Abstract: FIELD: passenger vehicles.  
     SUBSTANCE: invention relates to methods for ensuring passive safety of passenger vehicles. The vehicle seat contains a seat cushion, a seat back and a seat base consisting of brackets, cross members, linings and reinforcements. The bracket is divided into two parts by a notch ending in a Z-shaped notch that does not reach the upper edge of the bracket for a certain distance, forming a bridge that can break when a certain bending load is applied to the bracket. The pads are welded to the side and horizontal surfaces of the bracket. In this case, the edge of the overlays adjacent to the recess follows its contour. The cross members are welded to the bracket. The reinforcements are welded at one end to the vertical flange of the bracket, the other to the horizontal flange of the bracket and partially to the cross members. 
     EFFECT: safety of the vehicle passenger in the event of an accident is increased.

Abstract: FIELD: foundry. 
     SUBSTANCE: invention relates to foundry and can be used for production of steel tubing billet with increased radiation resistance. Melt is poured into rotary around horizontal axis at speed of 650 rpm shape. During the whole period of formation of the workpiece, a mixture of dispersed particles is fed into the melt flow, consisting of (wt% of the mass of the molten metal) tungsten carbide (0.8-1.2), boron carbide (0.4-0.7), yttrium oxide (0.05-0.95). Supply of particles is carried out simultaneously. Since the disperse particles fed have different density, under action of centrifugal forces they are distributed in different layers of the formed steel workpiece. 
     EFFECT: successive finding of particles in surface, middle and inner layers of tube billet provides effective prevention to radiation radiation effect, which considerably increases service life of article in aggressive medium.

Abstract: FIELD: mining industry.  
     SUBSTANCE: invention relates to a method for increasing the productivity of wells. The first and second slugs are pumped into the calculated area of the producing and/or injection well. In productive formations with loose weakly cemented porous and/or fractured reservoirs, the presence of a zone of residual oil saturation, the presence of a zone of maximum water saturation, the presence of an undersaturated transition zone, a zone of maximum oil saturation is determined, taking into account the presence or absence of clay bridges at the boundaries of the zone of maximum water saturation and the transition zone. The water-saturated zone is cut off from the zone of maximum oil saturation with the possibility of ensuring the inflow of oil into the productive reservoir from the subzone of high oil content. Polymer resin is used as the first slug. A hardener is used as the second slug. The second slug is pumped in an amount from 0.1 to 500% of the volume of the first one. A separation solution or composition is injected with the possibility of separating the first and second slugs in a given interval of cleaning the affected object from the products of oil precipitation. A buffer solution or composition is injected with the possibility of cleaning or washing the impact zone. A reinforcing solution or composition is injected with the possibility of retaining the first and second slugs in a given interval. The injection of separation, buffer and reinforcing solutions or formulations is carried out simultaneously or separately. The separation solution or composition is pumped in an amount from 0.1 to 2500% of the volume of the first slug. The buffer solution or composition is pumped in an amount from 0.1 to 5000% of the volume of the first slug. The reinforcing solution or composition is pumped in an amount from 0.1 to 5000% of the volume of the first slug. The permeability in the zones allocated by oil saturation is preliminarily determined. After injection, the well is transferred to the hydrocarbon inflow mode. The method is applicable for horizontal wells, fractured-porous, porous, loose and weakly cemented rocks.  
     EFFECT: increase in the productivity of the well, taking into account its geological and field features by reducing the water content of products, increasing the inter-repair period of operation and oil flow rate.

Abstract: The signal term to be transmitted to a railroad traction vehicle is formed in a signaling system in that each element, from a destination element back to a start element has a respective top speed assigned thereto as an identification. The identification is transmitted element-by-element back to the start element and is devalued during relaying thereof when the identification is greater than that prescribed for a travel path element having a lower assigned top speed so that the identification received at the start element indicates the top speed admissible for the route. The admissible top speed is then converted into a corresponding signal term.
