Patent DE-3943405-A1 (DE)
Title: Utilisation of low temperature heat for heating building - involves circulation air between inner panels and inner surface of walls
Inventor: WERNER FRIEDRICH
IPC: E04D13/18
Filed: 1989-12-30
Abstract: The method is for using a source of low temperature heat to reduce the heat loss from the interior of a building. Plaster board panels (12) are installed inside the building near to the inside wall surface so that a narrow gap (11) is formed between the panel and the wall (4). This gap is connected by a duct (13) to an external source (15) of low temperature heat, such as a solar panel (1) or warm waste water. Air heated from this source circulates by convection through the duct and gap and then flows out through the upper duct (9) into a space (6) between the wall (4) and an outer panel (7). The circulation of slightly heated air reduces the temperature difference across the wall (4) and so reduces the heat loss by conduction through the wall. USE/ADVANTAGE - More efficient heating of buildings.

Title: Measuring interference level of received signals e.g. TV - deriving measurement signal dependent on interference by subtracting function of useful signal from function of faulty signal
Inventor: AMANN ULRICH
IPC: G01R29/26
Filed: 1990-06-08
Abstract: Interference is measured at known times.  An interference signal is created by modulating the useful signal formed in a receiver.  A function of the useful signal is subtracted from a function of the interference signal to derive a measurement signal dependent on the interference level.  This measurement signal is used to control further stages. The functions can be spectral representation and/or mean value formulations of the signals.  The frequency of the received signal and/or the interference signal can be varied by a predetermined amount.  The useful signal can be formed from the input signal (Ue) of a receiver (10) via inputs (11,13,29).  A faulty signal is produced by modulating the useful signal.  A spectrum analyser (20) and/or a mean value stage (21) can be used to form the function signals. USE/ADVANTAGE - Moire pattern reception.  Objective evaulation of interference level on useful signal at useful to interference signal ratio level of cu. 70 dB.
