Title: Desaturating colours in TV receiver - using correction signal independent of luminance in mid range and varying outside that range
Inventor: BACHMANN PETER DIPL ING
IPC: H04N9/68
Filed: 1990-06-02
Abstract: In a ROM whose address inputs are fed with a luminance signal (Y") modified by extension of a middle part of the amplitude region, there is produced an auxiliary signal (S1) from that modified signal.  This signal, in the mid-region of the modified luminance signal is independent of it, and at upper and lower regions tends to the amplitude limits of the modified signal. The auxiliary signal is read out and multiplied by a first setting value (ST).  To the product (S2) there is added a second setting value (SCV) and the resultant control signal (S3) is used as a control signal.  A further ROM may hold the limit characteristics. ADVANTAGE - Enables independent setting of action point  and desaturation strength.

Title: HV pulse generating circuit - has magnetic pulse compression circuit with saturable main choke, and resetting circuit
Inventor: NAKAJIMA SHIN
IPC: H01F1/153
Filed: 1990-06-21
Abstract: The pulse generating circuit has a magnetic pulse compression circuit with a saturatable main choke (10), and a resetting circuit with a second saturable choke for the supply of the main choke with a pulsed current. The latter adjusts the magnetic flux density of the main choke to a preset, constant value at the start of a gate pulse. Pref. an overvoltage is generated in the saturatable main choke and supplied to the resetting circuit. Thus it is prevented to operate the second saturatable choke in a non-saturating range.  The pulsed current for magnetic flux density adjustment is applied to the main choke at the start of the gate pulse, when the  second choke is operated in its saturation range. USE/ADVANTAGE - For  vapour, excimer lasers etc., with high pulse repition rate and reliability.

Inventor: VULETIC BOGDAN
IPC: C02F9/00
Filed: 1990-10-11
Abstract: A process for the treatment of wash water from the gas scrubber of an iron ore reduction plant is described, the wash water being directly contacted in a gas scrubber with the crude gas, being taken off from the gas scrubber and, after precipitation of solids and cooling, being recycled to the gas scrubber. According to the invention this is accomplished in such a way that the wash water largely freed of solids in a thickener (1) is passed via a warm water tank (2) into a cooling tower (4), where the water is cooled and simultaneously a separation of dissolved carbon dioxide, an enrichment with oxygen, a conversion of the hydrogen carbonates of calcium and magnesium into carbonates and of the iron bicarbonate and iron sulphate into iron(III) hydroxide is carried out, and that this chemically destabilised wash water is, in a further thickener (6) arranged in series, freed of the remaining solids by the addition of flocculating and coagulating agents, chemically stabilised and passed through a cold water tank (7).

IPC: G06F15/18
Filed: 1991-06-24
Abstract: In many applications, the input signals in neuronal networks are beset by considerable uncertainties. For this reason, training data are often not representative enough for the test phase data. A method of processing uncertainties in neuronal networks is proposed to solve this problem. Modified input signals are calculated from the input signals of neurons by linearly combining the input signals with neutral values. The coefficients of this linear combination are measures of the certainty of the input signals.
