Alkali metal chlorates are produced by electrolyzing an anolyte contained in an anode compartment of an electrolytic cell, the anode and cathode compartments separated by means of a permselective membrane having low alkali metal ion transport efficiency. The final chlorate product can be directly crystallized from the electrolyzed anolyte or fed directly to a chlorine dioxide generator. Alternatively, a microporous, hydrophilic diaphragm can be substituted for the permselective membrane provided that the catholyte compartment is maintained at a higher hydraulic pressure than the hydraulic pressure in the anolyte compartment.

A graphene-iron oxide complex consists of graphene and needle-like iron oxide nanoparticles grown on a surface of the graphene, and a fabricating method thereof includes (A) preparing a reduced graphene dispersed solution, (B) mixing the dispersed solution with a solution containing iron oxide precursors to prepare a mixture, (C) stirring the mixture to prepare a graphene-iron oxide dispersed solution containing the graphene-iron oxide complex that needle-like iron oxide nanoparticles are grown on the surface of the graphene, and (D) separating the graphene-iron oxide complex from the graphene-iron oxide complex dispersed solution.

A torque converter including an impeller clutch with a first portion connected to a cover for the torque converter and a second portion connected to an impeller; and a lever element in contact with the clutch and displaceable to multiply a first force applied to the lever element for operation of the clutch. In some aspects, the converter includes an impeller piston plate engaged with the lever element and displaceable to apply the force to the lever element. In some aspects, the torque converter includes a torus and a charge chamber for the impeller clutch, a second force is associated with a hydraulic pressure to prevent cavitation in the torus, a third force is required to operate the impeller clutch to transmit a desired torque across the impeller clutch, and the multiplied force is at least equal to a sum of the second force and a third forces.

The invention discloses a rigid polyvinyl chloride material reinforced by hollow glass microballoons and a preparation method thereof. The material comprises the following components in weight portion: 100 portions of polyvinyl chloride resin powder, 1 to 50 portions of the hollow glass microballoons, 0.1 to 10.0 portions of coupling agent, 0.5 to 3.0 portions of heat stabilizer, 0.2 to 5.0 portions of lubricant, 0.1 to 5.0 portions of processing modifier, and 0.1 to 10.0 portions of impact modifier. Through coupling compatibility and a distribution technology, the preparation method comprises the steps of compounding and directly injecting the hollow glass microballoons and the resin, and then processing the mixture to prepare the hollow glass microballoon reinforced rigid polyvinyl chloride material which has the advantages of higher impact resistance strength, hydraulic pressure resistance and explosion strength, higher size stability, and the like. The preparation method has the advantages that the preparation method uses simple and practicable processes to deal with compatibility problem, accords with design requirements of industrialized production processes at the same time of meeting requirements on product properties, can achieve large-scale continuous production, and has relatively low production cost and stronger industrialized popularization.

In a shock absorber of a vehicle, when a moving speed of a piston rod in relation to a cylinder tube is slow and first and second input forces are externally applied to the shock absorber, damping forces of pressure side and extension side first damping force generating devices are larger than that of pressure side and extension side second damping force generating devices. On the other hand, when the moving speed is fast, the damping forces of the pressure side and the extension side second damping force generating devices are larger than that of the pressure side and the extension side first damping force generating devices. A gas enclosure chamber filled with gas is connected to a first chamber through a free piston.
