Abstract: FIELD: rotary equipment. 
     SUBSTANCE: rotary-plate device is designed to convert reciprocating motion into rotational motion without using a crank mechanism. The rotary-plate device can be used as either a pump, or a compressor, or a hydraulic pneumatic drive, or a silent vacuum cleaner. The rotary-plate device includes stator (2), brackets with support rollers, side covers, rotor (1), and at least two piston plates (8). Stator (2) has a cylindrical shape with inlet and outlet (6), (6'). Brackets with support rollers move on the outer surface of stator (2). Side covers are made with annular grooves. Rotor (1) is located non-coaxially relatively to stator (2) to form chambers of unequal volume. Rotor (1) is made with at least two radial grooves. At least two piston plates (8) are installed in radial grooves with the possibility of reciprocating motion. Working piston plates (8) have a length greater than the length of rotor (1) body, protruding from rotor grooves. Working piston plates (8) enter radial grooves of support disks installed on both sides of rotor (1) so that grooves of support disks coincide with rotor grooves. Working piston plates (8), leaving grooves of rotor (1) as much as possible, remain in grooves of support disks. For tightness, additional seal is inserted into radial grooves. Annular grooves in side covers are used to distribute the pressure that occurs under plates, and are made at the level of radial grooves located in the rotor.  
     EFFECT: increase in the tightness, as well as an increase in the useful internal volume and service life of the device.

Abstract: FIELD: mechanical engineering. 
     SUBSTANCE: invention relates to the field of mechanical engineering and can be used in the manufacture of an investment casting pattern. The method for producing an investment model includes dosed supply of a waxy model material in the form of a powder with a fraction of at least 0.4 mm into a mold and rotation of the mold relative to its axis. A mold with an inner radius of at least 3 cm is used, which is rotated until it reaches 3000-4000 rpm, which is sufficient to increase the density of the model material, at which it ceases to be loose after the mold rotation stops. The mold is stopped, metal balls with a diameter of 1-12 mm are placed in it in an amount sufficient to cover the inner surface of the investment model in at least one layer, then the mold is rotated at a speed of 3500-4000 rpm. Metal balls increase the effect of centrifugal force on the model material, due to which it is compacted at a reduced speed of rotation of the mold. The spherical shape ensures uniform distribution of metal balls on the inner surface of the model. 
     EFFECT: elimination of shrinkage, warping of the surface and layering of the model.
