Patent EP-0296551-A3 (EP)
IPC: G05D7/01
Filed: 1988-06-22
Abstract: An electromagnetically operated valve 
assembly and flow control capsule (50) 
therefor. The valve has a single inlet (18) and 
dual outlet with flow to one outlet 
regulated by the flow control capsule 
and the flow to the second outlet 
unregulated. The flow control capsule 
is formed of plastic with an integrally 
hinged snap-lock cover for retaining a pressure responsive elastomeric 
flow control washers in the capsule. The capsule has an annular 
tapered rib (72) formed about the outlet (70) 
for sealing the capsule about the wall 
of the valve passage (19) into which the capsule discharges flow.

Title: Ferroelectric smectic liquid crystal device
IPC: G02F1/141
Filed: 1988-09-19
Abstract: A ferroelectric smectic liquid crystal device 
having an improved impact resistance and an improyed 
contrast is provided by using a pair of substrates (11a,11b) 
provided with uniaxial alignment axes which are 
parallel and identical in direction with each other. A 
ferroelectric smectic liquid crystal (15) is disposed 
between the pair of substrates (11a,11b) so as to assume a 
higher-temperature alignment state and a lower-temperature 
alignment state on temperature decrease in 
its ferroelectric smectic phase placed in a bistable 
alignment state. The ferroelectric smectic liquid 
crystal (15) is further placed in the lower-temperature 
alignment state which is characterized by having an 
inclination of forming a connected pair of a lightning 
defect and a hair pin defect coming after the 
lightning defect.

Title: Process for the preparation of aqueous polymer dispersions
IPC: C08F2/22
Filed: 1988-12-13
Abstract: The process involves the free-radical polymerisation of
 (a) from 50 to 100%, based on the weight of all the monomers, of C1- C20-alkyl (meth)acrylates,
 (b) from 0 to 20%, based on the weight of all the monomers, of polyolefinically unsaturated monomers and
 (c) from 0 to 30%, based on the weight of all the monomers, of further monoolefinically unsaturated monomers,
 in aqueous emulsion in the presence of a preformed, water-dispersed solution copolymer (A) made from
 (I) from 1.5 to 15% by weight of monomers containing 3 to 10 carbon atoms and one carboxyl or carboxylic anhydride group,
 (II) from 30 to 98.5% by weight of C1-C20-alkyl acrylates or methacrylates,
 (III) from 0 to 60% by weight of vinylaromatic compounds,

Patent EP-0276953-A3 (EP)
IPC: G01N21/55
Filed: 1988-01-21
Abstract: A dewpoint meter has a sensor comprising a mirror 
(1) situated in a chamber (2) through which gas, the 
dewpoint of which is to be measured is passed through an 
inlet port (3) and an outlet port (4). The mirror (1) is 
cooled by a Peltier effect heat pump (11) and the 
formation of condensation on the mirror as it is cooled 
is detected by a detector comprising a light emitting 
diode (7) and a photodiode (8). The temperature at which 
condensation occurs, which is the dewpoint of the gas, is 
measured by a thermometer. Instead of transferring the 
heat from the heat pump (11) directly to a heat sink (13) 
as is usual, a heat pipe (12) is interposed between the 
heat pump (11) and the heat sink (13). This avoids the 
necessity for having the heat sink closely adjacent the 
mirror and thus avoids errors caused by heat from the 
heat sink affecting the temperature of the mirror.

Title: Porous membranes of sinterable refractory metal oxides or silica
IPC: B01D71/02
Filed: 1988-11-03
Abstract: The invention relates to porous membranes made of 
sintered silica or refractory metal oxides, e.g. alumina, 
titania, zirconia, tungsten oxide, etc., and to a process 
for their formation. The membranes are formed by dispers­
ing a powder of the metal oxide or silica in an organic 
polymer. The relative amount of silica or metal oxide to 
polymer is such that, after the polymer has been carbonized 
in a subsequent step, there is a stoichiometrical excess of 
the oxide to carbon. The solution is then shaped to form a 
desired thin membrane, and the polymer is then carbonized 
by heating it in a non-oxidizing atmosphere. The resulting 
oxide/carbon product is heated to a temperature at which 
(a) the carbon reacts with the oxide to form a volatile 
sub-oxide and carbon monoxide and (b) the remaining 
(unreacted) oxide particles sinter together. The heating 
is carried out in a non-oxiding atmosphere containing 
either no nitrogen whatsoever, or an amount of nitrogen 
less than that which results in the formation of a 
non-porous product. The sintered membranes can be used, 
for example, as filters and catalyst supports and have 
good strength and controlled porosity.

Title: 3d image reconstruction method and apparatus for placing 3d structure within common oblique or contoured slice-volume without loss of volume resolution
IPC: G06T15/08
Filed: 1989-06-15
Abstract: Variable voxel shifts required for shifting a 3D structure into a common oblique or contoured slice volume based on an existing 3D image are achieved by effecting variable f(x,y) phase shifts in corresponding frequency domain data parallel to a selected axis dimension and then reconstructing a new three-dimensional image having the 3D structure all located within a common oblique or otherwise contoured slice volume such that it may viewed in a single planar image display without loss of volume resolution. Equivalent convolution processes within the spatial domain may also be employed. Oblique or curved reconstructions can thus be made using either originally acquired frequency domain data (used to construct the original image) or frequency domain data obtained by inverse Fourier transforming the available spatial domain data of the images themselves.

Title: A read-after-write magnetic head
IPC: G11B5/11
Filed: 1989-07-31
Abstract: Thin strips (15a) of ferrite are inlaid into the surface of a 
read-after-write magnetic head (10) between the read (13) and write (12) 
gaps for reducing feedthrough. The ferrite shields extend across a 
substantial portion of the tape-engaging surface between the read and 
write gaps. Further reduction of feedthrough is achieved by inlaying 
additional shielding (15b) outboard of the read gaps (13). The shielding 
does not encircle individual read or write gaps, but may extend across 
tracks in a multitrack head. The ferrite shielding absorbs magnetic flux 
which otherwise strays from the magnetic cores. Material and 
manufacturing costs are maintained low because the shields are small and 
simple in geometry.

Filed: 1989-09-04
Abstract: A process for preparing a dispersion of a filler eg melamine, 
urea or borax in a dispersion or graft polymer polyol is provided. 
The process comprises (1) dispersing the filler in a suitable 
basestock (eg a polyether polyol) and (2) thereafter using this as

step may be for example (1) the reaction product of a polyamine, 
hydrazine or hydrazide and an isocyanate (PHD polymer) or (2) the 
reaction product of an olamine and an isocyanate (PIPA polymer). 
Alternatively styrene and acrylonitrile can be graft polymerised in 
the basestock in step (2). The new dispersion or graft polymer 
polyols containing dispersed filler are useful in the manufacture of 
fire resistant polyurethane foam for eg furniture applications.

Title: Method for the reductive methylation of primary amines
IPC: C07B61/00
Filed: 1989-12-18
Abstract: Permethylated amines particularly pentamethyldi­
ethylenetriamine, are prepared by a two stage reductive 
methylation of amines containing at least one primary 
amine group. In the first stage, only a sufficient 
amount of formaldehyde to monomethylate the primary 
amine groups present is continuously fed to the reaction 
system at a high flow rate, and thereafter the flow rate 
of the formaldehyde is substantially reduced for the 
second stage in which methylation is completed The 
production of by-products is substantially reduced and 
preparation times are significantly shorter in 
comparison to processes where the formaldehyde flow rate 
remains constantly high for the entirety of the 
reaction.
