Abstract: A device implementing polariton optical neural network, comprising: Input layer (100) consisting of optical elements ensuring linear pre-processing and distribution of input optical signals (102), middle layer (104), consisting of nonlinear optical elements, realizing nonlinear transformation of the pre-processed input signals (106), output layer (108) consisting of linear optical elements, realizing linear transformation of the signals that had been transformed nonlinearly (110) and generating output signals, passive optical systems (114) optically coupling the input layer (100), the middle layer (104), the output layer (108) characterized in that the nonlinear transformation in the middle layer occurs as a result of interaction of pre-processed input signals (106) with a nonlinear element or elements in the form of an optical microcavity or multiple optical microcavities hosting exciton-polaritons.

Abstract: A device for recycling molding sand, the device containing a base; a vibratory reclaimer; a pneumatic cascade classifier serially connected at its upper section to the vibratory reclaimer; and at least two generators of vibrations. The vibratory reclaimer contains: a vertical column, the vertical column being hollow and cylindrical in shape, having an axis of rotation, and a side wall with at least one pour-out hole, wherein the pour-out hole is connected with a transport trough, and the transport trough is rigidly mounted and rises in a spiral fashion along the side wall and at a top end passes through a channel extending to a feeding screw for feeding recycled molding the to the pneumatic cascade classifier.
