Abstract: The invention describes an electrochromic display element in the form of an electrically dimmable mirror, an optical filter having an electrically alterable transparency or a display element which contains an electrochromic liquid between two electrode sheets, where at least one of the electrode sheets is transparent and has a transparent, electrically conductive layer and the transparent electrode sheet has a pattern of strips or grid made of a material having metallic conductivity in order to produce a uniform coloration of the electrochromic liquid.

Abstract: The present invention relates to a device for generating light signals, in particular traffic lights. The device according to the invention contains a housing with at least one opening, which is closed by a plate, the absorption of which can be controlled electrically, there being located in the interior of the housing behind the opening a diffuser element, which reflects incident light through the plate. Preferred switched states of the plate are either black (absorption over the entire spectral region of visible light) and colored transparent (slight absorption in specific spectral regions) or transparent (no absorption over the entire spectral region of visible light). The device according to the invention is used to generate light signals by virtue of the fact that the ambient light strikes the plate and, depending on switched state, is absorbed entirely, partially or not at all by the plate.

Abstract: Electrochromic display device comprising a pair of glass or plastic plates or plastic films of which at least one plate or film or both plates or films is/are provided on one side each with an electrically conducting coating. At least one plate or film and its conductive coating is transparent. On at least one of the two plates or films, the electrically conductive layer is divided into separate segments which are individually connected to a power source and each has an electric lead from the edge of the device. The plates or films are joined via a sealing ring on the sides on which they are conductively coated. The volume formed by the two plates or films and the sealing ring is filled with an electrochromic medium. The electric leads to the segments are electrically insulated from the electrochromic medium.

The device consists of a pendulum having a free end which is suspended so as to be movable about an axis, characterized in that a holding device for the ball is located at the free end of the pendulum shaft and can release the ball in response to an electrical signal.

Abstract: The present invention relates to a process for producing and correlating light microscope images and spectroscopic data resolved according to wavelength of a sample by scanning individual elements of the sample surface to be imaged once or twice with a confocal scanning light microscope, launching a portion of the light from the imaging beam path into a spectrometer and correlating the image data with the spectroscopic data by storing the spectroscopic data in a two-dimensional area, with one dimension being used to store the measured spectrum of the individual elements and the second dimension being activated by means of the light intensity diffusely reflected by the scanned elements or by means of a criterion obtained from the total data of the sample image by image processing. The advantage of said process is that the potential of a confocal scanning light microscope and of the various spectroscopic processes may be fully exploited.

Abstract: In a hydraulic driving device for an electric pressurized-gas switch, the piston-cylinder systems are responsive to pressure from a hydropneumatic pressure accumulator. The driving device is equipped with a hydraulic pump which feeds several pressure accumulators and is controlled by pressure monitors, and with a gas monitoring device for the pressure monitors. For solving the problem of carrying out indirect gas monitoring while feeding several pressure accumulators by one hydraulic pump instead of direct gas monitoring, there is provided at least one threshold switch for measuring the feed pressure of the hydraulic pump as part of the gas monitoring device. By feeding the pressure accumulators which takes place sequentially in time and is controlled on the one hand by the gas monitoring device and by the pressure monitors on the other hand, it is possible to establish a correlation specific as to the pressure accumulator of the gas loss signal delivered by the threshold switch.
