Definitions

• the burden of the burden does not involve any useful blows here, which, despite the irreplaceable mass of the machine, reduces its capacity.
• the manual pneumatic safety device is also known; it is protected by the shock of an effective operation (see patent
• the main task was to create such a manual manual pneumatic protected machine, which was activated at the expense of compensation
• another element 7 was installed, made, for example, from rubber.
• step 3 (Fig. ⁇ ) has been completed in separate phases, which go through step 17
• the 23 variant is used, which are in the 24th phase (Fig. 1, 3); Nicholas Vulkul 12, cylindrical part 5, for example
• the 30th elements of the 7th railway unit ⁇ are communicated with the atmosphere,
• the manual manual pneumatic protection device provided in FIG. 1 operates the following way.

• Shenzhen 3 continues its continuous movement and pressure at the 22nd place. Before proceeding, the pressure is higher than the previous one. The valve 18 is in the first place, but this is not done until the channel 19 is left to the next.

• the invention is most expediently used in machines used in the literature for the use of bulk mixtures, in addition to a small variety. At this point, it is carried out completely and is connected to the calibrated section of the boiler. Such a construction does not only reduce vibration, but also significantly reduces the length of the machine.
• the invention may also find application in the building and installation, and also in other cases where there is a risk of failure.
