Patent EP-0225632-A2 (EP)
Inventor: ROTHELE STEPHAN DIPL-ING
IPC: G01N1/10
Filed: 1986-12-09
Abstract: The method involves taking a subsample from a main product stream and, by sample separation, obtaining from this subsample an analysis sample to be analysed and a residual amount. To provide a method and apparatus for representative sampling, in terms of time and place, and sample separation to obtain a small analysis sample stream suitable for subsequent on-line sample analysis, the invention provides that sampling and sample separation are carried out continuously in-line in direct succession and, with sampling, a representative subsample stream of up to 1/100 of the main product stream is taken by a rotatably driven collecting head (12) which is arranged at the inlet of a collecting line (30) and the collecting opening (10) of which is at least one circular sector, which can be rotated by its tip about the centre axis of the product stream transport pipe. Immediately after sampling, the subsample stream is continuously separated by a sample separator (60) by up to three powers of ten. The individual samples produced during sample separation are drawn off individually or randomly, combined by a concentrator (71), in such a way that the subsequent analysis can be carried out directly on-line without any appreciably delaying intermediate storage. Various designs of the sampler (9) and the sample separator (60) are explained.

Abstract: The injection system for the load-dependent injection of the fuel into a cylinder of a diesel engine in two partial injections, a pre-injection (V) and a main injection (H), is designed in such a way that, at low loads - under, for example, 20 - 50% of the full load - the injected fuel quantity is not distributed over the pre-injection (V) and the main injection (H). Thus irregularities in the fuel injection at the low total fuel quantities which are required at low loads are prevented. <IMAGE>

Abstract: An apparatus for carting by sputter ion plating comprises a chamber having a gas inlet and outlet for passing gas under low pressure continuously therethrough; a cathode fabricated of coating material or precursor therefor positioned in the chamber; and means for generating a glow discharge within the chamber to sputter cathode material to 'form a coating thereof or of a product obtained therefrom on a substrate also positioned in the chamber. 
     The cathode includes a plurality of projections - (e.g. fins) extending from a surface, their disposition and geometry being such as to increase the effective ion current density in the chamber. In this way, high currents at low voltages and pressures may be I achieved so that the apparatus can be used to coat a large substrate load, possibly at a higher coating rate.

Abstract: During grinding of successive workparts with a superabrasive wheel in a rough grind stage at a high wheel infeed rate and a finish grind stage at a relatively low infeed rate with spark-out stages after each of the rough and finish grind stages, the duration of the spark-out stage after rough grinding is made dependent on the condition of the grinding wheel and corresponds to the time needed for removing workpart material for the reduction of the grinding wheel motor power from the high rough grind level to the lower finish grind level. The duration of the spark-out stage will therefore be variable from one workpart to the next as the condition of the wheel changes. In addition, the interval of wheel retruing or dressing (i.e. number of workparts ground between wheel retruing) is variable as determined by the condition of the wheel. In particular, when the rough spark-out stage for a workpart is completed in a time shorter than a preselected minimum time indicative of a wheel that is in need of retruing. Typically, the occurrence of a drop in wheel motor power from the rough to the finish level during the preselected time interval is sensed and activates a memory circuit to store the fact that the machine needs to be placed in the wheel truing mode.

Abstract: An actuator which carries a magnetic head of a disk memory is moved by a drive motor to seek a track on a disk. The motor is energised by a pair of trapezoidal drive current pulses, which have a lower level or zero power spectrum component at the frequency (f₁) coinciding with the mechanical resonance frequency of the actuator mechanism. Each drive current pulse waveform has a peak plateau period (T<sub>CON</sub>) and a base period (T<sub>ACC</sub>). The ratio of the plateau period to the base period of the trapezoidal waveform is adjusted depending on the length of the seek stroke. A constant velocity region in which no drive current flows into the motor between the first positive trapezoidal current pulse and the second negative trapezoidal current pulse is provided if the seek stroke is long.

Abstract: Um apparativ bedingte Schwankungen bei der periodischen Bestimmung einer Meßgröße durch Differenzbildung zwischen einem durch die zu messende Größe gegenüber einem Ursprungssignal veränderten Meßsignal und einem durch die zu messende Größe gegenüber dem Ursprungssignal unbeeinflußten Referenzsignal auszuschalten, wird für jede Bestimmung der Meßgröße ein Grundsignalpegel (I) als Differenz zwischen dem Referenzpegel (X) und einem Nullpegel (Y) bei fehlendem Ursprungssignal bestimmt und dann sowohl jeder aktuelle Referenzsignalpegel (A) als auch jeder Meßsignalpegel (B) mit dem zuerst gemessenen Referenzsignalpegel (X) kompensiert. Durch Verstärkung der kompensierten Referenzsignale (A') und Meßsignale (B') vor der Differenzbildung und Normierung der aus diesen Signalen gebildeten Differenz (E) auf den Grundsignalpegel (I) kann eine hohe Genauigkeit auch bei nur geringen Abschwächungen des Meßsignals durch die zu messende Größe erreicht werden (Fig. 2).

Abstract: In an analog test system for testing integrated circuit chips, AC level calibration is achieved by adding a minimal number of new elements and more fully utilizing elements existing in the system. A reference voltage from an existing precision DC power source is fed to an analog switching device. A control signal is also fed into the analog switching device from an existing digital signal generator. Based on the control signal, the analog switching device converts the reference voltage into a rectangular waveform signal, which is then digitized. The digital signal is analyzed, and data from the digital signal is compared with reference data, and the AC level error, if any, is determined. AC level calibration is based on this error.

Abstract: The invention relates to a process and a device for determining the wheel loads of fast-moving rail vehicles from the measurement signal of at least one measuring point by means of at least one strain gauge which is fastened to the stem of a rail level with the neutral fibre and of which the main effective direction for measuring the compression of the stem during the overrun of the wheel is arranged orthogonally relative to the neutral fibre. The measurement signal is picked up above a threshold value and converted into digital measurement values and a compensating function is formed from successive measurement values, the wheel load being determined from the maximum of this function and the threshold value. To reduce the outlay for data processing, the digital measurement values occurring will be fed individually and in succession to a recursive low-pass filter of at least the second order, the current filter value being stored and the wheel load being determined from the maximum filter value and the threshold value. <IMAGE>

Abstract: Molded articles are produced in a two-stage process. In the first stage, an organic polyisocyanate is reacted with an organic compound containing at least two epoxide groups (NCO: epoxide equivalent ratio of 1.2:1 to 500:1) in the presence of a tertiary amine catalyst. This reaction is stopped when no more than 65% of the isocyanate groups have reacted by adding an alkylating sulfonic acid alkyl ester of methyl iodide and/or of dimethyl sulfate in an amount equivalent to the amount of tertiary amine catalyst present. A latent catalyst capable of being activated by heat is subsequently added to the intermediate product and the resultant mixture is heated in a mold to complete the crosslinking of the intermediate product and to form the molded article.
