Title: Measurement of damping of stray radio field measurement position - using known antenna factors and coupling correction factor determined by manufacturer at reference measurement position
Inventor: STECHER MANFRED DIPL ING
IPC: H04B17/345
Filed: 1992-10-09
Abstract: Two broadband antennas of the same type and mounted opposite each other at the measurement position act as a transmission and a reception antenna respectively. Their antenna factors AFt and Af are known and related according to AN = Vd - Vs - AFt - Af - DELTA AF . Void is the voltage at the receiver input for direct connection of both antenna cables via an adapter, VS the maximum voltage at the receiver input during variation of the receiver antenna height and DELTA Af a coupling correction factor. The measurement position damping is measured by the antenna manufacturer at a reference measurement position, and its difference from a desired value according to Table K1 of the CISPR standard for broadband antennas is determined. The deviation is used by purchasers as the coupling correction factor for all broadband antennas of the same type. USE/ADVANTAGE  - For measuring stray radio fields according to commercial standards, e.g. CISPR, ANSI, EN, and VDE. Influence of each different antenna type used on measurements is minimised.

Patent DE-4301116-A1 (DE)
Inventor: KNEER FRANZ XAVER
IPC: C05F17/00
Filed: 1993-01-18
Abstract: The invention concerns a microbiological method for the decomposition of organic wastes, the waste material being subjected to a composting process under aerobic conditions in a closed container to which air is supplied. Air is passed through the waste material at intervals, the spent air being drawn off together with the gaseous decomposition products. The length of the intervals between the air feed periods is controlled as a function of the lowest value of the O2 concentration measured in the spent air. The spent air which collects in the space above the composting material is preferably drawn off at the same time as air is supplied, or shortly afterwards, the O2 concentration being measured at this time. Alternatively, the O2 concentration in the space between the heap of waste and the container end wall or the O2 concentration of the gas in the heap of waste can be monitored.

Title: Underground tank truck with compressed-air emptying
Inventor: POHLE HELMUT
IPC: B65D90/50
Filed: 1993-03-24
Abstract: The liquids required underground can be advantageously taken underground in a protected frame and kept in intermediate storage there by an underground tank truck being used, the tank vessel of which is approved for an operating pressure of 5 bar and which, apart from the tank indicator and the filling nozzle, consists of an extraction device of riser pipe with extraction nozzle and a compressed-air connection nozzle. Since a widely extended compressed-air network is available underground, the tank vessel can be emptied quickly and safely even when the material or liquid is temperature-sensitive. Complete emptying of the tank vessel and thus a tank vessel which is always empty and is then refilled at the surface is thus available. Furthermore, accurate monitoring of the quantities extracted is possible. Corresponding positive control ensures that the tank vessel is always transported in the pressure-relieved state. <IMAGE>
