Title: Test tubes and test strips with electrically fixed indication
Inventor: VLCEK BOHUSLAV DR
IPC: G01N27/447
Filed: 1983-09-05
Abstract: Solutions of various substances can be titrated very simply by allowing them to rise by capillary forces in a transparent tube (or in an impregnated paper strip) filled with a little soluble titrant. This produces a zone which has a different colour and whose length indicates the concentration. A disadvantage is that the slow saturation has to be monitored. A reading which is too late gives incorrectly high results because the boundary of separation moves continuously as a consequence of the test substance diffusing. It has now been found that this can be prevented (in the case of ions) if the tubes or paper strips are connected to a direct-current source, for example by means of a sheet-metal cap and a wire immersed in the solution. At the instant of impregnation, the electrical circuit closes, and the test ions migrate away from the boundary of separation, which becomes immobile. The required potential gradient is >/= 1 V/cm. A detailed description is given of the determination of chloride using tubes containing Ag2CrO4 on polyamide. Current-free monitored application of the same is also possible.

Patent DE-3406694-A1 (DE)
Title: Method and device for reading characters by machine
Inventor: GLEICH WERNER DIPL ING
IPC: G06K9/64
Filed: 1984-02-24
Abstract: The invention relates to a method for recognising characters of a font, scanned by means of a sensor of a reader. The scanned and stored signal values, which originate from the individual characters, are compared with the individual characters of nominal signal values allocated to the script in a character recognition system, and the correspondence of the measured signal to one of the nominal-value signals is determined. To check the correspondence of the character read to one of the characters of the font and to improve it, this first classification step is repeated at least one further time with slightly different function values of the signal curve which correspond to a raster of abscissa values slightly shifted along the abscissa axis, and it is checked whether the correspondence has become better or worse. A number of repetitions of such classification attempts is carried out until a desired, optimum correspondence has been achieved (Fig. 4). <IMAGE>

Patent DE-3409856-A1 (DE)
Title: Monitoring element for image-transmitting methods, in particular for reproduction engineering and printing engineering
Inventor: WERNER GERHARD
IPC: G03F1/00
Filed: 1984-03-17
Abstract: The invention relates to a monitoring element for image-transmitting methods, in particular for reproduction engineering and printing engineering, consisting of a support material (e.g. test film) having wedge-shaped lines and slits. Because of undercutting effects, dimensional changes to the pixels (e.g. raster points) occur during image transmission. These changes in dimension - which have the effect of changing tonal values - can be measured by means of suitable microscopes, but this is very troublesome for production, complicated and time consuming. The monitoring element of the type according to the invention permits simple, rapid, reliable and continuous measurement and evaluation of the changes in dimension of the pixels to be transmitted, as well as of the dissolving power, the scattering behaviour and the exposure latitude of transmission techniques and information receivers. Depending on the type and extent of the undercutting effects, the wedge-shaped lines and slits are reproduced differently, as a result of which it is possible to derive a measure of the changes in dimension. The changes in length of the wedge-shaped lines occurring due to undercutting effects lead to changes in tonal value which are clearly perceptible visually, as a result of which microscopic enlargements are rendered superfluous; the values can be read off even with the naked eye, but at least using a magnifying glass or a filament counter.
Patent DE-3409872-A1 (DE)
Title: Process and device for cleaning the surfaces of filter media
Inventor: KAEPPELER GERHARD DIPL ING
IPC: B01D46/00
Filed: 1984-03-17
Abstract: The invention relates to a process and to a device for cleaning the surfaces of filter media by compressed air blasts. As Figure 1 shows, a Venturi nozzle is integrated into the conventional compressed air reservoir assigned to the filter housing, which Venturi nozzle produces an increase in velocity of the precompressed air. The increased velocity leads to the entrainment of secondary air from the clean air chamber of the filter housing into the main Venturi nozzle.   The pressure pulse units having an integrated magnetically-controlled valve and central Venturi nozzle situated adjacently produce the compressed air reservoir. The upstream Venturi nozzle has a relatively moderately constricted first part and relatively moderately expanded diffuser part. <IMAGE>
