Patent EP-0003388-A1 (EP)
Inventor: PARKER NORMAN WILLIAM
IPC: H04H1/00
Filed: 1979-01-03
Abstract: The cosine correction factor of a receiver for compatible AM stereo reception is controlled by the amount of high frequency energy present in the demodulated signal. Large amounts of such energy indicate a low signal-to-noise ratio and cosine correction under such conditions is then not desirable. During periods of excessive high frequency energy, a filter circuit output causes a switching circuit to remove the derived cosine correction factor and cause division of the demodulated signal by a factor of one instead. The output of a cosine phase detector (24) is coupled to a divider (25) through the switching circuit (27). The output of the detector (24) is also coupled to a high pass filter (29), an output of which is coupled to a first control input of the switching circuit (27). A second control input (30) provides a reference signal. When the S/N ratio of the received signal is low and thus the output of a limiter, which contains only the phase information of the received signai, contains large amounts of high frequency energy, the high pass filter (29) provides to the switching circui; (27), a control voitage sufficient to disconnect the output of the detector (24) from the divider (25) and to substitute therefor the reference voltage which is such as to cause the divider (25) to effectively divide the dEmodviated signal (L-R) cos ø signal by a factor of one.

Abstract: A process (and apparatus therefor) for carrying out thermally initiated chemical reactions or physical changes by heating a particular substrate in a fluidised bed having hotter zone(s) and cooler zone(s) between which the fluidised particles circulate, the dwell time in the hotter zone(s) being sufficiently short so as to prevent the particles undergoing an undesirable thermal transformation, and/or the dwell time in the cooler zone(s) being sufficiently long to allow chemical reaction and/or physical changes to take place which prevent undesirable thermal transformations occurring in the hotter zone(s). The fluidised bed process is applicable, for example, to the polymerisation of a low molecular weight poly(ethylene terephthalate) and to a process for the preparation of poly (ethylene terephthalate) from a terephthalic acid and ethylene oxide.

Abstract: Concentrated alcohol and distillery slop are produced from fermented beer with a reduced amount of energy by employing a vapor recompression distillery slop evaporator in which evaporator vapors are used to strip alcohol from the fermented liquor before they are returned as the heat source for evaporation. Vents (11) in the evaporator permit passage of uncondensed vapors used to drive the evaporator (7) to a rectifier (12), in which they constitute the principal heat and alcohol source. Condensed vapors from the evaporator and the bottom stream from the rectifier are stripped of their remaining alcohol content in a condensate stripper (13), which is also driven by the recompressed vapors from the evaporator. This prevents dilution of the slops and the additional energy cost that would be necessary if the water content of these streams had to be removed in the slop evaporator.

Abstract: To improve the uniformness of patterns for LSI circuits or masks generated in an electron beam lithographic system, a backscatter indicator signal (BS indicator) is obtained and used to vary a control signal (SRF) for the beam stepping rate proportional to the variations in the amount of backscattered electrons. This avoids non-uniformity such as line width variations which otherwise occur when the pattern to be generated covers border lines between two different substrate or base layer materials. Special range setting circuitry (47) is provided for adjusting, during an initial prescan of a sample of two materials having an extreme difference in their backscatter characteristic, the offset and the gain for the backscatter detector (41). During subsequent exposure of a wafer, the backscatter indicator signal and thus the stepping rate control signal variations remain within preselected limits.
