Abstract: The subject of the invention is a multilayer photovoltaic panel with increased solar radiation energy to electric energy conversion surface which is characterised in that it comprises a lattice subassembly (1, 16, 23, 34, or 39) or at least one the chamber subassembly (44, 49, 54?, or 60?), in which the component photovoltaic modules (6 and 7) or (18 and 20) or (24 and 30) or (35) or (40) or (45) or (50) or (54) or (60) are connected inseparably with a photovoltaic layer (3) or (11) of the perforated support plate (2) or (17), whereas the perforated support plate (2) constitutes a plate-shaped stiffening element (14) with a single photovoltaic layer (3) or the perforated support plate (17) constitutes a plate-shaped stiffening element (14) both of the two surfaces of which are provided with photovoltaic layers (11).

Abstract: A bumper for vehicles mounted to the front or to the rear of a vehicle comprising a bumper beam made of a plastic which is characterised in that the bumper beam (2) together with a shield (3) of a lamp (4) constitutes a single monolith made of a plastic with translucency from 10% to 100%.

Abstract: The structural node of tight separable joint of bottle neck with its threaded screwed cap made of plastic includes a cylindrical neck (1) of bottle (2) and a screw cap (3) screwed onto outer thread (4) of the neck, the cap being provided with an inner thread (5) and an inner sleeve (8) joined inseparably with bottom (6) of the cap, whereas outer surface of the sleeve has at least one annular sealing tongue (11 or 13) end of which fits tight to cylindrical surface (12) of the neck (1) or end of the at least one annular tongue (11 or 13) is set tightly in eat least one circumferential groove (14 or 15) provided on inner cylindrical surface (12) of the neck (1). Moreover the cap (3), on inner surface of its sleeve portion (10), has annular offsets (17) situated above its thread (5) ends of which are tightly set in circumferential grooves (18) provided on outer surface of the neck (1) above its outer thread (4) and opposite said offset ends.

Abstract: A method of electronic verification of reliability of goods introduced to the trade turnover and of transmission of data about the origin of the goods according to the invention is characterised in that owner of the brand (1) enters into a database (4) installed on his desktop computer (2) and with the use of said computer, generates an appropriate number of unique and unrepeatable sets of codes corresponding to the quantity of goods introduced to the trade turnover, and then the sets of codes in the computer are encrypted with the use of an encrypting algorithm (3) and transmitted, in the binary form, with the use of the database management system (5) managing said database and a data carrier (6), to the database (4) installed on the computer from where the database encrypted with the use of said database management system is transmitted to a database (8) installed on a desktop computer (9) operated by manufacturer (7) of the goods.

Abstract: The subject of the invention is a device with a reciprocating motion mechanism enabling the conversion of its moment of inertia into rotational speed or rotational speed into moment of inertia, characterised in that on the rotating shaft (11) there is a releasable mechanism (2) of reciprocating motion in two perpendicular directions, including two circular discs (3 and 4), tiled in parallel, with profiled notches (7 and 8) on their surfaces, whereby both discs are connected with each other by bolts (10) and have a releasable connection with the rotating shaft (11) and between each pair of profiled notches (7 and 8) of both discs there are upper connectors (14) of the upper ends of each pair of opposite moving arms (15), having an articulated connection with each other, of which the other ends also have an articulated connection with the two ring connectors (17) of two hydraulic actuators (18), which have a releasable connection with this shaft, whereby all upper connectors are equipped with functional compone
