Patent DE-3828361-A1 (DE)
Title: Wind power station controlled as a function of the wind force and rotating about the vertical axis and having fixed and movable rotor blades
Inventor: SIEBERNS JOHANNES
IPC: F03D3/06
Filed: 1988-08-20
Abstract: Rotor having four or more fixed and as many movable rotor blades which are positioned vertically and rotate about the vertical axis. The speed control of the rotor takes place by intermittent fixing of the movable rotor blades which are curved in a circular shape and, in the closed state, surround the rotor with its fixed blades in a circular shape. The opening and closing of the movable blades takes place via rollers which run on an oblique plane mounted in the circular ring. The slewing ring having the blade-guide device is caused to follow by means of wind-guide apparatuses or via a servomotor. The intermittent fixing of individual or of all of the movable blades takes place via electromagnetically acting locking apparatuses which fix the movable blade on the lower and upper disc. The control of the switches takes place via centrifugal weights. Starting and tilting-out of the rotor takes place via electronically triggered switching pulses which are initiated by the wind-measuring wheel or via remote control.
Patent DE-3830901-A1 (DE)
Inventor: KOENIG WINFRIED DIPL ING DR
IPC: G01C21/22
Filed: 1988-09-10
Abstract: Locating and/or navigating systems for road vehicles must be set at certain location points, which often creates a problem, since the driver cannot stop his vehicle at these points, for example a crossroads, without incurring too great a risk due to the flow of traffic. It is therefore proposed to mark the setting point of the locating and/or navigating system by means of an indicator key and to define the said position later, when the road vehicle is out of the dangerous area of traffic, for example by entering the name of the street.
Patent DE-3830940-A1 (DE)
Title: Method for generating electrical energy (power)
Inventor: WESSEL RALF DIPL ING
IPC: F01K23/06
Filed: 1988-09-12
Abstract: The invention relates to a combined gas/steam process for generating electrical energy, in which the coal charge is gasified with oxygen. The raw (untreated) gas generated is cooled, cleaned and fed to the gas turbine combustion chamber of the combined process. The hot flue gas produced is expanded in the gas turbine and cooled in the waste heat steam generator and feed water preheater. The preponderant portion is further cooled in a gas cooler, and pressed, heated up in the raw gas cooler and reintroduced into the gas turbine combustion chamber. The quantity of flue gas corresponding to the mass of hot gas and oxygen supplied is expanded to ambient pressure and discharged. A part of the compressed flue gas is fed to the gassification reactor. The oxygen required for combustion is produced in an air separation system and introduced into the gas turbine combustion chamber together with the recirculated flue gas. The thermal energy of the gas turbine exhaust gas is used in a steam power plant by means of the waste heat steam generator and feed water preheater.

Title: Method for screening or filtering drinking water, service water and waste water
Inventor: SEEL KARL
IPC: B01D33/11
Filed: 1988-09-17
Abstract: Screening and filter media become chemically encrusted despite constant mechanical washing. The novel method for automatically initiated and automatically proceeding chemical cleaning of the filter medium is characterised in that, at predetermined intervals, the filter resistance is measured by means of a reference fluid and compared with the filter resistance of the clean filter medium under operational conditions. The cleaning process is repeated until the filter resistance has decreased to the preset minimum.

Title: Non-passable pipe repair - by packer and polyurethane resin injection
Inventor: JAEGER FRITZ
IPC: E03F3/06
Filed: 1989-04-22
Abstract: Non-passable channels and pipes for the supply of water and for sewage which have developed a leak, esp. at the junctions, and have created some erosion of the ground nearby, are repaired by the injection of PU resin between the two cuffs of a packer.  The two components of the resin are taken independently to the packer and are mixed by a counterflow mixer in it and injected.  The clamping cuffs are released after the solidification. The packer (7) has in its centre (8) a high-pressure counterflow mixer (16) and two clamping cuffs (9, 10).  A hose (17) surrounding both is made of a material to which PU resin cannot adhere.  It forms an inner cuff 818) which is controlled independently from the other cuffs.  Two twin lines 812, 13) circulate the two resin components separately to the mixer (26); another hose (20) supplies the compressed air for inflation and pressure test.  The ropes 811, 12) are used for manoeuvring. ADVANTAGE - This is a quick and reliable method of rapair without risk of subsequent erosion.
