Abstract: A chemical process utilizing electrodialysis in a flow cell with cation and anion selective ion exchange membranes to produce sulfuric acid from phosphogypsum and gypsum, and centrifugal separation to reduce radioactive phosphogypsum into a liquid slurry (mainly calcium hydroxide) capable of sequestration. Reactants used are water, phosphogypsum or gypsum, and sodium carbonate.

Abstract: Disclosed is a fastening structure for a seating foam, comprising a foam and a reinforcement fabric, and characterized in that the fastening structure is directly provided at a reinforcement fabric at a location corresponding to a fastening position, and is connected to the reinforcement fabric. The fastening structure of the present invention simultaneously meets two functional requirements of a foam, namely reinforcement of a side B of the foam and fastening of an exterior side A of the foam. The novel fastening structure of the present invention saves space, is thin and light, enhances the strength of the foam against a pull-out force, and optimizes a foam production process.

Abstract: Password-retrieving-apparatus for coded lock, a movable adjusting rod is arranged in the lock body; a small spring is arranged between the adjusting rod and a lock cover; the adjusting rod is provided with a protruding point; an inner wheel is provided with an avoidance clamping slot and a limit; a lock cylinder is driven to rotate under the rotation of a spare key; the lock cylinder is engaged with a bump on a toggling disk for driving the inner wheel to rotate in a staggered manner; the lock body moves relatively under the action of a big spring; the adjusting rod moves inwards under the action of the small spring; and the toggling disk is rotated to drive the inner wheel to rotate; the protruding point on the adjusting rod and the limit in the inner wheel are clamped.

Abstract: The present disclosure provides data processing methods and apparatuses. One exemplary data processing method includes: acquiring interview data about candidates of a set historical period, the interview data of the set historical period including interview data of separate interview rounds, and the interview data of each interview round including a candidate, an interviewer, and an interview result; and evaluating interviewers based on differences of interview results of different interviewers. The present disclosure can automatically use massive historical interview data to evaluate the interview abilities of interviewers. On one hand, the workload of manual evaluation of the interviewers is reduced, thereby reducing the interviewer team management cost of an enterprise. On the other hand, the evaluation of the interview abilities of the interviewers is more objective and accurate, helping the enterprise to choose excellent interviewers and thus improving the interview performance of the enterprise.
