Proposed nut runner comprises case to accommodate motor 1, high-rpm low-torque and low-rpm high-torque rotation branches 13, 19, 27, 32, spindle rpm shifting mechanism engaged with motor 1, two clutches 10, 16, of which one of half-couplings being rigidly fitted on input shaft and another one on output shaft to reciprocate thereon, intermittent motion mechanisms 47, 49, 51, 53, two differential mechanisms 7, 22 and reduction gears 12, 18, 26, 31 articulated with differential mechanisms 7, 22. Besides, it incorporates extra clutches 24, 29, limit stops 54, 55, 56, 57 in contact with every clutch and clutch half-coupling operation pulse counter 58 fitted to interact with one of said clutches. Note here that all clutches 10, 16, 24, 29 are arranged downstream of differential mechanisms 7, 22 and articulated with reduction gears 72, 18, 26, 31. |

Processing machine driven by motor Invention relates to machine building and may be used in manual angular grinders. Proposed machine comprises motor with polar tips to transmit magnetic field blower impeller to create cooling airflow. Machine cooling air duct section is composed by air guide element that covers, at least partially, said polar tips. The latter are located, at least partially, outside said air duct. At least one guide vane is made at air guide element to extend into said air duct. |

Food product loaf cutting method as well as cutting machine Food product loaf is supplied to the cutting device by means of a supplying device by means whereof the loaf is cut into slices, strips or cubes. During supplying motion the food product loaf is fixed by means of a vacuum gripper being supplied with the food product loaf. In the inner space of the vacuum gripper contact element one provides for depression impacting in one suction area on the contact element on one fixation area on the food product loaf surface. The suction area is divided into at least two separate suction subareas. The inner space of the contact element is divided into at least two inner subspaces, respectively. The suction subareas border on each other, respectively, along the contact line ensuring the possibility of separate fixation areas formation on the food product loaf surface. |
