Abstract: The invention relates to a serpentine inspection robot mechanism for lifting cage guide driven by magnetic wheels, comprising a magnetic wheel drive part and a pitching yawing part, wherein the magnetic wheel drive part comprises a worm and gear transmission mechanism (I) and a magnetic wheel driving mechanism (II), and the pitching yawing part comprises a pitching yawing mechanism (III). Magnetic wheels are driven by the worm and gear transmission mechanism (I) and the magnetic wheel driving mechanism (II), while the pitching and yawing control of the robot are realized by the pitching yawing mechanism (III). The serpentine robot driven by the magnetic wheels (22) resolves the problems that the efficiency of ordinary serpentine robot is low, and it is difficult for the simple-wheel-type robot to span the large gap and to reach some concealed corners, with the cage guide of the lifting machine sucked by the magnetic wheels (22).

Abstract: The invention relates to methods of determining sodium ions in a sample, wherein the ions are contacted with a compound having chromophoric moiety and an ionophoric moiety, where the ionophoric moiety interacts with the sodium ions present in the sample, resulting in the chromophoric moiety changing its radiation absorption properties in the ultraviolet and visible regions of the spectrum. For example, a change in an intensity of an absorption maximum is measured and the ion concentration is determined accordingly.

Abstract: An elastic sieving method and corresponding large-sized elastic vibration screen. The present invention utilizes a screening surface and a separate sieving machine. A screen mat located on the sieve box is connected to multiple small rectangular screens. While the machine is vibrating, the resonation of screen rods located on the screen mat connected by small rectangular screens are initiated to screen the material and to cause the vibration of the whole vibration screen and realize the conveyance and lamination of materials. Because the screening surface is in a state of resonance, the vibration strength is strong enough to prevent the screen meshes from becoming plugged, allowing for high sieving efficiency. A bearing in the sieving mechanism is installed with a vibration damping ring, placing the bearing in a resonant state, allowing for a low dynamic stress level, which satisfies the process requirement for large-sized vibration screen excitation units with a screening surface as wide as 4800 mm.
