Abstract: FIELD: agricultural engineering. 
     SUBSTANCE: invention relates to sowing machinery used mainly for sowing seeds of grass, shrubs and sushrubs on noncultivated land areas, for instance, on devastated pastures and meadows with native grass stand, i.e. pod-bearing plants, (including common licorice), meadow grasses, their mixtures, shrubs and subshrubs. Proposed sowing unit contains tractor, hopper for seeds and fertilizers with seed-sowing mechanisms, seed tubes, colters, closers and covering roll. Unit is furnished with tandem-mounted and mechanically connected rolls. Front roll in direction of movement of sowing unit plays the part of colter group. Colters are made in form of soil cutting tool secured on surface of front roll in direction of movement and installed over perimeter of roll at equal angular pitch, being displaced through half of pitch in adjacent rows. Each soil cutting tool is placed in socket for re-adjustment and demounting. Socket is made in form of hollow cylinder. Axis of symmetry of each socket is displaced from radial direction of its rolling through angle of 15-35 o . Soil cutting tool is locked in socket by dowel installed in coaxial holes of socket and soil cutting tool. Holes in socket are made parallel to roll generating surface. Each soil cutting tool is essentially stepped trunnion. Group of holes for re-setting in socket is made in trunnion of smaller diameter in soil cutting tool. End face of detachable trunnion is provided with ring cutting edge and conical cavity. Seed tubes in seed and fertilizer hopper are located in section line of soil cutting tool on surface of front roll. Closers are secured on second roll in direction of movement. 
     EFFECT: provision of sowing of seeds of grass, shrubs and subshrubs on devastated pastures, floodplain meadows and firths, possibility of creating new grasslands.

Abstract: FIELD: rubber industry. 
     SUBSTANCE: invention discloses a method for recovering synthetic rubbers from latexes stabilized by carboxylic acid soaps, which consists in action of mineral acid and organic amine coagulant on antioxidant-containing rubber latex. Organic amine coagulant is added in amount 0.01 to 1.0% in two steps: first portion constituting 50-90% of total amount of coagulant is added directly to latex and resulting mixture is stirred for at least 0.5 h at 20-70°C, after which second portion of coagulant or its mixture with mineral salt (coagulant/salt weight ratio from 1:0 to 1:15000) is fed into coagulation apparatus jointly with recycling serum at latex-to-serum weight ratio between 1:1 and 1:2. Rubber is thus obtained in the form of homogeneous porous crumb.
