Patent DE-19740327-A1 (DE)
Title: Modular cross-flow filter for preparation of aqueous samples for analysis
IPC: B01D65/06
Filed: 1997-09-13
Abstract: In the preparation of aqueous samples containing particulate matter for testing, the fluid passes through a modular cross-flow filter with a supplementary suction shaft unit. The fluid is continually filtered and freed from particles. The fluid particle content is measured at the filter outlet. If the particle content exceeds a given threshold, fluid is redirected to a second clean filter while the first filter is regenerated. The filter assembly recognises indications of filter pore blockage and then automatically initiates the regeneration process.

Abstract: The invention relates to a first configuration of a method for increasing the growth of the soil micro-organism flora and for promoting the microbial digestion of a soil (substrate) containing organic matter, resulting in the subsequent reinforcement and promotion of healthy plant growth in said substrate. The method is characterised by the application of aqueous preparations containing a) ecologically compatible O/W type wetting agents with b) lipophilic saturated and/or olefinically unsaturated hydrocarbon radicals with aerobically and anaerobically decomposable organic compounds with a fatty structure as additional sources of C for promoting the growth of the micro-organism flora in conjunction with the application of c) support materials containing compounds of P and/or N which are oil-soluble at least in proportions and if desired, other macro- and/or micronutrients for plant growth, c) being applied at the same time as a) and b) after a set interval. The invention also relates to water-dilutable aqueous concentrates of the aforementioned components a), b) and c) and to the use of these mixtures of valuable materials for conditioning the soil, especially for a soil treatment which has the effects of accelerating rotting (mineralisation), improving the soil (improved soil ventilation, elimination of anaerobic areas of soil and similar) and especially for use as a vitalisation agent for strengthening plants with a preferably slow-release fertiliser effect.

Title: Fail-safe electro=pneumatic braking control for the rear-axle brakes of bus or tram
Inventor: BASSI MARCO
IPC: B60T8/30
Filed: 1997-11-13
Abstract: The relay valve (1) for the rear brakes of the vehicle has a supply line input (4) and a brake circuit output (13).

Title: Process to analyze, regulate and control a technical process
Inventor: TREITINGER BARBARA
IPC: G01N33/14
Filed: 1998-04-27
Abstract: Process to analyze, regulate and control a technical process uses measurements taken in gas phase dilutes with hot dry gas admitted through a venturi nozzle. Process to analyze, regulate and control a technical process with the objective of altering the composition of a solution or fluid comprises measuring the chemical substances in the gas phase above the solution or the suspension. Before analysis, the chemical substances are diluted with dry, hot gas. The dilution is effected using a venturi jet to extract the gas from a dry, heated gas holder having a pump, and a mixer section heated gas feed. The degree of dilution may be regulated and adapted to the requirements of the downstream gas analysis instrument. The chemical substances may be fed continually or intermittently to one or more gas analysis instruments. The instruments used may be flame ionization detectors or sensor arrays, and the information derived is used to regulate and control the main process, and may also be used as parameters and the data pool upon which the actions of self-teaching regulation and control systems are based.
