Patent EP-0320255-A3 (EP)
Title: Polarimetric optical frequency domain distributed strain sensor and method
IPC: G01L1/24
Filed: 1988-12-08
Abstract: An optical frequency domain distributed strain 
sensor for determining the strain distribution along an 
optical fibre (44) includes an optical source (32) which 
provides a polarization controlled optical interrogation 
signal having a frequency varying in a recurring linear 
manner. The interrogation signal is injected into the 
fibre embedded within a composite structure (46) which 
places the fibre under strain. A portion of the 
interrogation signal is backscattered from the sensing 
fibre (44) as a consequence of the strain experienced by 
the fibre and is mixed with a reference signal to produce 
beat frequency signals. The frequency of the beat signals 
is directly related to the position of backscatter in the 
sensing fibre while the amplitude of each beat frequency 
signal is directly related to the integrated 
strain-induced birefringence up to the backscatter point. 
An in-line fibre polarizer and an associated controllable 
polarizer (38,40) control the polarization state of the 
interrogation signal in the sensor fibre (44) to provide 
zero point sensitivity compensation and controllable 
testing for ambiguous strain points.

Abstract: U-shaped gripping bars (5) are mounted by their end portions in block-shaped or cuboid swivel bearings (8) at the upper edge of a storage and/or transport container (1) on two opposite sides of the container. Said gripping bars (5) can be folded down against the outside of the walls for placing several containers (1) one inside the other and can be swivelled inwards to form stacking rests for placing the containers (1) one on top of the other.

Title: Compensated magneto-resistive read head
IPC: G11B5/11
Filed: 1989-01-12
Abstract: A read/write head (13) for a hard 
disk provides both a magneto-resistive 
read function and an 
inductive write function in a common gap. 
The inductive write function is provided 
by a current carrying coil (27) which 
is magnetically coupled to top and 
bottom shields (19, 21) or pole tips which in 
turn induce the magnetic fields required 
for writing on the disk. Mutually 
biasing magneto-resistive read sensors (23, 25) 
are located between the shields, 
which serve to improve the resolution 
of the read function. During a read 
operation, read/write circuitry (11) 
maintains a current in the coil which 
cancels, at least partially, magnetic 
fields induced by sensing and bias 
currents in the magneto-resistive 
heads which might otherwise perturb 
information stored in the medium. 
This arrangement provides a read/write 
head with improved read/write 
resolution as required by emerging high 
density storage media in compact formats.

Filed: 1989-01-12
Abstract: In a method of recording a data signal on an 
optical card (11) having a photosensitive layer applied on a 
metal layer, a number of light beams are emitted from a 
number of light sources (15), such as semiconductor laser 
diodes or thin film electroluminescent elements, each 
light source being selectively driven in accordance 
with the data signal to be recorded, and the light beams are 
simultaneously made incident upon the photosensitive 
layer via a projection optical system such as optical 
fibers and lens, while the optical card is moved in a 
longitudinal direction of the optical card.  
The recording light beams are aligned in a width 
direction perpendicular to the longitudinal direction. 
In this way optical cards can be manufactured quickly 
and cheaply in comparison to previously-proposed methods.

Title: Method of recognizing patterns
IPC: G06T7/60
Filed: 1989-07-31
Abstract: In a method of identifying an object from a 
digitized image that is particularly applicable to 
the classification of aircraft, the digitized image 
(152) of an unknown object is represented as a set 
of radial vectors (150₁, 150₂, ..). The vectors 
(150) are normalized and then compared with a library 
(18) containing normalized digitized images of known 
objects. The unknown object is thereby identified 
as being similar to the known object corresponding 
to the library image most closely matching the image 
of the unknown object. A score for the comparison 
of the unknown object silhouette with a known 
silhouette is obtained by subtracting the radial 
vectors of the known silhouette from those of the 
unknown silhouette, and summing the differences. 
The closest match is the smallest sum of difference.

Title: Linear viscoelastic aqueous liquid automatic dishwasher detergent composition
IPC: C11D3/12
Filed: 1990-04-11
Abstract: Automatic dishwasher detergent composition is formulated as a linear viscoelastic, pseudoplastic, gel-like aqueous product of exceptionally good physical stability, low bottle residue, low cup leakage, and improved cleaning performance, Linear viscoelasticity and pseudoplastic behavior is attributed by incorporation of cross-linked high molecular weight polyacrylic acid type thickener. Potassium to sodium weight ratios of at least 1/1 minimize amount of undissolved solid particles to further contribute to stability and pourability. Control of incorporated air bubbles functions to provide the product with a bulk density of about 1.35 to 1.40 g/cc which roughly corresponds to the density of the liquid phase. Stearic acid or other fatty acid or salt further improves physical stability.

Title: Method for determining the endogenous thrombin potential of plasma and blood, and also a kit or use in said method
IPC: C12Q1/56
Filed: 1990-09-21
Abstract: A method for determining the endogenous thrombin potential (ETP). which shows how much and for what length of time thrombin has been active in a sample of clotting blood or plasma. The ETP can be used for determining the effectiveness of treatment with antithrombotics of any type. Said ETP determination comprises adding to said sample a thrombin substrate, an activator of thrombin formation, a preparation of proteaseinhibitor and if desired a pharmaceutical for analysis . The thrombin substrate is preferably selected to not completely consume the amount of thrombin generated in the sample, to have a rate of conversion of the substrate which is proportional to the amount of thrombin present and to have a measurable conversion product resulting from the conversion by thrombin. Determination of the amount of conversion product leads to determination of the ETP. The choice of activator determines whether the effect is measured on the intrinsic or extrinsic clotting system, making it possible to determine the effect of the pharmaceutical, which is being analysed, on various parts of the clotting mechanism.
