Definitions
- the proposed invention is available to the device for production of oil, and more to the device for the calculation of the interior of the unit
- n is the height of the numeral head
- B the diameter of the honorary head “* • - the angle of inclination of the cutting element (spiral) to the right side of the head (corner of the knife); and also, an increase in the length and shaft to a length is additionally stabilizing, an increase in their weight is more / a1 and an increase in the length of the pitch with a more durable length
- ⁇ is the length of the shaft
- b - the length of the optional directional stabilization
- ⁇ is the mass of the shaft
- ⁇ 1 - the mass of additional directional stabilization; ⁇ is the step length of a knife with an involute ⁇ ; 5 ⁇ - Georgia ⁇ ; "3.14; ⁇ - diametr of a clear head.

- n is the length of the shaft
- b the length of the additional directional stabilization
- ⁇ is the mass of the shaft
- ⁇ is the step length of a knife with an involute ⁇ ile
- - B - the diameter of the numeral head The main and auxiliary stabilizing devices 7, 8 and the depth-filter 2 have a maximum size in the cross-section less than the maximum size of the 4th chapter.
- the mobile connection of the depth-of-field-adapter 2 to the shaft I may be completed, for example, with a threaded end 22 and a locked post 23.
- Articles 15, 16 may be performed from an anti-friction material, for example, plastic.
- the convenience of the device for calculating the internal areas of the pipes and the accessories of the devices is based on an excep- tion.
- the device operates the following way. With a closed buffer valve, the device is placed in the lubricator (not shown), which is then sealed. The cushioned valve is turned off and the tractor 10 is supplied with a quick-release fluid pump (not shown), it is not supplied with a liquid cleaner. Due to the fact that the consumables are also available, they are designed for easy use of 4.5 stainless steel spacers, and 4 - 7 - Relative friend of friend.
- the devices are empty to a certain depth. Then, it releases a bill of goods 10. In this case, the “black” cutting of services is carried out on 13th of March.
