Instruments for Measuring the Gradient of the Absolute Values of the Magnetic Field
Magnetic prospecting is widely used for mineral exploration and the study of the structure of the earth's surface. For the realization of magnetic reconnaissance are applied the instruments sensitive to the magnetic field, that give the possibility to measure different components of magnetic field and its gradients. In this article, three new devices are considered that allow measuring the gradient of the absolute values of the magnetic field.
New Type of Unipolar Generator
Application in the unipolar engines of samariumcobalt magnets opens the new prospects of creating the engines with the large rotational moment, since. such magnets possess the great magnetic field, which cannot they will reach in other magnets. However, the creation of engines are connected with the need of using the brushes, friction against the external rim of the revolving disk and against its axis. Since the speed of rotation of the rim of disk is great, brushes rapidly are worn out, what is an essential drawback in this construction. In the article is represented the construction and the experimental mock-up of the unipolar generator, in which there are no brushes. This is achieved by the use of two ball bearings of those inserted in each other.
Unipolar Engine of Mende
Application in the unipolar engines of samariumcobalt magnets opens the new prospects of creating the engines, with the large rotational moment, since. such magnets possess the great magnetic field, which cannot they will reach in other magnets. However, the creation of engines with the large diameter of disk runs into the great difficulties connected with the fact that industry does not let out magnets with the large diameter. In the article is proposed the new construction of unipolar engine, in which for creating the magnetic field are used the magnets of small diameter.
Polarizing Magnetic Field Generator
Around the conductor with the current there is a magnetic field. If with the aid of the external current source was excited in the solenoid, or cylinder, thus it will be such to magnet with the appropriate poles. In the article is described the polarization generator of magnetic field, in which the magnetic field is created with the aid of the rotation of the polarized conducting cylinder.
Electroform Generator Mende
In the article the survey of the existing constructions of high-voltage electrostatic generators is carried out. Are described the new types of the generators of Mende, the using laws of electrostatic induction and the tests of the experimental are carried out the models of such generators.
Magnetic Gauge of the Displacements
There are different methods of displacement measurement to which should be carried the mechanical methods, when are used rules, compasses, micrometers and the mechanical standards of length. There are also electrical methods, when length is compared with the frequency of resonant circuit, or cavity resonator, whose reactive elements (capacity or inductance) depend on frequency. There are also interference methods, when displacement is compared with the wavelength of electromagnetic radiation. The emission of lasers most frequently for these purposes is used. In the article the new method of measurement of displacement with the aid of the Hall effect is examined.
The Electrostatic Generator of Mende
The survey of the methods of separation and accumulation of charges is carried out and the existing constructions of electrostatic generators are examined. Is proposed the new method of the separation of electric charges in the liquids, which flow in the magnetic field. Is given the schematic of the electrostatic generator, based on the application of a method of the magnetic separation of charges, and they are represented the results of experimental studies.
New Types of the Electrostatic Generators
One of the first electrostatic generators is Calvin's dropper, which invented the lord Calvin in 1863. This generator gave the possibility to obtain voltage of up to 20 kV. Further development of electrostatic generators was the invention of the electric generator, developed between 1880 - 1883 the British inventor By James by Whimshurst. This generator gave the possibility to obtain voltage of up to 100 kV and it is above. Wide practical use in the accelerating technology obtained de Graaf's generator. This is the generator of the high voltage, the operating principle of which is based on the electrization of that moving dielectric tape. Such generator was developed American by the physicist By Robert van de Graaf in 1929 for year it made possible to obtain the voltage to 80 kV. In 1931 - 1933 they built the more powerful generators, which made it possible to reach voltage in 1 MV and 7 MV respectively. In the article are described three new constructions of the electrostatic generators, one of which is pulse.
A New Way to Separate Anions and Cations
Electrolysis is currently widely used for the production of various substances, as well as for the isolation of individual elements from the composition of chemical compounds, which by electrolysis are decomposed into anions and cations. For this purpose, electrolysis of aqueous solutions is used, which makes it possible to carry out such a separation in a simple way. For this, electrolyzers are used, where a current is passed through aqueous solutions, while the anions are grouped near the cathode, and the cations are near the anode, from where they are taken. The article considers a new method for the separation of anions and cations, which is based on the polarization of electrolytes. This method differs from the known ones in that it does not require passing current through the electrolyte, which reduces the cost of the production process
Development and Increase in the Reliability of the Small Storage Batteries, Utilized for the Nourishment of the Mobile Radio-Technical Devices
Given the description of construction are given the fundamental characteristics of the small storage batteries Li of group. The fundamental characteristics of the nickel metal hydride storage batteries are given Ni-MH. Development and application of such storage batteries significantly increased the reliability of small mobile radio sets, in particular, cell phones.
