摘要:
The subject of the present invention is an energy-saving charge transport system in the press-furnace line with recovery of heat energy and recovery of electric energy. Its objective consists in introducing a rational management of heat energy and electric energy in the charge transport system along the press-furnace route and by means of a well-thought-out arrangement of transport routes and charging elevators, achieving compact dimensions of the whole transport structure. The essence of the energy-saving charge transport system in the press-furnace line is the heat energy recovery in the area surrounding the furnace and recovery of electric energy used to drive transport elevators. Elevator (1) loaded with hot charge (3) moves downwards. Motor (5) acting as an electric current generator brakes motion of elevator (1) and via controller (7) supplies electric energy back to battery (8); when motor (6) lifts elevator (2) loaded with cold charge (4), then, in large measure, it uses the energy stored in battery (8). The energy-saving charge transport system in the press-furnace line may find wide application in industries where consumption of energy in the course of technological process is a significant issue.

The subject of the invention is a drive for an ultra-high-energy pulsatory-rotary mill that can be applied in the laboratory-class equipment. The objective of the invention is the use of the drive for an ultra-high-energy pulsatory-rotary mill which allows to accomplish the three-dimensional milling process in three axes with simultaneous control of amount of the supplied mechanical energy in real time. The rotary-planetary drive comprises an alternating-current motor (1) constituting the rotary motion drive and powered through an inverter (2) connected with the rotary mechanical energy counter (3), and an alternating-current motor (4) driving actuator (5) constituting the pulsatory motion drive and powered by inverter (6) connected with the pulsatory mechanical energy counter (7). Signals from mechanical energy counters (7) and (3) are conveyed to the digital recorder (8).

摘要:
A method of preparing a mixture consists in successive performing of: atomization of fuel in a stream of exhaust gases, introduction during suction or an exchange of the load of an incombustible fuel-combustion mixture to a separate storage space, compression - in a positive-displacement manner without mixing - of the mixture with the air inflowing to the storage space from the working space of the engine, forcing through of the compressed mixture into the combustion chamber before the top dead center of the piston completing the compression strike, and in production of a combustible mixture by mixing with air compressed in the combustion chamber. A piston engine of internal combustion of the mixture produced by the said method utilizes the configuration of a piston (5) and a head (17) separating in the range of the top dead center a combustion chamber (1) and a forcing-through chamber (2). Additionally, it has a storage space (3) connected periodically by a periodically cutting-off mechanism with an exhaust gases passage comprising a device (7) atomizing the fuel. The storage space (3) is shaped so that it connects in a through manner the forcing-through chamber (2) and the combustion chamber (1) separated in the range of the top dead center of the piston. The storage space (3) can be situated in a head (17) or in the head of the piston (5), whereas the cut-off mechanism can be a pressure-controlled non-return valve (6) or directly the piston (5) performing the function of a slotted timing gear in co-operation with passages of the cylinder (16). The solution can be applied in four-stroke and two-stroke spark-ignition and compression ignition engines.
