Abstract: A filter unit for purifying the air necessary for equalising the press. in encapsulated electronic devices comprises a particle filter and an absorption filter fixed into a suitable opening in the filter housing such that the equalisation of press.  can only take place via this route. Pref. the filter housing is made of thin-walled corrosion resistant metal. The filter is pref. constructed such that any condensate formed can drain away through the filter. Pref. the filter housing is conductive and is cylindrical or conical with a dia. of 0.5-2 cm and a length of 1-5 cm. The adsorber layer is e.g. of one or more of 0.1 - 2 mm particulate active carbon, 0.1-1 mm spherical particles of pitch or ion exchange resin, a molecular sieve and metal cpds. with catalytic properties. The adsorber layer is pref.  held under light compression in the filter housing by means of elastic foam plugs at each end of the tube to avoid settling and the formation of channels. The foam plugs may be combined with the paticle filter layers. USE/ADVATNAGE - The filter units are incorporated into externally cooled encapsulated electronic devices, esp. aircraft 'Black Box' type flight recorders, which are subjected to changes in temp. and press. whilst in service and therefore breathe. By filtering out any particulate matter and vapours from the air entering the appts. the equipment is given an improved working environment which improves reliability of operation and prolongs the useful life of the device.

Patent DE-3927833-A1 (DE)
Inventor: LOCHER JOHANNES ING GRAD
IPC: G01R27/26
Filed: 1989-08-23
Abstract: A circuit (MS) for measuring the value of an impedance in an impedance network connected to the measurement circuit has first oscillator means (OSZ1), second oscillator means (OSZ2), a phase-controlled rectifier (PG), comparator means (AG) between a desired value and a real value and an integrator (I). The first oscillator means apply a first alternative voltage of constant amplitude and frequency to a first output connection (A1). The second oscillator means apply a second alternative voltage of identical frequency, but variable amplitude and opposite phase, to a second output connection (A2). The amplitude of the second alternative voltage depends on the phase of the signal which is transmitted to the phase-controlled rectifier via an input connection (E). If the input signal is in phase with the second output signal, the amplitude of the second output signal is reduced. If the phase of the input signal is opposite, however, to the phase of the second output signal, the amplitude of the second output signal is increased. The amplitude is changed by means of the integrator, which integrates the rectified signal that has been rectified and compared with a desired value, and supplies the integration value as an amplitude setting value. If an impedance network is connected to this measurement circuit in an appropriate manner, the amplitude of the second output signal is set to a fixed value. From the relationship between the amplitudes of both output signals and known properties of the impedance network, the impedance value of a predetermined impedance, which is at first unknown, can be determined very precisely. The circuit is therefore particularly useful with position sensors in motor vehicles.
