The electroforming technique of electrolytic deposition of metals on the surface of various objects (matrices) with the aim of obtaining accurate metal copies were first developed and applied in practice in 1838 by the Russian scientist, academician B. S. Jacobi. With his direct participation had made many great works of art, statues and bas-reliefs for St. Isaac’s Cathedral, Hermitage Museum, Winter Palace, Peter and Paul Cathedral, including the famous Quadriga to front of the Bolshoi theater in Moscow.

The first development, which we publish, is a universal glider of class “Standard”, called “pennant-4”. Characteristics, it is approaching to widespread machine “Brazil”, but has a number of original nodes, that facilitate and accelerate Assembly and disassembly. The device has been extensively tested in various flight conditions. His flight main advantages: the minimum gliding angle, extended speed range, the ability to execute turns of small radius on all speed range, softness, and ease of management.
No one is surprised that for drilling different holes require different tools. The bit set can not do, does not matter. The trouble is that the tool change takes a lot of precious minutes. How to avoid this! In various companies are innovators in different ways solve this problem. There was, for example, drill bits with a stepped diameter, one such tool allows you to drill small and large holes. And where this range should be really very great work on the turret with permanently fixed at their range of drills.
F. Slavin from the village Malesina Kurgan region gathered his hands, using the components and mechanisms of various scrapped or abandoned motor equipment.
For grinding of surfaces of metal parts to a mirror Shine created a lot of mechanical devices. However, most of them are designed for processing flat surface, in an extreme case, with only a small curvature. And how to be with different matrices and punches, press forms — after all, they must be treated as carefully!
The normal brush is good for painting only flat surfaces. That’s why innovators design for complex works of a special brush. The original, with the unusual instrument, outwardly, no resemblance to the brush, though intended to perform it functions. He developed in the Institute Kazorgtechstroy and is designed for painting pipes oil compositions.
