Abstract: Disclosed is a polymerization inhibitor of N-vinyl pyrrolidone monomers and use thereof. The polymerization inhibitor is selected from an inorganic weak acid potassium salt and/or an organic acid potassium salt. The polymerization inhibitor is added to N-vinyl pyrrolidone monomers, and is sealed and preserved under the protection of inert gas, wherein the addition amount of the polymerization inhibitor is 0.005-0.2% by mass with respect to the mass of the N-vinyl pyrrolidone monomers. Directly adding the polymerization inhibitor into the N-vinyl pyrrolidone monomers in proportion can inhibit the self-polymerization of the N-vinyl pyrrolidone monomers, and hence extend the shelf life. The chromaticity and toxicity of the monomers can be reduced to a great extent. The polymerization inhibitor can be used directly during solution polymerization without being removed, and does not affect the chromaticity of a polymerization solution.

Abstract: A method for recovering valuable metals and simultaneously preparing ceramsite by roasting cyanide tailing belongs to the area of comprehensive recovery and high value utilization of metallurgical waste residue. In this method, cyanide tailings, bentonite, calcium chloride, coal powder and albite are mixed by ball milling according to certain weight ratio to get a mixture. After drying and roasting twice, dust is collected from the roasted ash, the obtained polymetallic ash is collected and treated. The secondary calcined material is cooled to obtain ceramsite. The invention volatilizes and recovers the valuable metal in the roasting and sintering process of cyanide tailings and directly prepares the ceramsite through reasonable batching, which achieves the effect of recycling cyanide tailings and high-value utilization, can create good economic and environmental benefits, and has significant effect of energy saving and consumption reduction.

Abstract: A zero insertion force socket (1) for electrically connecting a central processing unit (CPU) with a printed circuit board (PCB) comprises a base (10), a cover (20) slidably mounted on the base, and terminals (30) received in the base, a rotatable cam actuator (40) for actuating the cover to slide on the base, a protecting mechanism (50) and a washer (60) mounted between the cover and the base. The protecting mechanism comprises a cover plate (51) in the cover and a bottom plate (52) in the base. The cover plate defines an elongated slot (512). A pair of opposite cam stoppers (515) extends upwardly from one side of the slot. The cam actuator has a protrusion (45) abutting against one of the cam stoppers during rotation.

Abstract: A zero insertion force (ZIF) socket (1) is for electrically connecting a central processing unit (CPU) with a printed circuit board (PCB). The socket includes a dielectric base (10), a cover (11) slidably mounted on the base, an actuator (13) rotatably mounted between the base and the cover, and a multiplicity of terminals (12) received in the base for electrically connecting pins of the CPU with the PCB. The cover defines a multiplicity of holes (1110) therein, for receiving the pins of the CPU therethrough. A plurality of blind cavities (1111) is defined in a face of the cover that abuts the base. A cross section of each blind cavity is round. The cover is formed as a single piece by molding. The blind cavities can reduce deformation of the cover, thus enhancing uniform flatness thereof. This helps ensure accurate and reliable engagement between the base and the cover.

Abstract: A packing device (1) is for accommodating electrical connectors (2). The packing device includes a body (10), and a plurality of cavities (11) defined in the body. Each cavity is bounded by a bottom wall having a higher front end (12) and a lower rear end (13), a front wall (14) adjacent the front end, and a rear wall (15) adjacent the rear end. A through slot (18) is defined in the front end. When the packing device filled. with electrical connectors reaches a corner or curve of an assembly line, a rearward one of two adjacent cavities tilts. The front wall at the rearward cavity bends into the slot at the rearward cavity, instead of contacting and bending or distorting the rear wall at the adjacent forward cavity. Thus, the electrical connector in the forward cavity can be reliably picked up by a suction machine of the assembly, line.
