Abstract: The present invention discloses a catalytic hydrogenation method for carbon nine resin, comprising the following steps: 1) adding a Pt—W—Y/?-Al2O3 catalyst in the first half of a fixed bed, adding a Pd—Zr—Nd/?-Al2O3 catalyst in the second half of the fixed bed, and feeding hydrogen for reduction; and 2) catalytic hydrogenating the pretreated carbon nine resin in the fixed bed. In the present invention, different catalysts capable of reacting under the same catalytic conditions are added in the first and second halves of the fixed bed, and the two different catalysts play different roles, and can be active and complementary to each other under the same conditions. The synergistic effect of the two catalysts plays a good catalytic role. Moreover, the production process is simplified, and the production cost is saved.

Abstract: A disclosed apparatus may include at least one touch sensor and an integrated film that includes at least one antenna, wherein the integrated film is at least partially disposed on the at least one touch sensor such that the at least one touch sensor operates as a radiating element for the at least one antenna. Various other apparatuses, systems, and methods are also disclosed.

Abstract: An air guide ring for an air conditioner outdoor unit is provided. The air guide ring includes an air guide ring body. An air guide channel is defined in the air guide ring body. The air guide ring body includes a first limiting portion and a second limiting portion. The first limiting portion and the second limiting portion are configured to fit with a fixing member of the air conditioner outdoor unit and to implement bi-directional limiting, so as to prevent inward contraction deformation and outward expansion deformation of the air guide ring body from occurring.

Abstract: The invention discloses a healthy sucrose product and a method for fabricating the same. The sucrose product mainly consists of sucrose and L-arabinose, wherein sucrose has a mass percentage of 70-99.99%, and L-arabinose has a mass percentage of 0.01-30%. The method for fabricating the sucrose product mainly comprises the steps of: sufficiently mixing solid sucrose and L-arabinose crystals; or mixing solid sucrose and L-arabinose solution and then drying the resulting solution. In the present healthy sucrose product, L-arabinose is added into sucrose for suppressing invertase's activity, so that the human body's absorption of sucrose is reduced to achieve a healthy intake of sugar. In this manner, the problems of hyperglycemia, dental caries, and obesity, which otherwise may occur after the intake of sucrose, are solved.

Abstract: The present invention discloses an individualized orthodontic appliance with axis correction functions, comprising No. 1-7 individualized lingual brackets connected in series by an archwire. Each individualized lingual bracket includes a base plate and a bracket body connected with the base plate. In the No. 1-7 individualized lingual brackets, the underside of the bracket body of at least two of the individualized lingual brackets is disposed with a crimpable hook with a through hole and the through holes are connected in series by an ortho-axial wire. In this invention, the underside of the bracket body is disposed with the crimpable hook with the through hole and the ortho-axial wire is used to pass through the through holes. In this way, the underside of the bracket body can produce the corresponding orthodontic force while the crown of tooth is moving during the orthodontic treatment. The positions of the teeth roots can also be gradually corrected.

Abstract: The present invention discloses a universal lingual bracket system, comprising No. 1-7 universal lingual brackets connected in series by an arch wire. The universal lingual bracket includes a base plate and a bracket body portion that are integrated as a whole. A mesh bottom is arranged on the base plate and the mesh bottom is integrally molded with the base plate. The mesh bottom, the base plate and the bracket body portion are integrally molded. In addition, the mesh bottom is in the structure of an interlaced woven wire mesh, so that the universal lingual brackets have strong capability to be against the teeth surfaces and they are unlikely to come off. Even if they come off, they will not damage the mesh bottom. The mesh bottom can be used again once it is treated by sandblasting. The universal lingual bracket system provided by the invention has the advantages that it can be securely and easily installed and has high durability; therefore it is applicable to various universal lingual appliances.

Abstract: The present invention discloses a method for manufacturing a positioning tray and a bracket with a positioning hook for manufacturing the positioning tray. The method for manufacturing the positioning tray comprises the following steps: acquiring an original dental impression and an ideal dental impression; transforming the ideal dental impression to a three-dimensional digital model and drawing each bracket body; drawing a positioning hook on the bracket body; making a wax pattern of a bracket with the positioning hook by using a wax pattern machine; casting, with the wax pattern as a mould core, a blank of the bracket with the positioning hook which then receives surface treatment; after the surface treatment, assembling the bracket with the positioning hook to the original dental impression and performing film lamination to obtain a positioning tray, and finally removing the positioning hook to obtain the bracket matching the positioning tray.
