixel row with polarity inversion is larger than that of the other rows.
