摘要： Internal stresses are measured in cylindrical objects, such as axles, shafts and tubes made of material with varying non-uniform homogeneaus mechanical properties.
The method consists in that a beam of ultrasonic waves is thrown onto the surface of a cylindrical object being tested, said beam being refracted at an angle of 90 degrees. Next the times of passage for every type of waves are measured. On the basis of the calculated differences of the times of passage with a standard the absolute values of components of stresses are calculated.
The method is applicable for non-destructive testing of properties and structure of materials and products.

摘要： The present invention relates to a spring having two states of stable equilibrium. The spring is to be used for accumulation of elastic strain energy and for setting the mutual position of movable co-acting parts. The inventive spring consists of at least one pair of elastic strips (1) and two shaped elements (3) determined by the angles (γ), the elastic strips (1) of each pair being connected to one another, preferably at their ends, with arms of the shaped elements (3) in such a way that between the neighbouring sides of the strips (1), there is a slot (2) of length (a) and a variable width (b). The strips (1) are situated in relation to one another in such a way that they are inclined at an angle as determined by the inclination angle of the shaped elements (3). The invention is applicable for clamping various parts, for example to close kinematic chains, for the accumulation of elastic strain energy in bumpers, or for unsuring the state of equilibrium of component parts of various mechanisms.

摘要： This present invention solves the problem of bending objects, particularly flat parallel ones, without employing an external force.
The method according to this present invention involves subjecting the material of the object bent to a repetitive, two-phase heating and cooling process.
During the first phase, the material undergoes heating with a concentrated stream of energy causing a thermal effect along the predetermined bending line and a partial plasticising, melting and flowing out in the region of the bending line.
On the other hand, the material is subjected in the second phase to being cooled at ambient temperature or, additionally, in a stream of a blown air, thereby causing the previously heated material to shrink along fibres in the direction perpendicular to the bending line due to the internal stresses created by the thermal shrinkage of the material in the heated region, and thus the deformation of the material to be permanently changed.
The method is suitable for bending metal objects.
摘要翻译：本发明解决了在不使用外力的情况下弯曲物体，特别是平行的物体的问题。根据本发明的方法涉及将物体的材料经历重复的两相加热和冷却过程。在第一阶段期间，材料以浓缩的能量流经受加热，从而沿着预定弯曲线产生热效应，并在弯曲线的区域内部分塑化，熔化和流出。另一方面，材料在第二相中经受在环境温度下的冷却，或另外在吹入空气流中，从而使预先加热的材料沿着垂直于弯曲线的方向沿纤维收缩，由于到由加热区域中的材料的热收缩产生的内部应力，从而使材料的变形永久变化。该方法适用于弯曲金属物体。
