Patent EP-0221567-A3 (EP)
IPC: C08L81/02
Filed: 1986-11-07
Abstract: Corrosion of a melt-processing apparatus for 
processing a polyarylene thioether at a temperature 
higher than the melting point thereof is prevented by a 
method which comprises adding to l00 parts by weight of 
the polyarylene thioether 0.00l to l0 parts by weight of 
at least one member selected from the group consisting of 
(i) hydroxides of metals of the group IIa of the Periodic 
Table, (ii) oxides of metals of the group IIa of the 
Periodic Table and (iii) aromatic carboxylic acid salts 
of metals of the group IIa of the Periodic Table.  
     By this method, even if the melt-processing article 
obtained is exposed to moisture, the electrical 
properties of the article formed (for example, insulation 
characteristics) and the water resistance are not 
substantially deteriorated.

Title: Apparatus for transmitting streams of information bits and methods for estimating the most likely sequence sent
IPC: H04L27/38
Filed: 1986-04-25
Abstract: Embodiments of apparatus are described for transmitting a stream of information bits by sending corresponding signals over a channel in a plurality of signalling slots. 
<??>A family of multi-dimensional convolutionally coded modulation systems achieves enlarged minimum distance between possible sequences of signal points, reduced number of error events with the minimum distance, acceptable peak-to-average power ratio, reduced number of signal points in each constituent two-dimensional constellation, immunity to rapid carrier phase changes, and reduced complexity, resulting in a reduced error probability when maximum likelihood decoding is used. 
<??>These advantages are achieved by the construction and by the partitioning into subsets of the multi-dimensional constellation, by the design of convolutional codes using those multi-dimensional subsets, by using a bit converter and a block encoder to convert a multi-dimensional constellation mapping into multiple two-dimensional constellation mappings, and by a simplified decoding technique.

Patent EP-0223507-A3 (EP)
Title: Transmission line sensor apparatus
IPC: H02J9/00
Filed: 1986-11-05
Abstract: A self contained sensor module (1) mounted on a power transmission line (2). The module is capable of measuring various parameters such as line current, voltage, conductor temperature, and ambient temperature. The parameter values are processed by sensor electronics (25) which digitize and transmit the values to a ground receiver. The sensor module normally derives its power through electromagnetic induction resulting from current flowing through the transmission line. The module contains a power back-up system (27), including a battery, which allows sensor operation with minimum current and zero current in the transmission line. The battery is float charged while the sensor is mounted on the transmission line using excess energy derived through electromagnetic induction. When line current drops to a predetermined minimum value, float charging is disabled and the battery supplies power to the sensor module. When battery power is depleted to a predetermined level, data processing and transmission are disabled until the battery can be recharged.
Patent EP-0230202-A3 (EP)
IPC: G06F3/045
Filed: 1986-10-23
Abstract: A position responsive apparatus, system and method 
which employs a position responsive surface formed of two or­
thogonally disposed arrays of grid elements which in one em­
bodiment, the elements are coupled along one border with a 
resistor chain or the equivalent which is excited with an a.c. 
source at terminal locations. Capacitive coupling between the 
orthogonally disposed arrays at the cross-over locations of grid 
elements is significantly reduced by reducing the area of the 
grid elements at the cross-over positions. Further, intermediate 
grounding terminals serve to minimize disruptive potentials 
caused by the capacitive coupling. The control for the system 
employs a procedure wherein a correction look-up table is de­
veloped as part of the manufacture of the apparatus wherein 
readings are taken at the nodal points of communication be­
tween the grid array and the resistor chain and which then are 
treated to provide a regularly incremented sequence of address 
values developed from a signal domain computation. Physical 
domain coordinate values are correspondingly derived and are 
located in the table with each address value. The control for the 
embodiment accesses this memory for purpose of developing 
corrected coordinate outputs, thus eliminating the need for 
precise calibration of each resistor within the resistor chain. 
The invention further contemplates the employment of trans­
parent grid array elements. Significant improvements to per­
formance are achieved by exciting these elements from resis­
tor chains located and coupled therewith at oppositely dis­
posed ends of the grid elements. An improved switching ap­
proach is provided wherein excitation currents are employed at 
the switching stage which then are applied to voltage follower 
stages for coupling with the grid array terminal.

are suited for the production of multilayer films which 
have piezoelectric and pyroelectric properties, and 
which provide second harmonic generation.It is possible

Abstract: The process described provides a sloped contact 
etch. The process has the steps of: etching a 
substrate 12 then removing the polymer that is 
produced during the substrate 12 etch. These two 
steps are alternated until a desired depth is 
reached. Next, the resist 11 is etched followed by 
an etch of the substrate 12. This is then repeated 
until the required depth is reached. By varying the 
duration and repetition of the etches, the slope of 
the etch can be regulated.

A plant incorporting the method of making casting 
moulds includes the machining out of mould cavities 
the metal filling of the cavities, the positioning 
of blocks adjacent to each other on a conveyor system
