Abstract: FIELD: railways. 
     SUBSTANCE: group of inventions relates to the field of the superstructure of a railway track, in particular to methods of frictional compensation of movements of a continuous-welded rail track, as well as to devices for its implementation. The device contains rails, lodgements on the sleeper grid, compensation blocks and fixing bolts. The bushings of the vertical supports of the lodgements and the body of the frictional compensation unit are equipped with threads. The rails are fixed in the cradle, while bolts are screwed on one side, and the block body on the other. The compression force of the rail web is created through floating elongated pads. The compressive force creates a frictional force and prevents the axial movement of the rails relative to the sleeper grid.

Abstract: A method and apparatus are disclosed for degassing the pressure fluid of a hydraulic system, in which a vacuum is maintained in the free space above the pressure fluid in the fluid reservoir of the hydraulic system by a vacuum pump. The vacuum pump has a selective pumping action, by virtue of which permanent gases present in the free space are withdrawn but vapors of the pressure fluid present in the free space are not withdrawn. Pressure fluid entering the reservoir from the hydraulic system is passed over a degassing surface to promote separation of the permanent gases in the pressure fluid from the fluid. A compensating line is provided between the vacuum pump and the reservoir for returning to the reservoir the nominal amounts of pressure fluid withdrawn from the reservoir by the pump. Valves provided in all fluid lines leading to and from the reservoir maintain the vacuum in the reservoir during system shut-downs.
