The paper shows an algorithm for determining the load on the electric motor of run-out conveyor starting from determination of the first moment of no load operation during slab conveying, slipping torque of the rollers along the surface of the conveyed billet and ending with the choice of the electric motor. It also covers an algorithm for strength calculations of the run-out conveyor roller, which includes the calculation of the moments and forces acting on the conveyor roller and its supports, the calculation of static strength and torsion strength, calculation of roller deflection of the conveyor rollers as well as the selection and verification calculation of conveyor roller bearings.

Proper determination of the shear strength of the backfill body used to fill the subsidence is the basis for subsidence restoration and the stability analysis of materials. This study developed a shear strength calculation model for the backfill body by introducing adhesive friction theory into the shear strength analysis. A direct shear test was performed in the laboratory to verify the proposed method. Test results suggested that the shear strength calculation method based on adhesive friction theory can calculate the variation in the actual contact area between grains in the tested samples undergoing shearing and estimate the peak shear strength. The actual contact area was divided into two components, namely, adhesive contact area Arm and contact area reduction caused by shear displacement, which exhibited a maximum at Armax. The shear strength values calculated by this method were smaller than laboratory values, and their differences increased with the rock proportion in the backfill body. The differences between the theoretical and experimental values of shear strength increased with the rock grain size. The results of theoretical calculation, combined with the results of laboratory experiments, can provide support for the proper determination of shear strength of the backfill body.

The design of the roll-type electric baromembrane apparatus is developed. High quality separation of solutions is achieved by combining electric baromembrane separation with electrode cooling using collectors for the flow of cooling water with an independent arrangement of drainage channels of the near-cathode and near-anode permeate. A method is proposed for calculating the strength of the body of an electric baromembrane apparatus with the determination of the required thickness of the body wall and fiberglass flanges.

An extension and generalization of the theory of multipolar interaction is developed which includes the effects of anisotropic polarizability, anisotropic pair distribution function, and orientational correlations. A formulation of overlap interaction is evaluated using a simple inverse power-law model. The spectral integral and the first moment of the absorption coefficient α(ω) are computed for a multicomponent gas. Anisotropic 'interference' terms couple the multipolar components so that the expressions are not simply sums over individual multipolar contributions. The theory presented here has been successfully applied in earlier published work to the determination of the multipole moments and molecular parameters of linear and tetrahedral molecules.
