Patent EP-0195194-A2 (EP)
Inventor: SCHLICK HORST
IPC: F02D41/24
Filed: 1986-01-24
Abstract: In a device for the time-controlled activation of electromagnetically actuable fuel injection valves of internal-combustion engines, the injection electronics provided open the fuel injection valve by means of a current pulse as a function of a control variable, the air quantity. Since the quantity of fuel metered in for a current pulse of predetermined duration depends on the characteristic of the fuel injection valve, i.e. deviations from a setpoint characteristic, an electrical resistor (16) is arranged on each fuel injection valve (1-14), the said resistor being dimensioned in proportion to the characteristic quantity, or deviation from the setpoint characteristic quantity, of the fuel injection valve. The resistor is connected to the injection electronics (18, 22) for influencing the injection time, in order to compensate the deviations of the characteristic from a setpoint. <IMAGE>

Abstract: The invention relates to a method and an apparatus for frequency selective irradiation of biological materials and particularly tissues, cells and/or cell components of living organisms, in particular of human and animals, by irradiating a component element of the target material at the corresponding Mössbauer absorption frequency. The component radiation absorption at the Mössbauer absorption frequency is thus enhanced many times over the absorption of the surrounding material having a different Mössbauer absorption frequency. The energy thusly absorbed by the target material component is converted to and remitted as Auger electrons, which provide intranuclear radiation resulting in lethal double strand breaks in the DNA molecules of the target tissue. The irradiation is administered in frequency and material selective modes of treatment, and may be combined with conventional chemotherapeutic agents to provide a further enhanced treatment modality. Moreover, the source frequency can be adjusted to enhance the killing effect. The method of apparatus according to the present invention are useful in combination with naturally occurring or administered pharmaceutical stable isotope absorbers, having significantly reduced side effects by comparison to conventional chemotherapy or radiation therapy. 
<??>The method and apparatus according to the invention can be applied for selective radiation therapy providing selective tissue damage or necrosis, in particular for cancer therapy, and for differentiating between diseased and normal tissues.

Abstract: A whole blood aggregometer of red blood cells (RBC) consists of a transparent tube containing freshly drawn heparinized blood, and a densitometer head which is attached to the tube. The densitometer head consists of a light source and a light detector to monitor changes in optical density of the blood in the tube. The blood in the tube is first subjected to rapid flow with a solenoid, so that the wall shear rate of the blood approximated to 500 s⁻¹. The shear gave rise to a rapid increase in optical density of the blood due to dispersion of the blood corpuscles. The blood is then brought abruptly to a full stop. After the flow had stopped, the densitometer head reveals a gradual decrease in optical density in association with RBC aggregate formation. The resultant pattern is termed as an "RBC aggregogram". The RBC aggregogram exhibited a quasi-exponential decay in its initial part, which was followed by an asymptotical decrease. A mathematical procedure is employed to calculate the rate constant of the initial decrease from the two values on the RBC aggregogram at 10 s and 20 s. The rate constant k₁₀ was 0.192 + 0.028 for feline blood, and 0.129 + 0.012 for human blood. The RBC aggregation rate varied linearly with the hematocrit below 40%.

Abstract: An improved method is proposed for continuous optical transmission measurement particularly with a view to determining the concentration of different molecular compounds in liquids and gases, in which the optical radiations of at least four sub-beams are used and the emission values of the radiation sources are maintained at constant values. A system using this method is designed so that the different wavelength ranges of the radiation sources are used for balancing out interference effects in that the radiation of one wavelength range is integrated until a predetermined integral value is reached and the integral of the radiation of the other wavelength range obtained over the same time interval is used as the measured value.

Abstract: A method and a system for radio direction-finding by measuring the Time of Arrival (ToA) of the leading edge of signals from a distant source at two relatively closely spaced receiving elements. In order to give a good degree of immunity to multipath, the times at which the instantaneous detected amplitudes of the received signals first exceed a minimal threshold value such that received signals can be satisfactorily distinguished from noise is measured in such a manner that the measured time is not affected by multipath which involves more than a few metres additional path length for the indirect, delayed signal. A suitable timing circuit is disclosed. 
     By making ToA measurements on three coplanar, non-collinear receivers, directions of incidence in three dimensions can be determined. 
     A method and a system using both ToA and phase-difference measurements can provide the accuracy of interferometry but be simpler and cheaper.

Abstract: A system to prevent, retard or reverse the decomposition of silicon carbide articles during high temperature plasma sintering. Preferably, the system comprises sintering a silicon carbide refractory or ceramic green body in a closed sintering environment, such as a closed tube, with strategic placement of the plasma torch or torches, exhaust outlet and tube. As sintering proceeds, a silicon vapour pressure builds up within the tube, retarding the decomposition of the silicon carbide body. The plasma torch, exhaust outlet, and tubes are positioned so that buoyant convective flow is maximised to increase the heat transfer and energy efficiency. In another embodiment, a "sacrificial" source of silicon carbide is placed into the sintering furnace. The silicon carbide in the sacrificial source starts to decompose before the silicon carbide refractory or ceramic article, creating a supersaturated atmosphere of silicon vapour species in the furnace. This prevents, retards or reverses the silicon carbide decomposition reactions and thus maintains the integrity of the refractory or ceramic article being sintered. Preferably, the sacrificial source is placed in a closed sintering environment along with the silicon carbide articles being sintered.
