Patent DE-19505506-A1 (DE)
Title: Use of observer model for induction motor torque estimation
IPC: H02P21/20
Filed: 1995-02-10
Abstract: A hybrid state observer is employed with observer errors and measurements taken from the motor as inputs. The resultant torque error of the observer is used to train a neural net such as a radial basis function net (RBF) consisting of three layers of neurons. During operation of the motor, the neural net delivers a correction to the current value of torque computed by the observer, to improve the accuracy of prediction. Such a structure can be used where the torque must be estimated as precisely as possible but is not directly measurable.

Patent DE-19515595-A1 (DE)
Title: Method for sealing or shutting off pipeline using sensor and charge-activated balloon
Inventor: HUBERT KARL DR
IPC: F16K7/10
Filed: 1995-05-02
Abstract: The sensor (3) responds to any line pressure drop or surge by activating a propellant gas charge (2) via the control etc. mechanism (4) so as to inflate the balloon from its initially folded condition and so seal or close off the pipeline. The gas cartridge used as charge can be replaced by a gas or oil compressor. A non return valve is used to prevent the balloon penetrating the charge etc. during the inflation phase and an added outlet valve is used to bleed off the balloon pressure once the line fault etc. has been repaired or remedied. A net prevents the balloon sliding along towards the lower-pressure zone and is also used and possibly assisted by a tensile spring etc. to return the balloon to its original state once deflated. The sensor can be adjusted to particular threshold values etc. and the cartridge release mechanism can if need be blocked off either by hand or remotely.

Patent DE-19602881-A1 (DE)
Title: Method of supplying vehicle engine with cryo-fuel and air mixture
Inventor: MICHEL FRIEDEL
IPC: F02M21/06
Filed: 1996-01-29
Abstract: The method involves reducing the temperature of the air by means of the cryo-fuel. The boiling point of the cryo-fuel is below the ambient air.The fuel is stored in double-walled insulated tanks in liquid form, e.g. hydrogen at minus 250 degrees C or natural gas at minus 161 degrees C. The cryo-fuel is sent to the combustion chamber in gaseous form, mixed with air. The air required for combustion is cooled directly or indirectly by the cold potential of the liquid cryo-fuel., reducing it to the desired temperature, thus making the air denser and the power potential of the mixture entering the combustion chamber greater.

Patent DE-19606851-A1 (DE)
Title: Protecting system equipped with electronic circuit against electromagnetic interference
Inventor: STRENZKE HILMAR DR ING
IPC: G01R29/08
Filed: 1996-02-23
Abstract: The method of protection includes the comparison of the level of electromagnetic interference with a threshold value. When the threshold value is exceeded, a signal is transmitted, which facilitates a restoration of the system to a safe condition. The threshold value can be altered as required. Electromagnetic interference below the threshold value are not detected. A high frequency detector determines the electromagnetic interference. The interference is determined depending on their frequency. An optical or an acoustic signal can be transmitted. The signal can automatically make the system safe.
