Granted: 2021-12-08
Abstract: FIELD: material plane stress state determination. 
     SUBSTANCE: invention is intended to determine the plane stress state of an anisotropic material. The substance of the invention lies in the fact that the pulses of ultrasonic longitudinal and transverse waves are introduced into the loaded object and its unloaded analogue by the emitting electro-acoustic transducers, the reflected bottom pulses are received by the receiving transducers, the transit times of these pulses in the loaded and unloaded objects are measured, the changes in the delays of the transmitted pulses are determined and, from their difference, the values ​​of stresses are determined, taking into account the acoustic anisotropy by using additional acoustoelastic coefficients, and the temperature - by using thermoacoustic coefficients of the dependence of the velocities of elastic waves of various types on the temperature of the object material in the calculation algorithms. In this case, to refine the results of determining the plane stress state, the difference in thermoacoustic coefficients of transverse waves polarized along different axes of anisotropy of an anisotropic material is taken into account. 
     EFFECT: improving the accuracy of determining the plane stress state of acoustically anisotropic materials.

Abstract: FIELD: medical technology. 
     SUBSTANCE: invention relates to medical technology and can be used for the treatment of snoring, syndrome of increased resistance of the upper respiratory tract, obstructive sleep apnea and hypopnea. An intraoral device for the treatment of snoring and obstructive sleep apnea includes maxillary and mandibular mouth guards made of plastic material. On the mandibular mouthguard on both sides in the area of ​​the corresponding first molars from the vestibular side in the direction of the maxillary mouthguard, two abutment protrusions are made. On the maxillary mouthguard, movable pushers are fixed on the sides with the possibility of adjustable translational movement towards the protrusions of the mandibular mouthguard. The distal sides of the projections and the medial sides of the pushers touch each other in a closed position. The medial sides of the pushers and the distal sides of the protrusions are made in the form of conjugate arcs of different curvature, the surfaces of which, when the caps are closed, are equidistant to each other and are made according to an individual shape along the trajectory of movement of the lower jaw of each individual person, corresponding to the shape of the line reflecting the path of movement of the interincisal point of the lower jaw in the sagittal plane from the maximum forward extension of the lower jaw to the position of the maximum open mouth. The protrusions on the mandibular mouthguard in a vertical section are made with an offset from the lateral surfaces of the maxillary mouthpiece at a distance of 0.5 to 2 mm. 
     EFFECT: creation of a mouthguard with an individual physiological shape of the contacting surfaces of the pusher on the maxillary mouthguard and a projection on the mandibular mouthguard, which ensures uniform distribution of pressure on the contacting surfaces between the distal sides of the projections on the mandibular mouthguard and the medial sides of the pushers on the maxillary mouthpiece.

Title: Device and method of measuring the gravitational field
Inventor: VERYASKIN ALEXEY VLADIMIROVICH
IPC: G01V7/02
Filed: 1995-10-04
Abstract: The device and method of measuring the gravitational field includes a superconducting string (1), which is fixed to the both ends, forming part of a close superconducting circuit, inductively coupled with two induction solenoids (Ld1, Ld2). Displacement of the string in reply to gravitational field is recovered by two magnetic flux converters, each containing a signal coil and two search coils (Lp1, Lp2). The pair of search coils is placed in two perpendicular planes, creating two individual measuring channels. Two arms of each flux converter are balanced so as to transform the oscillation amplitude into the output tension for their own asymmetric modes of the spring. The output tension of each channel is used for distribution formation of the feedback current (Iy1, Iy2) parallel to the string, in a close proximity to it. Adjusting the feedback current, there can be adjusted the relaxation time and the resonance frequency of the first asymmetric mode of the string, while the symmetric modes remaining unchanged, that improves the device sensibity to the gravitation gradient.
