Patent EP-0355849-A3 (EP)
IPC: G01N35/04
Filed: 1989-08-25
Abstract: An analyzer has a reaction disk (1) for 
holding a plurality of reaction containers (2) and a 
fluorophotometer (19) for measuring fluorescence 
stemming from solutions in the containers. Most of the 
containers contain solid phases (50) attached with 
antibodies (51) but at least one container does not 
contain any solid phase. In normal operation of the 
analyzer, a test sample (11) containing antigens (53) 
and a latently fluorescent reagent such as antibodies 
labeled by enzyme are added to a container (2) 
containing a solid phase (50). In this container, a 
fluorescent substance is created through an enzyme 
reaction. Exciting light (22) is irradiated on the 
container and fluorescence emitted from the fluorescent 
substance is measured. In mid course of measurement 
operation of test samples, fluorescence stemming from a 
reference sample (12) such as quinine sulfate is 
measured to produce measured values for the reference 
sample by which measured values for the test samples are 
corrected. Prior to measurement of general test samples 
(11) by the analyzer, fluorescence stemming from a 
reference sample (12) in a container removed of any 
solid phase is measured to enable the analyzer itself to 
decide whether the analyzer operates normally. In this 
 
 
case, a value measured for the reference sample is 
compared with a setting value. When the results of 
comparison indicate that the normal operation is 
difficult to continue, the sampling operation by the 
pipetter is discontinued.
Patent EP-0359064-A3 (EP)
Title: Computing system
IPC: G06F13/00
Filed: 1989-09-01
Abstract: An inexpensive to manufacture switch is presented which 
allows a computer terminal port to be coupled to one of a 
plurality of remote computer ports. The switch includes 
receivers (218) which receive signals from each of the 
remote computer ports and transforms the voltage level of 
the signals allowing the signals to be processed by 
transistor-to-transistor logic (TTL) circuits. A 
multiplexor (210), based on voltage levels on a series 
of address lines, selects one of the remote computer 
ports from which to receive signals. The selected signals 
are forwarded to a driver (219) which restores the select­
ed signals to the original voltage level and couples the 
selected signals to the computer terminal port. 
Similarly, a receiver (217) receives signals from the 
computer terminal port and transforms the voltage level 
of these signals allowing the signals to be processed by 
TTL circuits. A demultiplexor (214), based on voltage 
levels on the series of address lines, places the signals 
on a line for the selected remote computer port. The 
signals then are forwarded to a driver (220) which 
restores the signals to the original voltage level and 
couples the signals to the selected remote computer port.

Patent EP-0327191-A3 (EP)
Title: Resistive fault location means and device for use on electrical cables
IPC: G01R31/08
Filed: 1989-01-05
Abstract: A resistive fault in an electrical cable is 
located by applying a DC voltage to one end of the 
faulted cable conductor. The steady state DC voltage and 
current are measured at the end of the conductor where 
the voltage is applied. Simultaneously, the DC voltage 
is measured at the other end of the cable. The voltage 
is then reversed in polarity and the measurements 
repeated. Several repetitions of this procedure at each 
end of the conductor yields sufficient information to 
compute the location of the fault with reasonable 
accuracy. The procedure is carried out using two 
computer-based units, one at each end of the cable, with 
the two units communicating over the conductor under 
test.

Title: Information handling centre telecommunication servers
IPC: H04J3/12
Filed: 1989-07-14
Abstract: A dual digital signal processor (DSP) provides real time links between 
multiple time division channels of a digital carrier system (e.g. T-1) 
and a host data processor. Operating only on digital signals, 
internally and at its interfaces to the carrier and host systems, the 
DSP exchanges data and control signalling information with the carrier 
system and data and control information with the host processor, 
converting the data in passage to different digital forms. At the 
interface to the carrier system, signals are received and transmitted 
in a form adapted to diverse terminal equipment of users remotely 
linked to the carrier system via the switched public network. At the 
host interface, signals are transferred and received in a form suited 
to the data process requirements of the host system (e.g. data bytes 
directly representing alphanumeric characters). Thus, the DSP acts as 
the equivalent of multiple different types of modems in performing 
required conversions. The DSP may also perform processing services in 
order to reduce the processing burden on the host system (e.g. parity 
checking of data, detection of specific character functions in data or 
specific tones in audio signals, selective routing of voice to host 
storage for voice mail applications, etc.)

Title: Seismic data processing
IPC: G01V1/28
Filed: 1989-08-11
Abstract: In a method for identifying anomalous noise amplitudes in 
seismic records, a measured amplitude factor is derived over 
predetermined periods of time or time 
windows for a predetermined number of traces comprising 
the records. A noise-free amplitude factor 
for the same periods of time and number of traces is also 
computed using a Gauss-Siedel method of matrix inversion. 
A ratio of the measured and noise-free amplitude factors 
is made to determine a correction factor which is 
compared to a used defined threshold value for 
determining a presence of anomalous noise amplitudes in 
the seismic records. Based on the comparison of the 
correction factor to the threshold value, the user 
determines whether to suppress or correct traces 
experiencing the anomalous noise amplitudes.

Title: Apparatus for fine spatial resolution measurements of earth formations
IPC: G01V5/12
Filed: 1989-12-07
Abstract: A high resolution gamma-gamma apparatus is provided with a 
chemical source (120) and a photon detector (127) in such close proximity 
such that the detector provides a positive response to an 
increase in formation density. Typically, such a response is 
obtained when the detector opening is within one source photon 
mean free path of the source opening. For a Cs 137 source, the 
furthest spacing would be about two inches, although spacings of 
less than one inch are preferable. In order to decrease 
background noise, shielding (135) is placed between the source and 
detector. A first embodiment of the tool has an uncollimated 
source, and a substantially uncollimated detector with the 
source and detector being coaxial and with the detector behind 
the source and separated by shielding. A second embodiment has 
a collimated source with an uncollimated detector, while a third 
embodiment has an uncollimated source with a collimated 
detector. The provided apparatus are useful for high resolution 
density and Pe measurements. Additional axially spaced negative 
response detectors may be included to provide additional 
information which are useful in correcting for environmental 
effects. Also, circumferentially spaced detectors along with 
additional sources are useful in conducting dip analysis.

Abstract: The invention includes an isostatic press supply 
of heat to a workpiece by microwave energy and a method 
for isostatically pressing a powdered ceramic or 
powdered metal material that is heated by microwave 
energy. The isostatic press includes a pressure 
vessel. A fluid medium is available for supply to the 
pressure vessel under pressure. The invention further

the pressure vessel. The method includes preparing a 
workpiece comprising a microwave coupler material. 
Desirably, the workpiece is a composition comprising a 
powdered coupler or semiconductor and a powdered 
insulator. The workpiece is immersed in an additional 
powdered insulator which is transparent to the 
microwave energy. The workpiece and immersing powdered 
insulator are contained in a closed, compressible 
container. The contained, immersed workpiece is then 
placed into a pressure vessel. Microwave energy is 
transmitted into the pressure vessel at a sufficient 
 
 
frequency to couple with the coupler. A fluid medium 
is supplied into the vessel under pressure either 
concurrently and/or before and/or after the 
transmission of microwave energy. The microwave energy 
couples with the coupler which causes the insulator of 
the workpiece to heat. The immersing insulator that 
surrounds the workpiece remains cool.
