Method and device for generation of compressed product Principal heat exchanger used in cryogenic rectification heats up a product flow supplied with a pump and consisting of liquid saturated with oxygen or with nitrogen, and therefore, a compressed product flow is created. Layers of the principal heat exchanger are made so that reduction of heat transfer surface provided in the principal heat exchanger for heating of the product flow supplied with the pump occurs at the point at which temperature of the product flow supplied with the pump either exceeds critical temperature or condensation temperature of such a flow. Reduction of heat transfer surface leaves sections of the layers, which are able to heat or cool another flow that is used in connection with cryogenic rectification. Such other flow can represent a cooling agent flow that provides for use of additional cooling to increase production of liquid products. |

Safety strap protection system Strap protection system includes overlay part and protection element. The overlay part features first surface and second surface. The first surface of each overlay part can interact with user body part. The second surface of each overlay part features first guide channel and second guide channel. The first guide channel features protruding parts preventing contact of a strap in the first channel with cross-lap in the second channel. Each protection element features a protruding part. Each protection element is connected to relevant overlay part so that protruding part of the protection element is matched with respective first guide channel of respective overlay part thus forming first guide passage for a first strap. Each protection element protects the first strap running directly in the guide passage from wear and tear. The same protective element forms second guide passage for another strap. First guide passage for the first strap and second guide passage for the second strap formed by respective guide channels cross each other. |

Method and line for fabrication of insert for multilayer film and multilayer film with insert Invention relates to the method and line for fabrication of insert for a multilayer film, to the multilayer film itself, in particular to the inserts for further comprising into the smart card, where the film substrate with several electronic devices placed on it and conjugated with each other is fed to the image reader, which allows to obtain a position of an electronic device, as separate object. Meanwhile the laser sensitive levelling film is applied on the film substrate, at first is fed to the device for laser cutting, and the data on the position of the respective electronic devices on the film substrate obtained by the image reader, is transmitted into the device for laser cutting and this device is controlled for making the cut-outs aligned with the positions of electronic elements. The levelling film with cut-outs, and the film substrate in assembly section are connected and, with precise matching having aligned with reference to each other are fixed, forming an insert. Meanwhile, using the laser cutting device for making of cut-outs, and using one more laser cutting device or the marking device for each object or the group of objects on the levelling film a mounting mark is applied depending on the obtained position of the electronic device on the film substrate. |
