Patent EP-0287929-A2 (EP)
Inventor: SANDRIDGE ROBERT L
IPC: G01N21/31
Filed: 1988-04-12
Abstract: A particular area or areas are monitored for the presence of gaseous materials, particularly pollutants by collecting background radiation (both visible and infrared radiation) present in the selected area, analyzing the radiation collected with a spectrometer and making the results of this analysis available in a form understandable to the person or device monitoring the area for the presence of specified gaseous materials. The results of the spectrometric analysis may, for example, be displayed on a video unit or they may be printed. In a preferred embodiment, the results of the spectrometric analysis are displayed on a video unit simultaneously or sequentially with the image of the area from which the background radiation had been collected. Apparatus useful in the practice of this invention generally includes large energy collecting mirrors, an interferometer of the Michaelson-Morely type, a sensitive infrared detector, electronic data processing, and a device which records and/or displays the results of the determination(s). In a preferred apparatus, a "hot" mirror, a video camera, a computer and a video display unit are also employed.

Abstract: In this device, two parallel incremental tracks (5, 6), which are offset with respect to one another by T/4, of the same incremental period T are arranged on a scale (1) on both sides of a reference marker (7). Along the scale (1), a scanning unit with a scanning plate (2) is conducted which also has an incremental division with the incremental period T, both incremental tracks (5, 6) and the reference marker (7) being scanned with this increment by photodetectors (12, 13, 14) located in one line below one another. Due to the symmetric arrangement of the incremental tracks (5, 6) relative to the reference marker (7), the required relation between the reference pulse (UR, URF) and the counting signals which are obtained from the analog scanning signals of the incremental tracks (5, 6) is retained even when the scanning plate (2) is tilted relative to the scale (Figure 1). <IMAGE>

Abstract: In a radio communication network system for use in carrying out communication with a plurality of radio telephone sets in a service zone by the use of a control channel and a plurality of speech channels, a connecting equipment unit (CE) is selectively operable in cooperation with a radio control unit (RCU) in a speech mode of forming a speech path through a selected one of the speech channels and an additional mode of selectively monitoring the control and the speech channels. The additional mode may be divided into first and second control modes for allowing and rejecting reception of a call with the control channel monitored, respectively. Alternatively, either a rest mode or a combination of rest and initial program loading modes may be added to the additional mode. A plurality of the connecting equipment units may be located in a single service zone and selectively put into the speech and the additional modes with only one of the connecting equipment units kept in the first control mode.

Abstract: A compressed gas mixture, particularly air, is separated in adsorbent beds 6 and 8 in turn. The adsorbent adsorbs nitrogen in preference to oxygen and argon. Accordingly, product gas rich in oxygen is delivered to pipeline 44. While one bed adsorbs nitrogen from compressed air, the other is regenerated by being placed in communication with the atmosphere through vent pipe 30. At the end of each adsorption step the respective bed 6 or 8 is placed in communication with a bed 12 of adsorbent that adsorbs oxygen more rapidly than nitrogen and argon, and the pressure between the two beds is equalised. The pressure between the beds 6 and 8 is then equalised. Unadsorbed gas comprising argon and nitrogen is vented from bed 12 to the atmosphere and then the bed 12 is placed in communication with either bed 6 or bed 8 to cause oxygen to be desorbed from bed 12 and to enter the bed 6 or 8. The venting of argon to the atmosphere reduces the argon content of the product.

Abstract: A method of forming a superconductive joint between superconductors made of filaments of superconducting material embedded in a matrix material utilizes two baths of molten metals. One of the baths of molten metal is used for etching the matrix material away from the superconducting filaments and is vibrated at an ultrasonic frequency. The other bath is also vibrated at an ultra­sonic frequency and is used to mold the etched superconductors into a superconducting joint. Superconducting joints may thereby be made under ordinary atmospheric conditions between superconducting wires having similar and/or different matrix materials.

Abstract: For the pigmenting of high-molecular weight organic materials, there is a high demand in industry for high-hiding-power organic red pigments, in particular yellowish red pigments, which are increasingly being employed as a substitute for ecologically unacceptable inorganic red pigments. However, this market opportunity cannot be satisfactorily exploited using the tetrachloroperylenetetracarboxylic acid diimide pigments known for the abovementioned purpose. 
<??>It has now been observed according to the invention that a chlorine content of </= 25% in chlorinated perylimides of this type gives the pigments produced on this basis extraordinary dyeing properties, so that these pigments have better hiding power and body colour than the tetrachloroperylimide compounds described. Accordingly, the invention relates to high-hiding-power red pigments of the halogenated perylenetetracarboxylic acid diimide type having up to 4 carbon atoms with a chlorine content of 15-25%, which are in the form of mixed crystal pigments in the  beta -modification having an optimum mean particle size of </= 0.15  mu m. Perylimide compounds having a higher chlorine content favour the simultaneous formation of the  alpha -phase.

Abstract: An adaptive active acoustic attenuation system is provided with extended frequency range to attenuate undesired noise which was previously filtered out to avoid instability of the adaptive model. The input signal from the input microphone (42) to the model (38) and the error signal from the error microphone (46) to the model are differently bandpass filtered to provide a narrower frequency range error signal. In one embodiment, the model operates in its stable region to provide accurate well behaved correction signals to the cancelling loudspeaker (50), while still receiving a low frequency input noise signal from the input microphone including frequencies below such range. Minimum attenuation frequency has been reduced by at least an octave.
