Title: Gas prodn. for gas turbine operation - in combined gas and steam turbine power station
Inventor: LEITHNER REINHARD PROF DR TECH
IPC: F01K23/10
Filed: 1993-10-15
Abstract: Prodn. of gases for operating a gas turbine in a combined gas and steam turbine power station is carried out by almost completely combusting coal fines at above 1 bar pressure and above 1000 deg.C with (oxygen-enriched) air or pure oxygen opt. mixed with recirculate off-gas to produce a combustion gas consisting of SO2, H2O and opt. N2 (if air is used), this combustion gas being cleaned to remove dust (including alkali metal cpds. and opt. CO2 and NOx and then passed successively through a gas turbine and a waste heat boiler in which water is preheated, evapd. and superheated for operating a steam turbine with one or more pressure stages. The novelty is that the combustion gas (dirty gas, leaving the combustion chamber (1), is subjected to (i) cooling to 850-950 deg. C by heat transfer to the clean gas and by subsequent mixing with recirculated off-gas or a gas similar so that used in combustion, supplied by an injection pipe (30), (ii) cleaning to remove dust (including alkali metal cpds.,) e.g. in a cyclone or ceramic filter, and opt. SO2 and NOx, e.g. by addn. of lime dust (dry additive process) and ammonia (SNOP process), and (iii) reheating as clean gas to the gas turbine entry temp. by heat transfer from the dirty gas. ADVANTAGE - The process provides improved efficiency of electricity generation from coal by producing a higher clean gas temp. (1200-1400 deg.C), reducing heat losses, allowing the gas turbines to operate with a single flue and using the internal insulation of the pressure vessel and connection lines as a heat exchanger.

Patent DE-4419323-A1 (DE)
Title: Screw cap fitting machine
Inventor: MEWES GERHARD
IPC: B67B3/26
Filed: 1994-06-02
Abstract: The screw caps are fitted to the containers (1) by an axial drive to locate each cap on a container and with a servo drive screw action to secure the cap. The servo motor drive follows a preset program with an initial preset number of turns at a low torque and with a second phase in which the final torque is limited. In both cases the operations are monitored by measuring the motor current and the motor spindle position. During the cap securing phase the motor current is kept below a set level. If it rises above this level a warning is operated and the particular container is marked for subsequent resealing. The equipment has one motor for each sealing position, or one motor for two positions. In the latter case the two positions are synchronised to ensure that only one position at a time has the final sealing torque applied.

Title: Location of earth leakages in three-phase current
Inventor: ROTTER GERHARD
IPC: G01R31/08
Filed: 1994-08-18
Abstract: A process for the determination of an earth leakage in any chosen section of a three-phase circuit uses two earth leakage detectors (5,6), one of which is attached to a current alternator (4). Phased pulses form a pulse generator (2) produce current changes in the circuit. Permanent over-compensation for the earth leakage results from the inductance load current at the earth-leakage load coil (3) and the presence of leak to earth (13) is thereby shown. Simultaneously with the start of the phased pulse the voltage increases, but a current decrease in the circuit is established.
