The invention provides a metal surface treatment agent composed of aqueous solution or aqueous emulsion containing ionic liquid. The metal surface treatment agent comprises the ionic liquid, silicate or silane coupling agent, water-soluble chitin or chitosan, corrosion inhibitor, stabilizer, pH modifier, wetter, coalescing agent, antioxidant, ethanol and water, the ionic liquid is room-temperature ionic liquid consisting of nitrogenous heterocyclic compound cations and inorganic or organic anions, one or more of nanoscale titanium dioxide, zirconium oxide or zirconium fluoride is uniformly mixed into the silicate or silane coupling agent by the weight equivalently accounting for 3%-25% of that of the silicate or silane coupling agent. A chemical conversion coating is formed on a metal surface by the metal surface treatment agent, can inhibit corrosion of the metal surface, and has a fine coating performance. The metal surface treatment agent is used for treating cold-rolled plates, galvanized plates and aluminum plates, and the metal surface treated by the metal surface treatment agent has the coating adhesion force equivalent to that of a metal surface treated by a phosphorus-containing metal surface treatment agent.

A surface cleaning apparatus comprises a base comprising an AC suction motor and a portable cleaning unit removably mounted on the wheeled base and comprising an energy storage member and a portable cleaning unit suction motor that is operable on DC power. The AC suction motor provides motive power when the surface cleaning unit is switched on and when the portable cleaning unit is mounted on the base. The portable cleaning unit suction motor provides motive power when the portable cleaning unit is switched on and when the portable cleaning unit is removed from the base. Alternately, the portable cleaning unit suction motor may be operable on DC power when removed from the wheeled base and may be operable on power provided by the wheeled base when mounted on the wheeled base.

A dense phase pump for particulate material includes a pump chamber wherein material flows into the pump chamber under negative pressure and flows out of the pump chamber under positive pressure. A plurality of pinch valves are provided to control flow of material into and out of the pump chamber. The pinch valves are operated independent of each other and of the pump cycle rate. A modular design of the pump is provided.

The invention provides antistatic flame retardant fiber and preparation method thereof. The cross section of the fiber is a sheath-core structure; a sheath layer contains conductive powder and halogen-free flame-retardant polyamide 6; a core layer is polyester, the polyamide 6 or a polyamide 66, wherein the weight ratio of the sheath layer to the core layer is (15:85) to (25:75), and the conductive powder accounts for 5-7% of the total mass of the sheath layer. Since conductive power is added in the halogen-free flame-retardant polyamide 6, so that the fiber is endowed with the antistatic function and the flame-retardant function, particularly the electrostatic absorption of dust, caused by fiber, can be reduced because of anti-static function, and then the cleanness and favorable cleanable performance of a fiber product can be kept; and meanwhile the fiber with the sheath-core structure can still keep favorable mechanical properties and spinning property. While keeping better antistatic and flame-retardant properties and mechanical properties, the fiber reduces the production cost and improves the processing properties, thereby being more user-friendly for downstream users.

The agitator comprises a rotating shaft 3 extending vertically inside an agitating vessel 2, and a flat paddle blade 4 mounted on the rotating shaft 3. The flat paddle blade has a bottom flat paddle blade portion 4a extending outwards from the bottom of the rotating shaft 3 and a rectangular upper flat paddle blade portion 4b extending upward from an upper part of each side end of the bottom flat paddle blade portion 4a. The dimensional ratio (b/a) of the blade diameter (b) of the bottom flat paddle blade portion 4a to the inner diameter (a) of the agitating vessel 2 is from 0.6 to 0.9, and the dimensional ratio (d/c) of the height (d) of an upper flat paddle blade portion 4b to the height (c) of the bottom flat paddle blade portion 4a is from 1 to 4. A passage 12 is formed inside the rotating shaft 3 and flat paddle blade 4 for passing a coolant medium therethrough.

An upright surface cleaning apparatus is operable in a floor cleaning mode and an above floor cleaning mode. The surface cleaning apparatus includes a first upstream air flow path extending from the dirty air inlet of the floor cleaning head to a downstream air flow path, and an above floor cleaning member removably mounted to the surface cleaning apparatus. The above floor cleaning member includes an alternate dirty air inlet. The surface cleaning apparatus also includes a second upstream air flow path extending from the dirty air inlet of the above floor cleaning member to the downstream air flow path. The surface cleaning apparatus also includes a valve selectively connecting the first upstream air flow path in flow communication with the downstream air flow path when the dirty air inlet of the above floor cleaning member is placed in a storage position on the upright surface cleaning apparatus.

An oven muffle having a receiving space, at least some regions of which are delimited by wall elements, in which at least one of the wall elements is permeable to IR radiation or has a region that is permeable to IR radiation. In the oven muffle, the cooking performance is successfully improved while also providing an easily cleanable interior because a reflecting element that reflects IR radiation is positioned in the region of the outer surface of the wall element on a side oriented away from the receiving space.
