Patent EP-0278677-A3 (EP)
Title: Sampling device
IPC: G01N1/04
Filed: 1988-02-04
Abstract: A sample of a biological tissue and/or fluid, particularly plant sap, may be taken by placing biological tissue such as a leaf 13 between a layer 7 which is adsorbent for detectable biological material (for example nitrocellulose) and a substrate 3 and applying pressure to urge the adsorbent layer and the substrate towards each other, thereby causing detectable biological material to be adsorbed on the adsorbent layer. The invention thus provides a convenient method of obtaining, securing and transporting small samples of plant sap or other fluid or tissue to the laboratory for such purposes as analysis for plant viruses and other organisms.
Patent EP-0282251-A3 (EP)
Title: Fluid transducer
IPC: G01N11/16
Filed: 1988-03-07
Abstract: A transducer for measuring a parameter of a fluid, such as density or viscosity, comprises two generally parallel tines extending from a common yoke, forming a tuning fork adapted to be immersed in the fluid. The tines are excited to vibrate resonantly and in anti-phase by one or more piezo-electric exciting elements, which are housed in one or more cavities within the tines or the yoke. The vibrations are sensed by one or more similarly-housed piezo-electric sensing elements. The tines are shaped to enhance their sensitivity to the parameter to be measured: for example they are provided with re-entrant surfaces to enhance density sensitivity, or elongated in the direction in which they vibrate to enhance viscosity sensitivity.
Patent EP-0283249-A3 (EP)
IPC: G06F3/044
Filed: 1988-03-15
Abstract: A conventional three-electrode wedge-and-strip pattern in a 
digitizer tablet surface is used with a conventional cursor or 
stylus. A phantom cursor electrode is located at predetermined 
coordinates of the active area of the digitizer tablet beneath 
the X, Y and balance (B) electrodes and separated therefrom by a 
layer of dielectric material, preferably an air gap. Prior to 
use of the digitizer apparatus, the phantom cursor electrode is 
electrostatically coupled to the X, Y and B electrodes in order 
to obtain data signals representing the phantom cursor's measured 
coordinates without compensation for resolution distortion. A 
microprocessor produces a correction factor using the data 
signals and the predefined coordinates of the phantom cursor 
electrode, which correction factor is applied in normal use to 
compensate for resolution distortion resulting from the 
unavoidable gaps between the X, Y and B electrodes. Also raw 
measured data obtained from the electrostatically coupled 
electrodes is adjusted to compensate for environmental and 
inherent noise and an offset corresponding to the difference in 
the reference potentials of the integrator and comparator.

connected, for example, through a conductive pin (101) 
by a pressing arrangement (23) in the other end of the 
electrical contact.

Patent EP-0390175-A3 (EP)
IPC: A61B5/055
Filed: 1990-03-29
Abstract: A multi-echo NMR imaging method of obtaining 
images separated from each other with respect to two 
kinds of chemical shifts, typically, a fat image and a 
water image, includes performing the measurement of an 
object to be examined through a multi-echo sequence 
(Fig. 1A-1F) in which phase differences of ϑ₁ ≠ nπ and 
ϑ₂ = 2nπ (n = ±1, ±2, ---) are respectively produced 
for first and second echoes between two kinds of spins to 
be separated from each other, deriving first and second 
complex images {equation (2)} from the first and second 
echoes, respectively, correcting the phase of the first 
image by converting a phase distribution of the second 
image into a distribution of phase error components 
contained in the first image which are caused by a static 
magnetic field inhomogeneity, and obtaining separative 
images for the two kinds of spins from real and imaginary 
parts of the first image corrected.

Filed: 1990-04-17
Abstract: A method for the open-loop and closed-loop control of an internal combustion engine (1) in which a digital binary output signal (b) is calculated in a computing device as a function of operating variable signals, such as for example the engine speed (n), the accelerator position, the engine temperature etc., said calculated binary signal is converted into an actuation signal (s) which consists of pulses of a constant amplitude, the overall duration of the actuation signal within a clock period being proportional to the value of the binary signal and this actuation signal being used to control an electromechanical actuator. In this process, the actuation signal is divided up within each clock period depending on the value of the binary signal (b) into individual pulses whose overall duration is proportional to the value of the binary signal (b) and the individual pulses are distributed essentially evenly within each clock period. In addition, a device for carrying out the method is disclosed. <IMAGE>

Patent EP-0507568-A3 (EP)
Title: Automatic charge cut-off circuit and application
IPC: H02J7/00
Filed: 1992-04-01
Abstract: A battery charging circuit is provided with a thermal cut-out (TSI) whose normally closed contacts are in series with the main terminals of a thyristor (SCR1). The thyristor is switched ON on commencement of battery charging by the charging of a capacitor C1 (which remains charged even when the contacts of cut-out TS1 open as a result of the battery temperature rising on completion of charging). Consequently thyristor SCR1 remains latched OFF even if the contact of cut-out TS1 close, and can only be turned ON again by disconnecting battery B1, which enables capacitor C1 to discharge via a diode CR1.
