Title: Determining process conditions in gaseous or liq. media - by multiple sensor system using pattern recognition in an adaptive learning phase
Inventor: ADLER BERNHARD PROF DR
IPC: G01N21/49
Filed: 1992-08-21
Abstract: Identification of the condition of gaseous and liq. media is carried out by multi-sensor systems consisting of a heterogeneous sensor array, in which signals from the individual sensors, which are totally or partially constructively correlated, represent the overall condition of the media using pattern recognition methods such as fuzzy clustering or neural networks. The novelty is that (a) the individual sensors undertake a condition characterisation of the media even when the individual sensor signals do not allow indication of condition change; (b) the signals provide adequate representation of fuzzy conditions of the media using pattern recognition in an adaptive learning phase in which the number and type of individual sensors are ascertained in relation to the problem; (c) automatic trend recognition and correction are effected by application of elements of fuzzy logic to evaluation criteria consisting of max. rate of measurement change, the regularity of the measurement sequence, the parallel relation of the constructively correlated individual sensors, the angle (theta) between the instantaneous vector and the connecting line between the different conditions and the magnitude of the signals; and (d) pattern recognition methods and data interpretation methods are implemented in program control of the multi-sensor system. ADVANTAGE - Process condition differentiation is obtd. from a group of time-dependent target values by heuristic methods even when the stochastically fluctuating measurements are additionally falsified by various trends and the process conditions merge in a poorly defined manner.

Title: Method for connecting a winding outgoer of a transformer to a bushing conductor
Inventor: BAARZ KLAUS
IPC: H01F27/04
Filed: 1992-12-04
Abstract: It is intended to specify a method of this type, in the case of which no hand holes and assembly devices are required while being technologically simple, which can be carried out with a minimum of clamping points and in the case of which parts are prevented from being lost in the complete transformer and which allows the bushing to be replaced without lowering the oil level in the tank. This is achieved essentially in that, even during the assembly of the active part, at least one easily movable conductor is connected at one end to the winding outgoer, while its other end, which is still free, is equipped with a clamping device and is positioned on the winding outgoer in a stable position virtually at right angles under the subsequent bushing opening in the cover, and in that, once the active part has been introduced into the tank and the cover has been fitted, the movable connecting conductor is withdrawn via the cover, is conductively clamped to the bushing conductor and is pressed back again with the bushing, after which the bushing is connected to the cover in a liquid-tight manner. <IMAGE>

Patent DE-4312412-A1 (DE)
Title: Electric rod saw
Inventor: EGER WILHELM
IPC: B23D51/16
Filed: 1993-04-16
Abstract: The electric rod saw is used primarily for the care of trees and shrubs as well as for making protective cuts on account of a hazard to electric lines and traffic. In the known saws of this type the drive is at the top. Consequently, the saw is extremely tiring on account of the weight and is very cumbersome in the branches. In the novel rod saw, the head part (12) (Fig. 1) is deliberately kept very slim and without projecting parts in order to be able to operate unhindered in the tree branches and especially in the shrubs. The drive at the bottom also results in a favourable position of the centre of gravity for working free of fatigue to the greatest possible extent, especially in high branches. The sheet-metal housing is made of multi-profiled aluminium sheet in order to achieve high stability at the low weight. The "supporting rod" (1) (Fig. 2) permits safe use on high objects. The "oscillation stop" (3-6) (Fig. 2) also enables thin branches to be sawn. Extensions are possible with the "auxiliary extension" (18) (Fig. 1).   <IMAGE>
Patent DE-4312887-A1 (DE)
Title: Capacitive charge storing sensor e.g. chemical or biological substances - forms substance-contacting resonator for generating acoustic waves by transmitter and receiver interdigital structures and membrane separated by dielectric gap without mechanical connection.
Inventor: GIESLER THOMAS
IPC: H04R17/08
Filed: 1993-04-20
Abstract: The resonant circuit works with continuous acoustic waves, and the diaphragm acts as a sensor and receiver for the continuous plate waves. The prodn. of the acoustic plate waves in the transmitter transducer results only on the basis of electrostatic attractive force or excitation between the interdigital structures (4) of the transmitter transducer and the diaphragm (1). The output signal of the receiver transducer is decoupled capacitively. The oscillation amplitude of the continuous plate waves is measured by the capacitor formed by the interdigital structure (6) of the receiver transducer and the diaphragm. At the transmitter side, the diaphragm and the interdigital structures (4), and also on the receiver side, the diaphragm (1) and the interdigital structure (6), are separated from each other respectively by spacing in the form of a gap (3) and have no mechanical connection with each other. A dielectric forms the narrow gap, so that a movement of the diaphragm towards the interdigital structures, in the dielectric is possible. USE/ADVANTAGE - E.g. for process and water monitoring, pollution detector, exhaust emission monitoring and gas alarm. Measurement of gaseous and liquid media. Simple and cost effective acoustic-gravimetric sensor. Has very high sensitivity, permits use of thin diaphragm, position of sensor is determined with high resolution.

Title: Electric circuit arrangement for a monitoring light which indicates the operating state of a motor vehicle fog lamp
Inventor: BECK MARTIN DIPL ING
IPC: B60Q1/20
Filed: 1993-06-23
Abstract: An electric circuit arrangement for a monitoring light which indicates the operating state of a motor vehicle fog lamp operates in such a way that the monitoring light is switched on when the fog lamp is switched on and is switched off when the fog lamp is switched off. At the same time, the circuit arrangement has a circuit which is connected to a voltage as a result of the actuation of the ignition and the light switch (head lamp) and in which the fog lamp and a manual switch for activating it are connected in series, and a first subcircuit which is parallel to the circuit and in which the monitoring light is arranged. In the first subcircuit, connected in series with the monitoring lamp and the manual switch, a transistor is arranged whose base is connected to a control unit which is driven by the speed of the vehicle. As a result of such a design of a circuit arrangement for the monitoring light of a fog lamp, the possibility of the driver of the respective motor vehicle overlooking the monitoring light is virtually excluded. Thus, the technical conditions for the required compliance with the relevant legal regulations (StVo, traffic regulations) are substantially improved which simultaneously brings about an increase in safety for the occupants of the vehicle and other road users.
