Abstract: A process for producing dimethyl carbonate is carried out by a first step of catalytically reacting carbon monoxide with methyl nitrite to produce dimethyl carbonate; a second step of absorbing dimethyl carbonate contained in a gas fraction withdrawn from the first step by dimethyl oxalate; a third step of regenerating methyl nitrite by contacting nitrogen monoxide contained in a gas fraction withdrawn from the second step with a molecular oxygen-containing gas and methyl alcohol; a fourth step of collecting dimethyl carbonate by distilling a liquid fraction withdrawn from the second step; and a fifth step of recovering methyl nitrite from a purge gas consisting of a portion of a regenerated gas fraction withdrawn from the third step by absorbing methyl nitrite in the purge gas by methyl alcohol to provide a methyl nitrite-containing liquid fraction and a nitrogen monoxide-containing gas fraction and bringing the gas fraction into contact with a molecular oxygen and methyl alcohol, to convert nitrogen monoxide in the gas fraction to methyl nitrite and to absorb this methyl nitrite by methyl alcohol, whereby methyl nitrite and nitrogen monoxide in the purge gas is recovered and reused with a high efficiency at a high level of safety.

Abstract: To implement a method of controlling individual or all the parameters influencing the combustion on a grate of a furnace, there is provided in the first place a radar measurement arrangement (22) which serves for detecting the three-dimensional distribution of the fuel mass on at least one preferred region of the grate of the furnace. Next to this, an infra-red camera (23) is provided, which provides information on the combustion behaviour of the fuel situated on the grate of the furnace. With the aid of the measured variables from these two arrangements, manipulated variables can be derived in a control unit for influencing the grate speed, the charging arrangement, the primary-air quantity, the primary-air composition, the secondary-air quantity, the secondary-air composition, the speed of the slag roller and the temperature of the air-preheating arrangement, in order thus to be able to adapt the grate capacity to the steam capacity requirement. At the same time, in addition to an improvement of the solid combustion on the grate, a positive influence on the waste gases, for example with regard to the formation of uncombusted gas components and nitrogen oxides, is also possible. <IMAGE>

Abstract: An op-amp comprising a single gain stage amplifier cascaded with a buffer and an output stage. The buffer comprises an amplifier which isolates the gain stage from the output stage to prevent loading of the gain stage and create a more linear op-amp. For frequency compensation, the op-amp utilizes MOSFETs connected in a reversed biased configuration as load compensation capacitors. This technique reduces the non-linear effects of MOSFET gate capacitors utilized in conventional Miller compensation schemes and allows for digital fabrication technology of low distortion, low power supply operational amplifier design.

Abstract: An apparatus for automatically controlling the gain of a spread spectrum signal receiver, which follows up at a high speed the instantaneous variation resulting from change in the distance, change in the median, and Rayleigh fading. The output of a variable gain amplifier (22) is orthogonally detected. The detected output is converted by an A/D converter. This digital output signal is fed to compressor (34) through a digital level corrector (33). The compressed spectrum output is instantaneously detected by an instantaneous envelope detector (37). The data symbol timing component of the signal detected is extracted by a symbol timing extractor (38) using the peak signal as trigger. From this symbol timing, the width of the window of time at which a desired wave arrives is calculated. Over this width of the window, the output of the instantaneous envelope detector (37) is integrated with respect to time by a level detector (43). By this output, the level of the digital level corrector (33) is shifted, thus making its output constant. Also, the values of the output of the level detector (43) are averaged by a level detector (44) over several symbols. By this output, the gain of the variable gain amplifier (22) is controlled, thus making its output constant.

Abstract: Un comparateur de tension produit une sortie de courant en fonction de la tension d'entrée différentielle. Trois fonctions de transfert sont explicitées. Dans le mode de transfert linéaire, la sortie varie de manière linéaire dans la région de transition et oscille entre zéro et une valeur de courant bien définie. Dans un mode de réponse tronqué, la sortie est nulle pour une tension d'entrée différentielle de zéro, reste à zéro pour une polarité de tension d'entrée, et s'accroît pour l'autre entrée de polarité, de manière linéaire, par rapport à une valeur de courant bien définie. Dans le mode de réponse plié, le courant de sortie est nul pour une entrée différentielle de zéro et s'accroît de manière linéaire dans la région de transition par rapport à une valeur de courant bien définie pour chaque polarité de l'entrée différentielle. Bien qu'une forme de structure CMOS soit préférée, la structure bipolaire est également illustrée.

A head-rest element (11) rests freely on the next mattress support element (12) which can be adjusted longitudinally on the sub-assembly framework (17). A greater number of configurations are possible, and handling of the bed is simplified by separating the frame from the sub-assemblies.

Abstract: The surface of the object reflects a focussed beam from a light source and the remission is detected by light detectors. The light source and detectors are arranged in a sensing head which can be moved linearly and pivoted. The position of the reflected light is determined on a CCD row used as a detector to determine the distance of the detected point on the object surface. The object is rotated to enable peripheral, annular, horizontal scanning in the z direction. The resulting data are stored and used for three-dimensional reconstruction of the object with a data processing unit. The annular scan is repeated with a predefined z-scan step using different angular positions of the sensing head, e.g. for detecting undercuts, covered points or x-parallel planes or surfaces.

Abstract: The present invention relates to an arrangement for a multiple light path, which may be used for a wireless optical audio and/or video communication system. 
     Known systems use a direct wireless infrared connection. It has been found that such a connection is not reliable enough. 
It is the object of this invention to realise a reliable infrared connection between different devices. 
This is realised by a two path connection. A first path is realised by a wireless connection and a second path is realised by a transmission at least partially through an optical fibre. 
Furthermore this invention presents a special lens and a special photo light emitting diode for the realisation of the two path infrared connection. 
     The invention can used e.g. for the connection between a television set and a video cassette recorder.
