Title: Process and device for controlling single-phase or multiphase a.c. controllers.
Inventor: RUNGGALDIER DIETHARD
IPC: H02P27/02
Filed: 1990-01-19
Abstract: PCT No. PCT/DE90/00030 Sec. 371 Date Oct. 7, 1991 Sec. 102(e) Date Oct. 7, 1991 PCT Filed Jan. 19, 1990 PCT Pub. No. WO90/09701 PCT Pub. Date Aug. 23, 1990.In the open-loop control of A.C. power controllers through the phase-angle control of semiconductor valves (4), the chronological sequence of the firing signals (Z) for the semiconductor valves (4) is determined by reference signals (X). When the reference signals (X) fail for one or more periods, this chronological sequence is disturbed and damage to the load (2) to be controlled can result. Therefore, according to the invention, a method is provided whereby a safety firing signal (ZS) is always derived from the preceding firing signals (Z) when the expected reference signal (X) fails. In addition, a device for implementing the method is specified.

Title: Device for dispensing disinfectants.
Inventor: WERNER-BUSSE ALFRED
IPC: D06F39/02
Filed: 1990-05-17
Abstract: A device for dispensing disinfectants into washing liquors by means of a dispenser is to dispense the correct quantity of disinfectant in function of the dirt to be removed so that adequate but not excessive quantities of disinfectant are always released. To this end, an analytical cell determines, in particular continuously, the content of unused disinfectant in the washing liquor. A comparator connected to the analytical cell and to the dispenser compares the actual value obtained from the measurement system with a predetermined target value and actuates the dispenser when the the actual value falls below the target value. A sample preparation part which comprises a solids-retaining device with a dialysis membrane is arranged upstream of the analytical cell.

Abstract: Procédé et appareil permettant de réaliser une stratigraphie du sous-sol par radar. On émet dans le sol une onde électromagnétique et, en de nombreux endroits, des détecteurs enregistrent l'amplitude et le temps de propagation des ondes transmises, des ondes réfléchies et des ondes diffractées. Les signaux détectés sont traités par ordinateur pour donner des données très précises concernant la distribution des couches souterraines et la qualité du sol, qui servent alors de données stratigraphiques. Pour améliorer la précision des données, on utilise deux signaux pseudo-aléatoires ayant le même type de code mais dont les périodes sont légèrement différentes, ce qui permet d'obtenir un temps de mesure qui est plus long que le temps de propagation.

Abstract: An apparatus (14) for locating a source (12) of acoustic emission in a material (10) comprises four spaced transducers (16) coupled to the material (10). Each transducer (16) produces an output signal corresponding to a detected acoustic emission activity, and each output signal is amplified (18), rectified (20) and enveloped (22) before being supplied to a processor (24). 
     Artificially induced acoustic emission events, of known location are generated in the material (10). The processor (24) measures the times taken for each output signal corresponding to artificially induced acoustic emission events, to exceed two predetermined amplitudes from a datum time. A neural network analyses the measured times to exceed the predetermined amplitudes for the output signals corresponding to the artificially induced acoustic emission events and infers the mathematical relationship between values of time and location of acoustic emission event. 
     The times taken for each output signal, corresponding to acoustic emission events of unknown source location, to exceed two predetermined amplitudes from the datum are measured and are used to calculate the location of the unknown source with the mathematical relationship deduced by the neural network.
