Exemplary embodiments are directed to a motorized brush. The brush includes a housing and a bristle assembly disposed at least partially within the housing. The bristle assembly includes a support frame, and a bristle belt capable of being actuated to rotate relative to the support frame in a motorized manner.

Automatic cleaning apparatus for solar collectors, photovoltaic panels, windows and similar surfaces, consisting of an elastic brush 10 formed by an elastic cord 20 having bristles 30 inserted therein. The ends of the cord are hooked to discs 50 through hooks 40 that rotate through two motors 60 driven synchronously and controlled by a central unit 70. The cord vibrates and a circularly polarized stationary wave is established therein. The brush 10 is secured to a cart 80 that moves through wheels 90 driven by motors 100 across the photovoltaic panel.

Brush systems for transferring preforms along a rail include a cam including a follow extending from the cam, and a bracket positioned adjacent the cam. The bracket includes a slot for receiving the follow of the cam. The brush system also includes a brush assembly coupled to the bracket. The brush assembly includes a yoke positioned adjacent to and operably connected to the cam, a brush holder coupled to the yoke, opposite the cam, and a plurality of brushes positioned within the brush holder. Additionally, the brush system includes a motor coupled to and configured to rotate the cam. Rotation of the cam causes the bracket and the brush assembly to move in a first direction, and the brush holder and the plurality of brushes of the brush assembly to move in a second direction substantially perpendicular to the first direction.

A process unit includes a rotatable image bearing member, a charging roller, a brush unit including a brush and a holding member, a regulation member, and an urging member. The holding member includes a first force-receiving portion configured to receive a force in the first direction from the urging member, a second force-receiving portion configured to receive a force in the second direction from the regulation member, and a third force-receiving portion configured to receive a force in the second direction from the brush substrate. The first force-receiving portion, the second force-receiving portion, and the third force-receiving portion are disposed on one end side with respect to a center of the holding member in a rotation axis direction of the charging roller, and are arranged in an order of the second force-receiving portion, the first force-receiving portion, and the third force-receiving portion from the one end toward the center.

The present disclosure is directed to an improved direct smelting process for improving the efficiency of energy/heat recovery from hot smelter offgas for the purpose of steam raising and power generation. In examples, the formation of alkali sulfate accretions in the temperature range 500-1000 C. are removed by introducing a mechanical sweep-cleaning system to an offgas duct of the smelter. The sweep-cleaning system comprises at least one central rotating shaft with chains, with each chain optionally having an accretion-removal member at its distal end. When rotated, the chains lift and the accretion-removal member sweeps the walls of the duct to remove the accretions.
