Patent EP-0307790-A3 (EP)
Title: Electrochemical gas sensor
IPC: G01N27/49
Filed: 1988-09-08
Abstract: Electrochemical sensor cells having reduced zero current 
temperature sensitivity comprise a working electrode and a counter 
electrode in close proximity and in contact with an electrolyte. Both 
electrodes are exposed to the atmosphere to be tested and at least a 
portion of the counter electrode is masked from the electrochemically 
active gas in the atmosphere.
Patent EP-0311979-A3 (EP)
IPC: G02F1/315
Filed: 1988-10-11
Abstract: An electro-optic switching device using ferro­
electric liquid crystals (40) to either transmit or 
reflect the incident light depending upon the molecular 
orientation of the ferroelectric liquid crystal mole­
cules (40). An applied voltage across conductive 
coatings (44,45) causes the ferroelectric molecules (40) 
to switch from a first state in which the incident 
light is substantially transmitted to a state in which 
the incident light is substantially reflected. This 
is accomplished by effectively changing the refractive 
index of the ferroelectric liquid crystal (40) in the 
different states. The ferroelectric liquid crystal 
(40) is disposed between two dielectric mediums (42 and 
43) such as glass so as to define a boundary which 
either causes incident light to change direction or 
its complex amplitude to change, and the smectic 
layers (41) of the ferroelectric liquid crystals (40) 
are oriented such that the incident light is selec­
tively switched to one or more outputs (13 and/or 14). 
The molecules are also oriented so as to rotate in 
a plane perpendicular to the applied field, thereby 
reducing the switching time between the first and 
second molecular orientations. In addition, the 
switching effect may be made operative solely by the 
presence or absence of light by generating the applied 
electric field from the incident light.

Title: Preparation of poly (arylene sulfide)
IPC: C08G75/0213
Filed: 1988-08-18
Abstract: In a process in which a poly (arylene sulfide) is 
synthesized by reacting a dihaloaromatic compound and an 
alkali metal sulfide in a polar organic solvent, the curing 
ability of the product polymer may be significantly enhanced 
by introducing a small proportion of a hydroxyl group-­
containing polyhaloaromatic compound to the reaction mixture 
when a conversion of at least 60% has been achieved with 
respect to the dihaloaromatic compound present in the reac­
tion mixture. The product polymer may be advantageously 
employed in various molding, forming or coating processes 
to provide the produced articles with increased strengths. 
The hydroxyl groups introduced into the polymer enable the 
polymer to be modified, if desired.
Patent EP-0328832-A3 (EP)
IPC: B65D59/00
Filed: 1988-12-22
Abstract: The invention provides a protector (2), a protector 
element or a protector assembly for a pipe-end (1) or a joint, 
the protector comprising a shaped body element or 
elements, shaped to mate generally in surface co-operation 
with the joint is additionally provided with at least one 
elastically deformable zone (5) which is capable of being 
strained elastically upon or during the process of making-­
up of the protector on the joint, which zone is capable of 
being an interference fit in its elastically strained 
condition on the complimentary portion of the joint 
irrespective of any dimensional differences that may exist 
due to tolerances or deviations from nominal dimensions of 
the protector and the joint, whereby when the protector is 
made-up to its final position on the joint, sufficient 
elastic deformation is generated in the said zone due to 
the interference between the joint and the protector 
surfaces as to constitute a seal on the joint against the 
ingress of foreign bodies and/or corrosion promoting 
agents across the said zone and/or a barrier for the 
retention of grease or dope.
Patent EP-0286565-A3 (EP)
Title: Power cycle working with a mixture of substances
IPC: F01K23/04
Filed: 1988-04-08
Abstract: A power cycle to operate with maximum temperature above 300°C, working 
with a mixture of water and another substance having lower volatility, 
greater molecular weight and tendency to superheat in the isentropic expan­
sion. Both substances are vaporized in a boiler, in part at variable tem­
perature, and expanded in at least one turbomachine (T-I). After the first 
expansion, a heat yielding takes place at constant pressure (RS), wherein 
part of the least volatile substance condenses at variable temperature. 
In comparison with the steam cycle, this new cycle offers higher 
efficiencies because it has, among others, the advantage of increasing the 
average temperature of heat absorption, without intermediate reheating and 
without condensation occurring in the turbine until very low exhaust 
pressures are reached, depending on the proportion of the mixture used. It 
also facilitates, in the case of combining with a secondary cycle of 
refrigerant fluid, the superheating of this fluid, which is especially 
useful in the case of fluids with wet expansion.
