Patent EP-0348940-A3 (EP)
Title: Uplink cross-polarization interference canceller using correlation calculator and stepwise tracking controller
IPC: H04B7/00
Filed: 1989-06-28
Abstract: In a satellite communications system, 
a rotatable 90 o  phase shifter (4) and 
a rotatable 180 o  phase shifter (3) introduce 
variable phase shifts to a single pilot 
signal, which is transmitted to the 
satellite. Downlink cross-polarization 
interference cancelling control signals are derived from a beacon signal 
received from the satellite. A pulse 
sequence is generated to modulate the 
amplitude of a carrier to produce an ASK signal as the pilot signal. A 
correlation calculator (19) provides coarse 
mode interference cancellation by 
estimating uplink cross-polarization interference components from the 
downlink cross-polarization cancelling control signals and adjusting the 
angle settings of the 90 o  and 180 o  phase shifters with the estimated 
components. The pilot signal is transmitted back to the earth and 
synchronously detected with the pulse 
sequence to derive a DC signal which 
represents an uplink cross-polarization 
interference. A stepwise tracking 
controller (16) provides fine mode 
interference cancellation by stepwisely 
varying the 90 o  and 180 o  phase shifters by predetermined amounts an 
detecting previous and recent values of the synchronously detected DC 
signal resulting from the stepwise variations, and repeating the stepwise 
variations until a difference between the previous and recent values is 
substantialy reduced to a minimum.

Title: Discrete tungsten complexes as oxygen and water resistant dcpd polymerization catalysts
IPC: C08F4/78
Filed: 1990-02-22
Abstract: This invention is a process for preparing a polymer 
which comprises contacting pure dicyclopentadiene with a pure 
tungsten catalyst complex, such as WCl₃(2,6-diisopropyl­
phenoxy)₃, when tributyl tin hydride or triphenyl tin 
hydride is used as the activator for the polymerization. 
This process affords a method of polymerization of 
dicyclopentadiene in which the mixture gels slowly without 
the use of a rate moderator at 80°C. (in from about 15 
seconds to as much as two minutes or more) and furthermore 
cures quite slowly (in about 3-6 minutes). This delay makes 
these compositions particularly applicable to reaction 
injection molding processes. Moreover, both the tungsten 
complexes and the tin activator compounds employed in this 
invention are relatively insensitive to oxygen and water.

could not be made compatible in instantaneousness. But in 
the present invention, the individual size is continuously 
stored into the storage media physically, and the input, 
output of the data and the storage reproduction with the 
storage media are effected in the non-synchronization, with 
the size of the input/output buffer, the unit of the in­
put/output of the audio and the picture information, and the 
unit of the edition being the same in size so as to realize 
the instantaneousness and the continuous input/output 
operations of the edition.

Title: Optical analytical instrument and method
IPC: G01N21/31
Filed: 1991-10-11
Abstract: Optical analytical instruments to determine a physical parameter of a fluid, and methods of operation of such instruments, are shown. These employ a source of suitable optical radiation, a detector means, means defining a zone for the fluid, means defining an optical path from the radiation source through the fluid zone to the detector means, and reading and control circuitry. At least two readings of optical energy that has been influenced by the fluid are taken without there having occurred substantial change to the fluid. During one of the readings a filter of known absorbance is included in the optical path so that the respective reading represents a calibration reading. A calibration-value-determining means is constructed first to compare, effectively, the two readings to remove the effect of the fluid from the value of the calibration reading, second, to compare, effectively the residual value of the calibration reading to a known value based on the known absorbance of the filter, and, third, on the basis of the second comparison, to make a calibration adjustment based on values derived while the fluid sample remained unchanged in the fluid zone. Novel software implementations of the determinations are shown. Specific examples of instruments and methods implementing these features shown are a dual lamp, no-moving part in-line spectrophotometer, a no-moving part reflection colorimeter capable of on-line or off-line operation, a scatter or fluorescence detecting implementation and a turbidimeter.
