The device comprises a motor driving, via a belt transmission, the flow pulse generator (3) connected permanently with actuator. The feeding for flow pulse generator (3) is supplied to port (6), and the outflow to the reservoir occurs via port (7). On the circumference of rotor (17) of the flow pulse generator (3), a plurality of grooves is made. Groove (10), on one side, is connected permanently with passage of port (6), and on the other side, depending on position of rotor (17), it can be connected with arms of the flow guide, Groove (9), on one side, is connected permanently with passaoe of port (7), and on the other side, depending on position of rotor (17), it can be connected with arms of the flow guide. Passage (12) depending on position of rotor (17), is connected directly with groove (8) or with groove (9).

Abstract: 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).

Abstract: 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).

Abstract: 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 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 stroke, and in production of a combustible mixture by mixing with air compressed in the combustion chamber.

Abstract: A hydraulic supply system of a pulsatory press has two pumps (4 and 5) supplying through non-return valves (8 and 9) and through overflow valves (10 and 11), two slide dividers (17 and 19). The divider (17) in the position I directs oil to the working space V.sub.n under the servo-motor piston, whereas the divider (19) directs oil to the rotary divider (20) wherefrom a pulsating stream of oil gets into the working space under the part of the piston of a smaller diameter and into the run-off. The divider (17) in the position II directs oil to the space V.sub.p over the servo-motor piston at a simultaneous connection of the space V.sub.w via a slide valve (24) with the run-off, whereby the value of pressure in the space V.sub.p over the servo-motor piston is limited by means of an overflow valve (15).The conduit supplying oil from the divider (19) to a rotary divider (20) is connected via a cut-off valve (22) and a throttle valve (23) with a conduit supplying oil from the divider (17) to the space V.sub.

Abstract: A semi-conductor controlled rectifier (SCR) d.c. interrupter in which any (optional) number m of identical, self-contained and parallel connected phases each form an identical series connection of a semi-conductor controlled retifier (Th.sub.1) . . .

Abstract: A four-stroke multicylinder internal combustion engine having first and second cylinders in which combustion takes place in alternation in the cylinders at intervals of 360.degree. of crankshaft revolution. A duct connects the working spaces of the cylinders for flow of exhaust gases between the cylinders and a fuel line is connected to the duct for supplying fuel thereto so that the fuel is transported with the flow of exhaust gases from one cylinder to the other.
