An aquarium cleaning device for cleaning an inner surface of an aquarium wall includes a flexible cleaning body and a flexible handle member. The cleaning body and the handle member are magnetically attracted to each other. The flexibility in the cleaning body and the handle member allows the cleaning device to contour and conform to curved surfaces in the aquarium tank. The flexibility of the cleaning body and handle member are achieved by areas of flexibility having alternating recesses and fins.

Embodiments relate to an apparatus for descaling a vessel. The apparatus includes a frame having a frame top and a frame bottom, the frame including a longitudinal axis running from the frame top to the frame bottom. The apparatus includes an outrigger stabilizing assembly attached to the frame. The outrigger stabilizing assembly has a plurality of arms configured to extend and retract radially with respect to the longitudinal axis to abut against a wall of the vessel. The apparatus includes a turret attached to the frame bottom. The apparatus includes a hammer assembly pivotally attached to the turret. The hammer assembly has an extendable and retractable boom pivotally attached to the turret. The boom has first and second ends, and there is a reciprocating hammer pivotally attached to the second end of the boom.

An automatically-cleanable thickening performance evaluation instrument for drilling LCMs includes a cleaning device, a kettle body, a thickening motor, a heating component, a test ending component, a top cover, and a bottom cover, where upper and lower ends of the kettle body are both opened; the kettle body is arranged in a third bearing inner race, a third bearing outer race is connected to a first limb, and the first limb is configured to limit a position of the kettle body; and the kettle body is detachably connected to the thickening motor and driven by the thickening motor to rotate. The instrument can realize electric heating and air pressurization to simulate the underground environment, and the kettle body can be completely sealed, such that a measured thickening time is close to an actual thickening time. Moreover, the instrument can be automatically cleaned at the end of a test.

A roasting and glazing apparatus includes a roaster, an agitator mounted within the roaster bowl for mixing a mixture of nuts and sugar during a roasting or glazing operation, a heater controlled to heat the roaster bowl during the roasting or glazing operation, and a cover removably mounted to the roaster bowl. The cover includes a reservoir for receiving water from a user and restricting water flow from the reservoir into the mixture of nuts and sugar in the roaster bowl. The cover and the roaster bowl together define a vent on a side of the cover opposite the reservoir. The vent is configured to direct steam out of the roaster bowl in a direction away from the reservoir.

A robot includes a truss assembly, a walking assembly, a power unit, and a rack including a guide pillar, a second link. The truss assembly is disposed on the top of the rack. The walking assembly is disposed in the rack and fixedly connected to the rack through a bearing. The power unit is disposed on the rear end of the rack. An oil tank is provided with a hole. The truss assembly is configured to place the robot into the oil tank through the hole. The walking assembly is configured to drive the robot to move along the axis of the oil tank and to prevent the robot from toppling in the oil tank. The power unit is configured to clean the inside of the oil tank. The walking assembly includes two active walking assemblies, a drive assembly, and a folding assembly.
