Abstract: A description is given of a method for regenerating an adsorbent which is freed by a hot gas of a medium adsorbed in the adsorbent, in particular humidity, and is subsequently cooled by means of a gas stream. To avoid undesired heating up of the exhaust gas stream and/or of the drying air, it is provided that, for cooling, a gas stream emerging from the hot adsorbent (26) is passed through a heat accumulator (50) for taking up the heat from the hot adsorbent (26) and, after the heat accumulator (50), is passed back through the adsorbent (26). Furthermore, a device suitable for carrying out the method is specified. <IMAGE>

Abstract: A modem receives data sent from a remote device over a communication channel by using a single carrier modulated signal. The modem includes a receiver which receives the modulated signal and a line probing signal sent by the remote device over the channel. The receiver is capable of receiving the modulated signal over any one of a plurality of frequency bands. A line probing processor measures characteristics of the channel based upon the received line probing signal. A selector selects one of the plurality of frequency bands, this selection being based upon the measured characteristics of the channel. The selected frequency band is to be used for receiving the modulated signal from the remote device.

Abstract: An FM receiver includes an RF section, a first mixer stage for converting a desired RF reception signal into a first IF signal having a carrier frequency located on average at a first intermediate frequency, a first IF section for selecting the first IF signal, and a second mixer stage for converting the first IF signal into a second IF signal having a carrier frequency located on average at a second intermediate frequency. The second intermediate frequency is below the first intermediate frequency. A second IF section selects the second IF signal and is coupled to an FM demodulator for demodulating the baseband modulation signal of the desired RF reception signal, followed by a low-pass filter for selecting the baseband modulation signal. In order to enhance the signal processing of the FM receiver and to realize a receiver in a largely integrated form, to provide a substantially fully integrable IF stage which is easily exchangeable with the IF section of substantially all existing FM receivers of the superheterodyne type, and to realize a selectivity considerably greater than that of known IF filters, a third mixer stage is coupled between the second IF section and the FM demodulator for converting the second IF signal to a third IF signal having a carrier frequency located on average at a third intermediate frequency which is above the second intermediate frequency.

Abstract: New intermediate compounds that can be used effectively for the synthesis of a broad range of 1 alpha -hydroxy-19-nor-vitamin D compounds. These novel intermediates are characterized by a group selected from hydroxy methyl (-CH2OH), carboxaldehyde (-CHO), and carboxy ester (-COOAlkyl) at the carbon 22 position of the side chain of a 19-nor-vitamin D nucleus. Intermediates of this type are useful for the introduction of side chain units and thus represent important synthons for the preparation of many different 19-nor-vitamin D compounds.

Abstract: Polymers comprising poly(4-hydroxystyrene) and/or substituted poly(4-hydroxystyrene) are produced by polymerizing 4-acetoxystyrene and/or substituted 4-acetoxystyrene monomers, with or without other comonomers, and subsequently performing transesterification. Preferably, the polymers are produced using at least one alcohol as a reaction medium, a chain transfer agent and a transesterification reactant. It is appropriate: to use an initiator which does not comprise a substantially absorbant structure over the 240 to 260 nm range or to use an initiator concentration of less than about 3 mole % of the monomer(s); to obtain a polymerization conversion of the initial polymerization monomers of at least about 90% by weight, or to remove residual monomer(s) from the reaction medium prior to transesterification; to obtain a transesterification conversion of the polymerized monomers of at least 85% by weight; and to avoid the use of transesterification catalysts which can cause the formation of chemical structures which can absorb over the 240 to 260 nm radiation wavelength range. The target polymers have low optical density (absorbance) over a wavelength range from 240 to 260 nm, as well as low optical density over the near UV and visible spectrum (310 to 800 nm); and are useful as photoresist components for use in combination with deep UV, X-ray, and E-Beam imaging systems.

Abstract: Spent kieselguhr used as a filter medium, preferably in breweries, is regenerated by adding 2 to 8% sodium hydroxide solution at a reaction temperature of about 60 to 90 DEG C and subjecting it to gentle stirring for a reaction time from 30 to 120 minutes. The concentration of the sodium hydroxide solution is then 4 to 5% and the reaction temperature 80 to 90 DEG C. The spent kieselguhr is discharged into a heatable vessel. After the end of the reaction time, the sodium hydroxide solution is removed and the kieselguhr is washed clear by means of a vacuum filter or pressurised belt filter in a plurality of extraction stages. For complete removal of the alkali, sulphuric acid or hydrochloric acid in a concentration of up to 0.1% is added to the washing water in the last extraction stage.

Abstract: In an internal combustion engine with oxygen sensors provided respectively upstream and downstream of an exhaust purification catalytic converter, the air-fuel ratio is feedback controlled based on an output of the second oxygen sensor only. When in this control situation, an output period of the first oxygen sensor becomes longer than that of the second oxygen sensor, response deterioration of the first oxygen sensor is judged to have occurred. Once the occurrence of response deterioration is determined, a proportional operating amount used in a proportional control of an air-fuel ratio feedback correction coefficient LMD for air-fuel ratio feedback control using the first oxygen sensor, is corrected in proportion to the response deterioration to thereby correct a deviation of the air-fuel ratio control point. As a result, response deterioration of the first oxygen sensor can be diagnosed, and deviation of the air-fuel ratio control point due to the response deterioration can be avoided, so that control accuracy to the target air-fuel ratio can be ensured.

Abstract: A testing integrated circuit using an A/D converter provided in an integrated circuit on a semiconductor chip. A selector is provided for selecting either an external signal supplied from an external portion of the chip or an internal signal generated by an internal circuit of the chip, and for outputting the selected signal. The A/D converter, which receives an output from the selector, is normally used for A/D-converting an external signal. During reliability test, the A/D converter receives a signal to measure a voltage from the internal portion of the chip, and A/D-converts the received signal. An output pad which transmits the output of the A/D converter to the external portion is also used as a general output pad. The general output pad is employed to A/D-convert the external signal.
