Title: Demagnetization of thin film magnetic recording transducers utilizing a decreasing ac current
IPC: G11B19/04
Filed: 1989-06-13
Abstract: Noise in the readback signal of a magnetic recording 
device resulting from spurious pulses in the readback signal 
produced by transitions of the magnetic remanent state of 
the yoke in the read/write transducer is eliminated by 
controlling the occurrence of the spurious pulses. 
Immediately following the completion of the write process, a 
decreasing amplitude alternating current (58) is applied to 
the read/write coil (49) of the transducer to drive the yoke 
remanent state to a stable or zero remanent state prior to 
the commencement of the read process.
Patent EP-0364986-A3 (EP)
Title: Apparatus for reproducing video and audio signals
IPC: G11B5/09
Filed: 1989-10-18
Abstract: A pair of bimorph leaves (BM1, BM2) are mounted on a rotary 
drum (DR) and each bimorph leaf (BM1, BM2) includes four re­
producing heads (P(A1),...P(D2)). A pair of recording head 
means, each of said means including two recording heads 
(R(A),...R(D)), are provided so that four record heads are 
used to form twelve tracks (A1,...) during three times of 
rotation of the rotary drum (DR) in one field period in a 
case of PAL television signal recording mode. The eight re­
producing heads (P(A1),...P(D2)) are used to scan said twelve 
tracks so that the twelve tracks can be scanned within two 
times of rotation of the rotary drum (DR). In a case of re­
cording and reproducing an NTSC television signal, the rotary 
drum (DR) rotates two times and a half during one field period 
of the NTSC signal so that the four record heads form ten 
tracks per field period. Eight reproducing heads are also 
used to scan the ten tracks in a same manner. Such arrangement 
of the record and reproducing heads makes a moving distance 
of the pair of bimorph leaves (BM1, BM2) reduced in a repro­
ducing mode, the tape speed of which is different from that 
of the recording mode.
Patent EP-0371357-A3 (EP)
Title: Method of determination of signal reception time by means of correlation technique
IPC: H04L7/00
Filed: 1989-11-17
Abstract: A method of determining the reception time of a signal containing a predetermined code, e.g. a Barker code. The code may be present at the start of a telegram to be received by a mobile radio from a base station. The signal is correlated with a corresponding code stored in memory. The correlation is carried out at different offsets in time. This gives a correlation curve (figure 2). The apex represents peak correlation. The timing of optimum correlation is determined by extrapolating the sides to the apex. The invention also provides a zero crossing detector for timing zero crossing events whereby sufficiently accurate timing of receipt of the code is possible to enable meaningful correlation.

Patent EP-0339779-A3 (EP)
Title: Automated capillary electrophoresis apparatus
IPC: G01N27/447
Filed: 1989-03-14
Abstract: An automated apparatus and system for 
effecting capillary electrophoresis is disclosed. The 
system includes two conveyors (R₁,R₂) for conveying septum sealed 
vials into registry underneath a cartridge (C) containing a 
capillary for capillary electrophoresis. The capillary 
interior of the cartridge is wound in a serpentine path. 
The capillary depends at its two distal ends downwardly 
from the cartridge at two spaced apart locations from 
the bottom surface of the cartridge. The vials, each 
held in a vial holder, are conveyed until one vial on 
one conveyor underlies one depending distal capillary 
end and the other vial on the other conveyor underlies 
the other depending distal capillary end. Once registry 
of the vials to the distal capillary ends has occurred, 
the vials are moved upwardly -- typically by piston 
assisted movement of vial holders with respect to the 
conveyors. Such upward piston assisted movement con­
tinues until the vials are pierced at a sealing septum 
by hypodermics. After piercing of the hypodermics, the 
piston assisted upward movement continues to thread the 
hypodermic with either a capillary or an electrode for 
access to the content to the interior of the vial. The 
apparatus and process actuates a sequence of vials to 
produce automated capillary electrophoresis. The se­
quence includes charging the capillary at a first vial 
with electrolyte and thereafter injecting from a second 
and different vial a predetermined amount of sample 
into the electrolyte filled capillary. After sample 
injection the sequence includes causing paired third 
and fourth vials of electrolyte to be communicated to 
the depending ends of the capillary, communicating 
 
 
electrodes to each of the third and fourth vials to 
produce the required electric force for capillary 
electrophoresis and permitting the capillaries to be 
exposed at its distal ends to the electric forces for a 
sufficient period of time to cause sample classification 
due to the electrophoresis. Provision is made in the 
cartridge immediately adjacent one of the ends thereof 
for detection of the electrophoretically classified 
components. The detection schemes including fluores­
cence, light absorption or reflection, light deflection 
responsive to electrical changing optical index. Upon 
completion of the electrophoresis, the capillary is 
recharged with electrolyte and the process endlessly 
repeated using differing sequences of vial. The con­
tinued electrophoresis either uses the same capillary 
in the same cartridge or a differing capillary mounted 
to a different cartridge.

Patent EP-0376695-A3 (EP)
Title: Operator-defined dialog boxes and processing logic for computer systems
IPC: G06F17/21
Filed: 1989-12-27
Abstract: A computer system is provided for obtaining and recording 
information by presenting selected data, warnings and inquiries on a 
computer display monitor, prompting selected responses to the warnings 
and inquiries as desired, and integrating newly obtained information 
with other data to create a completed document. The system creates 
"dialog boxes" which are defined by an expert operator. To create a 
dialog box, the operator defines a location in the document in which a 
question is to be asked or information provided to the user. The 
operator also defines the question or information, and can also 
provide several responses to the question. The operator can specify 
the number of answers which can be accepted in response to an inquiry, 
and can specify that certain information, such as a date or the like, 
be provided.  
     The dialog boxes can be arranged in an information 
tree structure having multiple branches. The branches of the tree 
which are actually used are determined by the responses received to 
inquiries as information is obtained. Macros can also be integrated 
into the tree structure, if desired. The operator's selection of 
sequential responses to the questions thereby determines how the 
document develops. As questions are answered, the information obtained 
is inserted into the text of the completed document, and the inquiries 
are erased. In this manner, someone having expert knowledge in a field 
other than computer programming can develop a system which persons 
with less knowledge in the field can use to obtain information and 
assemble it in an integrated and easy to understand narrative text 
format.
