Title: Data Segment Driven AFC Latch For Bi-Phase Stable Frequency Phase Locked Loop
Inventor: KRISHNAMURTHY GOPALAN
IPC: H04L7/00
Filed: 1995-03-31
Abstract: A dual mode AGC system for a television receiver in which data is in the form of symbols occurring at a fixed symbol rate.  The symbols are sent in successive data segments, each having a sync character.  Enablement of an AFC Defeat signal defines an initial interval during which the IF gain is maximum.  When the AFC Defeat signal becomes inactive, the receiver is operated in a non-coherent mode in which the gain of the IF amplifier is reduced incrementally whenever the IF signal exceeds a clipping level for a period of eight successive symbol clocks.  Upon a segment synclock condition occurring, a normal coherent mode is entered in which the AGC responds to a signal characteristic, i.e. data segment sync. The rate of gain change available in the non-coherent AGC mode is much greater than that in the normal coherent AGC mode.

Title: Fuel-cell system and method for operating a fuel-cell system
Inventor: LEHMEIER JUERGEN
IPC: H01M8/04007
Filed: 1995-10-06
Abstract: It is current pratice in a high-temperature fuel cell plants to divide the cathode exhaust gas in particular into two partial streams, one of which is recirculated into the cathodes and the other used for heating, in which branching takes place by relatively sophisticated technical means directly a the gas outlets at about the operating temperature of the fuel cells. In order to simplify these means, all the cathode exhaust gas is to be taken via a heat exchanger to a branch with two partial lines, in which the first partial line opens into the cathodes via an air-mixing position and the heat exchanger and the second opens into means for raising the temperature. Thus the branching of the hot cathode exhaust gas is avoided and the heat of all the cathode exhaust gas is used to heat the partial cathode exhaust gas flow taken back into the cathodes. The invention is applicable especially and preferably to fuel cells with an operating temperature of over 600 ~C. Such fuel cells are carbonate melt and solid electrolyte types.
