A depth limiting device includes a braking structure; a limited shrinking structure, the limited shrinking structure including a part that surrounds a moving object and being in a home position or a compressed position; and a structure adapted for pushing the limited shrinking structure to the home position. The braking structure brakes the moving object such that the moving object moves together with the depth limiting device. When the moving object enters into a subject, the part of the limited shrinking structure is pressed against the subject, and the limited shrinking structure moves from the home position to the compressed position and stops the moving object from entering further into the subject.

The present invention refers to the field of flue gas purification, which discloses a method and apparatus for capturing carbon dioxide and producing sulfuric acid by sodium bisulfate; using a three-format electrodialysis apparatus to convert the desulfurized by-product NaHSOinto HSOwhile capturing COin the flue gas in the cathode chamber. Under the action of electric field drive and ion exchange membrane, HSOenters the anode chamber to generate HSOand is concentrated, and Naenters the cathode chamber to generate NaOH; the flue gas containing COto be treated is introduced from the cathode chamber and absorbed by NaOH. The invention provides a simple, green, and economic proceeding method to capture the carbon dioxide in the flue gas during the comprehensive utilization of sodium bisulfate solution, which is of better environmental benefits and improvement of the flue gas treatment technology and reducing the pressure of desulfurization gypsum treatment.

A depth limiting device includes an axial braking structure; a limited shrinking structure, the limited shrinking structure surrounding a moving object, and being in a home position or a compressed position; and a structure adapted for pushing the limited shrinking structure to the home position. The axial braking structure axially brakes the moving object such that the moving object moves together with the depth limiting device, and when the moving object enters into a subject, the limited shrinking structure is pressed against the subject, moves from the home position to the compressed position, and stops the moving object from entering further into the subject.

A depth limiting device for a drill includes a main body, an axial braking structure, and a limited shrinking structure. The axial braking structure is attached to the main body. The limited shrinking structure surrounds a drill rod of the drill, is slidably attached to the main body, and is in a home position or a compressed position. The axial braking structure axially brakes the drill rod such that the drill rod moves together with the depth limiting device. When the drill rod enters into a subject, the limited shrinking structure is pressed against the subject, moves from the home position to the compressed position, and stops the drill rod from entering further into the subject.

A spontaneous-extending and anti-rotation scoliosis correcting system comprises pedicle screws and a plurality of correcting rods locked with the pedicle screws. Each correcting rod includes at least one sleeve and at least one inserting rod which can be inserted into the sleeve. The inner wall of the sleeve and the inserting rod are the same in shape and are in clearance fit. A positioning mechanism for restricting the relative rotation of the inserting rod with respect to the sleeve is arranged on a matching surface between the inserting rod and the sleeve. The scoliosis correcting system has the benefits of ensuring the lateral stability and the anti-rotation function for scoliosis correction; having the performance of spontaneous extending along the growth direction of the spine; and ensuring both the short-term operating effect and the long-term curative effect.
