Inventor: KLAAS WILFRIED ING GRAD
IPC: H02J9/06
Filed: 1990-05-19
Abstract: The invention relates to a process and an arrangement for central monitoring of the operation of lamps which are connected in parallel via power supply lines, each lamp being allocated an interrogation circuit, to confirm the lamp operation, and a coded address, and a central monitoring unit using the addresses to initiate an interrogation of the lamp operation. In order to achieve a minimum installation cost and to prevent the possibility of connection errors, it is proposed with the invention to supply a high-frequency carrier signal in the supply line in order to interrogate the lamp status, which carrier signal is used to transmit the addresses by modulation using audio-frequency pulses. The report on the lamp status preferably takes place by means of a current load on the carrier frequency transmitter. An arrangement is additionally proposed, in which the monitoring devices (18) on the lamp side are installed together with an electronic ballast unit (19) in the screw or plug base of a fluorescent lamp (20). <IMAGE>

Inventor: WEBER RALPH
IPC: C21B13/00
Filed: 1991-03-14
Abstract: The invention discloses a process and a device for producing liquid metal (4) from fine metal oxide particles.

Patent DE-4109019-A1 (DE)
Inventor: WIDMANN FRIEDRICH
IPC: H04J14/02
Filed: 1991-03-20
Abstract: 2.1 It is known to combine electrical signals of a device for modulation and conversion, which have two electro-optical transducers and a modulation device. 2.2 In an arrangement for combining various electrical signals, the economic and technical expenditure can be considerably reduced if an electro-optical modulator (41) is used as device for modulation and conversion (40). This not only reduces the expenditure but, when several cascaded electro-optical modulators are used, only one carrier frequency is needed so that there cannot be any mutual influencing of various carrier frequencies as in the known arrangement. 2.3 The arrangement is particularly applicable to tunnel radio. 3. The drawing shows an electro-optical modulator which is used as device for modulation and conversion. <IMAGE>

Title: Dynamic correction of measurement errors in polymeric moisture sensors - by calculating correction factor from long term sorption behaviour of the sensor
Inventor: VOIGT JUERGEN DIPL PHYS
IPC: G01N33/00
Filed: 1991-04-09
Abstract: Process for dynamic correction of measurement errors in polymeric moisture sensors comprises determining the long term sorption behaviour by determining a chronological mean value (Mi), using the mean value and the instantaneous measured value (xi) to calculate a correction factor (Ki) which is dependent both on the value (xi) and on the difference (xi - Mi) according to the equation Ki = A.x1(xi - Mi), whereby the parameter (A) has a value which is dependent on the material and the construction of the sensor and the chronological mean value (Mi) is calculated using the expression. Mi = (N.Mi-1 + xi)/n+1, in which (N) is the quotient of the simulated decay period (TA) of the sorption process and the cycle time (TT) of the measurement cycle. USE/ADVANTAGE - The procedure allows correction of measurement errors encountered when using polymeric moisture sensors for measurement of the moisture content of gases, esp. air e.g. in ventilation and air conditioning units, making use of the change in dielectric constant of the polymer w.r.t. changes in its moisture content. The procedure makes use of the long term sorption behaviour of the sensor, which is detectable and reproducible, and the method does not use complicating factors such as heating the sensor element in dependence on the measurement value to limit the water uptake e.g. as described in DE2851686 and DE3011525.
