Title: Hydraulic antilock braking system esp. for motor vehicle - incorporates pressure-limiting valve to guard against prior locking of rear wheels after antilock protection failure
Inventor: ENGFER ORTWIN
IPC: B60T8/26
Filed: 1991-12-19
Abstract: In each hydraulic circuit (I,II) a pressure controller (40) is inserted upstream from the junction (12) of branches (13,15) to two wheel brake cylinders (5,7) via inlet valves (17,19). In parallel with a spring-biassed magnetic valve (42), a pressure-reducing valve (44) limits the pressure at the wheel brakes to fixed fraction of the pressure in the master cylinder (3). This avoids locking of the rear wheels before the front wheels become locked. USE/ADVANTAGE - Esp. in rear-wheel braking circuits, simple and compact pressure controller is easily integrated, e.g. into hydraulics of antilock protection arrangement.

Title: Identification set=up for coeffts. in fast Fourier transformation process - uses neural network to avoid need for sine and cosine functions to be calculated for each transformation
Inventor: GRENZENDORF DANIEL
IPC: G06N3/063
Filed: 1992-06-11
Abstract: A neural network approach is used for the rapid identification of coefficients in a fast Fourier transformation process. In particular, the process reduces the identification to a single routine. The serial input of a serial to parallel shift register receives the continuous signal and the parallel outputs are received by the neurons of the network. An output stage consists of a further shift register (2) generating a serial output. The output is defined as an + summation of fi. ga, n, 1 for values of n from i-o to m1. ADVANTAGE - Reduces time to determine Fourier coeffts.
Patent DE-4223427-A1 (DE)
Inventor: HEIDRICH KARL DR
IPC: G01N33/44
Filed: 1992-07-16
Abstract: The increased use of reusable bottles is linked with effective purification prior to refilling. Unfortunately, a considerable number of reusable containers are sent back with urine and hydrocarbon contamination (solvents/fuels). Detection of hydrocarbons is done using photoionization detectors or mass spectrometers, which permit a reliable selection. These measuring techniques are not applicable to urine, or only so with serious limitations. The method described here ensures that containers with residual urine can be reliably identified and sorted out. Depending on the age of the urine, ammonia (NH3) is released into the atmosphere, with detected quantities ranging from 3 to about 35 ppm in fresh or 14-day-old reference samples. The method used to measure these is based on the recognition of NH3, with the ammonia being burned catalytically or in a high-temperature converter to produce NO (nitrogen monoxide), which is then reacted with ozone. The energy released in this consequent reaction takes the form of light (chemiluminescence). This light is measured and provides a mesure of the ammonia present. The field of applications is that of monitoring sanitation with respect to reusable bottles and containers in the food and drink industries.

Title: Microprocessor-based control system for overlapping sheets in rotary printer - has two linear arrays of optical radiation emitters located above sheets, each array transverse to path of sheet, with corresponding detectors below, to generate transmitted intensity values for fuzzy logic unit
Inventor: KUGEL MATHIAS
IPC: B65H7/12
Filed: 1992-10-08
Abstract: Sheets of variable material paper are extracted from a stack and are laid on the table (1) of a rotary printer such that some overlap occurs. The detection of overlap and single sheet sections needed for the following process is achieved with the aid of two arrays of optical sensors (4',4) providing outputs dependent upon the paper density. Because of the varying material characteristics, a definite rule on which to base the decision is inappropriate. A set of knowledge-based rules implemented in fuzzy logic form are used as the basis of a microprocessor-controller (6). ADVANTAGE - Identifies overlap of sheets made of greatly-varying range of materials of sheet.

Inventor: STEIN RENE
IPC: C30B23/06
Filed: 1993-04-01
Abstract: A known method for preparing monocrystalline (single-crystal) SiC by sublimation involves heating, (by means of a first heating device (20), of the solid SiC stock (2) to a sublimation temperature (Ts) and subliming it and, by means of a second heating device (30), heating the crystallisation surface (3) to a crystallisation temperature (Tc).
