The invention relates to systems for determining the dimensions and surface relief of micrometre-sized spatial objects by generating a composite image of the examined spatial object using the microscope. The invention aims to improve the detection quality when object is transparent or partially transparent or when the surface of the object is soft and/or easily damaged. The examined three-dimensional micrometre-sized object is photographed from above with a microscope, and the contour of the micrometre-sized object is determined by the sensor with an electrode for measuring electrochemical properties between the sensitive surface of the mentioned electrode and the surface of the micrometre-sized object at each scanning point, thus determining the height of object under investigation and its coordinates at each point at the scanned point. Thanks to the program installed in the computer processor, a general image of the examined spatial micrometre-sized object with its real dimensions and its surface relief is obtained.

The invention relates to the atmospheric cold steam engine for generating mechanical energy through the use of atmospheric pressure and environmental thermal energy or excess of low temperature thermal energy released during production processes. The operating principle of the atmospheric cold steam engine is based on the characteristic of the materials to absorb or release the thermal energy during their transition from liquid to gaseous phases and vice versa. The purpose of the invention is to expand the possibilities of the heat pump by converting the thermal energy collected from the environment into the mechanical energy. The mechanical energy thus obtained can be used for the compressor of the same heat pump or be transformed into another type of an energy (electricity etc.) to be used by consumers in need.

The invention relates to biofilters with biologically activated material, specifically - for biofilters for removing volatile organic compounds, for example, acetone, butanol, toluene, xylene, styrene, butyl acetate, phenol, formaldehyde, etc. from air or gas. The purpose of the invention is to improve the structure of the treatment device, to expand operation possibilities, to increase air treatment efficiency and to reduce costs. A biofilter-adsorber with a capillary charge humidification system, having a polluted air supply duct, filtering charge, humidification system, ventilator blowing polluted air into the filter, systems of maintaining temperature in the biofilter-adsorber is characterised in that the device charge consists of plurality of vertical tubes 20 with porous or perforated walls filled with wood or activated coal granules of 2.0 - 6.0 mm in diameter, mixed with thermally modified wood fibre at the ratio 10:1. Tubes 20 are placed in lines I, II, III, IV, etc., distances between the tubes are 1.0 - 2.0 mm, the lines are installed at the angle of 30 - 45° with regard to the polluted air movement direction, and the distance between the lines does not exceed a tube radius. The tubes at 1/3 of their height from the bottom are submersed in activated liquid, in this way causing capillary humidification of the filtering section.
