Abstract: A surface cleaning apparatus includes a housing including an upright handle assembly and a base mounted to the upright handle assembly. The surface cleaning apparatus is further provided with a brushroll and a fluid delivery system comprising a fluid supply chamber and a fluid dispenser configured to dispense fluid to the brushroll.

Abstract: A winch for securing a load to a vehicle a is disclosed. The winch includes a mounting bracket with opposed flanges. The winch further includes a drum extending along an axis between a first end and a second end. The drum is mounted relative to the opposed flanges so that the drum is rotatable about its axis. The winch includes a gear received on the drum and a worm configured to mesh with the gear so that a rotation of the worm causes a rotation of the gear. The winch further includes a clutch assembly between the drum and the gear. The clutch assembly is biasable between a first configuration in which the gear is fixed relative to the drum about the axis of the drum and a second configuration in which the gear is rotatable relative to the drum about the axis of the drum.

Abstract: A self-adaptive control system comprises a feeding device, a rotary coder, a displacement sensor, a hydraulic regulation system and a controller, wherein, the input end of the controller is electrically connected with the rotary coder, the displacement sensor, a first oil pressure sensor and a second oil pressure sensor respectively, and the output end of the controller is electrically connected with a solenoid directional valve via an interlocking controller; the controller takes the bearing force of piston rods and the rotation speed and the rotation speed change rate of a feeding knife roller as input variables and takes the positions of the piston rods as an output variable, to establish a fuzzy control model of the feeding mouth opening of the feeding device, the extension and retraction of the piston rods in a left oil cylinder and a right oil cylinder under hydraulic driving are regulated actively by controlling a three-position four-way solenoid directional valve, and thereby self-adaptive control of
