An outer through hole is formed in the position, right opposite to the lock cylinder body, of the shell cover, an inserting and matching groove is formed between the shell and the shell cover, two guide blocks are symmetrically installed on the shell at the bottom end of the inserting and matching groove, the two guide blocks are jointly and slidably connected with an anti-drilling plate, and the anti-drilling plate is in meshed connection with a transmission assembly rotationally installed in the shell. And the transmission assembly is connected with a driving unit. The anti-theft lock has the advantages of being capable of preventing the lock cylinder from being exposed and damaged, convenient to operate manually or remotely, good in protection performance and stable and reliable in structure.

This invention discloses a reactor for water-gas shift reaction and its application. The reactor is suitable for water-gas shift reaction processes containing gaseous and liquid reactants. A reaction chamber is set inside a hollow, sealed cylinder formed by the reactor walls. The reaction chamber is a hollow, sealed chamber surrounded by porous material as its wall surface. A gaseous reactant inlet pipe penetrates the reactor wall and extends into the upper part of the reaction chamber, a liquid reactant inlet pipe penetrates the reactor wall and extends into the cylinder, and a reaction product outlet pipe penetrates the reactor wall and extends into the lower part of the reaction chamber. The catalyst for the water-gas shift reaction is packed in the reaction chamber. The water-gas shift reaction can be carried out under near-isothermal conditions. Water in the liquid reactant does not need to be pre-vaporized and is directly fed into the reactor in liquid form, saving the energy consumption required to transport the corresponding amount of water vapor. Simultaneously, a high molar ratio of water to carbon monoxide is maintained within the reactor, promoting complete conversion of carbon monoxide.

A monolithic perforated plate for forming a plurality of electron beams of a multi-beam electron beam system is described. The monolithic perforated plate is composed of a monolithic construction element having individual functional planes and having a plurality of pores. In addition to the plurality of pores, the monolithic porous plate does not contain cavities. The monolithic porous plate design is used for better performance and longer service life.

The application provides a manufacturing method of a hemi-aluminum spherical shell, which comprises the following steps: firstly, a hemi-core shaft ball is obtained through super-precision turning, so as to ensure the size precision and roughness of the outer spherical surface; secondly, a special fixture is manufactured through precise turning, milling and super-precision turning; then, the hemi-core shaft ball is assembled on the conical surface of the special fixture through negative pressure adsorption and adhesive fixation; the hemi-aluminum spherical shell is obtained through super-precision turning; and finally, the inner and outer stoppers are processed and assembled to form a complete spherical shell to load specific substances. The manufacturing method of the hemi-aluminum spherical shell can obtain a high-precision hemi-aluminum spherical shell, which has better size precision consistency and higher wall thickness uniformity than the hemi-aluminum spherical shell manufactured by using a traditional mold, and the wall thickness uniformity of the hemi-aluminum spherical shell is better than 3 mu m, so that the yield can be improved and the cost can be reduced.
